Systematic screening for prostate cancer is widely recommended in candidates for renal transplant at the time of listing. There are concerns that overdiagnosis of low-risk prostate cancer may result in reducing access to transplant without demonstrated oncological benefits. The objective of the study was to assess the outcome of newly diagnosed prostate cancer in candidates for transplant at the time of listing, and its impact on transplant access and transplant outcomes according to treatment options. This retrospective study was conducted over 10 years in 12 French transplant centers. Patients included were candidates for renal transplant at the time of prostate cancer diagnosis. Demographical and clinical data regarding renal disease, prostate cancer, and transplant surgery were collected. The primary outcome of the study was the interval between prostate cancer diagnosis and active listing according to treatment options. Overall median time from prostate cancer diagnosis to active listing was 25.0 months [16.4-40.2], with statistically significant differences in median time between the radiotherapy and the active surveillance groups (p = .03). Prostate cancer treatment modalities had limited impact on access and outcome of renal transplantation. Active surveillance in low-risk patients does not seem to compromise access to renal transplantation, nor does it impact oncological outcomes., (© 2023 The Authors.

Objective: To analyze de novo graft carcinoma characteristics from our updated national multicentric retrospective cohort., Methods: Thirty-two transplant centers have retrospectively completed the database. This database concerns all kidney graft tumors including urothelial, and others type but excludes renal lymphomas over 31 years., Results: One hundred and fifty twokidney graft carcinomas were diagnosed in functional grafts. Among them 130 tumors were Renal Cell Carcinomas. The calculated incidence was 0.18%. Median age of the allograft at diagnosis was 45.4 years old. The median time between transplantation and diagnosis was 147.1 months. 60 tumors were papillary carcinomas and 64 were clear cell carcinomas. Median tumor size was 25 mm. 18, 64, 21 and 1 tumors were respectively Fuhrman grade 1, 2, 3 and 4. Nephron sparing surgery (NSS) was performed on 68 (52.3%) recipients. Ablative therapy was performed in 23 cases (17.7%). Specific survival rate was 96.8%., Conclusion: This study confirmed that renal graft carcinomas are a different entity: with a younger age of diagnosis; a lower stage at diagnosis; a higher incidence of papillary subtypes., (Copyright © 2022 Elsevier Inc.

Background: Due to increased risk of pyelonephritis, patients with intestinal reconstruction of the lower urinary tract (IRLUT) have long been advised against kidney transplantation. The aim of this study was to compare the outcomes of transplantation between patients with IRLUT and patients with normal LUT (NLUT) using propensity score matching method., Methods: The study included 23 kidney recipients with IRLUT matched to 46 kidney recipients with NLUT using known allograft survival and pyelonephritis risk factors as covariates. One-, 5-, and 10-year graft survival, pyelonephritis, and surgical complications occurrence and graft function were compared., Results: One-, 5-, and 10-year graft survival were 96%, 91%, and 63% in the IRLUT group and 96%, 88%, and 70% in the NLUT group, respectively ( p  = 0.72). Patients with IRLUT had increased cumulative risk of pyelonephritis at 10 years (70% vs. 19%; log-rank < 0.01) without impacting graft function or rejection occurrence. There was no difference in overall surgical complication, but patients with IRLUT had more urological complications than patients with NLUT (62% vs. 28%; p  < 0.01)., Conclusions: Our case-control study consolidates the results regarding the safety of transplantation in patients with IRLUT using a strong validated matching method and provides new insights regarding graft function, pyelonephritis, and surgical complications in this population., Competing Interests: The authors declare no conflicts of interest., (© 2021 The Authors.

Introduction: The shortage of kidney transplants encourages the expansion of the limits of eligibility criteria for donation. Many donors who are brain dead display acute renal failure at the time of death; is this a real contraindication to harvesting? The aim of this study was to assess kidney graft survival from donors after brain death with confirmed acute renal failure, with or without anuria previous donation., Materials and Methods: All of the transplants performed in two university hospitals between 2010 and 2017 were analyzed retrospectively. All patients who underwent single kidney transplant from a brain-dead donor with acute renal failure (ARF) were included in this study. ARI was defined here by a decrease over 50 % of glomerular filtration rate (GFR) to a threshold below 45mL/min/1.73 m 2  at the time of kidney procurement. Kidney graft survival, incidence of delayed graft function (DGF) and the GFR at 12 months were analyzed. Analysis of kidney transplant survival based on pre-implantation biopsies was additionally done., Results: One hundred and sixty four patients were transplanted with a kidney from donor with ARF during the selected period. At the admission in ICU the average GFR was 67,7±19mL/min/1,73m 2 . At the time of donation, the average age of donors was 56.4±17.7 years, the GFR was 33.7±8.0mL/min/1.73 m 2 16 % of donors were anuric. Cold ischemia time (CIT) was 16.8±5.0hours. The average age of recipients was 55.6±14.1 years. 81 % of the cases were primary transplants. Graft function took place within 7.8±9.4 days after transplantation. There were two non-primary functions (PNF). One hundred and fifty two patients (93 %) had a functional graft at 12 months. The mean GFR at 12 months was 46.8±20.1mL/min/1.73 m 2  and 122 patients (73 %) had a GFR greater than 30mL/min/1.73 m 2 . Seventy-one percent of preimplantation biopsies revealed acute tubular necrosis (ATU); no cortical necrosis was observed. Survival of theses grafts was 85 %, comparable to the total population of study (P=0,21) CONCLUSION: The acute renal failure of the brain-dead donor should not alone be systematically a contraindication to harvesting and kidney transplantation., (Copyright © 2020 Elsevier Masson SAS.

Objective: To propose surgical recommendations for urothelial carcinoma management in kidney transplant recipients and candidates., Method: A review of the literature (Medline) following a systematic approcah was conducted by the CTAFU regarding the epidemiology, screening, diagnosis and treatment of urothelial carcinoma in kidney transplant recipients and candidates for renal transplantation. References were assessed according to a predefined process to propose recommendations with levels of evidence., Results: Urothelial carcinomas occur in the renal transplant recipient population with a 3-fold increased incidence as compared with general population. While major risk factors for urothelial carcinomas are similar to those in the general population, aristolochic acid nephropathy and BK virus infection are more frequent risk factors in renal transplant recipients. As compared with general population, NMIBC in the renal transplant recipients are associated with earlier and higher recurrence rate. The safety and efficacy of adjuvant intravesical therapies have been reported in retrospective series. Treatment for localized MIBC in renal transplant recipients is based on radical cystectomy. In the candidate for a kidney transplant with a history of urothelial tumor, it is imperative to perform follow-up cystoscopies according to the recommended frequency, depending on the risk of recurrence and progression of NMIBC and to maintain this follow-up at least every six months up to transplantation whatever the level of risk of recurrence and progression. Based on current data, the present recommendations propose guidelines for waiting period before active wait-listing renal transplant candidates with a history of urothelial carcinoma., Conclusion: The french recommendations from CTAFU should contribute to improve the management of urothelial carcinoma in renal transplant patients and renal transplant candidates by integrating both oncologic objectives and access to transplantation., (Copyright © 2020.

Objective: To define guidelines for the management of renal cell carcinoma of the native kidney (NKRCC) in kidney transplant (KTx) recipients and renal cell carcinoma (RCC) in end-stage renal disease (ESRD) patients candidates for renal transplantation., Method: A review of the literature following a systematic approach (Medline) was conducted by the CTAFU to report renal cell carcinoma epidemiology, screening, diagnosis and management in KTx candidates and recipients. References were assessed according to a predefined process to propose recommendations with the corresponding levels of evidence., Results: ESRD patients are at higher risk of RCC with a standardized incidence ratio of approximately 4,5 as compared with general population. NKRCC tumors occur in 1 to 3 % of KTx recipients with a 10 to 15-fold increased risk as compared with general population, especially in patients with acquired multicystic kidney disease. Most authors suggest yearly monitoring of the native kidneys using ultrasound imaging. Radical nephrectomy (either open or laparoscopic approach) is the preferred treatment of NKRCC in KTx recipients and RCC in ESRD. Surveillance in a valid option in small or cystic renal masses. In the localized setting, change in immunosuppressive therapy is not recommended besides perioperative avoidance of mTOR inhibitor to limit morbidity. CTAFU does not recommend a mandatory waiting time after nephrectomy for RCC in ESRD patients candidates for renal tranplantation when tumor stage

The medical device M101 is an extracellular hemoglobin featuring high oxygen-carrying capabilities. Preclinical studies demonstrated its safety as an additive to organ preservation solutions and its beneficial effect on ischemia/reperfusion injuries. OXYgen carrier for Organ Preservation (OXYOP) is a multicenter open-label study evaluating for the first time the safety of M101 added (1 g/L) to the preservation solution of one of two kidneys from the same donor. All adverse events (AEs) were analyzed by an independent data and safety monitoring board. Among the 58 donors, 38% were extended criteria donors. Grafts were preserved in cold storage (64%) or machine perfusion (36%) with a mean cold ischemia time (CIT) of 740 minutes. At 3 months, 490 AEs (41 serious) were reported, including two graft losses and two acute rejections (3.4%). No immunological, allergic, or prothrombotic effects were reported. Preimplantation and 3-month biopsies did not show thrombosis or altered microcirculation. Secondary efficacy end points showed less delayed graft function (DGF) and better renal function in the M101 group than in the contralateral kidneys. In the subgroup of grafts preserved in cold storage, Kaplan-Meier survival and Cox regression analysis showed beneficial effects on DGF independent of CIT (P = .048). This study confirms that M101 is safe and shows promising efficacy data., (© 2020 The American Society of Transplantation and the American Society of Transplant Surgeons.)

Background: Robot-assisted laparoscopic radical prostatectomy (RARP) has been poorly studied in men with renal graft., Objective: To determine the predictive factors for oncologic outcomes and complications after RARP in renal transplants recipients (RTRs)., Design and Participants: A retrospective multicenter controlled study identified all RTRs who had undergone RARP between 2008 and 2016 in 2 experts departments. All RTRs were matched 1:1 with patients who had also undergone RARP but with no history of renal transplant (control group)., Intervention: Robot-assisted laparoscopic radical prostatectomy., Outcome Measurements: Incontinence, oncologic outcomes, and complications according to the Clavien-Dindo classification., Statistical Analysis: Comparisons of the quantitative variables using Student's t tests, and comparisons of the qualitative variables using χ2 tests. Statistical analyses were performed using SAS (version 9.3). Independent risk factors of biochemical recurrence (BCR), postoperative complications, or incontinence were searched by using a multivariate linear regression., Results: Twenty-seven RTRs were included in the transplant group and compared with 27 men in the control group with similar preoperative characteristics. Univariate analysis showed a shorter BCR-free survival in RTRs, with 26.9 months vs 49.3 months in the control group (P = .018). BCR rate was similar in each group (7.4% vs 11.1%, P = .639). No difference between groups was showed for immediate postoperative complications (29.6% vs 22.2%, P = .279). Multivariate analysis showed that a renal graft history was an independent risk factor of shorter BCR-free survival (hazard ratio = 4.291; 95% confidence interval, 2.102-8.761 and P < .001). Even if it is the first comparative study on this topic, the low number of men included is the main limitation of our study., Conclusions: These findings show the reliability of RARP in RTRs. The rate of BCR does not appear more frequently but BCR-free survival seems shorter in these patients. A prospective comparative study remains necessary with more patients to confirm our results., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Simultaneous heart-kidney transplant (HKTx) is a valid treatment for patients with coexisting heart and renal failure. The aim of this study was to assess renal outcome in HKTx and to identify predictive factors for renal loss. A retrospective study was conducted among 73 HKTx recipients: Donors' and recipients' records were reviewed to evaluate patients' and renal transplants' survival and their prognostic factors. The mean follow-up was 5.36 years. Renal primary non-function occurred in 2.7%, and complications Clavien IIIb or higher were observed in 67.1% including 16 (22%) postoperative deaths. Five-year overall survival and renal survival were 74.5% and 69.4%. Among survivors, seven returned to dialysis during follow-up. The postoperative use of ECMO (HR = 6.04, P = 0.006), dialysis (HR = 1.04/day, P = 0.022), and occurrence of complications (HR = 31.79, P = 0.022) were independent predictors of postoperative mortality but not the history of previous HTx or KTx nor renal function prior to transplantation. History of KTx (HR = 2.52, P = 0.026) and increased delay between the two transplantations (HR = 1.25/hour, P = 0.018) were associated with renal transplant failure. HKTx provides good renal transplant survival and function, among survivors. Early mortality rate of 22% underlines the need to identify perioperative risk factors that would lead to more judicious and responsible allocation of a scarce resource., (© 2019 John Wiley & Sons A/S.

Purpose: The aim of the current study was to determine the outcomes of botulinum toxin A intradetrusor injections in adult patients with spina bifida., Materials and Methods: All patients with spinal dysraphism who underwent intradetrusor injections of botulinum toxin A from 2002 to 2016 at a total of 14 centers were retrospectively included in analysis. The primary end point was the global success of injections, defined subjectively as the combination of urgency, urinary incontinence and detrusor overactivity/low bladder compliance resolution. Univariate and multivariate analysis was performed to seek predictors of global success., Results: A total of 125 patients were included in study. The global success rate of the first injection was 62.3% with resolution of urinary incontinence in 73.5% of patients. All urodynamic parameters had improved significantly by 6 to 8 weeks compared to baseline, including maximum detrusor pressure (-12 cm H 2 O, p <0.001), maximum cystometric capacity (86.6 ml, p <0.001) and compliance (8.9 ml/cm H 2 O, p = 0.002). A total of 20 complications (3.6%) were recorded for the 561 intradetrusor botulinum toxin A injections, including 3 muscular weakness complications. The global success rate of the first injection was significantly lower in patients with poor compliance (34.4% vs 86.9%, OR 0.08, p <0.001). On multivariate analysis poor compliance was associated with a lower global success rate (OR 0.13, p <0.001). Female gender (OR 3.53, p = 0.01) and patient age (OR 39.9, p <0.001) were predictors of global success., Conclusions: Intradetrusor botulinum toxin A injections were effective in adult patients with spina bifida who had detrusor overactivity. In contrast, effectiveness was much lower in adult patients with spina bifida who had poor bladder compliance. The other predictors of global success were female gender and older age., (Copyright © 2018 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Objectives: To describe the technique and report our first experience of robotic-assisted renal transplantation (RART) with more than one year follow up., Patients and Methods: In our center the first case of RART was realized in October 2013 with a cadaveric graft. We used the combined extra- and intraperitoneal robot assisted laparoscopic route with extraperitoneal positioning of the graft and intraperitoneal transplantation. The patient was placed in the supine position with arms along the body; the robot came from the right inferior part of the patient. Access to the retroperitoneal space was obtained using an Alexis trocar that permitted the insertion of the kidney with ice without losing the pneumoperitoneum. Ports included a 12-mm camera port (placed under the ombilicus), two 8-mm robotic ports (placed 6cms laterally from the previous port) and a 12-mm assistant port (placed between the upper port and the ombilic). All the pre-, per- and postoperative data were prospectively included in a database. We report the results of the initial experience of RART, performed with more than one year follow-up., Results: This technique is the first described using the retroperitoneal approach that is the routine approach for conventional open renal transplantation. This approach permitted to perform excellent arterial, veinous and ureteral anastomosis. Eight cases of RART were conducted between October 2013 and November 2015 (five men and three women). The average age was 58 years (range 39-75years). The average body mass index was 28 (range 22-38). Five patients had history of abdominal surgery and were dialyzed for 30 months on average (range 3-63months). Three left and five right cadavers kidneys were transplanted in the right iliac fossa. The mean graft size was 109mm (range 90-130). The mean length of the incision for insertion of the graft was 60 mms (40-100mms). Mean warm ischemia time was 63minutes (range 46-84). The total operative time was 200minutes (149-245). No patient was transfused during surgery and two were transfused postoperatively. Median length of hospital stay was 14 days (range 10-30 days). Only one patient needed postoperative morphine, the pain visual analogic scale 12hours postoperatively was 2 (0-5). Mean serum creatinine at seven days, at three months and at one year was 400 (98-639micromol/L), 151 (80-235micromol/L) and 129 (86-194micromol/L) respectively. At one year follow-up, no patient had a wound infection or incisional hernia. One patient was re-operated for ureteral anastomosis stricture., Conclusion: The retroperitoneal approach for RART permits the kidney to be cooled and a direct access to the iliac vessels and bladder. This initial series with more than a year of post-monitoring RART shows promising results despite some initial technical difficulties. The procedure can still be improved and hoped to see an improvement in the results. A comparison to the results of the conventional route is necessary before diffusing the robot-assisted technique., Level of Proof: 3., (Copyright © 2017 Elsevier Masson SAS. All rights reserved.)

Objectives: Renal transplantation is performed only in university hospital centres, in accredited transplanting centres. The aim of this study is to analyse the learning curve of this operation and its impact on the graft survival., Patients-Methods: Monocentric retrospective study in which 3 groups have been defined: Juniors 1, Juniors 2 and Seniors corresponding respectively to the first thirty transplantations and to the last thirty transplantations of 5 clinical leaders, and 30 transplantation graft of referent seniors. Data have been registered in a database. Operation times, lukewarm ischemic times and postoperative complications have been compared within the 3 groups., Results: A clear difference of operation time has been noted within the 3 groups with an average time of 202 minutes for Juniors 1, 173 minutes for Juniors 2 and 140 minutes for Seniors (P<0.0001). Likewise, concerning lukewarm ischemic time and vascular anastomosis time respectively with an average time of 72, 59 and 40 min (P<0.0001). Vascular complications occurred in 20% of cases in Juniors 1, 44.3% of cases in Juniors 2 and 17% of cases in Seniors (P=0.65). There were no significant differences of survival without urinary complications: 20% of complications for Juniors 1, 10% for Juniors 2 and 17% for Seniors (P=0.63). Similarly results have been obtained with analysing complications following Clavien's order., Conclusion: This study reveals that renal transplantations operated by young surgeons require longer operation and lukeward ischemic time but without significant repercussions on the surgical complication rate and the global survival. This stresses on the importance of surgical training during medicine internship., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

Objective: To describe the quality of glycemic control in patients in intensive care units (ICUs) treated with an intravenous (IV) insulin infusion at a teaching hospital., Method: This retrospective study included patients admitted to the ICU and treated with an IV insulin infusion for at least 12 h between August 1 and November 30, 2011. Medical charts were reviewed. The primary quality indicator for glycemic control was the mean percent of blood glucose values per patient in the 6.1 to 8 mmol/L target range., Results: A total of 351 patients were included; 61.5% of subjects had no known diabetes. Admissions were mainly for surgery (61.3%). The mean Acute Physiology and Chronic Health Evaluation (APACHE) II score was 16.8±7.3. The mean percent of blood glucose values per patient in the 6.1 to 8 mmol/L range was 35% for all subjects and 26.2% for patients with diabetes. If a target of 6.1 to 10 mmol/L was considered, those values became 63% and 54.6%. At least 1 episode of hyperglycemia (>10 mmol/L), hypoglycemia (<4 mmol/L) or severe hypoglycemia (<2.2 mmol/L) was documented in 68%, 9% and 1% of subjects, respectively. Glycemic variability (SD) was 1.9 mmol/L, and the median hyperglycemic index was 0.77 (interquartile [IQ]: 0.24 to 1.63)., Conclusion: The quality of glycemic control in patients in the ICU at our hospital needs to be improved. A new computerized IV insulin protocol is currently being tested., (Copyright © 2014 Canadian Diabetes Association. Published by Elsevier Inc. All rights reserved.)

While dysglycemia (hyperglycemia, hypoglycemia and glucose variability) is clearly associated with increased mortality in critically ill patients, target range of blood glucose control remains controversial. Standardized insulin infusion protocols constitute the basis of treatment of these patients. The choice of protocol and its implementation is a great challenge. In this article, we review the published data to help define the essential elements that compose a good protocol and apply the right conditions to make it safe and effective., (Copyright © 2014 Canadian Diabetes Association.

The identification of migration routes, wintering grounds and stopover sites are crucial issues for the understanding of the Palearctic-African bird migration system as well as for the development of relevant conservation strategies for trans-Saharan migrants. Using miniaturized light-level geolocators we report a comprehensive and detailed year round track of a granivorous trans-Saharan migrant, the European Turtle Dove (Streptopelia turtur). From five recovered loggers, our data provide new insights on migratory journeys and winter destinations of Turtle Doves originating from a breeding population in Western France. Data confirm that Turtle Doves wintered in West Africa. The main wintering area encompassed Western Mali, the Inner Delta Niger and the Malian/Mauritanian border. Some individuals also extended their wintering ranges over North Guinea, North-West of Burkina Faso and the Ivory-Coast. Our results reveal that all individuals did not spend the winter period at a single location; some of them experienced a clear eastward shift of several hundred kilometres. We also found evidence for a loop migration pattern, with a post-breeding migration flyway lying west of the spring route. Finally, we found that on their way back to breeding grounds Turtle Doves needed to refuel after crossing the Sahara desert. Contrary to previous suggestions, our data reveal that birds used stopover sites for several weeks, presumably in Morocco and North Algeria. This later finding is a crucial issue for future conservation strategies because environmental conditions on these staging areas might play a pivotal role in population dynamics of this declining species.

Unlabelled: What's known on the subject? and What does the study add? Patients with end-stage renal disease (ESRD) have an increased risk of developing RCC in their native kidneys. The prevalence of RCC is 3-4% in cases of ESRD in dialyzed and/or transplanted patients, which corresponds to a rate 100-times higher than that in the general population. This is the first study, to our knowledge, comparing the characteristics of kidney cancer in the ESRD population according to their dialysis or transplantation status at the time of diagnosis. The differences in stage and survival we observed may be due to differences in surveillance strategies between transplanted and not transplanted patients, nevertheless, the differences in pathological subtypes suggest they could also be due to differences in the tumorigenesis process., Objective: • To compare clinical, pathological and outcome features of renal cell carcinomas (RCCs) arising in patients with chronic renal failure (CRF) with or without renal transplantation., Patients and Methods: • In all, 24 French University Departments of Urology and Kidney Transplantation participated in this retrospective study comparing RCCs arising in patients with CRF according to their dialysis or transplantation status at the time of diagnosis. • Information about age, sex, symptoms, duration of CRF, mode and duration of dialysis, renal transplantation, tumour staging and grading, histological subtype and outcome were recorded in a unique database. • Qualitative and quantitative variables were compared by using chi-square and Student statistical analysis. Survival was assessed by Kaplan-Meier and Cox methods., Results: • Data on 303 RCC cases diagnosed between 1985 and 2009 were identified in 206 men (76.3%) and 64 women (23.7%). • Transplanted and not transplanted patients accounted for 213 (70.3%) and 90 cases (29.7%), respectively. • In transplant recipients, RCC was diagnosed at a younger age [mean (sd) 53 (11) vs 61 (14) years, P < 0.001), the mean tumour size was smaller [3.4 (2.3) vs 4.2 (3.1) cm, P= 0.02), pT1a stage (75 vs 60%, P= 0.009) and papillary histological subtype (44 vs 22%, P < 0.001) were more frequent than in their dialysis-only counterparts. • Nodal (1 vs 6%, P= 0.03) and distant metastases rates (0 vs 5%, P < 0.001) were significantly increased in patients who had not had a transplant. However, Fürhman grading, symptoms, tumour multifocality or bilaterality, presence of acquired cystic kidney disease, were not significantly different between the groups. • Estimated 5-year survival rates were 97% and 77% for transplanted and not transplanted patients, respectively (P < 0.001). In univariate analysis, presence of symptoms (P= 0.008), poor performance status (P= 0.04), large tumour size, advanced TNM stage (P < 0.001), high Führman grade (P= 0.005) and absence of transplantation (P < 0.001) were all adverse prognostic factors. In multivariate analysis, only T stage remained an independent predictor for cancer-related death (P < 0.001)., Conclusion: • RCC arising in native kidneys of transplant patients seems to exhibit many favourable clinical, pathological and outcome features compared with those diagnosed in dialysis-only patients. Further research is needed to determine whether it is due to particular molecular pathways or to biases in relation to mode of diagnosis., (© 2012 BJU INTERNATIONAL.)

De novo tumors in renal allografts are rare and their prevalence is underestimated. We therefore analyzed renal cell carcinomas arising in renal allografts through a retrospective French renal transplant cohort. We performed a retrospective, multicentric survey by sending questionnaires to all French kidney transplantation centers. All graft tumors diagnosed after transplantation were considered as de novo tumors. Thirty-two centers participated in this study. Seventy-nine tumors were identified among 41 806 recipients (Incidence 0.19%). Patients were 54 men and 25 women with a mean age of 47 years old at the time of diagnosis. Mean tumor size was 27.8 mm. Seventy-four (93.6%), 53 (67%) and 44 tumors (55.6%) were organ confined (T1-2), low grade (G1-2) and papillary carcinomas, respectively. Four patients died of renal cell carcinomas (5%). The mean time lapse between transplantation and RCC diagnosis was 131.7 months. Thirty-five patients underwent conservative surgery by partial nephrectomy (n = 35, 44.3%) or radiofrequency (n = 5; 6.3%). The estimated 5 years cancer specific survival rate was 94%. Most of these tumors were small and incidental. Most tumors were papillary carcinoma, low stage and low grade carcinomas. Conservative treatment has been preferred each time it was feasible in order to avoid a return to dialysis., (© Copyright 2012 The American Society of Transplantation and the American Society of Transplant Surgeons.)

Introduction: Transplantation Committee of the French Association of Urology (CTAFU) conducted a review of the complication of kidney transplantation in obese recipients., Material and Methods: A bibliographic research in French and English using Medline with the keywords "obesity", "body mass index", "kidney transplantation", "graft function", "survival", "wound complications", "graft rejection" and "graft survival" was performed. We limited the review for the last fifteen years because of the change in immunosuppressive treatment area. Only studies with more than 20 obese patients were selected., Results: Wound or infectious postoperative complications and delayed graft function are more frequent in obese patients than in non-obese recipients. Similarly, transplant survival at 5 years is lower in obese patients. On the other hand, patient survival and acute rejection are the same between the two groups if recipient selection is carefully made, particularly with regard to heart complication., Conclusion: Kidney transplantation in obese patients is not an easy surgery with known complication. Obese patients will take time before transplantation to explain all the risk and a regular heart follow-up is crucial if we don't want to reduce patient survival. But obese survival is better if we proceed to kidney transplantation than if they stay on dialysis, arguing for a non-exclusion of the waiting list. So there is the need for a national study concerning obese patients on waiting list to enact future guidelines., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

Background: Kidneys with multiple arteries are often transplanted. However, the long-term outcome of such kidneys recovered exclusively from deceased donors is not clear., Objective: To determine whether use of renal grafts with multiple arteries affects long-term graft survival and function., Methods: The outcomes of 259 consecutive kidney transplants between 1996 and 2000 were retrospectively reviewed. Patients were divided into 2 groups, multiple renal artery graft recipients (n = 70) and single renal artery graft recipients (n = 189). Short-term complications and long-term outcomes (survival rates, blood pressure after transplant, creatinine clearance, and proteinuria levels at 1, 3, 5, and 7 years after transplant) were compared between the 2 groups., Results: Early vascular complications were more common (P = .02) in multiple artery graft recipients (18.6%) than in single artery graft recipients (7.9%), mainly because of occlusion of a polar artery in grafts with multiple renal arteries (7.1%). Urologic complications were no more frequent in one group than in the other (5.7% vs 5.3%; P = .89). The 2 groups did not differ significantly (P = .33) in long-term graft survival, with a median follow-up of 9.05 years (range, 0.1-12.7 years). Mean (SD) for creatinine clearance (59.4 [22.6] vs 55.9 [20.3] mL/min; P = .47), proteinuria (0.77 [2.1] vs 0.4 [0.8] g/24 h; P = .19), and systolic blood pressure (133.6 [14.5] vs 133.7 [17.5] mm Hg; P = .85) did not differ significantly between the 2 groups 7 years after transplant., Conclusions: Kidney transplant with grafts containing multiple renal arteries rather than grafts with a single renal artery does not significantly influence patient and graft outcomes.

Background: Patients with end-stage renal disease (ESRD) are at risk of developing renal tumours., Objective: Compare clinical, pathologic, and outcome features of renal cell carcinomas (RCCs) in ESRD patients and in patients from the general population., Design, Setting, and Participants: Twenty-four French university departments of urology participated in this retrospective study., Intervention: All patients were treated according to current European Association of Urology guidelines., Measurements: Age, sex, symptoms, tumour staging and grading, histologic subtype, and outcome were recorded in a unique database. Categoric and continuous variables were compared by using chi-square and student statistical analyses. Cancer-specific survival (CSS) was assessed by Kaplan-Meier and Cox methods., Results and Limitations: The study included 1250 RCC patients: 303 with ESRD and 947 from the general population. In the ESRD patients, age at diagnosis was younger (55 ± 12 yr vs 62 ± 12 yr); mean tumour size was smaller (3.7 ± 2.6 cm vs 7.3 ± 3.8 cm); asymptomatic (87% vs 44%), low-grade (68% vs 42%), and papillary tumours were more frequent (37% vs 7%); and poor performance status (PS; 24% vs 37%) and advanced T categories (≥ 3) were more rare (10% vs 42%). Consistently, nodal invasion (3% vs 12%) and distant metastases (2% vs 15%) occurred less frequently in ESRD patients. After a median follow-up of 33 mo (range: 1-299 mo), 13 ESRD patients (4.3%), and 261 general population patients (27.6%) had died from cancer. In univariate analysis, histologic subtype, symptoms at diagnosis, poor PS, advanced TNM stage, high Fuhrman grade, large tumour size, and non-ESRD diagnosis context were adverse predictors for survival. However, only PS, TNM stage, and Fuhrman grade remained independent CSS predictors in multivariate analysis. The limitation of this study is related to the retrospective design., Conclusions: RCC arising in native kidneys of ESRD patients seems to exhibit many favourable clinical, pathologic, and outcome features compared with those diagnosed in patients from the general population., (Copyright © 2011 European Association of Urology.

Aim: Laparoscopic pelvic lymphadenectomy in localized prostatic cancer is performed since the 1990s, lessens the postoperative complications and respects carcinologic's principles (No. lymph nodes removed and lymph nodes metastasis). In order to verify that these objectives are achieved, we compared our results of pelvic lymphadenectomy by laparotomy and by laparoscopy for the past 12 years., Patients and Methods: Between January 1997 and June 2008, 36 (23.8%) patients underwent open pelvic lymphadenectomy and 76.16% (115 cases) laparoscopic pelvic lymphadenectomy. We did a retrospective and comparative analysis of data including the preoperative characteristics, per- and postoperative complication as well pathologic results., Results: Preoperative data were comparable between both groups. The comparison of the peroperative data showed an increased bleeding volume in the open group (105.6±420.9mL; 12.1±96.1mL: P=0.001) and longer operative time in the laparoscopic group (103.7±83.9min; 132.8±40.9min: P=0.006). Postoperative complications were similar. Pathologic results showed a significantly more important number of lymph nodes removed in the open group (7.2±3.5; 5.7±3.2: P=0.022), but the positive rate similar in both groups (13.9%; 22.6%: P=0.258). In order to remove "the learning curve effect", we compared 36 open pelvic lymphadenectomy to the last 36 laparoscopic pelvic lymphadenectomy. In the laparoscopic group the patients showed an upper Gleason score (6.3±1.1; 7±1: P=0.005); but there was no difference for the operative time, number of lymph nodes removed and the complications rates., Conclusions: After training, laparoscopic pelvic lymphadenectomy was similar to open pelvic lymphadenectomy., (Copyright © 2010 Elsevier Masson SAS.

Objectives: To identify the risk factors for ureteral stenosis after renal transplantation and to evaluate their impact on both graft and patient survival., Patients and Methods: This retrospective study included 789 kidney transplants among 782 patients performed at our institution between 1995 and 2007. The parameters studied included the characteristics of the donor, recipient and transplant, the surgical variables, the elements of the monitoring process and a graft and patient survival., Results: The ureteral stenosis rate after renal transplantation was found to be 6.5%, and the ureterovesical junction was the most common location (68%). A univariate analysis showed that this complication was significantly associated with a higher donor age (P=0.01), abnormal graft revascularisation (P=0.032) and DGF (Delay Graft Function) (P=0.05). In multivariate analysis, only donor age (P=0.001) and abnormal graft revascularisation (P=0.035) were independent risk factors for ureteral stenosis after renal transplantation. When ureteral stenosis was treated, an analysis of the survival curves according to the Kaplan-Meier method did not reveal significant differences either in graft survival (P=0.518) or overall survival of the patients (P=0.614) as compared to the control group., Conclusions: In the present study, donor age and abnormal graft revascularisation were independent risk factors for ureteral stenosis after renal transplantation. This result is a strong argument for an ischemic component in the genesis of ureteral stenosis after renal transplantation, which should help to identify patients at risk., (Copyright © 2010 Elsevier Masson SAS.

Objective: Radial-cephalic fistulas (RCFs) perianastomotic stenoses (PASs) are on and around the fistula anastomosis. This group of lesions encompasses juxta-anastomotic stenosis (stenosis located on the venous side within 3 cm away from the anastomosis), anastomotic, and arterial stenosis. The purpose of our study was to assess the postintervention primary patency and assisted postintervention primary patency (APP) rates for surgery and angioplasty when treating these stenoses. The secondary endpoint was to identify factors that might influence the procedure's patency rates., Materials and Methods: This retrospective study included 73 consecutive patients treated for lack of maturation PASs between January 1999 and December 2005 in two interventional centers. Patients' mean age was 65 years old. Stenoses were treated by surgery (n = 21) or percutaneous transluminal angioplasty (PTA; n = 52). Surgery meant creation of a new anastomosis excluding the area of stenosis. Preoperative characteristics including the patient's age, gender, comorbidities, stenosis location, and length were not statistically different between the two groups. The mean follow-up was 39 months for PTA and 49 months for surgery., Results: Anatomical and clinical success rates were 86% and 90% for surgery, and 75% and 92% for PTA. At 1 year, the primary patency rates were 71 ± 10% for surgery and 41 ± 6% for PTA, respectively (P < .02). There was no significant difference between the two groups with respect to assisted primary patency (95% vs 92%). In the PTA group, stenosis location at the anastomosis itself was a risk factor of early recurrence (P = .047). The complication rate was similar between surgery and PTA., Conclusion: Our results suggest that the treatment of anastomotic stenoses should be surgical rather than endovascular. Angioplasty and surgery have shown similar results when used to treat other perianastomotic stenoses, but repeat procedures were more frequent with angioplasty., (Copyright © 2011 Society for Vascular Surgery.

The objective of this study was to assess the value of a urine bacterial culture performed before prostate biopsy. We performed a prospective study on 353 patients who underwent prostate biopsy. All patients had a urine bacterial culture performed before biopsy. We compared the outcomes of patients with bacteriuria (left untreated) with those of patients without bacteriuria. Of the 353 men, 12 had a pre-biopsy-positive bacterial culture and underwent prostate biopsy without any infectious complication. Fifteen patients with a negative pre-biopsy culture developed a post-biopsy-positive bacterial culture, but remained asymptomatic without any treatment. Only four men from the group without pre-biopsy bacteriuria developed an infectious complication, requiring 3 weeks of antibiotic therapy. The complication rates were similar for both groups. Our results suggest that routine urine bacterial culture before prostate biopsy is not useful when antibiotic prophylaxis and enema are performed. We do, however, suggest performing a urine bacterial culture before prostate biopsy for patients with a previous history of urinary tract infections.

Background: Delayed maturation of radial-cephalic fistulas can be due to lesions of the radial artery that are amenable to percutaneous dilation., Methods: Over a period of 7 years, 74 consecutive patients underwent angiography of an immature fistula that showed either stenosis or an insufficient enlargement of the radial artery that was treated by percutaneous dilation. Success, complications and secondary interventions were recorded according to consensus definitions. Patency following angioplasty was estimated with the Kaplan-Meier technique., Results: The mean patient age was 70 years, 44% were women, 69% had diabetes, 23% were smokers, 76% had hypertension, 64% had coronary disease and 46% had peripheral artery occlusive disease. Concomitant venous stenosis was diagnosed in 53% of patients. Arterial stenosis was >5 cm long in 53 cases. Technical success was achieved in 73/74 cases following angioplasty. All but two fistulas were then successfully used for dialysis. Dilation-induced rupture occurred in 13 cases (17%) but required only two stent placements. Five cases (7%) of hand ischaemia within 1 month of dilation were treated successfully by ligation of the distal artery. Primary patency rates at 12 and 24 months were significantly better for pure arterial lesions, with 65% and 61% compared to 42% and 35% in cases of concomitant venous stenosis (P < 0.04). The secondary patency rates were 96% and 94% at 1 and 2 years, respectively., Conclusion: Dilation of the radial artery yields higher patency rates than for veins. Surgeons might therefore be less demanding about the initial quality of the radial artery prior to creation of radial-cephalic fistulas.

Objective: Perianastomotic stenoses (PAS) complicating native arteriovenous fistulas (AVF) of the forearm can be treated by angioplasty or surgery. The objective of this study was to report primary patency (PP) and primary assisted patency (PAP) rates of surgery and angioplasty of these stenoses. The secondary objective was to identify factors influencing the patency rates of these reoperations., Material and Methods: Seventy-three patients with a mean age, 65 years were treated for PAS between January 1999 and December 2005 in two centres (Tours and Le Mans), which were retrospectively included. PAS were treated by surgery (n=21) or angioplasty (n=52). The two groups were comparable. The mean follow-up was 39 months for the angioplasty group and 49 months for the surgery group (p=0.088)., Results: The PP rate was 71+/-10% for surgery and 41+/-6% for angioplasty (p<0.0175). The PAP rate was not significantly different (p=0.462) between angioplasty (92+/-4%) and surgery (95+/-4%). In the endovascular group, the site of stenosis on the anastomosis was a risk factor for early recurrence (95% CI between 0.006 and 0.392; p=0.047)., Conclusion: These results suggest that anastomotic stenoses should be treated surgically rather than by angioplasty. Angioplasty and surgery give identical patency rates in other types of perianastomotic stenoses at the cost of a higher reoperation rate for angioplasty.

Autosomal dominant polycystic kidney disease (ADPKD) which accounts for 15% of all renal transplantations emerges as the third cause of kidney transplantation in France. In addition to routine evaluation before transplantation, the ADPKD patient requires special assessment of three aspects: should potential kidney complications (recurrent upper tract infection or haemorrhage) or kidney size assessed by computed tomography require nephrectomy prior to transplantation? Is it advisable to detect intracranial aneurysm (ICA) in patients with a relative having experienced ruptured ICA? When transplantation from a living relative is considered, the existence of ADPKD in the donor should be formally ruled out by imaging or genetic studies. The risk of recurrence of ADPKD post-transplantation does not exist. Nevertheless other complications may occur. Thus, an increased incidence of colonic perforation has been reported. In addition, as compared to non-ADPKD patients, an increased risk for both skin cancer and new-onset post-transplant diabetes mellitus has been reported recently after kidney transplantation. Finally, because these patients suffer from an inherited syndrome, physicians should carefully consider the personal and familial history before and after transplantation in order to respond to fatalism in some cases, or to attenuate excessive enthusiasm in the others. Altogether, it apears that a specific approach is needed for ADPKD patients when considering renal transplantation.

Study Objective: The objective of this prospective study was to describe the nature of the lesions observed during brain-dead cadavre donor kidney harvesting in France and to identify the risk factors for these lesions., Material and Methods: A questionnaire elaborated by the AFU Transplantation Committee concerning the quality of kidneys harvested from cadavre donors was sent to all centres performing renal transplantation in France in 2000. This prospective study was conducted over a period of 1 year and concerned the overall multi-organ harvesting procedure based on all data concerning the renal parenchyma, arteriovenous and ureteric characteristics, and the outcome of the transplants., Results: Twelve centres completed the survey, allowing analysis of the data of 201 donor kidneys. 91% of harvesting surgeons were urologists. Various incidents were reported during 11% of harvesting procedures, but 1/3 of the abnormalities were not recorded by the harvesting surgeon. Isolated kidney harvesting was found to be a risk factor (20% vs 8.6%). The rate of parenchymal abnormalities was 50%, 2/3 of which were related to inadequate removal of perirenal fat. Atheroma was a risk factor for arterial lesions during harvesting (21% vs 6.50). Venous abnormalities were detected in 9% of cases: 89% of them were due to the harvesting procedure and 59% of them were not identified by the harvesting surgeon. The fact of not being a transplant surgeon was a risk factor for venous lesions (21.9% vs 6.5%). 4% of ureteric lesions were observed with no consequence on graft outcome., Conclusion: Adequate removal of perirenal fat before conditioning is not acquired. Isolated kidney harvesting and atheroma were risk factors for parenchymal and arterial lesions, respectively. Venous harvesting anomalies were more frequent among non-transplant surgeons.

Objectives: To compare pain during prostate biopsy performed in two different positions., Methods: We carried out a prospective, randomized study to compare the pain experienced during biopsy in two different positions: lithotomy (group 1) and lateral (group 2). Pain was evaluated using a visual analog scale (VAS)., Results: 70 patients were randomized to the two positions for biopsy. The median number of samples taken was the same for both groups (n = 10). The median VAS rating after biopsy was 30 in group 1 and 45 in group 2. 96.6% of the men in group 1 were prepared to undergo a repeat examination according to the same modalities, against only 86.7% in group 2. Only 14.3% of the men in group 1 would have preferred more analgesic against 37.1% in group 2. Pain after biopsy was less in group 1. The men with prostate adenocarcinoma tolerated biopsies better than the others., Conclusion: Our results suggest that the lithotomy position induced less pain and less post-biopsy hematuria than did the lateral position during prostate biopsy. Men with prostate adenocarcinoma tolerated the procedures better.

Chicken ovalbumin upstream promoter transcription factors (COUP-TF)-II (NR2F2) and EAR-2 (NR2F6) are structurally related orphan members of the nuclear receptors superfamily. There are growing evidences that these factors play important roles during processes of differentiation and proliferation of several tissues. To better understand their role in the differentiated adult rat pituitary gland, we cloned COUP-TFII and EAR-2 cDNAs from an anterior pituitary cDNA library. Subsequently, we raised and characterized specific antibodies to the N-terminal domain of both nuclear receptors. We next examined their cellular and subcellular distribution in the pituitary gland and determined their regulation during pregnancy. COUP-TFII and EAR-2 pituitary genes display, respectively, 90 and 100% homologies with their human and mouse homologues. Cellular expression of both nuclear receptors was mainly detected in the lactotropes of male and female rats, with a prominent distribution in the nuclear compartment for EAR-2, and interestingly both proteins were significantly upregulated in pituitaries of pregnant vs. cycling female rats. Thus, our results have characterized cloning of rat pituitary COUP-TFII and EAR-2 genes, demonstrated that they are both specifically expressed in lactotropes, and strongly suggested that they may play an important role in modulating prolactin (PRL) gene expression during pregnancy.

Most seminal vesicle cysts have an embryological origin and are often associated with homolateral renal agenesis. The diagnosis of seminal vesicle cyst has been greatly improved by progress in medical imaging, particularly ultrasound, which reveals a retrovesical cystic image and homolateral renal agenesis. Transperineal or laparoscopic vesiculectomy is technically difficult and is associated with high morbidity. The authors report a case of laparoscopic vesiculectomy with an uneventful postoperative course.

Objective: Urinary incontinence is a very common disease among women but only few studies have been published in young adult and middle-aged population. We studied urinary incontinence prevalence and risk factors in this young and middle-aged population., Material and Methods: We studied during the year 1998 the prevalence of global incontinence and stress, urge and mixed urinary incontinence in 1700 women working in a French academic hospital (n = 2800). Women received the questionnaire at the same time than their convocation for their yearly visit in occupational medicine. Usual risk factors of constitutional events (increasing âge, obesity defined by a Body Mass Index > or = 25); obstetric events (pregnancy, previous caesarean delivery, previous vaginal delivery, post-partum incontinence) and gynaecological event (hysterectomy) were evaluated., Results: 177 women (mean âge 40.0 years) returned the questionnaire. 467 women (27.5% 95% CI = 25.4-29.7) reported urinary incontinence, 210 (12.4% 95% CI = 10.8-14.0) stress urinary incontinence, 28 (1.6% 95% CI = 1.1-2.4) urge urinary incontinence and 229 (13.5% 995% CI = 11.9-15.2) mixed urinary incontinence. 38 women (8.1%) suffered from frequent urinary leakage corresponding to 1 (0.5%), 4 (14.3%) and 33 (14.4%) stress, urge and mixed urinary incontinence. The prevalence of urinary incontinence increased significantly with âge > or = 40 years (RR = 2.16 95% CI = 1.86-2.57) pregnancy (RR = 2.22 95% CI = 1.71-2.87), previous vaginal delivery (RR = 2.15 95% CI = 1.72-2.69), post-partum incontinence (RR = 2.57 95% CI = 2.22-2.97, hysterectomy (RR = 1.52 95% CI = 1.11-2.08). Obesity (RR = 1.14 95% CI = 0.99-1.32) and previous caesarean delivery (RR = 2.15 95% CI = 1.72-2.69) did not increase the risk of urinary incontinence. The risk factors for stress urinary incontinence were âge > or = 40 years (RR = 2.18 95% CI = 1.66-2.87), pregnancy (RR = 2.36 95% CI = 1.55-3.58), previous vaginal delivery (RR = 2.47 95% CI = 1.70-3.59), post-partum incontinence (RR = 2.78 95% CI = 2.14-3.61) and hysterectomy (RR = 2.83 95% CI = 1.93-4.15). No relationship was found between stress urinary incontinence and obesity (RR = 1.25 95% CI = 0.96-1.64) and previous caesarean delivery (RR = 1.02 95% CI = 0.45-2.32)., Conclusion: A high prevalence of urinary incontinence was observed among young adult and middle-aged female hospital workers with an easy access to medical resources. Gynaecological and obstetric event (pregnancy particularly previous vaginal delivery and hysterectomy) were the most prominent risk factors, especially for stress urinary incontinence.

Objective To assess the prevalence of and risk factors for urinary incontinence (UI) in young and middle-aged women. Subjects and methods During 1998 the prevalence of overall, stress, urge and mixed UI was assessed in women working in a French academic hospital. Women (2800) received a questionnaire at the same time as their yearly interview with a staff physician in occupational medicine. The usual risk factors for constitutional events, i.e. increasing age, obesity (defined as a body mass index of > or = 25), obstetric events (pregnancy, previous Caesarean delivery, previous vaginal delivery, postpartum incontinence) and gynaecological events (hysterectomy) were evaluated. Results Of the 1700 women (mean age 40.0 years) who returned the questionnaire, 467 (27.5%, 95% confidence interval, CI, 25.4-29.7) reported UI, comprising 210 (12.4%, 10.8-14.0) with stress UI, 28 (1.6%, 1.1-2.4) with urge UI and 229 (13.5%, 11.9-15.2) with mixed UI. Thirty-eight women (8.1%) had frequent urinary leakage, comprising one (0.5%), four (14.3%) and 33 (14.4%) with stress, urge and mixed UI. The prevalence of UI increased significantly with age > or = 40 years, with a relative risk (95% CI) of 2.16 (1.86-2.57), and with pregnancy (2.22, 1.71-2.87), previous vaginal delivery (2.15, 1.72-2.69), postpartum incontinence (2.57, 2.22-2.97), and hysterectomy (1.52, 1.11-2.08). Obesity (1.14, 0.99-1.32) and previous Caesarean delivery (2.15, 1.72-2.69) did not significantly increase the risk of UI. The risk factors for stress UI were age > or = 40 years, pregnancy, previous vaginal delivery, postpartum incontinence and hysterectomy, but there was no relationship between stress UI and obesity or previous Caesarean delivery. Conclusion There was a high prevalence of UI among young adult and middle-aged women hospital workers who had easy access to medical resources. Gynaecological and obstetric events (pregnancy, particularly previous vaginal delivery and hysterectomy) were the most prominent risk factors, especially for stress UI.

Cortisol secretion in adrenal Cushing's syndrome can be regulated by the aberrant adrenal expression of receptors for gastric inhibitory polypeptide, vasopressin, catecholamines, LH/human CG (LH/hCG), or serotonin. Four patients with incidentally discovered bilateral macronodular adrenal hyperplasia without clinical Cushing's syndrome were evaluated for the possible presence of aberrant adrenocortical hormone receptors. Urinary free cortisol levels were within normal limits, but plasma cortisol levels were slightly elevated at nighttime and suppressed incompletely after dexamethasone administration. Plasma ACTH was partially suppressed basally but increased after administration of ovine CRH. A 51-yr-old woman had ACTH-independent increases of plasma cortisol after 10 IU AVP im (292%), 100 microg GnRH iv (184%), or 10 mg cisapride orally (310%); cortisol also increased after administration of NaCl (3%), hCG, human LH, and metoclopramide. In a 61-yr-old man, cortisol was increased by AVP (349%), GnRH (155%), hCG (252%), and metoclopramide (191%). Another 53-yr-old male increased plasma cortisol after AVP (171%) and cisapride (142%). Cortisol secretion was also stimulated by vasopressin in a 54-yr-old female. This study demonstrates that subclinical secretion of cortisol can be regulated via the aberrant function of at least V1-vasopressin, LH/hCG, or 5-HT4 receptors in incidentally identified bilateral macronodular adrenal hyperplasia.

Objectives: To report and prevent a serious complication of tension-free vaginal tape (TVT) procedure., Case Report: One day after a TVT procedure, an emergency CT scan showed adhesion of intestinal loops with a pneumoperitoneum. The patient had previously had intra- and retroperitoneal surgery with a sacral cervicopexy and a Burch colposuspension., Conclusion: In such a case of previous surgery, a CT scan may be useful before a TVT procedure.

The autoregulation of prolactin (PRL) secretion in the rat has been demonstrated at both the hypothalamus and the pituitary levels. Studies on the direct negative feedback effect of PRL in the lactotrophs have concentrated on the acute effect on PRL secretion which does not involve change in PRL synthesis. In this study, we have developed a cotransfection assay in somatolactotrophs where we examine the effect of PRL on the transcription of its own gene. We found that oPRL, at physiological concentrations, exerts a strong and specific inhibition of the rPRL gene transcription in PRL-deficient GC cells. This effect is mediated by both the intermediate and the long forms of PRL receptor. The inhibition was also reproduced in GH3 cells, which secretes PRL, by adding exogenous oPRL in the presence of anti-rat PRL antiserum to neutralize endogenous rPRL. Cellular specificity was demonstrated by testing this regulation in non-pituitary cell types where no modulation of the PRL promoter reporter gene could be elicited by PRL, even with cotransfection with the Pit-1 expression vector. Finally, deletions of the rPRL promoter indicate that the full inhibitory effect of PRL requires the same regulatory domains (proximal and distal) that have been described for the other PRL gene regulators. These results strongly suggest the existence of the extra-short loop regulation of the rat PRL at the transcriptional level.

Nuclear orphan receptors are known to be important mediators of neurogenesis, but the target genes of these transcription factors in the vertebrate nervous system remain largely undefined. We have previously shown that a 500-base pair fragment in the first intron of the GRIK5 gene, which encodes the kainate-preferring glutamate receptor subunit KA2, down-regulates gene expression. In our present studies, mutation of an 11-base pair element within this fragment resulted in a loss of nuclear protein binding and reverses negative regulation by the intron. Using yeast one-hybrid screening, we have identified intron-binding proteins from rat brain as COUP-TFI, EAR2, and NURR1. Gel shift studies with postnatal day 2 rat brain extract indicate the presence of COUP-TFs, EAR2, and NURR1 in the DNA-protein complex. Competition assays with GRIK5-binding site mutations show that the recombinant clones exhibit differential binding characteristics and suggest that the DNA-protein complex from postnatal day 2 rat brain may consist primarily of EAR2. The DNA binding activity was also observed to be enriched in rat neural tissue and developmentally regulated. Co-transfection assays showed that recombinant nuclear orphan receptors function as transcriptional repressors in both CV1 cells and rat CG4 oligodendrocyte cells. Direct interaction of the orphan receptors with and relief of repression by TFIIB indicate likely role(s) in active and/or transrepression. Our findings are thus consistent with the notion that multiple nuclear orphan receptors can regulate the transcription of a widely expressed neurotransmitter receptor gene by binding a common element in an intron and directly modulating the activity of the transcription machinery.

Gastric inhibitory polypeptide (GIP)-dependent Cushing's syndrome has been reported to occur either in unilateral adrenal adenoma or in bilateral macronodular adrenal hyperplasia. A 33-yr-old woman with Cushing's syndrome was found to have two 2.5- to 3-cm nodules in the right adrenal on computed tomography scan; the left adrenal appeared normal except for the presence of a small 0.8 x 0.6-cm nodule. Uptake of iodocholesterol was limited to the right adrenal. Plasma morning cortisol was 279 nmol/L fasting and 991 nmol/L postprandially, and ACTH remained suppressed. Plasma cortisol increased after oral glucose (202%) or a lipid-rich meal (183%), but not after a protein-rich meal (95%) or iv glucose (93%); the response to oral glucose was blunted by pretreatment with 100 microg octreotide, sc. Plasma cortisol and GIP levels were positively correlated (r = 0.95; P = 0.0001); cortisol was stimulated by the administration of human GIP iv (225%), but not by GLP-1, insulin, TRH, GnRH, glucagon, arginine vasopressin, upright posture, or cisapride orally. A right adrenalectomy was performed; GIP receptor messenger ribonucleic acid was overexpressed in both adrenal nodules and in the adjacent cortex. Histopathology revealed diffuse macronodular adrenal hyperplasia without internodular atrophy. Three months after surgery, fasting plasma ACTH and cortisol were suppressed, but cortisol increased 3.6-fold after oral glucose, whereas ACTH remained suppressed; this was inhibited by octreotide pretreatment, suggesting that cortisol secretion by the left adrenal is also GIP dependent. We conclude that GIP-dependent nodular hyperplasia can progress in an asynchronous manner and that GIPR overexpression is an early event in this syndrome.

Growth hormone (GH) and prolactin (PRL) exert their regulatory functions in the mammary gland by acting on specific receptors. Using isotopic in situ hybridization and immunohistochemistry, we have localized the expression of hGH receptor (hGHR) and hPRL receptor (hPRLR) in a panel of human breast disorders. Surgical specimens from adult females included normal breast, inflammatory lesions (mastitis) benign proliferative breast disease (fibroadenoma, papilloma, adenosis, epitheliosis), intraductal carcinoma or lobular carcinoma in situ, and invasive ductal, lobular or medullary carcinoma. Cases of male breast enlargement (gynecomastia) were also studied. In situ hybridization analysis demonstrated the co-expression of hGHR and hPRLR mRNA in all samples tested. Epithelial cells of both normal and tumor tissues were labelled. Quantitative estimation of receptor mRNA levels was regionally measured in areas corresponding to tumor cells and adipose cells from the same section. It demonstrated large individual variation and no correlation emerged according to the histological type of lesion. Receptor immunoreactivity was detected both in the cytoplasm and nuclei or in the cytoplasm alone. Scattered stromal cells were found positive in some cases, but the labeling intensity was always weaker than for neoplastic epithelial cells. Our results demonstrate the expression of the hGHR and hPRLR genes and their translation in epithelial cells of normal, proliferative and neoplastic lesions of the breast. They also demonstrate that stromal components express GHR and PRLR genes. Thus the putative role of hGH or hPRL in the progression of proliferative mammary disorders is not due to grossly altered levels of receptor expression.

We have previously demonstrated that the oxytocin (OT) gene is expressed in the rat uterine epithelium and that its expression is upregulated in vivo and in vitro by estrogen. This hormonal regulation is mediated by a hormone response element (HRE) located in the OT gene promoter. Here we show that the same OT-HRE is also capable of interacting with two novel members of the orphan nuclear receptor family, rat COUP-TFII and Ear-2, and that this interaction antagonizes the estrogenic induction of the OT promoter. By Northern blot analysis and immunocytochemistry, using specific cDNA probes and antibodies, respectively, we demonstrate furthermore that both orphan receptors are expressed in uterine epithelial cells. Therefore, the present findings indicate that uterine OT gene expression is under stimulatory as well as inhibitory influences which are both mediated by the same HRE. More detailed analysis of the sequences necessary for estrogen receptor action and for orphan receptor action, using site-directed mutagenesis, revealed that the specific recognition sequences are overlapping but distinct: whereas the (imperfect) palindromic structure of the HRE constitutes the estrogen response element (ERE), orphan receptor action relies on an underlying direct TGACC repeat which forms part of the OT-HRE structure and overlaps with the estrogen response element.

Time- and sex-specific summer survival of roe deer fawns was estimated using capture-mark-recapture methods in two enclosed populations living in contrasting conditions. The population of Trois Fontaines (eastern France) was roughly constant in size throughout the study period, while in Chizé (western France), the population experienced frequent summer droughts and numbers decreased continuously during the study. Early survival of fawns was low and highly variable over the years at both Chizé and Trois Fontaines, and demonstrated marked variations between cohorts that need to be taken into account when modelling roe deer population dynamics. In Trois Fontaines, fawn survival was positively correlated with early body growth and total rainfall in May and June. In Chizé, fawn survival decreased with increasing density and tended to increase with increasing rainfall in May and June and adult female body mass. These factors explained more than 75% of the variability in early survival observed in both populations. Variation between cohorts had different consequences for the two populations. At Trois Fontaines, cohort variation was limited to a numerical effect on early survival. However at Chizé, cohort variation was long-lasting and affected the phenotypic quality of survivors at later ages, and thereby future survival and breeding abilities (both numerical and quality effects). Male and female fawns had similar survival over their first summer in both populations. This result contrasts with the lower survival of young males often observed in ungulates. Two ultimate causes can be proposed to account for the low and variable survival of roe deer fawns over the first summer: the high energy expenditures incurred by does during each breeding attempt and/or the low absolute body size of newborn roe deer fawns.

Retinoic acid (RA), an important regulator of cell differentiation, is biosynthesized from retinol via retinal by a two-step oxidation process. We previously reported the purification and partial amino acid (aa) sequence of a rat kidney aldehyde dehydrogenase (ALDH) isozyme that catalyzed the oxidation of 9-cis and all-trans retinal to corresponding RA with high efficiency [Labrecque et al. Biochem. J. 305 (1995) 681-684]. A rat kidney cDNA library was screened using a 291-bp PCR product generated from total kidney RNA using a pair of oligodeoxyribonucleotide primers matched with the aa sequence. The full-length rat kidney ALDH cDNA contains a 2315-bp (501 aa) open reading frame (ORF). The aa sequence of rat kidney ALDH is 89, 96 and 87% identical to that of the rat cytosolic ALDH, the mouse cytosolic ALDH and human cytosolic ALDH, respectively. Northern blot and RT-PCR-mediated analysis demonstrated that rat kidney ALDH is strongly expressed in kidney, lung, testis, intestine, stomach and trachea, but weakly in the liver.

Objectives: To calculate the incidence of surgical treatment of benign prostatic hyperplasia (BPH) in two French departments, Indre-et-Loire and C her, in order to deduce the incidence in France., Methods: All patients operated for BPH by transurethral resection or transvesical prostatectomy were counted prospectively over a 6-month period by all surgeons of the Indre-et-Loire and Cher departments. Collection of case files was complete and based on BPH resection specimens sent to pathology. 506 patients were included in this survey., Results: The mean age of the patients was 71.8 years. 78% of patients were operated by a private urologist, and 93% by a specialist urologist. The mean postoperative stay was 7.1 days and varied according to the patient's age, the weight of the prostate and the site of the operation (university hospital, private establishment and general hospital). This study allowed calculation of the annual incidence of surgery for BPH in these 2 departments: 822/100,000 men over the age of 50 years. The maximal incidence was observed during the 7th decade of life: 1,742/100,000. In our study, private urologists operated 76 patients for BPH per year., Conclusion: Extrapolation of these results to the French population indicates an annual incidence of surgery for benign prostatic hyperplasia in France of 776/100,000 men over the age of 50 years. On the basis of this incidence, an estimated 55,000 to 65,000 men are operated for BPH per year in France.
