Objectives: Analyze the oncologic and functional outcomes in patients affected by low risk prostate cancer underwent prostate cryotherapy. Materiasl and methods: It’s a prospective tricentric study of 434 patients treated with prostate cryoablation for low risk prostate cancer. By low risk we refer to the D'Amico’s risk classification. Two cycles of freezing/thawing are run for each patient following the technique described by Onik. Results: For the 434 patients, the median age was 66 years with a standard deviation of ± 6.68, the average PSA was 6.17 ng/d/L, the median 5.55 with a standard deviation of ± 2.13, the mean prostate volume was 35.59 cc, the median 34.00 cc, with a standard deviation of ± 7.89. Biochemical failure occurred in 67 patients (15.4%). Pre-operative erectile function in men was distributed as follows: severe in 95 patients (19.2%), moderate in 95 (19.2%), medium-moderate in 180 (36.4%), mild in 92 (18.6%), with no dysfunction in 32 (6.5%) patients. Post-operative erectile function, measured 1 month after cryotherapy, was distributed as follows: severe in 321 (65%) patients, moderate in 69 (14%), medium-moderate in 79 (16%), mild in 23 (4.7%), and no dysfunction in only 2 patients (0.4%). Post-operative erectile function after 3 months was distributed as follows: severe in 233 (47.2%) patients, moderate in 66 (13.4%), medium-moderate in 122 (24.7%), mild in 65 (13.2%), and no dysfunction in 8 patients (1.6%). Urinary incontinence was present in 21 patients (4.8%) after 3 months while it dropped to 13 patients (2.9%) after 6 months. Conclusions: Cryotherapy in the treatment of prostate cancer remains a viable alternative. The availability of new cryoprobes and the use of new diagnostic means such as fusion magnetic resonance will make this more precise and more effective method.

Objective To evaluate our experience in patients undergoing hybrid transvaginal natural orifices transluminal endoscopic surgery (NOTES) nephrectomy and evaluate the sexual functions in the postoperative period. Materials and Methods Prospective data of 71 patients with renal tumors who underwent hybrid NOTES radical nephrectomy in three different centers were collected from March 2010 to October 2015. Patient and surgical characteristics were recorded. Sexual function was evaluated using the Female Sexual Function Index questionnaire the day prior to the operation and 3 months after. Results The mean age, tumor size, and operation duration were 66.16 ± 11.21, 8.51 ± 3.31 cm, and 119.94 ± 21.38 minutes, respectively. Five patients were immediately reoperated due to bleeding from uterine veins. The complication risk increases significantly with increasing tumor size. Among the whole cohort, even the Female Sexual Function Index score differences are small; there is a statistically significant decrease in the postoperative period in all domains except sexual satisfaction. In fact, the patients reported unaltered sexual function after surgery and satisfaction with the result when asked directly. In subgroup analyses, in nulliparous patients (n = 60), arousal, sexual desire, orgasm, and satisfaction domains have no significant differences in pre- and postoperative periods. Conclusions Hybrid NOTES nephrectomy is a feasible, safe operation that can be performed for large renal tumors. Due to incisions in the vaginal wall for specimen retrieval, sexual function can be altered in the postoperative period. So patient selection, preoperative evaluation, and close follow-up are mandatory. With this in mind, we strongly support the use of hybrid transvaginal NOTES nephrectomy for large renal tumors especially in nulliparous patients.

To assess the performance of prostate health index (PHI) and prostate cancer antigen 3 (PCA3) when added to the PRIAS or Epstein criteria in predicting the presence of pathologically insignificant prostate cancer (IPCa) in patients who underwent radical prostatectomy (RP) but eligible for active surveillance (AS). An observational retrospective study was performed in 188 PCa patients treated with laparoscopic or robot-assisted RP but eligible for AS according to Epstein or PRIAS criteria. Blood and urinary specimens were collected before initial prostate biopsy for PHI and PCA3 measurements. Multivariate logistic regression analyses and decision curve analysis were carried out to identify predictors of IPCa using the updated ERSPC definition. At the multivariate analyses, the inclusion of both PCA3 and PHI significantly increased the accuracy of the Epstein multivariate model in predicting IPCa with an increase of 17 % (AUC = 0.77) and of 32 % (AUC = 0.92), respectively. The inclusion of both PCA3 and PHI also increased the predictive accuracy of the PRIAS multivariate model with an increase of 29 % (AUC = 0.87) and of 39 % (AUC = 0.97), respectively. DCA revealed that the multivariable models with the addition of PHI or PCA3 showed a greater net benefit and performed better than the reference models. In a direct comparison, PHI outperformed PCA3 performance resulting in higher net benefit. In a same cohort of patients eligible for AS, the addition of PHI and PCA3 to Epstein or PRIAS models improved their prognostic performance. PHI resulted in greater net benefit in predicting IPCa compared to PCA3.

Objectives To explore whether serum and urinary advanced glycation end-products (AGEs) are related to urinary symptoms and bladder dysfunctions in diabetic patients. Methods Forty-seven patients with type 2 Diabetes mellitus (T2DM) and lower urinary tract symptoms (LUTS) were enrolled. LUTS evaluation was performed by IPSS (International Prostatic Symptoms Score), QoL (quality of life), OAB (overactive bladder). ICI-SF (International Consultation on Incontinence – short form) quaestionneires; ultrasound examination, evaluation of postvoid residual (PVR), uroflowmetry, cystometry with pressure-flow study (PFS) were performed to detect bladder dysfunctions. Serum and urinary AGEs were quantified by ELISA method. Results Patients were divided into four subgroups: (i) normal-detrusor-contractility + normal- detrusor-activity (1 ♂ [4.8%] and 4 ♀ [21%]), (ii) impaired-detrusor-contractility + normal-detrusor- activity (4 ♂ [19.1%] and 0 ♀), (iii) normal-detrusor-contractility + detrusor-overactivity (1 ♂ [4.8%] and 6 ♀ [31.6%]), (iv) impaired-detrusor-contractility + detrusor-overactivity (15 ♂ [71.4%] and 9 ♀ [47.4%]). Serum AGEs were 12.2 ± 5.5 in men and 10.4 ± 5.6 in women; urinary AGEs were 1.5 ± 1.1 in men and 2.5 ± 1.6 in women. Serum AGEs exhibited a positive correlation with IPSS (P

Objectives: Locally advanced prostate cancer may cause several complications such as haematuria, bladder outlet obstruction, and renal failure due to the ureteral obstruction. Various treatments have been suggested, including radiotherapy, antifibrinolytics, bladder irrigation with alum solution, transurethral surgery and angioembolization, none of which have proven effectiveness. In the last years cryoablation has become a valid therapeutic option for prostate cancer. In our experience we used this ‘new’ technique as haemostatic therapy. Methods: We selected four patients with gross haematuria affected by locally advanced hormone refractory prostate cancer, who had already been treated with primary radiotherapy. We used third-generation cryotherapy: under ultrasonographic guidance, we inserted six cryoprobes, two in each of the vascular pedicles reaching at least −60°C, and three thermometers. We then induced two freeze–thaw cycles. Results: After the operation the haematuria stopped in all patients and at 9-month follow up we observed a mean of four red cells (range three to five) in the urinary sediment with no evidence of bacteriuria. Prostate volume, prostate-specific antigen and postmicturition residue were significantly reduced. Qmax improved significantly too. Conclusion: Our experience has given us good results with minimal intra- and postoperative complications. We think that haemostatic cryotherapy as a palliative approach for locally advanced prostate cancer could represent a valid treatment option and more consideration could be given to its use.

Transrectal Ultrasound (TRUS) guided prostate biopsy is regarded as the gold standard for prostate cancer diagnosis. The majority of patients perceive TRUS-guided prostate biopsy as a physically and psychologically traumatic experience. We aimed to compare in this paper the efficacy of three different anesthesia techniques to control the pain during the procedure. Materials and methods: 150 patients who underwent transrectal ultrasound (TRUS) guided prostate biopsy were randomly divided into three groups. Group A included 50 patients who received one hour before the procedure a mixture of 2.5% lidocaine and 2.5% prilocaine, Group B: 50 patients who received intrarectal local anesthetic administration (lidocaine 5 ml 10%) and lidocaine local spray 15 % and Group C included 50 patients who received periprostatic block anesthesia (lidocaine 10 ml 10%). Visual analogue scale (VAS) of patients in different groups was evaluated at the end of the biopsy and 30 minutes after the procedure. Results: The VAS of patients in Group A was 1.32 ± 0.65 (VAS I) and 2.47 ± 0.80 (VAS II). In group B the VAS of patients was 1.09 ± 0.47 (VAS I) and 1.65 ± 0.61 (VAS II). In group C the VAS of patients was 2.63 ± 0.78 (VAS I) and 1.70 ± 0.85 (VAS II). There was no statistically significant difference in term of VAS I between group A and B. A statistically significant difference was determined in terms of VAS II between group A and B. There was no statistically significant difference in term of VAS between group B and C. Conclusions: The most effective of the three methods for pain control we used was intrarectal local anesthetic administration and lidocaine local spray 15% that enables an ideal patient comfort.

Introduction: To evaluate the intermediate-term outcomes of thulium vapoenucleation of the prostate (ThuVEP) and thulium vaporesection of the prostate (ThuVaRP) in patients with benign prostate obstruction (BPO). Materials and Methods: A bicentric retrospective matched-paired comparison of patients treated by ThuVEP (n = 80) or ThuVaRP (n = 80) was performed. The patients were preoperatively assessed with International Prostate Symptom Score (IPSS), quality of life (QoL), post-void residual urine (PVR), maximum urinary flow rate (Qmax), prostatespecific antigen (PSA) and re-evaluated at 12- and 24-month follow-up. Results: Median prostate volume was 65 mL and not different between the groups. The immediate re-operation rate was significantly different between ThuVEP and ThuVaRP (5 vs. 0%, p ≤ 0.0434). IPSS, QoL, Qmax and PVR had improved significantly compared to preoperative assessment in both groups at 12- and 24-month follow-up (p ≤ 0.001). Median Qmax (18.2 vs. 21.0 mL/s) and PVR (29.4 vs. 0 mL) were significantly different between ThuVEP and ThuVaRP at 24-month follow-up (p ≤ 0.001), while IPSS and QoL showed no differences between the groups. However, the PSA reduction was significantly higher after ThuVEP compared to ThuVaRP (78.93 vs. 23.39%, p ≤ 0.006) at 24-month follow-up. Conclusions: ThuVEP and ThuVaRP are safe and efficacious procedures for patients with BPO. Although the peri-operative re-intervention rates were lower after ThuVaRP, the low PSA reduction rate after ThuVaRP at 24-month follow-up favours the ThuVEP procedure.

Introduction The advancements in telemedicine provide the possibility to send photos of hematuria cases to professionals for further evaluation. We aimed to evaluate the inter-rater reliability of WhatsApp use in the evaluation of hematuria. Materials and methods Between December 2014 and April 2016, 212 patients were evaluated prospectively for hematuria by 2 groups of urologists; Group A: in direct contact with patients for evaluation; Group B: “blind” urologist who had no access to the patients’ data but received pictures via WhatsApp. Two photos of voided urine in a sterile container were taken and sent using WhatsApp. The opinions of Group A and B about the grade of hematuria were evaluated. Shapiro-Wilk test and Fleiss’ kappa statistics were used for statistical analyses. Results The median age of patients was 71 (min 22, max 96). The Group A urologists were in accordance in 96.22% of cases. Group B urologists had common opinions in 99.5% (n = 203) and there was almost perfect agreement between 2 groups (λ = 0.992). The number of common opinions among “blind” urologists is more than the number of common opinions among the consultants. When further classification is performed as serious and non-serious hematuria, the rate of misdiagnosing serious cases is approximately 6.5–7%. However, using WhatsApp, the urologists can differentiate normal urine and any form of hematuria with 100% accuracy. Conclusion It is possible to evaluate hematuria remotely and also reduce unnecessary costs of services for hematuria of mild clinical significance by using telemedicine. WhatsApp can provide valuable aid to tertiary hospitals where the urologist is not always present as well as in rural areas.

Recent evidence has shown that positive results may be observed for fluorodeoxyglucose-positron emission tomography (FDG-PET) in undifferentiated, biologically aggressive and metastatic tumors. The present study describes a case series of six patients with normal prostate-specific antigen (PSA) serum levels who underwent FDG-PET due to other causes. Positive PET results were observed at the prostate and the patients were subsequently diagnosed with high-risk prostate cancer. Clinical, anamnestic, laboratory and instrumental data were collected from six asymptomatic patients with total serum PSA levels of

Interstitial cystitis/painful bladder syndrome (IC/PBS) is a chronic pain syndrome and a chronic inflammatory condition prevalent in women that leads to urgency, sleep disruption, nocturia and pain in the pelvic area, to the detriment of the sufferer’s quality of life. The aim of this review is to highlight the newest diagnostic strategies and potential therapeutic techniques. A comprehensive literature review was performed on MEDLINE, PubMed, and Cochrane databases gathering all literature about “Interstitial cystitis” and “Painful Bladder Syndrome”. Visual analogue scales, epidemiological strategies, pain questionnaires and similar techniques were not included in this literature survey. The etiology, exact diagnosis and epidemiology of IC/PBS are still not clearly understood. To date, its prevalence is estimated to be in the range of 45 per 100,000 women and 8 per 100,000 men, whereas joint prevalence in both sexes is 10.6 cases per 100,000. There are no “gold standards” in the diagnosis or detection of IC/PBS, therefore, several etiological theories were investigated, such as permeability, glycosaminoglycans, mast cell, infection and neuroendocrine theory to find new diagnostic strategies and potential biomarkers. Due to the fact that this disease is of an intricate nature, and that many of its symptoms overlap with other concomitant diseases, it could be suggested to classify the patients with emphasis on the phenotype, as well as their symptom clusters, to tailor the diagnostic and management choices according to the observed biomarkers.

Purpose Thulium vaporesection of the prostate (ThuVARP) is a new and safe approach for patients receiving anticoagulant therapy in whom transurethral resection of the prostate (TURP) may possess a high bleeding risk. We aimed to demonstrate the efficacy and safety of ThuVARP in patients receiving oral antiplatelet/anticoagulant (OAP/OAC) therapy. Materials and methods A total of 103 patients who underwent ThuVARP between 2011 and 2013 were enrolled in the study. Patients were divided into 2 groups. Group A consisted of 47 patients who underwent low molecular weight heparin (LMWH) bridging and group B consisted of 56 patients who were operated on while receiving OAP/OAC therapy. Results The drop in hemoglobin levels in the pre- and postoperative periods was significantly higher in group A than in group B. When subgroups were analyzed, the mean drop in hemoglobin was significantly lower in the warfarin and ticlopidine subgroups of group B than in group A. International Prostate Symptom Scores were significantly lower 3, 12, 18, and 24 months after surgery in group A than in group B. Quality of life scores, maximal flow rate values, and postmicturition residual urine volumes (mL) were similar between the 2 groups. A total of 38 and 41 patients in groups A and B, respectively, had no complications. Conclusions Our study showed the safety profile of continuing different OAP/OAC therapies in terms of bleeding problems in patients undergoing ThuVARP. We strongly recommend abandoning LMWH bridging and maintaining the OAP/OAC regimen patients are already receiving.

To evaluate the precision of the centrality index (CI) measurement on three-dimensional (3D) volume rendering technique (VRT) images in patients with renal masses, compared to its standard measurement on axial images.Sixty-five patients with renal lesions underwent contrast-enhanced multidetector (MD) computed tomography (CT) for preoperative imaging. Two readers calculated the CI on two-dimensional axial images and on VRT images, measuring it in the plane that the tumour and centre of the kidney were lying in. Correlation and agreement of interobserver measurements and inter-method results were calculated using intraclass correlation (ICC) coefficients and the Bland-Altman method. Time saving was also calculated.The correlation coefficients were r=0.99 (p0.05) and r=0.99 (p0.05) for both the CI on axial and VRT images, with an ICC of 0.99, and 0.99, respectively. Correlation between the two methods of measuring the CI on VRT and axial CT images was r=0.99 (p0.05). The two methods showed a mean difference of -0.03 (SD 0.13). Mean time saving per each examination with VRT was 45.5%.The present study showed that VRT and axial images produce almost identical values of CI, with the advantages of greater ease of execution and a time saving of almost 50% for 3D VRT images. In addition, VRT provides an integrated perspective that can better assist surgeons in clinical decision making and in operative planning, suggesting this technique as a possible standard method for CI measurement.

Background Pacemakers in upper urinary tract (UUT) are still under study. Aim We reviewed the role of some cells that seem to be involved in the propulsion of urinary bolus from UUT to the bladder. Materials & Methods We focuses on evaluating studies on the mechanisms by which the UUT propels urine to the bladder via pacemaker cells. Results Electric active pacemaker cells generate pyeloureteric autorhythmicity driving adjacent smooth muscle cells (SMCs); it emphasizes the role of the interstitial cells of Cajal-like cells (ICC-LCs) localized in the UUT. Interstitial cells of Cajal (ICCs) are now thought to cooperate in conducting and amplifying pacemaker activity in the UUT. These cells produce electrical slow-wave potentials and determine the propagation of peristaltic activity. Identification of ICC-LCs is facilitated by use of c-kit antibodies. Contraction waves arising from the UUT and the propagation of these waves may require the direct involvement of ICC-LCs, as c-kit immunoreactivity appears developmentally at the same time as coordinated unidirectional peristaltic contraction. ICC-LCs observed in the UUT have morphological features similar to those of c-kitpositive ICCs in the gastrointestinal tract. In addition to gastrointestinal motility, ICCs may also play a significant role in the propagation, coordination, and modulation of ureteropelvic peristalsis. Discussion Alterations in ICC-LCs are closely associated with a variety of motility disorders and many congenital urological diseases of the UUT such as primary obstructive megaureter, congenital ureteropelvic junction obstruction, and vesicoureteral reflux. Conclusion These observations open the way for further investigations of this cell type. Neurourol. Urodynam. 32: 349–353, 2013. © 2012 Wiley Periodicals, Inc.

Objective To study the effect of PDRN on angiogenesis in a model of varicocele in rats. Design After the creation of experimental varicocele, rats were randomized to one of the four treatments: vehicle, PDRN, DMPX, and PDRN plus DMPX. Twenty-one days after randomization, all animals were euthanized and the left testis was harvested. Setting Academic hospital. Animal(s) Male Sprague-Dawley rats were used. Intervention(s) A clamp was passed behind the left renal vein distally to the spermatic vein insertion. A silk ligature was placed around the left renal vein at this site and was tied over the top of a probe. The latter was then withdrawn and the vein was allowed to expand. In shams, a suture was placed but it was not tied. Main Outcome Measure(s) To assess testicular microvascular density using CD34 immunostaining. Result(s) Microvascular density in the varicocele plus PDRN group was significantly higher than in other groups. Conclusion(s) PDRN could represent a novel therapeutic strategy for varicocele treatment in subfertile patients, improving the innate pathophysiologic mechanism of neoangiogenesis, through compensatory oxygen and metabolite supply to tubular and extratubular testicular compartments.

Ureteropelvic junction obstruction is one of the most common causes of hydronephrosis in children. A malfunction of smooth muscle cells is believed to be the underlying mechanism causing obstruction. We investigated the expression of some integrins, talin and β-dystroglycan, considered the main compound of smooth muscle cell cytoskeleton, and active caspase 3 at the level of the ureteropelvic junction obstruction.Specimens were obtained at pyeloplasty in 12 children with ureteropelvic junction obstruction. Six control specimens were obtained during organ explantation. Specimens were divided into renal pelvis, ureteropelvic junction and ureter below the obstruction. Western blot analysis of active caspase 3, and immunofluorescence and polymerase chain reaction analysis were performed for α7A, β1A, α7B and β1D integrins, talin and β-dystroglycan.Talin and β-dystroglycan were slightly impaired in ureteropelvic junction obstruction, while α7B and β1D integrins were severely reduced, and α7A, β1A and active caspase 3 were significantly enhanced compared to controls.We demonstrated activation of apoptosis and a critical alteration of cytoskeleton that might explain the altered function and the increased apoptosis in smooth muscle cells in ureteropelvic junction obstruction. The delayed rearrangement of the cytoskeleton of smooth muscle cells in ureteropelvic junction obstruction might be linked to a postnatal splicing from α7A and β1A to α7B and β1D integrins, respectively. This relationship could explain the common clinical scenario of spontaneous improvement of hydronephrosis in children with suspected ureteropelvic junction obstruction.

UNLABELLED Study Type - Therapy (case series). LEVEL OF EVIDENCE 4. What's known on the subject? and What does the study add? Bilateral nerve-sparing radical prostatectomy still represents an issue for urologists as the indications to perform it depend oft from the personal clinical experience. Moreover, until now data concerning bilateral and unilateral laparoscopic nerve-sparing radical prostatectomy have been limited. This study states that bilateral laparoscopic intrafascial nerve-sparing technique results in superior functional outcomes when compared with unilateral nsLRP and it suggests to prefer a bilateral nerve-sparing technique in younger patients with low-risk, organ-confined prostate cancer. OBJECTIVE To evaluate the surgical and functional outcomes in bilateral and unilateral nerve-sparing laparoscopic radical prostatectomy (nsLRP). PATIENTS AND METHODS Between January 2005 and May 2009, 457 nsLRP were performed at our clinic. In all, 250 patients underwent a bilateral nsLRP and 207 patients underwent an unilateral nsLRP. One surgeon performed all the operations. All patients presented at biopsy a localized prostate cancer. Demographic data and perioperative and postoperative measurements and outcomes were compared. RESULTS The operative times for bilateral nsLRP and unilateral nsLRP were 165 ± 45 min and 130 ± 25 min, respectively. The mean intra-operative blood loss was 450 ± 300 mL and 270 ± 160 mL in the bilateral and unilateral nsLRP groups with a transfusion rate of 3% and 1%, respectively (P = 0.013). Conversion to open surgery was never deemed necessary. Postoperatively, the mean Gleason Score after nsLRP and distribution of tumour stages was similar in the two groups, and the frequency of positive margins in both groups did not present any statistically significant difference. At 12 months, a complete continence was reported in 97% of patients who underwent a bilateral nsLRP and in 88% of patients of the unilateral nsLRP group. At that time, 69% in the bilateral nsLRP and 43% in the unilateral nsLRP groups reported the ability to engage in sexual intercourse. CONCLUSION The bilateral laparoscopic intrafascial nerve-sparing technique results in superior functional outcomes with regard to urinary continence and sexual potency, when compared with unilateral nsLRP, reporting similar oncological outcomes.

Objectives: To evaluate the efficacy and safety of Serenoa repens + selenium and lycopene (Profluss®) versus S. repens alone for the treatment of category IIIa chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Patients and Methods: 102 patients with IIIa CP/CPPS were enrolled and randomized into two groups each to receive Profluss or S. repens alone for 8 weeks. Evaluation was based on results of the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), IPSS, maximum peak flow rate (MPFR), and PSA measurements at baseline and at weeks 4, 8 and 8 after the end of treatment. The primary endpoint was a >50% reduction in NIH-CPSI score. Secondary endpoints evaluated were MPFR, IPSS, PSA and white blood cell count. Results: No patients withdrew from the study. The mean NIH-CPSI score decreased significantly (p < 0.001) in both groups; we observed a decrease in the total score from 27.45 to 13.27 in group 1 (–51.64%) and from 27.76 to 20.62 in group 2 (–26.06%). IPSS improved significantly (p < 0.001) in both arms, but more in group 1. PSA and white blood cell count decreased significantly (p < 0.007) only in group 1. The MPFR improved more in group 1 (p < 0.005). Conclusion: Profluss is a triple therapy that is safe and well tolerated. It ameliorates symptoms associated with IIIa CP/CPPS.

Microcystic urothelial carcinoma is a rare variant of transitional cell carcinoma with an indefinite prognostic significance. Herein, we report for the first time the acquisition of microcystic histology in the penile metastasis of a high-grade urothelial carcinoma of the urinary bladder. The patient died of disseminated disease six months later. The immunohistochemical evaluation of mucin expression in the primitive and metastatic tumor suggests that the microcystic histotype may descend from the primitive urothelial carcinoma through a process of dedifferentiation and subsequent redifferentiation. In conclusion, the acquisition of microcystic histology seems to be associated with an aggressive clinical course of the urothelial carcinoma, as already suggested by other authors. Future studies investigating mucin expression in microcystic urothelial carcinoma may help to define the histogenesis of this tumor.

Background: Fournier’s gangrene (FG) is a very aggressive necrotizing fasciitis involving subcutaneous fat and skin of scrotal and perineal regions. Vacuum-assisted closure (VAC) is a well-known method used to treat complex wounds. The authors for the first time enhance a multimodal strategy to treat the FG using VAC, reducing the number of surgical debridements, allowing a one-step surgical reconstruction with locoregional fasciocutaneous flap. Methods: Six patients with the diagnosis of FG were reviewed retrospectively at our institution. All patients were affected by very extensive FG. The FG Severity Index (FGSI) was used to evaluate the prognosis of the case at admission. Following the acute phase (24–48 h), VAC was used to achieve wound cleaning and prepare the area to a single-stage reconstruction with superomedial thigh flap. Hyperbaric oxygen therapy was also used before final reconstruction. Results: The average FGSI was 10.5, ranging from 8 to 12. All patients survived and were completely healed at the mean follow-up time of 9 months (range 3–30 months). Conclusions: VAC therapy is effective to clean and prepare the wounds, cutting off the fasciitis process and reducing the hospital stay and patient discomfort. Multidisciplinary treatment is mandatory during this devastating infection.

Spontaneous subcapsular renal hematoma is a rare condition in clinical practice. It is caused by renal cysts, benign and malignant renal tumors, vascular lesions, and antiplatelet or anticoagulant therapy. In this paper we report an unusual case of rupture of a renal cyst of a 66-year-old male patient during an aortic and iliac endovascular procedure for a massive calcified atheroma above the iliac bifurcation. We suspected that the bolus of high weight molecular heparin given during the procedure caused the rupture of the cyst. According to the literature, this is the first case of renal cyst rupture during an endovascular aortic procedure after administering a high weight molecular heparin bolus.

To evaluate the medium-term effect of epidural analgesia (EA) on the possible onset of postpartum urinary incontinence (PUI).We performed a single-centre, retrospective case-control study. At 8-week postpartum, we recruited a cohort of women who had term singleton pregnancy and foetus in cephalic presentation, and divided in six groups: (1) vaginal delivery without episiotomy, without EA; (2) vaginal delivery without episiotomy, with EA; (3) vaginal delivery with episiotomy, without EA; (4) vaginal delivery with episiotomy, with EA; (5) emergency caesarean section without previous EA during labour and (6) emergency caesarean section with previous EA during labour. For each woman, we recorded age, Body Mass Index (BMI) and the result of the following questionnaire for urinary incontinence: International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), Incontinence Impact Questionnaire-7 (IIQ-7) and Urogenital Distress Inventory-6 (UDI-6). Subsequently, we compared group 1 versus group 2, group 3 versus group 4 and group 5 versus group 6.We did not evidence any significant difference for age, BMI and incontinence scores between groups 1 and 2, 3 and 4, and 5 and 6.EA did not affect the onset of PUI in medium-term, regardless the mode of delivery.

Introduction: To evaluate the short-term results of thulium vaporesection of the prostate (ThuVEP) and thulium vapoenucleation of the prostate (ThuVARP) in patients with benign prostatic obstruction on oral anticoagulants (OA). Methods: A 3-centre retrospective matched-paired comparison of patients treated by ThuVEP (n = 26) or ThuVARP (n = 26) was performed. Thirty-four patients were on aspirin/ticlopidin, 7 on clopidogrel or clopidogrel and aspirin, and 11 on phenprocoumon at the time of surgery. Results: Haemoglobin decrease was higher after ThuVEP compared to ThuVARP (1.5 vs. 0.3 g/dl, p < 0.001). The rate of postoperative blood transfusions (3.9 vs. 0%), clot retention (3.9 vs. 0%), and re-operation (7.7 vs. 0%) was not different between ThuVEP and ThuVARP (p = 0.274). Catheterization time was shorter for ThuVARP (1 vs. 2 days, p < 0.01). Qmax was significantly higher after ThuVEP at 6-month follow-up (31 vs. 21.5 ml/s, p < 0.001), while improvements in International Prostate Symptom Score, quality of life, and post-voiding residual urine showed no differences between the groups. Urethral or bladder neck strictures did not occur during the 6-month follow-up in both groups. Conclusions: ThuVEP and ThuVARP are safe and efficacious procedures in patients on OA. Although patients assigned to ThuVEP had higher Qmax at 6-month follow-up, ThuVARP resulted in similar functional outcomes.

Background: Bladder cancer is the fifth most common cancer among men and the seventh among women. At diagnosis, at least 25% of bladder cancer tumors are locally or systemically advanced. Systemic chemotherapy is the only current modality for advanced or metastatic transitional cell carcinoma of the bladder. Recently, a phase III randomized study has demonstrated that the regimen with gemcitabine (GMC) and cisplatin (CDDP) had a survival advantage similar to the standard M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin), with a better safety profile. Aim: It was the aim of this study to evaluate the tumor response rate, the median time to progression, the median survival and toxicity in a 21-day schedule with GMC and CDDP in patients with advanced/metastatic bladder cancer. Patients and Methods: From September 1998 to December 2000, 27 patients with advanced/metastatic transitional cell carcinoma were enrolled. All patients received 1,200 mg/m2 GMC administered as a 30-min intravenous infusion on days 1 and 8, and 75 mg/m2 CDDP as a 1-hour infusion on day 2. Cycles were repeated every 21 days. The patients had a median age of 59.8 years (range 39–75) and an Eastern Cooperative Oncology Group performance status of 0–2. Results: Twenty-five patients were valuable for toxic effects, length of survival and tumor response. The statistical analysis was performed in May 2004. Mean and median follow-up were 20.23 and 13.2 months (range 2–68), respectively. The overall remission rate (complete response + partial response) was 48% (95% CI 28.4–67.6%). The median time to progression was 9 months (range 2–56). The median duration of survival for all patients was 13.2 months (range 2–68+), with 1-year and 23-month survival rates of 60 and 20%, respectively. There was no grade 4 toxicity or treatment-related death. Grade 3 anemia was observed in 4 patients (16%) and grade 3 thrombocytopenia occurred in 6 patients (24%). No grade 3–4 nausea/vomiting or neutropenia was observed. Conclusion: GMC and CDDP is an active schedule with a good safety profile in a 21-day regimen. It may be a valid alternative to the standard 28-day regimen due to its high tumor response and survival with a low incidence of toxicity, especially in pretreated and metastatic patients.

As a preliminary approach to define the object of larger case-control studies, the distribution of potential risk factors coming from environmental pollution among patients affected by superficial bladder cancer (TCCB) has been analyzed. Material e Methods. The analysis included only patients affected by medium risk superficial TCCB. Forty Italian urological centres joined the study. Detailed information about age, sex, residency, employment, active and passive cigarette smoking, water resource, hair-dye use were centralized. All patients underwent TUR and early intravesical chemotherapy. The distribution of the above mentioned environmental factors was related to tumor characteristics such as multiplicity and previous natural history. Results. Until today 474 patients have been recruited, 182 (38.4%) with primary tumors and 293 (61.8%) with multiple lesions. Over 80% of the patients lived in urban areas, 20% were employed in industry at risk for bladder cancer and 8% used hair dye. Forty percent of the patients were smokers, with a median smoking period of 30 years. Bottled water was the only water resource in 42% of cases. At multivariate statistical analysis a significant correlation between tumor multiplicity and employment in industry (p

The diagnosis of prostate carcinoma has been monitored in Sicily and Calabria for one year. Material e Methods Twenty-seven urological centres of Sicily and Calabria joined the study. Detailed informations about age, familiarity, PSA, Gleason score and TNM stage at diagnosis were centralized between november 2001 and november 2002. Results 721 patients have been recruited. The median age was 73 years. More than 80% of the patients were older than 65 years. Median PSA was 14 ng/ml. The clinical stage at diagnosis was T1c in 33% of patients and 67% had an organ confined prostate cancer (T1-T2). Familiarity was detected in 8% of cases. Age and PSA at diagnosis in these patients were similar to those of the remaining population. However, only 18% of them had a T1 tumor, emphasizing the delay in diagnosis in these patients. Although only 10% of the patients shows at diagnosis a metastatic tumor, 29% only are fit for radical prostatectomy in according to age, PSA and stage.

Objectives: To determine the endocrine effects, efficacy and tolerability of the 3-month formulation of goserelin acetate (‘Zoladex’ 10.8-mg depot; ‘Zoladex’ is a trade mark of the AstraZeneca group of companies) in the treatment of patients with advanced prostate cancer. Methods: Between February 1996 and October 1997, this open, multicentre study enrolled 120 patients with locally advanced (T3/4) or metastatic (N+ or M1) disease, or an increase in prostate-specific antigen (PSA) level after radical prostatectomy. Patients received goserelin acetate 10.8-mg depot every 12 weeks until clinical progression or interruption for adverse events or other reasons. Results: The mean testosterone concentrations were suppressed to the castration range (≤2 nmol/l) after 4 weeks of treatment and remained suppressed throughout the study. In total, 99/115 (86%) patients had a serum PSA response, and the mean PSA value decreased significantly during treatment (p = 0.006). The mean PSA level at baseline was significantly lower in patients without disease progression compared to those who experienced disease progression (p = 0.0002). Goserelin acetate 10.8-mg depot was well tolerated and there were no injection site reactions. Conclusions: The goserelin acetate 10.8-mg depot is well tolerated with no injection site reactions. It produces PSA responses and provides reliable suppression of serum testosterone.

Transcaval ureter is a rare congenital anomaly characterized by an inferior cava vein duplication producing a vascular ring around the right ureter, usually determining hydroureteronephrosis. The knowledge of this vascular anomaly on imaging examinations permits to avoid erroneous diagnosis of retroperitoneal masses or adenopathy and preoperatively advise the surgeon of potential sources of complications. We describe a case of transcaval ureter studied with multidetector computed tomography. To our knowledge, this is the first case in which computed tomography multiplanar and volume-rendering reconstructions show this rare anomaly.

Background: Stereotactic body radiotherapy (SBRT) can emulate high dose rate brachytherapy (HDR-BRT) dose fractionation. We report our preliminary results using SBRT in monotherapy or pre-external-beam radiotherapy (EBRT) boost in patients with localized prostate cancer (LpC). The primary end point was the evaluation of both acute and late toxicities; secondary end point was the observation of prostate-specific antigen (PSA) nadir. Patients and Methods: Patients with LpC having prostate volume ≤90 cm3 were enrolled in the present study. Patients were treated with SBRT alone or in combined modality (SBRT + EBRT). SBRT was performed using a CyberKnife System (Accuray Incorporated, Sunnyvale, California) and fiducial tracking system. Results: From February 2008 to July 2013, 21 patients for monotherapy (38 Gy/4 fractions) and 5 for combined modality (9.5 Gy/2 fractions plus 46 Gy/23 fractions EBRT) were enrolled. Androgen deprivation therapy (ADT) was administered in 16 of the 26 patients. The median pretreatment PSA was 9.4 (range, 4.5-14.3) ng/mL. All patients completed the planned therapy. Acute Grade 1 toxicity was observed in 18 patients, genitourinary (GU) in 12 / 26 patients, and gastrointestinal (GI) in 6 / 26 patients. Acute Grade 2 GU toxicity was reported in 1 / 26 patients, and Grade 2 GI toxicity was observed in 2 / 26 patients. The median PSA nadir was 0.15 (range, 0.02 = 1.4) ng/mL. Late toxicities were observed in 5 / 26 patients: Grade 1 GU (3 of 26), Grade 2 GU (1 of 26), and Grade 1 GI (1 of 26). Median follow-up was 21.5 (range, 8-65) months. Conclusions: Our preliminary results of SBRT “simulating” HDR for LpC confirm a minimal toxicity and an optimal PSA response. The PSA nadirs appear comparable with HDR-BRT.

Diagnosis of synchronous primary genitourinary tumors are uncommon. Thus far, about 50 cases of synchronous renal tumors have been reported in the literature. We present for the first time a case of a 83-year-old man presenting in the same kidney two separate primary malignancies, a TCC of the renal pelvis and a papillary renal cell carcinoma Type 1. Considered the increased incidence of genitourinary tumors, in presence of a small renal tumor with hematuria, in our opinion, is necessary to pay attention to the diagnostic phase for the chance to highlight an urothelial cancer.

Objective To evaluate quality of life (QoL) and overall survival after radical cystectomy with cutaneous ureterostomies for locally advanced bladder cancer in elderly patients with high surgical risk. Methods Fifty eight patients older than 74 years (mean age 80.6 ± 4.3) with locally advanced bladder cancer (group A), underwent radical cystectomy and ureterocutaneous diversion. Patients completed the EORTC QLQC30 before and six months after surgery to assess functional, clinical, and QoL outcomes. The same evaluation was carried out in a control group (group B) of 29 patients (mean age 82.3 ± 3.8 years), who had refused cystectomy. Questionnaires were also administered to patients of both groups who survived at least 20 months and 5 years. Results All patients presented with an ASA score ≥3. Mean hospital stay was 15.1 days (±4.8) in group A and 23.5 days (±4.1) in group B. No intraoperative complications occurred in group A. Postoperative overall survival evaluated within 6 months in group A was 97% versus 79% in group B ( P Relation between two groups at 6 months for Qol, functional and symptomatic items investigated showed in group A a statistically significant improvement for all parameters ( P Short-term and 20 months overall survival resulted statistically significant in favour of group A ( P Conclusion Radical cystectomy with cutaneous ureterostomy represents a valid alternative in elderly patients with invasive bladder cancer and high operative risk. Comparison between two groups showed a statistically significant difference for almost all the Qol related parameters and for short and medium term overall survival.

Bacillus Calmette-Guerin (BCG) is currently employed in the treatment of superficial bladder cancer but, despite its recognized effectiveness in preventing recurrences and progression, the immune mechanisms behind its antitumor activity remain to be delineated. In this study we provide evidence that a prolonged increase in the plasma levels of IL-2, but not IL-1beta, IL-4, IL-10, IL-2R or TNF-alpha occured in patients affected by bladder cancer following effective BCG treatment. Conversely, a drop in circulating IL-2 was consistently associated with tumor relapse. The level of IL-2 was elevated even further 15 days after the last BCG administration in patients who did not experience tumor recurrence, suggesting a prolonged T cell-mediated response against antigens other than BCG. Our results indicate that a specific type 1 immune response plays a major role in the anti-cancer activity of BCG. In addition, monitoring IL-2 plasma levels may offer a useful tool for predicting tumor recurrences.

Background: Several parameters including inflammatory mediators, hormones, dietary factors, inflammatory genes, and oxidative stress (OS) have been considered to play a role in the development of benign prostatic hyperplasia (BPH). Prostate tissue damage and OS may lead to compensatory cellular proliferation with resulting hyperplastic growth. Methods: We searched MEDLINE for articles in English published up to March 2014 using the key words ‘oxidative stress', ‘antioxidants' and ‘benign prostatic hyperplasia'. Results: Prostatic inflammation can cause the generation of free radicals. The extent of oxidative damage can be exacerbated by a decreased efficiency of antioxidant defense mechanisms. The balance between OS and the antioxidant component also has a role in developing prostate disease. Several works show the role of oxidant products and of depletion of antioxidant substances in BPH patients. It is accepted that free radicals play a role in carcinogenesis and that BPH should be considered a premalignant condition which may evolve into prostate cancer. High OS parameters and low antioxidant activity are more prominent in prostate cancer patients compared with BPH and controls. Conclusions: Further studies are needed to clarify the potential role of antioxidants in BPH also in view of preventing the progression to prostate cancer.

Few studies address alteration of sexual function in women with diabetes and chronic kidney disease (CKD). Quality of life surveys suggest that discussion of sexual function and other reproductive issues are of psychosocial assessment and that education on sexual function in the setting of chronic diseases such as diabetes and CKD is widely needed. Pharmacologic therapy with estrogen/progesterone and androgens along with glycemic control, correction of anemia, ensuring adequate dialysis delivery, and treatment of underlying depression are important. Changes in lifestyle such as smoking cessation, strength training, and aerobic exercises may decrease depression, enhance body image, and have positive impacts on sexuality. Many hormonal abnormalities which occur in women with diabetes and CKD who suffer from chronic anovulation and lack of progesterone secretion may be treated with oral progesterone at the end of each menstrual cycle to restore menstrual cycles. Hypoactive sexual desire disorder (HSDD) is the most common sexual problem reported by women with diabetes and CKD. Sexual function can be assessed in women, using the 9-item Female Sexual Function Index, questionnaire, or 19 items. It is important for nephrologists and physicians to incorporate assessment of sexual function into the routine evaluation protocols.

Objective The present study was a urodynamic evaluation of schizophrenic patients with urinary incontinence occurring during treatment with atypical antipsychotics Methods A total of 12 schizophrenic patients (mean age = 30.7 years, SD = 6.5) presenting urinary incontinence during treatment with atypical antipsychotics at stable doses underwent urodynamic evaluations. Clinical assessment included the administration of Positive and Negative Syndrome Scale (PANSS) Results Four patients out of 12 presented urodynamic patterns consistent with an overactive bladder, while five patients presented reduced bladder compliance; only three patients showed normal urodynamic patterns Conclusion Detrusor overactivity is a condition associated with urinary incontinence in schizophrenic patients treated with atypical antipsychotics. Urodynamic evaluations can improve our knowledge of the mechanisms that subtend atypical antipsychotic-induced incontinence, an invalidating side-effect with strong repercussion on compliance and rehabilitation in schizophrenic patients.

Objective: Androgen-deprivation therapy (ADT) is the usual treatment for locally advanced or metastatic prostate cancer. Osteoporosis is a common complication of ADT. The aim of our study was to evaluate the efficacy of neridronate, a relatively new bisphosphonate to prevent bone loss during androgen ablation. Methods: Sixty patients with prostate cancer and osteoporosis were enrolled and randomly assigned to 2 different treatment regimes: group A (30 patients) treated with maximum androgenic blockage (MAB), and group B (30 patients) treated with bicalutamide 150mg. Each group was divided in 2 subgroups A1–A2 and B1–B2. All patients received calcium and cholecalciferol supplements (500mg of elemental calcium and 400IU cholecalciferol) daily. The A2 and B2 subgroups were also treated with neridronate (25mg intramuscular monthly). Lumbar and femoral bone mineral density (BMD) was evaluated by dualenergy X-ray absorptiometry (DXA), both at baseline and after one year of treatment. Deoxypyridinoline (DPD) and bone-alkaline phosphatase (B-ALP) were determined at the beginning, midstudy and at the end. Results: Patients treated only with calcium and cholecalciferol (A1, B1 subgroups) showed a marked bone loss after 6, and 12 months, with increased levels of DPD and BALP, compared to baseline values. Patients treated with neridronate (A2 et B2 subgroups) showed unchanged levels of these markers. After one year of treatment, lumbar and total hip BMD decreased significantly in patients treated only with calcium and cholecalciferol (A1 subgroup: −4.9% and −1.9% respectively). BMD did not change significantly at any site in patients treated also with neridronate (A2 subgroup: +1% and +0.8% respectively). Lumbar and total hip BMD did not change significantly (−1.5% and −1% respectively) in B1 subgroup. In B2 subgroup an important increase in lumbar spine and the total hip BMD was shown (+2.5% and 1.6% respectively). No relevant side effects were recorded during our study. Conclusion: In conclusion, neridronate is an effective and safe treatment in preventing bone loss in men receiving ADT for prostate cancer.

Introduction: Shortening of telomere is associated with cellular senescence and cancer. This study aims to investigate the relationship between tumor grade and recurrence in relation to telomere length (TL), telomerase activity (TA) and telomere-binding proteins expression (TBPs) in patients with non-muscle invasive bladder cancer (NMIBC). Materials and Methods: Tumor/healthy tissues were collected from 58 patients (35 with and 23 without NMIBC). Cystoscopy was performed at 3, 6 and 12 months to determine recurrence. Tumor grades and recurrence were correlated with TL, TA and TBPs using the Kruskal-Wallis non-parametric test. Results were considered significant at P < 0.05. Results: Histological evaluation indicated 15 patients (42.9%) with high-grade (HG) and 20 patients (57.1%) with low-grade (LG) NMIBC. TL, TA and TBPs were found to be significantly different in tumors as compared with controls. A significant (p < 0.05) difference in the expression of TBPs was observed in the disease-free mucosa of cancer patients as compared with HG and LG tumors. In the follow-up, a total of 11 tumor recurrences were observed; among these eight recurrences were observed in patients with HG tumors and three in patients with LG tumors. TL, Human telomerase reverse transcriptase (hTERT) (that represents TA) and poly (ADP-ribose) polymerase 1 (PARP-1) in tumor samples and telomeric repeat binding factors TRF1, TRF2 and tankyrase (TANK) in normal mucosa obtained from the tumor group were respectively found to exhibit a positive and negative association with the risk of recurrence. Conclusions: Our study demonstrates that TL, TA and TBPs are altered in tumors and non-cancerous mucosa in patients with papillary urothelial NMIBC. Further studies are warranted to identify their suitability as a potential biomarker.

The study assessed the evaluation needs of 81 schools nationwide. A survey questionnaire was constructed and validated by measurement experts. Descriptive statistics were obtained to describe the evaluation activities, practices and areas on evaluation needing technical assistance. Findings show that all schools conduct evaluations mostly on teacher performance (N=29.36%). There was an expressed need for technical assistance practically from planning to utilization of evaluation results, especially in areas of instrumentation and data analysis which were rated highly. The t-test results further indicate no significant difference in the needs between public and private schools. Implications and recommendations related to improve effective training programs that were drawn are discussed in the study.

Endometriosis is a chronic gynaecological disorder characterized by the presence of endometrial tissue outside the uterus. The disease most often affects the ovaries, uterine ligaments, fallopian tubes, and cervical-vaginal region. Urinary tract involvement is rare, accounting for around 1%-2% of all cases, of which 84% are in the bladder. We report a case of isolated lumbar ureteral stenosis due to endometriosis in a 37-year-old patient. The patient came to our observation complaining from lumbar back pain and presented with severe fever. The urological examination found monolateral left positive sign of Giordano. Blood tests evidenced marked lymphocytosis and increased valued of C-reactive protein. Urologic ultrasound showed hydronephrosis of first degree in the left kidney and absence of images related to stones bilaterally. Uro-CT scan evidenced ureteral stenosis at the transition between the iliac and pelvic tracts. We addressed the patient to surgery, and performed laparoscopic excision of the paraureteral bulk, endoscopic mechanical ureteral dilation, and stenting. The histological examination evidenced glandular structures lined by simple epithelium and surrounded by stroma. Immunohistochemical test of the glandular epithelium showed positivity for estrogen and progesterone receptors and moreover stromal cells were positive for CD10. The finding suggested a very rare diagnosis of isolated lumbar ureteral endometriosis.

To evaluate the association between preoperative detrusor underactivity (DU) and symptomatic bladder neck contracture (BNC) in patients undergoing radical retropubic prostatectomy (RRP), in order to identify a possible new risk factor in the etiopathogenic mechanisms of BNC after RRP. A total of 100 prostate cancer patients underwent RRP after preoperative complete urodynamic examination. Detrusor contractility was evaluated by bladder contractility index (BCI), power at maximum flow (WF-Qmax), and maximum velocity of detrusorial contraction (MVDC). Follow-up included uroflowmetry with bladder post-voiding volume evaluation at 3 and 6 months after surgery and repeated urodynamic examination at 12 months. Statistical evaluation was performed using the Student’s t test (P

Objectives: The purpose of this study was to evaluate the role of magnetic resonance (MR) pyelography in patients affected by hydronephrosis due to ureteric stones, in order to identify a pyonephrotic condition. Materials and Methods: In the last 3 years, 315 patients, who had originally been investigated by ultrasonography, were evaluated with MR pyelography in order to define the etiology of obstruction. In 67 patients hydronephrosis was referred as caused by lithiasis. Results: MR pyelography not only confirmed urinary tract dilatation in all patients, but also identified grade and site of obstruction, both in acute dilatation (25 patients) and in chronic obstructions (42 patients). In 7 patients, MR pyelography documented pyonephrosis that was obviously confirmed by nephrostomic drainage. Conclusion: MR pyelography, made with ultrafast breath-hold sequences, has a great value in identifying hydronephrosis in patients with ureteric stones. Furthermore, it provides the chance to identify pyonephrosis requiring an immediate drainage of the kidney before major complications develop.

Objective. Endometriosis is an estrogendependent disease. The incidence of urinary tract endometriosis (UE) increased during the last few years and, nowadays, it ranges from 0.3 to 12% of all women affected by the disease. The ureter is the second most common site affected. The ureteral endometriosis is classified in extrinsic and intrinsic. The aim of this study is to individuate the best treatments for each subset of ureteral endometriosis. Materials and Methods. 32 patients diagnosed with surgically treated UE were retrospectively reviewed. The patients were divided into 3 subsets (intrinsic UE, extrinsic UE with and without obstruction). The patients with intrinsic UE (n = 10) were treated with laser endoureterotomy. The patients with extrinsic UE (n = 22) were divided in two subsets with (n = 16) and without (n = 6) hydronephrosis. All the patients underwent ureteral stenting, and resection and reimplantation was performed in the first group, and when the mass was > 2.5 cm (n = 3) Boari flap was performed. Laparoscopic ureterolysis (shaving) was performed in the second group. Results. In the extrinsic subset of UE, we obtained an high therapeutic success (84%). Conversely, in the intrinsic subset there was a recurrence rate of the disease in 6/10 of the patients (60%). Conclusions. Ureterolysis seems to be a good treatment in extrinsic UE without obstruction. Resection and reimplantation allows excellent results in the extrinsic UE with obstruction. In the intrinsic subset, the endoureterotomy approach is inadequate.

A Phase I study was started to evaluate the locoregional and/or systemic toxic effects of the continuous perfusion of recombinant interleukin-2 (rIL-2) in superficial bladder cancer. Three different dose levels were used: 3 x 10(6) IU/day (3 patients), 9 x 10(6) IU/day (3 patients) and 27 x 10(6) IU/day (3 patients). Two patients (one treated with 3 x 10(6) and another with 27 x 10(6) IU/day of rIL-2) had hematuria after the end of the treatment, one patient had fever (grade I) and 7 of 9 patients experienced hypotension (grade I-II). All effects were not dose related. Routine laboratory tests indicated that no significant variations of biochemical parameters occurred. A phenotypic analysis of white blood cells detectable in the bladder, showed an evident locoregional activation of lymphoid cells. In particular, T lymphocytes expressed activation antigens (such as CD25 and HLA-DR) following treatment with rIL-2. A 6- to 12-month clinical follow-up, showed that all patients but one (which recurred after 5 months) are alive and disease-free. This therefore indicates that the locoregional perfusion of rIL-2 is safe and gives clinical results similar to those obtained using Calmette-Guérin bacillus locoregional instillation, in patients who underwent a transurethral resection of superficial bladder cancer.

Ectopia of the vas deferens (EVD) combined with agenesis of the seminal vesicle, is a rare congenital abnormality. We describe a case of EVD with agenesis of the ipsilateral seminal vesicle, presenting with pneumaturia and frequent urinary tract infection.

INTRODUCTION AND OBJECTIVES: The pathophysiology of vesico-ureteric junction obstruction (VUJO) is still unclear. An abnormal myocyte apoptosis and a significant reduction of neural elements has been described in VUJO. Cholinergic innervations of the upper urinary tract might play a crucial role in the transmission of ureteral peristalsis. Agrins are involved in achetylcholine receptors aggregation during synaptogenesis. Integrins are transmembrane proteins involved in cell differentiation, interaction of the cells with the extracellular matrix, maintenance of tissue integrity and have a main function in embryological development. Aim was to investigate the expression of neural and non-neural agrin and a7-A, a7-B, â1-A and â1-D integrins in obstructed ureteral endings of children affected by VUJO. METHODS: Tissue specimens obtained from ten ureteral reimplants, performed for congenital VUJO, were divided into two parts, distal restricted ureter and dilated ureter above the obstruction. For control group, eight autoptic unaffected distal ureters of matched-aged infants were used. Specimens were exanimated using anti-neural and non-neural agrin, anti-â1-D, -â1-A, -a7-B and -a7-A integrin antibodies. Sections were observed using a confocal laser scanning microscopy. RESULTS: A significant loss of agrins, â1-D and a7-B integrins were detected in restricted ureter coupled to an enhancement of a7-A and â1-A integrins. Differently, a similar expression of agrins, â1-D and a7-B integrins were documented in dilated and control ureters, while a low expression of â1-A and a7-A integrins occurred. CONCLUSIONS: The changes in agrin expression could contribute to altered innervations and function of smooth muscle cells in hypoperistaltic segment in VUJO. Moreover, we observed an alternatively spliced isoform of both a and â integrin subunits. It has been shown that cell matrix adhesion via integrins protects from apoptosis, allowing cell survival. Expression of â1-A and a7-A integrins is developmentally regulated during embryogenesis and a delayed rearrangement of cytoskeleton of SMC in VUJO might be linked to a post-natal splicing from a7A and â1A to, respectively, a7B and â1D integrins. These data perfectly are in accordance with the clinical evidence of a possible post-natal healing of congenital VUJO. Our data suggest that a main anomaly in VUJO might be attributed to an abnormal expression of agrins and to an alteration of smooth muscle cell cytoskeleton, promoting an impairment of contractile function.
