Priapism is defined as an erection lasting for more than 4 hours without sexual stimulation. It is grouped into 3 subtypes: ischemic (low-flow), nonischemic (high-flow), and stuttering priapism. Herein we describe a rare event of high-flow state as a result of conversion from a delayed ischemic priapism after a T-shunt with tunneling. To our knowledge, there is a paucity of reported cases, and the pathophysiology is still unclear. Clinicians should be aware of this uncommon but known scenario in case of penile tumescence after shunting procedure for ischemic priapism; penile Doppler ultrasound and selective pudendal angiography represent essential tools for diagnosis and treatment of this rare condition. In delayed ischemic priapism persisting for >36 hours, patients should be counseled about the irreversible damages of the cavernosal muscle and erectile dysfunction to consider an early penile prosthesis implantation with a satisfactory long-term functional outcome, decreasing the risks related to a distal shunt procedure.

Background Plaque incision and grafting (PEG) is one of the mainstays in surgical therapy for severe penile curvature in Peyronie's disease (PD). Different kinds of grafts are available for covering albugineal defects during PEG, both allografts and xenografts. However, to date, none of these proved superior to others. Objectives To compare two different types of xenograft, porcine dermal matrix and bovine pericardium matrix in PEG for PD. Materials and methods From 2010 to 2019, 63 patients with PD underwent PEG, using porcine dermal (n = 25; Group 1) and bovine pericardium (n = 38; Group 2) grafts. Long-term outcomes were evaluated through multi-disciplinary questionnaires administration by phone interview. The following items were considered: correction of penile bending, quality of erection, intercourse ability, penile shortening, and sensitiveness. Overall satisfaction and impact of surgery on sexual activity and quality of life were also investigated. Results Plaque median (IQR) size was 29 (22-33) mm and was smaller in Group 1 (27.5 vs. 31 mm; P = .03). Complete follow-up data were available for 53 patients (84%). Considering post-operative outcomes, no differences were found when considering ED rates, penile shortening, sensitiveness, complications, and penile straightening (all P > .1). Patients in Group 2 were more likely to have palpable penile nodules at follow-up (20.6 vs. 0%; P = .03). However, patient's post-operative sexual life satisfaction was consistent between the two groups, with just 1 (5.3) and 8 (23.5) patients in Group 1 and 2 respectively referring a worsening in sexual life satisfaction (P = 0.2). At follow-up, 84.9% of patients that would still undergo surgery for PD, with no statistical difference between the two groups (P = .4). Conclusions Corporoplasty with PEG is an effective treatment for men with PD. Porcine dermal and bovine pericardium xenografts seem to have similar long-term outcomes.

Object To evaluate surgical outcomes after implantation of the Zephyr ZSI 475 inflatable penile prosthesis (IPP) and patients’ quality of life. Patients and methods From December 2014 to September 2018, 15 patients underwent prosthesis implantation with ZSI 475. A retrospective review of clinical data was performed. Patients’ quality of life after implantation was investigated with Quality-of-Life-and-Sexuality-with-Penile-Prosthesis (QoLSPP) questionnaire. Results The median age of patients was 57 years and the average follow-up was 22 months. Twelve patients received a standard implantation due to severe erectile dysfunction (ED); three patients also presented penile curvature and additional corporoplasty with grafting was necessary. Three procedures had to be interrupted due to defects of the insertion tools. In one case a manufacturing defect resulted in a pump leak. In one case a severe postoperative complication occurred, which requested explantation of the device. During the follow-up, four patients experienced mechanical failure of the prosthesis. Results of QoLSPP questionnaire at 12 months were skewed toward the positive end of the scale in all domains. Conclusion In our initial experience, ZSI 475 suffered a high rate of mechanical failures; on the other hand, the company showed great commitment in order to improve the quality and reliability of the device. The lower cost of t ZSI 475 may add to the chances of the product to become a cost-effective alternative to treat those patient who need a IPP.

Objective: The aim of this study is to assess the management of refractory ischemic priapism (IP) by the immediate insertion of a soft penile prosthesis (sPP). Patients and methods: We identified men affected by IP who underwent early sPP placement from May 2017 to October 2019. All patients underwent a detailed medical history review; intraoperative, postoperative features and adverse events were recorded. We evaluated the penile lengthening and bending, presence of complementary erection, ability to have sexual intercourse, postoperative sexual life satisfaction (International Index of Erectile Function [IIEF] questionnaire - question number 5). A cost-analysis was included. Results: A total of six patients were identified. Median time (range) since onset was 78 (48-108) hours with a mean age (SD) of 33 (6.9) years. Median operative time (range) was 82 minutes (62-180). No complications were recorded. Median follow- up was 9 months (range 3-17). No significant loss of penile length, neither penile angulation was recorded. Despite a transient reduction of penile sensitivity, all patients reported satisfactory sexual intercourse (mean score question number 5 from IIEF-5 of 4). The cost of sPP was € 1769,00 with a surgeryrelated reimbursement fee from the National Health System of € 3856,75. Conclusions: The insertion of a sPP for patients with refractory IP results in immediate pain relief, preservation of sexual function and penile size, with a higher surgery reproducibility in an emergency. In addition to this, financial and resource burdens of IP on the health-care system can be potentially reduced.

The SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2) was first reported in December 2019, then its rapid spread around the world caused a global pandemic in March 2020 recording a high death rate. The epicenter of the victims moved from Asia to Europe and then to the United States. In this Pandemic, the different governance mechanisms adopted by local health regional authorities made the difference in terms of contagiousness and mortality together with a community strong solidarity. This document analyzes the andrological urgencies management in public hospitals and in private practice observed in Italy and in particular in the most affected Italian Regions: Emilia-Romagna and Marche.

BACKGROUND: We aimed to assess the detection rate of overall PCa and csPCa, and the clinical impact of MRI/TRUS fusion targeted biopsy (FUSION-TB) compared to TRUS guided systematic biopsy (SB) in patients with different biopsy settings. METHODS: Three hundred and five patients were submitted to FUSION-TB, divided into three groups: biopsy naïve patients, previous negative biopsies and patients under active surveillance (AS). All patients had a single suspicious index lesion at mpMRI. Within these groups, we enrolled men underwent both to FUSION-TB and SB in the same session. Overall detection rate of PCa and csPCa for the two biopsy methods were compared separately between the three groups of patients. RESULTS: No differences were observed between the three groups concerning clinical and radiological characteristics. We found no differences in terms of overall PCa detection (66% vs. 63.8%, P=0.617) and csPCa detection (56.4% vs. 51.1%; P=0.225) concerning biopsy naïve patients. In patients previously submitted to a negative biopsy, FUSION-TB showed higher detection rate of csPCa compared to SB alone (41,3% vs. 27% respectively, P=0.038). In patients under AS, no differences were observed between FUSION-TB and SB in terms of overall PCa (50% vs. 73.1%) and csPCa (30.8% vs. 26.9%, respectively; P=0.705) detection. CONCLUSIONS: Our results suggest that in men with previously negative biopsy, FUSION-TB showed significantly higher diagnostic performance for clinically significant PCa as compared to SB. Combination of FUSION-TB and SB should be recommended in AS population to offer higher chance of csPCa diagnosis.

We agree that the ideal strategy in patients withan SMT would be to follow them with periodic USand perform surgery only in those who show sig-nificant growth during followup. This is our actualpolicy in masses less than 5 mm in diameter. Inthis group few patients required surgical explora-tion during followup. It is likely that in cases ofsuch small lesions strict surveillance may notchange the progression of germinal tumors, as re-ported by Bieniek et al, who noted a mean lesiondiameter of 4.142.0 mm (reference 1 in EditorialComment).However, sparse data are available in the litera-ture on the natural history of larger masses whenleft untreated. Our study shows that even largerlesions up to 20 mm in diameter may be benign, indicating that strict surveillance might be justifiedeven for masses larger than 5 mm. Our experiencealso demonstrates that with increasing lesion sizethe risk of cancer significantly increases 7 times permm. This information could be used to bettercounsel patients about the risk of harboring TC andeventually better support a followup strategy inpatients with an STM.We believe that 2 research lines which might helpus in the near future are 1) study of the individuallesion growth rate, which could differentiate benignfrom malignant lesions, and 2) new imaging diag-nostic tests such as contrast enhanced US1ortesticular magnetic resonance imaging, whichmight improve the diagnostic performance of scrotalUS.

BACKGROUND: We report long-term oncologic outcomes in patients with positive surgical margins (PSMs) at radical prostatectomy (RP) and the oncologic impact of different scenarios of PSMs presentation. METHODS: We selected 494 men with at least 3 years follow-up after surgery. PSMs patterns were recorded as: burden (focal vs multifocal), site (apical-anterior vs posterolateral vs base-bladder neck vs multiple) and side (unilateral vs bilateral). Kaplan-Meier curves depicted the clinical recurrence-free survival (CR-FS) rates at 10-year in the overall population, after biochemical recurrence and according to different PSMs patterns. Multivariate Cox-regression analysis was performed to predict CR. RESULTS: Overall, PSMs sites were apical-anterior, postero-lateral, base-bladder neck and multiple in 19.8%, 23.7%, 3.4% and 43.8%, respectively. Out of 494 patients, 278 (56.3%) had a focal margin, while 216 (43.7%) had a multifocal margin. In 268 (54.3%) and 87 (17.6%) men, PSMs were unilateral and bilateral, respectively. Median follow-up was 93 months. No significant differences were found in CR-FS rates after stratifying according to burden and site of PSMs. Men with unilateral PSMs experienced significant higher CR-FS rates compared to those with bilateral PSMs (87.1% vs. 71,3% at 10 years, p

Objective:To evaluate the features and prognosis of melanoma of glans penis and urethra, with the presentation of a significant case report.Materials and methods:A systematic literature review was performed using the MEDLINE (PubMed) and Cochrane Libraries databases to identify all cases of male mucosal melanoma reported.Results:Two hundred fifty-two patients with male mucosal primary melanoma were found. Glans penis and fossa navicularis as primary site includes the 81.6% of all lesions considered. Median Breslow’s depth is 2.1 mm, whereas nine in situ melanomas have been reported. At the diagnosis, the disease was at a non-localized stage in 21.4% for glans penis melanomas and 11.7% urethral lesions, respectively. The 2 and 5-year survival for glans melanoma is 62.5% and 38.4%; higher rates were observed in the 2012–2020 period (76% and 58.8%, respectively). Two-year survival for urethral melanomas is 66.7%, while 5-year survival is 12.5%. 22 patients survived over 5 years with a Breslow’s depth reported always Conclusion:Melanoma of the glans penis and urethra is a rare neoplasm associated with a poor prognosis, however recent reports show higher survival rates. Surgery remains the mainstay for a localized disease. Taking into account the small number of cases reported, topical imiquimod seems to be a valid non-surgical alterative for melanoma in situ. The use of immunotherapy and targeted therapy should be considered only in an adjuvant setting according to the recommendations of cutaneous melanoma; however, additional clinical data on male mucosal melanoma are needed to draw definitive conclusions.

PURPOSE: To assess survival and competing causes of mortality in prostate cancer (PCa) patients referred to radical prostatectomy through a combination of unfavorable characteristics. PATIENTS AND METHODS: We evaluated 615 PCa patients referred to radical prostatectomy and pelvic lymph node dissection at single tertiary-care center with at least one adverse feature (AF): preoperative prostate-specific antigen ≥ 20 ng/mL, pathologic Gleason score 8 to 10, and no organ-confined disease at final pathology (seminal vesicle involvement, positive surgical margins, and/or lymph node invasion). Kaplan-Meier analyses were used to assess cancer-specific mortality (CSM)-free survival rates by stratifying patients into 3 risk categories according to the number of AFs (namely, 1, 2, and 3 AFs). Multivariable competing risk Cox regression analyses were used to assess CSM and other cause of mortality. RESULTS: Significant differences were found in terms of preoperative and pathologic tumor characteristics, adjuvant therapies, and biochemical recurrence (BCR). Men with 1 AF had higher CSM-free survival estimates compared to those with 2 and 3 AFs (92.8% vs. 84.2% vs. 27.7% at 10 years' follow-up, P < .001). Moreover, the presence of 3 AFs (hazard ratio [HR], 2.96), postoperative adjuvant treatment status (HR, 2.44), and time to BCR (HR, 0.96) were all independent predictors of CSM (P ≤ .04). Age at surgery and time to BCR were the only independent predictors of other causes of mortality (P ≤ .0009). CONCLUSION: The risk group stratification according to the number of AFs could help physicians to accurately predict oncologic outcomes and to select PCa patients for the most appropriate postoperative strategies.

Renal oncocytosis is a rare pathological condition characterised by the presence of multiple oncocytic tumours with a spectrum of histological features ranging from renal oncocytoma, hybrid oncocytic tumour and rarely chromophobe renal cell carcinoma, sometimes overlapping. Here we retrospectively analysed histological, immunohistochemical (IHC), and cytogenetic features of 42 lesions in 11 patients with renal oncocytosis, not associated with Birt-Hogg-Dubé syndrome. The histology of all the lesions was blindly reviewed by three dedicated genitourinary pathologists. IHC for cytokeratin 7 (CK7) and fluorescence in situ hybridisation (FISH) for copy number variation of chromosomes 1, 6, 7 and 17 were performed in all 42 nodules. Among the 42 lesions 36 (85.7%) were histologically renal oncocytomas, two (4.76%) 'hybrid oncocytic tumours' (HOT), one (2.4%) clear cell renal cell carcinoma (ccRCC), one (2.4%) papillary renal cell carcinoma (pRCC), one typical angiomyolipoma (2.4%), and one mixed epithelial/stromal tumour of the kidney (2.4%). FISH analysis confirmed the histological diagnosis of all the lesions. We show that most patients with renal oncocytosis harbour benign or low malignant potential tumours that can be treated conservatively.

Aim of the Study: Radical Orchiectomy (RO) represents the standard treatment for patients (pts) with suspicious testicular masses and normal contralateral testis. Because a considerable amount of small testicular masses (STM) are benign lesions, this practice exposes to a substantial risk of overtreatment with possible medical-legal consequences. The aim of this study is to report results of testis sparing surgery (TSS) in the treatment of STM (

Aim: The success of Robot Assisted Laparoscopic Prostatectomy (RALP) is mainly due to his relatively short learning curve. Twenty cases are needed to reach a “4 hours-proficiency”. However, to achieve optimal functional outcomes such as urinary continence and potency recovery may require more experience. We aim to report the perioperative and early functional outcomes of patients undergoing RALP, after a structured modular training program. Methods: A surgeon with no previous laparoscopic or robotic experience attained a 3 month modular training including: a) e-learning; b) assistance and training to the operating table; c) dry console training; d) step by step in vivo modular training performing 40 surgical steps in increasing difficulty, under the supervision of an experienced mentor. Demographics, intraoperative and postoperative functional outcomes were recorded after his first 120 procedures, considering four groups of 30 cases. Results: All procedures were completed successfully without conversion to open approach. Overall 19 (15%) post operative complications were observed and 84% were graded as minor (Clavien I-II). Overall operative time and console time gradually decreased during the learning curve, with statistical significance in favour of Group 4. The overall continence rate at 1 and 3 months was 74% and 87% respectively with a significant improvement in continence rate throughout the four groups (p = 0.04). Considering those patients submitted to nerve-sparing procedure we found a significant increase in potency recovery over the four groups (p = 0.04) with the higher potency recovery rate up to 80% in the last 30 cases. Conclusions: Optimal perioperative and functional outcomes have been attained since early phase of the learning curve after an intensive structured modular training and less than 100 consecutive procedures seem needed in order to achieve optimal urinary continence and erectile function recovery.

ntroduction & Objectives: Radical Orchiectomy (RO) represents the standard treatment for patients (pts) with suspicious testicular masses and normal contralateral testis. Because a considerable amount of small testicular masses (STM) are benign lesions, this practice expose to a high risk of overtreatment. The aim of this study is to report results of testis sparing surgery (TSS) in the treatment of STM(< 2cm) and to identify an updated treatment strategy. Materials & Methods: We retrospectively reviewed clinical history of pts treated with TSS for STM

Nutcracker syndrome (NCS) refers to the compression of the left renal vein (LRV) between the aorta and the superior mesenteric artery. It can cause both microscopic and gross haematuria, with or without flank pain. The diagnosis is often delayed in a majority of symptomatic patients. On the other hand, the use of CT in routine abdominal explorations has increased the detection of the compression of the LRV in healthy and asymptomatic patients, but its diagnostic value remains uncertain. In this paper, we report 3 cases of the NCS associated with an increased blood flow in the LRV, due to different conditions, which we believe could produce the appearance of clinical symptoms.

The widespread use of abdominal imaging has led to an increasing detection of small renal masses, and approximately 20–30% of those tumors will prove to be benign, with low metastatic potential if not immediately treated. In elderly or comorbid patients diagnosed with small renal masses, competing cause mortality seems to exceed cancer-specific mortality at short- and intermediate-term follow up. In these cases, surgery might represent an overtreatment, and an expectant management, such as active surveillance, might be proposed. According to the current available evidence, active surveillance is a safe and reasonable option for patients with renal tumors ≤4 cm (cT1a) and short life expectancy. A few studies with short-term follow up reported the preliminary results of active surveillance even in cT1b–cT2 tumors, with acceptable risk of disease progression and mortality, even if this approach should be considered in this setting only for highly-selected and well-informed patients. Furthermore, surveillance protocols can be proposed in selected patients with uncomplicated benign tumors, such as angiomyolipomas, in which active surveillance should be considered the initial standard management. At present, reliable clinical predictors of a tumor's growth rate and aggressiveness are not available. Renal tumor biopsy is useful in the clinical work-up of patients who are candidates for active surveillance, in order to improve patient selection based on tumor histological characterization. Despite the proof of safety offered by expectant management for small renal masses in selected patients, further prospective studies with longer follow up are required in order to confirm the indications and long-term oncological outcomes of active surveillance protocols for renal tumors.

Objective: To offer a comprehensive account of surgical outcomes on a defined series of patients treated with radical retropubic prostatectomy (RRP) for prostate cancer in a single European Center after 5-year minimum follow-up according to the Survival, Continence and Potency (SCP) system. Material and methods: We evaluated our Institutional database of patients who underwent RRP from November 1995 to September 2008. Oncological and functional outcomes were reported according to the recently proposed SCP system. Results: The 5- and 10-year biochemical recurrence-free survival rates were 80.1% and 55.8%, respectively. At the end of follow-up, 611 (78.5%) patients were fully continent (C0), 107 (13.8%) used 1 pad for security (C1) and 60 (7.7%) patients were incontinent (C2). Of the 112 patients who underwent nerve-sparing RRP, 22 (19.6%) were fully potent without aids (P0), 13 (11.6%) were potent with assumption of PDE-5 inhibitors (P1) and 77 (68.8%) experienced erectile dysfunction (P2). The combined SCP outcomes were reported together only in 95 (12.2%) evaluable patients. In patients preoperatively continent and potent, who received a nerve-sparing and did not require adjuvant therapy, oncological and functional success was attained by 29 (30.5%) patients. In the subgroup of 508 patients not evaluable for potency recovery, oncological and continence outcomes were obtained in 357 patients (70.3%). Conclusion: Survival, Continence and Potency (SCP) classification offer a comprehensive report of surgical results, even in those patients who do not represent the best category, thus allowing to provide a much more accurate evaluation of outcomes after RP. 2014 Elsevier Ltd.

Introduction We investigated the diagnostic performance of in-bore endorectal magnetic resonance imaging-guided biopsy (MRI-GB) with a 1.5-T MRI scanner using a 32-channel coil in patients with suspected prostate cancer (PCa). Patients and Methods Seventy patients with ≥ 1 suspicious area found on the preliminary multiparametric MRI scan were enrolled. The index lesion was defined as the lesion with the greatest Prostate Imaging Reporting and Data System, version 2 (PIRADS-v2), score. MRI-GBs were performed with a nonmagnetic biopsy device, needle guide, and titanium double-shoot biopsy gun with dedicated software for needle tracking. Clinically significant PCa was defined as the presence of Gleason score ≥ 7 in the biopsy specimen. Results Seventy index lesions were scheduled for MRI-GB. The median PIRADS-v2 score and the median number of cores per patient was 4 of 5 (interquartile range, 3-5) and 2 (interquartile range, 1-3), respectively. The PCa detection rate was 45.7%. Of the 70 patients, 24 (75%) had clinically significant PCa, with a significant correlation between the PIRADS-v2 score and the Gleason score in the MRI-GB cores ( r = 0.839; 95% confidence interval, 0.535-0.951; P = .003). According to the PIRADs-v2 scheme, the proportion of PCa in the central and anterior regions of the gland was greater in the entire population and in the subgroup of patients with a history of negative transrectal ultrasound-guided biopsy findings ( P ≤ .01 for all). On multivariate analysis, a PIRADS-v2 score of 5 of 5 correlated significantly with the likelihood of PCa at biopsy (hazard ratio, 4.69; 95% confidence interval, 0.92-23.74; P = .04). No major complications were recorded. Conclusion MRI-GB has a high detection rate for PCa, especially for lesions located in the central and anterior regions of the prostate.

Background Small renal masses (SRMs; ≤4 cm) represent a challenging issue. Computed tomography (CT) is widely used for investigating renal tumors even if its ability to differentiate among the different subtypes has not yet been definitively established. Purpose To assess the potential role of the morphological features and angiodynamic behavior on multiphasic CT in the preoperative evaluation of SRMs. Material and Methods The CT images of 80 patients with SRMs who underwent surgical resection at our institution were retrospectively reviewed. The morphological features, the pattern, and the quantitative analysis of enhancement were assessed for each lesion and were correlated with the histological subtypes. Results Overall, 81 SRMs were evaluated. Final pathological examination showed 30 (37%) oncocytomas, 22 (27.2%) clear cell renal cell carcinomas (ccRCCs), 16 (19.8%) papillary RCCs (pRCCs), and 13 (16%) chromophobe RCCs (chRCCs). Of the morphological features, only necrosis was significantly associated with ccRCC ( P = 0.047). The analysis of enhancement allowed the identification of two groups of lesions, based on arterial behavior: hypervascular (oncocytomas/ccRCC) and hypovascular (chRCC/pRCC) lesions. A significant difference between the two groups in terms of degree of enhancement on CT phases was found ( P Conclusion Except for necrosis, the morphological features are not useful in making a correct diagnosis in the case of SRMs. The angiodynamic behavior on multiphasic CT showed high accuracy in differentiating between hypovascular and hypervascular tumors; this differentiation could be useful for deciding on the most appropriate clinical management of SRMs.

Resumen Objetivos Evaluar la influencia de la preservacion del esfinter interno muscular y la uretra proximal en la recuperacion de la continencia despues de la prostatectomia radical (PR). Material y metodos Cincuenta y cinco pacientes consecutivos con cancer de prostata confinado al organo se sometieron a PR con preservacion del esfinter interno muscular y la uretra proximal (grupo 1), y se compararon con 55 pacientes sometidos a un procedimiento estandar (grupo 2). Las tasas de continencia se evaluaron mediante un cuestionario autoadministrado a los 3, 7 y 30 dias y 3 y 12 meses despues de la retirada del cateter. Resultados El grupo 1 tuvo una recuperacion mas rapida de la continencia que el grupo 2 a los 3 dias (50,9 vs. 25,5%; p = 0,005), a los 7 dias (78,2 vs. 58,2%; p = 0,020), a los 30 dias (80,0 vs. 61,8%; p = 0,029) y a los 3 meses (81,8 vs. 61,8%; p = 0,017); no hubo diferencia estadisticamente en terminos de continencia a los 12 meses entre los 2 grupos. El analisis de regresion logistica multivariante de la continencia mostro que la tecnica quirurgica se asocio significativamente con un tiempo temprano hasta la continencia a los 3 y 7 dias. Ninguno de los 2 grupos presento diferencias significativas en cuanto a margenes quirurgicos. Conclusiones Nuestra tecnica modificada de PR con preservacion del esfinter interno muscular liso, asi como de la uretra proximal durante la diseccion del cuello de la vejiga, dio como resultado un aumento de la continencia urinaria temprana a los 3, 7 y 30 dias y 3 meses despues de la retirada del cateter. La tecnica no aumenta la tasa de margenes positivos ni la duracion del procedimiento.

The anterior nutcracker syndrome is defined by the compression of the left renal vein between the aorta and superior mesenteric artery, usually related to the occurrence of hematuria. We report the case of an uncommon complication of the nutcracker syndrome. A 75-year-old woman was referred to our institution for left flank pain without hematuria. Multiphasic computer tomography urography showed a condition of left renal vein entrapment between the aorta and superior mesenteric artery with the development of left gonadal vein varicosities at the level of the renal hilum; a pyeloureteral junction compression with dilation of the pyelocalyceal system coexisted. To our knowledge, this is the first report of the association between nutcracker syndrome and pyeloureteral junction obstruction.

About 40% of all patients undergoing radical treatment for localized prostate cancer (PCa) develop biochemical relapse (BCR) during lifetime but only 10-20% of them will show clinically detectable recurrences. Prostatic bed, pelvic or retroperitoneal lymph nodes (LN) and bones (especially the spine) are the sites where we must focus our attention in the early phase of PSA relapse. Time to PSA relapse, PSA kinetics, pathological Gleason score and pathological stage are the main factors related to the likelihood of local vs. distant relapse. Before an extensive diagnostic work-up in patients with BCR, is mandatory to understand if there is a therapeutic consequence or not for the patient. Current imaging techniques have some potential but many limits are yet encountered in the diagnosis of disease relapse. Transrectal ultrasound (TRUS) and Multiparametric Magnetic Resonance Imaging (MRI) have low accuracy in the detection of the recurrence. Today, Choline PET/CT may visualize the site of recurrence earlier, with better accuracy than conventional imaging, in a single step and even in the presence of low PSA level. In recent years, the new radiotracer (18)F-FACBC has been proposed as a possible alternative radiopharmaceutical to detect PCa relapse. From a clinical point of view, first clinical studies showed very promising and reproducible results with an improvement in sensitivity is about 20-25% with respect to Choline PET/CT, rendering the FACBC the possible radiotracer of the future for PCa. In conclusion, many improvements have been recently achieved in imaging techniques for PCa restaging, essentially in Nuclear Medicine and MRI, but negative results remain in many cases. Low sensitivity, costs, availability of technologies and confirmation of the results remain the major limitations in most cases.

PURPOSE: To evaluate, by using a standardized reporting methodology, the perioperative complications and mortality in patients who underwent radical cystectomy. MATERIALS AND METHODS: We retrospectively reviewed all data of 404 consecutive patients who underwent radical cystectomy from 1995 to 2009 for nonmetastatic bladder cancer at the same academic center. Perioperative complications and perioperative mortality were defined as any adverse event or death from any cause within 90 days of surgery. All perioperative complications were reported according to the Martin criteria and were graded according to the Clavien system (grade 1-5). Univariate and multivariate analyses for the clinical and pathologic characteristics were used to evaluate predictors of complications. RESULTS: A total of 296 complications occurred in 209 (51.7%) patients. Among them, 139 (34.4% of the entire population) had only a '"minor"' (grade 1-2) complication, whereas 70 (17.3%) had a "major" (grade 3-5) complication. Eighteen (4.5%) patients died within 90 days after surgery. At univariate analysis, age ≥75 years (2P = .018), serum creatinine level ≥1.4 mg/dL (2P = .025), American Society of Anesthesiologists (ASA) score of 3 to 4 (2P < .001) were significant predictors of complications after 30 days from surgery; conversely, the ASA score was the only significant predictor of complications after 90 days. At multivariate analysis, only the ASA score was independently correlated with the development of complications at 30 and 90 days of follow-up (2P < .001). CONCLUSIONS: Radical cystectomy is one of the most complex procedures in urology, with a high rate of complications and mortality. The use of a standardized methodology is the only way to estimate the actual rate and the severity of complications.

What's known on the subject? and What does the study add? Lymph node (LN) status is one of the most important prognostic variables in patients undergoing radical prostatectomy, but not all patients with node-positive PCa are at the same risk of recurrence and cancer-specific death. In this study we evaluated the role of pathological variables in stratifying the risk of cancer death in patients with prostate cancer. Patients with 1–3 positive LNs and Gleason score (GS) ≤7 experienced better CSS and OS than those with >3 metastatic LNs and/or GS >7. This evidence could allow urologists to better predict oncological outcomes of patients and select more appropriate therapeutic management. Objectives To evaluate the outcomes in patients with node-positive prostate cancer (PCa) after radical prostatectomy (RP) and pelvic lymph node dissection (PLND) according to the number of positive lymph nodes (LNs). To identify different risk groups among patients with node-positive PCa. Patients and Methods We evaluated 98 consecutive patients with pN1M0 PCa who underwent RP between November 1995 and May 2011. Kaplan–Meier and Cox proportional univariable and multivariable regression models were used to analyse the survival rates. Patients were divided into two groups according to number of positive LNs using the most informative positive LN theshold for predicting survival, then into three different risk groups according to number of positive LNs and pathological Gleason score (GS). Results Mean (range) follow-up was 68.4 (10–192) months. Patients with 1–3 positive LNs (n = 75; 76.5%) had significantly better cancer-specific survival (CSS) and overall survival (OS) compared with those with >3 positive nodes (n = 23; 23.4%; P < 0.01). Patients with 1–3 positive LNs and pathological GS ≤7 (Group 1) had significantly better CSS than those with >3 positive LNs or GS 8–10 (Group 2 [P = 0.015]). Group 2 patients, moreover, had significantly better CSS (P = 0.019) and OS (P = 0.021) than those with >3 positive LNs and GS 8–10 (Group 3). Conclusions Patients with 1–3 positive LNs have higher CSS and OS rates than those with >3 metastatic LNs. Taking into account the pathological GS, as well as the number of positive nodes, three risk group categories with considerable differences in terms of survival can be found. Patients with LN-positive PCa should be stratified into different groups according to these two measures, to obtain a better prediction of oncological outcomes.

BACKGROUND: Routine pathological examination can miss micro-metastatic tumor foci in the lymph nodes (LN) of patients with prostate cancer (PCa) that undergo radical prostatectomy and pelvic lymph node dissection (PLND). The aim of the present prospective study was to evaluate the impact of micrometastases assessed by serial section (SS), immunohistochemistry (IHC), and Real-time Polymerase Chain Reaction (RT-PCR) in patients undergoing radical prostatectomy with extended PLND. MATERIALS AND METHODS: 32 consecutive patients who underwent radical prostatectomy with extended PLND (obturator, internal/external and distal 2 cm common iliac lymph-nodes (LN)) for intermediate (clinical T1c-T2 and PSA:10-20 ng/mL and clinical Gleason Score = 7) or high (clinical stage T3 or PSA>20 or clinical Gleason Score = 8-10) PCa were enrolled. The nodes were processed by the one uropathologist, both according to the routine pathological examination (analysis of the central section for 4 mm nodes or every 2 mm for LN>4 mm), which served as comparative method, both according to SS, IHC with antibodies against PSA and broad-spectrum Cytokeratins (BSCK), and quantitative RT-PCR targeting PSA, PSMA (PS Membrane Antigen), and Glucuronidase-S-Beta (GUSB) mRNA, that are over-expressed in prostatic cancer cells. RESULTS: A total of 628 LN were analyzed, with a mean number of LN removed of 19.6 (SD = 7.2). Applying the routine pathological examination, 10 (31.2%) patients and 23 (3.9%) LN resulted positive for nodal involvement, with mean positive LN of 2.2 (SD = 1.4). After applying the SS and the molecular method of analysis (IHC and RT-PCR), micrometastases were found in 7 LN (SS showed micrometastases in 3 of them, IHC in 6 of them and RT-PCR in 7 of them); a total of 3 (9.3%) node-negative patients showed micrometastases at routine pathological examination (in 2 patients with RT-PCR and in 1 with IHC). CONCLUSIONS: The significance of micrometastases in PCa and the potential therapeutic role of PLND is not yet clarified, but the molecular analysis of the LN can detect a significant percentage of patients who harbor micro-metastatic PCa missed at routine pathological examination, and can enhance the accuracy of lymphadenectomy as a staging method.

Renal leiomyomas are rare benign tumours of the kidney originating from muscle cells. They are usually found by an autopsy,whether the patient is asymptomatic or has symptoms (i.e., abdominal/flank pain, hematuria, palpable mass). Today the widespread use of ultrasonography and computed tomography has increased the detection of clinically asymptomatic renal leiomyomas. The differential diagnosis between leiomyomas and other malignant lesions (above all renal cell carcinoma or leiomyosarcoma) is still possible by histological examination. Radiological examinations are not sufficient for the differential diagnosis. Renal leiomyomas have no aggressive behaviour and they usually do not metastasize. The prognosis, after surgery, is excellent without recurrence. We report a case of leiomyoma in a 31-year-old man who presented hematuria and flank pain. We also review the literature and provide a summary of clinical, radiological and histological features of renal leiomyomas.

OBJECTIVE: • To assess the impact of pelvic lymph node dissection (PLND) and of the number of lymph nodes (LNs) retrieved during radical prostatectomy (RP) on biochemical relapse (BCR) in pNX/0/1 patients with prostate cancer according to the clinical risk of lymph node invasion (LNI). PATIENTS AND METHODS: • We evaluated 872 pT2-4 NX/0/1 consecutive patients submitted to RP between October 1995 and June 2009, with the following inclusion criteria: (i) a follow-up period ≥12 months; (ii) the avoidance of neoadjuvant hormonal therapy or adjuvant hormonal and/or adjuvant radiotherapy; (iii) the availability of complete follow-up data; (iv) no pathological T0 disease; (v) complete data regarding the clinical stage and Gleason score (Gs), the preoperative prostate-specific antigen (PSA) level and the pathological stage. • The patients were stratified as having low risk (cT1a-T2a and cGs ≤6 and PSA level < 10 ng/mL), intermediate risk (cT2b-T2c or cGs = 7 or PSA level = 10-19.9) or high risk of LNI (cT3 or cGs = 8-10 or PSA level ≥ 20). • The 872 patients were divided into two LN groups according to the number of LNs retrieved: group 1 had no LN or one to nine LNs removed; group 2 had 10 or more LNs. • The variables analysed were LN group, age, PSA level, clinical and pathological stage and Gs, surgical margin status, LN status and number of LN metastases; the primary endpoint was the BCR-free survival. RESULTS: • The mean follow-up was 55.8 months. • Of all the patients, 305 (35%) were pNx and 567 (65.0%) were pN0/1. • Of the 567 patients submitted to PLND, the mean number of LNs obtained was 10.9, and 49 (8.6%) were pN1. • In the 402 patients at low risk of LNI, LN group was not a significant predictor of BCR at univariate analysis, while in the 470 patients at intermediate and high risk of LNI, patients with ≥ 10 LNs removed had a significantly lower BCR-free survival at univariate and multivariate analysis. CONCLUSION: • In our study population, a more extensive PLND positively affects the BCR-free survival regardless of the nodal status in intermediate- and high-risk prostate cancer.
