Early Inflatable penile prosthesis implantation offers superior outcomes compared to delayed insertion following ischemic priapism: a narrative review.

Ischemic priapism is a urological emergency which may lead to irreversible erectile dysfunction. One of the accepted treatments is penile prosthesis implantation. Given the scarcity of studies directly comparing timing of penile prosthesis insertion after ischemic priapism, consensus remains elusive. We aim to compare different studies in the literature concerning advantages and disadvantages of early versus delayed inflatable penile prosthesis following ischemic priapism. We analyzed 8 articles that investigated immediate and delayed inflatable penile prosthesis placement after ischemic priapism. Early inflatable penile prosthesis placement is associated with better outcomes, including pain relief, priapism resolution, penile shortening prevention, and quicker sexual activity resumption. However, it still carries a high risk of complications like edema, infection, and distal perforations. Delayed inflatable penile prosthesis insertion poses surgical challenges due to the potential for extensive corporal fibrosis. Comparative analyses have shown elevated complication rates in patients with ischemic priapism who undergo delayed inflatable penile prosthesis insertion, as opposed to those with early insertion. In studies reporting complications rates, the total complication rate in the early group was 3.37%, significantly lower than the delayed group (37.23%). Most studies support the superiority of early inflatable penile prosthesis placement following ischemic priapism over delayed placement. Further research is, however, needed to establish a global consensus on timing of prosthesis insertion.

Does climate impact inflatable penile prosthesis infection (IPP) risk? Assessment of temperature and dew point on IPP infections.

BACKGROUND: Variations in climate have been associated with a greater risk of surgical site infections, urinary tract infections, and changes in the skin microbiome; however, limited data exist on the impact of climate on inflatable penile prosthesis (IPP) infections. AIM: We sought to evaluate the impact of climate on the risk of IPP infections in a large international, multicenter cohort. METHODS: We performed a multi-institutional, retrospective study of patients undergoing IPP surgery. We then evaluated whether the month or season, during which surgery was performed, affected device infections. Implant infections were defined as infections requiring device explantation. A univariate logistic regression analysis was undertaken. OUTCOMES: Our primary outcome was implant infection. RESULTS: A total of 5289 patients with a mean age of 62.2 ± 10.8 years received IPP placement. There was a fairly even distribution of implants performed in each season. A total of 103 (1.9%) infections were recorded. There were 32 (31.1%) IPP infections in patients who underwent surgery in the summer, followed by 28 (27.2%) in the winter, 26 (25.2%) in the spring, and 17 (16.5%) in the fall. No statistically significant differences were recorded in terms of season (P = .19) and month (P = .29). The mean daily temperature (P = .43), dew point (P = .43), and humidity (P = .92) at the time of IPP placement was not associated with infection. CLINICAL IMPLICATIONS: These findings provide reassurance to prosthetic urologists that infection reduction strategies do not need to be tailored to local climate. STRENGTHS AND LIMITATIONS: Climate data were not directly recorded for each hospital, but rather based on the monthly averages in the city where the surgery was performed. CONCLUSION: The climate at time of IPP placement and time of year of surgery is not associated with IPP infection risk.

The anterior transmuscular intrapelvic approach for the treatment of acetabular fractures-a new anterior surgical strategy.

The anterior ilioinguinal and the posterior Kocher-Langenbeck approach have long been the standard surgical approaches to the acetabulum. The last decade has witnessed the development of so-called intrapelvic approaches for anterior pathologies because they provide better exposure of the quadrilateral plate. Currently, the modified Stoppa approach and the pararectus approach are frequently used by surgeons for the treatment of acetabular fractures. We investigated an even more direct access to the entire anterior column and the quadrilateral plate via the abdominal wall muscles, between the incisions for the ilioinguinal and the pararectus approach.After intensive study of anatomic specimens, a cadaver dissection was performed prior to clinical application. The approach was then used in 20 patients who were assessed retrospectively.Postoperative CT scans showed that, according to the Matta scoring system, the quality of fracture reduction was "anatomical" (≤ 1 mm) in 12 (60%), "imperfect" (2-3 mm) in four (20%), and "poor" (> 3 mm) in four (20%) patients. Numerous minor complications were observed; the majority of these had resolved at the time of discharge.In conclusion, the anterior transmuscular intrapelvic approach (ATI) is a safe and effective alternative to the ilioinguinal and pararectal approaches, and may be regarded as an evolutionary advancement of traditional procedures.

Single Dilation in Primary Inflatable Penile Prosthesis Placement Is Associated With Fewer Corporal Complications Than Sequential Dilation.

OBJECTIVE: To assess the difference in outcomes between single dilation (SingD) and sequential dilation (SeqD) in primary penile implantation, hypothesizing that patients who undergo SeqD had higher rates of noninfectious complications. METHODS: We performed a multicenter, retrospective study of men undergoing primary inflatable penile prosthesis placement. Intraoperative complications and postoperative noninfectious outcomes were assessed between the two groups. Multivariable analysis was performed to identify predictors of complications. RESULTS: A total of 3293 patients met inclusion criteria. After matching, there were 379 patients who underwent SingD and 379 patients who underwent SeqD. There was no significant difference in intraoperative complications between patients who underwent SingD vs SeqD, nor was there any difference in cylinder length (20 cm with interquartile range [IQR] 18-21 cm vs 20 cm with IQR 18-20 cm respectively, P = .4). On multivariable analysis, SeqD (OR 5.23 with IQR 2.74-10, P < .001) and older age (OR 1.04 with IQR 1.01-1.06, P = .007) were predictive of postoperative noninfectious complications. There was no significant difference in intraoperative complications between patients who underwent SingD vs SeqD, nor was there any difference in cylinder length. SeqD and older age were predictive of postoperative noninfectious complications. CONCLUSION: During inflatable penile prosthesis placement in the uncomplicated patient without fibrosis, SingD is a safe technique to utilize during implantation that will minimize postoperative adverse events, and promote device longevity without loss of cylinder length.

Delayed placement of an inflatable penile prosthesis is associated with a high complication rate in men with a history of ischemic priapism.

BACKGROUND: Corporal fibrosis is known to result from prolonged priapism; however, the impact of the timing of penile prosthesis placement after priapism on complication rates is poorly understood. AIM: We sought to evaluate the impact of timing of inflatable penile prosthesis (IPP) placement on complications in men with a history of ischemic priapism. METHODS: We performed a multicenter, retrospective cohort study of patients with a history of priapism undergoing IPP placement by 10 experienced implantation surgeons. We defined early placement as ≤6 months from priapism to IPP. We identified a 1:1 propensity-matched group of men without a history of priapism and compared complication rates between men who had early placement, late placement, and no history of priapism. OUTCOMES: Our primary outcome was postoperative noninfectious complications, and secondary outcomes included intraoperative complications and postoperative infection. RESULTS: A total of 124 men were included in the study with a mean age of 50.3 ± 12.7 years. A total of 62 had a history of priapism and 62 were matched control subjects. The median duration of priapism was 37 (range, 3-168) hours and the median time from ischemic priapism to IPP placement was 15 months (range, 3 days to 23 years). Fifteen (24%) men underwent early (≤6 months) IPP placement at a median time of 2 months (range, 3 days to 6 months) following the ischemic priapism event. The remaining 47 (76%) underwent placement >6 months following priapism at a median time of 31.5 months (range, 7 months to 23 years). The complication rate in the delayed placement group was 40.5% compared with 0% in the early placement group and control group. Cylinder-related complications such as migration or leak accounted for 8 (57%) of 14 of the postoperative noninfectious complications. Full-sized cylinders were used in all patients who had a cylinder related complication. CLINICAL IMPLICATIONS: Priapism patients should be referred to prosthetic experts early to decrease complication rates in those needing an IPP. STRENGTHS AND LIMITATIONS: This is a multicenter study from experienced prosthetic urologists but is limited by the retrospective nature and small number of patients in the early placement group. CONCLUSION: IPP complication rates are high in men with a history of ischemic priapism, especially when implantation is delayed beyond 6 months.

Long-term assessment of the safety and effectivity of the mini-jupette sling: 5-year follow-up of the original series.

Background: In 2017, a prospective multicenter, multinational, investigational pilot study was conducted examining outcomes using a novel surgical technique, the Mini-Jupette sling, for the management of erectile dysfunction (ED) patients with climacturia and/or minimal stress urinary incontinence (SUI) after prostate procedures. Climacturia has been reported in up to 64% of patients following radical prostatectomy (RP). We sought to report the 5-year outcomes from this original cohort to assess long-term safety and effectivity of the mini-jupette sling in the treatment of ED and concomitant mild SUI and/or climacturia. Methods: This is a single-arm, multicenter, retrospective, observational study. We identified patients who were enrolled in the previous multicenter study with post-RP ED and climacturia and/or mild SUI- 2 PADS PER DAY (PPD) and underwent inflatable penile prosthesis (IPP) insertion with simultaneous placement of a mini-jupette sling. Data were collected including current PPD, subjective improvement in climacturia/SUI, complications, need for revision of IPP or additional urinary incontinence surgery, and date of most recent follow-up. SPSS was used for statistical analysis. Results: Of the original 38 patients, 5 have since died and 10 were lost to follow-up with 23/38 (61%) patients available for evaluation of long-term outcomes. The average follow-up time was 59 months (SD =8.8) with a mean age of 69 years (SD =6.8). Most patients (n=21, 91%) had subjective improvement of SUI and climacturia. One patient with persistent bothersome incontinence underwent artificial urinary sphincter (AUS) placement in 2018 with no complications, while the other is still considering a repeat procedure due to minor but persistent SUI. The mean PPD decreased from 1.4 preoperatively to 0.4 at a mean of 5 years of follow-up. Most patients reported satisfaction in their urinary symptoms with 91% and 73% reporting improvement in SUI and climacturia respectively, compared to 86% and 93% respectively in the original series. One (4.3%) patient had an IPP revision for pump malfunction. There were no device infections reported. Conclusions: The mini-jupette sling appears to be a safe and effective procedure with durable improvements in SUI and climacturia at 5 years of follow-up.

Combining PSA and PET features to select candidates for salvage lymph node dissection in recurrent prostate cancer.

Objective: To evaluate the relationship between pre-operative PSA value, 68Ga-prostate-specific-membrane-antigen (PSMA) PET performance and oncologic outcomes after salvage lymph node dissection (sLND) for biochemical recurrent prostate cancer (PCa). Patients and methods: The study included 164 patients diagnosed with ≤2 pelvic lymph-node recurrence(s) of PCa documented on 68Ga-PSMA PET scan and treated with pelvic ± retroperitoneal sLND at 11 high-volume centres between 2012 and 2019. Pathologic findings were correlated to PSA values at time of sLND, categorized in early (<0.5 ng/ml), low (0.5-0.99 ng/ml), moderate (1-1.5 ng/ml) and high (>1.5 ng/ml). Clinical recurrence (CR)-free survival after sLND was calculated using multivariable analyses and plotted over pre-operative PSA value. Results: Median [interquartile range (IQR)] PSA at sLND was 1.1 (0.6, 2.0) ng/ml, and 131 (80%) patients had one positive spot at PET scan. All patients received pelvic sLND, whereas 91 (55%) men received also retroperitoneal dissection. Median (IQR) number of node removed was 15 (6, 28). The rate of positive pathology increased as a function of pre-operative PSA value, with highest rates for patients with pre-operative PSA > 1.5 ng/ml (pelvic-only sLNDs: 84%; pelvic + retroperitoneal sLNDs: 90%). After sLND, PSA ≤ 0.3 ng/ml was detected in 67 (41%) men. On multivariable analyses, pre-operative PSA was associated with PSA response (p < 0.0001). There were 51 CRs after sLND. After adjusting for confounders, we found a significant, non-linear relationship between PSA level at sLND and the 12-month CR-free survival (p < 0.0001), with the highest probability of freedom from CR for patients who received sLND at PSA level ≥1 ng/ml. Conclusions: In case of PET-detected nodal recurrences amenable to sLND, salvage surgery was associated with the highest short-term oncologic outcomes when performed in men with PSA ≥ 1 ng/ml. Awaiting confirmatory data from prospective trials, these findings may help physicians to optimize the timing for 68Ga-PSMA PET in biochemical recurrent PCa.

AUA-recommended Antibiotic Prophylaxis for Primary Penile Implantation Results in a Higher, Not Lower, Risk for Postoperative Infection: A Multicenter Analysis.

PURPOSE: Our aim was to determine if the AUA-recommended prophylaxis (vancomycin + gentamicin alone) for primary inflatable penile prosthesis surgery is associated with a higher infection risk than nonstandard regimens. MATERIALS AND METHODS: We performed a multicenter, retrospective study of patients undergoing primary inflatable penile prosthesis surgery. Patients were divided into those receiving vancomycin + gentamicin alone and those receiving any other regimen. A Cox proportional-hazards model was constructed adjusted for major predictors. A subgroup analysis to identify the appropriate dosage of gentamicin was also performed. RESULTS: A total of 4,161 patients underwent primary inflatable penile prosthesis placement (2,411 received vancomycin + gentamicin alone and 1,750 received other regimens). The infection rate was similar between groups, 1% vs 1.2% for standard vs nonstandard prophylaxis. In the multivariable analysis, vancomycin + gentamicin (HR: 2.7, 95% CI: 1.4 to 5.4, P = .004) and diabetes (HR: 1.9, 95% CI: 1.03 to 3.4, P = .04) were significantly associated with a higher risk of infection. Antifungals (HR: 0.08, 95% CI: 0.03 to 0.19, P < .001) were associated with lower risk of infection. There was no statistically significant difference in infection rate between weight-based gentamicin compared to 80 mg gentamicin (HR: 2.9, 95% CI: 0.83 to 10, P = .1). CONCLUSIONS: Vancomycin + gentamicin alone for antibiotic prophylaxis for primary inflatable penile prosthesis surgery is associated with a higher infection risk than nonstandard antibiotic regimens while antifungal use is associated with lower infection risk. A critical review of the recommended antimicrobial prophylactic regimens is needed. Prospective research is needed to further elucidate best practices in inflatable penile prosthesis antimicrobial prophylaxis.

[Cystectomy of a young patient with squamous cell metaplasia of the bladder and manifestation of condyloma]. / Zystektomie einer jungen Patientin mit verhornter plattenepithlialen Metaplasie der Harnblase und ausgeprägtem Kondylombefall.

Interdisciplinary managed case of a 29-Year-old patient with massive condylomas of the vulva and papillary squamous cell metaplasia of the bladder, leads after years of chronic cystitis and obstruction with meatus plastic and laser treatment to cystectomy with conduit and partial vulvectomy. After long lasting HPV infection with condyloma we also found a squamous cell carcinoma (pT1 G1) of the vulva.

Impact of Surgical Experience Before Robot-assisted Partial Nephrectomy on Surgical Outcomes: A Multicenter Analysis of 2500 Patients.

Background: Robot-assisted partial nephrectomy (RAPN) is a challenging procedure that is influenced by a multitude of factors. Objective: To assess the impact of prior surgical experience on perioperative outcomes in RAPN. Design setting and participants: In this retrospective multicenter study, results for 2548 RAPNs performed by 25 surgeons at eight robotic referral centers were analyzed. Perioperative data for all consecutive RAPNs from the start of each individual surgeon's experience were collected, as well as the number of prior open or laparoscopic kidney surgeries, pelvic surgeries (open, laparoscopic, robotic), and other robotic interventions. Intervention: Transperitoneal or retroperitoneal RAPN. Outcome measurements and statistical analysis: The impact of prior surgical experience on operative time, warm ischemia time (WIT), major complications, and margin, ischemia, complication (MIC) score (negative surgical margins, WIT ≤20 min, no major complications) was assessed via univariate and multivariable regression analyses accounting for age, gender, body mass index (BMI), American Society of Anesthesiologists score, PADUA score, and RAPN experience. Results and limitations: BMI, PADUA score, and surgical experience in RAPN had a strong impact on perioperative outcomes. A plateau effect for the learning curve was not observed. Prior laparoscopic kidney surgery significantly reduced the operative time (p < 0.001) and WIT (p < 0.001) and improved the MIC rate (p = 0.022). A greater number of prior robotic pelvic interventions decreased WIT (p = 0.011) and the rate of major complications (p < 0.001) and increased the MIC rate (p = 0.011), while prior experience in open kidney surgery did not. One limitation is the short-term follow-up. Conclusions: Mastering of RAPN is an ongoing learning process. However, prior experience in laparoscopic kidney and robot-assisted pelvic surgery seems to improve perioperative outcomes for surgeons when starting with RAPN, while experience in open surgery might not be crucial. Patient summary: In this multicenter analysis, we found that a high degree of experience in keyhole kidney surgery and robot-assisted pelvic surgery helps surgeons in achieving good initial outcomes when starting robot-assisted kidney surgery.

Pre- and intratherapeutic predictors of overall survival in patients with advanced metastasized castration-resistant prostate cancer receiving Lu-177-PSMA-617 radioligand therapy.

BACKGROUND: Systemic Lutetium-177 prostate-specific membrane antigen-617 radioligand therapy (Lu-177-PSMA-617-RLT) is a novel treatment approach in patients suffering from metastasized castration-resistant prostate cancer. Nonetheless, a therapeutic response may fail to appear in a proportion of patients. This study aims to identify routinely obtainable pre- and intratherapeutic parameters to allow a prediction of overall survival in patients receiving Lu-177-PSMA-617 radioligand therapy. METHODS: Between January 2015 and December 2020 52 patients treated with a total of 146 cycles Lu-177-PSMA-617-RLT were retrospectively analysed in a single-center trial. The median overall survival time (OS) was compared to pre-therapeutic serological parameters, the extend of metastatic spread and previously performed therapies using Kaplan-Meier estimators and multivariate Cox-regression. Bonferroni-Holm correction was performed on all statistical tests. RESULTS: The median OS of all patients was 55.6 weeks. Multivariate Cox-regression revealed significant lower survival for decreased pretherapeutic hemoglobin levels (HR 0.698 per g/dl; 95%-CI 0.560-0.872; p = 0.001), increased lactate dehydrogenase (LDH) levels (HR 1.073 per 25 U/l; 95%-CI 1.024-1.125; p = 0.003) and the presence of hepatic metastasis (HR 6.981; 95%-CI 2.583-18.863; p < 0.001). Increased pretherapeutic c-reactive protein (CRP), alkaline phosphatase (ALP) and gamma-glutamyltransferase (GGT) levels were also associated with a shorter survival. A prostate-specific antigen decline after one therapy cycle did not significantly correlate with an increased survival. No significant relations were observed between overall survival time and other serological parameters or previously performed therapies. CONCLUSION: Pre-therapeutic hemoglobin and LDH levels, as well as the presence of hepatic metastasis are independent predictors of overall survival in patients receiving Lu-177-PSMA-617-RLT. CRP, ALP and GGT levels cloud be utilized as additional decision aids when a Lu-177-PSMA-617-RLT is intended. Trial Registration Not applicable (retrospective observational study).

The International Penile Prosthesis Implant Consensus Forum: clinical recommendations and surgical principles on the inflatable 3-piece penile prosthesis implant.

Despite significant scientific advances in the modern three-piece inflatable penile prosthesis implant surgery, it is not without surgical risks and can carry additional cosmetic and psychosocial consequences in poorly selected and consented individuals. To address this problem, an international group of key opinion leaders and high-volume prosthetic surgeons reviewed the current guidelines and clinical evidence, discussed their experiences, and formed a consensus regarding inflatable penile prosthesis surgery. The findings of this consensus panel were presented at the 17th biennial Asia Pacific Society of Sexual Medicine scientific meeting. The experts concluded that proper patient selection, informed consent and strict adherence to safe surgical principles are important to optimize clinical outcomes. Furthermore, most intraoperative complications, if recognized, can be addressed intraoperatively to enable placement of the device at the time of initial surgery. Men with significant corporal fibrosis due to Peyronie's disease, prior prosthesis explantation and priapism, and men who have undergone construction of a neophallus, as well as men who receive concurrent continence surgery, are complex cases requiring additional care and advanced techniques to obtain optimal surgical outcomes. Variability in patient care - in terms of postoperative antibiotic use, pain management, scrotal care, and cycling of the penile prosthesis implant - must be reduced to enable optimization and assessment of outcomes across patient groups.

Evaluation of the Versius Robotic Surgical System for Procedures in Small Cavities.

BACKGROUND: The Versius® is a recently approved robotic surgical system for general surgery procedures in adults. Before any application in children, data of its feasibility and safety in small cavities has to be compiled, beginning with inanimate models. Therefore, the aim of this preclinical study was to assess the Versius® system for its performance in small boxes simulating small body cavities. METHODS: In total, 8 cardboard boxes of decreasing volumes (15.75 L to 106 mL) were used. The procedures, two single stitches with two square knots each, were performed in every box, starting in the largest and consecutively exchanging the box to the next smaller one. The evaluation included procedure time, port placement and pivot point setup, arrangement of the robotic arms and instrumentation, amount of internal and external instrument-instrument collisions and instrument-box collisions. RESULTS: All procedures could be successfully performed in all boxes. The procedure time decreased due to the learning curve in the first four boxes (15.75 to 1.87 L) and consecutively increased from boxes of 1.22 L up to the smallest box with the dimensions of 4.4 × 4.9 × 4.9 cm3. This may be based on the progress of complexity of the procedures in small cavities, which is also depicted by the synchronous increase of the internal instrument-instrument and instrument-box collisions. CONCLUSION: With the use of the Versius® robotic surgical system, we were able to perform robotic reconstructive procedures, such as intracorporal suturing and knot tying, in cavities as small as 106 mL. Whether this system is comparable or even superior to conventional laparoscopic surgery in small cavities, such as in children, has to be evaluated. Furthermore, before any application in newborns or infants, ongoing evaluation of this system should be performed in a live animal model.

[Evaluation of the Padua and R.E.N.A.L. scores regarding their validity and implication in the perioperative management during partial nephrectomy]. / Evaluation von Padua- und R.E.N.A.L.-Score hinsichtlich ihrer Aussagekraft und Implikationen auf das perioperative Management bei der partiellen Nephrektomie.

BACKGROUND: Due to the rapid development of minimally-invasive surgery, there is a broader indication for surgical preservation of renal tissue. Current research suggests that, apart from the size of the tumour, its exact anatomical position should be considered when seeking optimal surgical treatment for individual patients. Therefore, numerous nephrometry scores have emerged, the Padua score and the R.E.N.A.L. score being most commonly used. Based on our patient population, we aimed to shed light on the question which score is best suited to assess the feasibility of nephron-sparing surgery and which can predict complications most accurately. PATIENTS AND METHODS: This study included 117 patients treated with partial nephrectomy at the University Hospital in Kiel (UKSH, Campus Kiel) between 2014 and 2017. The imaging results (computed tomography and magnetic resonance tomography) were retrospectively evaluated according to the Padua and R.E.N.A.L. score criteria. In some cases, radical nephrectomy became necessary despite the planned partial nephrectomy. We evaluated group differences regarding both nephrometry scores in these cases and the cases without radical nephrectomy. Then we performed correlation analyses regarding score outcome, operation time as well as perioperative, postoperative and overall complications. RESULTS: The tumours requiring treatment by radical nephrectomy (10 out of 117) had significantly higher scores only when the R.E.N.A.L. score was applied (mean difference 1.059, p < 0.05). Both the Padua and the R.E.N.A.L. score were positive correlated with operation time (R.E.N.A.L. score: correlation coefficient 0.284, p < 0.05, Padua score: coefficient 0.312, p < 0.05) as well as perioperative, postoperative and overall complications (R.E.N.A.L. score: coefficient 0.216, p < 0.05, Padua score: coefficient 0.192, p < 0.05). CONCLUSION: Each of the examined scores can be used to assess the risk of partial nephrectomy. For our patients, the preoperative application of the R.E.N.A.L. score would have been advantageous. Preoperative nephrometry scores are a useful tool and should be applied in addition to the surgeon's subjective evaluation. There is a lack of prospective studies investigating this issue.

[Side-specific correlation between tumor location determined by biopsy and HistoScanning and nodal metastases in prostate cancer]. / Zusammenhang zwischen der seitenabhängigen präoperativ bestimmten intraprostatischen Tumorlokalisation mittels Stanzbiopsie und HistoScanning und der Lymphknotenmetastasierung des Prostatakarzinoms.

INTRODUCTION: This study investigates whether it is possible to predict the side of lymph node metastasis in prostate cancer preoperatively by evaluating biopsy or HistoScanning results. MATERIAL: This is a retrospective study including 56 patients. Prostatectomy, extended lymphadenectomy and lymph node metastasis were chosen as inclusion criteria. We analysed the relation between the preoperatively determined side of the tumour in the prostate and the side of pelvic lymph node metastases. METHODS: Microsoft® Office 365 Excel and IBM® SPSS® Statistics Subscription were used as statistic tools. For the statistical analysis, the Fisher exact test was employed. P values of < 0.05 were rated as statistically significant. RESULTS: A significant correlation between the location of the tumour in the prostate determined by biopsy and the side of lymph node metastasis has been shown. A share of 83 % of all patients with unilateral prostate cancer diagnosed by biopsy have lymph node metastases on one side (ipsilateral or contralateral); 75 % of those patients have exclusively ipsilateral metastases. The results of using HistoScanning as a diagnostic instrument are not convincing. The histopathological analysis after prostatectomy showed tumour growth in both prostate lobes in 89 % of the patients. CONCLUSION: Both biopsy and HistoScanning seem to underestimate the tumour spread in the prostate. Due to this inaccuracy, a recommendation to restrict lymphadenectomy to one side cannot be given although some significant correlation has been found.

Current practices regarding corporotomy localization during penoscrotal inflatable penile implant surgery: a multicenter cohort study.

Literature concerning corporotomy location in multicomponent inflatable penile prosthetic surgery via a penoscrotal approach is scarce if not nonexistent. Aim of our study was to report practices in low-, moderate-, and high-volume penile implant centers regarding corporotomy location and evaluate its potential impact on intraoperative and short-term postoperative complications. Data from 18 (13 European and 5 American) implant centers were collected retrospectively between September 1st, 2018 and August 31st, 2019. Variables included: intraoperative proximal and distal corpus cavernosum length measurement, total corporal length measurement, total penile implant cylinder length, and length of rear tip extenders. Eight hundred and nine virgin penile implant cases were included in the analysis. Mean age of participants was 61.5 ± 9.6 years old. In total, 299 AMS 700™ (Boston Scientific, USA) and 510 Coloplast Titan® (Minneapolis, MN USA) devices were implanted. The mean proximal/distal corporal measurement ratio during corporotomy was 0.93 ± 0.29 while no statistical difference was found among low-, moderate-, and high-volume penile implant centers. A statistically significant correlation between lower proximal/distal measurement ratio and higher age (p = 0.0013), lower BMI (p < 0.0001), lower use of rear tip extenders (RTE) (p = 0.04), lower RTE length (p < 0.0001), and absence of diabetes (p = 0.0004) was reported. In a 3-month follow up period, 49 complications and 37 revision procedures were reported. This is the first study reporting the current practices regarding corporotomy location during IPP placement in a multicenter cohort, particularly when including such a high number of patients. Nevertheless, the retrospective design and the short follow up period limits the study outcomes. Corporotomy location during penoscrotal IPP implantation does not correlate with intraoperative or short-term postoperative complication rates. Future studies with longer follow up are needed in order to evaluate the association of corporotomy location with long-term complications.

Definition and Impact on Oncologic Outcomes of Persistently Elevated Prostate-specific Antigen After Salvage Lymph Node Dissection for Node-only Recurrent Prostate Cancer After Radical Prostatectomy: Clinical Implications for Multimodal Therapy.

BACKGROUND: The optimal definition and prognostic significance of persistently elevated prostate-specific antigen (PSA) after salvage lymph node dissection (sLND) for node-only recurrent prostate cancer (PCa) remain unknown. OBJECTIVE: To assess the definition and clinical implications of persistently elevated PSA after sLND for node-only recurrent PCa after radical prostatectomy. DESIGN, SETTING, AND PARTICIPANTS: The study included 579 patients treated with sLND at 11 high-volume centers between 2000 and 2016. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We assessed the linear relationship between the first PSA after sLND and death from PCa. Different definitions of PSA persistence were included in a multivariable model predicting cancer-specific mortality (CSM) after surgery to identify the best cutoff value. We investigated the association between PSA persistence and oncologic outcomes using multivariable regression models. Moreover, the effect of early androgen deprivation therapy (ADT) after sLND was tested according to PSA persistence status and estimated risk of CSM. RESULTS AND LIMITATIONS: We found an inverse relationship between the first PSA after sLND and the probability of cancer-specific survival. PSA persistence defined as first postoperative PSA ≥0.3 ng/ml provided the best discrimination accuracy (C index 0.757). According to this cutoff, 331 patients (57%) experienced PSA persistence. The median follow-up for survivors was 48 mo (interquartile range 27-74). After adjusting for confounders, men with persistently elevated PSA had higher risk of clinical recurrence (hazard ratio [HR] 1.61), overall mortality (HR 2.20), and CSM (HR 2.59; all p < 0.001) after sLND. Early ADT administration after sLND improved survival only for patients with PSA persistence after surgery (HR 0.49; p = 0.024). Similarly, when PSA persistence status was included in multivariable models accounting for pathologic features, early ADT use after sLND was beneficial only for patients with a predicted risk of CSM at 5 yr of >10%. CONCLUSIONS: PSA persistence after sLND independently predicts adverse prognosis, with the best discrimination accuracy for CSM provided by a definition of PSA ≥ 0.3 ng/ml. We showed that when stratifying patients by final pathology results and PSA persistence status, early ADT use after sLND was beneficial only for patients with PSA persistence or with a calculated 5-yr risk of CSM of >10%, which could be useful as we await results from ongoing prospective trials. PATIENT SUMMARY: We found that for patients with prostate cancer who had lymph nodes removed after their cancer recurred, persistently elevated prostate-specific antigen (PSA) levels predict poorer prognosis. We showed that a PSA level of ≥0.3 ng/ml provides the best accuracy in identifying patients with worse prognosis. This may help to improve risk stratification after lymph node removal and allow physicians to optimize treatment strategies after surgery.

Laparoscopic varicocelectomy in male infertility : Improvement of seminal parameters and effects on spermatogenesis.

BACKGROUND: The suitability of laparoscopic varicocelectomy for assisted reproductive technology depends on the improvement of semen parameters. The present study analyzed the improvement of semen parameters following laparoscopic varicocele ligation. MATERIAL AND METHODS: A retrospective study of the laparoscopic varicocele clippings at the Department of Urology of University Hospital of Kiel between the years 2007 and 2019 was conducted. The semen analyses according to WHO standards (sperm count, density, motility and morphology) were conducted before and 12 months after surgery. Screening for surgical complications took place at the time of the follow-up seminal analysis. Included were patients with oligozoospermia, asthenozoospermia and/or teratozoospermia (group 1, OAT) or with nonobstructive azoospermia (group 2, NOA). RESULTS: This study included data of 27 patients and 22 patients presented preoperative OAT (81%, group 1). Another 5 patients showed NOA (19%, group 2). Data of group 1 showed that semen parameters normalized in 32% of the patients after surgery. Significant improvement in total sperm count (p < 0.005), sperm density (p < 0.005) and total motile sperm count (p < 0.005) was observed. No deterioration of semen parameters was observed. In group 2 we detected spermatozoa in 1 case in the postoperative ejaculate. None of the patients showed complications according to the Clavien-Dindo classification, postoperative hydrocele formation or recurrence of varicocele at the time of control spermiogram. CONCLUSION: Laparoscopic varicocelectomy is a valid therapeutic approach to improve semen parameters for further assisted reproductive techniques. Spermatogenesis may be induced for patients with NOA. Normalization of semen parameters can be achieved for patients with OAT.

ESSM Position Statement on Surgical Treatment of Peyronie's Disease.

INTRODUCTION: Patients with Peyronie's disease may experience significat distress. The choice of treatment depends on a variety of factors, including the stage of the disease, the presence of pain, severity and direction of the curvature, penile length and the quality of erectile function. AIM: To review the evidence associated with surgical treatment of Peyronie`s Disease and provide clinical recommendations on behalf of the European Society for Sexual Medicine. 131 peer-reviewed studies and systematic reviews, which were published from 2009 to 2019 in the English language, were included. METHODS: MEDLINE, Google Scholar and EMBASE were searched for randomized clinical trials, meta-analyses, open-label prospective and retrospective studies. MAIN OUTCOME MEASURE: The panel provided statements on clinically relevant questions including patient involvement in the decision process, indications for surgery, choice of the approach, and the management of patient expectations. A comparison of the different grafts used in patients who have undergone plaque incision/excision and grafting in order to identify an ideal graft, has been carried out. The prevalence of postoperative complications has been summarized. Levels of evidence were provided according to the Oxford 2011 criteria and Oxford Centre for Evidence-Based Medicine recommendations. RESULTS: In order to allow shared decision making, a patient preoperative counselling regarding the pros and cons of each intervention is recommended. In particular, adverse effects of surgical treatments should be discussed to set realistic understanding and expectations of surgical outcomes and ultimately improve postoperative satisfaction rates. Surgical treatment should be only offered in the chronic phase of the condition, when the deformity and/or degree of erectile dysfunction, prevent patients from engaging in satisfying sexual interaction, or if the deformity is the cause of severe bother. CONCLUSIONS: Current European Society for Sexual Medicine recommendations cover several aspects of Peyronie's disease treatment. These recommendations aim both to ensure patients and partners have accurate and realistic expectations of their treatment options, as well as to formulate algorithms to guide clinician management pathways.

Preputioplasty as a surgical alternative in treatment of phimosis.

Preputioplasty denotes various surgical techniques directed at resolving phimosis without the need for radical or partial circumcision. This narrative review summarizes the best-known surgical techniques of preputioplasty. A MEDLINE and EMBASE-based literature search of original manuscripts and case reports published in English has been carried out using the following key words: "circumcision", "partial circumcision", "phimosis", "paraphimosis", and "preputioplasty". Six different procedures are explored in more detail and illustrated. The complication rates of all surgical procedures presented here are reported to be low. In cases of medical (rather than cultural and religious) indications, foreskin-preserving procedures present useful alternatives to circumcision in the routine clinical practice of urologists and pediatric surgeons.
