RESUMO
Solid organ transplant recipients exhibit an elevated incidence of erectile dysfunction, attributed to comorbidities and specific factors associated with organ failure. While treatment mirrors the general population's, response rates are lower, and there is a heightened concern about implanting a penile prosthesis in immunocompromised patients due to the potential occurrence of severe complications. The aim of this study was to assess the safety of penile prostheses in this population. Among fourteen included studies, ten were case reports or series of cases, and four were non randomized case-control studies with non-transplanted patients as controls. Complications affected 34 patients (11.15%), with mechanical device failures in 18 cases (5.9%) and infections in 13 cases (4.26%). Most infections required hospitalization, antibiotic treatment, and prosthesis removal, with two cases of life-threatening Fournier's gangrene. Case-control studies revealed no differences in overall reoperation rates between transplant recipients and controls. However, pelvic organ transplant recipients undergoing three-piece prosthesis implantation showed higher complications rates related to reservoir issues. Despite limited evidence, case-control studies demonstrated a generally low/moderate risk of bias within each specific domain, although overall bias was moderate/severe. As a result, clinicians may mitigate concerns regarding penile prosthesis implantation in solid organ transplant recipients.
RESUMO
Undescended testis (UDT, cryptorchidism) is the most frequent genital anomaly in boys. However, its treatment varies widely throughout the world. This second part of our roundtable discussion aims to continue to ask global experts to express their attitudes towards several case scenarios of UDT in order to explore the rationale for their clinical decisions. As the European Association of Urology - Young Academic Urologists Pediatric Urology Working Group, we believe that this roundtable series will facilitate colleagues all over the world to reflect and improve their practices regarding the treatment of UDT.
RESUMO
BACKGROUND: Current potential living kidney donor's assessment includes functional and anatomical evaluation. Scintigraphy is recommended in some cases and some centers include this test in the donor's protocol. Recent studies advocate for the avoidance of this test as CT or MRI volumetry showed to accurately assess donor's renal function. OBJECTIVE: To summarize scientific evidence on image tests for pre-donation and/or post-nephrectomy renal function evaluation. EVIDENCE ACQUISITION: This review followed the guidelines set by the European Association of Urology and adhered to PRISMA 2020 recommendations. The protocol was registered in PROSPERO on 10th December 2022 (ID: CRD42022379273). EVIDENCE SYNTHESIS: Twenty-one studies met the inclusion criteria after thorough screening and eligibility assessment. According to QUADAS-2, patient selection and flow/timing domains showed a predominant low risk of bias. The correlation between split renal function (SRF) using CT and scintigraphy varied from weak (r = 0.21) to remarkably strong (r = 0.949). Bland-Altman agreement demonstrated moderate to excellent results, with mean differences ranging from -0.06% to 1.76%. The correlation between split renal volume (CT) and estimated glomerular filtration rate (eGFR) at 6 months or 1 year after nephrectomy showed a moderate correlation, with coefficients ranging from 0.708 to 0.83. The correlation between SRF (MRI) and renal scintigraphy reported a moderate correlation, with correlation coefficients of 0.58 and 0.84. MRI and scintigraphy displayed a good agreement, with a 66% agreement observed and mean differences of ± 0.3%. CONCLUSIONS: Despite study heterogeneity, MRI or CT-based renal volumetry appears promising compared to scintigraphy, with favorable correlations and agreement.

OBJECTIVE: To conduct a systematic review (SR) of literature to assess the existing evidence concerning the success and complications of endourological ex vivo stone surgeries. METHODS: Eligible studies for inclusion focused on investigating the success and/or complications related to endourological ex vivo surgeries in donors with nephrolithiasis. A SR was undertaken in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search included databases of Web of Science, PubMed, and Scopus and only article in English were included. Studies published between 2002 and 2023 included in this SR. RESULTS: After screening 1726 abstracts, this SR included 16 studies with a total of 209 patients. The mean stone size was 5.6 mm and majority of kidneys contained single stones, located in the lower calyx. After ex vivo endourological stone surgeries, the average stone-free rate was found to be 95.4%. The mean duration of ex vivo surgery was 17.3 minutes. Regarding intraoperative complications, two patients (1%) experienced mucosal injuries during pneumatic lithotripsy. As for postoperative complications, two patients (1%) experienced vascular complications. In terms of urological complications, hematuria was observed in 24 patients (11.5%), while one patient (0.5%) experienced clot formation in renal pelvis. Seven patients (3.3%) had urinary tract infections, and three patients (1.4%) developed urolithiasis during the follow-up. Additionally, one patient (0.5%) experienced complete occlusion of ureteroneocystostomy and required revision. CONCLUSION: Given the advancements in current technology and techniques, endourological ex vivo stone surgeries are increasingly recognized as an effective and safe option for donors with nephrolithiasis. TRIAL REGISTRATION: This systematic review was registered under the protocol registration number CRD42024538384/PROSPERO.
RESUMO
PURPOSE: Patients with lower urinary tract malformations (LUTM) were suspended from kidney transplantation (KT) programs in the past due to various concerns. Consequently, only a limited number of studies have explored this topic at hand. In this study, our objective was to perform a systematic review (SR) to evaluate the current evidence regarding KT outcomes as well as patient survival (PS), postoperative complications and urinary tract infections (UTI) in individuals with childhood LUTM. METHODS: The search encompassed databases of Web of Science, Medline (via PubMed), and Embase (via Scopus) to identify all studies reporting outcomes on KT for patients with LUTM. The research included articles published in English from January 1995 till September 2023. RESULTS: Of the 2634 yielded articles, 15 met the inclusion criteria, enrolling a total of 284,866 KT patients. There was significantly better 5-year graft survival (GS) in recipients with LUTM compared to the control group (RR, 1.04; 95% CI 1.02-1.06); while GS at 1-year and 10-year, and PS at 1-year, 5-year and 10-year were similar between groups. On the other hand, the postoperative UTI rate was significantly higher in the LUTM group (RR: 4.46; 95% CI 1.89-10.51). However, data on serum creatinine and estimated glomerular filtration rate on follow-up were insufficient. CONCLUSION: GS and PS rates appear to be similar in patients with childhood LUTM and those with normal lower urinary tract functions. Despite a higher postoperative UTI rate within this patient group, it appears that this has no effect on GS rates.
RESUMO
Standardized training programs for open (OKT) and robot-assisted kidney transplantation (RAKT) remain unmet clinical needs. To fill this gap, we designed a modified Delphi Consensus aiming to propose the first structured surgical curricula for both OKT and RAKT, involving a multispecialty international panel of experts. Two web-based surveys were built drafting two separate series of statements (for OKT and RAKT, respectively). The two surveys were delivered to a panel of 63 experts (for OKT) and 21 experts (for RAKT), selected considering their experience, academic profile and involvement in international associations. Consensus was defined as ≥75% agreement between the responders. Overall, 25/63 (40%) and 14/21 (67%) participated in the first round of the Delphi Consensus for the development of the structured curriculum for OKT and RAKT, respectively. During the second round, the experts reached consensus on all statements, as well as on the domains composing the structure of the training pathway: 1) eligibility criteria for trainees and host centres; 2) theoretical training; 3) simulation; 4) real case observation; and 5) modular training in the operating theatre. To the best of our knowledge, this is the first proposal of a dedicated curriculum for OKT and RAKT grounded on insights from international experts of different specialties. Our proposed curriculum provides the foundation to standardize the education and training in KT across Europe and beyond.

Undescended testis (UDT, cryptorchidism) is the most common congenital anomaly of the genital tract. Despite its high incidence, the management of UDT varies between specialties (urology, pediatric surgery, pediatric urology, pediatric endocrinology). Therefore, as the European Association of Urology - Young Academic Urologists Pediatric Urology Working Group, we requested experts around the world to express their own personal approaches against various case scenarios of UDT in order to explore their individual reasoning. We intended to broaden the perspectives of our colleagues who deal with the treatment of this frequent genital malformation.

OBJECTIVE: To evaluate strategies that are followed after pediatric renal trauma during the recovery stage, with an emphasis on mobility and involvement in subsequent sporting activities. Renal trauma is the most common urogenital trauma in children. The American Association for the Surgery of Trauma (AAST) scale is most commonly used to stratify the severity of injury. There is no consensus in the existing literature with respect to the recovery stage following renal trauma. METHODS: A survey was constructed by the European Association of Urology (EAU) - Young Academic Urologists (YAU) Pediatric Urology Working Group and then made digitally available on SurveyMonkey. The survey consists of 15 questions exploring relevant factors and timing to start again with mobility and activity. RESULTS: In total 153 people responded, of whom 107 completed the entire survey. The presence of pain and severity of trauma were acknowledged as most important factors to commence mobilization, whereas presence of hematuria was identified as an additional factor for sporting activity. Regardless of severity of trauma a minimum of 90% of respondents recommend return to noncontact sports within 12weeks. For contact sports, a minimum of 33% of respondents advised >12weeks minimum before starting again. A small number of respondents would never allow sporting activities again. CONCLUSION: The time to allow sporting activity shows high variation among the respondents, some even restricting sporting activities completely. This survey highlights the need for a standardized protocol based on multicenter follow-up data.

INTRODUCTION: Traditionally, open ureteral reimplantation (OUR) has been the standard treatment for primary vesicoureteral reflux (VUR) requiring reimplantation. Robotic-assisted laparoscopic ureteral reimplantation (RALUR) is gaining popularity and high success rates have been reported. OBJECTIVE: In this multi-institutional study, we aimed to compare the perioperative and postoperative outcomes of OUR and RALUR for high-grade (IV + V) VUR in children. STUDY DESIGN: A retrospective evaluation was performed collecting data from 135 children (0-18 years) who underwent high grade VUR surgical correction at nine European institutions between 01/01/2009 and 01/12/2020, involving either open or robotic approaches. Institutional review board approval was obtained. Patients with lower grades of VUR (≤III), previous history of open or endoscopic ureteral surgery, neurogenic bladder, or refluxing megaureter in need of ureteral tapering were excluded. Pre-, peri- and post-operative data were statistically compared. RESULTS: Overall, 135 children who underwent either OUR (n = 68), or RALUR (n = 67) were included, and their clinic and demographic features were collected. The mean age of the open group was 11 months (interquartile range [IQR] 9.9-16.6 months), in the RALUR group it was 59 months (IQR 29-78mo) (p < 0.01); the open cohort had a weight of 11 kg (IQR 9.9-16.6 kg) while the RALUR group had 19 kg (IQR 13-25 kg) (p < 0.01). No significant differences were found for intraoperative (1.5 % vs 7.5 %, p = 0.09) or for postoperative complication rates (7.4 % vs 9 %, p = 0.15). Favorable outcomes were reported in the RALUR group: shorter time to stooling (1 vs 2 days), fewer indwelling urethral catheter days (1 vs 5 days), perioperative drain insertion time (1 vs 5 days) and a shorter length of hospital stay (2 vs 5 days) (p < 0.01). The success rate was 94.0 % and 98.5 % in the open and RALUR groups, respectively. The long-term clinical success rates from both groups was comparable:42 vs 23 months for open and RALUR, respectively. DISCUSSION: This study reported a large multicentric experience focusing on high grade VUR. Furthermore, this study compares favorably to OUR in a safety analysis. There was also a trend towards higher success rates with RALUR utilizing an extravesical approach which has not been previously reported. CONCLUSION: RALUR is an efficacious and safe platform to use during ureteral reimplantation for high grade VUR. The overall peri-operative and post-operative complication rates are at least equivalent to OUR, but it is associated with a faster functional recovery and time to discharge. Medium to long term success rates are also equivalent to OUR.
RESUMO
The iliac fossa is the most commonly used site to place the graft in renal transplantation in adults. However, iliac fossa may not be used in various conditions. Thus, orthotopic renal transplantation becomes a viable alternative for these selected patients. Given the technically challenging surgery and limited number of patients, data on the long-term outcomes on this regard are scarce. This narrative review serves as an update on the clinical outcomes after orthotopic renal transplantation, focusing on overall recipient survival and renal graft survival, as well as postoperative complications. We found that studies to date showed a comparable survival rate in both recipients and renal grafts in the postoperative follow-up period after orthotopic renal transplantation with a lower complication rate compared to the published data on heterotopic renal transplantation. The results of our review may encourage transplant centers to reevaluate their policies to consider orthotopic renal transplantation as an alternative technique in cases where heterotopic kidney transplantation is not possible.

Robot-assisted radical prostatectomy (RARP) has been shown to achieve excellent oncological outcomes with a low rate of complications in patients with prostate cancer. However, data on RARP in renal transplant recipients (RT) are dispersed. A literature search was conducted through April 2023 using PubMed/Medline, Embase and Web of Science databases. The primary aim was to evaluate the safety, oncologic and clinical outcomes of RARP in RT recipients. The secondary aim was to identify surgical technique modifications required to avoid iatrogenic damage to the transplanted kidney. A total of 18 studies comprising 186 patients met the inclusion criteria. Age at the time of treatment ranged 43-79 years. Biopsy results showed a high prevalence of low- and intermediate-risk disease. Operative time ranged between 108.3 and 400 mins, while estimated blood loss ranged from 30 to 630 mL. Length of hospital stay ranged from 3 to 6 days whereas duration of catheterization was between 5 and 18 days. Perioperative complication rate was 17.1%. Overall positive surgical margin rate was 24.19%, while biochemical recurrence was observed in 10.21% (19/186 patients). Modifications to the standard surgical technique were described in 13/18 studies. Modifications in port placement were described in 7/13 studies and performed in 19/88 (21.6%) patients. Surgical technique for the development of the Retzius space was reported in 13/18 studies. Data on lymphadenectomy were reported in 15/18 studies. Bilateral lymphadenectomy was described in 3/18 studies and performed in 4/89 (4.5%) patients; contralateral lymphadenectomy was reported in 7/18 studies and performed in 41/125 (32.8%) patients. RARP in RTRs can be considered relatively safe and feasible. Oncological results yielded significantly worse outcomes in terms of PSM and BCR rate compared to the data available in the published studies, with an overall complication rate highly variable among the studies included. On the other hand, low graft damage during the procedure was observed. Main criticisms came from different tumor screening protocols and scarce information about lymphadenectomy techniques and outcomes among the included studies.
RESUMO
Background: The term glass ceiling coined by Loden in 1978 is commonly used to describe difficulties faced by minorities and women when trying to move into senior roles. Objective: To analyse trends and patterns for female representation at the European Association of Urology (EAU) and European Society for Paediatric Urology (ESPU) annual general meetings over the past decade. Design setting and participants: We used objective data on female representation in the roles of chairs, moderators, and lecture speakers at the EAU and ESPU meetings from 2012 to 2022. Outcome measurements and statistical analysis: We evaluated gender based representation in paediatric urology sessions at the EAU and ESPU meetings, collecting data on the overall number of sessions, lectures, symposiums, abstract/poster sessions, and courses, and analysed the male/female ratio. Data were derived from printed and digital programmes for the relevant meetings. Results and limitations: During the period from 2012 to 2022, the percentage female representation varied from 0% (2012) to a maximum of 35% (2022) at EUA paediatric urology sessions, and from 13.5% (2014) to a maximum of 32% (2022) at ESPU meetings. Both associations show clear progression towards equality. Conclusions: Female representation at EAU and ESPU meetings has risen over the years, reaching 35% and 32%, respectively, in 2022, which is in line with the number of female members. We hope that this motivates a move towards the equality objectives for 2030. A clear and fundamental societal change is needed, with fair and more consistent institutional policies and framework commitments in the areas of science, medicine, and global health. Gender equality and diversity taskforces are essential to achieve these goals. Patient summary: We analysed the male/female ratio for participants in annual meetings held by the European Association of Urology and the European Society for Paediatric Urology. From a low level in 2012, the ratio increased to over 30% in 2022, in line with the female membership of the societies. Focus on fair and consistent policies is needed to ensure that women are well represented in medicine.
RESUMO
INTRODUCTION: A TCS after primary closure of meningomyeloceles is a known complication of the spina bifida disease. Data on the outcome after SSCU surgery is heterogeneous and lacking standardization. Thus we aimed to find a reliable system for assessment of the bladder function before and after SSCU surgery and document postoperative outcome. METHODS: A retrospective study was performed on a cohort of patients with spina bifida diagnosis. In total, 130 patients underwent 182 SSCU surgeries, 56 of those met our inclusion criteria. A classification system, including two different methods, was used. The AC system used baseline pressure and detrusor over activity to define three levels of bladder dysfunction, the second method ranked the severity of bladder dysfunction by awarding points from 0 to 2 for bladder capacity, maximal detrusor pressure during autonomous contractions, leak point pressure and vesicoureteral reflux A high score is correlated with a severe bladder dysfunction. RESULTS: Gender distribution was equally (male: n = 29; 51.8%; female: n = 27; 48.2%). The median age at SSCU was 902 years (range 0.5-22.8 years). After SSCU, the stage improved in 11 patients (19.6%), worsened in 11 (19.6%) patients and remained the same in 34 patients (60.7%) after intervention (AC score). Non-worsening was observed in a total of 45 cases (80.4%) (p < 0.001). MHS score (n = 27, 48.2%) improved, remained unchanged (n = 12, 21.4%), 17 patients worsened (30.4%). Non-worsening in postoperative bladder functional outcome was demonstrated in 39 cases (69.6%) over all (p < 0.005). Regardless of whether bladder function is categorized by AC or MHS, postoperative outcome worsened significantly when SSCU was performed due to increasing deterioration in motor function alone (p < 0.05). Of the 24 cases with NOD as indication, 22 (91.7%) had an unchanged (n = 10; 41.7%) or improved (n = 12; 50.0%), meaning positive neuro-orthopedic outcome, only 2 (8.3%) deteriorated (p < 0.001). CONCLUSION: Our study presents reliable evaluation systems for bladder function in spina bifida patients. Since indications for SSCU surgery differ, it is important to know the possible effects on bladder function after this surgical procedure. Even a mild impairment of bladder function has a risk to deteriorate after SSCU surgery. Particularly interesting becomes this with regard to the fact that the prevalence of TCS might become more frequent with the rising numbers of prenatal closures of meningomyeloceles.

Introduction: Renal allograft compartment syndrome (RACS) is a complication that infrequently occurs after renal transplantation. Tight muscle closure may lead to RACS due to compression of renal parenchyma or kinking of the renal vessels. Many techniques have been proposed in an attempt to achieve tension-free closure, which can be specially challenging in child recipients. We present our experience with Tutoplast® Fascia Lata (RTI Surgical Tutogen Medical GmbH Industriestrasse 6, 91077 Neunkirchen am Brand, Germany) closure. Methods: All pediatric patients who underwent renal transplantation in our center between 2012 and 2021 were reviewed. Eight patients with Tutoplast® Fascia Lata placed at the time of initial transplantation were identified. Donor and recipient characteristics, Doppler ultrasound findings, and overall patient and graft survival rates were analyzed. Results: Doppler ultrasound was performed intra-operatively after abdominal wall closure. If any sign of vascular compromise was seen, the abdominal wall was opened and the graft was revised. The Tutoplast® Fascia Lata implant was used to perform tension-free fascia closure and, afterwards, a Doppler ultrasound was performed to confirm the optimal renal artery perfusion and venous patency. Three of the renal transplantations were from a cadaver donor, with two of them en bloc. Living donor transplantation was performed in four cases. Among which, there was a case of auto-transplantation due to bilateral renal artery stenosis. None of the patients presented any complications of either short or long term that was derived from the abdominal closure with Tutoplast® Fascia Lata. There was also no record of graft failure till datum. Conclusions: Restricted volume of the recipient pelvic cavity and the size discrepancy between the recipient pelvic cavity space and the donor adult kidney may lead to RACS. Other situations that occur more infrequently, i.e., as en bloc or auto-transplantation, are prone to suffer the same problem. Tutoplast® Fascia Lata is a safe option for these patients.
RESUMO
Introduction: Frameshift in medical management as well as in surgical thinking is putting the patient as a whole is the focus, rather than just the disease. To optimize the treatment of our pediatric transplant patients in our institution, we changed in 2013 the transplant program setting, treating, and operating all patients with pediatric transplant exclusively in a pediatric environment. The aim of this study was to analyze whether or not this change had an impact on patients safety, patient population, and patients and transplant outcome. Methods: In the retrospective analysis, we compared transplant outcome of two eras. Era1 (2008-2012) solely included patients treated in the adult facilities, era 2 (2013-2017) patients were exclusively treated in the pediatric environment. Results: There were 53 patients with renal transplant, with era 1 (28 patients) and era 2 (25 patients). Overall mortality was 5.6%. Median recipient age at transplantation was 13.2 years in era 1 and 8.59 years in era 2, median recipient weight at transplantation was 41.7 kg in era 1 vs. 26 kg in era 2, median size 149. 5 cm (era 1) vs. 123 cm in era2 (p = 0.05). The direct recipient/donor weight ratio remained stable in both eras, for recipients below 20 kg we saw a larger weight mismatch in era 1 (0.84 vs. 0.66). In the subgroup of patients with congenital anomalies of the kidney and urinary tract (CAKUT) those were significantly younger at onset of dialysis (p < 0.001) and at time of transplantation (p < 0.001), also they were less in body weight (p < 0.01), and body size (p < 0.001), this subgroup was larger in era 2. HLA mismatch data, serum creatinine, and GFR yield comparable results in both groups. Median time to detection of DSA was 46.2 month (3.8 years). Conclusion: Since children with ESRD at the time of transplant trend to be younger and smaller, it is crucial to ensure a medical environment that is able to address their particular challenges. Even in this recipient cohort, renal transplantation can be performed safely as outlined by our data.
