Mobility and Sporting Activity After Renal Trauma: A Survey Regarding Best Clinical Practice During the Recovery Stage.

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.

A multi-institutional European comparative study of open versus robotic-assisted laparoscopic ureteral reimplantation in children with high grade (IV-V) vesicoureteral reflux.

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.

Undescended testis: A roundtable discussion based on clinical scenarios - Part 1.

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.

Primum Non Discernere: Glass Ceilings and Female Representation at the European Association of Urology and European Society for Paediatric Urology Annual Meetings, 2012-2022.

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.

Robotic approach with neoadjuvant chemotherapy in adult Wilms' tumor: A feasibility study report and a systematic review of the literature.

Objective: The incidence of Wilms' tumor (WT) among adult individuals accounts for less than 1% of kidney cancer cases, with a prognosis usually less favorable when compared to younger individuals and an overall survival rate of 70% for the adult patients versus 90% for the pediatric cases. The diagnosis and treatment of WT are complex in the preoperative setting; neoadjuvant chemotherapy (NAC) or robotic surgery has rarely been described. This study aimed to review the literature of robotic surgery in WT and report the first adult WT management using both NAC and robotic strategy. Methods: We reported a case of WT managed in a multidisciplinary setting. Furthermore, according to Preferred Reporting Items for Systematic reviews and Meta-Analyses recommendations, a systematic review of the literature until August 2020 of WT treated with a robotic approach was carried out. Results: A 33-year-old female had a diagnosis of WT. She was scheduled to NAC, and according to the clinical and radiological response to a robotic radical nephrectomy with aortic lymph nodes dissection, she was managed with no intraoperative rupture, a favorable surgical outcome, and a follow-up of 25 months, which did not show any recurrence. The systematic review identified a total number of 230 cases of minimally invasive surgery reported in the literature for WT. Of these, approximately 15 patients were carried out using robotic surgery in adolescents while none in adults. Moreover, NAC has not been administered before minimally invasive surgery in adults up until now. Conclusion: WT is a rare condition in adults with only a few cases treated with either NAC or minimally invasive approach so far. The advantage of NAC followed by the robotic approach could lead to favorable outcomes in this complex scenario. Notwithstanding, additional cases of adult WT need to be identified and investigated to improve the oncological outcome.

Robotic Partial Nephrectomy for Bilateral Renal Masses.

PURPOSE OF REVIEW: There are very few data on patients undergoing robot-assisted partial nephrectomy (RAPN) for bilateral renal masses. The aim of this review is to update the literature and discuss the controversial points on this topic. RECENT FINDINGS: Nine papers have been published regarding RAPN for bilateral renal masses. In particular, five papers were case reports while the remaining four reported patient series. Concerning the outcomes, all these papers highlighted the safety, feasibility, and efficacy of bilateral RAPN for bilateral renal masses. The literature confirmed RAPN as an optimal procedure for the treatment of bilateral renal masses. However, these outcomes mainly derived from selected group of patients who underwent complex surgical procedures by expert robotic surgeons at high volume centers and cannot be generalizable to all categories of patients or centers. The simultaneous bilateral approach resulted feasible showing some advantages and without higher complications than a staged procedure in particular when clampless or selective clamping techniques were performed.

Being born small for gestational age (SGA) might be associated with a higher reoperation rate in proximal hypospadias.

PURPOSE: Being born small for gestational age (SGA) is associated with a higher frequency and more severe forms of hypospadias as well as with potential developmental differences. This study aims to characterize operative outcomes in SGA boys compared to boys born with normal weight and length for gestational age (appropriate/large for gestational age, AGA/LGA). METHODS: Demographic data, hypospadias characteristics, associated pathologies and operative outcomes of boys who underwent hypospadias repair at a single center (10/2012-10/2019) were evaluated. Boys were categorized into SGA and non-SGA, which were then compared using unpaired t-tests and chi square tests. To examine the effect of SGA on reoperative risk, a logistic regression model was applied integrating surgical technique, meatal localization and complex hypospadias (narrow glans/plate, curvature, micropenis, bilateral cryptorchidism). RESULTS: SGA boys accounted for 13.7% (n = 80) of the total cohort (n = 584) and 33% of all proximal hypospadias (n = 99, SGA vs. non-SGA 41.3% vs. 13%, p < 0.001). After a mean follow-up of 18.6 months the reoperation rate for all hypospadias was 17.9% (n = 105). In distal hypospadias there was no difference in reoperation rate between SGA and AGA/LGA boys (p = 0.548, multivariate regression model). For each meatal localization in proximal hypospadias SGA was a significant, independent factor predicting higher reoperation rates (p = 0.019, OR 3.21) in a logistic regression model (Figure ROC). DISCUSSION: Hypospadias surgery carries a substantial risk for unplanned reinterventions. Apart from meatal localization, there are only a few factors (urethral plate quality, glandular diameter, curvature) reported in literature to be associated with reoperative risk. Intrauterine growth retardation associated with SGA might lead to not only a higher probability of proximal hypospadias but also contribute to a higher risk for complications mediated by developmental differences. Whether these findings could help to tailor surgical strategies or adjuvant measures, as for example the application of preoperative hormonal stimulation remains to be determined in future studies. This study is limited by being a single-center series with limited follow-up resulting in some complications probably not yet detected - however, in the same extent in both groups. CONCLUSION: Based on this study, 33% of all proximal hypospadias cases occur in boys born SGA. While the reoperation rate in boys with distal hypospadias was not influenced by SGA status, SGA proved to be an independent predictor of a higher risk of reoperation in those with proximal hypospadias. After validation of these findings in other centers, this could be integrated into counseling and risk-stratification.

Guideline Adherence of Paediatric Urolithiasis: An EAU Members' Survey and Expert Panel Roundtable Discussion.

Background: Paediatric nephrolithiasis has increased globally, requiring standardized recommendations. This study aims to assess the paediatric urolithiasis care between EAU members along with the statements of three experts in this field. Methods: The results of an electronic survey among EAU members comparing the guideline recommendations to their current practice managing paediatric nephrolithiasis in 74 centres are contrasted with insights from an expert-panel. The survey consisted of 20 questions in four main sections: demographics, instrument availability, surgical preferences and follow-up preferences. Experts were asked to give insights on the same topics. Results: A total of 74 responses were received. Computerised Tomography was predominantly used as the main imaging modality over ultrasound. Lack of gonadal protection during operations was identified as an issue. Adult instruments were used frequently instead of paediatric instruments. Stone and metabolic analysis were performed by 83% and 63% of the respondents respectively. Conclusions: Percutaneous Nephrolithotomy is the recommended standard treatment for stones > 20 mm, 12% of respondents were still performing shockwave lithotripsy despite PNL, mini and micro-PNL being available. Children have a high risk for recurrence yet stone and metabolic analysis was not performed in all patients. Expert recommendations may guide clinicians towards best practice.

Surgical Management of Synchronous, Bilateral Renal Masses: A 1-decade Referral Center Experience.

BACKGROUND: Management and decision-making in patients with bilateral renal masses are controversial. OBJECTIVE: To report our experience of surgical management in patients with bilateral renal masses undergoing surgery at a high-volume center. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively collected data from patients treated with partial nephrectomy (PN) or radical nephrectomy for bilateral renal masses at a single referral institution between June 2008 and June 2019. Patient- and tumor-related features, timing (one vs two stage), and surgical approach (open vs robotic) were analyzed. SURGICAL PROCEDURE: A one- versus two-stage strategy was adopted according to the opportunity to perform at least one PN using a clampless or selective-clamping approach, in order to avoid acute kidney injury. MEASUREMENTS: Operative time, warm ischemia time, and intra- and postoperative complications were recorded. Histopathological results and tumor histology were assessed. RESULTS AND LIMITATIONS: Overall, 41 patients were included. The median age was 67 yr and the median preoperative estimated glomerular filtration rate (eGFR) was 84 ml/min/1.73 m2. The median Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) score was 8 (interquartile range [IQR] 7-8) for both sides. In 17 (42%) patients, a simultaneous approach was chosen, with a pure robotic approach in 11/17 cases, while among the 24 (58.6%) patients treated with a two-stage strategy, 15 (62.5%) were treated with a robotic approach on both sides. Intraoperative complications and postoperative major (CDC ≥3) complications were recorded in 7.3% and 4.9% of cases, respectively. The overall positive surgical margins rate was 2.4%. At a median follow-up of 42 (IQR 18-59) mo, the median eGFR was 73 (IQR 64-80) ml/min/1.73 m2, while disease-free survival and cancer-specific mortality were 90.2% and 7.3%, respectively. CONCLUSIONS: Our experience underlines that both simultaneous and staged surgical treatment of patients with bilateral renal masses are feasible and safe if grounded on proper patient selection. PATIENT SUMMARY: Management of patients with bilateral renal masses is challenging, given the heterogeneity of clinical scenarios and the need to optimize the timing of treatment to achieve maximal functional preservation while ensuring oncological efficacy.

Simultaneous robotic partial nephrectomy for bilateral renal masses.

PURPOSE: There is currently no consensus regarding the optimal treatment strategy for patients presenting with synchronous bilateral renal masses. The decision to perform bilateral procedures on the same intervention or in staged procedures is debated. The aim of this manuscript is to analyse the outcomes of simultaneous robot-assisted partial nephrectomy (RAPN) in a series of patients with bilateral renal masses treated at five Italian robotic institutions. METHODS: Data from a prospectively maintained multi-institutional database on patients subjected to simultaneous RAPN between November 2011 and July 2019 were reviewed. RAPNs were performed with da Vinci Si or Xi surgical system by expert robotic surgeons. Baseline demographics and clinical features, peri- and post-operative data were collected. RESULTS: Overall, 27 patients underwent simultaneous bilateral RAPN, and 54 RAPNs were performed without need of conversion; median operative time was 250 minutes, median estimated blood loss was 200 mL. Renal artery clamping was needed for 27 (50%) RAPNs with a median warm ischemia time of 15 minutes and no case of acute kidney injury. Complications were reported in 7 (25.9%) patients, mainly represented by Clavien 2 events (6 blood transfusions). Positive surgical margins were assessed in 2 (3.7%) of the renal cell carcinoma. At the median follow-up of 30 months, recurrence-free survival was 100%. CONCLUSION: Our data showed that, in selected patients and expert hands, simultaneous bilateral RAPNs could be a safe and feasible procedure with promising results for the treatment of bilateral synchronous renal masses.

A comparative study of anticoagulant/antiplatelet therapy among men undergoing robot-assisted radical prostatectomy: a prospective single institution study.

The present study aimed to assess the safety and efficacy of robot-assisted radical prostatectomy (RARP) in patients with prostate cancer (PCa) under anticoagulant (AC) and/or antiplatelet (AP) therapy, as compared to a control group, and to establish possible differences in postoperative-related morbidity. Data of all consecutive patients submitted to elective RARP for PCa from June 2017 to May 2020 at our institution were prospectively collected. Patients were divided according to the use of AC/AP therapy at surgery. The primary endpoint was to determine differences in 90-day postoperative complication rate, while secondary endpoints included differences in transfusion rate, readmission rate and postoperative oncological outcomes between the two groups. Sub-groups analysis was separately performed for patients undergoing pelvic lymphadenectomy and nerve-sparing procedures. Overall, 822 patients were included in the study and divided in 704 control-group patients (group A) and 118 patients under AC/AP therapy at surgery (group B). Despite the higher estimated blood loss between AC/AP takers and the control group, we did not find a significant difference in terms of 90-day postoperative complication rate, transfusion rate, readmission rate and postoperative oncological outcomes (all p > 0.05). In the cohort of patients undergoing nerve-sparing prostatectomy, a higher rate of complications and transfusions were found. At multivariate analysis, ASA score and ongoing medications were independently associated with complication in this sub-group. RARP can be safely and effectively performed in patients with PCa and ongoing AC/AP agents. Attention has to be paid in candidates for nerve-sparing procedures.

Treatment of ureteropelvic junction obstruction and urolithiasis in children with minimally invasive surgery.

BACKGROUND: Ureteropelvic Junction Obstruction (UPJO) is the most common congenital ureteral anomaly. Nowadays, according to the increasing incidence of urolithiasis, 20% of children with UPJO presents urolithiasis. Open pyeloplasty was the standard treatment before the introduction of minimally invasive surgery (MIS). Nevertheless, only scattered experiences on MIS were previously described and universal agreement on the treatment of UPJO plus urolithiasis is still missing. OBJECTIVE: The study aim was to describe our experience with a series of pediatric patients affected by UPJO and urolithiasis treated with robot-assisted pyeloplasty (RAP) and endoscopic removal of stones using a flexible cystoscope and a stones basket in a singular tertiary referral center. MATERIAL AND METHODS: We retrospectively reviewed our data from pediatric patients affected by UPJO and urolithiasis undergoing RAP between April 2013 and December 2019. The analysis was conducted on seven patients. All procedures were performed by one expert robotic surgeon and one endoscopic surgeon skilled in the management of urolithiasis. RESULTS: The mean age was 7 years (IQR 4-16). The median stone area was 77.7 mm two (IQR 50.2-148.4). Most of them (71.4%) presented preoperative symptoms. The median operative time was 110 min (IQR 104-125) with a console time of 90 (IQR 90-105). The median length of stay was 5 days (IQR 4-5). Median follow-up was 16 months (IQR 10-25). CONCLUSION: RAP with concomitant flexible ureteroscope is a safe and effective option for the simultaneous management of UPJO with urolithiasis with excellent outcomes in children.

Ureteral Reimplantation for Primary Obstructive Megaureter in Pediatric Patients: Is It Time for Robot-Assisted Approach?

Objective: To compare open and robotic approach for treatment of Primary Obstructive Megaureter (POM) in a series of pediatric patients. Materials and Methods: Medical records of all patients who had undergone ureteral reimplantation for POM at our institution, between January 2016 and December 2019, were retrospectively collected and analyzed. Open (Group B) and robotic (Group A) approach were compared. Success was defined as reduction of anteroposterior diameter of pelvis and ureter on postoperative ultrasound scan. Surgical complications were reported according to the Clavien-Dindo Classification. Esthetic results were compared through the Vancouver Scar Scale. Results: Out of 23 patients, 11 belonged to Group A (5M and 6F) and 12 to Group B (9M and 3F). Median age at diagnosis was 38 months in Group A and 46 months in Group B (P = .69). Operative times were comparable (150' Group A and 140' Group B; P = .35), but the hospital stay was significantly shorter in the robotic group (P < .01). Success rate was comparable: 90.9% in Group A and 91.7% in Group B, respectively (P = .95). Incidence of early complications was 9.1% in Group A (grade IIIB) and 8.3% in Group B (grade II) (P = .95). Esthetic evaluation obtained a median score of 1 in Group A and 3 in Group B (P < .01). Conclusions: Our preliminary experience shows that robotic reimplantation can be a safe option in the treatment of POM in pediatric patients with clinical outcomes comparable to the open technique.

Robot-assisted partial nephrectomy with 3D preoperative surgical planning: video presentation of the florentine experience

ABSTRACT Purpose: Three-dimensional (3D) virtual models have recently gained consideration in the partial nephrectomy (PN) field as useful tools since they may potentially improve preoperative surgical planning and thus contributing to maximizing postoperative outcomes (1-5). The aim of the present study was to describe our first experience with 3D virtual models as preoperative guidance for robot-assisted PN. Materials and methods: Data of patients with renal mass amenable to robotic PN were prospectively collected at our Institution from January to April 2020. Using a dedicated web-based platform, abdominal CT-scan images were processed by M3DICS (Turin, Italy) and used to obtain 3D virtual models. 2D CT images and 3D models were separately assessed by two different highly experienced urologists to assess the PADUA score and risk category and to forecast the surgical strategy of the single cases, accordingly. Results: Overall, 30 patients were included in the study. Median tumor size was 4.3cm (range 1.3-11). Interestingly, 8 (26.4%) cases had their PADUA score downgraded when switching from 2D CT-scan to 3D virtual model assessment and 4 (13.4%) cases had also lowered their PADUA risk category. Moreover, preoperative off-clamp, selective clamping strategy and enucleation resection strategy increased from CT-scan to 3D evaluation. Conclusion: 3D virtual models are promising tools as they showed to offer a reliable assessment of surgical planning. However, the advantages offered by the 3D reconstruction appeared to be more evident as the complexity of the mass raises. These tools may ultimately increase tumor's selection for PN, particularly in highly complex renal masses.
