Neuroblastoma accounts for a significant portion of childhood tumors and can present in a variety of ways. Pelvic neuroblastoma has been reported but few cases exist of neuroblastoma invading or originating from the bladder or prostate. We present a 4-year-old patient with pelvic neuroblastoma arising from the prostate and describe the medical and surgical management of this challenging case. While pelvic neuroblastoma may have an improved prognosis, this case demonstrates the challenging surgical decisions that accompany these patients to maintain quality of life while balancing oncologic efficacy of treatment.

However, robotic surgery is associated with longer operative time which is major determinant of surgery cost. The Da Vinci Xi system is the successor to the Si system with better robotic arm ergonomics, a mobile boom, and a targeting system designed to streamline robot docking. We hypothesized that these enhancements would reduce overall operative time and associated costs with RALP. Our aim was to compare operative time and outcomes for pediatric RALP using Da Vinci Si and Xi systems at our institution. METHODS: We performed a retrospective cohort study of all patients undergoing RALP at our institution between 2019-2022. We compared the final 24 months of the Da Vinci Si system to the first 12 months of the Xi system. Bilateral or re-do pyeloplasty, and patients undergoing multiple procedures were excluded. Primary outcomes were operating room (OR) time, estimated blood loss (EBL), and length of inpatient stay, and change in hydronephrosis post-operatively. We controlled for surgeon experience, patient age, sex, laterality, reason for presentation, and imaging characteristics. RESULTS: 101 patients were included with a median age of 6 years (IQR 2-12) and median follow-up of 6 months (IQR 3-14). There were no differences in age at surgery, laterality, sex, reason for presentation, or imaging findings between both cohorts. 92% of patients showed improvement in hydronephrosis post-operatively. Mean OR time (207 min vs 182 min, p=0.02) and EBL (5ml vs 2ml, p=0.02) were reduced in the Xi cohort. Length of inpatient stay was similar in both cohorts (p=0.13). CONCLUSIONS: For pediatric robotic-assisted laparoscopic pyeloplasty, the Da Vinci Xi has a similar high success rate and is associated with shorter OR time compared to the Si system. This reduction in OR time may increase the cost-effectiveness of utilizing a robotic approach.

Skin-to-stone distance and prone positioning can preclude percutaneous nephrolithotripsy (PCNL) in these patients. One underutilized alternative to ureteroscopic and percutaneous stone treatments is robotic-assisted laparoscopic pyelolithotomy (RALPL). Our group sought to examine the safety and efficacy of this approach in treating renal stones in a particularly obese, underserved cohort in Appalachia and compare their outcomes to patients who had RALPL for an alternative reason (concurrent UPJO, ureteral stricture, pelvic kidney). METHODS: We compiled all RALPL performed at our tertiary care institution from 1/2017-10/2023, which serves a majority of West Virginia. We identified obese patients and non-obese in this cohort and compared gender, BMI, laterality, stone burden, skin-to-stone distance, length of hospital stay, residual stone, complications within one month, blood loss, operative time, and follow up time. Obesity was defined as a body mass index (BMI) of>30.0 kg/m2. Stone-free rate was defined as lack of observable stone fragments noted at completion of procedure and lack of stone fragments noted on postoperative imaging. Appropriate statistical tests (chi2 and students t-tests) were performed using SPSS. RESULTS: In total, 13 non-obese and 17 obese patients underwent RALPL. There were no statistically significant differences in gender, laterality, stone burden, skin-to-stone distance, length of stay, residual stone, complications within one-month, operative time, or follow up time (Table 1). Obviously, there were significant differences in BMI, but also blood loss, in the obese and non-obese groups, with the non-obese group demonstrating less blood loss (27.7 vs. 74.4 mL, p=0.04). CONCLUSIONS: Herein, we indicate that RALPL is a reasonable option for management of large volume renal calculi in obese patients in a particularly at-risk cohort in rural Appalachia. Outcomes between obese patients and non-obese patients who have RALPL are similar, aside from blood loss, in which the difference does not reach clinical significance. Thus, RALPL may be offered to patients who cannot tolerate endoscopic stone surgery due to positioning, skin-to-stone distance, or both.

BackgroundTelemedicine is now commonplace and an accepted modality for delivering health care due to the coronavirus pandemic. It has proven useful in increasing access to traditionally limited subspecialties and bridged the gap of local regional geographic restraints. We report a follow up of our experience building tele-consultation capacity for pediatric urology in a resource constrained area. Specifically, we hypothesize that hybrid tele-consultation is a safe modality for postoperative evaluation. A secondary goal of this study is to evaluate perceived barriers to implementing this practice from the perspective of advanced practice providers (APPs).MethodsAfter obtaining IRB approval (IRB# 1910741113), patients were prospectively recruited for tele-consultation encounters with a tertiary academic center between August 2018 and March 2020 (pre-dating the coronavirus pandemic). Advanced practice providers received additional training in physical diagnosis and examination prior to returning to satellite clinics in their local communities and facilitating tele-consultation with an academic pediatric urologist. Postoperative outcomes were analyzed out to eight weeks and any peri- and postoperative complications were assessed using the Clavien-Dindo classification system. Finally, anonymous surveys were administered to the APPs at the conclusion of the recruitment period to assess their satisfaction with telemedicine clinics and perceived barriers to implementation.Results92 telemedicine encounters took place between August 2018 and March 2020. The most common reasons for presentation were undescended testis (UDT) (n=15), urinary tract infection (n=13) and enuresis (n=13). The most common surgical case booked by the APPs in the satellite clinic was orchiopexy (n=10). Mean distance travel saved was 299.8 miles. In 23 patients who were schedule surgery, only two patients (8.7%) had an initial diagnosis that differed with their APP pre-operative diagnosis. Of the 22 patients who underwent surgery, all elected telemedicine visits for postoperative evaluation. No patient experienced complications. Initial consultations averaged 14 minutes (range 9 to 20 minutes), while mean duration of postoperative evaluations was 9 minutes (range 6 to 13 minutes). With regards to surveys, APPs reported an overall positive experience with tele-consultation (4.5/5, n=7) and all planned on incorporating it into their future practice (4.9/5, n =7).ConclusionA hybrid tele-consultation video conferencing clinic with heavy reliance on APPs is a safe, reliable and economical way to address pediatric subspecialty surgical needs in the rural setting. With proper training and exposure, APPs can safely perform preoperative assessments and correctly refer patients for surgical intervention, adding efficiency to the surgical subspecialty workflow.

METHODS: For female robotic ureteral reimplantation, we have a stepwise approach for ureter identification that starts with ureter identification and dissection distal to uterine vessels. In some cases, additional step for proximal ureteral dissection with broad ligament window is required to better identify and isolate the ureter. Better exposure of the ureter can be achieved by complete medial mobilization of the broad ligament with division of the round ligament and the uterine vessels. In male patients, ureter is identified and dissected proximal to the vas difference. Next, we create the detrusor tunnel in an inverted Y fashion. Detrusorrhaphy starts with an inverted V stitch proximally and an anchoring stitch distally. Then, the tunnel is closed in interrupted fashion with inclusion of the ureter adventitia in the stitches to prevent ureteral slippage out of the tunnel. RESULTS: We demonstrated our technique with tips and tricks for robotic ureteral reimplantation in male and female pediatric patients with vesicoureteral reflux CONCLUSIONS: Robotic approach for pediatric ureteral reimplantation is a feasible technique Source of Funding: None © 2021 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 206Issue Supplement 3September 2021Page: e223-e223 Advertisement Copyright & Permissions© 2021 by American Urological Association Education and Research, Inc.MetricsAuthor Information Amr A.

BACKGROUND:Prenatal testicular torsion (PTT) is exceedingly rare in intrauterine development, often diagnosed at the time of birth and very rarely diagnosed in utero during routine gestational ultrasound. As a result, incidence is unknown, and there exists no consensus regarding the pathophysiology of this phenomenon nor universally recognized algorithms and guidelines regarding its diagnosis and management. Case Presentation. We present the case of an antenatally diagnosed torsion and our subsequent management which included ipsilateral orchiectomy and prophylactic contralateral orchiopexy via a scrotal approach.CONCLUSION:While controversy regarding surgical intervention in patients with unilateral PTT exists due to poor salvage rates-estimated to be less than 1%-the risk of anorchia is higher in affected patients due to limitations in the accuracy of detecting bilateral testicular involvement. Risk of misdiagnosis of bilaterality may lead to lasting sequelae such as infertility and devastating psychological consequences for affected patients, supporting the need for surgical exploration, as was performed in our case.

Introduction: To better understand how the COVID-19 pandemic has forced rapid operational changes in the global healthcare industry, changes implemented on an individual, institutional basis must be considered. There currently is not adequate literature about the overall impact COVID-19 has had on pediatric urology services worldwide. We believe that they have dramatically decreased during the COVID-19 crisis, but have adapted to accommodate changes. We hypothesize that patient care was widely variant due to inadequate standardized recommendations or crisis planning. Materials and methods: A web-based survey was deployed to 377 pediatric urologists globally via email to analyze COVID-19's impact on various types of pediatric urology practices. Key categories included impacts on elective services, telemedicine use, finances, and recovery operations. A total of114 responses were collected between April 29th - May 22nd, 2020. Results: The widespread cancellation of elective surgical procedures caused significant disturbances in the field. There was a uniform, significant increase (75%) in telemedicine use across practices. The pandemic has created many changes in care provision for physicians, institutions, and patients themselves. Furthermore, the sudden economic burden on healthcare facilities could lead to cost-cutting measures, creating further strain within institutions. Though telemedicine has its limitations, it is a very viable option when traditional services are unavailable. Conclusions: Immediate steps should be taken to ensure that the recovery phases of pediatric urology practices are as efficient as possible. Institutions should develop task forces to develop critical workflow processes in the event of health crises, while still maintaining patient-centered care. This will be essential in maximizing appropriate care allocation.

INTRODUCTION:Pediatric urology is a much-needed subspecialty with a breadth of complex disorders that can often prove challenging to diagnose and manage. Exacerbating this need is the minimal exposure medical trainees receive to pediatric urology. Pediatric urology arrived in West Virginia in 1983 but the subspecialty has been inconsistently represented since then. Currently there are 2 fellowship-trained pediatric urologists in the state of West Virginia, which has an area of approximately 24,038 square miles. We review our experience with the use of telemedicine in providing outreach to the wider parts of our medically underserved state and ultimately evaluate its efficacy from a patient-centric cost analysis and diagnosis concordance perspective. We hypothesized that the use of telemedicine would be cost and time-effective for patients in our rural state. METHODS:We retrospectively reviewed our series of patients presenting from outside telemedicine "referral centers" in Martinsburg, Parkersburg and Wheeling for pediatric urological consultation. We evaluated reason for consultation, geographic driving distance, drive time and travel cost saved from telemedicine consultation. RESULTS:A total of 92 patients presented to outside designated telemedicine centers from August 2018 to April 2020. The mean driving time saved utilizing telemedicine consultation was 4 hours and 46 minutes, and mean driving distance saved was 299.8 miles. Travel costs saved in terms of fuel averaged $173.88 per patient. The most common reason for consultation was undescended testis, followed by recurrent urinary tract infection and nocturnal enuresis. Of the 23 patients who required surgery, only 2 (8.7%) had an initial diagnosis that was not concordant with their operating room examination. CONCLUSIONS:While modest, our data indicate a modern solution to a historical need in our state. Our high diagnosis concordance rate (91.3%) shows that a well-trained advanced practice provider can adequately perform an operative evaluation via telemedicine.

METHODS: A 7-year-old female patient who presented with an incidental finding of right adrenal mass measuring 2.5 cm on US imaging. she had no history of hypertension and examination revealed normal BP. Laboratory workup was done and revealed normal levels of serum aldosterone, metanephrines and plasma renin activity. The mass was stable in size after 10 months follow up, however patient's family opted for surgical resection. patient was placed in flank position. We used 4 8 mm robotic ports and a 5 mm assistant port. We started by reflection of the colon and dissection the undersurface of the liver from the IVC and upper surface of the adrenal mass. The posterior peritoneum was incised to expose the plane between the IVC and the adrenal mass. adrenal mass was carefully dissected from the kidney, posterior abdominal wall and the IVC. The right adrenal vein was identified, controlled and divided. The mass was excised with preservation of the normal part of the adrenal gland. RESULTS: Total operative time was 2 hours and 50 minutes. Estimated blood loss was less than 5 milliliters. The patient was discharged home in less than 24 hours. Pathological examination revealed ganglioneuroma. CONCLUSIONS: Robotic approach for adrenalectomy in pediatric patients is a safe and feasible technique.

We present an unusual case of a rare ossifying renal tumor of infancy. A 6-month-old male initially presented with gross hematuria and without any palpable abdominal mass. Renal ultrasound and MRI showed a right lower pole, calcified, endophytic renal mass. Laparoscopic radical nephrectomy was performed without complications. Pathology demonstrated an ossifying renal tumor of infancy. We report this case, in addition to a review of the literature for similar cases, to highlight a rare renal tumor in infancy that can be managed laparoscopically.
