Abstract
PURPOSE Robot-assisted laparoscopic extravesical ureteral reimplantation has previously been described as a viable minimally invasive option to open surgery. However, concerns for robotic surgery have been raised owing to assumed higher costs and heterogeneous clinical outcomes. We hypothesized that similar hospital charges and clinical outcomes occur when comparing open and robotic cases in matched cohorts. MATERIALS AND METHODS Open and robotic reimplantation cases from 2013 to 2015 for primary vesicoureteral reflux were matched by age using 1:1 nearest neighbor matching. The matched cohorts were analyzed and compared for their direct itemized hospital charges per surgical case, complications, and clinical outcomes. RESULTS There were 38 patients in each group after age-matching the 135 patients. Operating room charges were higher for the robotic group compared to the open group (p=0.002), whereas pharmacy and laboratory costs were lower for the robotic group. However, there were no significant differences in total overall charges between the open and robotic groups with cystoscopy or without cystoscopy (p=0.345, p=0.533), since the median hospital stay length was shorter for the robotic group (p<0.001). Clinical success rates were identical for the two groups (open 94.8% vs robotic 94.8%). There were also no significant differences in number of complications between the two cohorts. CONCLUSIONS This is the first age-matched study comparing hospital charges and clinical outcomes of pediatric open and robotic reimplantation. While operating room charges were higher for the robotic cohort, lower hospitalization charges led to comparable overall hospital charges, as well as equivalent clinical outcomes for both cohorts. LEVEL OF STUDY Level III (Retrospective comparative study) TYPE OF STUDY: Retrospective Study.

Abstract
BACKGROUND Patients with a prenatal diagnosis of lower urinary tract obstruction (LUTO) may undergo prenatal interventions, such as vesicoamniotic shunt (VAS) placement, as a temporary solution for relieving urinary tract obstruction. A recent FDA communication has raised awareness of the potential neurocognitive adverse effects of anesthesia in children. We hypothesized as to whether a prenatal LUTO staging system was predictive of the number of anesthesia events for prenatally diagnosed LUTO patients. METHODS We retrospectively reviewed the prenatal and postnatal clinical records for patients with prenatally diagnosed LUTO from 2012 to 2015. Patients were stratified by prenatal VAS status and by LUTO disease severity according to Ruano et al. (Ultrasound Obstet Gynecol. 2016). RESULTS 31 patients were identified with a prenatal LUTO diagnosis, and postnatal records were available for 21 patients (seven patients in each stage). When combining prenatal and postnatal anesthesia, there was a significant difference in the number of anesthesia encounters by stage (1.6, 3.7, and 6.7 for Stage I, II, and III respectively, p = .034). Upon univariate analysis, higher gestational age (GA) at birth was associated with a decreased number of anesthesia events in the first year (p = .031). CONCLUSIONS The majority of infants with prenatally diagnosed LUTO will undergo postnatal procedures with general anesthesia exposure in the first year of life. Patients with higher prenatal LUTO severity experienced a higher number of both prenatal and postnatal anesthesia encounters. In addition, higher GA at birth was associated with fewer anesthesia encounters in the first year. LEVEL OF EVIDENCE This is a prognostic study with Level IV evidence.

Abstract
BACKGROUND There is a need for pediatric medical devices that accommodate the unique physiology and anatomy of pediatric patients that is increasingly receiving more attention. However, there is limited literature on the programs within children's hospitals and academia that can support pediatric device development. We describe our experience with pediatric device design utilizing collaborations between a children's hospital and two engineering schools. METHODS Utilizing the academic year as a timeline, unmet pediatric device needs were identified by surgical faculty and matched with an engineering mentor and a team of students within the Capstone Engineering Design programs at two universities. The final prototypes were showcased at the end of the academic year and if appropriate, provisional patent applications were filed. RESULTS All twelve teams successfully developed device prototypes, and five teams obtained provisional patents. The prototypes that obtained provisional patents included a non-operative ureteral stent removal system, an evacuation device for small kidney stone fragments, a mechanical leech, an anchoring system of the chorio-amniotic membranes during fetal surgery, and a fetal oxygenation monitor during fetoscopic procedures. CONCLUSIONS Capstone Engineering Design programs in partnership with surgical faculty at children's hospitals can play an effective role in the prototype development of novel pediatric medical devices. LEVELS OF EVIDENCE N/A - No clinical subjects or human testing was performed.

Abstract
BACKGROUND Re-do pyeloplasty after failed open or laparoscopic ureteropelvic junction (UPJ) obstruction correction can be a challenging procedure because of scar formation at the previous anastomosis site and decreased vascularity of the ureter. This study compared the perioperative parameters for pediatric robot-assisted laparoscopic (RAL) primary and re-do pyeloplasties with an emphasis on the intra-operative parameters. MATERIALS AND METHODS We compared the perioperative parameters of pediatric RAL procedures performed by a single surgeon at a tertiary care children's hospital for both primary ureteropelvic junction obstruction (UPJO) and recurrent UPJO after a previous open or laparoscopic procedure over 2013-2015. The operative time was subdivided as total operative time, console time, port placement time, dissection time to UPJ, and anastomosis time. RESULTS A total of 65 pediatric RAL pyeloplasty procedures for UPJO were performed (55 primary and 10 re-do pyeloplasties) during the study period. The console times were 43.3% longer for re-do pyeloplasties than for primary pyeloplasties (133.0 ± 30.7 versus 92.8 ± 24.0 minutes, respectively, P < .01). The re-do cases had longer operative times, especially for UPJ exposure (52.2 ± 21.0 versus 28.0 ± 14.0 minutes, P < .01). There were no conversions to open surgery or significant perioperative complications. There was no difference in hospital pain medication usage and hospital length of stay between the 2 groups. The treatment success rates were 98.2% (54/55) and 100% (10/10), respectively. CONCLUSIONS RAL re-do pyeloplasty is associated with significantly longer operative times as compared with primary pyeloplasties, especially during the exposure of the UPJ, but it is overall a safe and effective surgical modality for persistent/recurrent UPJO in children. As surgeons are increasingly asked for more accurate predictions of operative time lengths when scheduling cases, this information can be helpful for surgeons when scheduling these cases and with counseling families.

Abstract
INTRODUCTION We present a robot-assisted approach to surgical treatment of UPJ obstruction associated with crossed renal ectopia in a male infant. METHODS A 31 year-old woman presented at 37 weeks gestation for prenatal hydronephrosis and delivered at 39 weeks. Renal ultrasound identified the bladder and right kidney in a crossed ectopic position in the left pelvis, and MRI showed the cystic lesion to be hydronephrosis associated with a ureteropelvic junction obstruction of the crossed ectopic right kidney. At three months of age, a robot-assisted laparoscopic dismembered pyeloplasty was performed. Post-operative renal ultrasounds at one, two, and 7 months showed persistent but decreasing hydronephrosis. He remains asymptomatic. DISCUSSION Crossed renal ectopia with associated ureteropelvic junction obstruction has been reported in the literature and managed using both open and minimally invasive approaches. To our knowledge, this is the first reported robot-assisted pyeloplasty performed for this condition in an infant. CONCLUSIONS With careful patient selection, the robot-assisted laparoscopic approach can be applied to infants that require pyeloplasty for kidneys with anomalous development that have evidence of ureteropelvic junction obstruction.

Abstract
PURPOSE To describe the age of independence in intermittent self-catheterization (ISC) in a diverse patient population and identify factors associated with ISC in individuals with spina bifida. METHODS Two hundred patients with myelomeningocele or lipomyelomeningocele, who were ⩾ 3 years of age and utilized catheterization for bladder management were included. Data regarding diagnosis, functional level of lesion, race, ethnicity, presence of shunt, method of catheterization, self-management skills, fine motor skills, and cognitive abilities were collected. RESULTS Fifty-five percent of individuals were able to perform ISC with a mean age of 9.45 years (SD = 2.97) and 22.7% used a surgically created channel. Higher level of lesion and female gender were associated with a lower rate of ISC. Intellectual disability was present in 15% of the individuals able to perform ISC and in 40% of those not able to perform ISC (p= 0.0005). Existent self-efficacy regarding activities of daily living (i.e. dressing, bathing, skin care) were associated with ISC (p< 0.0001). CONCLUSIONS The average age of ISC emerged as a target for culturally-appropriate educational interventions to stimulate greater early independence. Future research on factors that may foster an 'independent spirit' early in childhood leading to self-management are warranted.

Abstract
PURPOSE Prenatal repair of myelomeningocele (MMC) via hysterotomy has demonstrated neurosurgical and motor benefits, when compared to postnatal repairs. Urologic benefits, however, remain to be seen. The purpose of this study was to review early postnatal bladder function in patients undergoing a novel endoscopic approach for MMC repair using an exteriorized uterus. METHODS A prospective urologic assessment of patients undergoing fetoscopic MMC repair and receiving subsequent care at our facility, was performed. Patients were managed and urodynamic studies risk-stratified according to the Centers for Disease Control and Prevention Urologic and Renal Protocol for the Newborn and Young Child with Spina Bifida. RESULTS Fetoscopic MMC repair was performed in 14 patients. No patients had hydronephrosis or bladder thickening at birth. Detrusor overactivity was observed in nine (64.3%) patients. Impaired compliance was seen in eight (57.1%) patients. No patients had a detrusor leak point pressure of > 40 cm H2O or evidence of detrusor sphincter dyssynergia. Three (21.4%) patients had vesicoureteral reflux, seven (50.0%) had an open bladder neck, and none had trabeculated bladders. CONCLUSION In this early experience with fetoscopic MMC repair, postnatal bladder function does not appear to be any worse than that of previously reported prenatal or postnatal closures.

Abstract
BACKGROUND The murine penis model has enriched our understanding of anomalous penile development. The morphologic characterization of the murine penis using conventional serial sectioning methods is labor intensive and prone to errors. AIM To develop a novel application of micro-computerized tomography (micro-CT) with iodine staining for rapid, non-destructive morphologic study of murine penis structure. METHODS Penises were dissected from 10 adult wild-type mice and imaged using micro-CT with iodine staining. Images were acquired at 5-μm spatial resolution on a Bruker SkyScan 1272 micro-CT system. After images were acquired, the specimens were washed of any remaining iodine and embedded in paraffin for conventional histologic examination. Histologic and micro-CT measurements for all specimens were made by 2 independent observers. OUTCOMES Measurements of penile structures were made on virtual micro-CT sections and histologic slides. RESULTS The Lin concordance correlation coefficient demonstrated almost perfect strength of agreement for interobserver variability for histologic section (0.9995, 95% CI = 0.9990-0.9997) and micro-CT section (0.9982, 95% CI = 0.9963-0.9991) measurements. Bland-Altman analysis for agreement between the 2 modalities of measurement demonstrated mean differences of -0.029, 0.022, and -0.068 mm for male urogenital mating protuberance, baculum, and penile glans length, respectively. There did not appear to be a bias for overestimation or underestimation of measured lengths and limits of agreement were narrow. CLINICAL TRANSLATION The enhanced ability offered by micro-CT to phenotype the murine penis has the potential to improve translational studies examining the molecular pathways contributing to anomalous penile development. STRENGTHS AND LIMITATIONS The present study describes the first reported use of micro-CT with iodine staining for imaging the murine penis. Producing repeated histologic sections of identical orientation was limited by inherent imperfections in mounting and tissue sectioning, but this was compensated for by using micro-CT reconstructions to identify matching virtual sections. CONCLUSION This study demonstrates the successful use of micro-CT with iodine staining, which has the potential for submicron spatial resolution, as a non-destructive method of characterizing murine penile morphology.

Abstract
BACKGROUND Utilization of the robotic approach to pyeloplasty continues to grow in the field of pediatric urology. Adoption in the infant population has perhaps been the slowest because of the limited operative domain and relatively large instruments. METHOD In this video, we demonstrate key steps in performing an infant robotic pyeloplasty using the smallest instruments currently available for the da Vinci S and Si systems (Intuitive Surgical, Sunnyvale, California). RESULTS At our institution, 20 robot-assisted laparoscopic infant pyeloplasties have been performed using 5-mm instruments. There have been no conversions to an open approach. The patient age ranged from 2 to 9 months old. The average operative time was 2 h and 28 min. CONCLUSION The treatment success rate was 95% at an average of 8.3 months of follow-up.

Abstract
BACKGROUND Testicular torsion (TT) remains one of the most common urological emergencies. The length of time from onset of symptoms to detorsion and degree of spermatic cord twisting are usually the most important factors for testicular damage. Therefore early presentation, accurate diagnosis, and prompt treatment are important factors for optimizing the testicular salvage rate. While delay in seeking medical attention is a common cause of testicular loss in pediatric patients with testicular torsion, delays in diagnosis and treatment can be preventable causes of testicular loss. OBJECTIVE In this study, we aimed to develop a standardized process to improve the patient flow from the Emergency Room (ER) to Operating Room (OR) for TT patients in an academic children's hospital. STUDY DESIGN Thirty consecutive pediatric patients with acute testicular torsion between November 2013 and July 2014 served as the control group. A scrotal pain checklist was implemented in July 2014, and 30 consecutive patients from July 2014 until April 2015 served as the study group. Perioperative parameters including times, ultrasound (US) findings, and surgical results were reviewed. RESULTS The mean ages of the control group and the study group were similar (12.3 ± 4.9 years and 11.5 ± 5 years, respectively) (p = 0.575). ER arrival to OR time, triage completion to OR time, and scrotal US to OR time were significantly decreased in the study group (p < 0.001) (Table). Although triage time and ER arrival to scrotal US times were decreased in the study group, the differences were not significant (p = 0.071, p = 0.112, respectively). DISCUSSION Utilizing scoring tools during the triage of patients with scrotal pain can help identify high-risk patients earlier and prevent unnecessary use of resources in an ER serving a large pediatric population. Limitations of this pilot study include the limited number of patients and the potential for the Hawthorne effect (staff awareness of the study). Additionally, we did not examine scrotal pain checklist scores for other acute scrotal diseases. This study focused on a quality improvement process for TT patients, in order to reduce ER to OR times. CONCLUSION A standardized process with use of a scrotal pain checklist and prompt communication between the ER, Urology, and Radiology teams led to significantly reduced times from the ER to the OR. Standardized processes for pediatric patients with testicular torsion may help to improve testicular survival rates.

Abstract
45,X/46,XY gonadal dysgenesis is a disorder of sexual differentiation with a wide clinical presentation, ranging from Turner-like females to individuals with genital ambiguity to azoospermic but otherwise normal-appearing males. Hence, patients can be assigned female or male sex. Female patients are managed according to the Turner Syndrome Guidelines, whereas males are managed on a case-by-case basis. Male patients present with multiple medical challenges: undervirilization, hypogonadism, gonadoblastoma risk, and short stature. Many require surgeries and hormonal treatments that are time-sensitive and irreversible. Nonetheless, these therapeutic decisions are made without evidence-based guidelines. This review describes the medical concerns and possible interventions in male patients with 45,X/46,XY dysgenesis for each stage of development. Interventions should be addressed within a patient-centered framework by a multidisciplinary team and after thorough discussion with the family. We use the GRADE system to appraise the existing evidence and provide recommendations based on the available evidence.
