Novel use of contrast enhanced ultrasonography with urodynamics in children: A comparison study to fluoroscopy.

INTRODUCTION: Video urodynamics (UDS) has classically been performed using fluoroscopy (fluoro). Contrast enhanced voiding ultrasonography (ceVUS) has rarely been reported for use with UDS. This is the first study to compare the imaging characteristics of ceVUS versus fluoro UDS. METHODS: Children were enrolled for ceVUS UDS who previously underwent fluoro UDS. Demographics, imaging data for ceVUS and fluoro UDS, time between studies, and clinical data between studies were recorded. Changes in clinical status included implantation/cessation of catheterization or anticholinergic medications, leakage between, urinary tract infections, hydronephrosis and neurologic changes. Comparison testing was performed using McNemar's Chi-Squared and Wilcoxon matched-pairs signed rank test. RESULTS: Seventy-five children were recruited. Median time between studies was 1.3 years (IQR 0.9-2.9). There were no differences for bladder shape (p = 0.59), vesicoureteral reflux (p = 0.10), bladder neck (p = 0.59) or urethra (p = 1.0) between studies. In 5 cases, the bladder neck could not be visualized adequately due to layering of the microbubble contrast against urine. Benefits to ceVUS included ability to visualize the exact moment the bladder neck opened. Following exclusion of patients with clinical changes that might affect imaging findings, an analysis of 28 patients demonstrated no differences between the two studies. CONCLUSIONS: CeVUS can be used adequately in conjunction with UDS. Limitations to ceVUS include more granular imaging for bladder shape versus fluoro and inability to visualize bladder neck if residual urine is in the bladder, mitigated by bladder emptying. Benefits include ability to visualize the dynamic activity of the bladder neck due to constant imaging with ceVUS.

Viability of contrast-enhanced voiding urosonography as an alternative to fluoroscopy during video urodynamics.

Pediatric urodynamic studies are performed to evaluate bladder function, commonly in conjunction with a voiding cystourethrogram (VCUG). Contrast-enhanced voiding urosonography (CeVUS) has been approved in the evaluation of vesicoureteral reflux and has been shown to have equal or superior diagnostic value to VCUG. In this technical innovation, we have shown that ultrasound contrast agent microbubbles are compatible with the equipment used for urodynamic evaluation. We have also shown that it is feasible to use contrast ultrasound in pediatric urodynamic examinations. The purpose of our study was to assess the technical feasibility of CeVUS during urodynamics with an in vitro test followed by a vivo evaluation. This single-center prospective study enrolled 25 patients aged 0-18 years who underwent CeVUS instead of VCUG at their regularly scheduled appointment. During the in vitro saline experiment, the radiologic and urologic equipment were found to be compatible. Microbubbles were observed at flow rates of 10 and 20 ml/min.

Long-term Outcomes After Gender-Affirming Surgery: 40-Year Follow-up Study.

BACKGROUND: Gender dysphoria is a condition that often leads to significant patient morbidity and mortality. Although gender-affirming surgery (GAS) has been offered for more than half a century with clear significant short-term improvement in patient well-being, few studies have evaluated the long-term durability of these outcomes. METHODS: Chart review identified 97 patients who were seen for gender dysphoria at a tertiary care center from 1970 to 1990 with comprehensive preoperative evaluations. These evaluations were used to generate a matched follow-up survey regarding their GAS, appearance, and mental/social health for standardized outcome measures. Of 97 patients, 15 agreed to participate in the phone interview and survey. Preoperative and postoperative body congruency score, mental health status, surgical outcomes, and patient satisfaction were compared. RESULTS: Both transmasculine and transfeminine groups were more satisfied with their body postoperatively with significantly less dysphoria. Body congruency score for chest, body hair, and voice improved significantly in 40 years' postoperative settings, with average scores ranging from 84.2 to 96.2. Body congruency scores for genitals ranged from 67.5 to 79 with free flap phalloplasty showing highest scores. Long-term overall body congruency score was 89.6. Improved mental health outcomes persisted following surgery with significantly reduced suicidal ideation and reported resolution of any mental health comorbidity secondary to gender dysphoria. CONCLUSION: Gender-affirming surgery is a durable treatment that improves overall patient well-being. High patient satisfaction, improved dysphoria, and reduced mental health comorbidities persist decades after GAS without any reported patient regret.

Pyeloplasty with ureteral stent placement in children: Do prophylactic antibiotics serve a purpose?

OBJECTIVES: Ureteral stents are commonly used during pyeloplasty to ensure drainage and anastomotic healing. Antibiotic prophylaxis is often used due to concerns for urinary tract infection (UTI). Although many surgeons prescribe prophylactic antibiotics following pyeloplasty, practices vary widely due to lack of clear evidence-based guidelines. We hypothesize that the rate of stent UTI does not significantly vary between children who receive antibiotics and those who do not. METHODS: We reviewed the medical records of 741 patients undergoing pyeloplasty between January 2010 and July 2018 across seven institutions. Exclusion criteria were: age older than 22 years, no stent placed, externalized stents used, and incomplete records. Surgical approach, age, antibiotic use, stent duration, Foley duration, and urine culture results were recorded. Patients were categorized into two groups, those younger than four years of age and those four years and older as proxy for likely diaper use. Univariate logistic regression was conducted to identify variables associated with UTI. Multivariable backward stepwise logistic regression was used to identify the best model with Akaike information criterion as model selection criteria. The selected model was used to calculate odds ratios and 95% confidence intervals summarizing the association between prophylactic antibiotics and stent UTI while controlling for age, gender, and intra-operative urine cultures. RESULTS: 672 patients were included; 338 received antibiotic prophylaxis and 334 did not. These groups differed in mean age (3.91 vs. 6.91 years, P < .001), mean stent duration (38.5 vs. 35.32 days, P < .001), and surgical approach (53.25% vs. 32.04% open vs. laparoscopic, P < .001). The incidence of stent UTI was low overall (7.59%) and similar in both groups: 31/338 (9.17%) in the prophylaxis group and 20/334 (5.99%) in the non-prophylaxis group (P = .119). Although female gender, likely diaper use, and positive intra-operative urine culture were each associated with significantly higher odds of stent UTI, prophylactic antibiotic use was not associated with significant reduction in stent UTI in any of these groups. Surgical approach, stent duration, and Foley duration were not associated with stent UTI. CONCLUSION: Incidence of stent UTI is low overall following pyeloplasty. Prophylactic antibiotics are not associated with lower rates of stent UTI following pyeloplasty even after controlling for risk factors of female gender, likely diaper use, and positive intra-operative urine culture. Routine administration of prophylactic antibiotics after pyeloplasty does not appear to be beneficial, and may be best reserved for those with multiple risk factors for UTI.

Benefits and barriers to pediatric tele-urology during the COVID-19 pandemic.

INTRODUCTION: Telemedicine video visits are an under-utilized form of delivering health care. However due to the COVID-19 pandemic, practices are rapidly adapting telemedicine for patient care. We describe our experience in rapidly introducing video visits in a tertiary academic pediatric urology practice, serving primarily rural patients during the COVID-19 pandemic. OBJECTIVE: The primary aim of this study was to assess visit success rate and identify barriers to completing video visits. The secondary aim identified types of pathologies feasible for video visits and travel time saved. We hypothesize socioeconomic status is a predictor of a successful visit. MATERIALS AND METHODS: Data was prospectively collected and analyzed on video visits focusing on visit success, defined by satisfactory completion of the visit as assessed by the provider. Other variables collected included duration, video platform and technical problems. Retrospective data was collected via chart review and analyzed including demographics, insurance, and distance to care. Socioeconomic status was estimated using the Distressed Communities Index generated for patient zip code. RESULTS/DISCUSSION: Out of 116 attempted visits, 81% were successful. The top two reasons for failure were "no-show" (64%) and inability to connect (14%). Success versus failure of visit was similar for patient age (p = 0.23), sex (p = 0.42), type of visit (initial vs. established) (p = 0.51), and socioeconomic status (p = 0.39). After adjusting for race, socioeconomic status, and type of provider, having public insurance remained a significant predictor of failure (p = 0.017). Successful visits were conducted on multiple common pediatric urologic problems (excluding visits requiring palpation on exam), and video was sufficient for physical exams in most cases (Summary Table). A median of 2.25 h of travel time was saved. CONCLUSIONS: While socioeconomic status, estimated using the Distressed Communities Index, did not predict success of video visits, patients with public insurance were more likely to have a failed video visit. There is compelling evidence that effective video visits for certain pathologies can be rapidly achieved in a pediatric urology practice with minimal preparation time.

Parental perception of bladder spasms and hematuria after surgery for vesicoureteral reflux: A prospective multicenter study.

INTRODUCTION: Anti-reflux surgery success has been well-documented in the literature. Little data exists about the characterization of the child's symptoms regarding pain, bladder spasms, and hematuria following these procedures. These symptoms may affect the choice of surgery for families and providers. OBJECTIVE: To characterize parent's perception of recovery from surgery and preparedness for recovery from surgery. We hypothesized that parents of children undergoing open intravesical reimplantation (Open) would report a higher incidence of bladder spasms and hematuria compared to children undergoing robotic extravesical reimplantation (RALR) or endoscopic treatment (DxHA). STUDY DESIGN: A 20-question survey was developed to assess perception of recovery preparedness, pain, and symptoms. Parents completed the survey at a follow-up visit occurring 3-6 weeks post-discharge. Chi-square and t-test or their non-parametric equivalents were used for between-group comparisons. RESULTS: Participating were three institutions and eleven surgeons. Eighty-four parents completed the survey a median of 33 days (IQR 27-40) post-surgery. More parents reported bladder spasms and hematuria in the Open group vs RALR and DxHA. Although there was no difference in maximum bladder spasm pain, duration of pain medication for spasms was longer with Open vs RALR. Most parents (87%) reported they were prepared for their child's symptoms after surgery. Approximately one-quarter of parents whose child underwent Open (33%) or RALR (36%) reported the bladder spasms were more painful than expected, and almost half of parents whose child underwent Open (49%) reported hematuria was worse than expected. DISCUSSION: We found that Open had significantly worse parental reports of bladder spasms, pain medication usage, and severity of hematuria than RALR and DxHA. Although most parents said they were prepared for their child's recovery, many reported the symptoms were worse than expected. These contradictions may reflect a need for improved physician to parent communication when discussing anti-reflux surgery.

Tele-Urology During COVID-19: Rapid Implementation of Remote Video Visits.

INTRODUCTION: COVID-19 has brought unprecedented challenges to the delivery of urological care. Following rapid implementation of remote video visits at our tertiary academic medical center serving a large rural population we describe and assess our experience with planned video visits and ongoing scheduling efforts. METHODS: Patients scheduled for video visits between April 14 and April 27, 2020 were included. Prospective and retrospective data were collected on patient and clinical characteristics as well as telemedicine outcomes. Multivariable logistic regression was performed to evaluate factors influencing video visit success. Concurrently scheduling data were collected from a separate cohort regarding patient access to technology and willingness to participate in video visits. RESULTS: A total of 209 patients were included with an overall video visit success rate of 67%. Of video visits that failed (69) reasons included no-show (35%), inability to connect to the telemedicine platform (23%) and lack of Internet access (10%). Nearly half of failed video visits (46.4%) were completed as phone visits. After adjustment for patient demographics commercial insurance was significantly associated with video visit success. In assessment of scheduling outcomes 179 patients were contacted to offer video visits. Of these patients 6.7% reported not having Internet access. Of those with Internet access 87% agreed to proceed with a video visit in lieu of visiting in person. CONCLUSIONS: Our experience indicates that rapid implementation of video telemedicine is feasible and highly accepted by patients. Efforts focused on standardized pre-visit patient education may further optimize successful telemedicine visits.

Identifying and addressing training deficiencies in the examination of cryptorchidism-a quality improvement study.

BACKGROUND: Accurate and timely diagnosis of cryptorchidism by primary care providers (PCPs) is critical to oncologic and fertility outcomes. Physical exam is the mainstay of diagnosis, but little is known about PCPs' skills in examining cryptorchid patients. Patients referred to surgeons for cryptorchidism often have normal or retractile testes on exam, and delayed or missed diagnosis of cryptorchidism may contribute to advanced age at surgical intervention. Previous studies on cryptorchidism have not investigated the baseline training, confidence, and/or exam skills of providers. OBJECTIVE: The authors aimed to define baseline training and provider confidence in the exam of cryptorchid patients and to improve examiner confidence using bedside teaching with a pediatric urologist. Secondarily, baseline training and confidence were correlated to skill. STUDY DESIGN: Medical students, family medicine, pediatrics, and urology residents, and pediatric attendings completed surveys on baseline training and self-reported confidence in the examination of cryptorchid patients at an academic institution from 2017 to 2018. N.G.K. (pediatric urologist) proctored examinations of cryptorchid patients and provided standardized grades and individualized feedback. Surveys were readministered after 3 months. Non-parametric comparison tests were performed to determine intervention effect and compare subgroups. RESULTS: Ninety-two respondents participated. 62% reported little to no formal training on the scrotal exam, 50% were self-taught, and 20% defined undescended testis incorrectly. Confidence increased with level of training, comparing attendings to residents to students (P < 0.001). Those who learned from a mentor had higher baseline confidence than those who did not (P < 0.01). Baseline confidence and amount of formal training positively correlated with exam skill as graded during proctored sessions (n = 59, P < 0.01). Provider confidence was higher after proctored exams (Fig. 2, n = 32, P < 0.0001). DISCUSSION: Significant training deficiencies exist in the examination of cryptorchid patients. A single proctored exam with a pediatric urologist can improve provider confidence and may improve exam skills. A rotation with pediatric urology, including proctored exams of cryptorchid patients, has become standard practice for pediatric trainees at the authors institution as a result of this study. CONCLUSIONS: While further studies are required to assess the effectiveness of bedside teaching and its impact on accurate and timely diagnosis of cryptorchidism, implementation of the authors quality improvement recommendations at other teaching institutions would help address training deficiencies in the examination of cryptorchid patients.

Complementary and Integrative Management of Pediatric Lower Urinary Tract Dysfunction Implemented within an Interprofessional Clinic.

Lower urinary tract dysfunction in children is a common multifactorial functional problem that often correlates with bowel dysfunction and behavioral disorders. Ideal management combines integrative therapies that optimize bladder and bowel habits, address behavioral issues, foster mind-body connection, and improve pelvic floor muscle dysfunction. Movement therapies that teach diaphragmatic breathing and relaxation, mind-body awareness, and healthy pelvic floor muscle function are vital for long-term symptom improvement in children. This paper outlines recommendations for integrative management of these patients and discusses a recently developed interprofessional clinic that aims to better meet these patients' complex needs and to provide patients with an integrated holistic plan of care. Additional work is needed to scientifically assess these treatment models and educate providers across the various disciplines that evaluate and treat these patients.

A practice pattern assessment of members of the Society of Pediatric Urology for evaluation and treatment of urinary tract dilation.

INTRODUCTION: Over the last decade the literature, including a multidisciplinary consensus statement, has supported a paradigm shift in management of urinary tract dilation, yet the impact on practice patterns has not been well documented. OBJECTIVE: This study aims to elucidate specific practice patterns for treatment of prenatal unilateral urinary tract dilation and to assess surgical intervention patterns for ureteropelvic junction obstruction. STUDY DESIGN: An online survey was distributed to 234 pediatric urologists through the Society of Pediatric Urology. The survey was composed of five clinical case scenarios addressing evaluation and management of unilateral urinary tract dilation. RESULTS: The response rate was 71% (n = 168). Circumcision status, gender, and grade were significant factors in recommending prophylactic antibiotics for newborn urinary tract dilation. Prophylactic antibiotic use in the uncircumcised male and female was twice that of a circumcised male for grade 3 (Table). This difference was minimized for grade 4. Use of VCUG was high for circumcised males with grade 3 or 4 (Table). The choice of minimally invasive surgery for ureteropelvic junction repair increased with age from 19% for a 5-month-old, 49% for a 2-year-old, and 85% for a 10-year-old. Notably, 44% of respondents would observe a 10-year-old with intermittent obstruction. Retrograde pyelography was recommended in conjunction with repair in 65% of respondents. Antegrade stent placement was the most common choice (38-47%) for urinary diversion after pyeloplasty. Regarding postoperative imaging, only 5% opted for routine renal scan whereas most would perform renal ultrasound alone. DISCUSSION: Practice patterns seen for use of prophylactic antibiotics are in agreement with the literature, which promotes selective use in those at highest risk for urinary tract infections. Interestingly, use of aggressive screening was not concordant with this literature. Several studies have indicated an increased usage of robotic pyeloplasty; however, results indicate that minimally invasive surgery is not preferred in those younger than 6 months. Study limitations include use of clinical case scenarios as opposed to actual clinical practice. CONCLUSION: Practice patterns for prophylactic antibiotic use for neonatal urinary tract dilation are dependent on gender, circumcision status, and grade. The use of minimally invasive surgery for ureteropelvic junction repair increased with patient age, with 50% preferring this modality at 2 years.

Delayed Partial Nephrectomy for Hydronephrosis After Renal Trauma.

Delayed sequelae following conservative management of renal trauma in the pediatric population are uncommon. Reports of delayed operations to manage these sequelae are even less common. Here we present the case of a 16-year-old male patient who had delayed development of upper urinary tract obstruction with recurrent infections following high-grade renal trauma managed conservatively. Ultimately, he required a robotic-assisted partial nephrectomy 2 years after initial nonoperative management. This is unique as no prior studies to our knowledge have described delayed hydronephrosis and delayed partial nephrectomy over a year following renal trauma.

11 Years Later-Isolated Testicular Relapse of ALL After Stem Cell Transplantation Treated With Surgery Only: A Case Report and Review of the Literature.

Despite advances in therapy for childhood acute lymphoblastic leukemia (ALL), relapses continue to occur and are associated with significant morbidity and mortality. Individuals who relapse after stem cell transplantation (SCT) have an especially poor prognosis and typically require intensive systemic therapy to provide any chance of cure. The majority of relapses occur within 2 years following SCT; relapses later than 4 years post SCT are rare. Here we describe an isolated testicular relapse of ALL 11 years after SCT, treated with local control measures only, and review the literature for other cases of very late ALL relapse following SCT.

Current applications of in utero intervention for lower urinary tract obstruction.

PURPOSE: Since the early 1980s with the inception of fetal intervention for obstructive uropathy, there have been creative attempts to improve both perinatal and long-term outcomes. Despite advances in technology and an improved understanding of lower urinary tract obstruction (LUTO) in the fetus, the results for these therapeutic interventions remain guarded and the long-term renal morbidity among survivors remains problematic. RECENT FINDINGS: Fetal LUTO represents a range of disorders but the most common of these is posterior urethral valves (PUVs). Selection criteria for candidates of possible intervention have improved with our understanding of fetal renal physiology. Serial urinalysis has marginally improved our ability to predict those that may ultimately respond to treatment [1,2], but the potential in the development of biomarkers for renal development or maldevelopment holds greater promise [3]. Advancements in fetal surgery may result in less fetal and maternal morbidity, but limited long-term improvement in outcomes highlights the controversial nature of the various interventions [4-10]. We must counsel families that fetal surgery offers hope but we cannot allow them to hold unrealistic expectations for cure. SUMMARY: In appropriately selected fetuses, intervention may improve perinatal survival but not without risk to mother and fetus. Long-term renal outcomes remain problematic amongst survivors. In the case of PUV, postnatal primary valve ablation remains the cornerstone of treatment for nephron preservation; however, our ability to mimic these results in the prenatal population remains poor [11]. Disease severity has likely predetermined those that will survive through the perinatal period with or without intervention. Nonetheless, our drive to assess and manage fetal obstructive uropathy perseveres so that we may ultimately relieve obstruction and preserve renal and lung function. We must maintain optimism that continued advances will ultimately improve outcomes, but also be realistic with our current expectations. This paper reviews the status of current in utero interventions and outcomes.

Bi-Institutional Comparison of Robot-Assisted Laparoscopic Versus Open Ureteroureterostomy in the Pediatric Population.

PURPOSE: Ureteroureterostomy (UU) is a useful surgical option for the management of duplication anomalies as well as obstructed single system ureters for children. We aimed to evaluate the safety, efficacy, and outcomes of robot-assisted laparoscopic UU (RALUU) compared with open UU (OUU) in the pediatric population. PATIENTS AND METHODS: A retrospective review was performed at two institutions including six surgeons' experience with all cases of RALUU and OUU from January 2005 to June 2014. Indications for a surgical procedure included duplex systems with an upper pole ectopic ureter, obstructed ureterocele or lower pole vesicoureteral reflux, and obstruction in a single system. Transureteroureterostomy, laparoscopic UU, and major reconstruction cases where UU was the secondary procedure were excluded. RESULTS: There were 25 RALUU and 19 OUU cases included. All cases involved duplex systems except two proximal to distal anastomoses in single system obstructed kidneys. RALUUs were more likely to be performed proximally (P = 0.01) and with the use of cystoscopy and stent placement (P = <0.0001). Operative times and estimated blood loss were similar between the two groups. Postoperative complications included four febrile urinary tract infections in each group, one recurrence of nonfebrile urinary tract infection in the open group, and one postoperative obstruction at the ureterovesical junction because of attempted stent placement necessitating nephrostomy tube placement in the open group. This OUU patient was the only one to demonstrate more severe hydronephrosis after surgery on initial follow-up imaging that was again unrelated to the open UU procedure. RALUU had shorter hospital stays by 0.5 days (P = 0.04). CONCLUSION: Robot-assisted laparoscopic UU is a safe and effective alternative to open UU in children with duplication anomalies and single system obstructed ureters. Operative times and complication rates were comparable with slightly shorter length of hospitalization in robotic cases.

Robot-assisted laparoscopic pyeloplasty: Multi-institutional experience in infants.

INTRODUCTION: Robot-assisted laparoscopic pyeloplasty (RALP) has been gaining acceptance among pediatric urologists. Over 300 have been described in the literature, but few studies have evaluated the role of RALP in infants alone. OBJECTIVE: We sought to examine the operative experience and outcomes of RALP in a cohort of infants treated at multiple institutions across the United States. Our primary aim was to describe the safety and efficacy of RALP within this cohort. We recognize the challenges of performing minimally invasive surgery in small patients. In our paper, we address some technical considerations for the infant population. STUDY DESIGN: This multi-centered observational study collected data on subjects one year of age or less who underwent RALP between April 2006 and July 2012 at five institutions. The primary outcome was resolution of hydronephrosis, and secondary outcomes included surgical time and complications. RESULTS: A total of 60 patients (62 procedures) underwent RALP by six surgeons during the study period. All surgeons had > 5 years of experience beyond fellowship training. Mean surgical age was 7.3 months (SD ± 1.7 mo), 56 patients (95%) were diagnosed prenatally, and 59 patients (95%) had follow up imaging. Of these patients, 91% showed resolution or improvement of hydronephrosis. Two patients had recurrent obstruction and required additional surgery. Mean surgical time was 3 hours 52 minutes (SD ± 43 minutes). Seven (11%) patients reported intra-operative or immediate post-operative complications. DISCUSSION: This series found a 91% success rate for reduction or resolution of hydronephrosis, and an 11% complication rate. This is equivalent to modern series comparing open pyeloplasty to pure laparoscopic and robotic-assisted laparoscopic pyeloplasty, which report success rates ranging from 70-96%, and complication rates ranging from 0-24% for open pyeloplasty. We lacked a standardized technique amongst institutions. This was not surprising since there are not established technical benchmarks for this surgery. However, we specified multiple technical considerations for this unique patient population. CONCLUSION: The advantages of using robot-assistance to perform pyeloplasty in infants remain to be defined. This study cannot make that assessment due to small sample size. Nonetheless, this cohort is the largest robotic pyeloplasty series in infants to date. Seeing an excellent success rate and a low complication rate in this infant cohort is encouraging.

Laparoscopic percutaneous inguinal hernia repair in children: review of technique and comparison with open surgery.

INTRODUCTION: Minimally-invasive approaches for inguinal hernia repair have evolved from conventional laparoscopy requiring placement of three ports and intracorporeal suturing to simple, one and two port extraperitoneal closure techniques. We utilize a single port laparoscopic percutaneous repair (LPHR) technique for selected children requiring operative intervention for inguinal hernia. We suspect that compared to open surgery, LPHR offers shorter operative duration with comparable safety and efficacy. Our objectives are to (1) illustrate this technique and (2) compare operative times and surgical outcomes in patients undergoing LPHR versus traditional open repair. METHODS: We reviewed operative times, complications, and recurrence rates in 38 patients (49 hernias) who underwent LPHR at our institution between January 2010 and September 2013. These data were compared with an age-, gender-, weight-, and laterality-matched cohort undergoing open repair during the same 3 year period. All cases were performed by a pediatric urologist or pediatric surgeon. RESULTS: Thirty-eight patients with a median age of 21.5 months underwent LPHR, and 38 patients with a median age of 23 months underwent open repair. In both groups, 27/38 patients (71%) had unilateral repairs, and 11/38 patients (29%) had bilateral repairs. For unilateral procedures, average operative duration was 25 min for LPHR and 59 min for OHR (p < 0.001). For bilateral procedures, average operative duration was 31 min for LPHR and 79 min for OHR (p < 0.001). There were no intraabdominal injuries in either group. In the LPHR group, there were no vascular or cord structure injuries and no conversions to open technique. Median follow-up was 51 days for the LPHR group and 47 days for the OHR group (p = 0.346). No hernia recurrence was observed in either group. CONCLUSIONS: In select patients, LPHR is an efficient, safe, and effective minimally invasive alternative to OHR, with reduced operative times but without increased rates of complications or recurrences. The technique has a short learning curve and is a practical alternative to OHR for pediatric urologists who infrequently utilize pure laparoscopic technique.

Identification of adolescent and adult patients receiving pediatric urologic care and establishment of a dedicated transition clinic.

INTRODUCTION: Pediatric patients with chronic urologic conditions frequently require lifelong evaluation and treatment. Transition to adult urologic care is critically important as these patients mature and the goals of care shift to include sexual function, fertility, and reconstruction. OBJECTIVE: Our objectives are to (1) quantify and describe the population of young adult patients with congenital or childhood-acquired urologic problems who continue to be followed in pediatric urology clinic, to (2) discuss the numerous obstacles to successful care transition, and to (3) outline the design features of the dedicated transition clinic we established in response to the identification of a sizeable population in need. STUDY DESIGN: We (1) performed a retrospective review of our electronic health record to identify young adult patients 19-35 years of age seen in pediatric urology clinic over a five year period. Patients without a chronic urologic diagnosis were excluded. We identified each patient's primary diagnosis and status with respect to transition of care. We then (2) established a dedicated transition clinic to facilitate progression to adult care services at our institution. RESULTS: Among 480 young adult patients seen in the pediatric clinic during the five-year period, 99 patients with an average age of 22.4 years were identified as having a chronic congenital or childhood-acquired diagnoses requiring urologic care. At the end of the five-year period, 40 of 99 patients (40.4%) had successfully transitioned to adult care while 59 patients (59.6%) continued care with pediatric urology. Among patients yet to transition, spinal dysraphism (30%) was the most common primary diagnosis. In this same group, discussion regarding transfer to adult care was documented during at least one visit in only 8 of the 59 patients (13.6%). All patients in this cohort had healthcare needs that included sexual function, fertility, or reconstruction. DISCUSSION: The present data confirm the presence of sizeable population of young adult patients with chronic urologic problems and maturing care needs who 1) continue to receive exclusively pediatric care, and 2) are rarely engaged in preparatory discussions regarding care transition. Obstacles to successful transition of care are numerous and include limited staff training, lack of identified staff member responsible for transition, financial and psychosocial barriers, and discomfort on the part of physicians, patients and families. We describe the additional challenges that are unique to transition of care in urology. We share a blueprint of our recently-established transition with the hope of prompting additional discussion and facilitating transitional urologic care elsewhere. CONCLUSION: Many young adult patients with chronic urologic conditions continue to receive care from pediatric urologists well into adulthood. We hope that our clinic might serve as a model for augmentation of urologic transition services at other institutions. We anticipate a future report evaluating our clinic's impact on long-term follow up, clinical outcomes, and patient satisfaction.

Minimally invasive techniques for management of the ureterocele and ectopic ureter: upper tract versus lower tract approach.

The optimal management approach for children with ureterocele and complete pyeloureteral duplication, especially in the setting of high-grade ipsilateral vesicoureteral reflux, remains unclear. Trends in surgical management reflect a shift from single-stage open reconstruction toward conservative management and minimally invasive approaches. This article reviews lower tract approaches (endoscopic ureterocele incision and ipsilateral ureteroureterostomy), and upper tract approaches (ureterocele moiety heminephrectomy) in terms of selected operative techniques, patient selection, published outcomes, postoperative care, and follow-up. Current data support endoscopic puncture as a safe and effective treatment of symptomatic children with single-system intravesical ureteroceles.

Can we predict a national profile of non-attendance paediatric urology patients: a multi-institutional electronic health record study.

BACKGROUND: Non-attendance at paediatric urology outpatient appointments results in the patient's failure to receive medical care and wastes health care resources. OBJECTIVE: To determine the utility of using routinely collected electronic health record (EHR) data for multi-centre analysis of variables predictive of patient noshows (NS) to identify areas for future intervention. METHODS: Data were obtained from Children's Hospital Colorado, Rady Children's Hospital San Diego and University of Virginia Hospital paediatric urology practices, which use the Epic® EHR system. Data were extracted for all urology outpatient appointments scheduled from 1 October 2010 to 30 September 2011 using automated electronic data extraction techniques. Data included appointment type; date; provider type and days from scheduling to appointment. All data were de-identified prior to analysis. Predictor variables identified using χ(2) and analysis of variance were modelled using multivariate logistic regression. RESULTS: A total of 2994 NS patients were identified within a population of 28,715, with a mean NS rate of 10.4%. Multivariate logistic regression determined that an appointment with mid-level provider (odds ratio (OR) 1.70 95% CI (1.56, 1.85)) and an increased number of days between scheduling and appointment (15-28 days OR 1.24 (1.09, 1.41); 29+ days OR 1.70 (1.53, 1.89)) were significantly associated with NS appointments. CONCLUSION: We demonstrated sufficient interoperability among institutions to obtain data rapidly and efficiently for use in 1) interventions; 2) further study and 3) more complex analysis. Demographic and potentially modifiable clinic characteristics were associated with NS to the outpatient clinic. The analysis also demonstrated that available data are dependent on the clinical data collection systems and practices.
