RESUMEN
INTRODUCTION: Neurogenic detrusor overactivity (NDO) results in involuntary detrusor contractions during bladder filling or storage risking transmission of pressure to the upper urinary tracts and/or significant incontinence. The goals of bladder management in children with NDO prioritize the preservation of renal function, prevention of UTIs, and optimizing quality of life. First-line measures include intermittent catheterization and anticholinergic medication. However, when conservative measures fail, surgical intervention may be indicated. Historically, the next step was major reconstructive surgery to create a low-pressure urinary reservoir. The introduction of intravesical botulinum neurotoxin A (BoNT/A) for use in children in 2002 offered a less invasive option for management. However, its exact role is still evolving. AREAS COVERED: This article summarizes the mechanism of action of BoNT/A for management of NDO and evaluates the current literature defining common practice and clinical efficacy in children with NDO. The findings of the recently completed phase III trial for intravesical onabotulinumtoxinA in children are discussed in detail. EXPERT OPINION: As the first BoNT/A approved for use in children with NDO, onabotulinumtoxinA appears to be a safe and less invasive alternative to major reconstructive surgery. However, data defining appropriate patient selection and its role as a long-term treatment option continue to develop.

PURPOSE: Surgical interventions in the urologic management of children with neurogenic bladder secondary to spina bifida aim to preserve upper tract function, prevent urinary tract infections, and optimize quality of life. However, since the introduction of intravesical onabotulinumtoxinA (Botox) in the management of these patients, the indications for choosing Botox over augmentation cystoplasty (AC) remain undefined. The objective of this study was to determine which factors lead patients to undergo Botox versus AC as a primary surgical treatment after failing medical management. METHODS: We retrospectively reviewed the records of pediatric patients with myelomeningocele undergoing either primary Botox or primary AC at our institution between 2013 and 2018. We recorded demographic and clinical information. We identified 10 important clinical decision-making factors: bladder trabeculation, vesicoureteral reflux, or hydronephrosis on imaging; end-filling pressure (EFP) ≥40 cm H2O, detrusor overactivity, detrusor-sphincter dyssynergia, or reduced capacity on urodynamic studies; physician-perceived bladder hostility; and patient/family desire for continence and independence. The presence of these factors was compared between patients undergoing either primary Botox or primary AC. RESULTS: We identified 14 and 50 myelomeningocele patients who underwent primary AC and primary Botox, respectively. We found no significant differences in age, sex, race, or history of reconstructive surgery (antegrade continence enema or catheterizable channel). For the 10 decision-making factors, desire for independence/continence (p = <0.001) and reduced capacity (p = 0.002) were significantly associated with AC, while trabeculation (p = 0.006), EFP ≥40 cm H2O (p = 0.029), rising slope (p = 0.019), and physician-perceived hostility (p = 0.012) were significantly more common with Botox. CONCLUSIONS: At our institution, quality of life measures prompted AC over objective urodynamic or imaging findings before attempting Botox. These findings support a shared decision-making approach when considering surgical intervention for neurogenic bladder secondary to myelomeningocele.

BACKGROUND: Disturbances in gonadal development lead to increased risk of gonadal malignancy in some but not all patients with differences in sex development (DSD). However, the natural history of these tumors is poorly described, and the literature remains sparse. OBJECTIVE: The objective of this study was to describe the incidence of germ cell neoplasia in situ (GCNIS) and germ cell tumor (GCT) in a contemporary cohort of patients with DSD undergoing surgery and to provide long-term oncologic outcomes for these patients. STUDY DESIGN: Patients with DSD who have undergone gonadectomy or gonadal biopsy were identified at four institutions. Clinical characteristics, pathology, and treatment details were obtained retrospectively. Patients were stratified into risk categories based on DSD diagnosis. Oncologic treatment and outcomes were recorded. Descriptive statistics are reported using parametric methods. RESULTS: 83 patients were identified. Distribution of diagnoses is summarized in the summary table. 14 (16.9%) patients underwent gonadal biopsy, and 71 (85.5%) patients underwent gonadectomy (50/71 gonadectomies were bilateral). 8/83 (9.6%) patients had GCNIS or GCT (7 GCNIS, 1 GCT). Median age at surgery was 2.95 years (y) (interquartile range [IQR] 0.6-12.2) and 14y (IQR 0.85-16.9) in patients without and with GCNIS/GCT, respectively. All 8 patients with GCNIS/GCT had high or intermediate risk DSD diagnoses (4 mixed gonadal dysgenesis, 3 Turner with Y, 1 partial gonadal dysgenesis). Of the patients with high-risk diagnoses, 8/54 (15%) had GCNIS/GCT. No patient received adjuvant therapy, no patient had a recurrence, and all patients were living with mean follow up 6.4y. DISCUSSION: The risk of gonadal malignancy is heterogeneous in the DSD population and can vary based on DSD diagnosis as well as maturation, testicularization, and location of the gonads. The most recent consensus recommendations on gonadal management emphasize risk stratification and consideration of gonadal surveillance based on gender of rearing, but supporting literature remains sparse. In this contemporary cohort of DSD patients who underwent gonadal surgery, most patients did not have evidence of adverse pathology, all patients with malignant or premalignant pathology had a high/intermediate risk DSD diagnosis, and all patients with GCNIS/GCT were treated with surgery alone without recurrence. CONCLUSIONS: The distribution of patients with premalignant and malignant gonadal pathology and DSD in this cohort aligns with prior literature, and oncologic outcomes were excellent. These data add valuable information to the current literature and highlight the necessity to develop appropriate screening regimens for retained gonads.

BACKGROUND: Patient satisfaction surveys are increasingly utilized to assess patients' perceptions of their health care. Recently, these scores have been linked to payment, potentially incentivizing practices to meet certain metrics. We hypothesize that increasing pressures to receive positive reviews have led physicians to alter the delivery of their care to accommodate patient expectations over standards of care. METHODS: An 11-question REDCap™ survey was developed and emailed anonymously to all sixty-two surgeons across all surgical subspecialties at our children's hospital. Multiple-choice and open-ended questions were included. A modified Delphi method was used to acquire general consensus. RESULTS: Survey response rate for analysis was 41/62 (66%). 23 (56%) stated that they have changed their clinical practice patterns due to concerns regarding patient dissatisfaction. Examples of such changes included: requesting imaging tests or laboratory studies, performing invasive procedures, referring for second opinions, and prescribing medications. Only 2% felt that these interventions led to any significant change in outcome of a patient's condition. Several respondents expressed concerns that factors outside their control (scheduling, parking, wait times) contributed to patient dissatisfaction and affected providers' ratings, while others expressed concerns about inherent biases driving survey participants. CONCLUSIONS: As a result of patient satisfaction surveys, a significant number of surgeons reported altering their clinical practice beyond standard care to meet patient expectations. Some of these modifications included performing unnecessary interventions. Reliance on these surveys may be at odds with reducing health care costs and avoiding physician burnout. These and other unintended consequences of patient satisfaction surveys warrant further study before they are widely accepted as appropriate quality metrics. LEVEL OF EVIDENCE: Level IV, questionnaire.

INTRODUCTION: Pelvic Floor Biofeedback Therapy (PFBT) can be an effective treatment for pediatric lower urinary tract symptoms (LUTS). Due to differing perceptions of efficacy and practice patterns, we sought to further evaluate PFBT in our practice. We hypothesized that PFBT results in quiescence of EMG activity during voiding and improves questionnaire scores in patients with LUTS. METHODS: We retrospectively reviewed all patients undergoing PFBT and refined the analysis to females ≥6 years old with ≥2 sessions with completed voiding questionnaires pre- and post-treatment, active EMG during voiding, with non-neurogenic urinary tract complaints refractory to standard urotherapy. Validated Bladder Bowel Dysfunction (BBD) questionnaires were collected at each visit. Quiescence of EMG activity and changes in BBD score were the primary outcomes. RESULTS: 229 patients underwent ≥1 PFBT session, of which 64 females ≥6 years of age with ≥2 PFBT sessions and completed pre and post PFBT voiding questionnaires were identified. In this group, mean age at PFBT start was 10.1 (6.2-17.0). Patients completed 3.1 sessions (2-6). No difference was seen in post-void residual (PVR) between first and last session (23.8 vs 22.6 mL, P = 0.55). Median questionnaire score decreased from 18 (4-42) before to 13 (2-28) following PFBT (P < 0.0001). Responders, characterized by silencing of the EMG after PFBT, occurred in 31% (20/64). Non-responders were younger (P = 0.007) with higher pre-PFBT questionnaire scores. CONCLUSION: The use of PFBT appears to result in a significant reduction in symptom scores, though quiescence of EMG was observed following therapy in less than 1/3 of patients.

PURPOSE: Urodynamic findings often guide treatment for neuropathic bladder and are reported as objective data points in multi-institutional trials. However, urodynamic interpretation can be variable. In a pilot study pediatric urologists interpreting videourodynamics exhibited only moderate agreement despite similar training and practice patterns. We hypothesized the pilot study variability would be replicated in a multi-institutional study. MATERIALS AND METHODS: We developed an anonymous electronic survey that contained 20 scenarios, each with a brief patient history, 1 urodynamic tracing and fluoroscopic imagery. All videourodynamics were completed during routine care of patients with neuropathic bladder at a single institution. Pediatric urologists from Centers for Disease Control and Prevention Urologic Protocol sites were invited to complete an interpretation instrument for each scenario. Fleiss kappa and 95% confidence limits were reported, with Fleiss kappa 1.00 corresponding to perfect agreement. RESULTS: The survey was completed by 14 pediatric urologists at 7 institutions. Substantial agreement was seen for assessment of fluoroscopic bladder shape (Fleiss kappa 0.73), while moderate agreement was observed for assessment of bladder safety, end filling detrusor pressure and bladder capacity (Fleiss kappa 0.50, 0.56 and 0.54, respectively). Fair agreement was seen for electromyographic synergy and presence of detrusor overactivity (Fleiss kappa 0.21 and 0.35, respectively). CONCLUSIONS: Experienced pediatric urologists demonstrate variability during interpretation of videourodynamic tracings. Subjectivity of assessment of electromyographic activity and detrusor overactivity was confirmed in this expanded study. Future work to improve the reliability of videourodynamic interpretation would improve the quality of clinical care and the quality of multi-institutional studies that use urodynamic data points as outcomes.

INTRODUCTION: Low intensity focused ultrasound has recently been identified as a novel method of stimulating targeted neurons. We hypothesized that ultrasound stimulation of the posterior tibial nerve would inhibit bladder contractions in an established rat model of rhythmic bladder contractions. METHODS: Cyclical detrusor contractions were initiated by placing a transurethral catheter in female rats and infusing saline into the bladder. Transcutaneous ultrasound pulses were then delivered to the lower extremity of a rat (overlying the posterior tibial nerve) using a single element spherically focused 250 kHz transducer. Sixty-three cycles were repeated at 2 kHz for 300 ms at peak negative pressure of 900 kPa pulsed at 0.5 Hz. RESULTS: We report successful suppression of bladder contractions using ultrasound stimulation in 10 animals. The average latency between the initiation of ultrasound and suppression of bladder contractions was 3 min 23 s (±51 s), the average time of contraction suppression was 13 min and 50 s (±2 min 25 s) and the average time from the end of ultrasound to return of contractions was 9 min 37 s (±2 min and 30 s). CONCLUSION: In this work, we demonstrate the ability of targeted transcutaneous ultrasound to inhibit rhythmic bladder contractions in anesthetized rats. Due to its non-invasive nature and ease of application, we believe ultrasound mediated suppression of the micturition reflex is potentially an ideal outpatient treatment of overactive bladder and dysfunctional elimination.

PURPOSE: Urodynamic studies are crucial to neuropathic bladder management and they often determine surgical intervention. However, current evidence indicates that interpretations show poor agreement across physicians. We sought to determine the interrater reliability of urodynamic interpretation in our practice. We hypothesized that there would be strong correlation among pediatric urologists of similar training in a single academic practice. MATERIALS AND METHODS: We retrospectively identified patients with neuropathic bladder who underwent urodynamics at our institution between 2014 and 2015. An anonymous electronic survey (phase I) was developed with 20 clinical scenarios, each containing a brief history, a single urodynamic tracing and an accompanying fluoroscopic image. Faculty members assessed each tracing by an online instrument developed using urodynamic reports and published literature. The primary outcome was statistical correlation across raters as measured by the Spearman correlation coefficient. In a followup study (phase II) we investigated the sources of variability in urodynamic interpretations. RESULTS: Six faculty members completed the study with a response rate of 100%. In comparing urodynamic interpretation across raters, the faculty demonstrated a weak to strong correlation (rs 0.39-0.61, p <0.001). A strong correlation was found for fluoroscopic and clinical decision making variables, while electromyography synergy and detrusor overactivity demonstrated weaker correlation across physicians. CONCLUSIONS: Faculty interpretations of urodynamic tracings showed only moderate agreement despite a close working relationship and similar training at a single institution. Variability in interpretation can strongly impact patient treatment. Therefore, further work is needed to standardize the reporting and interpretation of urodynamic studies to optimize patient care.

PURPOSE: Sacral neuromodulation has been demonstrated to improve refractory bowel bladder dysfunction in children. The purpose of the current study was to determine whether results are durable in children after longer followup, whether children with a lower body mass index are at risk for device failure and whether pretreatment urodynamic evaluation can predict posttreatment outcome. MATERIALS AND METHODS: Pediatric patients with refractory bowel bladder dysfunction were enrolled following informed consent and followed prospectively. All patients underwent preoperative videourodynamic evaluation and a 2-stage implantation procedure. Validated questionnaires were used to assess symptom severity and quality of life. Complications were analyzed with regard to treatment required and patient body mass index. RESULTS: During 45 months 30 patients were enrolled. Median age was 8.3 years at enrollment. Median followup was 14.8 months. Patients had significant improvement in quality of life and symptom scores, which persisted at the most recent followup. Patients who had uninhibited detrusor contractions on preoperative urodynamic assessment had significantly greater improvement in symptoms. Of the patients 23% had a complication requiring reoperation, most commonly neurostimulator lead breakage in those with a significantly lower body mass index. CONCLUSIONS: Sacral neuromodulation significantly improves quality of life and symptom severity in children with refractory bowel bladder dysfunction. Children gain greater benefit if they show uninhibited bladder contractions on preoperative urodynamic evaluation. Children have a high rate of lead breakage requiring operative revision, which was seen after minor trauma in those with a lower body mass index.

PURPOSE: Literature pertaining to surgical disclosure to the pediatric patient is lacking. We hypothesized parents would find it difficult to disclose urologic surgery to a child. MATERIALS AND METHODS: Parents of patients <5 years old undergoing urologic surgery were contacted for telephone survey. Parents were asked about future plans of surgical disclosure, comfort with disclosure, and any support received. RESULTS: 98 parents consented to study participation. 87% of surgeries were on the genitalia with 62% being minor genitalia surgery (i.e. circumcision). 70% of parents would tell their child about minor genital surgery while 84% would tell about major genital surgery (p=0.07). 4 of 20 parents of children undergoing hypospadias repair (major genital surgery) did not plan to tell their child about surgery. All parents of children undergoing non-genital surgery would tell. Of all parents planning to tell their children about surgery, only 14% were nervous. 34% of parents would find guidance in talking to their child helpful despite the majority (90%) stating no guidance had ever been provided. CONCLUSIONS: Parents seem comfortable discussing urologic surgeries with a child but about 1/3 would appreciate further counseling. 20% of parents of children undergoing hypospadias repair hope to avoid telling their child.

INTRODUCTION: Constipation has been shown to have a significant impact on lower urinary tract symptoms (LUTS) in children, and treatment of constipation in children with bowel bladder dysfunction (BBD) has been shown to improve or completely resolve LUTS in many cases. Recent studies utilizing trans-abdominal ultrasound (US) to assess stool burden have correlated diagnosis of constipation with US appearance of rectal stool. An US scoring tool was published in 2008 to assess stool burden, showing linear correlation with constipation severity by symptom questionnaire in an outpatient pediatric constipation clinic population. We hypothesized that this US scoring tool would correlate with constipation symptoms in our outpatient pediatric urology population. METHODS: In 2010, our pediatric urology outpatient clinic began administering a previously published validated BBD questionnaire to new toilet-trained patients, containing three questions addressing bowel function. Patients in our clinic undergoing trans-abdominal US of the bladder also have assessment of their stool burden by the previously published US scoring tool. We retrospectively reviewed patient charts beginning in June 2013 who had undergone trans-abdominal US of the bladder, gathering data on the first 100 patients with a complete BBD questionnaire and a completed stool burden US scoring tool. RESULTS: Chart review of 272 consecutive patients was required to enroll 100 patients with a completed US scoring of stool burden and a completed BBD questionnaire. Of these 272 patients, 225 (82%) had a complete scoring of stool burden during their US examination. BBD questionnaires were complete in 107 of 272 patients (39%). Median patient age was 8.2 years, with 69% of patients being female. The most common diagnosis was incontinence or bladder dysfunction (41%). Only one patient (1%) had constipation as the primary diagnosis for their visit. Linear regression analysis showed no correlation of US score to patient reported frequency of bowel movement, frequency of hard stool, frequency of fecal incontinence, or all three symptoms combined. When investigating the subgroup of patients who had diagnoses of BBD/incontinence, this group was seen to have higher mean symptom scores than the entire cohort as a whole, but US scores were still widely variable and again did not correlate with symptom scores. CONCLUSION: US examination has previously been shown to correlate with symptom severity for children with chronic constipation in a pediatric constipation clinic setting. However, in a pediatric urology outpatient clinic setting at our institution, US examination did not correlate with patient reported symptoms.

OBJECTIVE: To assess the awareness and readiness of both spina bifida patients and parents regarding the transition process before transitioning, with a secondary aim that included identifying potential factors associated with successful transition. METHODS: All children aged ≥14 years requiring long-term care were prospectively enrolled. Questions designed by pediatric and adult urologists and an adolescent health specialist addressing the awareness of long-term follow-up and the desire to learn more about transitioning were administered by nursing staff at regularly scheduled clinic appointments. All spina bifida patients evaluated in the past 5 years were identified, and clinical factors associated with transitioning were compared. Statistical analysis using the Fisher exact test and the chi-square test were used to compare patients' and parents' responses and categorical variables between patients transitioned and those eligible. P <.05 was considered significant. RESULTS: A total of 33 surveys were prospectively collected. Twenty-two percent of parents and 40% of patients said they never wanted to transition (P = .28). Parents had thought about transitioning more than the patients (88.9% and 40%, respectively; P = .002). Of the 97 patients eligible for transition, 34% had a transition plan. The only significant predictor of transitioning to adult care was a previous history of stones (P = .03). CONCLUSION: Transitioning to adult urologic care is a necessity for many, and parents are significantly more aware of transitioning than the patient. Acknowledging and understanding the concerns of patients and families will help optimize the transition to adult urologic care.

PURPOSE: Bullying has become a social plague associated with various deleterious outcomes. We hypothesized that pediatric lower urinary tract symptoms could be associated with exposure to bullying. MATERIALS AND METHODS: We assessed exposure to school bullying via the Setting the Record Straight bullying questionnaire in children 8 to 11 years old being evaluated for lower urinary tract symptoms at our pediatric urology clinic. Lower urinary tract symptoms were quantified with the Vancouver Symptom Score. Children 8 to 11 years old presenting for pediatric well visits also completed the questionnaires. Linear regression assessed the relationship between Vancouver Symptom Score and bullying score. Categorical variables were compared by chi-square test, while continuous variables were compared using the Student t-test. RESULTS: A total of 113 children at the urology clinic and 63 children in the primary care setting consented to participate. There were significant differences between the 2 populations, including gender and race, with significantly more perpetrators of bullying in the primary care group (7.9% vs 0.9%, p = 0.02). When looking specifically at the urology group, there was a significant association between Vancouver Symptom Score and self-perceived (p <0.001) and peer perceived (p <0.001) victimization scores. In the primary care group there was also a significant association between Vancouver Symptom Score and self-perceived (p = 0.01) and peer perceived (p = 0.001) bullying perpetrator scores. Of children seen at the primary care office 33% had a significant Vancouver Symptom Score. CONCLUSIONS: Although bullying exposure is multifactorial, we found that Vancouver Symptom Score can be associated with bullying victimization and perpetrator scores.

OBJECTIVE: A major hurdle in management of any chronic pain syndrome is understanding the population in which it occurs. We describe our pediatric population of patients with peripubertal and postpubertal chronic orchialgia. PATIENTS AND METHODS: Pediatric patients ≥ 10 years of age seen between 2002 and 2012 were identified by ICD code 608.9, Male Genital Disorder NOS. Patients were included if they had orchialgia without identifiable cause lasting >3 months. Patient history, diagnostic evaluations, treatments, and outcomes were assessed. RESULTS: Seventy-nine pediatric patients were identified. The mean age was 13.3 years (range 10-18); mean duration of orchialgia was 16.3 months (range 3-85). Thirty-three of 79 (42%) had concomitant medical conditions and/or psychiatric-behavioral issues. The mean follow-up was 7.1 months (range 0-70.4) with 41/79 (52%) having more than one office visit follow-up. Eleven patients were referred to a pediatric pain clinic; 10 out of 11 (91%) were evaluated there. Overall, 16 out of 41 (39%) had resolution of pain: nine out of 41 (22%) responding to conservative management vs seven of 10 (70%) responding to pain clinic management (3 to anti-neuropathic medications, 4 to nerve block). CONCLUSION: Many pediatric patients with chronic orchialgia have co-morbidities amenable to multidisciplinary collaborative coordination of care. Referral to pediatric pain clinic can be of significant benefit.

PURPOSE: We theorized that progressive bladder dysfunction due to clinical diagnoses such as outlet obstruction occurs as a result of cyclical oxidative stress events. We hypothesized that measurement of F2-isoprostane, a marker of lipid peroxidation, could serve as a biomarker of oxidative stress in the murine bladder. MATERIALS AND METHODS: At age 5 to 6 weeks oophorectomized female mice were subjected to 1 of 2 bladder injury models, that is partial bladder outlet obstruction or acute bladder distension. The time points studied after injury included 4, 8 and 16 weeks after obstruction, and 0 to 48 hours after acute bladder distension. In a separate group short-term repetitive acute bladder distension was performed every other day for 14 days. Bladder samples were analyzed for F2-isoprostane using gas chromatography and mass spectroscopy. Mean tissue F2-isoprostane levels were compared. RESULTS: F2-isoprostane increased significantly after 4 weeks of partial bladder outlet obstruction from 1.46 ng/gm in controls to 2.31 ng/gm at 4 weeks (p = 0.01). Eight and 16 weeks after partial bladder outlet obstruction F2-isoprostane remained significantly elevated (2.39 and 2.48 ng/gm, respectively). Acute bladder distension resulted in a significant increase in F2-isoprostane immediately after distension compared to controls (1.6 vs 0.75 ng/gm, p = 0.04). In mice that underwent repetitive acute bladder distension F2-isoprostane did not change. CONCLUSIONS: Measurement of tissue F2-isoprostane in the bladder reflects the progression of oxidative stress, primarily in chronic injury models such as partial bladder outlet obstruction. The usefulness of F2-isoprostane measurements in shorter term injury models requires further study.

OBJECTIVE: Few studies of hypospadias repair in childhood have used validated questionnaires to investigate outcomes of cosmesis, urinary function, and sexual function in adulthood. We sought to investigate long-term outcomes in adult patients who had undergone severe hypospadias repair as children using an existing web-based application available to multiple institutions in order to develop an online patient survey of previously validated questionnaires. MATERIALS AND METHODS: Patients aged 18 years or older who underwent severe hypospadias repair between 1992 and 1997 at our institution were contacted to complete an online survey. Through medical chart reviews, we analyzed the location of meatus, type of repair, and complications. The online survey included questions about penile appearance, and validated questionnaires to assess urinary and sexual function. RESULTS: Of 58 patients who met the inclusion criteria, we contacted 19, and 13 completed the survey. Fifty-nine percent had complications, with an average of 2.2 procedures per patient. Most (85.0%) were satisfied with penile appearance, although 38.0% had residual penile curvature. Hypospadias patients had mean lower orgasmic function than normal controls. Mean scores for urinary function and other domains of sexual function were similar to normal controls. CONCLUSIONS: Although the majority of adult patients were satisfied with the outcomes of penile appearance, urinary function, and sexual function, our online survey suggests decreased lower orgasmic function as measured by validated questionnaire. An online survey accessible to multiple institutions with validated questionnaires may facilitate assessment of long-term hypospadias results.

OBJECTIVE: Patients with neurogenic bladder are at increased risk of developing upper tract stones. We hypothesized that patients with lower urinary tract stone disease are at greater risk of developing upper tract stones. METHODS: We performed a 10-year retrospective case-control study of patients with neurogenic bladder to determine the association between bladder and upper tract stones. Independent risk factors for upper tract stones were assessed. Cases and controls were matched 1:1. Univariable analysis was performed by Fisher's exact test and the Mann-Whitney U test. Multivariable logistic regression was performed. RESULTS: 52 cases and controls were identified. Cases were significantly more likely to be non-ambulatory, have bowel-urinary tract interposition, thoracic level dysraphism, and history of bladder stones. On multivariable analysis, independent predictors of stone formation were male sex (OR 2.82; p = 0.02), dysraphism involving the thoracic spine (OR 3.37; p = 0.014) bowel-urinary tract interposition (OR 2.611; p = 0.038), and a history of bladder stones (OR 3.57; p = 0.015). CONCLUSION: Patients with neurogenic bladder are at increased risk for upper tract stones. The presence of bladder stones may herald the development of upper tract stones. The predictors of stone disease identified should guide prospective studies to better understand the natural history of upper tract stone development in this population.

PURPOSE: Ileovesicostomy is a reconstructive option in complex urological cases but pediatric specific outcomes are lacking. We report our results with pediatric ileovesicostomy. MATERIALS AND METHODS: We retrospectively evaluated patients younger than 18 years undergoing incontinent ileovesicostomy at Vanderbilt University. History, urinary tract management and operative course were reviewed in the electronic medical record. Particular attention was given to immediate and long-term postoperative complications. RESULTS: Nine patients underwent incontinent ileovesicostomy between 2000 and 2013 at a mean age of 10.3 years (range 1.4 to 15.5). Surgical indication was sequelae of neurogenic or nonneurogenic neurogenic bladder (such as infection or worsening hydronephrosis) in 5 patients, reversal of vesicostomy in 3 and closure of cloacal exstrophy in 1. All 9 patients were thought incapable of reliable clean intermittent catheterization due to family unwillingness, poor social support or patient refusal. Median followup was 11.5 months (mean 48.2, range 1.3 to 144.8). Immediate postoperative complications included ileus requiring total parenteral nutrition and a wound infection in 1 patient. Long-term complications included urinary tract infection in 2 patients (febrile in 1 and positive culture for foul smelling urine in 1), stomal issues in 2 and temporary urethral leakage in 1. Constipation affected 3 children in long-term followup (all with neurogenic bowel preoperatively). Postoperative creatinine was stable or improved in all patients. CONCLUSIONS: Ileovesicostomy is a viable approach in children left with few other options, particularly those who are noncompliant or physically/socially unable to handle catheterization. This operation can help keep such patients out of diapers.
