RESUMEN
INTRODUCTION: Patients with Hirschsprung disease (HD) can experience soiling after their pull-through. We evaluated the use of antegrade continence enema (ACE) for this patient population and investigated the timing and factors associated with getting the patient clean. METHODS: We performed a single-institution retrospective review (from January 2020 to January 2023) of patients with HD and prior pull-through who had persistent soiling, failed laxative treatment or rectal enemas, and were treated with antegrade enemas. The primary outcome was time to become "clean of stool" which was defined as at least one bowel movement per day, no more than one stool accident per week, and no significant stool burden radiographically. Kaplan-Meier survival analysis was performed, and univariate cox proportional hazard regression was used to assess factors associated with time to continence. RESULTS: Thirty patients who met the criteria underwent ACE creation at a median age of 6.5 y (interquartile range 5.3-9.8) with a median follow-up time of 11.5 mo (interquartile range 5.6-16.5). Most patients became clean by 4 mo (13 of 20, 65%) with similar results at 1-y follow-up (16 of 21, 76%). The median time to becoming clean was 4.3 mo (95% confidence interval: 1.7-15.0. Patients with hypermotility were more likely to continue to soil at 1 y (80% versus 13%, P = 0.01). There were no additional factors significantly associated with time to cleanliness. CONCLUSIONS: ACE is a useful modality for HD patients with soiling. Most became clean of stool in 4 mo. The presence of hypermotility was associated with a higher incidence of persistent soiling at 1 y.
RESUMEN
INTRODUCTION: Hydronephrosis grading systems risk stratify patients with potential ureteropelvic junction obstruction, but only some criteria are measured objectively. Most notably, there is no consensus definition of renal parenchymal thinning. OBJECTIVES: The objective of this study was to assess the association between sonographic measures of renal length, renal pelvic diameter, and renal parenchymal thickness and the outcomes of a)renal hypofunction(differential renal function{DRF} <40%) and b)high-risk renal drainage(T1/2 > 40 min). STUDY DESIGN: An institutional database of patients who had diuretic renograms(DR) for unilateral hydronephrosis was reviewed. Only infants with Society for Fetal Urology(SFU) grades 3/4 hydronephrosis without hydroureter on postnatal sonogram and had a DR within 120 days were included. The following measurement variables were analyzed: anterior posterior renal pelvic diameter(APRPD), renal length(RL), renal parenchymal thickness(PT), minimal renal parenchymal thickness(MPT = shortest distance from mid-pole calyx to parenchymal edge), and renal pyramidal thickness(PyrT). RL, PT, MPT, PyrT measurements were expressed as ratios (hydronephrotic kidney/contralateral kidney). Multivariate logistic regression was performed for each outcome by comparing three separate renal measurement models. Model 1: RLR, APRPD, MPTR; Model 2: RLR, APRPD, PTR, Model 3: RLR, APRPD, PyrTR. Individual performance of variables from the best performing model were assessed via ROC curve analysis. RESULTS: 196 patients were included (107 with SFU grade 3, 89 with SFU grade 4) hydronephrosis. Median patient age was 29[IQR 16,47.2] days. 10% had hypofunction, and 20% had T1/2 > 40 min 90% with hypofunction and 87% with high-risk drainage had SFU4 hydronephrosis. Model 1 exhibited the best performance, but on multivariate analysis, only APRPD and MPTR were independently associated with both outcomes. No other measure of parenchymal thickness reached statistical significance. The odds of hypofunction and high-risk drainage increase 10% per 1 mm increase in APRPD(aOR 1.1 [CI 1.03-1.2], p = 0.005; aOR 1.1 [CI 1.03-1.2], p = 0.003). For every 0.1unit increase in MPTR the odds of hypofunction decrease by 40%(aOR 0.6 [CI 0.4-0.9], p = 0.019); and the odds of high-risk drainage decrease by 30%(aOR 0.7 [CI 0.5-0.9], p = 0.011). Optimal statistical cut-points of APRPD >16 mm and/or MPTR <0.36 identified patients at risk for obstructive parameters on DR. DISCUSSION AND CONCLUSION: Of the sonographic hydronephrosis measurement variables analyzed, only APRPD and MPTR were independently associated with objective definitions of obstruction based on renal function and drainage categories. Patients who maintain APRPD <16 mm and/or MPTR >0.36 can potentially be monitored with renal sonograms as there is >90% chance that they will not have DRF<40% or T1/2 > 40 min.
RESUMEN
BACKGROUND: Children with Spina Bifida (SB) have considerable healthcare utilization, including Emergency Department use (EDU). We aimed to elicit reasons for EDU using qualitative analysis of interviews with both patient-caregiver dyads and stakeholders. METHODS: A cohort of children with SB followed at our institution between 2016 and 2020 was identified and patient and clinical characteristics abstracted. Purposeful sampling by age and degree of past EDU was performed. Semi-structured interviews of dyads were performed using iteratively revised interview guides. Spanish-language interviews were conducted by a native Spanish speaker and transcripts professionally translated. Supplemental interviews with stakeholders, namely knowledgeable healthcare professionals, were also conducted. A qualitative framework approach was used for analysis, including open followed by closed independent coding with calculation of inter-rater reliability. A final interpretation of coding reports assessing convergence, divergence, and variation in themes across participant characteristics. RESULTS: 116 families (4 Spanish-speaking) and 7 stakeholders were interviewed. Sampling yielded a heterogenous cohort for EDU (56% with 0-10, 44% with >10 visits) and age (25% 0-4, 44% 5-11, 31% > 11 years). IRR was optimal (κ = 0.9). Themes in perceived reasons for EDU were 1) desire for "one-stop-shop" care, 2) an emergent medical problem, 3) providers' instructions, 4) negative past healthcare experience, 5) intrinsic caregiver moderators, and 6) temporospatial influences. Themes 1, 2, and 5 predominated in dyads, whereas themes 6, 3, and 5 were most common in stakeholders. Stakeholders focused largely on negative institutional and patient characteristics. Among dyads only, theme #1 was disproportionately emphasized by Spanish-speaking patients. DISCUSSION: Families desired access to coordinated expert care, testing and imaging. The ED offers this for children with SB, regardless of clinical acuity. This may be especially valued by families with inherent challenges to navigating the healthcare system. Negative experiences in community clinical settings, healthcare provider recommendations and intrinsic parental factors were themes that seemed to contribute to seeking this "one-stop-shop" type of care. Care coordination may reduce ED reliance, but themes for the interviews suggest a systems-based efforts should weave in the community care setting. CONCLUSIONS: For both stakeholders and caregivers, the ED represented a valued form of immediate access to multispecialty, expert care and testing in the context of perceived lack of timely, coordinated outpatient care. This may be moderated by intrinsic caregiver factors and negative past experiences. Although stakeholders discussed ideas that fit into patient-caregiver themes, the also uniquely focused on systems-based and patient-caregiver limitations.

OBJECTIVE: To identify factors associated with overtreatment of presumed urinary tract infection (UTI) among children with spina bifida using such criteria. STUDY DESIGN: A retrospective review of children with spina bifida (age <21 years) evaluated in the Emergency Department (ED) at a single institution was performed. Patients with a urinalysis (UA) performed who were reliant on assisted bladder emptying were included. The primary outcome was overtreatment, defined as receiving antibiotics for presumed UTI but ultimately not meeting spina bifida UTI criteria (≥2 urologic symptoms plus pyuria and urine culture growing >100k CFU/mL). The primary exposure was whether the components of the criteria available at the time of the ED visit (≥2 urologic symptoms plus pyuria) were met when antibiotics were initiated. RESULTS: Among 236 ED encounters, overtreatment occurred in 80% of cases in which antibiotics were initiated (47% of the entire cohort). Pyuria with <2 urologic symptoms was the most important factor associated with overtreatment (OR 9.6). Non-Hispanic White race was associated with decreased odds of overtreatment (OR 0.3). CONCLUSIONS: Overtreatment of presumed UTI among patients with spina bifida was common. Pyuria, which is not specific to UTI in this population, was the main driver of overtreatment. Symptoms are a cornerstone of UTI diagnosis among children with spina bifida, should be collected in a standardized manner, and considered in a decision to treat.

The treatment of patients with colorectal disorders requires care from a wide variety of medical and surgical specialties over the course of their lifetime. This is ideally handled by a collaborative center which facilitates the assessment and development of patient care among multiple specialties which can enhance the quality and implementation of treatment plans, improve communication among different specialties, decrease morbidity, and improve patient satisfaction and outcomes. This collaborative approach can serve as a model for other parts of medicine requiring a similar multi-disciplinary and integrated method of care delivery. We describe the process, as well as the lessons learned in developing such a program.
RESUMEN
OBJECTIVE: To present a unique series of children with previously repaired anorectal malformations (ARM) with subsequent urethral pathology repaired via a posterior sagittal exposure and highlight the associated technical advantages. METHODS: Using a retrospective review of all procedures performed in our pediatric colorectal and pelvic reconstruction program from January 2020 through December 2022, we compiled a case series of patients with a history of ARM and prior posterior sagittal anorectoplasty (PSARP) who had urethral pathology and concurrent indication for redo-PSARP. Clinical features, operative details, and postoperative outcomes were collected. RESULTS: Six male patients presented at a median age of 4.3 years, all born with an ARM of recto-urinary fistula type, of which 3 were recto-prostatic, 1 recto-bladder-neck, and 2 unknown type. In addition to redo-PSARP, 2 underwent remnant of the original fistula excision and 4 had urethral stricture repair. One required post-operative Heineke-Mikulicz anoplasty. Patients underwent cystoscopy 4-6 weeks post-reconstruction, and none showed urethral stricture requiring treatment. Post-procedurally, 5 patients were able to void urethrally and 1 required additional bladder augmentation/Mitrofanoff. CONCLUSION: Redo-PSARP completely mobilizes the rectum, thereby providing excellent exposure to the posterior urethra for repair. This approach also allows the option of a rectal flap for augmented urethroplasty as well as harvest of an ischiorectal fat pad for interposition.

During cloacal reconstruction, we consider both common channel (CC) and urethral length when deciding between total urogenital mobilization (TUM) and a urogenital separation (UGS). Our concern about TUM in the case of a short urethra is resultant bladder neck incompetence, while conversion to UGS after completing the TUM dissection may result in urethral injury. Use of an interposition flap harvested from the ischiorectal fossa is another measure we use to prevent potential complications.
RESUMEN
INTRODUCTION/BACKGROUND: Although the combination of bladder dysfunction and upper tract anomalies puts patient with cloaca at risk for renal disease, the rarity of this condition makes it difficult to study empirically. As a high-volume center, we uniquely capture bladder function outcomes following our growing number of cloacal repairs. OBJECTIVE: 1) Describe the rates of incomplete bladder emptying following primary cloacal repair (at 2-3 months after repair and last follow up), and 2) identify clinical factors associated with assisted bladder emptying. STUDY DESIGN: We performed a prospective cohort study of patients undergoing primary cloaca repair by our Children's National Colorectal Center team between 2020 and 2021. The primary outcome was assisted bladder emptying at 2-3 months postoperatively and last visit. Covariables included preoperative characteristics (cloacagram measurements), ARM complexity (moderate = common channel [CC] <3-cm, severe = CC ≥ 3-cm), vesicoureteral reflux (VUR) status, sacral ratio (good ≥0.7, intermediate 0.7-0.4, poor ≤0.4), spinal cord status, means of preoperative bladder emptying, and operative details (age at repair, repair type, & concomitant laparotomy). RESULTS: Eighteen participants were eligible. A majority had moderate cloaca (78%), VUR (67%), spinal cord abnormalities (89%), and good sacral ratios (56%). Preoperatively, 10 patients were diapered for urine and 8 had assisted bladder emptying. Surgical repairs were performed at a median age of 8 months (range 4-46). Nine (50%) patients underwent urogenital separation (UGS), eight (44%) total urogenital mobilization, and 1 (6%) perineal sparing posterior sagittal anorectoplasty with introitoplasty. Exploratory laparotomy was performed in 7 (39%) patients. At 2-3 months, 7 patients were voiding and 11 required assisted bladder emptying. Median length of long-term follow up was 12 months (range 5-25), and 8 patients were voiding and 10 required assisted bladder emptying. Postoperative need for assisted bladder emptying was significantly associated with assisted bladder emptying preoperatively, a shorter urethra and increasing common channel length, UGS and exploratory laparotomy. Spinal cord imaging findings were not associated. DISCUSSION: Bladder emptying following cloaca repair is likely a result of congenital function and surgical effects. Indeed, increasingly cloaca complexity requiring UGS and laparotomy was associated with both pre- and post-operative assisted bladder emptying. The lack of association with spinal cord imaging may reflect a divergence between anatomy and function. CONCLUSION: Approximately half of patients required assisted bladder emptying in this study. Associated factors included urethral and common channel length, the need for assisted bladder emptying preoperatively, the type of surgical approach and additional laparotomy. Being diapered with seemingly normal voiding prior to surgery did not guarantee normal bladder function postoperatively.

Introduction Cloacal malformations comprise a heterogeneous group of anomalies that are considered the most complex anorectal malformations (ARMs) in females. Precise evaluation to identify the unique anatomy prior to reconstruction with collaboration between colorectal surgeons, urologists, and gynecologists is vital. Here, we present a rare anatomical variation in a patient with a cloacal malformation which affected operative and postoperative management. Case description A 6-year-old female with cloaca who underwent colostomy, vaginostomy, and vesicostomy as a newborn presented for reconstruction. Her VACTERL workup was negative except for an atretic right kidney. Her ARM index included the cloaca, a normal spine, and sacrum with a lateral sacral ratio of 0.7, predicting good potential for bowel continence. Cystoscopy through the vesicostomy showed a small bladder with normal ureteral orifices, and a closed bladder neck, with no identifiable urethra. A cloacagram showed an atretic common channel, a single small vagina, and a rectum below the pubococcygeal line. The patient underwent a posterior sagittal anorectovaginourethroplasty, vaginal patch using rectum, rectoplasty, and perineal body reconstruction. The urethra was not amenable to reconstruction, so the vesicostomy was preserved and a future Mitrofanoff was planned. Conclusion Urethral atresia is a rare and challenging finding in cloaca patients, and a vesicostomy is needed to drain urine in the newborn period. Preoperative examination under anesthesia, cystoscopy, vaginoscopy, and cloacagram are crucial to identify the precise anatomy and to plan accordingly.
RESUMEN
We present a case of a rare complication in a 10-month-old female referred to our institution for an anal stricture after primary cloacal repair as an infant. Multimodal imaging, careful physical exam, and endoscopic evaluation revealed her vagina had been pulled through to the location of her anal sphincter muscle complex. We describe the correction of this problem, including identification of her rectum.
RESUMEN
Cloaca is a rare, complex malformation encompassing the genitourinary and anorectal tract of the female in which these tracts fail to separate in utero, resulting in a single perineal orifice. Prenatal sonography detects a few cases with findings such as renal and urinary tract malformations, intraluminal calcifications, dilated bowel, ambiguous genitalia, a cystic pelvic mass, or identification of other associated anomalies prompting further imaging. Multi-disciplinary collaboration between neonatology, pediatric surgery, urology, and gynecology is paramount to achieving safe outcomes. Perinatal evaluation and management may include treatment of cardiopulmonary and renal anomalies, administration of prophylactic antibiotics, ensuring egress of urine and evaluation of hydronephrosis, drainage of a hydrocolpos, and creation of a colostomy for stool diversion. Additional imaging of the spinal cord and sacrum are obtained to plan possible neurosurgical intervention as well as prognostication of future bladder and bowel control. Endoscopic evaluation and cloacagram, followed by primary reconstruction, are performed by a multidisciplinary team outside of the neonatal period. Long-term multidisciplinary follow-up is essential given the increased rates of renal disease, neuropathic bladder, tethered cord syndrome, and stooling issues. Patients and families will also require support through the functional and psychosocial changes in puberty, adolescence, and young adulthood.
RESUMEN
INTRODUCTION AND OBJECTIVE: Prior studies have shown a broad half time (T1/2) interval on MAG3 diuresis renography (DR) that is indeterminate for obstruction. We aimed to refine and sub-divide the indeterminate range and associate it with clinically meaningful outcomes: pyeloplasty and pyeloplasty-free survival. METHODS: We identified patients <1.5 years-old at presentation with unilateral, isolated moderate to severe hydronephrosis who underwent DR from 2000 to 2016. A logistic regression model was created using T1/2 to predict surgery. An indeterminate range was defined based on patients with <90% probability of pyeloplasty or resolution. This group was sub-divided into three T1/2 intervals: 5-20, 21-40, and 41-60 min. Endpoints were pyeloplasty and pyeloplasty free survival. Indications for surgery were loss of differential renal function (DRF), worsening T1/2, family preference, and/or pain. RESULTS: Among 2025 patients with DR, 704 met criteria (169 were lost to follow up). Of the remaining 535, 218 had pyeloplasties and 317 did not. The Pyeloplasty group had significantly worse DRF, T1/2 at initial DR, and exited the study earlier, at a median age 1.1years vs 2.3 years (p < 0.001). For all patients with antenatally detected unilateral UPJ obstruction, the odds of undergoing pyeloplasty at any time increased by 1.8 times (p < 0.001 [95% CI: 1.04, 1.08]) per 10 unit increase in T1/2 until T1/2 = 60. However, in patients with intermediate drainage, five year surgery-free survival probability for patients with T1/2 5-20, 21-40, and 41-60 min were 79.7%, 46.7% and 33.3% respectively (χ2 = 41.2, P = <0.001). DISCUSSION: Previous efforts to define indeterminate drainage resulted in ranges for T1/2 that were too broad to be clinically useful. Within our endpoint-defined indeterminate range, our data show that there are significant step offs in 5-year surgery-free survival for patients with T1/2 < 20 min, 21-40 min, and 41-60 min. Although there is a steady decrease in surgery-free survival among patients with a T1/2 of 21-40 min over the first 5 years of life, half can be managed nonoperatively. These patients likely represent the true intermediate risk group and closer follow up is justified. CONCLUSIONS: Initial T1/2 on DR is predictive of future surgery. When drainage is "indeterminate" for obstruction, sub-stratification allows for more accurate prognostication.

PURPOSE: Recent studies have demonstrated trends of decreasing voiding cystourethrogram utilization rates and delayed vesicoureteral reflux diagnosis in some children. It is possible that such delays could lead to more children sustaining repeated episodes of febrile urinary tract infection, and potential kidney injury, prior to diagnosis and treatment. MATERIALS AND METHODS: Using single institutional, cross-sectional cohorts of patients in 2 time periods (2005 and 2015), we compared clinical presentation and renal outcomes among patients 13 years and younger with history of febrile urinary tract infection presenting for initial voiding cystourethrogram. Outcomes included 1) recurrent urinary tract infection, 2) presence of vesicoureteral reflux, 3) grade of vesicoureteral reflux, and 4) renal scarring. Associations between year of presentation and outcomes of recurrent urinary tract infection and vesicoureteral reflux diagnosis were evaluated using multivariable logistic regression models. For the outcome of renal scarring, a logistic regression model was fitted for propensity score matched cohorts. RESULTS: Compared to children presenting in 2005, those in 2015 had 3 times the odds of recurrent urinary tract infection (OR 3.01, 95% CI 2.18-4.16, p <0.0001). Time period was not associated with the odds of vesicoureteral reflux (OR 0.98, 95% CI 0.77-1.23, p=0.85). Those in 2015 were more likely to present with vesicoureteral reflux grade >3 (OR 2.22, 95% CI 1.13-4.34, p=0.02) but not vesicoureteral reflux grade >2 (OR 1.11, 95% CI 0.74-1.67, p=0.60). Renal scarring was more common among children presenting in 2015 (OR 2.9, 95% CI 1.03-8.20, p=0.04). CONCLUSIONS: Compared to 2005, children presenting in 2015 for post-urinary tract infection voiding cystourethrogram have increased likelihood of recurrent urinary tract infection and renal scarring, despite similar likelihood of vesicoureteral reflux diagnosis.

PURPOSE: For postoperative visits, which are often brief interactions between family and clinician, patients may prefer the convenience of receiving postoperative care from home. We evaluated the feasibility of telemedicine for postoperative encounters in pediatric urology. MATERIALS AND METHODS: We performed a prospective telemedicine pilot study during an implementation period from November 10, 2017 to March 22, 2018. All postoperative patients deemed eligible by 1 of 4 urologists were offered enrollment in the telemedicine program. Enrollees underwent at least 1 virtual visit within 6 weeks of surgery. Technical difficulties and the number of unscheduled visits and readmissions were noted. After each virtual evaluation the family and clinician were prompted to complete a survey pertaining to perceptions of the telemedicine experience, including how effective the virtual visit was in delivering care. For each virtual visit with a urologist we estimated roundtrip travel cost and time. RESULTS: There was 96% technical success when using the software. A total of 125 postoperative virtual visits were completed in 83 patients. Median age of the children was 3.4 years and 87% were boys. Clinicians found that the virtual visit was "very effective" in 86% of cases, delivering the same care that they would have provided during a visit in person. Families were estimated to have saved a mean $150 travel cost and a median of 113 minutes of travel time per visit. No adverse postoperative outcomes were observed. CONCLUSIONS: This pilot study demonstrates that telemedicine can be successfully implemented in the postoperative care of pediatric urology patients.

Due to the rarity of the disease, adverse events related to ejaculatory function following the management of paratesticular rhabdomyosarcoma with multimodal therapy in adolescents are rarely discussed. Two patients, age 14 and 15 at time of diagnosis were treated with multimodal therapy with nerve-sparing retroperitoneal lymph node dissection, chemotherapy, and radiotherapy. Each developed ejaculatory dysfunction during the treatment period, which resolved 1 year after completion of all therapies. We sought to assess the role of each component of multimodal therapy on the observed side effect and the potential for delayed recovery of function after cessation of all therapies.
