RESUMO
BACKGROUND: Obstructive uropathy (OU) is a leading cause of pediatric kidney injury. Accurate prediction of kidney disease progression may improve clinical outcomes. We aimed to examine discrimination and accuracy of a validated kidney failure risk equation (KFRE), previously developed in adults, in children with OU. METHODS: We identified 118 children with OU and an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 in the Chronic Kidney Disease in Children study, a national, longitudinal, observational cohort. Each patient's 5-year risk of kidney failure was estimated using baseline data and published parameters for the 4- and 8-variable KFREs. Discriminative ability of the KFRE was estimated using the C statistic for time-to-event analysis. Sensitivity and specificity were evaluated across varying risk thresholds. RESULTS: Among the 118 children, 100 (85%) were boys, with median baseline age of 10 years (interquartile range, 6-14). Median eGFR was 42 mL/min/1.73m 2 (32-53), with a median follow-up duration of 4.5 years (2.7-7.2); 23 patients (19.5%) developed kidney failure within 5 years. The 4-variable KFRE discriminated kidney failure risk with a C statistic of 0.75 (95% CI, 0.68-0.82). A 4-variable risk threshold of ≥ 30% yielded 82.6% sensitivity and 75.0% specificity. Results were similar using the 8-variable KFRE. CONCLUSIONS: In children with OU, the KFRE discriminated the 5-year risk of kidney failure at C statistic values lower than previously published in adults but comparable with suboptimal values reported in the overall CKiD population. The 8-variable equation did not improve model discrimination or accuracy, suggesting the need for continued research into additional, disease-specific markers.

BACKGROUND: A growing number of tertiary children's hospitals are utilizing robotic surgical technology. We sought to characterize national trends in pediatric surgical robotic case utilization and related drivers. METHODS: Pediatric urology and pediatric surgery (abdominal and thoracic) procedures, performed from January 2010 to December 2019 across 19 U.S. tertiary care children's hospitals, were identified using the Pediatric Health Information System (PHIS). Trends in robot utilization were evaluated by surgical subspecialty, procedure type, and number of individual operating surgeons. RESULTS: Increases were noted in the overall numbers of pediatric surgery (1.3% per quarter, p = 0.005) and urology robotic procedures (2.0% per quarter, p < 0.001), as well as the numbers of pediatric surgeons (7.5% per year, p < 0.001) and pediatric urologists (7.8% per year, p < 0.001) operating robotically. Biliary system and spleen surgery were the most common robotic pediatric surgery procedures (45.5%) and had stable utilization over time (- 0.8% per quarter, 95% CI - 2.3-0.8). Robotic foregut surgery showed the most rapid growth in utilization (2.1% per quarter, 95% CI 0.7-3.6, p = 0.004) in pediatric surgery, while mediastinal/thoracic surgery demonstrated a decrease in utilization (- 4.6%, 95% CI - 7.9-1.2, p = 0.008). Renal pelvis/ureter surgery was the most common robotic urologic procedure (55.8%) and also demonstrated the fastest growth utilization (2.2% per quarter, 95% CI 1.5-2.9, p < 0.001) in urology. CONCLUSIONS: Utilization of robotic-assisted surgery in pediatric surgery and pediatric urology has increased both in case volume and the number of operating surgeons, with foregut and renal pelvis/ureter surgery responsible for the areas of greatest growth.

BACKGROUND: Congenital obstructive uropathy (OU) is a leading cause of pediatric kidney failure, representing a unique mechanism of injury, in part from renal tubular stretch and ischemia. Tubular injury biomarkers have potential to improve OU-specific risk stratification. METHODS: Patients with OU were identified in the Chronic Kidney Disease in Children (CKiD) study. "Cases" were defined as individuals receiving any kidney replacement therapy (KRT), while "controls" were age- and time-on-study matched and KRT free at last study visit. Urine and plasma neutrophil gelatinase-associated lipocalin (NGAL), interleukin 18 (IL-18), and liver-type fatty acid-binding protein (L-FABP) levels were measured at enrollment and annually and compared between cases and controls. Urine values were normalized to urine creatinine. RESULTS: In total, 22 cases and 22 controls were identified, with median (interquartile range) ages of 10.5 (9.0-13.0) and 15.9 (13.9-16.9) years at baseline and outcome, respectively. At enrollment there were no differences noted between cases and controls for any urine (u) or plasma (p) biomarker measured. However, the mean pNGAL and uL-FABP/creatinine increased throughout the study period in cases (15.38 ng/ml per year and 0.20 ng/ml per mg/dl per year, respectively, p = 0.01 for both) but remained stable in controls. This remained constant after controlling for baseline glomerular filtration rate (GFR). CONCLUSIONS: In children with OU, pNGAL and uL-FABP levels increased over the 5 years preceding KRT; independent of baseline GFR. Future studies are necessary to identify optimal cutoff values and to determine if these markers outperform current clinical predictors.

BACKGROUND: Obstructive uropathy (OU) is a common cause of end-stage renal disease (ESRD) in children. Children who escape the newborn period with mild-to-moderate chronic kidney disease (CKD) continue to be at increased risk. The predictive ability of clinically available markers throughout childhood is poorly defined. METHODS: Patients with OU were identified in the Chronic Kidney Disease in Children Study. The primary outcome of interest was renal replacement therapy (RRT) (cases). Controls were age matched and defined as patients within the OU cohort who did not require RRT during study follow-up. RESULTS: In total, 27 cases and 41 age-matched controls were identified. Median age at baseline and age at outcome measurement were 10 vs. 16 years, respectively. First available glomerular filtration rate (GFR) (36.9 vs. 53.5 mL/min per 1.73 m2), urine protein/creatinine (Cr) (0.40 vs. 0.22 mg/mg) and microalbumin/Cr (0.58 vs. 0.03 mg/mg), and serum CO2 (20 vs. 22 mmol/L) and hemoglobin (12.4 vs. 13.2 g/dL) differed significantly between cases and controls, respectively. GFR declined 3.07 mL/min per 1.73 m2/year faster in cases compared to that in controls (p < 0.0001). Urine protein/Cr and microalbumin/Cr increased by 0.16 and 0.11 per year more in cases compared to those in controls, respectively (p ≤ 0.001 for both). Serum phosphate increased by 0.11 mg/dL and serum albumin and hemoglobin decreased by 0.04 (g/dL) and 0.14 (g/dL) per year more for cases compared to those for controls, respectively (p < 0.05 for all). CONCLUSIONS: Age-specific baseline and longitudinal measures of readily available clinical measures predict progression to ESRD in children with mild-to-moderate CKD from OU.

BACKGROUND: Chemotherapy is used preoperatively for children with bilateral Wilms tumor (BWT) or unilateral high-risk Wilms tumor (UHRWT) to promote tumor regression to facilitate renal preservation with nephron-sparing surgery (NSS). In adults, various surgical techniques have been described to preserve renal tissue. Few studies have examined the use of surgical adjuncts in NSS in children with renal tumors. METHODS: We performed a multi-institutional retrospective review of patients with BWT or UHRWT. Patient demographics, tumor size at diagnosis, following neoadjuvant chemotherapy, utilization of surgical adjuncts including intraoperative ultrasound (IOUS), margin status, complications, renal function, and follow-up were recorded. RESULTS: The cohort comprised 23 patients: 18 BWT, 3 UHRWT, and 2 patients with solitary kidney. Twenty-two of the 23 patients had successful NSS. IOUS was used 19 times, and seven had positive margins after surgery. Cooling/vascular isolation was used six times. At a median follow-up of 18 mo, median estimated glomerular filtration rate Schwartz was 126 mL/min/1.73 m2 and median serum creatinine 0.39 mg/dL in the 22 patients who had successful NSS. There have been no tumor recurrences. CONCLUSIONS: In patients with BWT and UHRWT, surgical adjuncts such as cooling/vascular isolation are uncommonly performed. IOUS may be helpful but does not guarantee negative microscopic margins. LEVEL OF EVIDENCE: Level 4, Case series with no comparison group.

PURPOSE: The 2011 American Academy of Pediatrics clinical practice guideline for childhood febrile urinary tract infection recommends voiding cystourethrography if renal and bladder ultrasound reveals hydronephrosis, scarring or "other findings" that suggest high grade vesicoureteral reflux. We sought to determine if the finding of uroepithelial thickening indicates greater risk of high grade vesicoureteral reflux and whether uroepithelial thickening improves the screening value of renal and bladder ultrasound. MATERIALS AND METHODS: We retrospectively analyzed renal and bladder ultrasound and voiding cystourethrogram findings in children 2 to 24 months old with first febrile urinary tract infection during an 11-year period. Patients with uroepithelial thickening were compared to an age and gender matched sample without uroepithelial thickening. Logistic regression was used to identify factors associated with high grade vesicoureteral reflux. Test characteristics of renal and bladder ultrasound for high grade reflux were compared based on different criteria to define an abnormal renal and bladder ultrasound. RESULTS: Of 226 patients 143 (63%) had vesicoureteral reflux, of whom 37 (26%) had high grade reflux. On multivariable analysis uroepithelial thickening was a significant independent predictor of high grade vesicoureteral reflux (OR 5.41, 95% CI 1.74-16.79, p = 0.004). When hydronephrosis and hydroureter were considered the only abnormal renal and bladder ultrasound findings warranting voiding cystourethrography, sensitivity of renal and bladder ultrasound for high grade reflux was 84%, and 6 children with high grade and 82 with low grade reflux would have been missed. When uroepithelial thickening was also considered an abnormal finding, the sensitivity increased to 97%, and only 1 child with high grade and 57 with low grade reflux would have been missed. CONCLUSIONS: Uroepithelial thickening is associated with an increased risk of high grade vesicoureteral reflux and is an abnormal finding warranting voiding cystourethrography. Sensitivity of renal and bladder ultrasound as a screening test for high grade vesicoureteral reflux is markedly improved when uroepithelial thickening is considered.

BACKGROUND: To evaluate utilization and costs associated with robotic surgery in children. MATERIALS AND METHODS: We identified patients in the Pediatric Health Information System database who underwent robotic surgery between October 2008 and December 2013. After determining the six most frequently performed surgeries in this group, we identified patients who underwent equivalent nonrobotic surgeries at the same hospitals. Equivalent surgeries were defined as open procedures for urology and laparoscopic procedures for general surgery. We examined trends in the numbers of surgeries performed and compared hospitalization costs between patients undergoing elective robotic and nonrobotic surgery for each procedure. RESULTS: The number of robotic surgeries performed increased by 19.8% per year (P < 0.001). The most common robotic surgeries performed were pyeloplasty (n = 760), ureteral reimplantation (n = 351), nephrectomy (n = 145), partial nephrectomy (n = 56), gastrointestinal antireflux procedure (n = 61), and cholecystectomy (n = 46). Total increase over time was primarily driven by increases in urologic surgeries (17.4% per year, P < 0.001). Postoperative length of stay was shorter after robotic surgeries than equivalent open urologic surgeries but not equivalent laparoscopic general surgery procedures. Total hospitalization costs were higher for robotic surgeries than equivalent urologic or general surgery procedures. CONCLUSIONS: Use of robotic surgery in pediatrics is increasing especially in the management of urologic conditions. Costs of robotic surgery-associated hospitalizations were higher than nonrobotic surgery-associated hospitalizations.

OBJECTIVE: To improve the predictive ability of diuretic renography (DR) for surgical intervention in children with congenital hydronephrosis (CH) and concern for ureteropelvic junction obstruction. METHODS: Children with CH born between 2007 and 2021 who underwent initial DR prior to 6months of life, had both clearance while upright (CUP) and T ½ reported, and did not have immediate surgical intervention after the first DR were retrospectively evaluated for surgical intervention during the period of clinical observation. Once the optimal cut-points were identified for CUP and T ½, they were used to calculate the sensitivity, specificity, positive predictive value, and negative predictive value. RESULTS: In total 65 patients were included in the final analysis with 33 (50.8%) undergoing surgical intervention (pyeloplasty) and 32 (49.2%) still on observation at last follow-up. The optimal cut-points for predicting surgical intervention were 28.1 minutes for T ½ and 22.4% for CUP. Applying the CUP cut-point of 22.4% we achieved a sensitivity of 60.6% (95% CI: 43.9-77.3), specificity of 96.9% (95% CI: 90.1-100.0), positive predictive value of 95.2% (95% CI: 86.1-100.0), and negative predictive value of 70.5% (95% CI: 57.0-83.9). CONCLUSION: A low CUP accurately predicts surgical intervention in children with CH who are initially observed. Although there is no singular measure on DR that can with absolute certainty predict future clinical course, our data do suggest there is utility in incorporating CUP (if <22.4%) into the decision process. Further research is necessary to help guide the management of children with intermediate CUP values.

PURPOSE: This study aimed to analyze organ system-based causes and non-organ system-based mechanisms of death (COD, MOD) in people with myelomeningocele (MMC), comparing urological to other COD. METHODS: A retrospective review was performed of 16 institutions in Canada/United States of non-random convenience sample of people with MMC (born > = 1972) using non-parametric statistics. RESULTS: Of 293 deaths (89% shunted hydrocephalus), 12% occurred in infancy, 35% in childhood, and 53% in adulthood (documented COD: 74%). For 261 shunted individuals, leading COD were neurological (21%) and pulmonary (17%), and leading MOD were infections (34%, including shunt infections: 4%) and non-infectious shunt malfunctions (14%). For 32 unshunted individuals, leading COD were pulmonary (34%) and cardiovascular (13%), and leading MOD were infections (38%) and non-infectious pulmonary (16%). COD and MOD varied by shunt status and age (p < = 0.04), not ambulation or birthyear (p > = 0.16). Urology-related deaths (urosepsis, renal failure, hematuria, bladder perforation/cancer: 10%) were more likely in females (p = 0.01), independent of age, shunt, or ambulatory status (p > = 0.40). COD/MOD were independent of bladder augmentation (p = >0.11). Unexplained deaths while asleep (4%) were independent of age, shunt status, and epilepsy (p >= 0.47). CONCLUSION: COD varied by shunt status. Leading MOD were infectious. Urology-related deaths (10%) were independent of shunt status; 26% of COD were unknown. Life-long multidisciplinary care and accurate mortality documentation are needed.

INTRODUCTION: Office circumcision with a clamp or Plastibell device is often restricted in practice by patient age and size. This is thought to ensure the patient fits appropriately on the restraining device and limit complications. OBJECTIVE: To compare the outcomes of office circumcision in children ≤3 months of age and ≤5.1 kg in weight to those who do not fit this criterion. STUDY DESIGN: A retrospective chart review was performed of all office circumcisions in children ≤6 months of age performed in our urology clinic between January 2015-August 2018. Patients were divided into two groups: Group 1 (≤3 months old and ≤5.1 kg) and Group 2 (all others). Patient demographics and circumcision technique were recorded. The number of patients with complications and requiring an intervention related to circumcision were compared between groups, as well as the number of patients requiring unplanned hospital visits. Differences in outcomes were evaluated using Pearson's chi-square test. RESULTS: A total of 205 circumcisions were performed in Group 1 and 498 circumcisions were performed in Group 2. All circumcisions were performed by either Gomco clamp or Plastibell device with no significant difference in method between groups (p = 0.5). There was no difference in median follow-up between groups (Group 1: 19 days [IQR 14; 34]; Group 2: 19 days [IQR 14; 36]; p = 0.6). There were no significant differences between groups in the number patients with complications or requiring an intervention (p = 0.08 and p = 0.12, respectively). Significantly more patients in Group 2 required an unplanned hospital visit (p = 0.02) (Table). After categorizing those composing Group 2 into three disjoint sets (children >3 months and ≤5.1 kg, or ≤3 months and >5.1 kg, or >3 months and >5.1 kg), no significant difference across all four groups in regards to complications (p = 0.12) or intervention (p = 0.2) was found. There was a significant difference in unplanned hospital visits (p < 0.001). DISCUSSION: Performing office circumcisions in children outside of age and weight restrictions of ≤3 months and ≤5.1 kg did not significantly increase the risk of complications or need for interventions. Those outside of age and weight restrictions, however, had more unplanned hospital visits. Tailoring parent expectations in this patient group may be needed. CONCLUSIONS: While we found older and heavier children had more unplanned post-procedural related hospital visits, their rates of overall complications and need for subsequent interventions were not significantly higher than younger and lighter children.

OBJECTIVE: To describe and evaluate efficacy of a more practical, at-home regimen of parasacral transcutaneous electrical nerve stimulation (TENS) for pediatric overactive bladder (OAB). METHODS: We prospectively enrolled patients with OAB. INCLUSION CRITERIA: age 5-13 years and willingness to try TENS. EXCLUSION CRITERIA: urinary tract anatomic abnormalities, current use of OAB medications, neurologic condition, and elevated post-void residual. Patients were instructed to complete 20-minute sessions 2x/day for 1 month. Patients completed the Vancouver Symptom Score (VSS) and 48-hour frequency-volume chart before/after treatment. Compliance was assessed with a daily log. We recorded patient-reported improvement. Primary outcome was difference in VSS before/after treatment; secondary outcomes included: differences in frequency of voids/24 hours, max voided volume in 48 hours (%EBC), mean voided volume (%EBC), and mean number incontinence episodes/24 hours. RESULTS: We enrolled 21 patients (3 male, 18 female; median age 9.9 years). We had complete VSS data on 17 patients and frequency-volume chart data on 12 patients. Median % of TENS sessions completed was 98%. 8/17 patients reported subjective improvement. There was a significant difference between pre- and post-TENS VSS (median score: 23 pre-TENS and 21 post-TENS, P = .009). There were no differences in secondary outcomes before/after treatment. CONCLUSION: In our cohort of medically-refractory OAB pediatric patients, nearly half reported subjective improvement with our regimen, despite modest objective improvement. Our compliance rates suggest this regimen is practical but may be best used as an adjunct to other therapies.

Robot-assisted laparoscopic surgery (RALS) has recently been described in children < 1 year old. However, little data exist on robotic utilization in infants ≤ 6 months old, likely due to concerns for limited intraabdominal space and decreased distance between ports in this cohort. We hypothesized that the robotic approach can be successfully used for infants ≤ 6 months old. A prospectively collected database of patients undergoing urologic robotic surgery at our institution was reviewed. Patients ≤ 6 months and ≥ 4 kg were included. Patient demographics, intraoperative details, hospital length of stay, and complications were reviewed. Descriptive statistics were performed. Twelve patients ≤ 6 months old underwent urologic robotic surgery by three surgeons at our institution (2013-2019): pyeloplasty (6), ureteroureterostomy (4), heminephrectomy (1), and nephrectomy (1). Median age at surgery was 4.75 months (IQR 4, 6). Median weight was 7.09 kg (IQR 6.33, 7.78). Median console time was 105 min (IQR 86, 123). For all procedures, 8-mm robotic arm ports were used. No procedures were converted to open. Median post-operative hospital stay was 24 h (IQR). Febrile UTI was the only complication occurring within 30 days of surgery (n = 4, 33%; 7-20 days, Clavien grade 2). For those undergoing pyeloplasty or ureteroureterostomy (n = 10), postoperative ultrasound showed improved (n = 9) or stable hydronephrosis (n = 1). At a median follow-up of 19.73 months (IQR 4.27, 38.32), no patient required an unplanned secondary intervention. Robotic upper urinary tract surgery is feasible and safe in patients ≤ 6 months of age and can be performed successfully with the same technique as for older children.

INTRODUCTION: Gomco clamp and Plastibell ring are common methods of office circumcision. While they possess similar features, the Plastibell is retained after the procedure which could impact perceived and true outcomes of the procedure. OBJECTIVE: This study evaluated differences in complications, interventions, and healthcare utilization between Gomco and Plastibell office circumcision techniques. STUDY DESIGN: We retrospectively reviewed urology office performed circumcisions (January 2015-August 2018), limiting analysis to patients with follow-up. Patient demographics and circumcision technique were recorded. Complications, interventions, phone calls, emergency department (ED)/urgent care (UC) visits, and unplanned office visits directly related to the circumcision were recorded. Descriptive statistics for the number of patients experiencing an event and the number of days to event were summarized. Survival analysis with inverse probability of treatment weights was used to estimate hazard and incidence rate ratios (HR and IRR, respectively). RESULTS: 746 patients were included for analysis. Median time of follow-up was 2.7 weeks (interquartile range 2-5). 257 (34%) patients underwent Gomco circumcision; 489 (66%) underwent Plastibell circumcision. The techniques did not significantly differ for complications (HR = 0.9, p = 0.497), interventions (HR = 0.89, p = 0.498), and hospital visits (HR = 1.0, p = 0.985) (Table), although Plastibell patients presented to the ED/UC more (odds ratio = 1.6, p = 0.02). Plastibell patients generated proportionally more post-procedural phone calls (63 vs. 52%), though not significantly (IRR = 1.11; p = 0.426). DISCUSSION: Overall, the type of device used for office circumcision, between Gomco clamp and Plastibell ring, does not appear to impact the outcome of circumcision. Providers should perform the method of office circumcision with which they are familiar and comfortable. There is an overall reliance on healthcare resources suggesting poor family preparation of the post-procedural course regardless of the technique, necessitating better patient education. Limitations of this study include its retrospective nature, variability in follow-up between techniques, and variety of providers, limited to pediatric urologists, performing circumcision. CONCLUSIONS: Gomco and Plastibell office circumcision techniques do not significantly differ in post-procedural complications, interventions, unplanned hospital visits, and office phone calls. Plastibell patients do present more often to the ED/UC perhaps as a result of increased anxiety and perceived immediacy of concerns with the device.

The objective of this study is to determine recent trends in use of robotics and laparoscopy for pediatric retroperitoneal lymph-node dissection (RPLND) in pediatric and non-pediatric hospitals. We conducted a retrospective cohort study using data from 29 hospitals in the Pediatric Health Information System (PHIS), and data from 14 states in the State Inpatient Databases (SID), between 2008 and 2014. The study population was comprised of patients aged ≥ 10 years undergoing RPLND, with an inpatient diagnosis of testicular or paratesticular cancer, based on international classification of disease (ICD) codes. Robotic approach was identified by the presence of an ICD procedure code modifier. During the study period, a total of 90 RPLNDs were performed in pediatric hospitals (median patient age 16 years). Of these, 4 (4.4%) were performed robotically. A total of 3120 RPLNDs were performed in non-pediatric hospitals (median patient age: 32 years). Among these, 269 (8.6%) were performed robotically, with an increasing trend in the use of robotic RPLND (adjusted annual increase in probability of undergoing robotic vs. open procedure: 16%; 95% CI 8-24). Undergoing robotic RPLND was associated with a reduction in postoperative length of stay of 3.5 days (95% CI 2.9, 4.1). Open surgical approaches comprise the vast majority of RPLNDs performed at pediatric hospitals. This is in contrast with trends in non-pediatric hospitals where robotic RPLND is being increasingly utilized. Future research is necessary to investigate this discrepancy in adopting minimally invasive techniques for RPLND in pediatric centers.

OBJECTIVE: To understand the utilization of augmentation cystoplasty (AC) for the management of neurogenic bladder in children with myelomeningocele (MMC). AC carries considerable risk. To mitigate this, recent studies have emphasized alternatives to AC, but it is unknown if these interventions have resulted in fewer ACs being performed. Our goal was to evaluate the use of AC in MMC patients over the past decade. We hypothesized that the use of AC had decreased and that the age at AC increased. METHODS: Using the Pediatric Health Information System, we studied patients with MMC who had an AC between January 2009 and December 2018. International Classification of Disease procedure codes were used to identify AC procedures. We quantified trends in AC utilization by estimating the annual proportion of MMC admissions with an AC. We also assessed trends in patient age at the time of AC. RESULTS: Proportion of AC per MMC admissions across the study period was 4.8%. There was no significant annual trend in the overall number of ACs performed each quarter over the past decade nor was there any change in the estimated annual incidence rate ratio of AC (1.01, 95% confidence interval 0.96, 1.05; P =.75). The estimated annual change in patient age at procedure remained relatively constant over the study period (-0.03 years, 95% confidence interval -0.13, 0.07; P = .51). CONCLUSION: Practice patterns for the utilization of AC in MMC did not change significantly over the past decade despite prominent voices in the literature emphasizing alternative interventions in this patient population.

INTRODUCTION: Minimally invasive (robotic and pure laparoscopic) pyeloplasty has been increasingly used for treatment of ureteropelvic junction obstruction (UPJO). However, few large-scale studies have compared these two modalities directly. METHODS: We performed a retrospective single-center review of all patients who underwent pure laparoscopic (LP) or robotic pyeloplasty (RALP) between 2007 and 2018. Patients were excluded if the initial surgery at our institution was a redo pyeloplasty or if they lacked follow-up information. Outcomes of interest included operative time, length of stay, and complication rates, including rates of secondary procedures. We compared these outcomes between groups using Student's t test for continuous variables and a Chi-square for categorical variables. RESULTS: A total of 282 patients were identified. Forty-eight were excluded based on study criteria; therefore, our total study cohort was 234 patients: 119 RALP and 115 LP cases. Overall mean postoperative follow-up time was 20.8 months, with no significant differences between groups. Mean operative time was shorter in the LP group when compared the RALP group (3 h 7 min vs. 3 h 41 min, p < 0.001). There were no significant differences between groups in length of stay (1.22 days vs 1.50 days, p = 0.095). Complications occurred in 52 patients (22.2% of overall cohort) with no difference in incidence between groups. Twenty-five patients (14 in the RALP group and 11 in the LP group) underwent unplanned secondary procedures; 19 of these patients (9 in the RALP group and 10 in the LP group) needed a procedure to address secondary obstruction. CONCLUSION: We demonstrated no significant differences between RALP and LP in regards to complication rates. Surgeons performing RALP and LP have the potential to offer the same level of care for the surgical management of UPJO, especially in countries where robotic technology may not be readily available.

OBJECTIVE: To investigate the role of albuminuria as a clinical marker of early renal disease in children with neurogenic bladder (NGB) in association with commonly used predictors of renal risk. METHODS: Catheterized urine was obtained from 40 patients with NGB at a tertiary pediatric hospital. Albumin-to-creatinine ratio (ACR) was analyzed for associations with estimated glomerular filtration rate, vesicoureteral reflux, hydronephrosis, bladder dynamics, and renal scarring. RESULTS: About 32% (13/40) of NGB patients had elevated ACR (≥30 mg/g. Elevated ACR was associated with Caucasian race, clean intermittent catheterization, hydronephrosis, and vesicoureteral reflux on univariate analysis. In multivariable analysis, presence of vesicoureteral reflux and use of anticholinergic medication were significant predictors of ACR elevation. CONCLUSION: Albuminuria is an established clinical predictor of renal disease and risk for progression to renal failure. The presence of albuminuria in NGB patients with urinary tract abnormalities suggests these patients may be at increased risk for progressive renal disease. This supports the clinical utility of adding ACR to the evaluation of renal risk in pediatric NGB.

OBJECTIVES: Posterior urethral valves predispose children to renal replacement therapy (RRT) and bladder dysfunction. Researchers of single-institutional series were unable to refine risk stratification because of rarity of the disease. We aimed to identify clinical variables associated with the risk of RRT and clean intermittent catheterization (CIC) in a large multicenter cohort study. METHODS: Children with posterior urethral valves born between 1995 and 2005 who were treated before 90 days of life at 5 children's hospitals were retrospectively reviewed. Outcomes included RRT and recommendation for CIC. Predictors and outcomes were assessed by using survival analysis. RESULTS: A total of 274 patients were managed for a median of 6.3 years, and 42 progressed to RRT. On survival analysis, 16% progressed to RRT by 10 years of age. RRT varied by the serum nadir creatinine level in the first year of life (SNC1) (log-rank P < .001). After stratifying by the SNC1, the estimated risk of progressing to RRT by 10 years of age was 0%, 2%, 27%, and 100% for an SNC1 of <0.4, an SNC1 of 0.4 to 0.69, an SNC1 of 0.7 to 0.99, and an SNC1 of ≥1.0 mg/dL, respectively. CIC was recommended in 60 patients, which translated on survival analysis to a risk of 26% by 10 years of age. CONCLUSIONS: Risk of RRT and CIC recommendation increased with age. The SNC1 strongly predicted need for RRT. These results allow for both improved family counseling and the potential for more appropriate screening and intervention strategies for those identified in higher-risk groups.

IMPORTANCE: Although opioids are an important component of pain management for children recovering from surgery, postoperative opioid prescribing has contributed to the current opioid crisis in the United States because these medications are often prescribed in excess and are rarely properly disposed. One potential strategy to combat opioid misuse is to remove excess postoperative opioids from circulation by providing patients with drug disposal products that enable safe disposal of opioids in the home garbage. OBJECTIVE: To determine whether the provision of a drug disposal bag increases proper opioid disposal among the families of pediatric patients undergoing ambulatory surgery. DESIGN, SETTING, AND PARTICIPANTS: This randomized clinical trial enrolled 202 parents or guardians of children 1 to 17 years of age who underwent otolaryngologic or urologic surgery at the outpatient surgery centers of a tertiary children's hospital in Columbus, Ohio, from June to December 2018 and who received an opioid prescription prior to discharge. INTERVENTIONS: Families randomized to intervention were provided a drug disposal bag containing activated charcoal and instructions for use plus standard postoperative discharge instructions on opioid use, storage, and disposal. Families in standard care arm received standard postoperative discharge instructions only. All participants completed a baseline survey and a follow-up survey 2 to 4 weeks postoperatively. MAIN OUTCOMES AND MEASURES: Primary outcome was proper opioid disposal, defined as disposal using a drug disposal bag or a disposal method recommended by the US Food and Drug Administration. RESULTS: Of 202 parents or guardians enrolled, 181 completed follow-up (92 in intervention arm and 89 in standard care arm). Most patients in both groups were white (75 [73.5%] vs 79 [80.6%]) and male (63 [61.2%] vs 54 [54.6%]), and the median (interquartile range) age was 6 (5-9) years in the intervention arm and 7 (6-10) years in the standard care arm. For intention-to-treat analyses, 92 families receiving a disposal bag and 89 families not receiving a disposal bag were included. Among them, 66 families (71.7%) randomized to receive a disposal bag reported properly disposing of their child's opioids, whereas 50 parents (56.2%) who did not receive a disposal bag reported proper opioid disposal (difference in proportions, 15.5%; 95% CI, 1.7%-29.3%; P = .03). Among only those families who filled an opioid prescription and had leftover opioids after resolution of their child's pain, 66 of 77 parents or guardians (85.7%) who had received a disposal bag and 50 of 77 parents or guardians (64.9%) who had received standard care reported properly disposing of their child's opioids (difference in proportions, 20.8%; 95% CI, 7.6%-34.0%). CONCLUSIONS AND RELEVANCE: Results of this study indicated that providing drug disposal bags to families of children receiving postoperative opioids increased the likelihood of excess opioid disposal. Greater availability of disposal products may complement ongoing prescribing reduction efforts aimed at decreasing opioid misuse. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03575377.
RESUMO
OBJECTIVE: To characterize the utilization of delayed phase computed tomography (CT) imaging in blunt renal trauma and determine if the omission of delayed phase CT imaging affected clinical outcomes in children. MATERIALS AND METHODS: A prospectively collected trauma database was reviewed between 2006 and 2016 to identify patients aged ≤21 years with a diagnosis of renal injury from blunt trauma. Demographic characteristics, injury grade, Injury Severity Score, non-kidney organ injuries, radiologic studies, and clinical course were reviewed. Patients were categorized into 2 groups: those who received CT with delayed images in the emergency room and those who did not. RESULTS: In total, 121 patients met the inclusion criteria. Delayed scans were obtained in 50 patients (41%) but omitted in 71 (59%). Age, weight, non-kidney organ injuries, and imaging location did not differ between groups. Injury Severity Score was higher in the no-delay group than in the delay group (median 16 vs 10, respectively, P = .40). Median length of stay was 3 days without significant differences by cohort (P = .24). The proportion of patients who received abdominal CT scans after admission, underwent a urologic procedure, or were readmitted did not differ significantly between groups. CONCLUSION: This study was unable to demonstrate a difference in outcomes between patients who had a CT with delayed imaging and patients who did not. This questions the universal necessity for delayed images after blunt renal trauma. Future prospective studies are necessary to develop pediatric trauma guidelines that balance imaging needs and radiation exposure.
