Caudal anesthesia is not associated with post-operative complications following distal hypospadias repair.

INTRODUCTION: The use of caudal anesthesia at the time of hypospadias repair remains controversial as some prior studies have reported increased postoperative complication rates associated with caudal nerve block. However, these results have been called into question due to confounding factors and heterogeneous study groups. OBJECTIVE: Given the importance of identifying true risk factors associated with increased hypospadias complication rate, we examined our experience with caudal anesthesia limiting our analysis to distal repairs. We hypothesized that caudal anesthesia would not be associated with increased postoperative complications. STUDY DESIGN: We retrospectively reviewed our institutional hypospadias database from June 2007 to January 2021. All boys who underwent single-stage distal hypospadias repair with either caudal or penile block with minimum 1 month follow up were included. Records were reviewed to determine the type of local anesthesia, type of hypospadias repair, all complications, and time to complication. Association between any complication and local anesthesia type was evaluated by univariate and multivariate logistic regression analysis controlling for age at surgery and type of repair. A sub-analysis was performed for complications occurring ≤30 days. RESULTS: Overall, 1008 boys, 832 (82.5%) who received caudal and 176 (17.5%) penile block, were included. Median age at surgery was 8.1 months and median follow up was 13 months. Overall complication rate was 16.4% with 13.8% of patients requiring repeat operation. Median time to complication was 10.59 months and was significantly shorter in the caudal group (8.45 vs. 25.2 months). Caudal anesthesia was associated with higher likelihood of complication on univariate analysis; however, this was not true on multivariate analysis when controlling for age and type of repair. Caudal anesthesia was not associated with increased likelihood of complication within 30 days. DISCUSSION: Since the association between caudal anesthesia and hypospadias complications was first suggested, several studies have tried to answer this question with variable results. Our findings add to the evidence that there is no association between caudal anesthesia and increased hypospadias complications in either the short or long term. The major strengths of our study are a large, homogenous study population, robust follow up and inclusion of data from 14 surgeons over 14 years. Limitations include the study's retrospective nature as well as lack of standardized follow up protocol throughout the study period. CONCLUSIONS: After controlling for possible confounders, caudal nerve block was not associated with increased risk of postoperative complications following distal hypospadias repair.

Trends in opioid and nonsteroidal anti-inflammatory (NSAID) usage in children undergoing common urinary tract reconstruction: A large, single-institutional analysis.

INTRODUCTION AND OBJECTIVE: Opioid stewardship is recognized as a critical clinical priority. We previously reported marked reductions in narcotic administration after implementation of an opioid reduction protocol for pediatric ambulatory urologic surgery. We hypothesize that a decrease in post-operative and discharge opioid administration will not increase short-term adverse events. STUDY DESIGN: All pediatric patients undergoing open or robot-assisted laparoscopic pyeloplasty or ureteral reimplantation between 2015 and 2019 were included. Patients' demographics, opioid and NSAID administration, urology or pain-related emergency department (ED) visits, readmissions, and reoperations within 30 days of surgery, were aggregated. RESULTS: 438 patients, with a median age of 3.5 years (IQR 1.5-8.3) at the time of surgery, met the inclusion criteria. Annual rates of inpatient opioid administration and prescriptions decreased significantly over the study period, while rates of intra-operative, inpatient, and prescribed NSAIDs significantly increased. There was no significant difference in the occurrence of ED visits, readmissions, or reoperations within 30 days of surgery between patients who received an opioid prescription and those who did not. Multivariate regression showed that patients who did not receive an opioid prescription at discharge were found to be at a lower risk for unplanned encounters including ED visits, readmissions, or reoperations (OR:0.5, 95%CI: 0.2-0.9, p = 0.04). DISCUSSION: The present study shows the decreasing trend in inpatient opioid administration and opioid prescription after discharge, when accompanied by an increase NSAID administration, does not result in a significant change in rates of unplanned encounters and complications, similar to results from previous studies on non-urological and ambulatory urological surgeries. CONCLUSIONS: Non-opioid pain control after major pediatric urologic reconstruction is safe and effective. We found that a reduction in opioid administration can be associated with a reduced risk of unplanned ED visits, readmissions, or reoperations. Further investigations are required to corroborate this finding.

Quantifying Glans Width Changes in Response to Preoperative Androgen Stimulation in Patients Undergoing Hypospadias Repair.

PURPOSE: Testosterone (T) administration prior to hypospadias surgery to increase glans size remains controversial. Understanding T's effect on glans width (GW) is essential to understanding its potential impact on surgical outcomes. We hypothesized that preoperative T in prepubertal boys significantly increases GW at the time of hypospadias surgery. MATERIALS AND METHODS: Our single institutional database was queried to identify patients who underwent hypospadias surgery from 2016 to 2020, in which data for T administration and GW were available. Descriptive, nonparametric and categorical statistics were performed as indicated. RESULTS: A total of 579 patients were eligible for analysis. Median age at surgery was 0.9 years (IQR 0.6-1.6). A total of 247/579 patients (42.7%) received T. The median GW at surgery was 15 mm (IQR 13-17). When comparing patients who had T administered to those who did not, we found a significant difference in GW at surgery (16 mm vs 14 mm, p <0.001). The median change in GW from the office to surgery was 4 mm for those receiving T vs 0 mm for those not receiving T (p <0.001). We identified a greater change in GW from preoperative to intraoperative measurements in patients who received 2 doses of T vs 1 dose (4 mm vs 2 mm, p <0.001). A histogram plot revealed the distribution of GW change at surgery. CONCLUSIONS: In our prospectively collected cohort of patients undergoing hypospadias surgery, we were able to quantitate the change in GW from preoperative T. Two doses of T resulted in a significant increase in GW vs 1 dose.

Family economic stress and academic well-being among Chinese-American youth: the influence of adolescents' perceptions of economic strain.

This study examined the pathways by which family economic stress influenced youth's educational outcomes in a sample of 444 Chinese American adolescents (M ages = 13.0, 17.1 years at waves 1 and 2, respectively). Using latent variable structural equation modeling, results across two waves of data, spanning early to late adolescence, demonstrated that the influence of parent report of economic stress on youth academic achievement (i.e., GPA), school engagement, and positive attitudes about education was mediated through youth's perceptions of family economic strain and self-reports of depressive symptoms. These relationships were observed to remain significant after accounting for selection bias using individual fixed-effects models. Finally, youth's perceptions of family economic strain were found to more strongly predict depressive symptoms during later, as compared to earlier, adolescence; all other modeled relationships were equivalent across the two time periods. Implications for expanding theoretical tenets of the Family Economic Stress Model are discussed.
