Abstract

INTRODUCTION & OBJECTIVE: The opioid crisis has raised concerns for long-term sequela of routine administration of opioids to patients, particularly in the pediatric population. Nonsteroidal anti-inflammatory drug use is limited in hypospadias surgery due to concerns for post-operative bleeding, particularly with ketorolac. We hypothesize that ketorolac administration at the time of hypospadias repair is not associated with increased bleeding or immediate adverse events.

METHODS: A retrospective single institution study included all patients undergoing hypospadias surgery from 2018 to 2021. Outcomes measured include peri-operative ketorolac administration, opioid prescriptions, and unplanned encounters (i.e., emergency department or office visits). Comparative statistics using non-parametric and binary/categorical tests and a logistic regression were performed.

RESULTS: 1044 patients were included, among whom there were 562 distal, 278 proximal and 204 hypospadias complication repairs. Ketorolac was administered to 396 (37.9%) patients and its utilization increased during the study period [Summary Figure]. Patients receiving ketorolac were older (p = 0.002) and were prescribed opioids less often after surgery (2.0% vs 5.2%, p = 0.009). There was no difference in unplanned encounters across repair types (p = 0.1). Multivariate logistic regression showed ketorolac use was not associated with an increased likelihood of an unplanned encounter.

DISCUSSION: The use of NSAIDs post-operatively has traditionally been limited due to concerns about bleeding risks, however the present study displayed no significant increases in unplanned patient encounters either in the ED or outpatient clinic after ketorolac administration. Our study has several limitations including its retrospective and single-institutional design, difficulties of pain assessment in pediatric population, and possibility of under estimation of unplanned encounters due to limited access to patients' records outside of our institution.

CONCLUSIONS: The use of ketorolac is not associated with an increase in unplanned encounters in children undergoing hypospadias repair. It should be considered a safe agent for perioperative analgesia to decrease opioid utilization. Further studies will evaluate long-term surgical outcomes in children receiving ketorolac after hypospadias repair.

Abstract

INTRODUCTION: With the advent of robot-assisted laparoscopic ureteral reimplantation (RALUR) for primary vesicoureteral reflux (VUR), understanding and minimizing its complications continues to be critical. Incidence of de novo hydronephrosis after RALUR could be indicative of an outcome that needs further study or could be a benign transient finding.

OBJECTIVE: In the present study, we hypothesized that the incidence of de novo hydronephrosis after RALUR is low and resolves spontaneously.

METHODS: An IRB-approved prospective single-institutional registry was utilized to identify all patients undergoing RALUR via an extravesical approach from 2012 to 2020. Patients with primary VUR and minimal (Grade I SFU) or no hydronephrosis prior to surgery were included. Patients who had other associated pathology or underwent concomitant procedures were excluded. Preoperative characteristics including VUR and hydronephrosis grades as well as post-operative clinical details and hydronephrosis grades were aggregated and analyzed.

RESULTS: 86/172 (50%) patients (133 ureters), with median reflux grade of 3 (IQR: G2, G3) met the inclusion criteria. Patients underwent RALUR at a median age of 5.7 years (IQR: 3.4, 8.7) with median 36.2 months (IQR: 19.6, 63.6) follow-up. Renal ultrasound at 4-6 weeks post-op showed de novo hydronephrosis in 18 (13.5%) ureters; the complete resolution was seen in 13 ureters (72%) at a median of 4.5 months from surgery. Among the 5 with non-resolved hydronephrosis (SFU G2:4, G3:1), 2 patients (3 ureters) underwent subsequent interventions.

DISCUSSION: The present study evaluating the natural history of de novo hydronephrosis after RALUR-EV performed for primary VUR, is to our knowledge the largest cohort of patients undergoing RALUR that this has been studied in. In our cohort, the incidence of de novo hydronephrosis after RALUR was 13.5%, similar to rates reported in two OUR cohorts, and significantly lower than reported incidence rates of 22-26% in several OUR cohorts, and 30% in a RALUR cohort. In the present cohort, hydronephrosis resolved spontaneously in more than 72% of cases. The median time from surgery until resolution of hydronephrosis was 4.5 (1.6, 10.5) months, which is shorter in comparison to the average time to resolution of 7.6 months, reported by Kim et al. in an earlier study.

CONCLUSIONS: De novo hydronephrosis after RALUR can be followed with serial renal ultrasounds. The majority of de novo hydronephrosis post-RALUR is transient and resolves spontaneously within a year of surgery with a very low re-intervention rate.
