Comprehensive review of a large cohort of outpatient versus inpatient open renal and bladder surgery in children.

INTRODUCTION

Outpatient surgery and pediatric ambulatory surgery centers continue to have increasing popularity among pediatric urologist for minor surgeries. Past studies have shown that open renal and bladder surgeries (i.e. nephrectomy, pyeloplasty and ureteral reimplantation) can also be done in an outpatient setting. With health care costs continuing to rise, it may be reasonable to explore performing these surgeries as an outpatient and consider performing them in a pediatric ambulatory surgery center.

OBJECTIVE

Our study assesses the safety and utility of outpatient open renal and bladder surgeries in children compared to those done as inpatients.

STUDY DESIGN

IRB-approved chart review was performed on patients undergoing nephrectomy, ureteral reimplantation, complex ureteral reimplantation, and pyeloplasty by a single pediatric urologist between January 2003-March 2020. Procedures were performed at a freestanding pediatric surgery center (PSC) and a children's hospital (CH). Demographics, type of procedures, American Society of Anesthesiologists score, operative times, time to discharge, ancillary procedures, readmission or ER visits within 72 h were reviewed. Home zip codes were used to determine the distance from pediatric surgery center and children's hospital.

RESULTS

980 procedures were evaluated. Of these, 94% procedures were performed as an outpatient and 6% procedures were performed as inpatients. 40% of patients underwent ancillary procedures. Outpatients had a significantly lower age, ASA score, operative time, and readmission or return to ER within 72 h (1.5% vs. 6.2%). Twelve patients were readmitted (9 outpatient, 3 inpatient) and six returned to the ER (5 outpatient, 1 inpatient). 15/18 of these patients underwent reimplantations. Four required early reoperation on postoperative day (POD)2-3. Only one outpatient reimplant was admitted one day later. PSC patients lived farther away.

DISCUSSION

Outpatient open renal and bladder surgery was found to be safely performed in our patients. In addition, it did not matter whether the operation was done in the children's hospital or pediatric ambulatory surgery center. Since outpatient surgery has been shown to be significantly less expensive than inpatient surgery, it is reasonable for pediatric urologist to consider performing these operations in the outpatient setting.

CONCLUSIONS

Our experience shows that an outpatient approach to open renal and bladder procedures is safe and should be considered when counseling families about treatment options.
