Prior to nephrectomy, six patients were on hemodialysis, two patients were on peritoneal dialysis (PD), and two patients were not on any form of dialysis. Of the 10 patients, four underwent surgery during an inpatient admission for an acute exacerbation of the listed indication. Three cases were done robotically (transperitoneal), and seven were performed open. Both patients on PD preoperatively underwent open retroperitoneal surgery and were able to restart PD on postoperative day 1. There was one complication in a patient with recurrent UTIs who developed an intra-abdominal abscess, requiring percutaneous drainage.</p><p><strong>Conclusions: </strong>Bilateral simultaneous native nephrectomy is a safe and effective way to manage conditions associated with end-stage renal disease in pediatric patients.
