Tubeless outpatient robotic upper urinary tract reconstruction in the pediatric population: short-term assessment of safety.

Robotic upper urinary tract reconstruction (UUTR) has been widely utilized for surgical management of congenital obstruction. To further reduce morbidity and simplify postoperative care, outpatient robotic pyeloplasty (RP) and robotic ureteroureterostomy (RUU) were performed without ureteral stents, drains, or urethral catheters. The aim of the study was to assess the safety of performing tubeless robotic UUTR as an outpatient procedure. A retrospective review was performed for patients who underwent outpatient tubeless RP and RUU between July 2015 and January 2017. All procedures were primary interventions. No ureteral stents, drains, or urethral catheters were utilized. No regional blocks were utilized. Patients were discharged from the post anesthesia care unit as a scheduled outpatient procedure without an extended stay. Primary outcomes included 30-day complications, emergency room (ER) visits, and readmissions. A total of 19 patients (14 male, 5 female) were identified (RP = 17, RUU = 3), including one patient who underwent staged bilateral RP. Median age was 21.5 months (range 3-220). Median weight was 11.5 kg (range 6-89). Median operative time was 167 min (range 108-249), defined as skin incision to closure. No 30-day complications, ER visits, or readmissions were observed for any patient. The study concludes that pediatric tubeless outpatient robotic UUTR is safe. Further evaluation is needed to assess this approach on a larger scale, as well as assessing the long-term outcomes of tubeless reconstruction.
