Robotic Versus Open Ureteroneocystostomy: Is There a Robotic Benefit?

We sought to compare the outcomes of patients who underwent an open vs robotic ureteroneocystostomy for ureteral obstruction. Retrospective review was performed on adult patients who underwent primary ureteroneocystostomy for obstruction from January 2012 to April 2018. Intraoperative outcomes of estimated blood loss (EBL) and operative time, as well as postoperative outcomes of catheter and stent duration, length of hospital stay, inpatient nurse-controlled opioid use, patient-controlled analgesia (PCA), and outpatient opioid prescription, complications, readmission, radiologic and clinical stricture recurrence, and follow-up, were compared. Among the open cohort, indications for an open approach were evaluated, identifying patients with prior complex open abdominal surgery that would make an open approach preferable. Open ureteroneocystostomy was performed in 27 patients compared with 18 who underwent a robotic approach. The open and robotic cohorts were not significantly different in age, gender, Charlson comorbidity index, stricture location or side, abdominal surgery (laparoscopic or open), pelvic radiation, or preoperative urinary tract infection. The robotic group had a significantly lower rate of prior open abdominal surgery. The robotic cohort had significantly lower EBL, length of stay (LOS), catheter duration, prescribed morphine milliequivalents (MME) at discharge, and rate of PCA usage. Among the open cohort, 13 (48%) patients demonstrated indications making an open approach preferable. Comparing the robotic group with the remaining 14 open patients revealed a significantly lower rate of inpatient PCA use, prescribed MME at discharge, LOS, and catheter duration. Mean operative time was higher in the robotic group. EBL was not significantly different in this subanalysis. Robotic ureteroneocystostomy provides similar outcomes when compared with an open approach in well-selected patients when assessing for recurrent ureteral obstruction or adverse events. Robotic surgery is associated with lower postoperative narcotic pain prescriptions at discharge, lower PCA usage, and shorter LOS, which are important benefits when compared with open surgery.
