Single-port Mini-Pfannenstiel Robotic Pyeloplasty: Establishing a Non-narcotic Pathway Along With a Same-day Discharge Protocol

Objective: To analyze the feasibility of a same day discharge protocol following single-port (SP) robotic pyeloplasty. Materials and Methods: From a single institution series, 23 patients (12 multi-port, 11 SP) who underwent primary robotic dismembered pyeloplasty between February 2018 and March 2021 were analyzed. The association between baseline and perioperative characteristics with functional outcome was analyzed using, chi-square, Fisher's exact, Mann Whitney U and t tests. Results: All SP cases were completed using the mini Pfannenstiel incision without the need for conversion or additional ports. Baseline characteristics were comparable. No intraoperative complications were seen. Only 1 patient in the SP group had a Clavien II complication. All patients in the multi-port group had a drain placed, whereas drain was not placed in the SP group. Length of stay was shorter in the SP group (11.4 vs 42.6 hours, P <.001). Although visual analog pain score was comparable at discharge (P = .633), the SP group had lower opioid usage (morphine milligram equivalent) in the hospital (P <.001) and a lower rate of opioid prescription during discharge (18.2% vs 91.7% P <.001). At a median follow-up of 8 months, no patients had flank pain and all patients had good kidney drainage on follow-up images. Conclusion: Single-port robotic dismembered pyeloplasty through a mini-Pfannenstiel access allows a same-day discharge protocol with minimal opiate use.
