OBJECTIVE: To evaluate the safety and efficacy of routine ambulatory percutaneous nephrolithotomy (PCNL) in a freestanding ambulatory surgical center.
METHODS: Patients were treated between 2015 and 2022 by one of three experienced endourologists in Maryland. The surgery center is free-standing, with the nearest hospital approximately 10 minutes away. Patient characteristics and surgical datapoints, including need for transfer, were gathered prospectively at the time of surgery. Subset analyses were performed in patients with staghorn calculi or elevated body mass index, as they represent higher-risk populations.
RESULTS: A total of 1267 patients underwent ambulatory PCNL with a median stone diameter of 32 mm. The average recovery time was 87 minutes, with 1.7% of patients requiring transfer to the hospital, generally for postoperative hypotension or inadequate pain control. 166 patients with body mass index >40 were safely treated, with no significant difference in transfer rate (P = .5). 2.8% of patients had a complication, with the majority being Clavien-Dindo grade I or II. 88 patients with staghorn calculi were treated, with a 6% transfer rate. Staghorn calculi were the only factor found on multivariable analysis to be a significant predictor of transfer (OR 3.56 (1.17-10.82) P < .05).
CONCLUSION: Ambulatory PCNL may safely be performed in a surgery center in most patients. These outcomes reflect the real-world experience of high-volume surgeons and demonstrate a multiyear paradigm shift in PCNL from an inpatient procedure to an outpatient procedure in a surgery center.
