Predictors of Prolonged Time to Ambulation After Radical Prostatectomy in a 23-hour Ambulatory Surgery Center.

Purpose: The purpose of this study was to identify factors associated with delayed ambulation in patients undergoing radical prostatectomy in an ambulatory surgery setting. Materials and Methods: Patients who underwent ambulatory robot-assisted radical prostatectomy between January 11, 2016, and December 27, 2022, were eligible for inclusion. Predictors of interest included age, body mass index (BMI), American Society of Anesthesiologists physical status (1/2 vs 3/4), operative time, volume of intravenous fluids, estimated blood loss, intraoperative oral morphine equivalents, and postoperative nausea and vomiting (PONV) risk using 4-point Apfel scoring. Results: = .006). Conclusions: Our study identified an association between preoperative PONV risk score and delayed ambulation. Although high PONV risk is more commonly observed in women, our findings suggest that awareness of PONV risk and its management on postoperative ambulation should also be investigated in the context of prostate surgery.
