OBJECTIVE To determine the safety and efficacy of same-day urethral catheter removal after laser vaporization of the prostate and to identify factors contributing to a successful trial of void (TOV). METHODS We conducted a retrospective analysis of 98 patients who underwent laser vaporization of the prostate using GreenLightTM or Holmium XpeedaTM laser fibers from April 2018 to March 2021. All patients included in the study were offered a same-day TOV and had their catheters removed 3 hours postoperatively. Patient demographics, intraoperative parameters, and postoperative outcomes were collected and analyzed. Patients who were medically unfit or those on antiplatelet or anticoagulant medications were excluded. Multivariate logistic regression analyses were used to determine potential predictors of a failed TOV. RESULTS The median age of included patients was 69 years (56-86) with a prostate size of 54 grams (40-78.4). The median operative time was 50 min (20-93). Seventy-two patients (73.5%) had a successful TOV without the need for urethral catheter reinsertion. The median hospital stay for patients was 5 hours. Preoperative post-void residual (PVR) urine was the only predictor of a successful TOV on both univariate and multivariate logistic regression analyses. CONCLUSION Same-day catheter removal following laser vaporization of the prostate is a feasible option with a 73.5% success rate.
