Factors Predicting Successful Same-Day Trial of Void (TOV) After Laser Vaporization of the Prostate.

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 GreenLight or Holmium Xpeeda 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 minute (20-93). 72 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.

'Top-Down' holmium laser enucleation of the prostate. Report of initial cases performed by a single surgeon.

OBJECTIVES: To present the 12-month outcomes of 'Top-Down' holmium laser enucleation of the prostate (HoLEP). PATIENTS AND METHODS: We retrospectively reviewed the charts of prospectively collected patients who underwent Top-Down HoLEP between 2017 and 2018. All cases were operated upon by a single urologist (H.E), using a 100-W holmium:YAG laser with a 550-µm laser fibre. We recorded the enucleation time, morcellation time, intraoperative, and postoperative complications. All patients had postoperative follow-up visits at 1, 3, 6 and 12 months. The evaluation included the International Prostate Symptom Score (IPSS), quality-of-life (QoL) assessment, measurement of maximum urinary flow rate (Qmax) and the post-void residual urine volume (PVR). RESULTS: A total of 60 consecutive patients were recruited. The median (range) prostatic volume, resected prostatic weight, and percentage of resected prostatic tissue were 124 (70-266) mL, 90 (44-242) g and 76 (46-97)%, respectively. The median (range) enucleation and morcellation times were 80 (25-200) and 14.5 (4-58) min, respectively. One patient had a simple bladder mucosal injury and another developed clot retention. At 3 months, three patients (5%) had stress urinary incontinence (SUI) and eight patients (13.3%) presented with urge UI (UUI). At the last follow-up visit, one patient (1.7%) presented with persistent SUI, while three patients (5%) presented with UUI. The IPSS and QoL significantly improved during the follow-up period (P = 0.045 and P = 0.04, respectively). CONCLUSION: The results of the Top-Down technique are comparable to those of traditional HoLEP. However, the Top-Down technique may reduce the complexity, operating time, and SUI rates. ABBREVIATIONS: BN: bladder neck; HoLEP: holmium laser enucleation of the prostate; PVR: post-void residual urine volume; Qmax: maximum urinary flow rate; QoL: quality of life; TOV: trial of voiding; (S)(U)UI: (stress) (urge) urinary incontinence.
