Predictors of Failed Same-Day Catheter Removal After Holmium Laser Enucleation of the Prostate

Abstract

ObjectiveTo determine factors associated with failure of same-day trial of void (SDTOV) following holmium laser enucleation of the prostate (HoLEP). BackgroundHoLEP is increasingly utilized for patients with benign prostatic hyperplasia. Advancements in technology have improved operative efficiency and hemostasis making same-day, catheter-free discharge possible. MethodsWe conducted a retrospective review on 190 patients undergoing HoLEP from July, 2021 to January, 2022 by a single center. We assessed pre- and intra-operative variables associated with our primary outcome: failure of same-day catheter removal. Post-operative complications and outcomes at a ≤7 days and 3-month follow up were examined. Continuous and categorical variables were analyzed using unpaired t-tests (Mann Whitney) and chi-square, respectively. Univariate and multivariable logistic regression models were fitted to examine the associations of failed SDTOV. ResultsOf 190 candidates for a SDTOV, 90% (171/190) were successful. We found no difference between SDTOV success and failures with regards to age, comorbidities, presence of pre-operative urinary retention, anesthesia factors, operative time, volume resected, enucleation time, and morcellation time (all P>0.05). Pre-operatively, 26.3% (50/190) were on antiplatelet and 6.3% (12/190) were on anticoagulation. While pre-operative antiplatelet therapy was not associated with SDTOV failure (P=0.78), pre-operative anticoagulation use was (4.7% vs. 21.1%, P=0.021). Patients who continued anticoagulation through surgery had the highest rate of SDTOV failure (2.3% (4/171) vs. 15.8% (3/19), P=0.023). For those with successful SDTOV, 4.1% (7/171) required catheterization following discharge. At 3 months, no patient required catheterization. ConclusionOn the day of surgery, patients eligible for SDTOV successfully voided 90% of the time. History of preop anticoagulation, whether continued or held, increased SDTOV failure.
