Factors associated with early recovery of stress urinary incontinence following holmium laser enucleation of the prostate in patients with benign prostatic enlargement

Purpose: To investigate factors associated with early recovery of stress urinary incontinence (SUI) following holmium laser enucleation of the prostate (HoLEP) in patients with benign prostatic enlargement (BPE). Methods: The medical records of 393 patients who underwent HoLEP for BPE were retrospectively reviewed. Patients with SUI following HoLEP were selected and divided into 2 groups: Those who experienced early recovery of SUI and those who experienced persistent SUI. Recovery of SUI within 1 month after HoLEP was defined as early, and SUI that remained present after 1 month was defined as persistent. Preoperative clinical and urodynamic factors, as well as perioperative factors, were compared between groups. Results: SUI following HoLEP was detected in 86 patients. Thirty-three patients exhibited recovery of SUI within 1 month, and SUI remained present in 53 patients after 1 month. Multivariate analysis showed that the transition zone prostate volume (odds ratio [OR], 5.354; 95% confidence interval [CI], 1.911-14.999; P=0.001) and the enucleation ratio (OR, 8.253; 95% CI, 1.786-38.126; P=0.007) were significantly associated with early recovery of SUI. Conclusions: Early recovery of SUI within 1 month following HoLEP was associated with transition zone prostate volume and the enucleation ratio.
