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.

CONCLUSION

Early recovery of SUI within 1 month following HoLEP was associated with transition zone prostate volume and the enucleation ratio.
