Predictive factors of post-HoLEP incontinence: differences between stress and urgency urinary incontinence

Abstract

Introduction: The analysis of post-HoLEP urinary incontinence (UI) has traditionally focused on stress UI. Our aim is to evaluate the factors associated with stress and urgency UI in the first month after the surgery.

Methods: Data were obtained from patients who underwent HoLEP by the same experienced surgeon. UI was evaluated at one month and at 6 months after the surgery. Three groups were defined: continent patients, patients with pure urgency UI and patients with stress or mixed UI. Preoperative, intraoperative, urodynamic and clinical variables were analyzed and compared between the three groups.

Results: In total, 235 subjects were included. One month after the surgery, 156 (66.5%) were continent (group 1), 49 (20.8%) reported pure urgency UI (group 2), and 30 (12.7%) reported some level of stress UI (group 3). In Group 2, the factors associated with urgency UI in the univariate analysis were age, presurgical urgency UI, having diabetes or hypertension. In Group 3, age, prostatic volume, preoperative PSA, time of enucleation, weight of the resection in grams, having an IDC or being diabetic were significant in the univariate analysis. In the multivariate analysis, age predicts both types of UI, while prostatic volume and having an IDC predict stress or mixed UI.

Conclusion: In the first month post-HoLEP, age is a predictive factor of urgency UI and stress UI. In addition, prostatic volume and the presence of an indwelling urinary catheter are predictive factors of stress UI.
