Comparative study of HoLEP in elderly patients with indwelling catheters: a retrospective dual-center study.

Abstract

Introduction: This study aimed to evaluate the safety and efficacy of HoLEP in patients aged > 85 years with indwelling catheter (IDC).

Methods: We retrospectively analyzed our bicentric HoLEP database to identify consecutive patients with IDC and trial without catheter (TWOC) failure who underwent surgery between June 2012 and April 2020. Our primary focus was on the population over 85 years of age; Patients under 70 years of age were used as controls. We evaluated the rate of postoperative spontaneous micturition, adverse events and mortality, as well as catheterization duration, hospital stay, and rate of urinary incontinence.

Results: In total, 144 patients were included, with 71 (49.3%) and 73 (50.8%) in the ≥ 85 and control group, respectively. The median [IQR] prostatic volume and Charlson score was 90 [70-130] vs. 90 [65-120] mL and 6 [5-7] vs. 3 [2-4] in the ≥ 85 and control groups, respectively. Postoperatively, the rates of major complications (2% vs. 3%) and transfusion (11% vs. 9%) were not significantly different. The median length of stay (2 [1-3] vs. 1 [1-2]; p = 0.03) and rate of TWOC failure during hospitalization (24% vs. 5%, p < 0.001) were significantly higher in the ≥ 85 group. At 3 months and one year follow-up visits, 0 and 10 patients (14.1%) in the ≥ 85 group and 0 and 2 patients (3%) in the control group died, respectively. One year after surgery, 69 (97%) and 73 (100%) (p = 0.2) patients in the ≥ 85 and control groups, respectively, could void spontaneously.

Conclusion: HoLEP is a safe and effective procedure for elderly patients with indwelling catheters. At one year, 97% of patients achieved spontaneous voiding, while the urinary incontinence rate was 11%. The 1-year mortality rate was 14%, comparable to that of the general male population of the same age.
