Short-Term Clinical Outcomes of Bladder Neck Incision at Time of Holmium Laser Enucleation of the Prostate

Abstract

Introduction:

The effect of prophylactic bladder neck incision (BNI) at time of holmium laser enucleation of the prostate (HoLEP) is unknown. The aim of our study was to examine HoLEP outcomes with a specific focus on rates of bladder neck contractures (BNCs), with and without utilizing prophylactic BNI.

Materials and Methods:

We performed a retrospective review of HoLEP patients from January 2021 until January 2022. Outcomes of patients who underwent BNI at time of HoLEP were compared with those who underwent standard HoLEP alone. Student's t-tests, chi-square tests, and logistic regressions were performed using SAS Studio.

Results:

In total, 421 patients underwent HoLEP. BNI was concurrently performed in 74 (17.6%) HoLEP patients. BNI patients were younger (67.5 ± 9.0 years vs 71.1 ± 8.2 years, p = 0.00007) and had smaller prostates (60.7 ± 30.3 cc vs 133.2 ± 64.5 cc, p < 0.0001). Procedure, enucleation, and morcellation times were shorter in the BNI group (all p < 0.0001). There was no statistical difference in same-day discharge rates (90.4% vs 87.7%, p = 0.5), short-term functional outcomes, emergency department (ED) visits, or readmission rates between the two groups. At 14 months mean follow-up, two BNCs occurred in patients in the control group (0.6%), and no BNCs occurred in patients who underwent BNI (0.0%, p = 0.5).

Conclusions:

BNI at time of HoLEP did not decrease the ability to achieve same-day discharge or increase 90-day complications, ED visits, or readmission rates. No BNCs occurred in patients who underwent prophylactic BNI (0.0%) despite a smaller gland size and lower specimen weight in this cohort. Further prospective studies are required to conclude if concurrent BNI at time of HoLEP is protective against BNC.
