Comparison of Postoperative Outcomes of Trans-urethral Resection of the Prostate, Laser Vaporization, and Laser Enucleation: A Double Propensity Score Matched Analysis

Abstract

To compare postoperative outcomes of three types of endourologic surgeries (TURP, laser vaporization (LVP) and laser enucleation (LEP)) for BPH treatment using the ACS-NSQIP database. The ACS-NSQIP database was queried for men who underwent TURP, PVP and LEP for treatment of BPH from 2011 till 2019. Demographics, clinical, operative characteristics, and 30-day outcomes were compared. Univariate and multivariate regression models were constructed. Propensity score matching was then performed as a sensitivity analysis. 74,273 patients underwent endourologic surgeries for BPH, 65.4% had TURP, 28.6% PVP, and 5.9% LEP. Patients undergoing TURP were more likely to be older with higher ASA class, abnormal labs, and comorbidities (diabetic, congestive heart failure, and bleeding requiring transfusion) (p-value<0.001). After adjusting for covariates and propensity score matching, LVP demonstrated shorter hospital stays, shorter operative times, less reoperation rates, decreased DVT/PE risk, with however higher odds of urinary tract infection and sepsis as compared to TURP (p-value <0.028). Furthermore, LEP was found to have shorter hospital stays, longer operative times, and decreased odds of urinary tract infections and sepsis as compared to TURP (p-value <0.006). LVP and LEP showed better surgical outcomes and characteristics as compared to TURP. Further research is needed to account for longer duration of follow-up and patient-specific urologic outcomes, such as prostate size, urinary incontinence, erectile dysfunction, and retrograde ejaculation.
