An Outcomes Comparison Between Holmium Laser Enucleation of the Prostate, Open Simple Prostatectomy, and Robotic Simple Prostatectomy for Large Gland Benign Prostatic Hypertrophy.

To compare perioperative outcomes between Holmium laser enucleation of the prostate (HoLEP), open simple prostatectomy (OSP), and robotic simple prostatectomy (RSP) for large prostates (> 80 cc). A retrospective study of 340 patients who underwent HoLEP (n = 209), OSP (n = 66), or RSP (n = 65) at a large academic medical center between January 2013 - September 2021 was performed. Length of stay (LOS), operative time, catheter duration, estimated blood loss (EBL), blood transfusion, and 30-day ED visits and readmissions were compared between the three groups. Univariate analyses consisted of ANOVA with Tukey's corrections and Chi-square tests. Linear and multivariate logistic regression was also performed. All tests were two-sided and a p-value <0.05 was pre-determined to be statistically significant. Analyses were performed with SAS v9.4. HoLEP was found to have the shortest: operative time (1.4 vs 2.7 vs 3.8h), LOS (0.65 vs 4.2 vs 2.6d), and catheter duration (0.38 vs 9.9 vs 11.2d) compared to OSP and RSP, respectively (all P <.0001). HoLEP also had the lowest EBL (66 vs 795 vs 326 mL, P <.0001). HoLEP and RSP had a lower risk of blood transfusion compared to OSP (P <.0001). These associations remained significant on multivariable analyses. HoLEP is a minimally invasive treatment option for large prostates that was found to have shorter operative time, LOS, and catheter duration as well as lower EBL compared to OSP and RSP.
