Introduction: Whereas the excellent functional outcomes after Holmium laser enucleation of the prostate (HoLEP) and its equivalency to open prostatectomy (OP) have been studied in detail in the past years, the oncological equivalency has yet to be investigated. Therefore, we conducted a matched pair analysis to evaluate and compare incidental prostate cancer detection rates after HoLEP and OP. Patients and methods: Preoperative patient age, total prostate-specific antigen (PSA), and prostate volume were used as primary matching criteria. Descriptive statistics were used to confirm matching quality. Statistical analyses were performed using Fisher ' s exact test and T-test or Mann-Whitney U-test for dichotomous and continuous variables, respectively. Results: After the matching procedure, 72 out of 145 patients after HoLEP and 72 out of 477 patients after OP were included. Mean patient age (70 vs. 71 years), median prostate volume (106 vs. 107 mL), and median preoperative total PSA (4.32 vs. 4.36 ng/mL) were almost identical. The amount of removed tissue did not differ between HoLEP and OP. Incidental prostate cancer detection rate was similar with 9.7% after HoLEP and 8.3% after OP (p = 1.000). Conclusion: This first matched pair analysis shows that HoLEP does not have a disadvantage regarding cancer detection rate during desobstructive surgery for large prostates. (C) 2018 S.
