%X Surgery for benign prostatic hyperplasia (BPH) has greatly advanced with the development of laser technology ; and holmium laser enucleation of the prostate (HoLEP), which can be performed safely and with minimal invasiveness regardless of prostate size. Incidental prostate carcinoma (iPCa) following HoLEP occurs at a certain rate. Predictors, include age, biopsy, history, preoperative prostate specific antigen, and prostate volume. We compared cases with and without incidental carcinoma detection among 257 patients with BPH who underwent HoLEP at our hospital from July 2015 to December 2022. Among the 257 patients, 29 (11.3%) were found to have incidental carcinoma. Although 1 patient switched to endocrine therapy the remaining patients showed good prognosis under surveillance therapy. The proportion of cases with magnetic resonance imaging (MRI) findings suggestive of carcinoma was significantly higher in the incidental carcinoma detection group (p＝0.009). Furthermore, univariate analysis of incidental carcinoma predictive factors revealed a significant difference in MRI findings (odds ratio [OR] 2.92 ; confidence interval [CI] 1.33-6.42), and multivariate analysis showed similar results (OR 2.92 ; CI 1.33-6.42). At our hospital, we currently perform MRI scans for preoperative morphological assessments but not for cancer diagnosis. However, based on the results obtained, we aim to proactively utilize MRI for preoperative malignant screening, in addition to PSA.
