{Abstract}: <B>OBJECTIVE: </B>Despite advancements in prostate multiparametric magnetic resonance imaging (mpMRI) and fusion biopsy (FB), the management of incidental prostate cancer (IPCa) after surgery for benign prostatic obstruction (BPO) remains unclear. The aim of this retrospective study is to determine the prevalence of IPCa in our cohort and identify potential predictors for its occurrence.<BR><B>METHODS: </B>We enrolled patients underwent TURP or simple prostatectomy for BPO at our high-volume center between January 2020-December 2022. Data on age, pre-operative total PSA (tPSA) and PSA density (PSAd) levels, prostate volume, previous MRI, biopsies, specimen weight, rates of positive tissue slices, ISUP score and three-month tPSA were collected.<BR><B>RESULTS: </B>Of 454 patients with negative digital rectal examination who underwent BPO surgery, 74 patients (16.3%) were found to have IPCa. Of these, 33 patients (44.6%) had undergone previous mpMRI. Among the patients who had mpMRI, 23 had negative mpMRI results for suspected prostate cancer, while 10 had positive mpMRI findings (PIRADS ≥ 3) but no evidence of tumor upon FB. KW analysis indicates that PSAd was statistically associated with higher ISUP score, while at univariable regression analysis negative mpMRI (p = 0.03) was the only potential predictor for IPCa.<BR><B>CONCLUSIONS: </B>Among the ISUP groups, PSAd showed a correlation with the tumor, while negative mpMRI was protective against clinically significant PCa. In the era of mpMRI and FB, the IPCa rates found at our center is higher than reported in existing literature and if it were confirmed with further studies, maybe there is a need for expansion in urology guidelines.
