研究室紹介
Professor Sang Hun Song's research lab specializes in urological oncology and minimally invasive surgical techniques, with a strong focus on improving outcomes in prostate and upper tract urothelial cancers. The lab investigates advanced imaging strategies—particularly MRI and PI-RADS—to optimize biopsy decision-making and enhance early detection of clinically significant prostate cancer. It also explores ethnic disparities in prostate cancer genetics, developing population-specific polygenic risk scores to improve risk prediction in Asian men. Additionally, the lab examines surgical learning curves and pharmacological optimization in benign prostatic hyperplasia, aiming to refine clinical decision-making and patient care.

6This study was performed to investigate the learning curve of transurethral enucleation with bipolar energy (TUEB) for benign prostatic hyperplasia. The study involved 494 consecutive patients who underwent TUEB for benign prostatic hyperplasia from August 2018 to March 2022 by one surgeon (SJJ, Seoul National University Bundang Hospital, Seongnam, Korea). The patients were followed up at 1 week, 1 month, 3 months, and 6 months postoperatively. To evaluate the learning curve of TUEB, perioperati
PI-RADS 3 lesions represent a diagnostic challenge in repeat prostate biopsy. We investigated whether PI-RADS 3 independently predicts negative biopsy outcomes and how PSA density (PSAD) modifies cancer detection across PI-RADS categories. We retrospectively analyzed 684 patients who underwent repeat MRI-guided prostate biopsy between 2015 and 2022. PI-RADS scores, clinicopathologic variables, biopsy Gleason Scores, and radical prostatectomy findings were assessed. Univariate and multivariate lo
RNU can be safely and effectively performed in well-selected OG with UTUC. Age ≥80 years was not associated with inferior CSS outcomes or increased major morbidity.
Prostate cancer exhibits marked ethnic differences in genetic architecture. Although polygenic risk scores (PRS) and germline genetic testing have shown clinical utility in European populations, their applicability to Asian populations remains limited. This review synthesizes evidence published between 2020 and 2025 on PRS and germline genetics in Asian prostate cancer cohorts, focusing on Chinese, Japanese, and Korean populations. Recent studies demonstrate that population-specific PRS models e
Escalating tamsulosin from 0.2 to 0.4 mg can meaningfully improve urinary flow in certain BPH patients, particularly those with larger prostates or concomitant 5-alpha-reductase inhibitor therapy.
Magnetic resonance imaging (MRI) has become an important tool for recommending prostate biopsy (PB) in prostate cancer (PCa) detection. However, the routine use of MRI in patients with previous negative PB remains debatable. This study aimed to evaluate the utility of prostate-specific antigen (PSA) derivatives to guide MRI use and reduce unnecessary scans in such cases. Receiver operating characteristic analysis identified a Prostate Imaging Reporting and Data System score ≥ 4 as the optimal th
