INTRODUCTION We compared the pathologic outcomes of prostate cancer patients who did not qualify for active surveillance according to the tumor visibility on multiparametric magnetic resonance imaging. MATERIAL AND METHODS We retrospectively analyzed 464 prostate cancer patients who underwent multiparametric magnetic resonance imaging before radical(More)
OBJECTIVES To compare the oncological outcomes of robot-assisted laparoscopic radical prostatectomy with those of open radical prostatectomy in contemporary Korean prostate cancer patients. METHODS From a group of 1172 patients consisting of 592 (50.5%) robot-assisted laparoscopic radical prostatectomy and 580 (49.5%) open radical prostatectomy cases(More)
BACKGROUND Trifecta achievement in partial nephrectomy (PN) is defined as the combination of warm ischemia time ≤ 20 min, negative surgical margins, and no surgical complications. OBJECTIVE To compare trifecta achievement between robotic, laparoendoscopic, single-site (R-LESS) PN and multiport robotic PN (RPN). DESIGN, SETTING, AND PARTICIPANTS Data(More)
OBJECTIVE To evaluate the effect of the prostatic urethral angle (PUA) on the peak flow rate (Qmax) and urinary symptoms in the clinical setting. MATERIALS AND METHODS The records were obtained from a prospectively maintained database for first-visit men with lower urinary tract symptoms. Uroflowmetric measurements, postvoid residual urine volume, and(More)
The purpose of this study was to determine the impact of obesity on clinicopathological features and biochemical recurrence (BCR) following radical prostatectomy (RP) in Korean prostate cancer (PCa) patients. A single-institutional retrospective analysis was performed on 880 PCa patients treated by RP without neoadjuvant therapy between July 2005 and(More)
PURPOSE The purpose of this study is to set guidelines for the management of renal angiomyolipoma (AML), clinical prognosis according to tumor size, in association with tuberous sclerosis complex (TSC), multiplicity, radiographic finding, and treatment modality. MATERIALS AND METHODS Between March 1998 and October 2008, 129 out of 254 patients with AML(More)
In line with the era of targeted therapy (TT), an increasing number of prognosticators are becoming available for patients with metastatic renal cell carcinoma (mRCC). Here, potential prognosticators of cancer-specific survival (CSS) were identified based on the contemporary literature and were comprehensively validated in an independent cohort of patients(More)
OBJECTIVES To examine the efficacy of octreotide for management of lymphorrhea after pelvic lymph node dissection (PLND) in radical prostatectomy. Lymphorrhea refers to the drainage of lymphatic fluid that occurs because of surgical dissection and inadequate closure of afferent lymphatic vessels. METHODS We enrolled 89 patients from whom more than 200 mL(More)
PURPOSE We analyzed the pathological outcomes of candidates for active surveillance according to tumor lesion diameter on diffusion weighted magnetic resonance imaging. MATERIALS AND METHODS We retrospectively analyzed 188 candidates for active surveillance who had undergone diffusion weighted magnetic resonance imaging before radical prostatectomy(More)
The purpose of this article was to determine the impact of time to undetectable prostate-specific antigen (PSA) for predicting biochemical recurrence (BCR) in patients with a positive surgical margin (PSM) following radical prostatectomy (RP). A PSM is an independent predictor of BCR; however, not all patients develop BCR later on. A retrospective analysis(More)
