OBJECTIVE: To test the hypothesis that targeted biopsy has a higher detection rate for clinically significant prostate cancer (csPCa) than systematic biopsy. We defined csPCa as any Gleason sum ≥7 cancer. In patients with Prostate Imaging Reporting and Data System (PI-RADS) 3 lesions, to determine if factors, such as prostate-specific antigen density (PSAD) and prostate health index (PHI), can predict csPCa and help select patients for biopsy. MATERIALS AND METHODS: We report the first series of targeted biopsies in Southeast Asian men, with comparison against systematic biopsy...

INTRODUCTION: During percutaneous nephrolithotomy (PCNL), elevated renal pelvic pressures (RPPs) may spread infection through pyelovenous backflow whereas decreased pressures can hinder observation and increase bleeding. The purpose of this study was to evaluate the effects of multiple access tracts and different sized endoscopic equipment on RPP in a porcine model. MATERIALS AND METHODS: RPP was measured in one- vs two-tract access, rigid vs flexible nephroscopy, and suction vs no suction...

INTRODUCTION AND OBJECTIVE: With the peritoneum acting as a natural surface for lymphatic reabsorption, transperitoneal robot-assisted radical prostatectomy (tRARP) is thought to be associated with a lower incidence of symptomatic lymphoceles (SLs) compared with its extraperitoneal counterpart (eRARP) when bilateral pelvic lymph node dissection (BPLND) is performed. In this study, we aim to determine if there is a difference in SL formation and characteristics between the two approaches...

PURPOSE: Greater visual contrast between calculi and tissue would improve ultrasound (US) imaging of urolithiasis and potentially expand clinical use. The color Doppler twinkling artifact (TA) has been suggested to provide enhanced contrast of stones compared with brightness mode (B-mode) imaging, but results are variable. This work provides the first quantitative measure of stone contrast in humans for B-mode and color Doppler mode, forming the basis to improve US for the detection of stones...
