Prostate Cancer: Interobserver Agreement and Accuracy with the Revised Prostate Imaging Reporting and Data System at Multiparametric MR Imaging.

Purpose: To evaluate accuracy and interobserver variability with the use of the Prostate Imaging Reporting and Data System (PI-RADS) version 2.0 for detection of prostate cancer at multiparametric magnetic resonance (MR) imaging in a biopsy-naïve patient population.

Materials And Methods: This retrospective HIPAA-compliant study was approved by the local ethics committee, and written informed consent was obtained from all patients for use of their imaging and histopathologic data in future research studies.

Off-clamp laparoscopic partial nephrectomy for hilar tumors: oncologic and renal functional outcomes.

Objectives: To present our experience demonstrating the feasibility of off-clamp laparoscopic partial nephrectomy (LPN) for hilar tumors and evaluate intermediate oncologic and renal functional outcomes.

Patients And Methods: A retrospective review of LPN cases in nine patients was performed. Hilar lesions were defined as renal cortical tumors in direct physical contact with the renal artery, vein, or both as identified on preoperative imaging and confirmed intraoperatively.
