Do commonly used prostate medications alter prostate MRI and fusion biopsy performance?

Aims: To determine whether phosphodiesterase inhibitors (PDEi) or α-antagonists (AA) were associated with differences in region of interest (ROI) characteristics or prostate cancer detection on fusion biopsy (FB).

Materials And Methods: Records from 847 consecutive patients undergoing FB at three separate institutions over a period of 2 years were retrospectively reviewed. Associations between medication use, Prostate Imaging Reporting & Data System (PIRADS) scores, and ROI locations were assessed with ordinal logistic regression.

Initial Experience of Magnetic Resonance Imaging Fusion Biopsy in the Community Setting.

Introduction: Magnetic resonance imaging fusion biopsy is diagnostically superior to transrectal ultrasound guided biopsy for detecting clinically significant prostate cancer. Fusion biopsy has an expanding role at major academic centers. However, the reproducibility of outcomes in the community setting is unknown.

A rare case of a retroperitoneal lymphangioma causing chronic flank pain in an adult.

Retroperitoneal lymphangiomas are exceedingly rare and typically asymptomatic. We present a case of a 27 year-old female with chronic right flank pain and cross-sectional imaging showing a large multi-cystic mass located medial and inferior to the right kidney. The patient underwent an uncomplicated robotic-assisted, laparoscopic resection of the mass with final pathology showing a benign lymphangioma.

Ureteral function is modulated by a local renin-angiotensin system.

Purpose: Although many aspects of ureteral physiology are well characterized, the exact mechanism of ureteral smooth muscle modulation has not been fully established. In other smooth muscle contractility is modulated by angiotensin II (AngII). We determined the presence of a local ureteral renin-angiotensin system and characterized the functional role of AngII in ureteral smooth muscle.
