Purpose: While higher radical prostatectomy hospital and surgeon volume are associated with better outcomes, the effect of provider volume on health care costs remains unclear. We performed a population based study to characterize the effect of surgeon and hospital volume on radical prostatectomy costs.

Materials And Methods: We used SEER (Surveillance, Epidemiology and End Results)-Medicare linked data to identify 11,048 men who underwent radical prostatectomy from 2003 to 2009.

Background: Large prostate size, median lobes, and prior benign prostatic hyperplasia (BPH) surgery may pose technical challenges during robot-assisted laparoscopic prostatectomy (RALP).

Objective: To describe technical modifications to overcome BPH sequelae and associated outcomes.

Design, Settings, And Participants: A retrospective study of prospective data on 951 RALP procedures performed from September 2005 to November 2010 was conducted.

Background: Apical dissection and control of the dorsal vein complex (DVC) affects blood loss, apical positive margins, and urinary control during robot-assisted laparoscopic radical prostatectomy (RALP).

Objective: To describe technique and outcomes for athermal DVC division followed by selective suture ligation (DVC-SSL) compared with DVC suture ligation followed by athermal division (SL-DVC).

Design, Settings, And Participants: Retrospective study of prospectively collected data from February 2008 to July 2010 for 303 SL-DVC and 240 DVC-SSL procedures.
