Medial Discoid Meniscus in Children: A Multicenter Case Series of Clinical Features and Operative Results.

Background: The discoid medial meniscus is a rare congenital anomaly of the knee. The literature is limited to small case series.

Purpose/hypothesis: Our purpose is to report the clinical manifestations and operative treatments of discoid medial menisci in children from multiple centers in North America.

Overall rate, location, and predictive factors for positive surgical margins after robot-assisted laparoscopic radical prostatectomy for high-risk prostate cancer.

We report the overall rate, locations and predictive factors of positive surgical margins (PSMs) in 271 patients with high-risk prostate cancer. Between April 2008 and October 2011, we prospectively collected data from patients classified as D'Amico high-risk who underwent robot-assisted laparoscopic radical prostatectomy. Overall rate and location of PSMs were reported.

The Tube 3 module designed for practicing vesicourethral anastomosis in a virtual reality robotic simulator: determination of face, content, and construct validity.

Objective: To better use virtual reality robotic simulators and offer surgeons more practical exercises, we developed the Tube 3 module for practicing vesicourethral anastomosis (VUA), one of the most complex steps in the robot-assisted radical prostatectomy procedure. Herein, we describe the principle of the Tube 3 module and evaluate its face, content, and construct validity.

Materials And Methods: Residents and attending surgeons participated in a prospective study approved by the institutional review board.

Factors affecting return of continence 3 months after robot-assisted radical prostatectomy: analysis from a large, prospective data by a single surgeon.

Purpose: In this study we identified preoperative or intraoperative factors responsible for the early return of continence after robot-assisted radical prostatectomy using data from a high volume center.

Materials And Methods: Data from 1,299 patients who underwent robot-assisted radical prostatectomy performed by a single surgeon from January 2008 to June 2010 were collected prospectively and analyzed retrospectively. Patients were categorized according to whether they regained continence (no pad and no urinary leakage) within 3 months and variables were then compared.
