Discordance of community and hospital ultrasound reports for urological abnormalities.

Introduction: In Ontario, community ultrasound clinics do not require the on-site presence of a radiologist at the time of imaging. In hospitals, a radiologist is always present for this step. We compared the discrepancy rate of community and hospital ultrasound reports in a urology practice.

Ultrahigh-pressure versus high-pressure angioplasty for treatment of venous anastomotic stenosis in hemodialysis grafts: is there a difference in patency?

Purpose: Ultrahigh-pressure (UHP) balloon catheters were compared with high-pressure (HP) balloon catheters to determine if there was a difference in patency after percutaneous transluminal angioplasty (PTA) of venous anastomotic stenoses.

Materials And Methods: A retrospective study was conducted from January 2001 to September 2005 that included 22 patients with synthetic hemodialysis grafts who underwent 110 PTA procedures for venous anastomotic stenoses. Data collected included graft configuration and location, percent stenosis, balloon type used, residual stenosis, and total access blood flow before and after intervention.
