    Stone research indicates URS over ESWL trend continuing

    This article is part of the State of Urology 2014

    Dean G. Assimos, MDDr. AssimosAt the 2012 AUA annual meeting, researchers reported that ureteroscopy had overtaken extracorporeal shock wave lithotripsy (ESWL) as the treatment of choice for kidney stones. Look for research at this year’s meeting showing that trend is ongoing.

    “Shock wave lithotripsy utilization is on the decline in both children and adults, while ureteroscopic stone removal is increasing in both cohorts,” said Dean G. Assimos, MD, professor and chair of urology at the University of Alabama, Birmingham.

    Another study identified by Dr. Assimos will show that “flexible ureteroscopic stone removal is an effective and safe method of treating patients harboring proximal ureteral stones,” he said.

    Other high-interest abstracts in stone disease treatment listed by Dr. Assimos will demonstrate that “burst wave” ultrasound lithotripsy may effectively fragment stones extracorporeally without inducing significant tissue injury; a newly developed device may limit stone fragment migration during lithotripsy undertaken during percutaneous nephrolithotomy; and steroids appear to improve results with medical expulsive therapy in patients with distal ureteral stones only when administered with an alpha-blocker but not when given alone.

    Here are Dr. Assimos' top abstract picks from the 2014 AUA annual meeting:
