Extracorporeal shockwave lithotripsy for ureterolithiasis in patients with urinary bilharziasis: efficacy and variables that influence treatment outcome.

Objectives: Schistosomiasis affecting the ureter is commonly accompanied by ureteric dilatation with or without ureteric stricture and altered ureteric wall motility that can influence extracorporeal shockwave lithotripsy (ESWL) results. This study attempts to identify variables that may influence the outcome of ESWL in the treatment of ureterolithiasis in patients with urinary bilharziasis.

Patients And Methods: Forty-three patients with urinary schistosomiasis and ureterolithiasis treated with ESWL were reviewed.
