Effects of administration of local aminophylline on patients undergoing ureteroscopic lithotripsy.

Introduction: The presence of ureteral stones can cause pain, infections of urinary tract and hydronephrosis, resulting in the loss of renal function. For two decades, Ureteroscopy and laser stone fragmentation (URSL) attained a big rise and is the first line management for large ureteric stones and renal stones up to 2 cm. The present study was conducted to assess the success rate of ureteroscopic lithotripsy in treatment of ureteric calculus after local administration of aminophylline.
