Abstract
We treated 34 patients with staghorn calculi by fiberoptic transurethral nephrolithotripsy with a flexible nephroureteroscope and an electrohydraulic lithotriptor. Of the 34 patients 30 (88.2%) were treated successfully. There were 17 patients each with complete and partial staghorn calculi. There was no difference in the success ratio and the rate of residual fragments between the 2 groups. However, post-procedural fever, sepsis and extrapelvic extravasation were observed more frequently in patients with complete than with partial staghorn calculi. Countermeasures to avoid complications must be developed in the future. However, we believe that fiberoptic transurethral nephrolithotripsy is a safe and effective treatment for staghorn calculi. This procedure also should be recommended, as well as the combination of percutaneous nephrolithotomy and extracorporeal shock wave lithotripsy.
