Caliceal stones; fate of shock wave therapy with respect to stone localization

Abstract

In a retrospective analysis, results of extracorporeal shock wave lithotripsy (ESWL) treatment were evaluated in patients with renal stones according to caliceal localization of treated stones. 198 patients underwent ESWL with the Dornier MPL 9000 were analyzed in regard to the success rate, comp¬lication rate, residual fragments, regrowth and recurrence rates. Today 210 caliceal calculus located in different por¬tions'of kidney are being comparatively evaluated. No major complications were noted during or after ESWL. Some minor complications such as flank pain, renal colic, hematuria were observed. Flank pain was observed during ESWL treatment especially in patients with upper stones. Although stone free and residual fragment rates were similar in pelvic, upper and middle calices, patients with lower caliceal and pelvi-caliceal stones had high residual fragment rate and lower stone free rate. Patients with sto¬nes in the lower calices or pelvi-calices had recurrence and regrowth rates (p
