Factors affecting stone clearence for inferior renal pole calculi

Abstract

Factors affecting stone clearance were investigated on intravenous urograms obtained from 119 patients having single unilateral lower calyceal stone. On intravenous urograms lower infundibulopelvic angle, lower infundibulum diamter and inferior calyceal length were measured for calculons and noncalculous kidneys and compared with 40 patient control group. When we consider lower infundibulopelvic angle statistically significant difference was not present between calculous kidneys and the control group whereas lower infundibulum diameter and inferior calyceal length were significantly (p
