A Clinical Study on Growth Rate of Urinary Calculi

Ryoo, Cheol Soo; Yang, Kou Young

Abstract

to elucidate growth rate of urinary calculi, a statistical analysis of 39 urinary calculi were undertaken and analysis with infrared spectroscopy was also performed in possible 31 cases. The men growth rate in length and width were obtained by measuring difference between size on the initial X-ray film and late film. The results were as followings. 1. Renal stones grew more rapidly than ureteral stones (p<0.01). On the growth rate of the ureteral stones, length showed more rapid growth rate than width (p<0.01). 2. Infected stones grew more rapidly than non-infected cases (p<0.01). 3. On the growth rate and compositions of stones, calcium phosphate stones showed most rapid growth rate and then calcium oxalate calcium phosphate stones and calcium oxalate stones were delayed in growth among 3 groups (p<0.05).
