Kim, Soo Chang

Abstract

A clinical study was made on 53 cases of urinary lithiasis among the total number of 392 inpatients during the 3 years from January, 1968 to January, 1971, and 17 urinary calculi, safely reserved during the same period in our department, were analyzed by a chemical method. The results were as following: 1. The incidence of urinary calculi was 13.5 per cent, the all cases were male. 2.31 cases of urinary calculi were found in R.O.K.A. personnel and 22 cases were found in Korean Army personnel in Vietnam War. 3. The age of patients ranged from 21-30 years in approximately 90.5 per cent. 4. The location of urinary calculi was in the ureter in 54.7 per cent, kidney, 30.2 per cent, bladder, 13.2 per cent, and urethra, 1.9 per cent. 5. The most favored predilection of ureteral stone was lower third of ureter in approximately 51.7 per cent of all cases. 6. In a number of urinary calculi in each location 88.8 per cent was single. The most common size, was below 0.6cm in its diameter on 16 cases (34.1 per cent), and weight, below 0.5gm. on 20 cases (42.3 per cent). 7. The clinical symptoms of upper urinary tract lithiasis showed flank pain in 91.1 per cent, hematuria 37.7 per cent, and generalized weakness 15.5 per cent, but in lower urinary tract, painful urination was in 87.7 per cent, urinary frequency in 62.5 per cent, and hematuria in 37.5 per cent. 8. The microscopic hematuria showed in 90.6 per cent, its incidence was higher in lower urinary tract calculi, and pyuria was revealed in 30.2 per cent. 9. The most frequent surgical intervention was ureterolithotomy in 43.5 per cent (23 cases). 10. The results of qualitative analysis of 47 urinary calculi showed a mixed type of calcium phosphate and calcium oxalate in 48.9 per cent, calcium oxalate in 12. 8 per cent, calcium phosphate and calcium carbonate in each 8.5 per cent of the cases. The major component of urinary calculi was calcium phosphate-oxalate.
