A clinical study was made on 47 cases of the lower urinary tract calculi during 5 years from 1983 to 1988.
The results were as follows:
1) 61.7% of cases(29) were bladder calculi and 38.3% of cases (18) were urethral calculi. The average patient age was 49.4 years, with a range of 6 to 81 years and the sex ratio was about 15:1, 44 males and 3 females.
2) The combined diseases were B.P.H. in 12.8%, other urinary stone in 10.6%, D.M. in 6.4% and urethral stricture in 6.4%.
3) The clinical symptoms were dysuria in 68.4%, hematuria in 59. 6%, frequency in 53.2%, interruption of urinary stream in 31.9% and urinary retention in 19.2%.
4) The microscopic hematuria showed in 78.7% and pyuria revelaed in 44.7%. Klebsiella, Pseudomonas, Staphylococcus, Streptococcus, Enterobacter, E. coli and candida were detected on the urine culture.
5) 72.4% of cases were single bladder stone and single urethral stone was in 94.4%. The most common size was 1-2 cm in diameter in 23 cases (48.9%).
6) The results of chemical analysis of 19 urinary calculi showed Ca-oxalate in (31.6%), Ca-oxalate phosphate in 4(21.1%), Ca-carbonate in 4(21.1%), Ca-phoaphate in 2(10.5%), Mg-ammonium phosphate in 2(10.5%) and the mixed type of Ca-oxalate and cystine in 1(5.3%). The major component of the lower urinary tract calculi was Ca-oxalate.
7) The most frequent surgical intervention was litholapaxy in 34 cases (72.3%).
