Abstract:
We have analyzed 100 urinary calculi by chemical analysis, which obtained from the patients admitted our department during the period from March, 1981 to February, 1983. The following results were obtained: 1. The results of chemical analysis of 100 urinary calculi revealed calcium oxalate phosphate in 43%, calcium oxalate in 19%, calcium phosphate in 15%, ammonium phosphate in 12%, carbonate calcium oxalate phosphate in 7%, uric acid in 2%, acid + calcium phosphate in 2%. 2. 40 of 100 patients with urinary stones showed bacteriuria and Staphylococcus epidermidis was the most frequent organism. 3. The causative diseases of the urinary stones were renal tuberculosis 4 cases, neurogenic bladder in 4 cases, urethral stricture in 3 cases, BPH in 1 case and hyperparathyroidism in 1 case. 4. The incidence of high urinary calcium amount was greater in lithiasis group(43%) than in control group(17%) The incidence of high urinary calcium amount in lithiasis group was as following order: calcium oxalate phosphate in 55.8%, calcium phosphate in 46.7%, calcium in 42.1% and ammonium phosphate in 28%.
