Abstract
|
|
|
The analysis of urinary calculi is an essential step in the examination and initial treatment of the patient with urolithiasis.
Among the various methods of stone analysis, the infrared spectroscopic analysis furnished a permanent record in a very short time. And it is an ideal method for qualitative identification and semiquantitative estimation of small fractions of
calculi.
A prospective review of stone analysis by infrared spectroscopy with KBr tablet method was performed in 101 cases of patients, who had been treated by ESWL at Pusan Paik Hospital from April. 1990 to October. 1990.
@ES The following results were obtained:
@EN 1. Mixed calcium was common than single calculus (1.3:1). The most common type of calculi was calcium oxalate-tribasic calcium phosphate(42%) and the most common type of single calculi was calcium oxalate (32%).
2. The incidence of alkaline urinary PH(7.0) in lithiasis patients was 39% and urinary PH in calcium phosphate group and magnesium ammonium phosphate group was more alkaline.
3. Among the serum biochemical parameters, only the mean value of magnesium was significantly higher in calcium stone group than in non-calcium group.
4. Pyuria was observed in 32% of all urinary stone patients, in 30% of calcium oxalate stone and in 22% of calcium oxalate-calcium phosphate stone.
