요로결석의 구성 성분에 대한 화학적 정성분석 = Chemical QULITATIVE Analysis of Urinary Calculi

다국어 초록 (Multilingual Abstract)

Objectives : Chemical constituent of urinary stone is important for the management and the prevention of recurrence. We performed chemical analysis of the urinary stone and investigatedits chemical constituent.
Methods : From January 2003 to December 2005, stone fragments were collected after extra-corporeal shock wave lithotripsy (ESWL, n=43), or removal by endoscopic procedure such as ureteroscopy (URS, H=93) and open surgical procedure such as cystolithotomy (n= 8). So we had stone fragments from 144 patients totally.
Results : 80 stone fragments were collected from male (55.6%), 64 stones from female (44.4%), and male to female ratio was 1.25 : 1. The mean age between males (mean age ; 47.2 years old)and females (mean age ,47.9 years old) was not different. The most frequently found location of urinary stones was ureter(91.0%) Of 144 patients in urine analysis,54 had pyuria (31.5fS). The most frequently found constituent in stone fragments was that of calcium(n=119 , 82.6%). The 2nd constituent was phosphate
(n=82 ; 56.9%). The 3 ͬ ͩ was uric acid(H=33 ; It.9%). The other constituents were ammonium(n=24 ; 16.6%) , carbonate (n=18 , 12.5%), magnesium
(n=11 ;7.6%). oxalate (n=3 ; 2.1%). Struvite stone
(MAP stone ; magnesium+ammonium+phosphate)were found in 5 patients (3.5%) All of 5 patients having strivite stone had pyuria(100%).
Conclusions : Calcium is the most common chemical constituent in urinary stone. Urinary infection was complication in 100% of patients with MAP stones.
