Comparative Study Between Chemical Analysis and Infrared Spectroscopy Analysis on Urolithiasis in Children / 대한비뇨기과학회지

ABSTRACT

Urinary calculous disease is unusual in children. During the last 7.5 years period, author has experienced and treated 18 children suffering from urinary calculus from January, l978 to July, l985 at the Department of Urology, Chonbuk National University Hospital. The results are summarized as follows; 1. The incidence of the pediatric urolithiasis (18 cases) was 2.7% of 666 urolithiasis patients andO.6 % of total 2930 in-patients. 2. The age of the patients ranged from 12 months to 15 years old, with the highest incidence in 6-10 in age (60%) and male to female ratio 3.5 1. 3. The locational distributions of urinary calculi were 15.8% in the kidney, 57.9% in the ureter 5.3 %, in the bladder, 21% in the urethra and 26.3% in lower urinary tract calculi. 4. The etiologies of urolithiasis were 77.7% in idiopathic, 5.5% in congenital and 16.8% in recurrent infection. 5. The clinical symptoms of urinary calculi were 25.8% in painful urination, 22.5% in flank pain, 6.5% in hematuria, 9.7% in frequency and 9.7% abdominal pain ete. 6. The size of stone was below 1.0cm in length 7 cases (70%), above 1.0cm in length 3 cases (30%). 7 The weight of urinary calculi was below of 0.4gm 6 cases (60%) and above of 1.0 gm 3 cases (30%). 8. Treatment consisted of Nephrolithotomy in l patient (5.3%), Pyelolithotomy in 6 patients (3l.6%), Ureterolithotomy in 2 patients (10.5%). Vesicolithotomy in 5 patients (=6.3%), and Spontaneorts passage in 5 patients (26.3%). 9. The results of chemical analysis and Infrared sphectroscopy of 10 urinary calculi are almost identical anti single calculi were 40%, mixed calculi were 60 %, calcium oxalate in 30% (3 cases), calcium oxalate and calcium phosphate in 30% (3 cases), calcium oxalate and calcium carbonate in 20%, (2 cases) calcium oxalate and uric acid in 10% (1 case), uric acid in 10% (1 case). The major component of urinary calculi was calcium phosphate oxalate.
