Abstract

Urolithiasis is one of the most common diseases of the urinary tract and the incidence has been increasing in recent years. The author made a clinical observation on 312 cases of clinical significance among the 375 cases of urolithiasis admitted to the Department of Urology, Presbyterian Medical Center, Daegu, Korea during the period from August, 1970 to July, 1976. The following results were obtained: 1. Among total admissions (1,400 cases), those with urolithiasis were 375 cases (26.8%), being the most common disease of the urinary tract. 2. Age distribution was between 2 and 85 years, showing the highest incidence in 21 to 50 years (74.1%). 3. Among 312 cases of in-patients, 225 cases were male and 87 female with 2.6 : 1 ratio. 4. Stones were located in ureter (69.2%), kidney(18.6%), bladder(9.0%) and urethra (2.9%). 5. Among those with ureterolithiasis, 62.5% of all cases were located in the lower third of the ureter. 6. Among those with renal stones, those with stag-horn calculi and bilateral stones were 25.9% and 3.5% respectively. 7. Managements included surgical intervention (61.9%), manipulation with baskets and ureteral catheters(25.6%) and other conservative(expectant) treatments (12.5%). 8. Pyuria was present in 30.1% and positive urine cultures with more than 100,000 colony per ml were obtained in 27.3% of 216 cases. 9. Serum calcium and phosphorus showed normal ranges in all cases. 10. Quantitative urinary calcium was elevated in 12.5% of 56 cases (more than 300 mg% per 24 hr) and phosphorus was reduced in 21.4% (less than 700 mg% per 24hr).
