Abstract
- Herein we have analysed retrospectively 16 patients with uric acid stone treated at Chung-Ang University Hospital during one and half year period from January 1987 to June 1988. Major presentation were flank pain(94%) and gross hematuria(44%). On urinalysis, all the patients shows microscopic hematuria and urinary pH were 5.0(8.1%) and 6.0(19%). Urate crystals were found in 44%. Mean serum uric acid level was 8.3 +/- 2.8mg% and mean uric acid amount of 24hr urine was 395 +/- 255mg. IVP, RGP, ultrasonography and CT were done for the diagnosis of uric acid stone. Medical treatment only was done in 7 patients(44%) using sodium bicarbonate and allopurinal. Surgical treatment was done in 6 patients(38%) when the stone size was large and urinary obstruction existed. ESWL was done in 3 patients(19 %). We think the medical treatment is an effective method for the removal of uric acid stone.
