OBJECTIVE
To analyze the utility of chemolysis and the double-J ureteral catheter in patients with uric acid calculi.
METHODS
The study comprised 30 patients (28 men and 2 women) treated with chemolysis for uric acid calculi and who consulted for renal colic. The indication for placement of a double-J ureteral stent were pain, moderate-to-severe hydronephrosis, fever and urinary tract infection. The calculi were < or = 10 mm in size and were located in the renal pelvis (3), upper ureter (5), middle ureter (2) and lower ureter (23).
RESULTS
The uric acid calculi were dissolved with intravenous and oral combination chemolysis. The double-J catheter was useful in the cases with urinary tract obstruction, fever or urinary tract infection.
CONCLUSIONS
Medical treatment is useful in the management of uric acid calculi. The double-J catheter is beneficial in patients with urinary tract obstruction.
