Abstract
-
We treated 4 patients with uric acid calculi in the renal pelvis or ureter with alkaline fluid irrigation through percutaneous nephrostomy (PCN) tube. Initial presentations were anuria or severe flank discomfort, we performed PCN to relieve such obstructive symptoms caused by uric acid calculi. We tried to dissolve uric acid calculi with normal saline mixed to sodium bicarbonate through a PCN tube. The success of therapy is believed to be related to the direct and constant urinary alkalinization effect obtained with irrigation compared to be the intermittent alkalization that occurs when oral agent are used.
