Dissolution of Uric Acid Stones by Local Lavage

Abstract

Local lavage to dissolve uric acid calculi was used in cases of ureteral obstruction. In two cases the lavage was carried out via a catheter introduced into the ureter by means of a cystoscope, and in one case, in which cne kidney had been nephrectomized, with the aid of a T-drain introduced via ureterostomy. At the same time the patients ingested Uralyt U to alkalize the urine. The dissolution of the stones took 1–3 weeks. The solution used for the local lavage was isotonic sodium bicarbonate, pH 7.0–8.5.
