[Massive residual stones after ESWL for staghorn cystine calculi were completely dissolved by oral administration of alkaline citrate: a case report].
A 62-year-old woman was referred to our hospital for bilateral renal stones. Ultrasonography (US) and computed tomography (CT) revealed bilateral staghorn calculi and atrophic left kidney. She had extracorporeal shock-wave lithotripsy (ESWL) for right renal stone during the first 6 months. However, ESWL was not effective and the patient did not want to continue this treatment. Her stone was composed of cystine. We started oral administration of alkaline citrate. Then massive residual stones were completely dissolved during the next 32 months.
