Percutaneous chemolitholysis of cystine stones. Possibilities for ambulatory procedure.

We report on a patient with symptomatic cystine calculi in a solitary kidney in whom percutaneous pelviocaliceal irrigation with tromethamine-E was performed as an ambulatory procedure for a significant period of time. Our experience demonstrates that in selected cases this form of treatment is well-tolerated.
