[Metaphylaxis and treatment of cystine lithiasis--personal experience]

The authors presented their own experience with treatment of cystine lithiasis in 7 patients, which has been performed during the course the past of ten years. Identification of cystine was performed by concrement submitted examination, using a polarizating microscope, and x-ray difractometric structural analysis. After stone extraction the patients were treated by a high fluid intake (diuresis over 2.5 l), alcalizating treatment involving citrates (Alkalit Spofa), and Penicilamin (Spofa), or Thiola (Santen) which are currently proved to be the most optimal approach. Recurrence of stones requiring percutaneous treatment, was observed in one of the patients during five years metaphylaxy. Another patient of the same group had three times stated cystine stone recurrence which passed spontaneously.
