[Renal hydatid cyst].

We present a case of urinary way fistulized renal hydatid cyst, which displayed itself clinically by repeated nephritic colics caused by the expulsion of calcified daughter vesicles. We make special mention of the diagnostic process and the surgical technique used, which included cystopericystectomy and anterograde ureteroscopy for the extraction of the calcified daughter vesicles at ureteral level.
