[Complications and limitations of ureteroscopy].

From 1985 to January 1990 a series of 298 patients with calculi of the ureter at various level were treated by ureteroscopy (lumbar 179; iliac 11; pelvic 108). We always performed the ureteral dilatation. After treatment all patients were-controlled with urography and, in particularly case (more than one ureteroscopy in same patient, complex stone) underwent also to TAC, RMN and cystography. The success rate for ureteroscopic removal calculi was 94%. We compared the complications rete between ureteroscopy and open surgical lithotomy: they were significantly less for ureteroscopic stone removal than ureterolithotomy. Ureteroscopy should be considered the method of choice in the management of ureteric calculi.
