[The treatment of calculi in the iliac segment of the ureter by extracorporeal high-energy shockwave lithotripsy].

Experience is recorded with the treatment of calculi in the iliac segment of the ureter by extracorporal lithotripsy with high-energy stroke waves with lithotriptor of the firm "Dornier", model HM-3. For a period of 2 1/2 years 18 patients at mean age 38 years have been treated. Retrograde catheterization was always performed before lithotripsy. Successful reposition was achieved in 6 patients. In all others lithotripsy was performed in prone position. Special supporting cushions were manufactured and used; they helped for a more stable position of the patient on the stand, facilitate calculus positioning, the load to the knee joints is reduced, the fluoroscopic time is shortened, thus reducing the radiation load to patient and attending personnel. All patients received antibacterial and spasmolytic therapy. The mean length of stay in the clinic was 3.2 days. The results were good in 94.1 per cent of the cases. No early or late complications of urologic or other nature were observed.
