Ultrasound Ureterolithotripsy Utilizing a 10.5-French Rigid Ureteroscope and a 2.5 Wire-Probe Transducer
Between July, 1986 and July, 1987, 128 patients with large impacted ureteral stones or persistent Steinstrasse required ureterolithotripsy at UCLA (Table 1). Indications were: failed stone manipulation with or without ESWL for stones located a) above the iliac crest, b) in the true pelvis, c) in the “stonecracker’s nomansland” between the iliac crest and pelvic brim, and d) in the management of ureteral Steinstrasse when the debris did not pass spontaneously within eight weeks after insertion of a percutaneous nephrostomy (PCN)-tube. Of the stones treated, 29% were located above the iliac crest, 24% in the stonecracker’s nomansland, and 47% in the lower third of the ureter (Table 2).
