Treatment of distal ureteral stones in the horse riding position.
From August 1986 through March 1987, 102 patients with 110 distal ureteral stones were treated in 110 sessions with the standard Dornier HM-3 lithotriptor in the so-called horse riding position. The majority of the patients (70 of 110, 63.7%) were treated for distal stones alone, whereas in a third (40 of 110, or 36.3%) treatment was performed for distal and upper stone localization during the same session. Additional treatment besides extracorporeal shock wave lithotripsy was necessary in 12.7% of the patients. Of the 110 patients 89.4% were without residual stones after a mean of 17.3 days. This modified position of the patient, which is specific to the Dornier HM-3 lithotriptor, makes possible treatment of distal ureteral stones with results comparable to those of endoscopic management but with less major complications (4.7%). A total of 7 patients had anal blood loss in the early postoperative period. Rectal bleeding ceased within 36 hours after treatment. The position also allows for treatment of stones at other, more proximal locations without great modifications to the position during the same session.
