Extracorporeal Shock Wave Lithotripsy in the Prone Position: A Useful Technique in Anteriorly Situated Stones
Stones in the iliac ureter, in horseshoe kidneys, or in pelvic kidneys are anteriorly situated compared to renal and lumbar ureteral stones so their positioning with the Dornier HM3 lithotripter is sometimes not possible in the supine position. However, by placing the patient in the prone position, it is easy to put the stone into the second focus of the generator. In such a position, 36 patients with iliac ureteral stones, five with horseshoe kidneys, and one with an ectopic pelvic kidney were treated with good results and without complications. The treatment of the ureteral stones by the HM3 became feasible by changing the position of the patients according to the position of the stone: supine for lumbar, prone for iliac, and sitting for pelvic ureteral stones.
