Urologic applications of angiographic guide wire and catheter techniques

Abstract

A technique is described using angiographic guide wires and catheters in combination with endoscopy. Obstruction of 9 ureters in 7 patients was managed successfully with this technique. The ureters in these cases were inaccessible otherwise because of unusual ureteral position or severity of obstruction. The method allows placement of angiographic guide wires and catheters past ureteral obstacles when standard urological retrograde procedures are not feasible technically.
