Double-lumen central venous catheter for percutaneous ureteral perfusion studies
1Department of Radiology, Valley Presbyterian Hospital, Van Nuys, CA 91405.
Abstract:
A commercially available double-lumen central venous catheter that can be inserted over a 0.018-inch guide wire was used for ureteral perfusion studies in three infants. Complications or difficulties were not encountered in any patients. This technique allows simultaneous monitoring of perfusion and intrarenal pressure and requires only a single puncture of the renal pelvis with a 21-gauge needle.
