Ureteral catheter system for renal function studies in conscious rabbits.
To overcome the problem of obstruction of ureteral catheters with blood clots, a ureteral catheter was constructed which had a double lumen. Irrigation of blood from the catheter was accomplished by perfusion of heparinized saline through a small inner catheter. In renal function studies performed in 12 rabbits using this system, no instances of catheter obstruction occurred.
