Experiments involving injection of radio-iodinated albumin into the left renal arteries or left ureters of dogs indicate that the renal lymphatics are capable of a major contribution in returning to the circulation albumin (or other large molecules) escaping from renal capillaries. I131-albumin was injected into the jugular vein of controls or into the left renal artery or in retrograde manner into the left ureter of female dogs. Experimental groups included those with no obstruction, occlusion of left renal veins or left renal lymphatics, or both. Collections were made from the right femoral artery, both renal veins, thoracic duct and both ureters at frequent intervals for 2 to 4 hours. Data analysis included I131 concentration, specific activity, rate of recovery and selected ratios. After renal arterial injection, the percentage of I131 recovered in thoracic duct lymph of dogs without renal venous obstruction was 5 to 10 times that recovered in those that received injections into the jugular vein. In dogs with renal venous obstruction, recovery from the thoracic duct was 10 to 1,000 times that in control dogs. Most of the differences occurred during the first hour, after which time as recirculation and redistribution occurred the rates of appearance in thoracic duct lymph in each group were similar. The differences in the ratios of concentration in thoracic duct lymph to concentration in femoral arterial blood were also much greater when the renal vein was obstructed than in dogs with no obstruction. The greater return of albumin through the thoracic duct in those with impeded renal venous outflow was probably related to both sequestered concentration and increased intrarenal pressure.(ABSTRACT TRUNCATED AT 250 WORDS)

Ureteroarterial fistulae (UAFs) are rare but potentially life-threatening entities that require a high degree of suspicion for diagnosis followed by prompt intervention. This case report describes the successful management of the oldest woman to-date presenting with intermittent hematuria, secondary to a fistula between the ureter and internal iliac artery, which was subsequently resolved by coil embolization. Morbidity and mortality associated with UAFs can be decreased by increasing awareness of this rare but fatal complication. Our review of the medical literature indicates that this is the oldest woman reported to have developed a UAF after radiation therapy and chronic ureteral stent exchange, as well as the first reported management of a UAF by interventional cardiologists.
