In kidney transplanted patients a clear coincidence was observed between clinical signs of allograft rejection and the presence in the peripheral blood of killer cells able to lyse either PHA lymphoblasts from the actual donor or selected unrelated individuals. In recipients with non-immunological complications such as leakage on the graft ureter or primary anuria caused by renal ischaemia, no cellular cytotoxicity against specific or selected target cells was observed. The specificity of this Cell Mediated Lympholysis in two of the cases reported could not be explained by the serologically detectable HL-A antigens, indicating the existence of other determinants of importance for the killing capability of in vivo produced effector cells.

Four children with anuria due to occlusion of both ureters by calculi are presented. A plain film of the abdomen revealed faintly radiopaque urinary calculi bilaterally in three patients. In the fourth case, one calculus was visualized in the right ureter, but further contralateral exploration showed an obstructing ureteral calculus in the left ureter as well. It is concluded that in children with acute anuria, the possibility of bilateral ureteral obstruction due to calculi should be the physician's first consideration.

A patient with bilateral localized amyloidosis of the ureters is described. This is the first case to be reported in which anuria was the presenting symptom, the second case with bilateral involvement and the thirteenth case of amyloidosis localized to the ureter. Careful urologic and hematologic followup is indicated.

In anuric dogs loaded with K by infusion with 2 meq KCl/kg per h until prelethal hyperkalemic cardiotoxicity appears, the extent of transmembrane K transfer depends on the origin of the anuria. Animals with bilateral ureter ligation transfer a mean of 1.2 meq/kg to intracellular fluid, while those with bilateral nephrectomy transfer more than 2.5 times as much (3.1 meq/kg). Further, if dogs with functioning kidneys are ureter ligated or nephrectomized after approximately 45 min of K loading, K transfer ultimately falls as infusion continues. The fall is precipitate and over 90% in ligated animals; but it is gradual, and only 10% in those that are nephrectomized. Finally, K transfer, because of the absence of insulin, is negligible in K-loaded pancreatectomized dogs with bilateral ureter ligation, but fairly substantial in pancreatectomized animals with bilateral nephrectomy. The data suggest that ureter ligation and hyperkalemia activate a renal mechanism that interferes with the transfer of infused K to intracellular fluid. The mechanism may involve the renin-angiotensin II-aldosterone system to a limited degree.

In a 19 year old man with a single kidney the development of a large Douglas' abscess was followed by anuria; The various causes are discussed. It is resonable to assume, that the obstruction resulted from longitudinal tension of the ureter over the iliace vessels (iliac sign).

We performed extracorporeal shock wave lithotripsy (ESWL) to 5 solitary kidney patients with upper urinary tract stones (4 kidneys and 1 lower ureter) using the EDAP lithotripter LT-01 and achieved 4 complete and 1 well results. The size of stones ranged from 8 mm to staghorn and trials were 1 to 10 units. We could accomplish perfect crushing and abortion of stones in the 4 renal stone patients without any adjuvant systems as ureteral stent but nephrostomy was needed in the 1 lower ureteral stone patient developed anuria. The values of blood pressure, hematology, blood chemical constituents and urine excretion enzymes at a month after the last ESWL were not so changed compared with those of preoperation and also excretory urogram showed favorable findings. In this series decreased renal functions by ESWL were not observed. We confirmed ESWL was an effective and a safe method even in the cases of solitary kidney patients and monotherapy without any adjuvants was possible.

Among the 652 consecutive renal transplants performed from January 1973 through December 1988, all graft failures within 60 days of transplantation were retrospectively analyzed. The 53 early failures were divided into four groups on the basis of pathologic findings in the removed transplant). 1) Irreversible vascular rejection (17 cases); in ten patients, this rejection occurred between the fourth and eight days and was manifested by uniform clinical features. 2) Thrombosis of the renal artery (18 cases), with several subgroups: a) early postoperative thrombosis (5 cases) with primary anuria; b) thrombosis following reoperation (6 cases) for urine leakage or occlusion; c) thrombosis with a clotting disorder,; d) and five cases of thrombosis with clinical manifestations of vascular rejection but with isolated thrombosis upon histologic examination. 3) Thrombosis of the renal vein (12 cases), with primary anuria in nine cases, and rupture of the kidney in three. 4) The last group includes six cases due to a variety of causes: one immediately non-viable -kidney, two severe, irreversible cases of tubulonephritis, one cortical necrosis secondary to circulatory collapse in the recipient, one complete necrosis of the ureter requiring removal of the transplant, and one immediate recurrence of hemolytic uremic syndrome. Among the risk factors for early failure, attention is drawn to the young age of the donor or recipient that increases the risk of thrombosis. Furthermore, the risk of vascular rejection was decreased in patients preventively treated by OKT3.

An 8-year-old boy who had suffered from recurrent stone formation since the age of 4 years, was admitted as an emergency due to anuria for a half day on November 20, 1986. Kidney-ureter-bladder film showed that the urethra was obstructed by a stone, and emergent cystoscopy was performed to remove it. He is the product of consanguinous marriage, his parents being first cousins. There was no family history of renal stone. Laboratory investigations showed hypokalemic, hyperchloremic metabolic acidosis. The ammonium chloride loading test revealed inability to acidify the urine and a markedly decreased excretion of titrable hydrogen ion and ammonium ion in the urine. These results indicate that this is a case of Type I renal tubular acidosis. His 24-hour urinary excretion of oxalate and glyoxylate were also markedly increased. There were no underlying causes leading to the development of secondary hyperoxaluria. These results also establish the diagnosis of Type I primary hyperoxaluria. The patient then received regimens of Polycitra 1ml/kg/day and Vitamin B6 50mg/day for 4 months. However, urinary stone developed again in this patient 4 months later. To our knowledge, Type I primary hyperoxaluria in association with Type I renal tubular acidosis has not been previously reported.

Anuria due to complete obstruction at the level of the ureteral meatus was encountered after bilateral ureteral reimplantation. The cause was thought to be due, at least in part, to excessive length of distal ureter drawn into the submucosal tunnel. At reoperation, both ureteral meatus were found to be stenotic and to project intravesically. Bilateral ureteral meatotomy was performed and proved to be curative.

Serious morbidity from renal transplant biopsy is reported to be infrequent. However, 4 of 43 patients who had renal transplant biopsy between July, 1981, and March, 1984, experienced anuria from upper urinary tract obstruction by blood clots. Although these clots usually dissolve, 3 patients (7%) experienced persistent clot anuria and deterioration of renal function. Awareness of this complication is important. Retrograde pyelography and ureteral catheterization are preferred primarily for diagnosis and treatment. Percutaneous techniques are reserved for those cases in which the ureter cannot be catheterized cystoscopically.
