A case of secondary anuria following the insertion of a double pigtail stent to treat an anuria due to a tumoral obstruction of the ureter is presented. Washing of the stent through a second ureteral catheter parallel to it proved the patency of the stent. Diuresis ensued at last by the administration of diuretics and leaving both the stent and the ureteral catheter in place. The literature is reviewed and discussed.

The authors report a case of anuria. The existence of an isolated pseudotumor of the pelvic ureter revealed a case of periarteritis nodosa. A segmental resection and a psoic bladder provided satisfactory functional recovery.

We experienced 1 case of obstructive anuria. This patient had received radiotherapy for uterine cancer. We performed unilateral cutaneous ureterostomy. Excretion of urine from the contralateral kidney occurred from the 17th postoperative day indicating improvement in renal functions. The possible mechanism for improvement of functions of the contralateral kidney is considered to be release of unilateral obstruction resulting in improvement in edema of tissues around kidney and ureter and remission of intravesical ureter obstruction caused by inflammation as a sequela of radiotherapy through improvement in inflammation.

A sixteen day old infant developed candiduria after surgery on a single functioning, hydronephrotic kidney with ureteropelvic junction stenosis. Masses of candida albicans caused obstruction of the ureter with acute anuria. Endoscopic relief of the obstruction together with aggressive antifungal therapy led to irradication of the fungal infection. This case history emphasizes the fact that candida infection in early childhood should be evaluated carefully. Unfortunately no guidelines are yet available for the indications and the preferred mode of treatment, and length of therapy of infantile renal candidiasis.

A 44-year-old man developed anuria 8 days after an operation for a perforated appendix. An intravenous pyelography showed delayed excretion on both sides with hydronephrosis, a right dilated ureter and no contrast passing to the bladder. On neither sides a ureter-catheter could be passed through the obstructions from below. By surgical intervention no ureter-catheter could be passed through the obstructions from above, and both ureters were drained with a T-tube. The benign obstruction was caused by a periappendicular abscess with inflammation and oedema of the ureteral and periureteral tissues. The condition was normalized within 7 days.

Retroperitoneal fibrosis is a disease which causes renal failure by obstruction of the ureters. The fibrosis may be benign or secondary to malignant disease. The clinical and radiological features of 30 cases have been reviewed. The symptoms are non-specific and diagnosis is often difficult. The most important features are back pain associated with a high ESR. Urography is diagnostic; the well known features are obvious dilatation of the pelvicalyceal system and ureter above the level of the obstruction. However, there is a spectrum of appearances corresponding to the duration of the disease and there may be only minimal dilatation of the pelvicalyceal system or no pelvicalyceal opacification at all. The progress of the disease is variable. Slow progress leads to chronic obstruction and chronic ill health. With more rapid progression, the patient may present with acute obstruction in anuria and, in such cases, urgent ureterolysis is necessary to conserve nephrons. Benign and malignant retroperitoneal fibrosis are often indistinguishable, clinically and radiologically, and laparotomy with biopsy is essential for diagnosis.

We report on 8 azotemic patients with anuria or progressive oliguria owing to bilateral uric acid lithiasis. In 7 patients the precipitating cause of acute obstructive renal insufficiency was choking of at least 1 distal ureter with numerous small uric acid stones. In 6 of these ureters contrast retrograde ureterography showed relief of obstruction, which was believed to be owing to the stone dissolution properties of the contrast medium used. In situ alkalization via nephrostomy catheters achieved dissolution of obstructing stones in 3 tracts and systemic alkalization dissolved the stones in 3 others. An operation was necessary in 4 cases of large calculi, all of which showed some radiodensity, either because of super added calcification or phosphatic incrustation, rendering dissolution unfeasible. Methods of management of the obstructed tract caused by uric acid stone disease are evaluated and discussed.

A 20-year-old woman had 18 hours of pain and anuria associated with a calcium oxalate stone impacted in the distal left ureter. The stone passed spontaneously and the urine output returned. There was no abnormality of the right kidney on excretory urography. We believe that this is a cause of reflex anuria not previously described. Severe pain may be the initiating event in this unusual but interesting syndrome and mechanisms proposed by previous authors are reviewed.

These operations, in which the risk is essentially ureteral, must be carried out in a urological rather than gynaecological way; the said ureter must be sought after a permanent, ureteral probe has been placed before the operation. We feel that a vaginography is more useful than a retrograde pyelography for diagnosing ureterovaginal fistulae. Another important indication is the need for an intravenous urography to be systematically carried out in the postoperative period of all pelvis operations. Only I.V.U. enables the discovery in time of ureteral lesions which would otherwise remain undiscovered too long. We feel that nephrostomy is an emergency therapy in cases of anuria and septic shock with a urinary focus. It is a safety measure for preventing kidney deterioration in ureter lesions which have remained undiscovered for a long time. In pelvic ureter lesions and providing that there is no vesical retraction, we perform a vesical psoization along with the ureterocystoneostomy (1). When the ureteral lesion is bilateral and the elasticity of the bladder enables us to do so, we perform a ureterocystoneostomy with vesical bipartition and psoization of both vesical wings. In cases of extensive, bilateral ureteral lesions associated with vesical damage such as: vesico-vaginal fistulae and retracted bladder, we perform a ureteroileocystoplasty and vesical stretching.

Comparative analysis of two types of ureterocystic anastomosis in kidney transplantation showed the advantages and shortcomings of the method developed at the Moscow Regional Scientific Research Clinical Institute. The new anastomosis fundamentally differs from the traditional Mebel-Shumakov method in the absence of sutures between the ureter and the bladder mucosa. This feature makes it possible to avoid injury to the bladder mucosa which is often changed in prolonged anuria and reduce the edema and ischemia of the terminal part of the ureteral graft. This facilitates adaptation of the anastomosis to polyuria which often occurs in the early postoperative period. The relatively simple techniques shortens the time needed for the operation. These advantages of the new method of ureterocystotomy are manifested by decrease of the total number of urological complications and the relative incidence of serious early urological complications like fistula of the ureterocystic anastomosis and necrosis of the ureter which most often lead to loss of the transplant and sometimes to death of the patient. The use of the anastomosis developed at the Clinical Institute, however, is attended by a relatively high incidence of ureteral stricture in the late-term postoperative period, evidently due to prolonged contact of urine with the bladder muscular coat and the ureteral adventitia. Thus, the more favorable results of ureterocystic anastomosis formed by the method developed at the Clinical Institute allow it to be recommended for further use in kidney transplantation.
