Abdominal ultrasonography was performed on a caprine doe with anorexia, dysuria, and a palpable abdominal mass. Ultrasonography of a large firm mass situated cranial to the pelvic brim revealed a distended urinary bladder, which was confirmed by a dynamic bubble study. The left kidney had a large anechoic renal medulla and dilated renal pelvis and ureter consistent with ureteropyelectasia. Necropsy confirmed the existence of hydronephrosis and hydroureter, as well as cystitis, pyelonephritis, and partial urinary tract obstruction. The cause of the obstructive uropathy was a mass of fibrous tissue that obliterated the uterine cervix and partially obstructed the urethra and left ureter. The cause was presumed to be a cervical trauma from dystocia and forced extraction of a kid, with subsequent chronic fibrosis.

A 64-year-old man was hospitalized for massive bleeding from the cutaneous ureterostomy. He had undergone pelvic exenteration with the ureterostomy for rectal cancer invading the bladder five months previously and retrograde ureteric catheters were inserted bilaterally into the ureters. An aortography revealed a pseudoaneurysm of the abdominal aorta in the region transversed by the left ureter. He was successfully treated by en bloc resection of the aortoureteric fistula and the left ureter and repair of the aorta by Dacron patchplasty. Left nephrectomy was also performed because of pyelonephritis. He has had no signs of cancer recurrence or graft infection five years after this operation.

The results of treatment of 41 children with vesical exstrophy were analysed. Four types of surgeries were performed: 1) transplantation of Lieutaud's triangle into the sigmoid (n = 19); 2) its transplantation into the semi-isolated part of the sigmoid (n = 7); 3) ureteral transplantation into the sigmoid (n = 3); 4) the formation of the urinary bladder and ureter from the adjacent tissues (n = 12). In the first group 2 children died, 6 patients had no clinical signs of chronic renal or ureteral inflammation for the period of 5-17 years, the remaining 11 patients had pyelonephritis. In the second group 5 children were apparently healthy for 1-3 years after the operation, one child developed pyelonephritis, one child died from pneumonia. In the third group 2 patients were apparently healthy 1.5-2 years after the surgery, 1 child developed pyelonephritis. A great number of complications such as sutural incompetence followed by fistulization or enuresis made the authors avoid the fourth type. Thus, while forming an urointestinal anastomosis, preference is given to transplantation of Lieutaud's triangle or ureters proper into the semi-isolated segment according to the antireflux methods, if there are strictures in their distal portions.

A case of xanthogranulomatous pyelonephritis (Stage-I: Nephric) with ureteral involvement is described. The patient had undergone right nephrectomy with the working diagnosis of calculus pyonephrosis and non-functioning kidney. Histopathological examination of the nephrectomy specimen revealed xanthogranulomatous pyelonephritis confined to the kidney and non-contiguous involvement of ureter. Post-operative recovery was uneventful and there had been no evidence of disease recurrence till one year's follow-up.

After initial scepticism about its reality and despite a few disagreements, many authors now recognize the ovarian vein syndrome as a separate clinical entity, secondary to ureteral obstruction caused by dilation of the ovarian veins, which may cause lumbar pain, recurring pyelonephritis and/or lithiasic complications. The right side most frequently is affected because anatomical configuration of the right ureter is more susceptible to compression, and in fact, pregnancy appears to be an essential initiating or exacerbating factor. Thus, this anomaly might explain why painful and infectious manifestations and hydronephrosis so often develop on the right side (in over 95 p. cent of cases) during pregnancy. Its diagnosis thus must be known to be able to envisage its possible onset, by taking a careful history, and may be confirmed by certain radiological examinations. The latter, as well as treatment, depend on whether or not the patient is pregnant, its term, as well as severity of symptoms. Hence, erroneous diagnoses and incorrectly oriented surgical procedures may be avoided, while appropriate therapy is effective.

A cystadenoma or a cystadenocarcinoma arising from the renal pelvis is a rare neoplasma and, so far as is known, only two cases have been reported in the literature (Arcadi, 1956, and Ross, 1985). Discussed herein is a case of a 63-year-old woman who developed a mucinous nephrosis, due to a marked retention of mucin produced by a tumor. The ureter as well was found to be involved. The histogenesis of an adenocarcinoma, which includes a cystadenoma and a cystadenocarcinoma, most likely is due to a glandular metaplasia, associated with urolithiasis and pyelonephritis. In this specific case, the patient revealed a history, fifteen years earlier, of renal calculi and pyelonephritis.

The present study is a review of the results of Cohen's operation performed on 43 ureters in 32 children. Treatment results were assessed through the comparison of cystographic and 131I-hippuran renographic findings obtained before and after surgery. Urodynamic recovery in the affected ureter was demonstrated in all children. One year after surgery, there was no improvement in the activity of the resected kidney in 37% of patients. In the remaining patients, secretion improved by 10-13% in the affected kidney. Seventeen children returned for follow-up examination 2 years after surgery. The activity of the affected kidney and the contralateral one improved in 13 of 17 patients. There was no upper urinary retention due to ureteral stricture in any of the children. The rate of recurrent vesico-ureteral reflux (VUR) was 5.3%. Augmentation or persistence of purification deficiency in the affected kidney, detected in 12 patients at first postoperative follow-up, was qualified as a result of aggravated chronic pyelonephritis rather than that of surgical complications related to methodologic specifics. This assumption was verified by the results of the next follow-up examination 2 years after surgery. Therefore, Cohen's method can be recommended for large-scale application in the treatment of VUR in children and is expected to essentially reduce the rate of relapses and improve the standards of surgical care of children with this grave disease.

The authors report the case of a patient with primary bilateral mega-ureter presenting with recurrent pyelonephritis due to reflux occurring after 3 successive reimplantations. Transposition of the right kidney into the homolateral iliac fossa allowed correct anti-reflux with a good clinical, radiological and bacteriological result with a follow-up of 3 years. Renal auto-transplantation represents a last resort solution in certain extreme situations when other simpler procedures are impossible and when preservation of the kidney is essential (solitary kidney or bilateral lesions).

Authors have studied in apostematous pyelonephritis induced by the ligation of the ureter and the intravenous injection of E coli bacteria the localization and elimination with time of the pathogen. The pathogen was demonstrated by light and electron microscopy, its parietel antigen was localized with the light microscopic peroxidase antiperoxidase and post-embedding electron microscopic immunogold techniques. Two days after inoculation the suppurative inflammation of tubulo-interstitial foci was observed; in the capillaries, interstitium, and tubuli, free and phagocyted bacteria were encountered. In the interstitium, in the proximal tubuli and in the capillary space of some glomeruli bacterial groups were observed. Intracapillary bacteria were attached by their outer wall to the surface of endothelial cells. In the tubuli this adherence occurred with pili or with the outer layer of bacterial wall. From the seventh day after inoculation macrophages containing PAS-positive globuli appeared in the interstitium. Under the electron microscope these globuli proved to be features composed of myelin figures of phagolysosomal origin. Globuli and the myelin figures possessed an E. coli antigenicity. Thirteen weeks after inoculation E. coli antigen positivity was found in the cytoplasm of inflammatory cells in the tubular walls and in the suppurative cylinders, The organism was apparently unable to eliminate the materials derived from the pathogenic microorganisms.

A case of emphysematous pyelonephritis with septic shock was present in a 58-year-old diabetic woman. The spontaneous production of gas was present within the right renal pelvis in kidney-ureter-bladder X-ray. The patient's condition deteriorated rapidly after admission, became complicated with acute renal failure, disseminated intravascular coagulation and acute respiratory failure. Transurethral drainage of the pelvis using a 6 Fr. UPJ occlusion balloon catheter and endotracheal intubation with respiratory assistance were performed as a life-saving procedure. The optimal therapy with surgical or conservative approach for such a severe condition is discussed. The use of transurethral drainage of pelvis as a non-invasive treatment is suggested.
