We relate our experience about ureteritis, especially non specific ureteritis. The traumatic, radiation ureteritis will be discussed in others chapters. Most cases of ureteritis are infective, and may be due to any of the organism normally found in urinary tract infections, particularly Escherichia Coli, staphylococci, streptococci, enterococci, proteus and pyocyaneus. It is really primary, but it usually ascending from an associated cystitis, descending from pyelonephritis, or due to direct spread from and adjacent inflammatory lesion such as appendicitis or salpingitis. The infection may also reach the ureter by lymphatic spread, particularly from the prostate and seminal vesicles. Any associated abnormalities of the ureter, such as stricture, megaloureter, ureterocele, and so on, will naturally predispose to infective ureteritis. As ureteritis is rarely primary, the first step in treatment must be toward the elucidation and cure of any underlying lesion. Thus calculi, cystitis, pyelitis, and so on, will need appropriate therapy, and this in itself will considerably improve or cure the ureteritis, and specially in the more acute cases. In the chronic cases with stricture formation, dilation or even excision of the stenosed portion may be required. For the treatment of the strictures we want emphasize the role of the ureteral stenting thinking its use is necessary to preserve the renal function.

The action of indirect electrochemical blood oxidation with 0.06% solution of sodium hypochlorite on kidney and urinary inflammation was studied in experiments on 60 non-inbred rat females of 200-250 g body weight. The animals were intravesically infected through the catheter with E. coli and Ps. aeruginosa. 3 days later, after histological verification of acute pyelonephritis, ureteritis, cystitis, the animals were injected intraperitoneally 1.0 and 2.0 ml daily of sodium hypochlorite solution (control animals) or 0.89% solution of sodium chloride. Though no reliable decrease of the bacterial contamination was achieved, histologically, there was a marked reduction in morphological signs of the inflammation in the kidneys, ureter and urinary bladder on the first day after beginning of electrochemical blood oxidation with solution of sodium hypochlorite in experimental groups. In experimental group rats morphological signs of urinary and renal inflammation for both infections disappeared on days 7 and 10, respectively. In the control animals morphological signs of the inflammation remained after 10 days. Moreover, purulent inflammation was registered in the controls infected with Ps. aeruginosa.

A total of four patients underwent ureteral replacement using ileum without the antireflux mechanism for extensive ureteral loss from 1985 to 1995. The indications included surgical trauma, retroperitoneal fibrosis, ureteral obstruction due to abscess, and ureteritis. One case had bilateral reconstruction. The followup interval ranged from 3 to 14 years. Urinary infections were noted in 2 cases. One patient, who had urinary infections and neurogenic bladder, had symptoms, but, in all cases, serum creatinine was unchanged or decreased and the pyelogram was normal or showed mild hydronephrosis. Thus, the procedure was considered successful in all cases. This procedure provides excellent long-term results for reconstruction of ureter when the normal ureter cannot be used. Creation of the antireflux mechanism may not be necessary in patients with normal renal function.

In two cases the appendix was utilised as a substitute for part of the left ureter. Case one used the appendix as a conduit from the upper left ureter to the right one to treat the megaureter, and the other one used the appendix as a connection to join the two transected openings of the left ureter to treat the obstruction caused by the chronic ureteritis of the left ureter. Long-term observation after the operation showed satisfactory functions of kidneys. We suggested that the appendix is an autologus tissue whose active peristalsis, little mucous absorption along with its easy performance make this method highly valuable and practical.

We report a case of invasive cytomegalovirus (CMV) infection in the native ureter of a patient 7 years after liver-kidney transplantation. Previous reports of CMV ureteritis in transplant patients have involved only the allograft ureter, usually within 3 months of transplantation. The common characteristics of these patients, the possible risk factors, and the diagnostic findings of CMV ureteritis are discussed. Combined surgical and medical intervention are required for successful treatment.

Cystic Ureteritis is a very rare disease. It is more commun in elderly patients. This pathology is characterized by the formation of several submucous cystic in ureter, pelvis and/or bladder. We project the importance of the infectious and inflammatory factors as the disease etiology. We report a case of a woman with recurrent urinary tract infection, coral lithiasis and left ureteritis cystica. It is included a literature review and we explain the main clinical, diagnostic and therapeutic aspects.

A 2-day-old male foal developed uroperitoneum. Initial exploration of the abdomen via ventral midline celiotomy failed to localize the source of uroperitoneum. Bilateral nephropyelocentesis and antegrade urography were performed, and a defect in the right ureter and stenosis of the left ureter were identified. With the foal in dorsal recumbency in the Trendelenburg position, ureterorrhaphy was performed on the right ureter. After ureterorrhaphy, a ureteral catheter was maintained as a stent. The stenotic left ureter was transected, and ureteroneocystostomy was performed using a drop-in mucosal apposition technique. The ureteral catheter was removed 26 days after surgery. Histopathologic findings suggested that ureteritis of unknown origin was a possible initiating factor for stenosis of the left ureter. The drop-in technique for ureteroneocystostomy may be used successfully for ureteral transposition in horses. Ureterorrhaphy combined with the use of a ureteral stent may be used to repair ureteral defects in foals.

We report a case of intrinsic-type ureteral endometriosis in a 28-year-old woman. She visited our hospital, complaining of lower abdominal pain. Drip infusion pyelography (DIP) showed left hydronephrosis, and left retrograde pyelography revealed a filling defect of the left pelvic ureter. Biopsy under ureteroscopy showed chronic ureteritis. It was difficult to exclude a malignant tumor, and we performed left partial ureterectomy and uretero-ureterostomy. The pathological examination showed endometrial tissue in the submucosal and muscle layer, and we diagnosed it as intrinsic-type ureteral endometriosis judging from the findings of the ureteroscopy and the operation. After the operation, drip infusion pyelography showed the improvement of the left hydronephrosis and ureteral passage, and the right ovarian endometriosis was found by gynecologists. She received hormonal therapy with the luteinizing hormone releasing hormone agonist for about half a year, but the right ovarian endometriosis remained unchanged. This is the ninth case in the Japanese literature reported as intrinsic-type ureteral endometriosis.

Tissues from ureter and renal pelvis of 18 sows naturally (n = 15) and experimentally (n = 3) infected with Actinobaculum suis (former Actinomyces, Eubacterium suis) were studied using light and scanning as well as transmission electron microscopy. The results were compared with the findings from 11 clinically healthy sows as controls. The lesions in both the ureter and renal pelvis of naturally and experimentally infected animals were similar. In severe cases there were necrotizing ureteritis and pyelitis with accumulation of bacterial colonies in some cases. Several superficial epithelial cells were found phagocytosing necrotic debris. In mild cases the main lesions included epithelial cell hyperplasia, desquamation of the superficial epithelial cells and goblet cell metaplasia with intraepithelial cyst formation. The goblet cells were found in the superficial as well as in the intermediate cell layers. Generally, it was observed that severe purulent ureteritis and pyelitis/ pyelonephritis in sows were to be expected only in mixed infection of A. suis with other bacteria. The findings were compared and discussed with the changes in the infected urinary bladder of sows and the alterations induced by urinary tract infection in man.

Henoch-Schonlein purpura (HSP) is a systemic vasculitic disorder involving both arterioles and capillaries. Although mainly a disease of early childhood, it can occur at any age. HSP is typically recognized as a syndrome with four major components: rash, joint manifestations, abdominal symptoms and renal disease. It is usually a mild condition with a tendency to relapses and generally has a good prognosis. Occasionally, however, it takes on an aggressive course. Gastrointestinal involvement is potentially the most serious complication of HSP. It may mimic an abdominal emergency and in its severest form result in small bowel infarction and/or perforation. Renal manifestations range from asymptomatic haematuria and/or proteinuria through a nephrotic syndrome to progressive glomerulonephritis leading to end stage renal failure. Apart from the major components outlined above, HSP may affect almost every other bodily organ. Vasculitis involving the myocard, lungs (pulmonary haemorrhage), ureter (stenosing ureteritis) and nervous system have been reported. We describe a case of HSP in a 50 year old woman which was complicated by the development of necrotizing crescentic glomerulonephritis and a left hemiparesis due to cerebral vasculitis. Interestingly, this patient had first appeared at the age of 9 years with a nephrotic syndrome and had been diagnosed by renal biopsy at the age of 31 as IgA nephropathy (IgAN). On her current admission, steroid and immunosuppressive therapy resulted in an improvement of renal function and an almost complete disappearance of her neurologic deficit.
