1/6. Primary localized amyloidosis of the ureter and bladder managed by ileal interposition.amyloidosis of the ureter is a rare condition. It is even rarer when it involves both the ureter and bladder. The case presented is the second known case of combined amyloidosis of the bladder and ureter and the first combined case to be treated successfully by ileal ureter replacement. Historically, amyloidosis of the ureter has been treated by nephroureterectomy. Based on the benign nature of the disease, amyloidosis of the ureter is optimally treated with a kidney-sparing procedure such as ileal ureter replacement.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/6. Eosinophilic ureteritis associated with eosinophilic cholangitis: a case report.Eosinophilic infiltrate of the urinary tract is rare. We report on a patient with eosinophilic cholangitis who later had eosinophilic ureteritis. This case emphasizes the potential serious nature of eosinophilic ureteritis, which often presents with complete ureteral obstruction. The literature pertaining to eosinophilic ureteritis and eosinophilic biliary disease is reviewed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/6. Fibroepithelial polyp associated with congenital ureteral diverticulum: report of 2 cases.We report 2 cases of a single fibroepithelial polyp in conjunction with ureteral diverticula. Ureterorenoscopy is valuable in the identification of the benign nature of these lesions preoperatively to avert unnecessary nephroureterectomy. The etiology of fibroepithelial polyps remains unknown, although many theories have been proposed. Recent evidence has suggested that these lesions may be a developmental anomaly. Congenital ureteral diverticula also are thought to be of developmental origin. We hypothesize that fibroepithelial polyps and congenital diverticula of the ureter are part of a spectrum of the same developmental anomaly.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/6. Ureterocutaneous fistulas secondary to urinary calculous disease.Fistulas of the ureter are uncommon and are usually secondary to trauma or iatrogenic in nature. Spontaneous rupture of the ureter is rare, usually ending in a periureteral abscess. Two cases of spontaneous rupture of the ureter secondary to calculous disease resulting in ureterocutaneous fistulas are described.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
5/6. Ureteritis cystica causing obstruction.We have described a 58-year-old man in whom an unusually fibroblastic ureteritis cystica at the ureteropelvic junction caused partial obstruction and ureteral colic. Local resection resulted in relief of renal pain and improved urinary flow through the ureter. Explanations for the unusual nature of the lesion and only partial relief of obstruction after surgical resection are proposed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
6/6. Ileal loop replacement and restoration of kidney function in extensive bilharziasis of the ureter.Ileal loop replacement is often the only possible treatment of extensive bilharziasis of the ureter. Experience with 5 such cases is presented and the special problems arising from the nature and extent of the lesion are discussed. In bilateral cases, attempts should be made to preserve as much renal tissue as possible. Non-functioning kidneys in 3 cases were not removed and a degree of function was restored following the relief of obstruction by also connecting these kidneys to the ileal loop.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
