A rare case of obstruction of the pelvic segment of the ureter by an isolated focus of primary amyloidosis is described. The operation consisted of resection of the constricted segment of the ureter and end-to-end anastomosis, with very good early and late results. The differential diagnosis and therapy of this type of ureteral obstruction are discussed.

It is reported on a localised primary amyolidosis of the urinary bladder with a progressing course. In contrast to the prevailing observations of other authors during two years an increasing bilateral urinary stasis developed so that finally after an at first unilateral nephrostomy due to an infected retention kidney the bilateral ureter-intestine-anastomosis became necessary. Apart from a short description of the amyloidosis from the general and especially urologi-al point of view it is particularly referred to diagnostic difficulties, since the various forms of amyloidosis have a different prognosis and demand a therapy.

A 61-year old woman with 7 years' history of pain, infections and haematuria developed right ureter stenosis which was suspected of being a tumour. Microscopic examination of the ureter with stenosis showed primary amyloidosis. Although primary amyloidosis of the ureter is rare, it should be included in the differential diagnosis of ureter malignancy.

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 advanced stages, the three most common inflammatory bowel diseases - colonic diverticulitis, Crohn's disease and ulcerative colitis - cause, in some 10% of cases, secondary urological pathology involving either bladder or ureter. Colovesical fistula is found more frequently in diverticulitis and less often in Crohn's disease, which penetrates predominantly from the ileum into the bladder. On the other hand, if uretic stenosis develops it will be caused on the right side by Crohn's disease and on the left by ulcerative colitis. Vesico-intestinal fistulae will close without sequelae after resection of the diseased bowel segment. On the other hand, retroperitoneal ureteric stenosis - despite bowel resection and ureterolysis - will often require nephrectomy if operation is not carried out early enough. Frequent re-checks with infusion excretory urography will help to prevent this. Nephrolithiasis, amyloidosis and contracted bladder are other, though less common, complications of chronic inflammatory diseases of the bowel.

The three most common inflammatory diseases of the bowel, colonic diverticulitis, regional enteritis and ulcerative colitis, involve the bladder or ureter in the advanced stage in about 10%. The colovesical fistula is found more frequently with diverticulitis and less often with regional enteritis, which penetrates predominantly from the ileum into the bladder. On the other hand, if an ureteric stenosis develops, it will be caused on the right side mainly by regional enteritis and on the other side by ulcerative colitis. The vesicointestinal fistulae will close without sequelae after resection of the involved bowel segment. However, the ureteric stenosis will often be followed by nephrectomy despite bowel resection and ureterolysis, if the operation is not undertaken early enough. Frequent rechecks with infusion urography should help to prevent this. Nephrolithiasis, amyloidosis, and a contracted bladder are futher, yet less common complications of chronic inflammatory disease of the bowel.

Primary amyloidosis is seen in the absence of predisposing disease. It may affect most organs in the body, including the collecting system of the urinary tract. Submucosal calcifications have been described in the renal pelvis and may be pathognomonic for primary amyloidosis of the renal pelvis. We have been able to demonstrate similar submucosal calcifications in the ureter and bladder. The differential diagnosis of submucosal calcification of the distal ureter and bladder must include bilharziasis and tuberculosis. With the recognition of submucosal calcifications, diagnosis of the underlying disease may be readily made. An illustrative case is presented.

A case of localized amyloidosis of the distal ureter in a 51-year-old man is described. Pertinent features of previously reported cases are described, and the difficulty of distinguishing this entity from primary carcinoma of the ureter is discussed.

A case of primary localized amyloidosis of the ureter associated with osseous metaplasia, presenting as a calcification on computerized tomography, is reported. We believe this is the second such case to be reported in the world literature. The previous 34 cases of primary amyloidosis of the ureter are reviewed and the clinical presentations and treatments discussed. The difficulties of distinguishing the condition from transitional cell carcinoma of the ureter is emphasized. Surgical treatment should be conservative, if possible.

A 58-year-old woman was introduced to our department complaining of lower abdominal pain and macrohematuria in March, 1978. Intravenous pyelography revealed stenosis and a ureteral stone on the right distal ureter. In May, 1983, she visited our department again. Endoscopically, bleeding from the right ureteral orifice was observed. Retrograde pyelography demonstrated the right hydronephrosis and irregular margin of the right lower ureter. However, the urine cytology was negative, and CT scan and ureteroscopy showed no tumorous lesion on the portion. On 7 August, 1989, partial ureterectomy and end to end anastomosis was performed. Histopathological examination by H-E and Congo red stain proved amyloid deposition. Postoperative course was uneventful. A total of 40 cases of amyloidosis of the ureter in the world are reviewed.
