This is a report of a low-grade ureteral carcinoma presenting as a pelvic mass in a postmenopausal woman with a prolonged history of lower back pain. A right complex adnexal mass and right hydroureter and hydronephrosis in an atrophic nonfunctioning right kidney was found during evaluation for the back pain. Operative evaluation revealed a normal uterus and ovaries; however, a 2 x 3-cm mass in the right ureter was found at the level of the uterine arteries. A total abdominal hysterectomy, bilateral salpingo-oophorectomy, and right nephroureterectomy were performed with pathology returning grade I papillary transitional cell carcinoma of the ureter.

We experienced three cases of right hydronephrosis, which were later diagnosed to have been caused by gastric cancer (Borrmann type IV). The patients were 25-, 38-, and 50-year-old women who complained of right back pain. Ultrasound sonography revealed right hydronephrosis in all three cases. We conducted drip infusion pyelography, computed tomographic scan and retrograde pyelography, but there were no signs of urinary stones or tumors, except for the presence of right ureteral stenosis. Since the patients had upper abdominal discomfort, they underwent gastrofiberscopy, which revealed scirrhous gastric cancer. We suspected that the right ureteral stenosis was caused by metastasis of gastric cancer. After a double J catheter was indwelt at the right ureter, combination chemotherapy of methetrexate + 5-fluorouracil was conducted. The right hydronephrosis diminished and all three patients became catheter-free.

We report here the first case of localized amyloidosis of the ureter and bladder to be treated effectively by occlusive dressing technique therapy using dimethyl sulfoxide. The patient was a 48-year-old woman whose chief complaint was macrohematuria and right back pain. Ultrasound sonography demonstrated right hydronephrosis and an intravesical mass in the region of the right ureteral orifice. Retrograde pyelography revealed severe stricture of the right lower ureter. Cystoscopy demonstrated a yellow submucosal tumor around the right ureteral orifice. We suspected urinary tract amyloidosis, and transurethral biopsy and resection of the intravesical mass were performed under right ureteral stenting. Histopathological diagnosis was amyloidosis. There was no evidence of systemic amyloidosis. To treat residual amyloidosis of the ureter and bladder, we performed occlusive dressing technique therapy using dimethyl sulfoxide every day. After 6 months of therapy, the right hydronephrosis disappeared, and there was no evidence of a recurrence of amyloidosis. We concluded that this therapy was very effective and safe for urinary tract amyloidosis.

The authors present a review of the literature on inflammatory abdominal aortic aneurysms. These aneurysms represent from 3 to 10% of all abdominal aortic aneurysms. Progress has occurred in the technical approach to these aneurysms, and operative morbidity and mortality have been remarkably reduced. However, the pathogenesis remains poorly understood. Early reports have considered the inflammatory aneurysm as a distinct clinical and pathological entity, whereas recent evidences suggest a common etiopathogenetic mechanism for both atherosclerotic and inflammatory aneurysms. Finally, genetic and environmental factors, such as tobacco use, may predispose certain persons to the development of non-inflammatory aneurysms and others to a wide spectrum of inflammatory reactions until inflammatory aneurysms development. The most common clinical features of these aneurysms are represented by symptoms, such as abdominal or back pain, obstructive uropathy and by an elevated erythrocyte sedimentation rate. Computed tomography (CT) allows a specific diagnosis by the typical image of soft tissue surrounding the aortic wall enhancing with contrast administration. Ultrasonography is less sensitive whereas nuclear magnetic resonance (RNM) is a promising technique. Excretory urography may suggest the diagnosis by demonstration of ureter entrapment. Surgical therapy, by a technique of limited dissection represents the definitive treatment. Evolution of fibrosis after surgery is still debated because some studies have reported complete regression of inflammation and other partial regression or persistence of fibrotic process. At present, endovascular treatment of these aneurysms is occasionally reported, although preliminary results appear satisfactory.

Retroperitoneal fibrosis (Ormond's disease) is rare chronic inflammatory process, that can occur at any age. It is characterised by development of periaortic fibrous mass leading to progressive obstruction of vessels around the abdominal aorta and ureters. In the one third of cases we can find the causes of disease. There are ergotamine abuse, radiation, retroperitoneal surgery or hemorrhage, urine extravasation and response to different cancers. The other cases are idiopathic disease. We report a case of prostate cancer with unique course. The first manifestations of disease were diffuse peritoneal fibrosis and ureteral obstruction leading to bilateral hydronephrosis. Clinical course and histopathology showed idiopathic Ormond's fibrosis. Patient received oral immunosuppressive treatment (prednisolone 1 mg/kg/day + azathioprine 1 mg/kg/day), followed by intravenous methylprednisolone puls (2 g). Treatment also consisted of DJ-stent placement on the left side. On the right side we were unable to overcome the obstruction of ureter. Because of persistent renal failure, thrombocytopenia, DIC and progressive lower back pain we did control MR and CT scan. The CT scans showed multiple osteolytic bone metastases in vertebral column (the sizes of them were between a few millimetres and 1.5 centimetre). Patient died due to renal failure and haemorrhagic diathesis in the course of disseminated cancer of unknown origin. The postmortem examination revealed diffuse peritoneal infiltration surrounding the ureters, intramural ventricular metastases, pulmonary metastases and vertebral metastases. The prostate was only slightly enlarged. Histological and immunohistochemical examinations of prostate showed primary low-differentiated prostate carcinoma (CK/+/, PAP/+/, PSA/+/). Peritoneal, ventricular and bone infiltrations also were metastases from low-differentiated carcinoma of prostate origin (CK/+/, PAP/+/, PSA/-/).

A 66-year-old man presented at our hospital with left back pain. Intravenous pyelography, computerized tomography and magnetic resonance imaging revealed ureteral tumors of the complete left double renal pelvis and the ureter. An endoscopic examination disclosed a papillary tumor from the left ureteral orifice of the lower pole of the kidney. A transurethral resection of the tumor was done, and the pathological features revealed transitional cell carcinoma (PTa, grade 2). A left nephroureterectomy and a partial cystectomy were also carried out; macroscopic examinations showed a non-papillary tumor on the middle portion of the left ureter originating from the upper pole of the kidney. Microscopic examinations revealed transitional cell carcinoma (PT3, grade 3, PL1, PV1). Adjuvant chemotherapy (M-VAC) was administered but discontinued because of severe side effects. Dispite recurrence with retro-peritoneal lymph node metastasis, the patient is alive and again undergoing M-VAC chemotherapy 22 months after the initial surgery. However, the evaluation of the chemotherapy was "no change".

A case is described of a 47-year-old man with achondroplasia who presented with lower back pain radiating to his left loin. An intravenous urogram (IVU) showed hydronephrosis on the left side and a dilated left ureter passing down into the left inguinal region. A CT scan confirmed a left inguinal hernia containing the left ureter causing ureteric obstruction. The hernia was repaired using the Lichtenstein technique with the ureter replaced retroperitoneally. A postoperative IVU showed recovery in renal function but with a persistently dilated left ureter that was not obstructed. A review of the literature regarding inguinal herniation involving the ureter is presented.

We report a case of primary appendiceal cancer that metastasized to the ureter. The patient was a 51-year-old woman who complained of persistent left back pain and right lower abdominal pain. After a detailed examination she was diagnosed to have cancer of the appendix, multiple liver metastases, and left hydronephrosis. Since an obstruction of the ileocecum was obvious, she underwent an ileocecal resection and a resection of the spindle-shaped tumor invading the left ureter. Lymph node metastases were found at the root of the superior mesenteric artery. The spindle-shaped tumor was considered to be due to invasion of the appendiceal cancer to the left ureter. The patient died 5 months postoperatively.

A 75-year-old hypertensive woman was referred with ultrasound findings of a 40 x 35 mm semi-solid right adnexal mass and right hydroureteronephrosis. She complained of headache and right-sided back pain. Computed tomography demonstrated a cystic adnexal mass that did not appear to originate from the right ovary and grade 2 hydroureteronephrosis. Magnetic resonance imaging indicated that the mass originated from the right ovary. Tumor markers were in the normal range. Exploratory laparotomy was performed to determine the origin of the lesion, and revealed a retroperitoneal mass obstructing the right ureter. The mass was completely removed and and the histopathologic diagnosis was paraganglioma.

We previously reported a case of bilateral ureteral stenosis accompanied by systemic lupus erythematosus, which was successfully managed by total ureteral reconstruction using a segment of the ileum. Herein, we describe an unusual complication in the same patient, which we experienced 5 years after the ileal-ureteral substitution. Left-sided back pain repeated together with transient obstruction of the ileal ureter interposed between the right and left renal pelvis. Consequently, exploratory laparotomy revealed that left colic vessels oppressed and caused obstruction, and the obstructed ileal ureter was released by reconstitution of these vessels instead of re-anastomosis of the ileal ureter. Left hydronephrosis and related back pain disappeared postoperatively. The number of patients with an indication of ileal-ureteral substitution is increasing for various disorders, and thus, the present report gives additional suggestions for the follow up of patients with ileal ureter.
