We report on 3 patients who presented with an acute onset of abdominal pain, a palpable abdominal mass and a rapid decrease in hemoglobin. In 2 patients a spontaneously ruptured hypernephroma was found and the other patient had a squamous cell carcinoma of the ureter with bleeding into the tumor. Although in all 3 cases the tumors were at an advanced stage of development, the patients had been entirely free of urological symptoms until shortly before hospitalization. The importance of considering the possibility of spontaneous rupture of such a tumor in the evaluation of cases of an acute abdomen is stressed.

Extravasation of urine was seen in 24 intravenous pyelograms taken for renal colic during the year 1973-74. A number of the patients presented with an acute abdomen. Extravasation took place of retained urine under pressure in the renal pelvis with leakage either around the clayces, from a fissure in the pelvis or even around the ureter. Extravasations of this type are in general rabsorbed without trace. In 5 cases, operation was necessary to drain a purulent collection which had developed in association with the extravasated urine.

A case of spontaneous rupture of the ureter initially presented as left acute abdomen in a 71 year old woman is described. A review of the literature has disclosed that in all reported cases a process directly or indirectly leading to the rupture was identified. On the basis of the clinical evolution and the radiological investigations the Authors discuss the diagnosis and the pathogenesis of the observed ureteral rupture.

A case of primary right ureteral squamous cell carcinoma with intraperitoneal invasion was studied. The patient was a 38-year-old male with chief complaints of right lumbago and gross hematuria. He was admitted to our clinic suspected of having calculi. However, the radiogram was negative. As the patient was suffering from severe hypogastric pain, indicating acute abdomen, an investigative celiotomy was performed. The tumor that was subsequently revealed formed a mass engulfing the furcation of the right internal and external iliac arteries, ureter, ileum and sigmoid colon. As a radical resection was considered impossible, as much of the tumor as possible was excised and a colostomy was performed. After the operation, a regimen of polypharmacy, including bleomycin, was administered against the residual tumor. This therapy has proved to be remarkably effective. At present, the patient is under regular medical observation, and the postoperative course has been favorable.

A case of solitary ureteral metastasis from cervical cancer in a 36-year-old female is reported. On April 4, 1988, the patient visited the gynecological department of our hospital with abnormal genital bleeding. Colposcopy and cervical biopsy revealed invasive cervical cancer, and computerized tomography (CT) indicated right hydronephrosis. She was referred to the urological department for further examinations. Right retrograde pyelography (RP) however could not be performed. On April 13, 1988, the patient underwent laparotomy due to acute abdomen, which was proved to be caused by subileus. On exploration, a tumor was found in the lower one third section of the right ureter, whereupon a right nephroureterectomy was performed because primary ureteral tumor was suspected. The histology of the ureteral tumor revealed it to be a metastatic squamous cell carcinoma identical to that obtained from punch biopsy of the cervix. At that time, a hysterectomy could not be done because of invasive cervical cancer. Following the operation, radiation therapy was conducted for primary cervical cancer. At present, 7 months after the operation, the patient is alive with good performance status.

Critical injuries of the kidney have to be treated surgically immediately. Here also have to consider the same rules of the surgery that go with an acute abdomen. By slight and severe injuries to the kidneys there is adaequate time for a thorrow diagnostic work up, prior to eventual operative intervention. The extreme rare ureter lesions with the symptomatic of a peritonism due to an urinoma and a retroperitoneal haematoma have to be treated operatively at the earliest possible time. Injuries to the urine bladder have always to be treated operatively with a special urgency since letality increases rapidly after six hours after the injury. Lesions of the urethra have to be treated operatively early by eliminating haematoma and urine and exact anastomosis of urethra's stumps to avoid later complications through scar-building.

We report on an 8-year-old girl who presented clinically with an acute abdomen. Examination revealed a left hypoplastic kidney with its ureter draining into the lower segment of the vagina, which was closed by an imperforate hymen. Initially, we thought that pressure by the urometrocolpos on the right ureter caused right hydronephrosis. Subsequently, it was found that the right ureter followed a retroiliac course and was compressed by a U-shaped iliac artery loop at the ureteral crossing. The iliac artery extended to the level of the second lumbar vertebra.

A 57-year-old man, 6 years after discovery of a left ureteral tumor was admitted to our hospital complaining of severe left abdominal pain. With the diagnosis of acute abdomen, the patient was examined by computed tomography, which showed severe left hydronephrosis with renal rupture. Retrograde and antegrade pyelography showed the hydroureteronephrosis due to the tumor in the lower ureter, so left nephroureterectomy was performed. The ureteral tumor was diagnosed as transitional cell carcinoma, grade 3 and pT2. The present case is the 9th case of spontaneous renal rupture caused by renal pelvic and ureteral tumors in Japan.

A 60-year-old man was treated by extracorporeal shock wave lithotripsy (ESWL) for an impacted ureter stone. Two days after the procedure he developed an acute abdomen. On laparotomy, a small bowel perforation in the area of an adhesion to the abdominal wall was found. The adherent intestinal segment was located exactly in the range of the ESWL field, so that excluding further reasons the shockwave lithotripsy must be assumed to be causative.

A multicentre phase II trial was undertaken to evaluate the activity and toxicity of docetaxel plus cisplatin as first-line chemotherapy in patients with urothelial cancer. Thirty-eight patients with locally advanced or metastatic transitional-cell carcinoma of the bladder, renal pelvis or ureter received the combination of docetaxel 75 mg m(-2) and cisplatin 75 mg m(-2) on day 1 and repeated every 21 days, to a maximum of six cycles. The median delivered dose-intensity was 98% (range 79-102%) of the planned dose for both drugs. There were seven complete responses and 15 partial responses, for and overall response rate of 58% (95% CI, 41-74%). Responses were even seen in three patients with hepatic metastases. The median time to progression was 6.9 months, and the median overall survival was 10.4 months. Two patients who achieved CR status remain free of disease at 4 and 3 years respectively. Grade 3-4 granulocytopenia occurred in 27 patients, resulting in five episodes of febrile neutropenia. There was one toxic death in a patient with grade 4 granulocytopenia who developed acute abdomen. Grade 3-4 thrombocytopenia was rare (one patient). Other grade 3-4 toxicities observed were anaemia (three patients), vomiting (five patients), diarrhoea (four patients), peripheral neuropathy (two patients) and non-neutropenic infections (seven patients). Docetaxel plus cisplatin is an effective and well-tolerated regimen for the treatment of advanced urothelial cancer, and warrants further investigation.
