A 47-year-old female was admitted to our clinic with the suspicion of ureteral foreign body. She had undergone acupuncture for left lumbago twelve years earlier. Plain X-ray film revealed a linear shadow and calcified shadows laterally to left third lumber vertebra. Computed tomographic scan and pyelogram showed them located in the left ureter. Left ureterolithotomy was performed successfully. The removed stone was accompanied by an acupuncture needle. Including our case, twelve cases of foreign bodies as a complication of acupuncture in the upper urinary tract reported in the Japanese literature were reviewed.

The increasing use of laparoscopy as a therapeutic method mandates a reappraisal of the risks involved. Complications frequently described include injuries to the large and small bowels, bladder, and blood vessels. The world literature reports only eight cases of ureteral injury at laparoscopy. In this report, we present five additional cases of ureteral injury occurring at laparoscopy, in addition to a summary of those previously reported. Patients tend to present in the early postoperative period (48-72 hours) with low back pain, abdominal pain, leukocytosis, and peritonitis. The diagnosis should be made by intravenous pyelography; if possible, the injury should be stented by either the retrograde or percutaneous route. The injuries, except for one apparent trocar injury, involved the use of electrocoagulation, both unipolar and bipolar. The injuries occurred most commonly near the uterosacral ligaments. In 38% (five of 13) of the cases, the laparoscopy was performed for treatment of endometriosis. Three of the 13 patients eventually lost renal function of the affected side; two of these underwent a nephrectomy. Because visualization of the ureter near the cervix at the time of laparoscopy is difficult, especially in the presence of disease, laparoscopic procedures in this area must be carried out with caution.

We report a case of metastatic ureteral tumor resulting from gastric cancer in a 56-year-old female. She had undergone distal gastrectomy for gastric cancer in our hospital 3 years earlier, on the histological diagnosis of poorly differentiated adenocarcinoma with absolute curative resection. In March, 1987, she visited our hospital complaining of microscopic hematuria and lumbago. Intravenous pyelography and left retrograde pyelography revealed the stenotic change of the left ureter and hydronephrosis. Endoscopic ureteral biopsy was performed, and the histological diagnosis was an inflammatory change of the ureter. But the hydronephrosis increased, so partial ureterectomy was performed. The histological examination confirmed adenocarcinoma in the left ureter resulting from gastric cancer. From the 340th postoperative day, she complained of general fatigue and vomiting, and gastroscopy revealed recurrent gastric cancer.

The patient was a 63-year-old women who visited our hospital with the chief complaints of swelling, chills, fever and right lumbago. Fifteen years ago, she received surgical exploration for right renal stones at another department of urology. A large, soft and round kidney was palpable from the right upper quadrant of abdomen to the right lower abdomen. The parenchyma of the right kidney was thinned and inside the kidney there was a huge amount of yellowish mucin. The histological diagnosis was mucin-producing cyst-adenoma (borderline malignancy) of the renal pelvis and ureter. Mucin-producing cystadenoma of the renal pelvis and ureter origin was very rare, and only 4 similar cases to our patient were so far reported.

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 right ureteral obstruction secondary to right common iliac aneurysm presenting as right hydronephrosis is reported and the literature is reviewed. A 66-year-old man was admitted to our hospital with lower abdominal pain and was treated by bypass operation with artificial vessel and uretero-ureterostomy of right ureter under the diagnosis of right ureteral stenosis secondary to right iliac aneurysm. Histological examination showed arteriosclerotic aneurysm and a fibrillary inflammatory change in peri-ureteral tissue without any hemosiderin-laden macrophages. Intravenous pyelography showed improvement of right hydronephrosis 45 days after operation. To date 11 cases including our case have been reported in Japan, 10 in males and the other in a female. Initial symptoms were either lumbago or an abdominal mass with palpitation in many cases. The treatment was by resection of aneurysm with bypass grafting or ureterolysis.

A case of ureteral endometriosis is reported A 42-year-old woman visited our clinic on December 3, 1985, with the complaint of right lumbago. Intravenous pyelography showed right hydronephrosis and retrograde pyelography revealed ureteral stenosis at 11 cm from right ureteral orifice and 2 cm long. Primary right ureter tumor was suspected. The operation was performed on January 16, 1986 and revealed periureteral mass. The mass was removed with ureter and ureteroureterostomy was performed. The pathological diagnosis was extrinsic ureteral endometriosis. Ureteral endometriosis has rarely been described and only 17 cases have been reported previously in Japan.

We report a case of retroperitoneal fibrosis. A 75-year-old man complained of edema of bilateral lower limbs and lumbago. Blood urea nitrogen and serum creatinine were increased. Renal function was improved after he had bilateral percutaneous nephrostomies. Antegrade pyelography showed bilateral hydronephrosis, left ureteral obstruction and medial deviation with narrowing of the right ureter. CT revealed a soft tissue density surrounding the aorta, inferior vena cava and bilateral ureters in the retroperitoneal space. Inferior venocavagraphy displayed stenosis. Bilateral ureterolysis combined with omental sleeve plasty was performed. Post-operatively, the clinical course has continued to be good.

We report a case of nephrogenic adenoma in the left ureter. The patient presented with lumbago on the left side. A small calculus was incarcerated in the left ureter 4 cm. from the ureteropelvic junction and an adenoma, which resembled histologically the renal tubules, was observed in the ureter. A search of the world medical literature revealed 58 cases of nephrogenic adenoma, although only 1 case in the ureter has been reported previously.

Case-reports of 85 patients with upper urinary tract tumors were reviewed. Mainly affected were males (87% of cases), particularly over 60 years of age, the principal presenting sign being hematuria. Other signs such as renal colic, lumbago or infections were observed more rarely. The renal pelvis was affected in 52 of the 85 patients (two of these were bilateral), multiple tumor foci being present in only 6 cases. Most tumors were epitheliomas (62 papillary and 13 non-papillary), with 52 of these at the superficial stage (0 or A), 21 at stage B 1 and 5 at stage B II or C. Based on Broders' classification, 48 were grade II and 16 grade III tumors. Prognosis was routinely poor in 5 patients with a stage B or C tumor and lymph node extension. Diagnosis is by intravenous urography, although retrograde ureteropyelography has its place, with increasing interest being given to ultrasound and computed tomography examinations combined with routine cystoscopy. If no particular contraindications exist, the preferred treatment is a total one-stage nephro-ureterectomy without curettage (52 cases), although curettage was performed at the same time in 9 other patients. Conservative surgery has only a limited application: 6 patients had segmental resections of the ureter and 2 patients underwent tumorectomy. Postoperative mortality was particularly loco: 4 patients (4,7%), mainly from vascular or respiratory diseases. (4,7%), mainly from vascular or respiratory diseases. Bone (5 cases), pulmonary (3 cases) and medullary (1 case) metastases represented the main cause of death during the year following surgery, all these patients having infiltrating tumors.(ABSTRACT TRUNCATED AT 250 WORDS)
