Localized amyloidosis of the ureter is a relatively rare condition. We report a case of primary localized ureteral amyloidosis. A 66-year-old man was referred to our hospital complaining of right flank pain and gross hematuria. From the right hydronephrosis and irregular margin of the right lower ureter seen on the anterograde pyelography, we could not rule out a right ureteral malignancy. Total nephroureterectomy was performed and histologic examination showed ureteral amyloidosis. Amyloid was classified immunohistochemically as Alambda type. After all examinations for secondary or systemic amyloidosis were negative, primary localized amyloidosis of the ureter was confirmed.

A 66-year-old man presented with right flank pain and macroscopic hematuria. Abdominal radiographs and computed tomography revealed a right pyelocalyceal diverticulum with milk of calcium and a soft tissue mass inside it. Other examinations, including positive urine cytology and negative random bladder biopsies, suggested a malignant tumor of the pyelocalyceal diverticulum. The patient underwent right nephroureterectomy. Histopathological examination revealed grade 3 transitional cell carcinoma. This is the first case of transitional cell carcinoma and milk of calcium coexisting in the same pyelocalyceal diverticulum.

A case of spontaneous peripelvic extravasation with ileocecal cancer is reported. A 60-year-old man with right flank pain was referred to our department. Dripinfusion pyelography showed right peripelvic extravasation. Neither computed tomography (CT) nor retrograde pyelography revealed any ureteral stones or tumors. Urinary cytology was negative. One month later, right retrograde pyelography demonstrated the filling defect in the right ureter, but no stones, ureteral tumors or other tumors related to the ureter were detected by CT. An exploratory laparotomy was done. We found an ileocecal tumor invading to the right ureter and disseminated to the peritoneum. Histological diagnosis was mucinous carcinoma.

To evaluate urinary NMP22 dosage as a marker of urothelial tumours, we have selected a group of 90 patients (85 males and 5 females, mean age 66 years) with clinical suspicion of transitional cell carcinoma (TCC), with microscopic or macroscopic hematuria, flank pain, urographic abnormalities and dysuria. All the patients have been evaluated by urinary cytology, renal and bladder ultrasound, cystoscopy. When a bladder tumour has been detected, bladder biopsies and, when required, I.V.P., CT or retrograde pyelography have been performed. A urine sample has been collected between midnight and noon; all samples from patients who were undergoing invasive procedures such as cystoscopy, were collected before or at least 5 days after the procedure. The test has been performed according to ELISA NMP22 (Matritech) technique; the test is specific for the nuclear matrix protein/nuclear mitotic apparatus protein expressed by cancer cells. When performing the test, 30 patients presented macroscopic hematuria. 22 patients resulted to have benign urinary tract conditions, 65 patients had TCC and 3 patients had a final evaluation suspicious for TCC. The NMP22 values were respectively 7.1 +/- 4.7 U/ml, 21.9 +/- 21.0 U/ml and 16 +/- 8.0 U/ml. From our study the sensitivity of the test is 67% (with a threshold value of 10 U/ml) and 55% (with a threshold value of 20 U/ml), while the urinary cytology resulted to have a sensitivity of 26% (p < 0.05). The sensitivity of the test in relation to staging was as follow: Tis 66% with a mean NMP22 value of 23.3 U/ml, Ta 26% with a mean NMP22 value of 13.2 U/ml, T1 100% with a mean NMP22 value of 40 U/ml, T2 73% with a mean NMP22 value of 36.4 U/ml. The specificity of the test was 100% with a threshold value of 20 U/ml. When considering a threshold value of 10 U/ml, the NMP22 test has a sensitivity higher than cytology, especially in low stage TCC. Macroscopic hematuria does not affect its sensitivity; the diagnostic efficacy of the test is not increased by the association of urinary cytology. It has an important role in the diagnosis of residual disease after TURB and in the follow-up evaluation of bladder cancer patients, since its dosage is not influenced by inflammatory conditions of the mucosa. We believe therefore that NMP22 is useful in clinical practice.

Although a transhiatal bilateral splanchnicotomy (TBS) has many advantages, it has not been widely employed as an effective minimal invasive therapy for intractable supramesenteric pain. Furthermore, the effects of TBS have not yet been clearly evaluated. Between 1995 and 1997, TBS was performed on 11 patients with intractable epigastric and/or flank pain due to unresectable pancreatic cancer, chronic pancreatitis, or an unknown cause. The effect of TBS on the pain was evaluated using a novel simple pain score and pain reduction percentage scaled on the basis of the medication and the judgments by patients themselves, respectively. The detection and cutting of the bilateral great splanchnic nerves were easily performed in all of the patients using common flexible chondrocostal retractors. The evaluation of the TBS effect using the pain score clearly demonstrated the early and late mean postoperative pain score (1.1 +/- 0.9 and 1.4 +/- 1.2: mean +/- SD) to be significantly (P = 0.0002 and P = 0.002, respectively) lower than the preoperative pain score (3.5 +/- 0.7). Furthermore, the mean postoperative pain reduction percentage (85% +/- 13%) evaluated by those patients was also significantly different (P < 0.0001). The present study showed no significant complications for TBS, except for minor complications such as the transient fall of blood pressure and reparable pleural damage. Interestingly, a long-term follow-up revealed that no complications related to the splanchnicotomy were observed. These results indicate that TBS is a useful treatment for patients with intractable supramesenteric pain caused by cancer as well as benign diseases.

A 39-year-old woman arrived to the emergency department complaining of a constant, progressive, left flank pain, with no beneficial effect from spasmolytic and nonsteroidal antiinflammatory drugs. Two years before, she suffered another episode of right flank pain and stranguria, but instrumental examinations (ultrasonography, urography) remained negative. Besides a mild tenderness in the left flank, physical examination was normal. Blood chemistry panel showed leukocytosis (17.2 x 10(3) mL, neutrophils 82.8%) and a slight increase of serum lactate dehydrogenase (LDH) (543 U/L versus 230 to 460 U/L). Urinanalysis showed a slight hemoglobinuria (0.5 mg/dL), and sediment contained some red cells and leukocytes. Diagnostic examinations (ultrasonography, computed tomography) showed a left renal nonhomogeneous space-occupying lesion, orientative for renal malignancy. She was transferred to the urology department and operated. Both intraoperatory and histological diagnosis was ischemic infarction and, after exclusion of all possible underlying causes, final diagnosis was idiopathic renal infarction. Diagnostic procedures and literature reports are discussed.

Inappropriate antidiuretic hormone secretion (SIADH) may occur in a variety of diseases, including malignancies, and can be induced by drugs. We report a case of SIADH associated with prostatic carcinoma. A 50-year-old man was admitted to hospital with severe flank pain and weight loss. The diagnosis of SIADH syndrome and prostatic carcinoma was established, and hormonal therapy was instituted. However, the patient died in a month without any response to therapy. We conclude that prostatic carcinoma may cause SIADH and should therefore be considered in the differential diagnosis.

Penile metastasis is rare. It occurs in the advanced stage of genitourinary cancer, with many other metastases in various organs. All 7 patients with penile metastasis of renal cell cancer, reported in the Japanese literature, died within a year. Our case was not the exception. A 69-year-old male presented with right flank pain and penile induration. Right renal cancer with liver invasion and multiple pulmonary metastases were found. Microscopic examination revealed a sarcomatous pattern. He died 4 months later.

Renal primitive neuroectodermal tumor (PNET) is a rare and highly malignant neoplasm of the kidney. We report the case of a 17-year-old girl with renal PNET that was complicated by Budd-Chiari syndrome. She was admitted due to abrupt left flank pain and gross hematuria. Abdominal sonography and computerized tomography (CT) disclosed a large hemorrhagic left renal mass and thrombus in the inferior vena cava (IVC). Left radical nephrectomy was performed and renal PNET with tumor rupture and tumor invasion into the IVC was diagnosed based on operative findings and histologic features. Tumor cells were positive for neuronspecific enolase, chromogranin-A, and vimentin but negative for cytokeratin, leukocyte common antigen, CD3, and CD20. The thrombus in the IVC extended into the right atrium and caused obstruction of the right and middle hepatic venous outflow, which was evident on follow-up CT scan 5 months later. The patient died due to hepatic failure and progressive cardiovascular compromise 6 months after surgery. This case demonstrates that renal PNET can be life threatening when the tumor thrombus extends into the IVC and causes hepatic outflow obstruction.

Peptic ulcers complicated by penetration into the surrounding tissue and presenting as an intra-abdominal mass simulating a malignancy are uncommon. We report on a case of a 56-yr-old physician with a 40-yr history of peptic disease. Due to recent and transitory right flank pain, an ultrasound then a computed tomography scan demonstrated a 4-cm retropancreatic mass. A fine-needle aspiration biopsy (FNAB) of the mass showed an acute and chronic inflammatory exudate. After a course of medical treatment for peptic ulcer disease and 5 mo after the biopsy, the mass remarkably decreased in size. In view of the clinical and FNAB findings, the lesion likely developed as a result of penetration of the duodenal ulcer into the retropancreatic space. Awareness of this uncommon complication of peptic gastroduodenal ulcer disease is helpful in the diagnosis of this benign lesion. A failure in making a firm diagnosis by considering the aspirate material as nonrepresentative may lead to an unnecessary repeat biopsy or an invasive procedure.
