A 39-year-old male presented with gross hematuria and left lower abdominal discomfort. Excretory urography showed a left ureteral stone and hydronephrosis. CT scans and magnetic resonance imaging showed a solid mass at the upper pole of the left kidney. Angiography revealed a hypervascular lesion at this area. The laboratory data showed a slightly decreased serum potassium level. In the endocrinological study, the serum deoxycorticosterone (DOC) level was markedly elevated. There was, however, no evidence of hypertension. The operation was performed on November 13, 1992. The tumor was almost separated from the left kidney, but an aberrant artery which divided from the renal artery and penetrated the renal parenchyma was found. Therefore, we had to carry out en bloc removal of the tumor together with the left kidney and the ureter which contained the ureteral stone. Pathological diagnosis was adrenocortical carcinoma. After the operation, hypokalemia and the serum concentration of DOC returned to normal range. Therefore, the tumor was diagnosed as DOC producing adrenocortical carcinoma. The patient was discharged 30 days after the operation with uneventful postoperative course. He received 2.5 g of op'-DDD a day. There was no evidence of distant metastasis or local recurrence 12 months after the operation. Nineteen cases of DOC producing adrenocortical tumor have been reported in the world literature. A case and a review of the literature are herein reported.

A 65-year old man, who had had resection of a right ureter tumor two years earlier, was hospitalized with complaints of lower abdominal discomfort and hematuria. Pathological diagnosis of the ureteral tumor was grade 3 transitional cell carcinoma. Computed tomography and magnetic resonance imaging demonstrated a large tumor in the retrovesical space and recurrence of transitional cell carcinoma was suggested. Total pelvic exenteration was performed and pathological diagnosis of the tumor was undifferentiated carcinoma simulating malignant lymphoma. Immunohistochemical examinations revealed no antigens specific for the lymphoid cells or epithelial cells on the specimen. This tumor consisting of undifferentiated carcinoma was considered to be recurrence of transitional cell carcinoma with the diffuse pattern simulating malignant lymphoma proposed by Zukerberg et al.

This study was applied on 9665 cases between January 1993 and October 1998. Of these, 6985 (72.3%) were urologic patients and 2680 (27.7%) were autopsy cases. The patients having urinary complaint investigated by urine analysis and kidney-ureter-bladder film (KUB), routinely. In all patients who have pathological urine, ultrasonography exam was done and in all patients who established an abnormality on ultrasonography, intravenous pyelography (IVP) was taken, also. We established the horseshoe kidney in 23 of patients (1/304) and in 6 of autopsy cases (1/447) with overall incidence 1/333. There were 21 male and 8 female with horseshoe kidney (male/female = 2.6/1). Abdominal discomfort with lower lumbar pain and Rovsing's sign were seen in 56.5% and in 65.2% of patients respectively. We concluded that horseshoe kidney incidence is almost the same as reported in the literature, although its clinical appearance is higher in our urologic patient population. In the urological out-patient evaluation, at least Rovsing's sign should be applied to all patients with lower lumbar pain with vague abdominal discomfort and an abdominal ultrasonographic exam should be applied, if this sign is positive.

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.

A 38-year-old woman with a duplicated right collecting system and a history of right upper-pole heminephrectomy was referred for persistent dysuria and right lower-quadrant abdominal discomfort. Imaging identified a remnant ureter and a ureterocele filled with what appeared to be a large homogenous stone. At cystoscopy, the ureterocele was incised with a holmium:YAG laser, releasing a large quantity of white milky fluid (milk of calcium). There was no evidence of any solid material. Endoscopic evaluation should be the first step in patients with stones in a ureteral stump because milk of calcium may be the etiology of what appears to be a large stone burden in an obstructed system.

Retroperitoneal fibrosis (RPF) is characterised by inflammatory fibrotic processes affecting the retroperitoneal structures. Its prevalence of 1 - 2/200,000 makes it a rare disease. To date, there are no guidelines for the diagnosis of or therapy for the disease. If untreated, the disease may be fatal. In 2006, the Department of Urology of the HELIOS Klinikum Wuppertal undertook to establish a nationwide patient registry, which would facilitate prospective therapy trials and the drafting of recommendations for diagnostic procedures. The pathogenesis of the disease is still unclear. Since some RPF-patients present with associated autoimmune diseases, autoimmune processes are suspected to play a role in causing the disease. The presence of autoantibodies and histological similarities with vasculitis support this hypothesis. Following initial general symptoms, patients display localised symptoms (flank pain, leg oedema, abdominal discomfort), caused by the displacing effect of the fibrotic plaques. Laboratory tests show elevated ESR and C-reactive protein and in some cases a moderate anaemia. Histological examinations should be undertaken to rule out the presence of malignant tumours. Radiological diagnostics (excretory urography, CT, MRI) show a retroperitoneal mass which blocks, compresses and displaces, completely or in part, the large vessels and the ureter. Initial therapy aims at restoring the function of the affected hollow organs through the application of (ureteric) stents, followed by immunosuppressive therapy. If drug therapy is unsuccessful, surgical procedures will follow to protect the ureter from compression. In some cases, ureteral replacement or an autotransplant of the kidney may be necessary. Life-long observation of the patients is necessary, as the disease may be chronic and relapsing. Interdisciplinary and nationwide cooperation is of crucial importance to further investigate this disease.

A 5-year-old domestic shorthair cat, that had undergone renal transplantation 3 months earlier, was evaluated after an acute episode of abdominal discomfort. Abdominal ultrasound revealed an enlarged renal allograft (5.5 cm; reference range, 3.2-4.2 cm) with pyelectasia (renal pelvis=3.7 mm; reference range, 1-2mm). Based on the ultrasonographic appearance of the allograft, primary rule-outs for the renomegaly included hypertrophy and allograft rejection. The ureter and urethra were dilated and a mild amount of abdominal effusion was noted. Thirty-six hours after admission, the cat became acutely hemodynamically unstable and was diagnosed with a hemoabdomen. Review of the original ultrasound revealed a peri-renal hematoma. During emergency laparotomy, ruptures in the cortex of the transplanted kidney were found to be the source of hemorrhage. Immediately following surgery, the cat experienced cardiorespiratory arrest, and resuscitation was not successful. Necropsy and histopathology revealed rupture of the renal allograft. This is the first reported case of renal allograft rupture in a cat, whereas allograft rupture has been reported in human renal transplant patients.
