Renal leiomyoma is a rare benign tumor which has its origin in smooth muscle cells of different structures of the kidney. The clinical incidence of renal leiomyoma is much lower than the frequency described in large autopsy studies. Renal leiomyomas are mainly located in the renal capsula and pelvis or next to those structures. Clinical symptoms are nonspecific (e.g., flank pain or flank tumor) or completely absent, making most of the leiomyomas an incidental finding during routine diagnostics. A differential diagnosis between renal leiomyoma and renal cell carcinoma on the basis of medical imaging is extremely difficult. Therefore, laparotomy and nephrectomy are performed in most cases of suspected renal cell carcinoma. The definitive diagnosis of a leiomyoma is only possible after histological examination of the tumor. Due to the rising number of diagnoses resulting from improved medical imaging, renal leiomyomas are gaining more importance in the differential diagnosis of renal cell carcinoma, especially with respect to kidney-sparing surgery.

The diagnostic value of unenhanced helical computed tomography was investigated in a prospective study. In 53 patients (aged 35 to 82 years) with acute flank pain tomography was performed in addition to abdominal plain film and ultrasound examination. All 53 patients had a contraindication for intravenous administration of contrast medium. Ureteral calculi were either confirmed or excluded by retrograde ureteropyelography in 44 cases, in 9 patients by asservation of calculi and clinical follow-up. Helical computed tomography was able to precisely identify all of the 34 ureteral calculi, whereas abdominal plain films led to 6 false positive and 17 false negative findings. In 1 patient with retroperitoneal lymphoma (diagnosed by CT) false positive findings occurred. Unenhanced helical computed tomography reaches a distinctively increased diagnostic value (sensitivity 100%, specificity 95%, accuracy 97%) in the evaluation of acute flank pain as compared to conventional radiologic imaging and ultrasound. This non-invasive procedure is to be considered method of choice for patients with contraindications for the application of radiopaque material.

We present a case of spontaneous rupture of bilateral renal angiomyolipoma (AML) with tuberous sclerosis. A 46-year-old woman was admitted with sudden onset of severe left flank pain. She had been diagnosed to have bilateral AML with tuberous sclerosis 15 years earlier. Four years after the initial diagnosis, spontaneous rupture of right renal AML occurred and right renal embolization of the right renal artery was performed. The treatment for the left renal AML was not performed. Eleven years later in 2000, spontaneous rupture of contralateral renal AML occurred and left renal embolization of the left renal artery was performed. We evaluated the efficacy of selective arterial embolization in right AML and the change of the tumor size during a 10-year follow up after embolization. The right AML had decreased 86% in 11 years. Selective arterial embolization is an effective and safe treatment for AML. We evaluated the natural history of left AML and calculated the doubling time to be about 1,370 days for the first period of 4 years and about 2,075 days for the second period of 11 years. Although the growth change was very slow, we should observe the tumors carefully on computed tomography or ultrasound to prevent life-threatening hemorrhage.

We have a case of pelvic lipomatosis in a patient suffering from right flank pain and urinary syndrome. Before completing the diagnostic test, abdominal traumatism forced to perform a laparotomy of emergency. We found a great deal of retropubic mass with bladder rupture and thickened walls caused by perivesical fat. The anatomopathological diagnosis was pelvis lipomatosis. This is an unusual case of bladder rupture after slight traumatism.

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.

Although ureteral obstruction is rarely noted in patients with gastric cancer at an advanced stage or at autopsy, the condition caused by authentic ureteral metastasis of gastric cancer is extremely rare. We experienced a case of gastric cancer in a 51-year-old woman who showed bilateral ureteral metastasis. The patient initially complained of right flank pain, caused by right ureteral obstruction, and was referred to our hospital, where she underwent a right nephroureterectomy, with suspicion of primary ureteral neoplasm. Histopathological examination of the resected specimen showed that metastatic growth of adenocarcinoma in the ureteral wall had caused the obstruction, and the subsequent extensive search for the primary lesion revealed asymptomatic gastric cancer. Soon after the nephroureterectomy, the patient developed left hydronephrosis, possibly caused by left ureteral metastasis, and a left percutaneous nephrostomy was performed. She then received chemotherapeutic reagents. However, she finally developed peritoneal carcinomatosis, and died of the disease about 1 year after the onset of the disease. In this report, we also review true ureteral metastasis from the stomach, and discuss the clinicopathologic features.

A 72-year-old non-diabetic uremic woman underwent right nephrectomy for urolithiasis at the age of 50. Because pyuria, fever, chilliness and left flank pain developed during preparing for arteriovenous fistula, she was admitted to National Cheng Kung University Hospital. Renal cell carcinoma (RCC) complicated with emphysematous pyelonephritis (EPN) was diagnosed and immediately treated with antibiotics and CT-guided percutaneous catheter drainage. Cultures of pus and blood yielded Escherichia coli. She received left radical nephrectomy later for the control of persistent sepsis and removal of left renal tumor. The pathology of the tumor was composed of a glandular arrangement of granular cells with the occasional atypism, and renal parenchyma had been totally replaced by RCC. The non-tumor part of the kidney showed chronic pyelonephritis. Five months later, multiple metastases developed. We reported this first uremic case with EPN and RCC, but without diabetes mellitus and urinary tract obstruction. The gas formation may be due to large RCC, which caused impaired tissue perfusion and E. coli infection.

A 72-year-old woman developed severe flank pain associated with hemodynamic compromise immediately after a J-curve guidewire was inadvertently advanced into the right renal artery during cardiac catheterization. Contrast extravasation consistent with perforation of the main renal artery was seen on abdominal angiography. The perforation was successfully sealed using a premounted coronary stent that was covered with an autologous antecubital vein. Wide stent patency without aneurismal dilatation was confirmed on a 2-year follow-up renal angiogram.

We report on a 17-year-old white woman with multiple bilateral renal angiomyolipomas (AMLs) in the absence of tuberous sclerosis. Multiple hyperdense lesions were detected in both kidneys by sonography. A computed tomography (CT) scan confirmed mainly fatty tissue. Sparing as much functional tissue as possible, eight AMLs of the right kidney were resected. The largest removed tumour measured 7 x 4 x 2.4 cm. Renal function was completely preserved. An AML is a benign, generally unilateral renal tumour. Treatment is necessary in cases of flank pain, spontaneous bleeding, obstruction by tumour growth and tumours exceeding 4 cm in diameter. Patients who present are often symptomatic due to pain, retroperitoneal bleeding or haematuria. An AML occurs either sporadically or in association with tuberous sclerosis. Bilateral or unilateral multiple AMLs are rare.

A 48-year-old woman was referred to our hospital with high fever and left flank pain. She was diagnosed with diabetes mellitus (DM), and abdominal computed tomography (CT) revealed left perinephric abscess with much emphysema. She underwent drainage of the abscess by left flank incision after treatment with antibiotics and insulin. The pus culture revealed Escherichia coli. Immediately after drainage, the symptoms began to subside. At three months after drainage, abdominal CT revealed no emphysema around the left kidney. At 18 months after the discharge, left perinephric abscess was not seen and DM was well controlled with insulin.
