The authors present two cases of primary synovial sarcoma of the kidney. Both patients had a tumor mass in the kidney with vascular invasion of the inferior vena cava and right atrium of the heart in case no. 1. In case no. 2 retroperitoneal lymph node metastasis and multiple metastases to both lungs were observed. Radical nephrectomies were performed in(More)
We reported previously that 18F-2-fluoro-2-deoxyglucose positron emission tomography/ computed tomography (FDG PET/CT) had potential for evaluating early response to treatment by tyrosine kinase inhibitors (TKIs) in advanced renal cell carcinoma (RCC). This time we investigated the relation of the early assessment by FDG PET/CT to long-term prognosis with(More)
BACKGROUND Several studies have reported that the chimeric monoclonal antibody to tumor necrosis factor (TNF)-alpha (Infliximab) is extremely valuable in the treatment of Crohn's disease. The aim of this study was to clarify the efficacy of this treatment in Japanese patients with Crohn's disease. METHODS A 12-week multicenter, open trial of Infliximab(More)
Although patients with prostate cancer with metastatic lesions initially respond to androgen ablation therapy, most patients ultimately develop a hormone-refractory state. Effective treatment for men with hormone-refractory prostate cancer (HRPC) has not been established. We performed a clinical study of docetaxel in HRPC patients, and evaluated its(More)
INTRODUCTION The objective of the present study was to evaluate the safety of retroperitoneoscopic nephrectomy (RN) in obese Japanese patients. PATIENTS AND METHODS We retrospectively reviewed 190 consecutive RN procedures performed from May 2002 to May 2006. We divided patients into an obese group (BMI >or=25, n = 54) and a normal group (BMI <24.9, n =(More)
OBJECTIVES To describe the development of a patient-specific simulator for laparoscopic renal surgery. METHODS Image data of each patient scheduled to undergo laparoscopic renal surgery are captured by the simulator, enabling each patient's organs to be reproduced. The surgeon can carry out a preoperative "rehearsal" of the operation by using a simulator(More)
There is no reliable biomarker for predicting the prognosis of patients who undergo radical cystectomy for bladder cancer. Recent studies have shown that the neutrophil-to-lymphocyte ratio (NLR) could function as a useful prognostic factor in several types of malignancies. This study aimed to assess the usefulness of NLR in bladder cancer. A total of 74(More)
Dialysis patients have a tendency to bleed, and clinicians sometimes encounter cases with a significant amount of spontaneous hemorrhage. We herein report two cases of spontaneous renal hemorrhage in hemodialysis patients. CASE 1: A 70-year-old male who had received hemodialysis for 8 years presented with right abdominal pain. He had a history of renal(More)
In this era of molecular targeting therapy when various systematic treatments can be selected, prognostic biomarkers are required for the purpose of risk-directed therapy selection. Numerous reports of various malignancies have revealed that 18-Fluoro-2-deoxy-D-glucose (18F-FDG) accumulation, as evaluated by positron emission tomography, can be used to(More)
OBJECTIVES Laparoscopic adrenalectomy has become an effective option for aldosteronoma. We evaluated the retroperitoneal approach with regard to safety, efficacy, invasiveness and cost-benefit ratio in patients with primary aldosteronism. METHODS Between July 1999 and June 2005, we carried out a total of 195 retroperitoneoscopic adrenalectomies (RA) in(More)
