OBJECTIVES To reveal individual, institutional and regional factors affecting selection of minimally invasive nephroureterectomy in Japan. METHODS The Japanese Diagnosis Procedure Combination database was queried to retrieve cases of nephroureterectomy for pelvic or ureter malignancies carried out between 2007 and 2010. A multivariate logistic regression(More)
OBJECTIVE To assess clinical and mechanical risk factors of clinically significant renal haemorrhage after extracorporeal shock wave lithotripsy (ESWL). PATIENTS AND METHODS Patient data were extracted from the Diagnosis Procedure Combination (DPC) database from 6 months per each year, 2006-2008. The availability of lithotripters in each hospital was(More)
In 2010, the International Society of Geriatric Oncology (SIOG) developed treatment guidelines for men with prostate cancer who are older than 70 years old. In 2013, a new multidisciplinary SIOG working group was formed to update these recommendations. The consensus of the task force is that older men with prostate cancer should be managed according to(More)
A total of 828 patients with esophageal cancer were treated at the Second Department of Surgery of Tokai University in the 20-year period from 1975 to June 1994, including 45 patients over 80 years old. We reviewed these elderly patients to assess the optimum therapeutic approach for such individuals. In recent years, the number of elderly patients with(More)
UNLABELLED Study Type - Prognosis (outcome) Level of Evidence 2b. What's known on the subject? and What does the study add? Reportedly, Fournier's gangrene has a high mortality rate, ~7.5-40%, and experts recommend early surgical debridement. This study examines 379 patients and shows that an early intervention, i.e. within 2 hospital days could halve the(More)
PURPOSE To compare the perioperative outcomes and costs between open and laparoscopic nephroureterectomy for malignant diseases on a contemporary population-based level. PATIENTS AND METHODS Based on the Japanese Diagnosis Procedure Combination database for 2010 to 2012, we compared six end points of in-hospital mortality, intraoperative and postoperative(More)
PURPOSE In this study we used nationwide population based data to compare perioperative outcomes, including severe bladder injury, between monopolar and bipolar transurethral resection of bladder tumors. MATERIALS AND METHODS Data of patients with clinical T2 or less bladder cancer who underwent monopolar or bipolar transurethral bladder tumor resection(More)
PURPOSE We analyzed the impact of hospital volume and laser use on postoperative complications and in-hospital mortality in transurethral prostatic surgery. MATERIALS AND METHODS We evaluated data from 18,578 patients in 686 hospitals who underwent transurethral prostatic surgery between July and December, 2006 to 2008, using the Diagnosis Procedure(More)
OBJECTIVE To investigate survival of hormone-naïve prostate cancer patients diagnosed with prostate-specific antigen ≥500 ng/ml, stratified according to the prostate-specific antigen level and type of therapy. METHODS Data of prostate cancer patients with prostate-specific antigen ≥500 ng/ml diagnosed between 2001 and 2003 and receiving primary androgen(More)
PURPOSE Genes of androgen and estrogen signaling cells and stem cell-like cells play crucial roles in prostate cancer. This study aimed to predict clinical failure by identifying these prostate cancer-related genes. EXPERIMENTAL DESIGN We developed models to predict clinical failure using biopsy samples from a training set of 46 and an independent(More)
