PURPOSE We determined whether diagnostic ureteroscopy for upper urinary tract cancer affects intravesical recurrence and cancer specific mortality. MATERIALS AND METHODS In a retrospective, multi-institutional study we evaluated 208 patients undergoing nephroureterectomy for upper urinary tract cancer who had no perioperative systemic chemotherapy,(More)
From March 1989 to December 1992, we encountered 25 kidneys in 21 patients with a suspicious ureteropelvic junction (UPJ) obstruction detected only on prenatal ultrasound. In all these patients other urological abnormalities were excluded by voiding cystourethrography and other radiological findings. Diuretic renography (DR) was initially performed at an(More)
BACKGROUND Hypospadias is one of the most common congenital anomalies in the world. Recently, increases in the prevalence of hypospadias have been reported in various countries including Japan. In this study, we examined whether the prevalence of hypospadias in Hokkaido, Japan, increased or not, using standardized diagnostic criteria. We also investigated(More)
PURPOSE We determined prognostic factors associated with prolonged survival after metastasectomy for urothelial carcinoma. MATERIALS AND METHODS A total of 42 patients who underwent resection of urothelial carcinoma metastases with curative intent at 4 Japanese university hospitals were included in analysis. Of the patients 41 of 42 underwent systemic(More)
OBJECTIVES We retrospectively analyzed the survival of renal cell carcinoma patients with bone metastases, and identified prognostic factors and a model predictive for survival in these patients. METHODS Fifty patients with renal cell carcinoma with osseous metastases were treated at Hokkaido University Hospital between 1980 and 2004. The relationship(More)
Fish oil, which is rich in eicosapentaenoic acid (EPA), has been found to have immunomodulatory effects. We examined whether administration of purified EPA affected survival of fully mismatched murine cardiac allografts. Hearts from C57BL/10 (H-2(b)) mice were transplanted into CBA (H-2(k)) recipients treated with one intraperitoneal dose of purified EPA(More)
UNLABELLED What's known on the subject? and What does the study add? Radical cystectomy remains associated with comparatively high perioperative morbidity and mortality, despite improvements in surgical techniques and perioperative care. At present, most studies on the complications associated with open radical cystectomy were derived from Western academic(More)
OBJECTIVES To determine the role of lymph-node (LN) dissection in patients undergoing surgery for upper urinary tract (UUT) cancer. PATIENTS AND METHODS We reviewed the clinicopathological data from 312 patients with UUT cancer treated predominantly by nephroureterectomy. The relationship between clinical characteristics and cancer-specific survival (CSS)(More)
We describe our experience with complete repair of severe penoscrotal hypospadias in 1 stage. The operative technique includes several innovative points, such as release of chordee by urethral mobilization (without detaching it from the glans) after penile degloving of dartos chordee, wing flap-flipping urethroplasty to the tip of the glans and(More)
Our experience with one-stage repair of severe perineal hypospadias and scrotal transposition is described. In essence the urethra is formed by our (extended parameatal) wing flap-flipping method, while the scrotum is normally repositioned with skin closure. Comparison is made with other repairs, while the safety of the extended parameatal pedicle flap is(More)
