Laparoscopic transposition and reanastomosis of a circumcaval ureter were performed in a 52-year-old man with right flank pain. A preoperative perfusion pressure study revealed abnormally high intrapelvic pressure. Under laparoscopy, the renal pelvis was divided above the ureteropelvic junction and the ureter was relocated from behind the vena cava. A 5 cm(More)
A case of bladder cancer with simultaneous production of granulocyte colony-stimulating factor (G-CSF) and parathyroid hormone-related protein (PTHrP) is reported. An 81-year-old male patient was admitted to the Saitama Medical School for treatment of gross hematuria, leukocytosis and hypercalcemia and diagnosed as having advanced bladder cancer.(More)
BACKGROUND Clinical differential diagnosis between malignant and benign tumors is important in order to select a therapeutic strategy for a primary retroperitoneal tumor. METHODS The clinical findings and radiological features of 25 patients with primary retroperitoneal tumors were retrospectively evaluated to find those signs that might contribute to the(More)
During the period from 1976 to 1981, 364 patients with bladder carcinoma were seen at the Keio University Hospital. Extensive preoperative investigation of pulmonary, cardiovascular, and renal function was obtained in all patients. Of the 12 patients studied, 9 underwent a one-stage total cystectomy and ileal loop diversion and the remaining 3 a two-stage(More)
Gadolinium-labeled diethylenetriaminepentaacetic acid (Gd-DTPA)-enhanced magnetic resonance imaging (MRI) was evaluated in an effort to clarify whether MRI could replace or be proved to be superior to computerized tomography (CT) and/or transurethral ultrasonography. A total of 57 bladder cancer patients was evaluated. MRI was performed with a(More)
Adrenal tumors would be eminently suitable for laparoscopic surgery because of their size and location. We have performed 25 cases of laparoscopic adrenalectomy, and the purpose of this study was to evaluate the clinical results. Since November 1992, 12 men and 13 women with a mean age of 47.3 (range 29-71) years underwent laparoscopic adrenalectomy.(More)
Morphologic changes in hyperplastic prostate tissue following three different treatments were analysed by MRI using an endorectal surface coil. In cases treated by TUMT, the MRI findings of the prostate showed hemorrhagic necrosis, which was absorbed in 12 weeks, and a widened prostatic urethra. In cases treated by laser ablation, the thermal effect went(More)
Carboplatin, an analog of cisplatin, was evaluated in a phase II study involving 25 patients with advanced testicular tumor and 45 with transitional cell carcinoma (TCC) of the urinary tract; 21 and 38 cases, respectively, were evaluable for response. Prior treatment with cisplatin-based chemotherapy had occurred in 7 of the testicular cancer patients and(More)
Therapeutic guide for renovascular hypertension has been greatly changed by a development of beta-blockers and captopril, and an introduction of percutaneous transluminal angioplasty (PTA) The accepted opinion was that surgical therapy was superior to drug therapy since Hunt & Strong reported the follow-up results in 1973. However, efficacy of drug therapy(More)
Transcatheter injection of ethanol into the renal artery was utilized in 11 patients with hypernephromas, clincally staged C or D, in an attempt to produce renal devitalization. Complete disappearance of the tumor neovascularity was achieved in 9 of 11 patients. Renal divitalization with ethanol injection is safer and more effective than the embolizing(More)
