BACKGROUND This study was performed to evaluate late effects on the lower urinary tract after radical hysterectomy. METHODS We studied 9 women treated with radical hysterectomy for cervical cancer. All patients underwent surgery more than 10 years age (range, 14 to 36 years). Six patients had urologic complications associated with lower urinary tract(More)
BACKGROUND Elastography is a diagnostic imaging technique that evaluates the hardness of a lesion. It is expected to become a new diagnostic modality for prostate cancer. The aim of this study was to examine the usefulness of elastography in the diagnosis of prostate cancer. METHODS A total of 29 patients with untreated, histologically proven prostate(More)
PURPOSE We investigated the feasibility of augmentation in a diseased bladder with a bladder acellular matrix graft. MATERIALS AND METHODS In 50 female Sprague-Dawley rats chemical cystitis was induced by intravesical instillation of HCl repeated monthly to maintain chronic inflammation. Urodynamic studies were performed in all rats 1 week after the(More)
A 55-year-old woman had a right renal tumor incidentally diagnosed by ultrasonography. CT revealed a perirenal low density mass 3 cm in diameter. Dynamic CT showed peripheral enhancement of the tumor in early phase and internal homogeneous enhancement in delayed phase. Since hemangioma was considered most likely, we performed tumor resection and spared the(More)
BACKGROUND A prospective study was performed to investigate combined treatment with intra-arterial chemotherapy and radiation therapy for bladder preservation in locally invasive bladder cancer. METHODS Patients with invasive bladder cancer, stage T2-3N0M0, were included in the study. Intra-arterial chemotherapy was performed with three injections of(More)
OBJECTIVE To examine the lower urinary tract function of a rat lumbar canal stenosis (LCS) model by in vivo cystometry before and after α1 adrenoceptor antagonist or cholinesterase inhibitor administration. MATERIALS AND METHODS One small hole was drilled at the fifth lumbar vertebral arch, and a rectangular piece of silicone rubber was inserted into the(More)
BACKGROUND Rhabdomyosarcoma (RMS) is one of the most common soft tissue sarcomas among children. Patients who developed genitourinary/pelvic rhabdomyosarcoma (GU/P-RMS) have a higher complication ratio and relatively poorer event free survival, with local therapy being very important. While proton beam therapy (PBT) is expected to reduce co-morbidity,(More)
OBJECTIVES The objective was to develop an underactive bladder (UAB) model in primates and to evaluate the potential of prostanoid EP2 and EP3 receptor dual agonist ONO-8055 to become a therapeutic agent for UAB. METHODS A surgical procedure resembling radical hysterectomy was performed on female cynomolgus monkeys. Subsequently, in vitro muscle strip(More)
A 69-year-old man was hospitalized for treatment of a left renal tumor. The tumor had originally been demonstrated as a simple renal cyst 4 years before. However, the size of the tumor decreased, and at the time of hospitalization, the tumor showed a solid, papillary component that was enhanced by contrast medium on computed tomography (CT) and had high(More)
Two cases of Fibroepithelial polyp in 47-and 74-year-old males complaining of gross hematuria are described. In the foreign literature, this polyp most commonly occurs in infancy and childhood in the first decade of life, but rarely occurs in aged male. Ten cases of this disease could be accumulated in the Japanese literatures, in which this polyp more(More)
