OBJECTIVES To determine the accuracy of orchidometry and ultrasonography for measuring the testicular volume by comparing the resultant measurements with the actual testicular volume in humans. METHODS The testicular volume of 40 testes from 20 patients with prostate cancer (mean age +/- SD 74.5 +/- 7.5 years) was measured using the Prader orchidometer(More)
The objective of this study was to evaluate the utility of the Hounsfield Unit (HU) values as a predictive factor of extracorporeal shock wave lithotripsy outcome for ureteral and renal stones. We also assessed the possibility that HU values could be used to predict stone composition. A retrospective study was performed to measure stone HU values in 260(More)
Many mechanisms involving TNF-alpha, Th1 responses, and Th17 responses are implicated in chronic inflammatory autoimmune disease. Recently, the clinical impact of anti-TNF therapy on disease progression has resulted in re-evaluation of the central role of this cytokine and engendered novel concept of TNF-dependent immunity. However, the overall relationship(More)
Androgen deprivation therapy is the mainstay of treatment for prostate cancer. Given its frequent failure, new therapy that reduces prostate cancer progression would be a breakthrough in treating this disease. Bisphosphonates are well-established agents for treating skeletal-related events (SREs) in prostate cancer patients with bone metastases. Exposure to(More)
AIM To evaluate the relationship between testicular function and testicular volume measured by using Prader orchidometry and ultrasonography (US) to determine the critical testicular volume indicating normal testicular function by each method. METHODS Total testicular volume (right plus left testicular volume) was measured in 794 testes in 397 men with(More)
OBJECTIVES To compare the accuracy of testicular volume measurements with the Prader orchidometer versus ultrasonography. METHODS The volume of 938 testes in 469 men with infertility (mean age 35.8 years) was measured using a Prader orchidometer and by ultrasonography. The ultrasound testicular volumes were calculated using the formula length x width x(More)
OBJECTIVES To determine the prevalence of testicular microlithiasis (TM) seen by testicular ultrasonography (US) in Japanese adult men referred for andrologic symptoms and evaluate associations of TM with pathologic conditions. METHODS For 7 years, US was performed in 969 patients (mean age 40.9 years) at one institution. The patients were divided into(More)
AIM Hemodynamic changes with aging in the penile arterial circulation, including the helicine arteries, were evaluated with power Doppler imaging in erectile dysfunction patients with a normal response to prostaglandin injection. METHODS In 36 patients with erectile dysfunction and no definite vascular risk factors, 72 corpora were examined using power(More)
BACKGROUND Circulating tumor cells (CTCs) have been shown to aid in the therapeutic management of patients. But, only a few attempts have been made at the detection of urothelial cancer cells in the blood. The purpose of this study was to test the hypothesis that CTCs are detected in patients with urothelial cancers using newly developed CellSearch Assay.(More)
BACKGROUND Immunotherapy with bacillus Calmette-Guérin (BCG) for bladder cancer is successful, although the precise mechanism is unclear. Natural killer (NK) cells are a candidate for BCG-activated killer cells, but the roles of other T lymphocytes, such as NKT cells and gammadeltaT cells, are not fully understood. Mycobacterium tuberculosis is a potent(More)
