PURPOSE Recent studies have suggested that lymph node dissection may improve the prognosis in patients with upper tract urothelial carcinoma. Therefore, patients who will benefit from lymph node dissection need to be selected before surgery. Because patients who have extraurothelial recurrence theoretically include those whose prognoses are improved by(More)
OBJECTIVES The possible relationship between urological disease and inferior vena cava (IVC) reflux was examined. METHODS Transabdominal color Doppler ultrasonography of the IVC was performed. The patient was placed supine and the convex probe was positioned in vertical to the upper abdominal wall. Then the extent of reflux in the IVC accompanying each(More)
PURPOSE We investigated the mechanisms by which Eviprostat, a phytotherapeutic drug for benign prostatic hyperplasia, influences bladder activity in rats. MATERIALS AND METHODS A total of 42 female rats were divided into a control group and an Eviprostat group. Rats in the control group were fed a standard diet, while animals in the Eviprostat group were(More)
The specificity of monoclonal antibodies represents a potential therapeutic advantage, but their use as single agents in oncology has proven limited to date. The development of antibody-drug conjugates (ADCs) takes advantage of the specificity of the monoclonal antibody and potent cytotoxic effect of chemotherapy, leading to enhanced cytotoxicity in target(More)
Purpose The TAXYNERGY trial ( identifier: NCT01718353) evaluated clinical benefit from early taxane switch and circulating tumor cell (CTC) biomarkers to interrogate mechanisms of sensitivity or resistance to taxanes in men with chemotherapy-naïve, metastatic, castration-resistant prostate cancer. Patients and Methods Patients were(More)
We examined the effects of propiverine hydrochloride and naftopidil on the urinary ATP level and bladder activity after bladder stimulation in rats. Thirty-nine female rats were divided into a control group, a propiverine group, and a naftopidil group. Rats in the propiverine and naftopidil groups were administered 1 ml/day of propiverine or naftopidil(More)
INTRODUCTION The purpose of this study was to evaluate prognostic factors for patients with upper urinary tract urothelial carcinoma (UUT-UC) after nephroureterectomy and to seek a better way of finding more favorable clinical results for these patients. PATIENTS AND METHODS We retrospectively reviewed the medical records of 121 UUT-UC patients who(More)
Patients with pT1aN0M0 renal cell carcinoma (RCC) generally have good prognosis, and recurrence is rare. However, metastasis develops postoperatively in a small number of patients with pT1aN0M0 RCC. The present study was undertaken to identify predictors for recurrence in patients with pT1aN0M0 RCC. We reviewed the clinicopathological factors of 133(More)
1. Active and inactive renin were assayed in plasma of the renal veins and the inferior vena cava below the kidney in eight patients with hypertension and unilateral renal abnormalities, 20 min after the patients had resumed the upright position. 2. The concentration of active renin on the affected side was significantly higher than that on the non-affected(More)
