[Effects of alpha1 adrenoceptor antagonist, naftopidil, on non-bacterial chronic pelvic pain syndrome in patients with lower urinary tract syndrome: evaluation of its efficacy using NIH-CPSI after 4-week treatment].

We investigated the effect of naftopidil an alpha1 adrenoceptor antagonist on non-bacterial chronic pelvic pain syndrome (CPPS) in middle-aged and older male patients with lower urinary tract symptoms (LUTS). Patients who had given informed consent were treated with naftopidil (daily 50 mg), and were evaluated using the Japanese edition of NIH chronic prostatitis symptom index (NIH-CPSI) and the international prostate symptom score (IPSS) at 2 and 4 weeks after the administration. The NIH-CPSI (total score) was significantly improved by naftopidil for 4 weeks (11.

Discrepancy between the percentage of hypochromic erythrocytes and the reticulocyte hemoglobin content in hemodialysis patients with recombinant human erythropoietin therapy.

The percentage of hypochromic erythrocytes (%HYPO) and the reticulocyte hemoglobin content (CHr) have been used for the diagnosis of iron deficiency (ID). However, we found a discrepancy between %HYPO and CHr values in some hemodialysis patients. Hemodialysis patients receiving recombinant human erythropoietin (rHuEPO) with ID were defined as patients with a %HYPO value exceeding 5%.

[Long-term efficacy of naftopidil for treatment of lower urinary tract symptoms with benign prostatic hyperplasia].

Naftopidil was administered to 67 patients with benign prostatic hyperplasia (BPH) for 12 months. Changes in total/each International Prostate Symptom Score (IPSS) for irritative and obstructive symptoms, nocturia, and residual urine volume were compared before and after its administration. As a result, a significant decrease of score was found in total-IPSS, obstructive and irritative symptoms, which also showed a tendency to decrease at the end of the first month.

[Characteristics of various electrodes for transurethral surgery].

The characteristics of four electrodes for transurethral surgery were examined by resection experiments using porcine muscles. The electrodes were a loop type (uroloop, ENDO care), a roller type (STORZ), VAPOR CUT (STORZ) and WEDGE (Microvasive Co). With the stroke rate fixed at 1.
