Abbreviations & AcronymsAbstract: Premature ejaculation is a common sexual problem, as is erectile dysfunction. We evaluated silodosin, a highly selective a1A-adrenoceptor antagonist, as a new treatment option for premature ejaculation. a1-Adrenoceptor antagonists are widely used for lower urinary tract symptoms, and clinical studies on silodosin have shown excellent clinical efficacy for lower urinary tract symptoms. However, compared with other a1-adrenoceptor antagonists, silodosin appeared to suppress ejaculation in a relatively higher percent of trial participants. This suppression of ejaculation by silodosin suggested its potential for treating premature ejaculation. Consequently, we evaluated the feasibility of off-label silodosin as a new treatment option for premature ejaculation. Eight patients suffering premature ejaculation were treated with silodosin. Silodosin (4 mg) was given 2 h before sexual intercourse. Intravaginal ejaculatory latency time, premature ejaculation profile item, clinical global impression change in premature ejaculation and systemic adverse events were recorded. Intravaginal ejaculatory latency time was significantly prolonged (from 3.4 min to 10.1 min, P = 0.003). All patients answered better (much better) or slightly better for their own premature ejaculation problem compared with pretreatment condition in the clinical global impression change. Premature ejaculation profile also significantly improved. Two (25%), three (37.5%) and seven patients (87.5%) experienced anejaculation, reduced semen volume and discomfort during orgasm, respectively. However, these problems were not of major concern for the participants. No systemic adverse effects were reported. The current results support the possible use of silodosin as a new treatment option for premature ejaculation, and suggest that a placebo controlled study assessing its clinical usefulness would be worthwhile.

Aim : Patients with superficial bladder tumors sometimes have long recurrence-free intervals. We evaluated whether patients with long recurrence-free periods had subsequent recurrences. We also clarified how these patients should be followed. Materials and methods : We enrolled 244 patients with superficial bladder cancer (62 pTa and 182 pT1) treated by transurethral resection of bladder tumor (TURBT) and adjuvant chemotherapy with pirarubicin. Median follow up was 75.5 months. Patients were stratified by the length of their recurrence-free interval. Results : Recurrences occurred in 124 patients (50.8%). Of 185 patients who did not have a recurrence for the first 3 years, subsequent recurrences occurred in 65 patients; in more than half the first recurrence developed after 5 years or more. Ta tumors had a low recurrence rate (14.5%) with the first recurrence often developing after a long recurrence-free period. Of 40 patients who remained recurrence-free for 3 years or more after at least one recurrence occurred, 16 patients (40%) had subsequent recurrences. Furthermore, most of these patients who remained free of recurrence for more than 5 years eventually had a recurrence. The overall progression rate was 15.6%, and this did not relate to the length of the recurrence-free interval. Conclusion : When patients did not have a recurrence for the first 3 years, tumors subsequently often recurred, even in pTa tumors. In patients with at least once recurrence, subsequent recurrences appear to occur irrespective of the length of the recurrence-free period. Thus, we recommend that all patients with superficial bladder tumors be followed for as long as possible.

Primary signet-ring cell carcinoma (SRCC) of the prostate is very rare and has a poor prognosis, even when treated with aggressive therapy. We report herein a case of a 72-year-old man with prostatic SRCC. The patient had a tumor that extended directly to the rectum. Maximal androgen blockade was started and 20 months later, the patient was alive without evidence of recurrence. The present case of prostatic SRCC responded well to medical therapy, however, tumors can recur after a long period of time. Therefore, adjuvant therapy is recommended.

Methods: A total of 190 patients who had undergone retropubic radical prostatectomy were evaluated. Urine loss ratio was measured using the 24-h pad test during 7 consecutive days after removal of urethral catheters. Continence rates at 1, 3, 6 and 12 months after operation were evaluated with the urinary function domain of the University of California, Los Angeles Prostate Cancer Index. The desirable urine loss ratio for continent condition at 12 months after the operation was calculated. As desirable target urine loss ratio continence at 12 months was determined by using logistic analysis. Results: Continence rates of all patients at 1, 3, 6 and 12 months after surgery were 13%, 37.8%, 58.9%, and 85.8%, respectively. Continence rates of patients who achieved ≤1% of urine loss ratio within 7 days or ≤5% urine loss ratio within 3 days after catheter removal was 100% at 12 months. Logistic regression analysis proved these urine loss ratio values were significant predictors of continence at 12 months. Conclusions: Urine loss ratio after catheter removal within 7 days is a significant determinant of urinary continence after radical prostatectomy. This parameter could have clinical usefulness to estimate future recovery of urinary continence.
