Efficacy and tolerability of dapoxetine in the treatment of premature ejaculation / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the efficacy and adverse effects of dapoxetine in the treatment of premature ejaculation.</p><p><b>METHODS</b>We randomly assigned outpatients with premature ejaculation in the proportion of 2:1 to receive 30 mg dapoxetine on demand (n =78) or 50 mg sertraline qd for one month (n = 39). Follow-up was accomplished in 95 cases, 63 in the dapoxetine group and 32 in the sertraline group. We recorded the intravaginal ejaculatory latency time (IELT), clinical global impression of change (CGIC) score, and adverse reactions of the patients and compared them between the two groups.</p><p><b>RESULTS</b>IELT was significantly increased in both the dapoxetine (from [0.87 ± 0.31] to [2.84 ± 0.68] min, P < 0.05) and the sertraline group (from [0.84 ± 0.28] to [2.71 ± 0.92] min, P < 0.05) after medication. Based on the CGIC scores in premature ejaculation, the rate of excellence or effectiveness was 36.5% in the dapoxetine and 37. 5% in the sertraline group, and the rate of improvement was 63.5% in the former and 71.9% in the latter. The incidence rates of dizziness, nausea, headache, and diarrhea were slightly higher (P > 0.05) while those of fatigue, somnolence, and dry mouth significantly higher (P < 0.05) in the sertraline than in the dapoxetine group.</p><p><b>CONCLUSION</b>On-demand oral medication of dapoxetine is effective and well-tolerated for the treatment of premature ejaculation.</p>

Etiology and treatment of bladder spasm associated with benign prostatic hyperplasia / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the etiology and treatment of bladder spasm associated with benign prostatic hyperplasia (BPH).</p><p><b>METHODS</b>Urodynamic tests were performed in 102 cases of BPH before operation. The correlation of bladder spasm with aging, international prostate symptom score (IPSS), quality of life, prostatic volume, operation methods and urodynamic indexes was studied by t and chi2 tests.</p><p><b>RESULTS</b>The incidences of bladder spasm in the lower compliant bladder and unstable bladder were 32.1% (9/28) and 42.5% (13/20), and those after suprapubic prostatectomy and transurethral resection of the prostate (TURP) were 50.9% (26/51) and 23.3% (12/51). There was significant difference between operation methods (P < 0.05).</p><p><b>CONCLUSION</b>Bladder spasm easily develops in the lower compliant bladder and unstable bladder, especially after suprapubic prostatectomy. TURP might decrease the incidence of bladder spasm after BPH operation.</p>

Survey of the prevalence of chronic prostatitis in men with premature ejaculation / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the prevalence of chronic prostatitis in men with premature ejaculation.</p><p><b>METHODS</b>The segmented urine specimens before and after prostatic massage and the expressed prostatic secretion specimens from 106 patients with premature ejaculation and 38 controls were evaluated by microscopic and/or bacteriological studies. The prevalence of premature ejaculation was also investigated in 120 patients with chronic prostatitis.</p><p><b>RESULTS</b>Prostatic inflammation was found in 46.2% and chronic bacterial prostatitis in 34.7% of the subjects with premature ejaculation, respectively. Compared with the controls, the findings were statistically significant (P < 0.05). The prevalence of premature ejaculation in the patients with chronic prostatitis was 47.5% (57/120).</p><p><b>CONCLUSIONS</b>Chronic prostatic inflammation may play a role in the pathogenesis of some cases of premature ejaculation and it is important to give a careful examination of the prostate before initiating any therapy for premature ejaculation.</p>
