Efficacy of combination therapy of tamsulosin and solifenacin for mild and moderate benign prostatic hyperplasia with overactive bladder / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of the combination therapy of tamsulosin and solifenacin for mild and moderate benign prostatic hyperplasia (BPH) with overactive bladder (OAB).</p><p><b>METHODS</b>We randomly divided 166 patients with BPH and concomitant OAB into a mild obstruction symptom group (n = 88) and a moderate obstruction symptom group (n =78), 48 of the former group treated with 0. 2 mg tamsulosin + 5 mg solifenacin and the other 40 with 0. 2 mg tamsulosin; 36 of the latter group treated with 0. 2 mg tamsulosin + 5 mg solifenacin and the other 42 with 0. 2 mg tamsulosin, all administered once daily for 12 weeks.

The combination therapy exhibited an obvious superiority over tamsulosin alone in improving IPSS (9.7 micro 3.0 vs 15.8 micro 3.3), USPSS (8. 1 micro 1.7 vs 12.3 micro 3.1), Qmax ([18.6 micro 2.3] ml/s vs [14.2 micro 2.3] ml/s ), and OABSS (5.3micro 1.3 vs 9.7 micro 2.7) (P < 0.05), but there were no obvious differences in residual urine, urine routine test results and adverse events between the two therapies ( P > 0. 05). In those with moderate obstruction symptoms, the combination therapy significantly improved IPSS, VSS, Qmax and OABSS (P < 0.05) but not the residual urine (P > 0. 05) in comparison with the baseline. The tamsulosin therapy achieved obvious improvement in IPSS, VSS, Qmax, OABSS and residual urine. The combination therapy showed a better effect than tamsulosin only in OABSS (4. 8 +/-1.5 vs 6.5 +/-2.5, P < 0.05), but no significant differences from the latter in IPSS, Qmax, VSS, routine urine test results, and adverse</p><p><b>CONCLUSION</b>Combination therapy of tamsulosin and solifenacin is obviously safe and efficacious in the treatment (P > 0.05). events of both mild and moderate BPH with concomitant OAB, and it is superior to tamsulosin alone.</p>

Sexual function of men with symptomatic benign prostatic hyperplasia and effect of Tamsulosin / 中华男科学杂志

<p><b>OBJECTIVE</b>To study the sexual function of men with benign prostatic hyperplasia (BPH) with the lower urinary tract symptoms (LUTS) and the effect of Tamsulosin.</p><p><b>METHODS</b>One hundred and ninety-two cases of BPH accompanied with typical LUTS were investigated using the International Prostate Symptom Score (IPSS), Quality of Life (QOL), International Index of Erectile Function 5 (IIEF-5) and measuring the flow rate of urine before treatment. The patients were randomly divided into two groups, the treatment group (n = 103) given Tamsulosin 0.2 mg, and the control group (n = 89) taking placebo once a day for 8 weeks. The influence of various factors on sexual function was analyzed before and after treatment.</p><p><b>RESULTS</b>The mean scores of IPSS, QOL, Qmax and IIEF-5 were (20.20 +/- 6.81), (4.51 +/- 0.76), (9.60 +/- 8.79) ml/s and (9.80 +/- 8.62), respectively. The incidence of erectile dysfunction was 75% (144/192). There was statistically significant correlation between age and IPSS score (r = 0. 203, P < 0. 005) or IIEF-5 score (r = -0.571, P < 0.001) as well as between IPSS and IIEF-5 scores (r = - 0.312, P < 0.001). Various indexes were significantly improved after Tamsulosin treatment as compared with pre-treatment (P < 0.001) and placebo administration (P < 0.001), but no significant difference in various indexes was observed in the control group.</p><p><b>CONCLUSION</b>Age and LUTS are dangerous factors for sexual function, and the severity of LUTS is closely related to the development of sexual dysfunction. Tamsulosin can at once improve the sexual function and the lower urinary tract symptoms of the BPH patients.</p>
