To evaluate the efficacy and safety of different kinds of PDE5-Is with tamsulosin as a medical therapy for LUTS secondary to benign prostatic hyperplasia: A protocol for systematic review and meta analysis
Abstract
Abstract Background: Drug therapy for lower urinary tract symptoms (LUTS) secondary to benign prostate hyperplasia (BPH) is a major and popular method. However, the therapeutic strategy is still not clear enough up to now. The purpose of this study was to compare the relative safety and efficacy of different types of phosphodiesterase type 5 inhibitors (PDE5-Is) with tamsulosin for the treatment of LUTS secondary to BPH. Methods: Databases including PubMed, OpenGrey, Embase, Cochrane Library, and Web of Science will be searched to identify qualified studies. We will use the Stata version 13.0 to conduct the network meta-analysis (NMA) with a random or fixed effects model of Bayesian framework. International prostate symptom score (IPSS), maximum urinary flow fate (Qmax) and their credible intervals (CI) will be used to compare every medical intervention with the efficacy and safety, including sildenafil plus tamsulosin, tadalafil plus tamsulosin, vardenafil plus tamsulosin. And the ranking of probability of different interventions will be estimated by comparing the surface under the cumulative ranking curve (SUCRA). Results: A high quality-synthesis of the current evidence for comparing with different doses or types of PDE5-Is combined with tamsulosin to the treatment of LUTS secondary to BPH will be provided. Conclusions: This NMA and systematic review will generate evidence to help choose the best combination for treatment of LUTS secondary to BPH. PROSPERO registration…
