Abstract
BACKGROUND: The therapeutic role of extracorporeal shockwave therapy (ESWT) for Peyronie's disease (PD) has been controversial in a long term. We aimed to further evaluate the therapeutic effect of ESWT for PD on the basis of available high-quality studies. METHODS: The PubMed, CENTRAL and Embase databases were searched for articles published from January 1st, 2000 to December 31, 2022. Only randomized controlled trials (RCTs) using ESWT to treat PD were included. Meta-analysis and forest plots were carried out using Review Manager 5.4.1 software, and outcomes were reviewed by 2 authors independently. Using the Risk of Bias assessment form (ROB-2) by Cochrane Collaboration for quality assessment. PRISMA 2020 guidelines were used in this article to achieve the quantitative and qualitative synthesis of data. RESULTS: A total of four RCTs were included. 151 patients in the ESWT group and 150 patients in the control group. The meta-analysis results showed that ESWT could significantly reduce plaque size (OR 2.59, 95%CI 1.15 to 5.85, P = 0.02) and relieve pain (MD -1.55, 95%CI -2.46 to -0.64, P = 0.0008); but it has no significant effect on reducing the penile curvature (OR 1.93, 95%CI 0.87-4.26, P = 0.11) and improving sexual function (MD 2.6, 95%CI -1.63 to 6.83, P = 0.23), there is also no significant difference in complication rates between groups (OR 2.94, 95%CI 0.66 to 13.03, P = 0.16). The risk of bias of results is low. The limitations of this study are that the number of included studies is too small, some experimental outcomes are missing, and the expression of outcomes is not unified. CONCLUSIONS: For PD, ESWT can be considered as a safe short-term treatment, which can reduce plaque size and relieve pain, but cannot improve penile curvature and sexual function. Its long-term efficacy remains to be discussed. REGISTRATION NUMBER: PROSPERO (ID: CRD42023436744).
