[Incidences of erectile dysfunction and retrograde ejaculation after suprapubic prostatectomy and transurethral resection of the prostate in Chinese men: a meta-analysis].

OBJECTIVE
To compare suprapubic prostatectomy (SPPC) with transurethral resection of the prostate (TURP) in inducing erectile dysfunction (ED) and retrograde ejaculation (RE) in Chinese men.


METHODS
We retrieved all the case-controlled studies on the comparison of SPPC and TURP in inducing ED and RE by searching Medline and Chinese Journal Full-text Database (CJFD) (up to January 2009), screened the eligible literature according to the selection and exclusion criteria, and performed meta-analyses on the included studies using the software Revman 4. 2.


RESULTS
Eight eligible reports were identified in this study, including 515 cases of SPPC and 462 cases of TURP. The SPPC group showed a little higher incidence of ED than the TURP group (pooled OR: 1.34; 95% CI, 0.97, 1.85), with no statistically significant difference (P > 0.05), while the latter exhibited a significantly higher incidence of RE than the former (pooled OR: 0.58; 95% CI, 0.44, 0.76, P < 0.05).


CONCLUSION
There is no significant difference between the incidence of ED after SPPC and that after TURP in Chinese men, but the latter may induce a much higher rate of retrograde ejaculation than the former.
