Efficacy of kidney-tonifying traditional Chinese medicine prescriptions in hypoplastic uterus treatment: a systematic review and meta-analysis.

AIM

To review and evaluate the efficacy of kidney-tonifying traditional Chinese medicine prescriptions (KT-TCMP) in hypoplastic uterus (HU) treatment.

METHODS

We searched MEDLINE, the Cochrane Library, CNKI (China National Knowledge Infrastructure), WANFANG and VIP databases until 14 December 2013 independently with two investigators. Randomized controlled trials (RCT) involving KT-TCMP as a combined or monotherapy in the treatment of HU were reviewed and analyzed. Meta-analysis was performed by Review Manager (version 5.2).

RESULTS

Nine RCT of 1745 patients were eligible for this review and meta-analysis, of which eight RCT described the primary outcome of clinical efficacy and three RCT drew the secondary outcome of uterine size. Meta-analyzed 'recovery' clinical efficacy of KT-TCMP in seven RCT was conducted which considered diethylstilbestrol therapy alone as control, as well as three RCT that meta-analyzed the effect of KT-TCMP on uterine diameter enlargement. As a result, KT-TCMP therapy had a significantly improved difference in increasing 'recovery' clinical efficacy (risk ratio, 2.34; 95% confidence interval [CI], 1.90-2.89) and enlarging the uterine diameter (standardized mean difference, 1.62; 95% CI, 1.39-1.84). One study reported adverse reactions as an important outcome and found it was safe during KT-TCMP therapy.

CONCLUSION

The therapy of applying KT-TCMP as a combined or monotherapy in the treatment of HU may be more efficacious. However, these RCT were of moderate methodological quality and small sample size; thus, the results should be confirmed with more rigorously controlled further studies.
