Abstract:

Objective

To evaluate the efficacy and safety of superselective renal arterial embolization in the treatment of iatrogenic renal hemorrhage.

Methods

Multiple Chinese and English databases were electronically searched as of April 9, 2021. Two reviewers independently screened the literature, extracted the data and assessed the risk of bias of the included studies, then, meta-analysis was performed by using R version 3.6.0 software and Stata 12.0 software.

Results

The total of 13 studies met the inclusion criteria and included 293 patients. Percutaneous nephrolithotomy was the main cause of iatrogenic renal hemorrhage, which proportion was 53.04% (95%CI: 36.59, 69.49), and the complete hemostasis rate was greater than 99% (95%CI: 98, 100), the single-embolization hemostasis rate was 96% (95%CI: 91, 99), the proportion of secondary-embolization hemostasis was 8% (95%CI: 5, 12), and the incidence of adverse events, post-embolism syndrome,was 21% (95%CI: 12, 34).

Conclusions

Superselective renal artery embolization is an effective method for the treatment of iatrogenic renal hemorrhage with high success rate, safety and effectiveness, and fewer adverse reactions, which is worthy of wide application and promotion.

Key words: Meta-analysis, Superselective renal artery embolization, Iatrogenic renal hemorrhage, Postembolism syndrome
