Abstract

Introduction and hypothesis

Today laparoscopic hysterectomy (LH) can be performed safely and effectively, even for women with a previous history of cesarean section (CS). However, it is unclear whether the risk of urinary tract injury increases with previous CS during LH.

Methods

PubMed and Embase databases were searched for all studies on previous history of CS and risk of urinary tract injuries during and after LH. Reference lists of the identified studies, reviews, and other relevant publications were also searched. Urinary tract injuries or related complications were the outcomes of interest. Meta-analysis was conducted using an inverse-variance weighted random-effects model.

Results

A total of 7 studies including 3,191 patients were identified in the meta-analysis. Overall, the pooled relative risk (RR) and the corresponding 95 % confidence interval (CI) of urinary tract injury were 3.48 (1.86–6.50) for previous CS compared with no previous CS. However, only two studies reported sufficient data on ureteral injury, and the combined RR was 1.83 (95 % CI 0.19–17.26). All seven studies reported the outcomes of bladder injury, and the pooled RR was 3.75 (95 % CI 1.96–7.17). Stratified analyses showed a basically consistent result with the overall analysis except for that by 1–2 times of previous CS (RR 2.32, 95 % CI 0.56–9.56).

Conclusions

Previous CS is significantly associated with development of bladder injury during LH. No significant association was found yet between previous CS and risk of ureteral injury. Given the limited number of studies, more future studies are required to confirm the associations.
