Abstract

Abstract : Background: The most common tubal disease leading to infertility occurs in the distal region, manifesting as hydrosalpinx. Tubal surgery is an effective alternative treatment. However, subpopulations that benefit the most from tubal repair surgery remain unclear. The objective of this study was to investigate the natural pregnancy outcomes of patients with hydrosalpinx after reproductive surgery and those with different grades of hydrosalpinx. Methods: We searched the major online databases (PubMed, Embase, Cochrane Library, Web of Science, and Clinical Trials) to collect observational studies on patients with hydrosalpinx who underwent surgeries to preserve natural fertility from January 2000 to August 2022. The outcome indicators were natural intrauterine pregnancy (IUP) and ectopic pregnancy (EP) rates. Studies on patients with hydrosalpinx who underwent laparoscopic surgeries and those who intended to be conceived naturally were included. Studies on patients with non-hydrosalpinx diseases, those who underwent open surgery, and those who intended to undergo assisted conception were excluded. The Newcastle–Ottawa scale for observational studies was used for quality evaluation. Meta-analysis of a single rate was performed using RevMan5.3 software. Results: A total of 10 articles were included in this study, including 1317 patients with hydrosalpinx. Seven studies were retrospective and 3 were prospective. It was found that after surgery for preserving natural fertility function, the IUP and EP rates of patients with hydrosalpinx were 27% (95% confidence interval [CI]: 22–32%) and 4.8% (95% CI: 2.91–8.26%), respectively. In addition, the IUP and EP rates in patients with mild (n = 254), moderate (n = 252), and severe (n = 473) hydrosalpinx were 50.5% (95% CI: 38.65–61.97%), 32.9% (95% CI: 21.88–46.24%), 10.7% (95% CI: 4.76–21.88%), and 7.4% (95% CI: 2.91–19.35%), 9.09% (95% CI: 6.54–13.79%), 8.3%, 8.26% (95% CI: 3.85–18.03%), respectively. Conclusion: Patients with mild to moderate hydrosalpinx will benefit more from reproductive surgery to improve natural pregnancy outcomes. However, the small sample size in our study needs to be further expanded, and the grouping needs to be more refined, such as grouping based on age. This may provide more guidance in clinical practice.
