Background: Hydrosalpinx is a frequent tubal pathology encoun- tered among infertile female. Hydrosalpinx impairs the expression of factors essential for differentiation of the endometrium impairing en- dometrial receptivity; reducing the in vitro fertilization success rate. Removal of a hydrosalpinx can increase the implantation rate of in vitro fertilization. However, salpingectomy could potentially affect the ovarian vascularity and may impose a potential change in ovarian Doppler indices. . Objective: to assess the changes in ovarian vascularity following laparoscopic tubal salpingectomy in terms of change in ovarian Dop- pler indices. Setting: Department of Obstetrics and Gynecology, Suez Canal Uni- versity Hospitals, Ismailia, Egypt. Patients and Methods: This prospective cohort study included 25 patients with unilateral communicating hydrosalpinx treated with laparoscopic tubal salpingectomy and ultrasound ovarian Doppler indices were assessed before and after surgery. Main outcome measures: Tubal salpingectomy showed increased local ovarian vascular resistance with significant ovarian Doppler in- dices changes. Results: Both pulsatility index and resistive index increased signifi- cantly 3 months after surgery denoting increased vascular resistance ( p value 0.03 and 0.01 respectively). Conclusion: laparoscopic tubal salpingectomy for treatment of hy- drosalpinx can potentially affect ovarian Doppler indices with signif- icant increase in ovarian local vascular resistance
