Conventionally, a 20mL syringe is employed for contrast agent injection, either at a constant or pulsatile pressure. However, in cases of bilateral fallopian tube obstruction, continued injection can lead to discomfort and excessive pressure within the uterine cavity, necessitating discontinuation of the examination.Case Presentation: In this illuminating case study, a patient underwent TVS 4D-HyCoSy due to infertility concerns. Initial contrast agent injection failed to visualize both fallopian tubes, accompanied by acute pain. Bilateral tubal obstruction was diagnosed, prompting an innovative approach. A 2.5mL syringe was chosen for pulsed injection, leading to successful visualization of patency in one fallopian tube. Remarkably, the patient achieved natural pregnancy within three months of the examination.Conclusion: Pulsed injection using a small-volume syringe emerges as a promising technique in cases of fallopian tube obstruction during TVS 4D-HyCoSy. This method not only enhances patient comfort but also improves the likelihood of visualizing fallopian tube patency, contributing to accurate infertility assessments. As a supplementary technique, it addresses limitations associated with constant pressure injection and offers a novel approach to enhance diagnostic success.Keywords: hysterosalpingography, tubal obstruction, contrast agent, pulsed injection, small-volume syringe
