Utility of Saline Infusion Sonohysterography in Gynecology: A Review Article

This study aimed to describe the role played by saline infusion sonohysterosalpingography (SIS) in the evaluation of uterine lesions. Saline infusion sonohysterosalpingography provides three-dimensional (3D) images with high resolution, which, in turn, gives a good orientation to clinicians and radiologists, in most cases, about the underlying endometrial and tubal pathologies. Saline infusion sonohysterosalpingography is an underused imaging modality that has some advantages over other conventional imaging modalities. It can be used in the diagnosis of gynecological conditions. Saline infusion sonohysterosalpingography gets an edge over other modalities because of its ease of use, cost efficacy, and non-invasive nature while having comparable or even better accuracy than most imaging modalities used in gynecological conditions. Its cost efficacy and excellent pathological characterization make it an imaging modality beneficial for Indian healthcare setups as a whole, and rural healthcare setups in particular where patients cannot afford expensive investigations. This review covers indications and contraindications, imaging technique, drawbacks in imaging, use of SIS in various uterine pathologies, and, in the end, a comparison of SIS with other imaging modalities. Saline infusion sonohysterosalpingography is indicated in most of the prevalent gynecological diseases in India with the reported post-procedural complications being very few. There are a few contraindications as well which should be kept in mind and these are mentioned later. During the procedure, aseptic precautions should be taken. Comparison between imaging modalities will bring out the better modality for a particular case according to the need of the patient.
