Use of Saline Infusion Sonography to Evaluate Intrauterine and Tubal Factors in Subfertile Patients

This study aims to observe and report on the use of saline infusion sonography (SIS) to find out intrauterine and tubal factors in infertile/subfertile women, focusing on its diagnostic use, clinical advantages, and practical implications. A prospective observational study was conducted involving 86 women presenting with subfertility and/or recurrent pregnancy loss in a tertiary care hospital. These participants were selected based on inclusion and exclusion criteria relevant to the study objectives. SIS was performed using B-mode ultrasonography and Doppler techniques, involving the instillation of saline transcervically into the cavity of the uterus. The procedure's use in evaluating uterine and tubal pathology was observed. SIS demonstrated reasonable diagnostic use in detecting uterine anomalies, including polyps and leiomyomas. The technique also assessed tubal patency, though pinpointing the exact site of obstruction was challenging. The procedure was well-tolerated, with minimal discomfort reported by the patients. The single-center design and limited sample size of the study are among its drawbacks, which could affect the generalizability of the findings of this research. SIS is a valuable, minimally invasive diagnostic tool for assessing uterine and tubal factors in subfertile women. It offers high diagnostic value, low risk of complications, and improved patient comfort compared to traditional methods.
