Impact of uterine cavity filling pressure levels on pain and procedure duration in diagnostic hysteroscopy: A retrospective cohort study

This study investigates the impact of intracavitary pressure levels on pain, visualization quality, and procedure duration in office hysteroscopy, comparing standard pressures (60-100 mmHg) with high pressures (110-150 mmHg). We conducted a retrospective cohort study involving non-menopausal women undergoing diagnostic hysteroscopy at a tertiary clinic. Patients were categorized into two groups based on intracavitary pressure: the standard pressure group (60-100 mmHg; n = 72) and the high-pressure group (110-150 mmHg; n = 37). Outcomes measured included pain scores, procedure duration, and fluid volume used. Logistic regression was employed to identify risk factors for severe pain. The high-pressure group demonstrated significantly shorter procedure durations compared to the standard pressure group (96.56 ± 34.36 vs. 163.00 ± 61.78 s, p
