Aim The aim of this study was to evaluate and compare lower and higher uterine filling pressures during outpatient diagnostic hysteroscopy. Methods One hundred and seventy‐five women eligible for outpatient diagnostic hysteroscopy were included in this randomized double blind comparative study. The subjects were randomized into two groups. Group 1 ( n = 80) underwent surgery with lower intrauterine filling pressures (30, 40, and 50 mmHg) and group 2 ( n = 81) underwent surgery with higher filling pressures (70, 80, and 100 mmHg). The primary outcome measure was adequate visibility during the procedure. The secondary outcome measure was pain perceived by the patient during and 30 min after the procedure. Results In total, 161 patients completed the trial. Group 2 had significantly higher adequate visibility than group 1 (71/80, 88.75% in group 1 and 79/81, 97.5% in group 2, P = 0.008). There was a trend toward increase in pain scores with higher pressures during the procedure. However, there were no significant differences between the two groups in terms of visual analog scale pain scores measured 30 min after the procedure. Conclusion Lower uterine filling pressure was associated with lower pain scores with a higher trend towards inadequate visibility. It appears that higher filling pressure can be used for performing office hysteroscopy, but it is associated with higher pain scores.
