Suprapubic pressure facilitates the procedure of office hysteroscopy: A randomized controlled trial.

AIM: To minimize the experienced pain during office hysteroscopy, a number of technical approaches and maneuvers are used. The aim of the study was to assess the effect of suprapubic pressure (SuPuP) applied during hysteroscopy. The impact of this maneuver on experienced pain (assessed by visual analog scale [VAS]) and duration of passage through the cervical canal was measured and compared to a reference group with no SuPuP.

METHODS

Hysteroscopy was performed in study subjects as part of their infertility work-up. Patients were randomized into two groups as part of a controlled trial. In group 1, SuPuP was applied while inserting the scope; in group 2, SuPuP was not applied. Pain experienced during the procedure was measured on a 0-10 VAS. Duration of passage through the cervical canal was measured by analyzing the video of the procedure. The effect of SuPuP was estimated by testing for between-groups differences in these outcomes.

RESULTS

The number of patients included the study was 60. Mean (SD) VAS score was 3.40 (1.276) in group 1 compared to 3.33 (0.802) in group 2 (P = 0.809). Mean (SD) time of passage through the cervical canal in group 1 was 30.5 (18.37) seconds compared to 43.0 (24.51) seconds in group 2 (P = 0.029).

CONCLUSION

Applying suprapubic pressure could facilitate the procedure by significantly shortening the duration of the passage through the cervical canal, but significantly not reduces the pain experienced during hysteroscopy. Further studies are to be undertaken to investigate the advantages of suprapubic pressure during office hysteroscopy.
