Characterization of the Pudendal Nerve with Transvaginal Ultrasonography

NCT06021782 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 24

Last updated 2025-01-29

No results posted yet for this study

Summary

This is a feasibility study characterizing the ability of transvaginal ultrasonography to identify the pudendal nerve. Today, the pudendal nerve block is typically accomplished through blind landmark techniques, thus limiting its success. To date, there has never been an attempt to determine if the visualization of the pudendal nerve would be possible using transvaginal ultrasound with existing technology; nor to perform this procedure transvaginally with the assistance of ultrasound.

Conditions

  • Anesthesia

Interventions

OTHER

All subjects-Observation

The sonographer or study team member will scan the lateral vaginal walls (Left and right) directing the probe slightly caudad in direction of the ischial spine (IS). The IS is very echogenic and easily identifiable (bony landmark). Anatomically, the pudendal nerve courses underneath the IS and travels with the vascular bundle of the pudendal artery and pudendal vein. The artery and the vein will be identified using color flow Doppler at the time of the scan. These landmarks, IS, pudendal artery and vein will serve as the basis for the identification of the pudendal nerve.
