1. Indications

Biomechanical mapping, transvaginal, is indicated for the evaluation of various conditions and symptoms related to pelvic floor dysfunction. The following are explicitly provided indications for this procedure:

• Soft Tissue Elasticity Assessment - To evaluate the elasticity of soft tissues in the pelvic region.
• Muscle and Ligament Evaluation - To assess weak or damaged muscles and ligaments that may disrupt pelvic floor support and function.
• Pelvic Floor Dysfunction Symptoms - To investigate symptoms such as urinary incontinence, pelvic organ prolapse, and other related disorders.
• Structural Changes - To identify changes in pelvic floor structure and function due to factors like advanced age, childbirth, genetics, and neurologic conditions.

2. Procedure

The procedure for transvaginal biomechanical mapping involves several detailed steps to ensure accurate assessment of the pelvic floor structures. The following steps outline the process:

• Initial Patient Positioning - The patient is positioned in the dorsal lithotomy position, which allows for optimal access to the vaginal canal. It is essential that the bladder and rectum are emptied prior to the procedure to avoid interference with the measurements.
• Probe Insertion - A specialized probe equipped with tactile sensors is gently inserted into the vagina. This initial insertion is crucial as it provides baseline pressure responses from both the anterior and posterior vaginal walls along the entire length of the vagina.
• Pressure Gradient Calculation - A computer software program calculates the pressure gradient and anatomical dimensions based on the initial pressure responses recorded by the probe. This data is essential for understanding the biomechanical properties of the pelvic floor.
• Compartment Pressure Assessment - The probe is then elevated to capture pressure responses specifically from the apical, anterior, and posterior compartments, which are critical for evaluating the pelvic floor support structures. The pressure gradients and anatomical dimensions for these compartments are also calculated and stored for further analysis.
• Side Pressure Readings - The probe is rotated to obtain pressure readings from the left and right sides of the vagina. This step is important for detecting any asymmetries or irregularities in the pelvic floor structures.
• Circumferential Tactile Imaging - The circumferential tactile image of the vaginal walls is generated, which helps in identifying underlying muscle or tissue irregularities, the presence of foreign bodies, scar tissue, and hypertonic muscle movement.
• Dynamic Muscle Response Measurement - To assess the dynamic response of the pelvic floor muscles, pressure is applied to the lower abdomen by the technician, or the patient may perform a Valsalva maneuver. This step measures how the pelvic floor structures respond to increased intra-abdominal pressure.
• Data Integration and Report Generation - After the probe is removed, all collected data is integrated and analyzed to create a comprehensive mapped report of the vagina and surrounding pelvic floor structures. This report is crucial for guiding further clinical decisions.

3. Post-Procedure

Post-procedure care for transvaginal biomechanical mapping typically involves monitoring the patient for any immediate discomfort or complications following the procedure. Patients may be advised to rest and avoid strenuous activities for a short period. The results of the biomechanical mapping will be compiled into a detailed report, which will be discussed with the patient in a follow-up appointment. This report will provide insights into the condition of the pelvic floor and inform any necessary treatment plans or interventions. It is important for patients to communicate any unusual symptoms or concerns to their healthcare provider following the procedure.
