Group/Cohort Intervention/treatment
Pre/post pelvic floor surgery imaging Other: Pre/post imaging

Primary Outcome Measures :
  1. Tissue elasticity change after the surgery measured as a gradient in tactile image. Unit of measure: mmHg/mm [ Time Frame: pre-surgery and post-surgery (4-6 months after surgery) measurements ]
    Tissue elasticity is measured for entire anterior and posterior compartments

  2. Pelvic floor muscle strength change after the surgery measured as a pressure dynamic feedback during muscle contractions. Unit of measure: mmHg [ Time Frame: pre-surgery and post-surgery (4-6 months after surgery) measurements ]
    Muscle strength is measured during voluntary and involuntary muscle contractions, involuntary relaxation and Valsalva maneuver.
