- Description
- The advantage of the impedance planimetric technique is to more readily define reproducible values for dynamic rectal compliance and elasticity, where conventional proctometrographic (pressure/volume) curves have proven less accurate. The real-time ultrasonographic measurement of rectal cross-sectional areas (CSA) during distension (and deflation) is less reliant on the intrinsic compliance characteristics of the balloon assembly or on inherent rectal geometry. In this sense, impedance planimetry provides a better reflection of rectal wall stiffness and altered viscoelastic properties during inflation/deflation cycles.
