Abstract

Objectives: The aim of the study was the evaluation of repeatability and reproducibility of chosen urethral neck mobility measurements obtained during introital pelvic floor sonography performed with a 2D transvaginal probe.

Material and methods: In order to assess the repeatability and reproducibility, independent measurements on the ultra­sound image were taken by two specialists on 92 female patients at rest and at strain (Valsalva maneuver). 2D ultrasound examination was performed introitally with a transvaginal probe (PFS-TV). The location of the urethral internal orifice was defined with coordinates of two points. Point CI marks the urethral anterior edge visualized on ultrasound as closer to the pubic symphysis. Point CII marks the posterior edge visualized more peripherally from pubic symphysis.

Results: Repeatability and reproducibility measurements of point CI location and mobility were good and very good (0.6710–0.9961), while of point CII — were medium, good and very good (0.5738–0.9944). Point CI was clearly visible in all cases. It was not possible to accurately mark point CII in 4.3–17.4% of cases.

Conclusions: The possibility to visualize point CI in every single case with very good and good repeatability and reproduc­ibility of measurements of this point’s location and mobility allows the usage of CI point as a universal reference point for evaluation of bladder neck mobility and position during PFS-TV in the clinical practice and for research purposes.
