Urethral length measurement in women during sonographic urethrocystography - an analysis of repeatability and reproducibility.

Wlaźlak E, Kociszewski J, Suzin J, Dresler M, Surkont G - J Ultrason (2016)

Bottom Line: The Intraclass Correlation Coefficient for repeatability and reproducibility of urethral length measurements in sonographic urethrocystography ranged between 0.9217 and 0.9873 (p = 0.0000).Very good repeatability and reproducibility of urethral length findings during sonographic urethrocystography performed in accordance with the presented technique support the possible use of this type of examination in both clinical practice and research.Abstract available from the publisher.

ABSTRACT

Unlabelled: There has been a rise in the use of sonographic urethrocystography in patients with a full bladder. So far, no publications have been made on the analysis of repeatability and reproducibility of the measurements performed during this procedure.

Aim: An assessment of repeatability and reproducibility of urethral length measurements during sonographic urethrocystography in females with a full bladder in the introital approach, using real-time two-dimensional transvaginal ultrasound.

Material and methods: The ultrasound was performed in accordance with a standardized technique in female patients with a full bladder containing 200-300 mL of liquid. A total of 92 patients were included in the analysis.

Results: The Intraclass Correlation Coefficient for repeatability and reproducibility of urethral length measurements in sonographic urethrocystography ranged between 0.9217 and 0.9873 (p = 0.0000). The analysis of ultrasound urethral length measurements taken by two different physicians at an interval of several months confirmed their very high compatibility (ICC = 0.81, p = 0.000).

Conclusions: Very good repeatability and reproducibility of urethral length findings during sonographic urethrocystography performed in accordance with the presented technique support the possible use of this type of examination in both clinical practice and research.

Figure 0001: The technique of urethral length measurements during introital sonographic urethrocystography using a transvaginal probe(17)

Mentions: The sonographic urethrocystography was performed using the introital approach, in accordance with a standardized technique developed by Kociszewski, in female patients with a bladder filling of 200–300 mL. A high-frequency transvaginal probe (6.5 MHz, beam angle160°) was used for the evaluation. The test was performed in a patient in a gynecological chair in a semi-sitting position. The probe was placed near the external urethral ostium, with minimal probe compression on the investigated surface, in line with the axis of the patient. One of the images showed the pubic symphysis, which was the only constant reference point, the urethra and the bladder neck; the urethral length was measured (Fig. 1). The ultrasonographic measurement of the urethral length was performed along its long axis in the hypoechoic area of the urethra. The distance between points A and B was measured (Fig. 1). An ultrasound image of the internal urethral orifice into the bladder was selected as point A, while the point B was set in the most peripheral part inside the hypoechoic area of the urethra.
