Bottom Line: Significant impairment of vascularity was observed in multiparous patients as compared to iparous and was reflected by increased values of RImix (p < 0.001) and PImix (p < 0.001), and decreased values of Vmix (p < 0.001), Amix (p < 0.001), Imix (p < 0.001) in axial and midsagittal sections of the midurethra.A significant decrease of mean value ± SD of Imix- from 0.02 ± 0.02 in iparous to 0.005 ± 0.01 in multiparous was observed.Compared to continent iparous women, continent multiparous women demonstrated a significant reduction in the vascularity parameters in all measured variables when parity was accounted for.

ABSTRACT

Objectives: To assess the urethral vascularity in continent women using colour doppler high frequency endovaginal ultrasonography (EVUS).

Methods: We recruited 61 continent women attending gynaecology clinics between July and October 2009. Exclusion criteria included symptoms of urinary incontinence, voiding dysfunction, pelvic organ prolapse or urinary tract infection. The participants underwent EVUS using high frequency (9-12 MHz) biplane transducer (type 8848 BK Medical), according to a standardised protocol. Colour Doppler US was performed in sagittal plane and in transverse plane at the level of the mid-urethra. Ten seconds video files were recorded and following vascular parameters: flow velocity (Vmix), area of the vessels (Amix), intensity of vascularity (Imix), pulsatility index (PImix) and resistance index (RImix) was evaluated.

Results: There were 30 iparous (49.2%) women and 31 multiparous women (50.8%) with a mean (±SD) age of 32 (±4) and 46 (±6) years respectively. Significant impairment of vascularity was observed in multiparous patients as compared to iparous and was reflected by increased values of RImix (p < 0.001) and PImix (p < 0.001), and decreased values of Vmix (p < 0.001), Amix (p < 0.001), Imix (p < 0.001) in axial and midsagittal sections of the midurethra. A significant decrease of mean value ± SD of Imix- from 0.02 ± 0.02 in iparous to 0.005 ± 0.01 in multiparous was observed. Cronbach alpha, used to assess vascular correlations and parity demonstrated a reduction when expressed only for vascular parameters, indicating that number of deliveries is an important factor while assessing urethral vascularity.

Conclusions: Compared to continent iparous women, continent multiparous women demonstrated a significant reduction in the vascularity parameters in all measured variables when parity was accounted for.

Advances in knowledge: This study provides the basis for further research in assessing urethral vascularity in women.

The graphs presenting differences in values of RImixbetween iparous and multiparous patients measured in the axial section of the midurethra. Majority of multiparous patients showed the value of RI mix equal 1, while in iparous its values were more diverse, ranging from 0.5-1.

Mentions: A comparison between iparous and multiparous was made and statistically significant differences were assumed at p <0.05. A significant reduction of vascularity was seen in axial and midsagittal sections of the midurethra of multiparous women as reflected by increased values of RImix [Figure 3] and PImix (p < 0.005 and p < 0.001 respectively) and decreased values of Vmix, Amix, Imix (Table 2). Impaired vascularity is demonstrated by the significant reduction of the mean value (SD) of Imix from 0.02 (0.02) in iparous to 0.005 (0.01) in multiparous women [Figure 4].Figure 3
