✦ Synopsis
Transperineal sonography has been described as being useful in assessing patients in special clinical situations such as posterior placenta previa, preterm labor, stress incontinence, and vaginal atresia. We explored the feasibility of this approach in assessing the uterine circulation in 54 subjects, of whom 36 were postmenopausal. We found that visualization of the uterine artery by the transperineal approach was satisfactory in most patients. The uterine arterial Doppler indices obtained from this approach were compared with those obtained by the transvaginal route. Highly significant correlations were found (correlation coefficient tau for pulsatility index = 0.74, p < 0.0001). No significant differences in results between the two approaches were detected using the Wilcoxon Matched-Pairs Signed-Rank test. We conclude that transperineal Doppler studies of the uterine circulation are possible and may be useful in certain patient groups.
