Abstract:
Objective To afford an new effective imaging technique for the morphological observation of the normal male pelvic floor by observing the normal male puborectalis with transrectal ultrasound and magnetic resonance imaging (MRI). Methods Thirty-six normal males were examined by transrectal ultrasound and MRI,data of puborectalis were recorded and compared including starting point, end point,appearance, structure, thickness and the relationship with peripheral organs. Results The results including the appearance,direction and internal echo of puborectalis and the relationship with peripheral organs can be clearly displayed by transrectal ultrasound compared with MRI. The thickness of right and left puborectalis at rest measured in ultrasound and in MRI were (6.22±0.57)mm, (6.19±0.59) mm, (6.20±0.61) mm and (6.17±0.53) mm, respectively. The thickness by two methods and two sides had no significant differences (P>0.05). The thickness of puborectalis measured by two methods did not correlate with age,height,body weight,the volume of prostate and interspinal diameter respectively. Conclusions Transrectal ultrasound is a new imaging method to observe male puborectalis. Identification for nomal puborectalis sonography is the foundation of diagnosis pelvic floor disease.
