Evaluating The Female Pelvic Floor Dysfunction By 3d And 4d-Ct Imaging Using 640-Multislice Ct (640-Msct)

The female stress urinary incontinence (FSUI) and pelvic organ prolapsed (POP) are a common problem for adult female. To explore the possibility of using 640-Multislice CT (640-MSCT) in diagnosing the FSUI and POP, we recruited 62 FSUI patients (SUI group), 36 POP patients (POP group) and 50 healthy female volunteers (control group) to do the pelvis scan by 640-MSCT. All the volunteers and patients had been scanned in the period of pre-voiding, voiding and post-voiding, then 3D and 4D images were reconstructed from 640-MSCT scanning images and reviewed by two radiologists. By observing these images, we measured and compared the pubococcygeal line (PCL), H line, M line, length from PCL to bladder neck(PCL-BN)and cervix (PCL-C), urethral inclined angle (UIA) and poster urethrovesical angle (PUVA) in every period. We compared the results of volunteers With the results of patients (SUI patients and POP patients). The differences in ago fertility and BMI between experiment groups and control group are no statistical significance (P > 0.05). The results showed that, in each group, H line and M line have statistical differences in pre-voiding, voiding and post-voiding (P < 0.01, P < 0.05). PCL-BN and PCL-C are decreased when voiding in each group. Some candidates in SUI and POP group, the PCL-BN is below the bladder neck before voiding, and it is getting worse when voiding hardly. PCL-C decreased significantly in the POP group when voiding. UlA and PUVA in control group have statistical differences with these in SUI group and POP group when voiding. From our results, we concluded that it is a sensitive and specific method to diagnose the SUI and POP according to 3D and 4D CT images using 640-MSCT.
