MRI DEFECOGRAM
Protocol:
Dynamic imaging of pelvic floor was done in sagittal plane using T2W sequences during rest, squeezing, straining and defecation.
OBSERVATIONS:
Pelvic floor imaging:
At rest: The anorectal junction is abnormally low ( 44mm below the pubococcygeal line). Anal sphincter is closed without leakage of endorectal material. Ano-rectal angle measures 1090.
The positions of the bladder base normal and noted above the pubococcygeal line.
During squeezing: The ano-rectal angle closes to 95 degree on squeezing. The anorectal junction remains abnormally low (49mm).
During straining: Further medium descent of the rectum noted. No obvious descent of the urinary bladder.
During defecation: There is further descent of anorectal junction. There is also mild descent of urinary bladder neck below pubococcygeal line. No significant rectocele.
IMPRESSION: MR Defecogram Study reveals:
Moderate prolapse of posterior compartment (Rectal) and mild prolapse of the anterior compartment (urinary bladder).
