Purpose. Functional MRI of the pelvic floor allowes mapping and definition
of different forms of pelvic floor dysfunction.
Methods. We performed functional MRT of the pelvic floor in 39 healthy null
iparas and 324 patients. The diagnosis of a pathological organ descent was
made if certain landmarks of the pelvic floor compartments descended below
the pubococcygeal reference-line (PC-line).
Results. If there was no organ descent below the PC-line on straining and i
f the pelvic floor muscles hardly changed position,a normal finding was dia
gnosed. 70% of organ prolapses came in the combined form. The generally gra
dual development of an organ descent led to a change of the main finding in
21,6%. The masking of a cystocele (48,6%) or of an enterocele (34,3%) by a
rectocele was most frequent in these cases.
Discussion. The use of functional MRI of the pelvic floor appears to be esp
ecially useful in young patients, in cases of divergent clinical and sonogr
aphic or radiological findings and if the presence of a predominant hernial
sac with or without enterocele/rectocele is supposed.
