What is Pelvic floor dyssynergia?

Pelvic floor dyssynergia or anismus is a malfunction of the external anal sphincter and puborectalis muscle.

Colonoscopy is also available if a colon check-up is required. We also offer also endorectal 3D ultrasound, very useful for studying muscular damage after episiotomy and childbirth. In selected cases, we also perform MR defecogram or proctogram, a special magnentic resonance exam performed in order to correctly evaluate pelvic floor prolapses.
