Trans-vaginal tape (TVT) is seen on the axial and coronal images as linear low signal structures extending from the lower anterior abdominal wall, passing posterior to the bladder neck.
The dynamic images reveal:
- a moderate degree of global pelvic floor descent
- a moderate sized anterior rectocoele
- no rectoanal mucosal intussusception or external prolapse
- a moderate sized cystocoele and reduction of vesico-urethral angle in keeping with urethral hypermobility
The presence of the TVT reflects a previous attempt at treating the stress urinary incontinence. However there is marked descent of the urinary bladder on evacuation, and this with the change in urethral angle are anatomical changes that contribute to stress incontinence. There is also rectal descent along with a rectocoele. The imaging findings can explain all of the symptoms.
