Pelvic floor diseases (PFD) often affect the adult population, with approximately 50 percent of women aged 50 years and older suffering from PFD. The condition has complex symptoms that may lead to stress and a negative impact on the quality of life. The USA spends about USD 1 billion annually on inpatient costs as a result of more than 700,000 emergency department visits and 50,000 hospitalizations associated with PFD. Defecography is currently the most commonly used method of diagnostic imaging used to evaluate PFD. This technology is not available in the Republic of Kazakhstan, despite its high diagnostic value.

In order to assess the clinical effectiveness of defecography, we have conducted a literature search in the MEDLINE database. We selected articles with pairwise comparisons of defecography with other tests: anorectal manometry; balloon expulsion test; electromyography; magnetic resonance imaging (MRI); and, ultrasound.

The findings are primarily based on two meta-analysis (91 studies representing 10,768 cases). The results have been evaluated according to the detection frequency and omission of the following signs: cystocele, middle compartment descent, rectocele, intussusception, rectal prolapse, enterocele, and perineal descent. The literature review did not reveal significant difference in diagnostic value between MR defecography and defecography based on X-ray. However, the imaging endpoints (detection rate of structural and functional abnormalities) for defecography based on X-ray were significantly better than plain radiography.

The defecography is currently considered the gold standard and the most commonly used tool of diagnosis. The implementation does not require an expensive equipment purchase (MR defecography) and is reproducible on conventional X-ray equipment if the necessary inventory is available.
