dc.description.abstract | Objectives—The changes of the extracellular matrix of the connective tissue have
significantly contributed to the incidence of pelvic organ prolapse (POP). It
seems reasonable that sonoelastography could be a useful tool to evaluate the
elasticity of pelvic floor tissue in patients with POP and compare it to those
without POP. The main aim of this pilot study was to determine if there are differences in the elasticity of the levator ani muscle (LAM) and vaginal tissue
between patients with and without POP.
Methods—Prospective observation study, including 60 patients (30 with POP
and 30 without POP). Sonoelastography was performed to evaluate the elasticity
(in kilopascals, kPa) of the following regions of interest: vagina at the level of
middle third of the urethra; vagina at the level of the bladder trigone; vagina in
the anterior and posterior fornix; vagina at the level of middle third of the
anorectal canal; posterior third of the LAM.
Results—A total of 60 patients completed the study (30 with POP, 30 without
POP). In the POP group, 18/30 (60%) had an anterior vaginal wall prolapse,
3/30 (10%) a uterine prolapse, 15/30 (50%) a rectocele, and 6/30 (20%) a
enterocele. Patients with POP had higher elasticity in all anatomical study areas,
with statistically significant differences in the anterior fornix (13.6 vs 11.2 kPa;
P: .012). A multiple regression (controlling age, menopausal stage, and parity)
allowed to detect statistically significant differences in the elasticity of the middle
third of the urethra (P: .03) and the middle third of the anorectal canal
(P: .019).
Conclusion—It is possible to evaluate the elasticity of the LAM and vaginal tissue using sonoelastography, detecting a higher elasticity in patients with POP
than in those without POP. | es |
