Detrusor underactivity in symptomatic anterior pelvic organ prolapse.

Introduction: The aim of this study was to assess the detrusor underactivity (DUA) prevalence of females with symptomatic anterior pelvic organ prolapse (POP) and to evaluate the relationship between DUA and POP stage.

Material and methods: This was a prospective study recruiting women with symptomatic anterior POP. Patients with symptomatic stage 2-4 POP quantification system (POP-Q) who underwent urodynamics (UD) between January 2018 and April 2021 were included.

Results: Data on 330 women (mean age 63.7 ±18.4 years old) with anterior vaginal wall defect were enrolled. Concomitant apical defect (uterine/vaginal vault) requiring surgical correction was diagnosed in 38 women (11.5%). DUA was found in 166 females (50.3%). In DUA women, POP-Q stage 2 was found in 45.2%, stage 3 in 50.9% and stage 4 in 76.5%. Only stage POP-Q stage 4 showed a statistically significant difference between DUA and non-DUA females (p 0.006).

Conclusions: In women with symptomatic POP, regardless of the POP-Q stage, the chance of DUA occurrence was high. DUA was diagnosed in approximately half of the women undergoing UD for symptomatic POP, and it was three-fold higher in cases of POP-Q stage 4. Due to the high incidence of DUA in POP-Q 4 stage, it may be advantageous to identify and treat prolapse before they progress to stage 4.
