Prevalence and severity of lower urinary tract symptoms in the third trimester of pregnancy.

INTRODUCTION AND HYPOTHESIS: Pregnancy is a risk factor for urinary disorders, mainly in the third trimester. Lower urinary tract symptoms (LUTS) are often underreported by health care professionals and significantly impact the quality of life of pregnant women. Our objective is to analyse lower urinary tract function during the third trimester of pregnancy and assess the impact of traditional risk factors for pelvic floor dysfunctions on bladder health in pregnant women.

METHODS

This is a secondary analysis of a multicentre cross-sectional study. Third-trimester pregnant women aged 18 years or older anonymously filled in the "Italian Pelvic Floor Questionnaire for pregnant and postpartum women" questionnaire, validated for pelvic floor disorders in pregnancy and postpartum.

RESULTS

A total of 927 pregnant patients completed the questionnaire. Among them, 97.3% complained of at least one urinary disorder. Frequency was the symptom reported most often (77.3%), whereas nocturnal enuresis was the least reported (17%). Despite the high prevalence of LUTS in our sample, only 13.4% reported that they negatively impact their quality of life. Overweight and obesity, advanced maternal age, smoking, family history of pelvic floor disorders and poor pelvic floor contraction capacity were confirmed to be risk factors for the onset of LUTS, even in our population.

CONCLUSIONS

Urinary symptoms are extremely common in the third trimester and significantly affect the quality of life of pregnant women. Since overweight, obesity, smoking and reduced pelvic floor contractility emerged as modifiable risk factors for the development of these symptoms, prevention and adequate counselling are cornerstones of pregnancy care.
