Background:
The aim of the present study was to identify prepregnancy, pregnancy and delivery correlates of urinary incontinence postpartum (PP UI) as reported by women in a cross-sectional population sample.
Methods:
A questionnaire-based cross-sectional survey was carried out in 1998 in a random population sample of 3900 20- to 59-year-old women. The present study includes 376 women who had their last delivery during 1993-96.
Results:
UI immediately after childbirth and 6 months thereafter was reported by 23.4% and 2.7%, respectively. PP UI was strongly associated with UI both before and during the present pregnancy, explaining 37.5% and 51.7% of postpartum UI, respectively. Eight percent experienced their first UI episode ever immediately after the delivery. Among women undergoing a cesarean section 8.8% reported postpartum UI, as contrasted with 24.9% in other women. Postpartum UI was positively associated with perineal suturing but un-associated with labor augmentation, episiotomy, birth weight, and breast-feeding.
Conclusion:
In the present study, which included a comprehensive causal model, postpartum UI could be explained first of all as the decline of pregnancy UI, secondly as a manifestation of a pre-existing tendency to react by UI, and finally as a consequence of the birth process itself.

The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...

Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
