Determination of Risk Factors of Postpartum Urinary Retention (PAUR)

Determination of Risk Factors of Postpartum Urinary Retention: a Retrospective Case-control Study

Postpartum urinary retention is an uncommon complication of the vaginal delivery. Failure to diagnose it may have a real impact both on the urinary plane but also on the psychological level.

The hypothesis is that the identification of risk factors for the emergence of acute urinary retention would allow preventive management. The investigator conducted a retrospective, comparative, case-control study, including 2 groups of 96 patients who have had a vaginal delivery in the department between 2011 and 2015. The first group included patients with postpartum acute urinary retention (PAUR). The second group, control group, without PAUR, was selected randomly, respecting a 1:1 matching criteria, including the year of delivery and the age of the patient at delivery. The goal was to identify the potential risk factors of post-partum acute urinary retention in order to define a better prevention.
