Summary

This study tests whether women having a planned C-section can safely skip the routine bladder catheter. Instead, they will urinate on their own just before surgery. The goal is to see if this approach avoids the need for a catheter after birth, while also improving comfort. About 550 pregnant women will take part, and researchers will compare those who urinate beforehand with those who get the standard catheter.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance: No drug; the procedure is either spontaneous urination before surgery or standard bladder catheterization during surgery.
What this could lead to: If successful, this could make planned C-sections more comfortable by avoiding routine bladder catheters, without raising the risk of needing a catheter afterward.
What could go wrong: This is a relatively small, early-stage trial (550 participants). The approach may not work for all women, and there is a risk of urinary retention requiring emergency catheterization.
