The effect of a full bladder on labor.

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine

Background:

• A distended bladder is a common occurrence during labor.
• Potential effects of bladder volume on uterine activity and labor progression are not fully understood.

Purpose of the Study:

• To investigate the impact of a full bladder on uterine activity and labor progress during normal established labor.

Main Methods:

• Studied 20 patients in established labor with a full bladder (≥300 ml) and 10 controls.
• Measured uterine activity using Montevideo units.
• Assessed labor progress via partogram before and after bladder catheterization.

Main Results:

• Uterine activity showed a modest increase post-catheterization.
• No statistically significant alteration in the labor progress slope (partogram) was observed.

Conclusions:

• A full bladder does not appear to impede the course of normal established labor.
• Clinical interventions to manage bladder volume during labor may not be necessary for labor progression.
