In plain words
Postpartum urinary retention is when a mother cannot empty her bladder after birth. It is defined as not being able to urinate within about six hours of a vaginal birth or of removing a urinary catheter. The bladder can fill and stretch, and that can be uncomfortable. The cause is often swelling, numbness, or pain around the birth area, or a bladder that has been emptied by a catheter during labor or surgery. A mother may feel pressure, fullness in the lower belly, or a sense that she is going but nothing comes out. Some retention is silent, so a mother may not feel the bladder fill. A provider may check the bladder with a scan or a catheter. Care is usually simple, but a bladder that stays full needs attention. Call your provider the same day if you cannot pass urine or the bladder feels very full and painful.
The deeper version
Postpartum urinary retention is defined as failure to void within 6 hours of vaginal delivery or catheter removal, with the clinical definition often combined with post-void residual volume measurement. Overt incidence is reported at about 0.5 to 2 percent of vaginal births, with silent retention more common and under-recognized. Mechanisms include perineal edema, pudendal and sacral nerve injury from or , and bladder after prolonged catheterization. Bladder scanning is the usual first measure, and intermittent catheterization is a standard step. The main controversy concerns routine post-void residual screening versus symptom-based approaches, given the variability in incidence reported across studies. NICE guidance on postnatal care (NG194, 2021) covers voiding assessment.
