Postpartum urinary retention usually lasts for 3 days and can last for a month or more if recovery is poor. If the patient’s bladder function is good and the recovery ability is relatively strong, then after the patient has postpartum urinary retention, the patient may only need to be catheterized for the first few days, and wait for the bladder function to recover, then remove the catheter, and the symptoms of urinary retention will then be improved, and the retention usually lasts for about 3 days. However, if the patient’s bladder function is low and the individual’s ability to recover is not as strong, then the duration of postpartum urinary retention may be longer, taking up to a month or even longer to pass urine normally. After the onset of postpartum urinary retention, patients should relax and avoid aggravation of the condition due to anxiety. Patients and their families can help patients to urinate by inducing urination through hot compresses, listening to the sound of water flow, etc. If acute urinary retention occurs, it is necessary to consult a doctor in time to cooperate with the doctor for catheterization treatment.
