Causes of postoperative urinary retention:

Postoperative urinary retention may be caused by anesthetic factors, surgical factors, infection factors, etc.

1. Anesthetic factors such

as spinal anesthesia, subarachnoid anesthesia, etc. may inhibit and affect the urination center, resulting in urinary retention.

2. Surgical factors

The operation itself may damage the efferent nerve of urination reflex, pelvic nerve, or cause bladder sphincter reflex spasm or urethral inflammation edema, resulting in urinary retention.

3. Infection factors

Infection at the wound site after surgery may be accompanied by severe pain symptoms, affecting abdominal muscle and diaphragm contraction, unable to produce high intra-abdominal pressure to assist urination, resulting in postoperative urinary retention.

It is recommended that patients with urinary retention after surgery should promptly inform the doctor and implement targeted treatment measures with the help of professional doctors.
