Sometimes after back surgery, people may notice changes in their ability to control urine. This can happen if the nerves in the lower back that help the bladder work are disturbed. Doctors call this Failed Back Surgery Syndrome (FBSS), which means pain or nerve symptoms continue even after surgery.
Why does this happen?
Nerve involvement: The nerves in your lower back also control the bladder. If they are injured, compressed, or irritated during or after surgery, bladder control can be affected.
Communication issues: The brain may not send or receive the right signals to your bladder after surgery.
Cauda Equina Syndrome: In rare but serious cases, nerves at the bottom of the spine get badly squeezed, causing sudden bladder or bowel problems. This is a medical emergency.
How common is it?
Studies show that bladder problems like urgency, leakage, or difficulty passing urine can affect about 4 out of 10 people after certain spine surgeries. The risk is higher when surgery is done in the lower back.
What symptoms should you watch for?
π Leakage or loss of bladder control
π Trouble starting urine or sudden strong urge
π Not feeling urine pass as usual
π Complete blockage (unable to urinate)
π Sudden numbness in the inner thighs or around the genitals
π Severe back pain with the above symptoms (seek emergency help immediately)
Can it be managed?
Yes. Treatments may include:
✅️ Pelvic floor exercises and physiotherapy
✅️ Lifestyle changes (diet, fluid timing, weight management)
✅️ Medications to relax or strengthen bladder control
✅️ Scheduled bathroom visits
✅️ In some cases, additional surgery for nerve stimulation maybe required.
Remember
Bladder problems after back surgery can be worrying, but you are not alone. With the right medical care and early attention, many people improve. If symptoms appear suddenly with pain or numbness, treat it as an emergency and seek immediate help.
