After spinal cord injury, if you cannot void urine, decide the voiding method with the doctor; do not leave an indwelling catheter unmanaged long term; check kidneys and bladder on a lifelong schedule

After spinal cord injury, if you cannot void, the bladder must be emptied by catheterization or similar means. In UK data spanning seventy years, over one-tenth of deaths were in the genitourinary system. People with long-term indwelling catheters had about twice the complication rate of those on timed self-catheterization. Whatever the method, kidneys and bladder need lifelong scheduled checks.

Cost

Self intermittent catheterization four to six times a day, a few minutes each time; catheters must be bought ongoing. Rechecks every one to two years, urology or rehab. The hard part is doing it every day for decades.

Benefit

Two UK spinal cord injury centres reviewed 5483 people with traumatic spinal cord injury. They were injured from 1943 to 2010, all survived the first year after injury, and were followed to the end of 2014. 2322 died; 2170 had reliable causes of death. Leading causes were respiratory 29.3%, circulatory 26.7%, cancer 13.9%, genitourinary 11.5%. After age adjustment, genitourinary mortality was higher than in the general population; it has fallen over the years but remains elevated. Another U.S. study reviewed records of 316 people with traumatic spinal cord injury, mean follow-up 18.3 years after injury, grouped by voiding method. Complication rates: long-term transurethral indwelling catheter 53.5%, clean intermittent catheterization 27.2%, spontaneous voiding 32.4%, suprapubic cystostomy 44.4%. Complications included infection, stones, urethral injury, and imaging abnormalities. This was a chart comparison only, not randomized. The 2026 European Association of Urology guidelines state that transurethral indwelling catheters have many complications and high urinary-tract infection risk — avoid them when possible. Suprapubic cystostomy is similar, only milder. The guidelines also state that long-term follow-up is lifelong, to check upper-tract damage and risk of kidney failure. Recheck intervals in most cases are no longer than one to two years. High-risk people roughly get ultrasound about every half year, and annual physical exam and urine tests. Section 3.4.2.e of the guidelines states that intermittent catheterization and indwelling catheters are both standard for people who cannot empty the bladder, and recommends joint decision by doctor and patient. In people with spinal cord injury, quality-of-life scores on intermittent catheterization are worse than on indwelling catheters, especially with more than 4 urinary-tract infections a year. In one observational study, 42.1% of people on intermittent catheterization stopped within 12 months, mainly for inconvenience, leakage, and more infections. The guidelines state silicone catheters are better because they scale less, and latex allergy is common in neurological disease. Section 3.5.1 lists the most common UTI signals in these patients: fever, new or worse leakage, worse spasms, fatigue, cloudy urine with stronger odour, flank or bladder pain, and autonomic dysreflexia

Notes

Contested: the same guidelines list intermittent catheterization and indwelling catheters both as standard, and require doctor and patient to decide together. In people with spinal cord injury, quality-of-life scores on intermittent catheterization are worse, especially with more than 4 urinary-tract infections a year. Over four-tenths of people on intermittent catheterization stopped within a year. So if the hands are limited and no one at home can help, an indwelling catheter can be a reasonable choice — the author’s inference from the points above. For indwelling catheters, the guidelines prefer silicone. Do not decide alone, and do not leave a catheter in for years without rechecks. New leakage, cloudy foul urine, worse spasms, or fever may be a urinary-tract infection — get seen. An overfull bladder can trigger autonomic dysreflexia — see item 1 of this section (sudden severe headache). The Chinese neurogenic-bladder guideline text was not obtained and is not cited. The beneficiary is you.
