Hypothesis
Can incomplete renal tubular acidosis lead to calcium phosphate stones in a patient with a neuropathic bladder?
Conclusion
Abdominal spasms may indicate calcium phosphate stones in the bladder of spinal cord injury patients, and dietary changes could help prevent recurrence.
Supporting Evidence
- The patient developed bladder stones thirteen years after spinal cord injury.
- The major component of the stones was calcium phosphate, with no magnesium ammonium phosphate present.
- The patient failed to acidify urine below a pH of 5.3, indicating incomplete renal tubular acidosis type 1.
Takeaway
A man with a spinal cord injury kept getting bladder stones, and doctors found that changing his diet might help stop them from coming back.
Methodology
The patient underwent biochemical analysis of stones and urine acidification tests after taking furosemide and fludrocortisone.
Limitations
The study is based on a single case report, limiting generalizability.
Participant Demographics
A Caucasian male, born in 1943, with a history of spinal cord injury.
