Dialysis duration linked to bladder shrinkage in kidney patients
NCT ID NCT07570771
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looks at how long a person has been on dialysis and how much urine they still make affects bladder size and flexibility. Researchers will measure bladder function in 87 adults with kidney failure who are waiting for a transplant. The goal is to find bladder problems early to improve transplant success.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could help doctors better prepare kidney transplant patients by identifying bladder problems early, potentially reducing post-transplant complications.
- What could go wrong
- This is an observational study, not a treatment trial. It only measures bladder function and does not test any new therapy, so it cannot directly improve patient outcomes.
