Does the yellow fluid resulting from peritoneal dialysis invalidate ablution, and is it necessary to perform ablution for prayer after each process of introducing and expelling this fluid?

If a discharge exits the urethra while the urinary opening is uncovered, it does not invalidate ablution according to the Maliki school and the predominant view among the Shafi'is, contrary to the Hanafis. However, if the urinary opening is blocked, then ablution is nullified.
