Does the ablution of a patient who undergoes peritoneal dialysis become nullified?
Peritoneal dialysis is a method of treatment used in kidney failure. With this method, a catheter is placed in abdominal cavity. Abdominal cavity is filled with the dialysis fluids given patient through this catheter. Periton functions as a filter. The harmful substances and excess fluids in the blood transfer to the fluid in the abdominal cavity. With discharge of this fluid, harmful substances and excess fluids accumulated in the body are eliminated from the body.
The fluids that are injected to the abdominal cavity of the kidney patients, to whom peritoneal dialysis treatment is administered as explained above, and afterwards eliminated from body are considered as najis (ritually impure) substances in religious terms. In this respect, one should show sensitivity to avoid himself from touching this water just as he does so for urine. Discharge or coming out of the aforesaid fluid from body as explained nullify ablution as in najis (ritually impure) substances coming out from body under normal conditions. If it gets on clothes or body these parts need to be washed (Kasani, Bada’i, I, 119; Marghinani, al-Hidayah, I, 118).
