A system for anal and/or stomal irrigation of a users bowel comprises a reservoir (102) for an irrigating liquid, a catheter (100) for insertion into the rectum and/or stoma of a user and for expelling of the irrigating liquid from a catheter tip, and an expandable retention element (104), such as a balloon, for fixation of the catheter tip within the users rectum or stoma. Tubing and valve systems provide conduits for the irrigating liquid between the reservoir and the catheter and between the reservoir and the expandable retention element, a pump (101) being provided within the tubing system. The pump and the valve system is controllable to selectively pump the irrigating liquid into the expandable retention element, transfer the irrigating liquid through the catheter for expelling of the irrigating fluid from the catheter tip and into the users rectum or stoma, and to withdraw the irrigating liquid from the retention element for purging thereof.
