Bisacodyl Oral for Lowering Dysfunction (of Tenckhoff Catheter)

Doctors need to insert catheter for patients who are going to have peritoneal dialysis. These peritoneal catheters can be obstructed or blocked afterward. The chance of not having smooth flow can be up to 12 and 31%. So far, constipation is one of the proposed reasons. Therefore, the study is aimed to investigate whether the preventive use of laxative before the surgery can help better improve the function of the catheter and hence better flow.
