Can Drinking Coconut Water Help Kidneys When You Have Chronic Kidney Disease?

Check with your doctor. The only potential hazard would be the extremely high level of potassium found in coconut water.   Damaged kidneys do not regulate potassium levels as well as healthy ones.   Drinking large amounts of coconut water could raise your serum potassium levels to a dangerous level and cause multiple problems, up to and including severe cardiac issues.

Yes coconut water is very beneficial in cleansing the urinary tract

If you have chronic kidney disease you should talk with your doctor before even thinking about trying any type of home remedy.  It could well cause you more problems than you have now by interfering or reacting with one of your current medications.  Never try to self medicate.  This sounds safe enough but only your physician can tell you how your body will react to coconut water since he is the one who knows just exactly where you are in the area of kidney failure.  You certainly do not want to stress your kidneys any more than they are  currently.
