<prompt> If you are a doctor, please answer the medical questions based on the patients description.Dear Dr.My son age 10 is an ESRF patient and currently undergoing CAPD 4 times a a day with fill volume of 700mls. His latest urea is at 31 which is alarming. Was told to increase his fill volume to 800mls. I am worried sick of his urea level. Is there anyway, I could control his urea?  <response>: Hello and welcome to Chat Doctor. As a Urologist, let me advise you that, urea level of 31, isnt alarming. As you know, CAPD isnt as good as HDhemodialysis, for treatment of ESDESRFCKD. The important parameters to check, while on dialysis are urea, creatinine, sodium,potassium, uric acid, Hb, and Ioinputoutput chart. It should be checked every third to fifth day, depending on the cause of CKD. In CARD, the fluid volume is dependent on these parameters. If you send me the last reports, with scan, as a direct question, in my name, I can give you an expert opinion. Diet is very important in this stage. Chat Doctor. Manga.
