question: Sir, my son aged 22 years is suffering from kidney problem since December 2012. His Serum creatinine was suddently checked on 28th of November 2012 and was found to be 20+. He was got admitted in Sir Ganga Ram Hospital, new Delhi where he was admitted for 6 days. Since then he is taking regular dialysis in a gap of 4-5 days but his serum creatine raises very fast some time it reaches to 18, 20, 22 +++ but his blood urea remains less than 200 most of the time. As per doctors advise his water intake is around 500-600ml/day and urine outpur ranges between 90-120ml/per day. Kindly suggest proper medication.
