It depends: Decreasing urine output and increasing blood creatinine levels are signs of worsening kidney function. If creatinine is close to 4, hemodialysis may be considered. Be candid with your doctor and have a serial bun, creatinine blood test. If the urine output is still good and there are no signs of heart failure or lung congestion, maintainance of adequate water intake will delay the progression.
