67 years male parkinson patients suffers from urine infection. admitted at icu. crp186, wbc22000, urea 116, creatinine 3.5. sugar normal. should he survive?

Impossible to say: Depends on a great many other things. His risk of mortality is much higher than, say, the 19 year old female with a uti, but without knowing his response and his vitals (and even with knowing these), it is impossible to answer "should he survive" or even give a hard percentage.

High creatinine : It sounds as if he is very sick and with sepsis. If he has an acute elevation of his creatinine (c), that lessens his chances of survival, as he would be in acute renal failure. The good news is that with appropriate antibiotics, good nursing and medical care he may overcome his infection and leave the hospital. Good luck.

Pyelonephritis: Often with acute sepsis the creatinine is elevated because of diminished circulating blood volume due either to decreased intake or third-spacing of liquids. This should respond to antibiotics and supportive care with fluid replacement, assuming nothing else is going on. If the creatinine remains high very long he may be a candidate for end-stage renal failure care. Discuss with his doctors.
