Urine Culture Says No Aerobic Pyogenic Organism Grown After 48 Hrs Incubation At 37 Degree Celcius. What Does This Mean ?

Question : Hello , My Father gone through Heart bypass a month back , surgery was successfully done ( ECO shows his heart is working 45% or work more by 10% as he'll recover ) during the surgery he got some problem in his kidney as well cretanine went " 3.5 " on 23.10.2013 now it is " 2.6 " 28.10.2013 and doctors said cretanine may decreased to " 2 " and he has 5 dylasis on alternate days after his surgery ..... now all the fluid is out and no swelling is there ... The size of kidney is normal and his urine culture test says " No aerobic pyogenic organism grown after 48 hrs incubation at 37 degree celcius " what does it mean ? he is passing urine as a normal one like he's taking liquid intake upto 1.25 liters and passes around the same +/- 2% , and motion is normal as well ......... so what is the problem you noticed as per above given detail. thnx & regards XXXXX
