hello and welcome to healthcare forum.
In rhabdomyolysis myoglobin
is released from the affected muscle leading to tubular obstruction in kidney
Initial aggressive volume loading followed by mannitol-alkaline diuresis of up to 8 litres per day is required till the myoglobin is no longer detected it urine and serum creatinine
comes to normal.
I hope i have answered your query.
Best wishes for your and your family's health.
