Respected Sir As a medical student you might be aware that foamy urine has many causes- Phospaturia and crystalluria might also result in a foamy urine. As long as there is no proteinuria, nothing is to be worried about. Just make sure you have plenty of oral fluids daily so as to flush out the renal stone. Limit salt intake and animal protein intake. Hope this helps Get Well soon Thanks.
