Hi, welcome to Chat Doctor. You are one of the rare few who has provided all the important details! I suspect you are a healthcare worker yourself. You are right in that your sister needs to see a nephrologist (not urologist) ASAP. She needs to have a 24 hour urine protein estimation and possibly a renal biopsy for diagnosis. The two differential diagnosis here are IGA Nephropathy and Post Infectious Glomerulonephritis. Only a biopsy can differentiate the two or clarify if the problem is something totally different. I am very wary of doctors treating empirically with steroids without proper diagnosis. We can prognosticate only if we have a biopsy confirmed result. However, if the proteinuria has settled already, we are in a dilemma whether to biopsy or not?? Don't waste time and see a nephrologist pronto. I don't know who is near you at Varanasi, you will have to find out. Feel free to come back with anymore queries. Best wishes.
