question: history of kidney stones since the age of 13, female now 29. constistantly on a 4-5 times per week basis over the past year getting kidney cramping and pain but never enough to warrant a doctors visit. low rbc (about 40) in msu but about 30% are g1 and g3 dysmorphic (i just checked myself as in micro lab). have had scans during this time (ultra sound and xray) and all show no stone. there is a about 6cm mass off the kidney at an old nephrostomy site that has always been said to be no worry. So question is... are the dRBCs of a concern?
