Girls, I have such a problem. Three times I took a urine test and there were leukocytes. The first time there were also erythrocytes, some residues, protein, today's showed only leukocytes. But I also took a smear and it was clean according to the results. Nothing bothers me in terms of health, but these leukocytes are puzzling. The doctor prescribed Kanefron, I've been taking it for 4 days. Maybe someone had this without any problems? And I can't understand anything, and the doctor doesn't even say how high they are, asked, said +1. I don't understand anything, help me figure it out.
