She taken scan on 18 sep 2019. Report is 3 mm stone in left and right kidney. Post void residual urine 29 cc what is the meaning and reason? Urine routine results are all normal. Yesterday my mother consultant gynecologist doctor. I'm asked doctor to prescribe to my mother urine culture. But she told that not necessary. Because urine routine is normal so does not need. She prescribed to my mother onabet - b cream night and morning and urispas 2 per day 5 days. She told me no infection on vaginal area. And all report are normal so don't worry about it. Urine culture is need or not? Please tell me what about scan report? Please answer urology department please answer it.
