It won't cause simple bleeding streak in urine.You can do Gram's staining, culture and sensitivity from the urine.Once the report is available you can start the treatment accordingly.I will be happy to answer your further concern, you can ask me on bit.ly/DrArun. Thank you.Dr Arun TankInfectious diseases specialist. </s>
