I am a 31 year old female and I have been diagnosed with a kidney deformation called a duplicate renal pelvis. I have been to several doctors about my constant pain when urinating I always have blood in my urine and when I get stressed out I pass these things that even the urologist didn't know what they are they are stringy, fleshy, and red and white. I always have to run to the bathroom to pee. I have severe pain in my kidneys and bladder. Kidney disease runs in my family but no one can give me a definite answer to what is really wrong with me if anyone has these symptoms and has a diagnosis please let me know
