<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have noticed a strange skin growth around the urinary tract. What could be the reason for it?  <response>: It seems like you are suffering from Urethral valves, which are thin flaps of tissue that form in the urethra and can cause a blockage. They can also lead to urine back up in the kidneys and eventually cause kidney damage.
