<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had an ultrasound and the results came back that I have an extra renal pelvis on the right side. Occasionally I have shooting pains in my LRQ of my abdomen and sometimes after urinating I feel like I still have to go. I have also been very bloated for months. What does all this mean?  <response>: Good Day, and thank you for being with Chat Doctor ! You have a condition called a double collecting system. It is where in two passages of urine developed in your kidney Instead of one. Most of the time it is a normal variant and doesnt cause any symptoms. But since you have post void Chat Doctor. I suggest doing a PROGRAM to check the status of your urinary system. I hope I have succeeded in providing the information you were looking for.
