Fused Supernumerary Kidney W/one Ureter

I am a 39 yo female with the following urinary tract abnormalities, (per several specialists): Supernumerary fused right kidney, ectopic, lies in the iliac crest and pelvis, with 2 additional renal arteries. Kidney is malrotated -anteriorly, with a single ureter draping over the kidney and then "s" curving, almost a hard 90 degrees before entering the bladder.

My problems began 4 years ago when I went to my MD with what I thought was a pulled lower back muscle on my right side. Not so, he found anomaly and sent me to specialists. In the last 4 years I have had numerous UTI's, persistent flank pain, and passed several stones. MD's are very fascinated by the anomaly but cannot find issue with the kidney. Glad for that! However, one MD relieved pain somewhat. She believed pain was neuropathic pain and I now take a small daily dose of Nortriptyline. It has helped, but....

My question is this...Can the ureter in the position it is in and it's travel to the bladder cause some of my problems such as reflux, obstruction, UTI's, and pain??
