Hello! I was born with a horseshoe kidney. Diagnosed at 3 years with wilms tumor. Had partial nephrectomy (removed left side). In 2001 my kidney shut down, they did a procedure saying I had scar tissue build up. Everything was fine until 2016 when it shut down again. This time they thought I had stones and placed a ureteral stent. Pulled it 1 month later and was back in the ER with my kidney shutting down again within days. It's been determined that my ureter is coming over a mass from where my kidneys were joined and it's clamping itself off. Luckily I have an apt with Mayo in May to hopefully fix this. Anyone else have this issue?
