In march doctors diagnosed me with urethral pelvic junction stenosis. I had my first stent placed on April 1, 2008 on May 8, 2008 I had a pyeloplasty to fix this upj which by the way is a birth defect. The surgery took 3 1/2 hours, and another stent was placed,the surgery was the most painfull thing I have ever had. I stayed in the Hospital for three days, I kept the stent for three months. The doctor that done my surgery was awesome. I hope I didnt scare any one with this info. I wish someone had told me.
