Last night I was at a party with no available restroom. I had been drinking, so I had to go really bad, but I held it until I got home. I ran straight to bathroom, sat down and started to go, I went a lot at first, then suddenly without warning it completely stopped midstream. I still had the urge to urinate, and my bladder still felt very full, and I was experiencing some burning. I tried pushing but could not get a single drop out. When I wiped with the tissue I felt something hard, I was mortified to feel a kidney stone lodged in my urethra! Part of it was sticking out, I could grab it with my fingernails, but I couldn t pull it out. I spent nearly 2 hours wiggling it, pulling it, pushing it, trying to turn it but it was stuck. Finally it came out, and I was able to void my bladder, and I m feeling fine. I had no warning, I m familiar with kidney stones, I ve passed many before, the biggest bring 8mm. Those always caused me excruciating pain, but this one did not. All day I was wearing a tight corset as part of my Halloween costume, maybe I was compressed so tight I didn t feel it? I don t know. I measured my stone and it it 18mm. I always was told a stone that large would be unable to pass, so I m wondering if stones that large are common, and if people pass them without medical intervention, or am I unique??
