Hi I started having severe pain in my left flank around 7 years ago and kept getting told that I it was just muscular. I had my daughter last year and since then the pain got a lot worse, so in May this year was sent for an ultrasound which discovered I had hydronephrosis of the left kidney. I was referred to a urologist and sent for a ct scan, the results of the ct scan which I got last week revealed I had a staghorn struvite kidney stone and that I need to be referred for a pcnl operation to remove it. I was at Gp today as the pain is horrendous and I occasionally pass out and also vomit with the pain, and was told that the staghorn is in fact on my right kidney (which I have very little pain on) I have the hydronephrosis and a small stone on the left side, I am worried now that if I have op to remove staghorn which I know I still need, that I will still have the pain on my left side, as don't think I can cope much longer, and would you normally get all this pain with just a small stone or could it be as a result of the hydronephrosis? Really would like some information or advice or just if anyone has been through this what was the treatment. Thanks in advance
