    I have a 7mm stone on my right kidney. I had a stent placed in my 24th week of pregnancy. I’m now on my 30th week. My urologist has not mentioned it being replaced at 6 weeks. The plan was to wait until after childbirth for the stent to be removed. Should I have the stent changed every 6 weeks??

    I had a stent placed 6 months ago for kidney stone removal. It was supposed to be removed in 30 days. However, it got delayed and has been in place since 6 months. Is it dangerous now to remove it?

      Stent is placed in ureter to facilitate easy passage of stone from the kidney. Its removal has been delayed. Talk to your doctor as early as possible. Your doctor will remove it. Regarding the damage, your doctor will be the right person to tell your more about it.
