kidney stones

Natasha
Question... so a little back story, I'm prone to kidney stones, that being said last weekend I went to the ER and Sunday I had a stent put in. The doctor thinks the stone is too big to pass and will get bigger as the pregnancy moves forward because of the prenatal vitamins. I am 20 weeks pregnant so I will have the stent in until after I deliver. The stent is so there is no obstruction or backflow if urine so I don't get anymore infections. He will not laser it because there is a chance of miscarriage. My question is has this happened to anyone else? And any advice would be much appreciated!
