I can't imagine. I've heard they are incredibly painful to pass.
I can't help chiming in here since it happened to me so recently. Here is what my Dr said. The "pain" you always hear about with kidney stones isn't in the actual passing of it. You could pass one and not even know it. Before it gets dislodged and sent out you have these bouts of back pain plus the general urinary tract irritative symptoms.
Maybe Lawman can corroborate this.
