Very low. Uterine perforation is a potential complication of placement of an iud. Once properly placed, the iud is not likely to move. Perforation rates may be as low as <1% for a very experienced physician who places iud's frequently. Ultrasound before and after placement will virtually eliminate the risk, as any improperly placed iud will be detected and can be corrected immediately.
