I have had my tubes tied for 5 years. done during c section. recent xray showed free fluid in cul de sac, and pelvic phleboliths. did not mention tubal ligation. is there a possibility they grew back together? i have lost 70 pounds. was 22 at tubal?

Depends on why the USD was done. The free fluid and the phleboliths can be seen occasionally and not of consequence. Sometimes it is difficult to visualize anatomical parts because of adhesions. The weight loss might have also contributed to it. The failure rate of tubal ligation is .5% and you have not gotten pregnant for 5 years.

The described X-ray would not be able to visualize your tubes or the tubal ligation, so you cannot draw any conclusion because it wasn't mentioned. Your weight loss (congratulations!) or age at tubal would not increase the risk of failure, which as previously mentioned, is quite small.
