There is not enough details for me to say with certainty what happen in your case. Post -infection(abscess) and Hematoma are common post-op complications. Sometimes differentiating between the two when they occur can be challenging. The fact you were haveing recurrent post-op fevers as late as day 3 is suspect for an infectious cause. Posterior pelvic wall hematomas occlude the urinary tract if they spread and become large enough. Abscesss and Hematomas can be incised and drained if warranted. It is not uncommon that when this treat option is utilized, drains will be placed. I hope this helps.
Thank you for responding to me, nobody seems to want to answer me. I am still (now almost a month later) having pain during urination (the pain is in my abdomen). I had a new ultrasound done Friday to see how big the hematoma is now, but I am concerned both about the pain during urination and about the fact that there is no more drainage happening vaginally of the hematoma. Should I be concerned? If you could spare some more of your time to help me, I would greatly appreciate it.
