Maruf M, et al. - Researchers reported perioperative transfusion rates, risk factors for transfusion, and outcomes from a high-volume exstrophy center in primary bladder closure of classic bladder exstrophy (CBE) (a major operation that occasionally requires intraoperative or postoperative (within 72 hours) blood transfusions) patients. Perioperative blood transfusions were received by more than half of CBE patients undergoing primary closure at a single institution. While, transfusions and osteotomy, delayed primary closure, larger diastasis, increased operative time, and increased length of stay were correlated, the odds of receiving a transfusion on multivariate analysis were independently increased with only the use of pelvic osteotomy, higher EBL-to-weight ratio, and recent year of closure.
