Deep infiltrating endometriosis affecting the urinary tract-surgical treatment and fertility outcomes in 2004-2013.

Abstract

Urinary tract endometriosis (UTE) is a rare form of deep infiltrating endometriosis. We studied the operative treatment of UTE and evaluated postoperative recurrences and fertility outcomes. This is a retrospective cohort study of 53 women who underwent operative treatment for UTE in 2004–2013 at Helsinki University Hospital, and were followed-up until the end of 2014. The data were gathered from the hospital’s electronic database. The main outcome measures were complications, reoperations, postoperative pregnancies, and deliveries. Preoperative diagnosis was accurate in 72 % with bladder endometriosis and in 93 % with ureteral disease. Thirty-one (58 %) of the 53 operations were performed via laparoscopy. Postoperative complications requiring re-intervention occurred in five cases (9 %). Five reoperations were performed in four cases due to endometriosis recurrence, only two due to recurrence of UTE (4 %). Twenty-eight women wished for pregnancy; 18 (64 %) of them conceived. Infertility treatment was needed in 20 (71 %) cases. Twelve (75 %) women delivered via cesarean section; intraoperative difficulties occurred in ten (83 %). The complication rate with UTE operations is acceptable and recurrences are rare. Infertility is common, but 57 % of those who wished for a child succeeded. A majority of the deliveries involved unplanned and complicated cesarean section.
