New Paradigms in Endometriosis Surgery of the Distal Ureter
It is estimated that 2% of endometriosis cases involve the urinary tract and that the ureter is involved in up to 30% of these cases, or 0.6% of all endometriosis cases. Increasingly, the standardization and systematization of surgical treatment of endometriosis require the surgeon to have knowledge of the surgical spaces and the ureteral and surrounding pelvic anatomy in order to carry out a cytoreductive surgery that is as possible. A thorough workup is essential for the differentiation of intrinsic or extrinsic endometriosis of the ureter. The use of the resonance imaging preoperatively and ureteroscopy intraoperatively is now considered indispensable. The decision and choice of the best technique will be guided by the diagnosis (intrinsic or extrinsic), the location of the lesions, the length of the involved segment (greater or less than 3 cm), vitality of the ureter stumps, and anastomosis without tension. The main alternatives are ureterolysis and dilatation with balloon catheter which is performed for extrinsic endometriosis more than 85% of the time and ureterectomy for intrinsic endometriosis. To perform the reconstruction, the techniques with end-to-end anastomosis with the distal ureter stump or uretero-vesical reimplantation are used. Increasingly, with better knowledge of the distal ureter anatomy, easier access through laparoscopy and in contradiction to the current recommendations, we are verifying that the end-to-end anastomosis has become the preferred option or procedure of choice for ureteral reconstruction, with ureterovesical reimplantation the second option.
