Endometriosis affected only the left ureter in 56.7% of patients, only the right ureter in 33.3%, and both ureters in 6.7%. Involvement of the ipsilateral ovary was confirmed in 64.3%. The most frequent location of UE was 1–3 cm above the UVJ (46.7%). A psoas hitch was performed in 7 patients (23.3%), and the Boari flap was used in 9 patients (30%). Hysterectomy was performed in 12 patients (40%), and 6 of them had a concomitant bilateral salpingo-oophorectomy (20%). In addition, 3 patients (10%) underwent partial bowel resection, and 2 patients (6.7%) underwent partial bladder resection. After surgery, 24 of 27 patients (80.0%) were free of sever hydronephrosis after surgery. Hydronephrosis recurred in a single patient (3.3%), but the grade of hydronephrosis improved significantly after surgery (P < 0.001). At 6 months of follow up, 4 patients (13.3%) experienced urinary tract infections and 2 patients (6.7%) reported dysuria. Patients reported a regression of dysmenorrhea symptoms (P < 0.001).\nConclusion\nThis study shows that ureteroneocystostomy provides good results in terms of relapses and symptom control in patients with ureteral endometriosis.\nSimilar content being viewed by others\nReferences\nVercellini P, Viganò P, Somigliana E, Fedele L (2014) Endometriosis: pathogenesis and treatment.
