Pelvic Endometriosis Causing Hydronephrosis

Study Objective Step by step narrated demonstration of ureterolysis. Design Surgical video. Setting The patient was positioned in the dorsal lithotomy position in adjustable Allen stirrups. Three port laparoscopic approach. Patients or Participants 51-year-old female who presents with left sided pelvic pain and hydronephrosis/hydroureter. Interventions The patient underwent a laparoscopic excision of endometriosis with bilateral ureterolysis. Measurements and Main Results Successful removal of endometriosis and resolution of hydroureter and pain. Conclusion Laparoscopic excision of endometriosis can be technically challenging and time consuming. A conservative approach with ureterolysis generally resolves the patient's pain. The imaging of choice in diagnosing ureteral complications of endometriosis is MRI. Cystoscopy post surgery can help assess ureteral function but does not guarantee that thermal injury has not occurred.
