Laparoscopic ureteral anastomosis in a patient with hydronephrosis due to a severe endometriosis

Ureteral endometriosis is unfrequent and it is defined by the presence of endometrial glands in the ureteric or pre-ureteric tissue. The prevalence reported is less than 1% and usually confined to the lower one-third of the left ureter. This pathology generates a ureteral stenosis, with an extrinsic compression of the ureteral wall by the inflammatory response and fibrosis, or an intrinsic stenosis with the invasion of the uro-epithelium and submucosal layer of the ureteral wall. We present a short video describing the technique of the laparoscopic segmental ureteral resection followed by the re-anastomosis.
