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.

Laparoscopic hysterectomy with adnexectomy
This video demonstrates the technique of a total laparoscopic hysterectomy with adnexectomy. Our patient is a 44-year-old lady with Tamoxifen-induced endometrial hyperplasia, which failed to respond to medical treatment.
Umbilical incision is made on the left internal border to give a more aesthetic scar.
Direct entry is performed. The assistant helps to lift the abdomen while the surgeon directs the trocar perpendicularly towards the rectus sheath first, then directs it towards the pelvis. The midline port is inserted: this should be at a slightly higher level than the lateral ports for better ergonomics. The uterine manipulator has a rotating ceramic valve for opening the vagina and a set of rings to maintain the pneumoperitoneum. The procedure is started by coagulating and cutting the round ligament on the left and opening the broad ligament. The broad ligament is opened parallel to the infundibulopelvic ligament for adnexectomy and a window is made over the grey area. The posterior leaf of the broad ligament is opened towards the left uterosacral ligament. The anterior leaf of the broad ligament is opened towards the vagina by dissecting the space and coagulating and cutting the tissues in between. The dissection is continued until the uterine artery is reached. The left infundibulopelvic ligament is coagulated and cut. The same procedure is done on the other side. Bladder dissection is performed with the help of the assistant holding up the bladder and entering the vesicovaginal space. The bladder is dissected away, beyond the valve of the manipulator. The left uterine artery is coagulated and cut. The left uterosacral ligament is coagulated and cut. The right uterine vessels are coagulated and cut followed by the uterosacral ligament. The vagina is now cut against the valve of the manipulator using a monopolar hook. Bleeding points are coagulated with a bipolar forceps. The vagina is sutured in two layers using extracorporeal knots. The procedure is now complete and hemostasis is confirmed. This patient had a favourable postoperative outcome and was discharged on postoperative day 1.

Laparoscopic resection of deep endometriotic nodule for pelvic pain, left hydronephrosis and renal function impairment
Renal function impairment is a rare condition when associated with endometriosis. This video shows the laparoscopic resection of a deep endometriotic nodule for pelvic pain, left hydronephrosis and renal function impairment. The left kidney has an almost silent pattern on scintigraphy. The therapeutic strategy consists of freeing the obstacle caused by the endometriotic nodule, placement of a double J (JJ) catheter and monitoring for renal function in the postoperative follow-up. Further laparoscopic nephrectomy is to be discussed if the renal function is not improved.
