Purpose of Review: To review laparoscopic surgery in the treatment options for ureteral lesions in gynaecological surgery., Recent Findings: Laparoscopic treatment of ureteral injuries has been increasingly reported over the past years. Treatment has progressively shifted from ureteroneocystostomy performed by laparotomy to less invasive treatment options such as ureteral stenting or dilatation in case of stricture, stenting under laparoscopic guidance and laparoscopic stitching of lacerations, laparoscopic ureteral reanastomosis or laparoscopic ureteroneocystostomy for transections. Deep endometriosis surgery of an associated hydronephrosis is associated with a high incidence of ureteral lesions making preoperative stenting desirable in order to facilitate the eventual repair, while avoiding the more problematic insertion of a stent after a lesion is made.The available data confirm the excellent outcome of stenting obstructive lesions. When stenting proves difficult or in case of a ureteral leakage, laparoscopic aided stenting is strongly suggested, in order to avoid further damage while permitting simultaneous repair if necessary. Laparoscopic suturing of a laceration over a stent is clearly superior to stenting only. Results of ureteral reanastomosis of a transected ureter vary from 88 to 100%; an occasional subsequent stenosis can be treated with dilatation. Bladder reimplantation has become feasible by laparoscopy and results seem promising. Laparoscopic bladder reimplantation is suggested as the method of choice in case of failure of a previous laparoscopic treatment., Summary: Data strongly support laparoscopy as the method of choice for the management of ureteral lesions.

Objective: To investigate the outcome of laparoscopic repair of ureteral injury in laparoscopic gynecologic surgery., Design: Prospective trial., Setting: University hospital., Patient(s): Forty patients with a ureteral lesion in laparoscopic surgery between 1991 and 2007., Intervention(s): Laparoscopic ureteral repair, laparoscopic-assisted or blind stent insertion., Main Outcome Measure(s): Treatment outcome of ureteral lesion analyzed by type of injury, time of diagnosis, and management., Result(s): In 4,350 consecutive laparoscopic gynecologic interventions, 42 lesions occurred, 5 during hysterectomy, 1 during adnexectomy, and 36 during deep endometriosis surgery. In the latter group (n = 1,427), the incidence was 1.5% and 21% in women without and with hydronephrosis, respectively. In eight women in whom a stent was inserted after surgery without laparoscopic guidance, five were uneventful and three needed a second intervention. In all 34 women in whom a laparoscopic repair over a stent was performed, the outcome was uneventful, whether diagnosed and treated during surgery (n = 25) or after surgery (n = 9)., Conclusion(s): Laparoscopic repair over a stent was uneventful for all lacerations, transections, and fistulas, whether performed during or after surgery, and was superior to blind stent insertion. In women with hydronephrosis and deep endometriosis, a preoperative stent insertion seems to be mandatory.

Ureter injuries are a well-known complication of gynecologic surgery and a frequent cause of medicolegal problems. Because there are no randomized, controlled trials and the available studies are small series and case reports, the evidence on which to base treatment is weak. We therefore reviewed the complete English-language literature of ureter repair since 1990. In total, 608 ureter injuries were reported. Although it is widely believed that for laceration or section the prognosis is affected by a delay in diagnosis, we could not find evidence to substantiate this. An obstruction requires stenting only. For a laceration, stenting with suturing was more effective than stenting only (p = .006). A ureter anastomosis was successful in over 94% of cases either by laparotomy or laparoscopy. In conclusion, the literature data are scanty and heterogeneous and do not permit solid conclusions. Evidence, however, is emerging that a laceration should be treated by stenting and suturing. A ureter anastomosis over a stent could become a valid option especially when performed by laparoscopy.
