Study Objective:
To evaluate the incidence and characteristics of urinary tract injury after laparoscopic-assisted vaginal hysterectomy (LAVH).
Design:
A retrospective study that evaluated all cases of urinary tract injury at the time of LAVH in an 11-year period. Parameters including surgical indication, site of injury, time of diagnosis, method of treatment, and long-term follow-up were analyzed. (Canadian Task Force classification II-2).
Setting:
Tertiary care university hospital.
Patients:
A total of 38 urinary tract injuries were found in 7725 LAVH.
Intervention:
LAVH and repair of urinary tract injuries with transvaginal or transabdominal approach.
Measurements And Main Results:
The incidence of urinary tract injury after LAVH was 4.9/1000 procedures: 3.9/1000 for urinary bladder injury and 1.0/1000 for ureteral injury. Prior cesarean section was the most common risk factor for bladder injuries. Ninety-six percent (29/30) of urinary bladder injuries were detected and treated during surgery. Half (4/8, 50%) of the ureteral injuries were identified during surgery. Of the 38 complications, 28 (75.7%) occurred in surgery.
Conclusion:
Most urinary tract injuries in LAVH were identified during surgery and are associated with the surgeon's experience. Bladder injury can be repaired either transvaginally or abdominally; ureteral injury can be repaired abdominally.
