Abstract
Although ureteric injury is relatively uncommon, it is a serious event that can result in intra-abdominal sepsis, renal failure, and loss of the ipsilateral renal unit. Most injuries are iatrogenic and remain undiagnosed until the patient presents with symptoms postoperatively. In addition to compromising patient safety, missed ureteric injuries frequently result in litigation. Over the past 20 years, there has been a rapid uptake of laparoscopic and robotic techniques within urology and other surgical specialties. This trend, coupled with increased use of ureteroscopy, has increased the risk of injury to the ureter. The key to diagnosing and managing a ureteric injury is to have a low threshold for suspecting its presence. Diagnosis can be achieved using retrograde pyelography, ureteroscopy, CT, or intravenous urography. Initial management should involve ureteric stent placement or percutaneous nephrostomy drainage. In selected patients, surgical reconstruction might be the optimal approach. Decisions regarding surgical technique (open, laparoscopic, or robotic) are guided by the clinical situation and surgical expertise available.
Key Points
-
The close proximity of the ureters to important abdominal and pelvic structures increases the risk of iatrogenic injury; the ureter is particularly vulnerable during prolonged ureteroscopy and laparoscopically assisted vaginal hysterectomy
-
Ureteric injuries sustained in the trauma setting are often accompanied by a myriad of other serious injuries
-
The key to diagnosing and managing a ureteric injury is to have a low threshold for suspecting its presence
-
Retrograde pyelography, ureteroscopy, CT urography, and intravenous urography can be used to confirm the diagnosis
-
First-line management options include ureteric stenting and percutaneous nephrostomy drainage
-
In some cases, surgical reconstruction might be required; the use of open, laparoscopic, or robotic techniques will depend upon the clinical situation and surgical expertise
