Ureteral injuries, often from ureterorenoscopy (URS), require prompt diagnosis and treatment. Therapy for these iatrogenic injuries depends on severity, ranging from stenting for partial tears to complex reconstruction for severe damage.
Area of Science:
- Urology
- Surgical Complications
Background:
- Iatrogenic ureteral injuries account for approximately 75% of all ureteral injuries.
- Ureterorenoscopy (URS) is a common cause, despite its generally low complication rates.
- American Association for the Surgery of Trauma (AAST) grading classifies injuries from I-II (partial) to III-V (complex).
Purpose of the Study:
- To outline diagnostic and therapeutic strategies for ureteral injuries.
- To emphasize the importance of timely intervention for optimal outcomes.
- To correlate treatment modalities with injury severity.
Main Methods:
- Review of ureteral injury classification systems (AAST grades).
- Description of treatment options based on injury grade.
- Discussion of surgical reconstruction techniques.
Main Results:
- Partial ureteral injuries (Grades I-II) are managed with ureteral stents (14-21 days).
- Complex ureteral injuries (Grades III-V) may involve endoscopic ureteroureterostomy with variable long-term results.
- Surgical reconstruction using bowel segments or kidney autotransplantation are options for severe injuries.
Conclusions:
- Prompt diagnosis and treatment are crucial for managing ureteral injuries.
- Therapeutic approach must be tailored to the specific grade and location of the ureteral injury.
- While endoscopic treatments exist, complex injuries may necessitate advanced reconstructive surgery.
