Materials and Methods: From the National Health Insurance Service database, we collected and analyzed data on ureteral damage in the entire South Korean population from January 2012 to December 2016. Patients with ureteral damage-related surgical codes were classified as having an iatrogenic ureteral injury; those without surgical codes associated with ureteral damage were excluded. Information on age, sex, comorbidities, and surgical codes for ureteral injury and ureteral damage treatments was collected. Results: A total of 2595 patients with iatrogenic ureteral injuries were included. The iatrogenic ureteral injury was most common in patients in their 40s (704, 27.13%), followed by those in their 50s (586, 22.58%). The most frequent comorbidity was malignancy (30.91%). The risk of ureter injury was higher in women (1489, 57.38%) than in men (1106, 42.62%) (Poisson regression; HR, 1.770; 95% CI, 1.654–1.895; P < 0.001). Of all iatrogenic ureteral injury cases, 38.19% were due to urological surgery and 61.81% were from other departments. The annual incidence of iatrogenic ureteral injury was increasing (hazard ratio, 1.092; 95% confidence interval, 1.067–1.118). Excluding urological surgeries, surgeries related to ureteral injury were the most frequent among colon surgeries (40.15%), followed by hysterectomy (22.04%) and other gynecological surgeries (18.35%). Ureteral stent indwelling (46.91%) was the most common treatment according to ureteral injury, followed by end-to-end ureteroureterostomy (19.07%). Conclusion: Using National Health Insurance Service data allowed us to apprehend the trend and treatment of iatrogenic ureteral injuries in South Korea. Our results are valuable as academic references. keywords : Incidence, Injury, Ureter
