Epidemiologic study of bladder and urethral injury in Korea: A nationwide population-based study

Abstract

Purpose We aimed to analyze the characteristics and management of bladder and urethral injuries in Korea by use of the National Health Insurance Service (NHIS) database. Materials and Methods Data from the NHIS database representative of all cases of Korean bladder injury (n=4,631) and urethral injury (n=17,858) reported between 2012 and 2016 were analyzed. We used the International Classification of Diseases, 10th revision, clinical modification codes to identify the diagnoses. Results A total of 491 males (1.97/100,000) and 590 females (2.39/100,000) experienced bladder injury in 2012, and 449 males (1.76/100,000) and 624 females (2.47/100,000) in 2016. The risk of bladder injury was higher in female than in male (hazard ratio [HR], 1.267; p<0.001). The annual incidence of bladder injury did not increase (HR, 0.992; p=0.409). A total of 2,886 (62.3%) patients were managed with conservative treatment, and 1,745 (37.7%) patients underwent surgical treatment. A total of 4,114 males (16.5/100,000) and 285 females (1.2/100,000) had urethral injury in 2012, while 4,465 males (17.5/100,000) and 303 females (1.2/100,000) had urethral injury in 2016. The incidence of urethral injury is increasing annually (HR, 1.010; p=0.036). Conclusions The incidence of urethral injury increased continuously over the years studied, whereas that of bladder injury remained unchanged in Korea. The incidence of bladder injury was higher in females, and more than 90% of total urethral injuries were reported in males. This is the first study to evaluate the epidemiology of bladder and urethral injury using a nationwide population database.

Bladder Inflation Prior to Cesarean Section Can Prevent Bladder Injury in High Risk Patients

“…Pelvic adhesions resulting in distortion of normal anatomy are the most common risk factors for bladder injury, making dissection of the urinary bladder more challenging (Arulkumaran et al, 1986). Another Korean study reported that bladder injuries occur during hysterectomy (22%) and cesarean section (1.5%) (Tae et al, 2022). Our study showed urinary tract injuries in a few cases of group A with urinary bladder inflation just before cesarean section.…”

Fibrinogen/poly(l-lactide-co-caprolactone) copolymer scaffold: A potent adhesive material for urethral tissue regeneration in urethral injury treatment

“…Since urethral wounds are infrequent, their occurrence has already been growing due to an increase in the number of highway vehicle accidents [ 50 ]. The preponderance of urethral injuries can be caused by either blunt trauma to the abdominal (typically coupled with a pelvic fracture) or straddling damage to the pelvis [ 38 ]. Urethral injuries caused by a pelvic fracture are frequently accompanied by numerous internal injuries (bladder, spleen, liver, and colon) and a higher risk of death [ 37 , 5 ].…”

Epidemiology and Management Trend of Renal Trauma: Results of a Nationwide Population-Based Study

“…However, there are few epidemiological studies on renal trauma in Asia, including Korea. 9 In addition, there are few studies that provide epidemiological data on treatment modalities for renal trauma; however, most of these studies have been limited to small case series. Therefore, we present epidemiological data on renal trauma using the National Health Insurance Service (NHIS) database.…”
