To provide insight into the epidemiologic characteristics and trends of genitourinary (GU) self-inflicted injury (SII).
We used data from the National Trauma Databank between 2017 and 2020. We described the characteristics of GU SII cases based on injured organ and then compared male and female injuries.
We identified 56,463 patients with SII, of which 1508 (2.7%) had GU involvement. Most cases were male patients (77.3%) and white (70.6%). Median age was 35 years (IQR 26-50). The most commonly injured GU organs were kidney (43.4%), followed by scrotum/testes (22.5%), and penis (18.2%). Most cases (89.9%) represented a single-organ injury whereas 10.1% had 2 or more GU organs injured. Seventy-three of those with kidney injuries (11.2%) underwent nephrectomy. Only 1 patient performing GU SII had a diagnosis code for transsexualism but the majority (82.2%) suffered from pre-existing conditions of which 20.5% had 3 or more comorbidities. More than half the population (54.9%) had preexisting diagnosed mental or personality disorder. A non-GU co-injury was present in most cases (70.8%), most commonly affecting another abdominal organ (44.3%) or fractures (41.3%). A positive drug screen was found in 30.7% of cases. Most patients survived though 15.4% died. Ninety-four percentage of fatal cases had a concomitant non-GU injury.
GU injuries account for 2.6% of all SII. These patients are often young white males with known mental or personality disorders. Kidneys were the most common injured and mortality was highest in cases of kidney and bladder injuries with multi-organ trauma involving non-GU organs.
深入了解泌尿生殖系统（GU）自残损伤（SII）的流行病学特征和趋势。
我们使用了2017年至2020年期间国家创伤数据库的数据。我们根据受伤器官描述了GU SII病例的特征，然后比较了男性和女性的损伤情况。
我们确定了56463例SII患者，其中1508例（2.7%）涉及GU。大多数病例为男性患者（77.3%）且为白人（70.6%）。中位年龄为35岁（四分位间距26 - 50岁）。最常受伤的GU器官是肾脏（43.4%），其次是阴囊/睾丸（22.5%）和阴茎（18.2%）。大多数病例（89.9%）为单器官损伤，而10.1%的患者有2个或更多GU器官受伤。73例肾脏损伤患者（11.2%）接受了肾切除术。只有1例进行GU SII的患者有易性癖诊断编码，但大多数（82.2%）患有既往疾病，其中20.5%有3种或更多合并症。超过一半的人群（54.9%）有既往诊断的精神或人格障碍。大多数病例（70.8%）存在非GU合并损伤，最常见的是影响另一个腹部器官（44.3%）或骨折（41.3%）。30.7%的病例药物筛查呈阳性。大多数患者存活，不过15.4%死亡。94%的致命病例伴有非GU损伤。
GU损伤占所有SII的2.6%。这些患者通常是患有已知精神或人格障碍的年轻白人男性。肾脏是最常受伤的器官，在伴有涉及非GU器官的多器官创伤的肾脏和膀胱损伤病例中死亡率最高。
