To perform a prospective study to determine the risk factors associated with perirenal haematoma development after percutaneous renal biopsy (PRB).
This multivariate prospective study collected demographic and clinical data from all consecutive adult patients that underwent real-time ultrasound-guided PRB of native kidneys. All biopsies were performed by two well-trained ultrasound physicians using 16G biopsy needles. Routine renal ultrasounds were performed within 12-24 h after biopsies in order to observe post-biopsy perirenal haematoma formation. Patients were stratified based on the occurrence of post-biopsy haematoma development.
This prospective study enrolled 218 patients and stratified them into a haematoma group ( = 126) and a non-haematoma group ( = 92). Binary logistic regression analysis identified female patients (odds ratio [OR] 1.990; 95% confidence interval [CI] 1.125, 3.521), patients with a body mass index (BMI) ≥28 kg/m (OR 2.660; 95% CI 1.097, 6.449) and patients with immediate post-biopsy active bleeding (IPAB) (OR 2.572; 95% CI 1.422, 4.655) as being more likely to have perirenal haematoma after real-time ultrasound guided PRB of native kidneys.
Female sex, a BMI ≥28 kg/m and IPAB were risk factors for perirenal haematoma after real-time ultrasound-guided PRB of native kidneys.
进行一项前瞻性研究，以确定与经皮肾活检（PRB）后肾周血肿发展相关的危险因素。
这项多变量前瞻性研究从所有接受实时超声引导下的肾活检的连续成年患者中收集了人口统计学和临床数据。所有活检均由两名训练有素的超声医师使用 16G 活检针进行。在活检后 12-24 小时内进行常规肾脏超声检查，以观察活检后肾周血肿的形成。根据活检后血肿的发生情况对患者进行分层。
这项前瞻性研究共纳入 218 例患者，并将其分为血肿组（n=126）和非血肿组（n=92）。二项逻辑回归分析确定女性患者（比值比 [OR] 1.990；95%置信区间 [CI] 1.125, 3.521）、BMI≥28kg/m（OR 2.660；95% CI 1.097, 6.449）和即时活检后活动性出血（IPAB）（OR 2.572；95% CI 1.422, 4.655）的患者更有可能在实时超声引导下的肾活检后发生肾周血肿。
女性、BMI≥28kg/m 和 IPAB 是实时超声引导下肾活检后发生肾周血肿的危险因素。
