研究目的:

前列腺电切术后静脉血栓栓塞是影响患者预后的重要并发症。在临床实践中,对于出血风险较高的患者,机械预防是被推荐的干预措施,但目前仍缺少高质量证据支持,采用机械预防的获益尚未被明确量化。本研究旨在通过真实世界数据,评估术后采用机械预防对比无任何专项预防对于前列腺电切术后患者VTE预防的有效性、安全性及经济效益,为临床决策提供关键证据。  

Objectives of Study:

Venous thromboembolism (VTE) after transurethral resection of the prostate (TURP) is an important complication that affects patient prognosis. In clinical practice, mechanical prophylaxis is recommended for patients with a higher risk of bleeding, but there is still a lack of high-quality evidence to support it, and the benefits of using mechanical prophylaxis have not been clearly quantified. This study aims to evaluate the effectiveness, safety, and cost-effectiveness of mechanical prophylaxis versus no specific prophylaxis for VTE prevention in patients after TURP through real-world data, providing key evidence for clinical decision-making.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.于2017年1月1日至2025年6月30日期间,在我院泌尿外科住院。 2.年龄 ≥ 18岁。 3.主要诊断为良性前列腺增生。 4.接受了经尿道前列腺电切术。

Inclusion criteria

1. Admitted to the urology department of our hospital from January 1, 2017 to June 30, 2025. 2. Age >= 18 years old. 3. The main diagnosis is benign prostatic hyperplasia. 4. Underwent transurethral resection of the prostate.

排除标准:

1.术前已确诊VTE(深静脉血栓或肺栓塞)。 2.因前列腺癌等恶性肿瘤行手术。 3.围手术期因其他指征(如心房颤动、机械瓣膜术后等)需要长期治疗性抗凝。 4.病历资料严重缺失,无法获取关键变量(如预防措施、结局事件等)。 5.术后因非VTE原因(如严重出血、心脑血管意外)导致住院时间显著延长(如 > 14天),因其VTE风险与常规患者不可比。

Exclusion criteria:

1. Preoperatively diagnosed with VTE (deep vein thrombosis or pulmonary embolism). 2. Undergoing surgery due to malignant tumors such as prostate cancer. 3. Requiring long-term therapeutic anticoagulation during the perioperative period for other indications (such as atrial fibrillation, post-mechanical valve surgery, etc.). 4. Severe deficiency of medical records, making it impossible to obtain key variables (such as preventive measures, outcome events, etc.). 5. Postoperative hospital stay significantly prolonged (> 14 days) due to non-VTE reasons (such as severe bleeding, cardiovascular and cerebrovascular accidents), as their VTE risk is not comparable to that of regular patients.
