新型自动负压式活检枪在老年肾脏疾病中的应用

Use of a new type of automatic negative pressure biopsy gun in elderly patients with renal diseases

目的探讨一种新型自动负压式活检枪应用于老年肾穿刺活检的成功率及其安全性。方法应用自动负压式活检枪进行老年肾穿刺活检301例。其中男性207例，女性94例，60岁-65岁154例，66岁～70岁83例，71岁～75岁46例，76岁。80岁17例，〉80岁l例。平均年龄66.3岁。结果肾穿刺活检301例，成功率97．3％，标本平均长度（14．4±7.3）mm，标本平均宽度（0．99±0．34）mm，光镜下肾小球平均数为（18．7±11．6）个。术后并发症肉眼血尿发生率2．0％，肾周血肿发生率29．2％。未发生需要输血、肾动脉栓塞等严重并发症。结论自动负压式活检枪应用于老年肾穿刺活检，具有简便易行、成功率高、并发症少等优点。

Objective To investigate the success rate and safety of a new type of automatic negative pressure biopsy gun for elderly renal biopsy. Methods A total of 301 cases of elderly renal biopsy were performed with automatic negative pressure biopsy gun, involving 207 males and 94 females. 154 subjects aged between 60 and 65 years, 83 between 66 and 70, 46 between 71 and 75, 17 between 76 and 80, and 1 above 80 years. The mean age was 66.3 years. Results There were 301 cases of renal biopsy, and the success rate was 97.3%. The average length of specimens was （14.4±7.3） ram, and the average width of specimens was （0.99±0.34） mm. The average number of glomeruli under light microscope was （18.7±11.6）. The incidences of the postoperative complications, the macroscopic hematuria and perirenal hematoma were 2.0% and 29.2% , respectively. No serious complications such as the need for blood transfusion and renal artery embolization occurred. Conclusion The automatic negative pressure biopsy gun for the elderly renal biopsy favors for simple operation, high success rate, and less complications.
