我科自1993年12月至1996年12月,采用新型负压肾穿装置行单人操作肾活检56例,体会介绍如下。资料与方法 1.临床资料:男37例,女19例,年龄25～58岁。其中原发性肾小球肾炎27例,狼疮性肾炎16例,蛋白尿待查5例,血尿待查2例,糖尿病肾病2例,急性肾功能衰竭1例,慢性肾功能衰竭3例。 2.装置:选用南京军区福州总医院肾脏病科研制的新型负压肾穿装置,由双峰外磨肾穿刺针及半自动肾穿负压器组成,在B超引导下穿刺。 3.方法:患者体位、清毒、铺中、局麻、测皮肾距与一般肾活检相同。在超声引导下,从穿刺点缓缓进针至肾包膜外,拔出针芯,装上内芯。接上负压器,术者右手握穿刺针,左手持负压器。令患者摒气,暂停呼吸,在B超引导下快速将肾穿刺针刺人肾脏,与此同时,左手按负压器开关使之瞬间形成负压,随即拔出肾穿刺针,操作结束。结果1.成功率:一次穿刺成功41例,占74.4%,二次穿刺成功9例,占15.6%,三次4例,占7.1%,该
Our department from December 1993 to December 1996, the use of a new type of negative pressure renal perfusion device single-operated renal biopsy 56 cases, the experience described below. Materials and Methods 1. Clinical data: 37 males and 19 females, aged 25 to 58 years. Including 27 cases of primary glomerulonephritis, 16 cases of lupus nephritis, proteinuria pending investigation in 5 cases, 2 cases of hematuria to be investigated, 2 cases of diabetic nephropathy, acute renal failure in 1 case, 3 cases of chronic renal failure. 2. Device: Selection of Fuzhou General Hospital of Nanjing Military Region, Department of Nephrology developed a new type of negative pressure renal wear device, by the double-peak external grinding kidney needle and semi-automatic renal wear negative pressure device, under the guidance of B-puncture. 3. Methods: Patient position, detoxification, shop, local anesthesia, measuring kidney and general renal biopsy the same. Under the guidance of ultrasound, the needle slowly from the puncture point to the renal capsule, pull out the needle core, fitted with the core. Connect the negative pressure device, the surgeon holds the puncture needle in the right hand and the negative pressure device in the left hand. So that patients with gas, breathing is suspended in the B-guided renal puncture quickly under the guidance of the kidneys, at the same time, the left hand by the negative pressure switch so that the moment the formation of negative pressure, then pull out the renal puncture needle, the operation ended. Success rate: a successful puncture in 41 cases, accounting for 74.4%, 9 cases of successful secondary puncture, accounting for 15.6%, three times in 4 cases, accounting for 7.1% of the
