由于使用防止损伤血管的肾脏切口技术,术中细致的放射学诊断,肾盂肾盏的整复和轻柔的肾实质的缝合,使肾脏结石手术的疗效得到明显改善。先决条件是要一个无血的手术野。但在常温下肾缺血超过20分钟时,便会发生肾脏缺血性损害。另外,要在较短的时间内,完成复杂的肾实质切开手术,就不得不对手术细节有所忽视,这就要求通过局部降温来提高肾脏对缺血的耐受性。在缺血时间不超过60分钟时,可使用甘露醇和次黄嘌呤核甙(Inosin)替代。
Due to the use of renal incision techniques to prevent blood vessel damage, detailed radiological diagnosis during operation, reconstructive pyelonephritis and gentle suture of renal parenchyma, the curative effect of kidney stone surgery has been significantly improved. The precondition is to have a bloodless surgical field. However, renal ischemia at room temperature more than 20 minutes, will occur renal ischemic damage. In addition, in a relatively short period of time, to complete a complex renal parenchyma incision, you have to ignore the details of the operation, which requires that by local cooling to improve renal tolerance to ischemia. In the ischemic time does not exceed 60 minutes, the use of mannitol and inosin instead.
