泌尿系结石的发病率及复发率甚高,用化学溶解法治疗结石是属于腔内泌尿学的一种非手术治疗方法。通过适当物质的化学作用,相对不易溶解的结石矿盐可转变为水溶性,由冲洗而排除。虽然在体外,结石很易用酸溶解,但在体内应用时有一定困难。溶液不仅需要快速溶解结石,而且也需要为病人所耐受,对组织刺激性小,且不引起组织损伤。 1924年Crowell首先报告用红汞逆行冲洗肾盂,成功地使胱胺酸结石溶解。20年后,Suby及Albright通过手术时置放的肾盂造瘘管进行冲洗,溶
The incidence of urolithiasis and the high recurrence rate, the use of chemical dissolution of stones is a non-surgical treatment of endoscopic urology. Through the chemical effect of appropriate substances, the relatively insoluble stones and minerals can be transformed into water-soluble, rinsed and excluded. Although in vitro, stones are easy to dissolve with acid, but there are some difficulties in the application of the body. The solution not only requires rapid dissolution of the stone, but also needs to be tolerated by the patient, less irritating to the tissue, and does not cause tissue damage. In 1924 Crowell first reported retrograde flushing of the renal pelvis with Mercury, successfully dissolving cystine stones. Twenty years later, Suby and Albright were flushed through a pyelic fistula placed during surgery and dissolved
