The results of in situ dissolution of a cystine calculus is described. This approach was attempted in a female patient for whom surgery was not considered to be the best therapeutic option.
An obstructive cystine calculus was treated by in situ litholysis using N-acetylcysteine applied locally via two percutaneous nephrostomies and adjuvant oral metaphylaxis. The patient had a long clinical history of lithiasis that had also required surgery and a family history of cystinuria.
In situ litholysis completely dissolved the cystine calculus and avoided the need for a complex surgery. The procedure and a pharmacological analysis are presented.
In our view, this procedure is practical, carries minimal morbidity and should be considered in the management of cystine calculus.
描述胱氨酸结石原位溶解的结果。一名女性患者被认为手术并非最佳治疗选择，遂尝试了这种方法。
通过经皮肾造瘘术局部应用N-乙酰半胱氨酸进行原位溶石治疗阻塞性胱氨酸结石，并辅以口服预防性药物。该患者有长期的结石病史，此前也曾接受过手术治疗，且有胱氨酸尿症家族史。
原位溶石完全溶解了胱氨酸结石，避免了复杂的手术。介绍了该手术过程及药理学分析。
我们认为，该手术切实可行，发病率极低，在胱氨酸结石的治疗中应予以考虑。
