感染性结石指由持续性或复发性尿路感染引起的尿石。通常指分解尿素细菌感染而形成的磷酸镁铵(鸟粪石)和磷酸钙(磷灰石)结石。感染石的治疗历来是一个棘手的问题。因尿路感染难以根除,加之结石既多又大,常是充填肾盂肾盏的鹿角状结石,单凭手术难以治愈。虽是ESWL广泛开展的今天,其疗效仍难令人满意。数十年来,各国研究者致力于病因及溶石的研究,尽管尚无令人嘱目的突破,但已积累了众多的经验。随着泌尿腔内手术的推广和ESWL的应用,综合疗法治愈感染石已有了可能。现将感染石某些基础研究及溶石的现状作一介绍,供同道们参考。
Infectious stones are uroliths caused by persistent or recurrent urinary tract infections. Usually refers to the decomposition of urea bacterial infection and the formation of ammonium magnesium phosphate (struvite) and calcium phosphate (apatite) stones. The treatment of infected stone has always been a thorny problem. Due to urinary tract infection is difficult to eradicate, combined with stones are both large and large, often filled with pyelonephrosis calyx calculi, it is difficult to cure alone surgery. Although ESWL is widely implemented today, its efficacy is still unsatisfactory. For decades, researchers from all countries have devoted themselves to the study of etiology and dissolved limestone. Although there are no known breakthroughs, they have accumulated a great deal of experience. With the promotion of urinary surgery and the application of ESWL, synthetic therapy to cure infected stone has been possible. Now some of the basic research of infected stone and the status quo an introduction for the fellow Taoist reference.
