Presentation of four cases of keratinizing squamous metaplasia (KSM), two of the renal pelvis, one pyelocaliceal and one ureteral. Nephrouretetectomy was performed in all cases. All our patients showed good evolution. A review of the literature is made discussing all the etiological, diagnostic and therapeutical aspects of the condition. Its benign evolution is highlighted as well as the current need, once a better knowledge of the condition's natural history is available, of using a conservative approach.
报告4例角化性鳞状化生（KSM）病例，其中2例发生于肾盂，1例发生于肾盂肾盏，1例发生于输尿管。所有病例均行肾输尿管切除术。我们所有的患者病情均进展良好。本文回顾了文献，讨论了该疾病的所有病因、诊断和治疗方面。强调了其良性病程，以及一旦对该疾病的自然史有了更好的了解，目前就需要采用保守治疗方法。
