We report a case of transitional cell carcinoma (TCC) discovered within a calyceal diverticulum at the time of percutaneous nephrolithotomy. The stones and tumor were endoscopically removed and the diverticular cavity fulgurated. Pathologic analysis demonstrated low-grade TCC. A subsequent laparoscopic radical nephroureterectomy was performed and high-grade TCC invading the parenchyma was found. This case demonstrates the potential for TCC to develop in stone-containing calyceal diverticula and also the potential for coexistence of different grades of TCC within the involved renal unit.
我们报告一例在经皮肾镜取石术时发现的肾盂憩室内移行细胞癌（TCC）病例。通过内镜切除结石和肿瘤，并对憩室腔进行电灼。病理分析显示为低级别TCC。随后进行了腹腔镜根治性肾输尿管切除术，发现存在侵犯实质的高级别TCC。该病例表明含结石的肾盂憩室有发生TCC的可能，且在受累肾单位内不同级别的TCC可能并存。
