目的提高对肾乳头钙斑诊治效果。方法回顾总结 1991～ 1999年在手术中通过肾镜发现肾乳头钙斑诊治情况。结果肾乳头钙斑与肾乳头粘连紧密，无法取出，做病理检查，证实在肾乳头上有微小结石存在。 1例合并肾盂结石。 1例合并肾盂与输尿管移行部狭窄。 2例局部肾盏扩张。术前均表现典型肾绞痛合并血尿。 B超为典型结石影像，出现强光团、合并声影。 CT示致密阴影 ,CT值大于 300HU。结论肾乳头钙化斑与肾盏内结石术前鉴别比较困难，由于治疗方法不同，对于高度怀疑肾乳头钙斑的病例，可行输尿管肾镜检查，同时取病理。
Objective To improve the diagnosis and treatment of renal papillary calcium. Methods The diagnosis and treatment of renal papillary calcium spot by nephrolithotomy during 1991-1999 was reviewed. Results Renal papillary adhesions and renal papillary close, unable to remove, do pathological examination, confirmed that there are tiny stones in the renal papilla. 1 case with pelvic stones. One case with renal pelvis and ureteral stricture. 2 cases of local calyceal dilatation. Preoperative performance of typical renal colic with hematuria. B-as a typical image of stones, there light group, the merger of sound and shadow. CT showed dense shadow, CT value is greater than 300HU. Conclusion Calcification of renal papilloma and calyx calculus before the identification of more difficult, due to different treatment methods, for highly suspected cases of renal papillary calcification, feasible ureteroscopy, taking pathology.
