Aims and Objective. "Postpercutaneous nephrolithotomy nephrostogram" (PPNN) is routinely performed in most of the centers. No published series could be found in the literature without post percutaneous nephrolithotomy nephrostogram. Hence, the aim of our study is to highlight that post percutaneous nephrolithotomy nephrostogram is not mandatory and it only adds to cost and morbidity without adding any information in the management of such patients. Methods. It was a prospective study from 2005 to 2012, conducted in our institute. It included 119 patients of renal stones who underwent percutaneous nephrolithotomy performed under the guidance of a single surgeon. Postoperative nephrostogram was not done in any of the patients. Results. Complete stone clearance was achieved in 97.5% of patients and 2.5% of patients needed two to three sessions of ESWL later on. None of the patients needed second look percutaneous nephrolithotomy or nephrostogram. Conclusion. Postpercutaneous nephrolithotomy nephrostogram increases chances of infection, inconvenience, contrast related complications, and cost, with no added advantage over plain X-ray KUB, and it should not be done as a routine investigation prior to the removal of PCN tube in patients with complete stone clearance.
目的。大多数中心常规进行“经皮肾镜取石术后肾造影片”（PPNN）检查。在文献中未发现没有经皮肾镜取石术后肾造影片的已发表系列研究。因此，我们研究的目的是强调经皮肾镜取石术后肾造影片并非必需，它只会增加成本和发病率，而在这类患者的管理中并未增加任何信息。方法。这是一项于2005年至2012年在我们研究所进行的前瞻性研究。研究纳入了119例肾结石患者，这些患者均在单一外科医生的指导下接受了经皮肾镜取石术。所有患者术后均未进行肾造影片检查。结果。97.5%的患者结石完全清除，2.5%的患者后来需要进行两到三次体外冲击波碎石术（ESWL）。没有患者需要二次经皮肾镜取石术或肾造影片检查。结论。经皮肾镜取石术后肾造影片会增加感染、不便、造影剂相关并发症的几率以及成本，相较于普通X线腹部平片（KUB）并无额外优势，对于结石已完全清除的患者，在拔除肾造瘘管之前不应将其作为常规检查。
