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.
