WCE 2017: Risk of Complications with Endoscopic Renal Papillary Biopsy

Vancouver, Canada (UroToday.com) Dr. Rivera, Senior Associate Consultant from the Mayo Clinic, Rochester presents his research on the safety of papillary biopsy. The evidence concerning the safety of papillary biopsy in the study of renal stone formation is limited. 

In this study, Dr. Rivera’s group retrospectively analyzed 1448 patients that underwent percutaneous nephrolithomy and identified 190 that had a papillary biopsy. These biopsies were done to analyze the papillary architecture. In their series, patients that underwent biopsy were slightly younger and less likely to have hypertension, however there were no differences in transfusion, complication rates or post-operative renal function.

During the presentation, Dr. Rivera explained to the audience that the information that they receive from these biopsies is highly valuable. They get a better understanding of the crystallization of papilla, such as the Randall’s plaques, calcium deposits, and intraluminal ducts. They can also gauge the level of inflammation by looking at the amount of infiltrates in the specimens, and they could use these samples for genomic testing.

Dr. Rivera, concluded that renal papillary biopsy remains a safe modality in the study of stone pathogenesis.
