[Endoscopic papillary abnormalities and urinary stone recognition (EPSR): How and why?]

The purpose of this article is to present the endoscopic papillary abnormalities and stone recognition (EPSR) to state-certified nurses (IDE and IBODE) working in the operating room.

This article is based on a literature review and the author's experience concerning the endoscopic papillary abnormalities and stone recognition.

Since the advent of minimally invasive surgery and the laser, stones are no longer sent as one piece to laboratories, but fragmented. This has made it more difficult for biologists to fully analyze the stones, because they have less morphological data than before. Therefore, endoscopic papillary abnormalities and stone recognition have positioned themselves as tools that can compensate for this loss of information. They play a pivotal role in the identification of the lithogenesis cause, and thus allow a recurrence risk reduction of stones.

Endoscopic papillary abnormalities and stone recognition are recent tools that require learning. However, the benefit of their uses is proven and is necessary for a complete management of urolithiasis.
