Figure 1. Fibre-optic versus digital ureteroscopic images.

Figure 1

Images of the renal papilla acquired using a,b | a fibre-optic ureteroscope (KARL STORZ FLEX-X2, KARL STORZ, Tuttlingen, Germany) and c,d | a digital ureteroscope (ACMI/Olympus Invisio DUR-D, Gyrus ACMI, Massachusetts, USA) The enhanced view provided by the digital scope allows superior visualization of the papilla including both an attached stone as well as nascent mineral which might ultimately become a stone or be related to stone formation. The ability to identify such details opens new doors to study associations between papillary appearance and stone disease23. Reproduced with permission obtained from Elsevier Ltd © Humphreys, M.
