AVA: Automated Viewability Analysis for Ureteroscopic Intrarenal Surgery

Ureteroscopic intrarenal surgery comprises the passage of a flexible ureteroscope through the ureter into the kidney and is commonly used for the treatment of kidney stones or upper tract urothelial carcinoma (UTUC). Flexible ureteroscopes (fURS) are limited by their visualization ability and fragility, which can cause missed regions during the procedure in hard-to-visualize locations and/or due to scope breakage. This contributes to a high recurrence rate for both kidney stone and UTUC patients. We introduce an automated patient-specific analysis for determining viewability in the renal collecting system using pre-operative CT scans.
