Article Synopsis
  • Flexible ureterorenoscopy (fURS) is effective for treating kidney stones under 2 cm and upper urinary tract cancers, but there's limited research on which fURS provides the best image quality.
  • A study compared seven types of fURS using videos rated by 103 participants, revealing that digital ureterorenoscopes generally outperformed fiber optic ones in image quality.
  • The Storz D ureterorenoscopes, especially in Clara Chroma mode, provided the best overall image quality, with Olympus V performing notably well, while Olympus P6 and Storz X2 had lower quality ratings.

Introduction: The Spies™ system (Karl-Storz®) was introduced into digital ureteroscopy to improve endoscopic vision. To date, there is no data to either indicate which of the Spies modalities is better for improving diagnosis and treatment procedures, nor to compare the modalities in terms of image quality. The aim of this study was to evaluate and compare the image quality of five Spies™ modalities (SM) to the standard white light in an in-vitro model.

Purpose: To examine laser fiber passage capabilities through flexible ureterorenoscopes (fURSs) and to measure deflections and flow characteristics.

Methods: For this in vitro study, eight fURSs were examined (Olympus URF-P6, URF-P6, URF-V, URF-V2; Storz Xc and Flex-X2; Richard Wolf Cobra Vision; and Lithovue). Four laser fibers standard 200- and 273-μm (uncleaved and cleaved), sheath-coated and ball-tip fibers were attempted to pass through each fURS while deflected at 120°, 180°, maximum deflection, and maximum deflection with reduced 9-mm radius.

Purpose. Transitional cell carcinoma (TCC) affecting the graft after renal transplantation is a very infrequent way of presentation of this tumor. Our aim is to present our single institution experience with 2 cases, as well as to perform a review of the literature about this tumor after the transplant.
