“…Initially flexible ureteroscopy was used as a diagnostic tool, but Bagley and Rittenberg [2] reported the first therapeutic use of the instrument in 1986, for unsuspected large ureteral stone fragment after percutaneous nephrolithotomy. The authors performed concurrent antegrade flexible ureteroscopy following percutaneous nephrolithotomy in 8 patients.…”

“…The authors performed concurrent antegrade flexible ureteroscopy following percutaneous nephrolithotomy in 8 patients. They extracted the ureteral stone fragment with a stone basket under the visualization of flexible ureteroscope in one of them [2]. Ever since, flexible ureteroscopy has been in use increasingly for therapeutic interventions.…”

“…Later on, Bagley and Rittenberg [2], Huffman, and Lyon performed the procedure and improved the characteristics of primitive flexible ureteroscopes in the early 1980s [3]. They devel- oped the basics of current flexible ureteroscopes by adding some new novelties consisting of a working channel, an active tip deflection and altered stiffness [2,3]. In time, with the introduction of new flexible ureteroscopes and the holmium:yttrium aluminum garnet (Ho:YAG) laser, flexible ureteroscopy procedures began to be used more commonly [4].…”

Aims: We aimed to evaluate the durability and cost effectiveness of the latest digital flexible ureterescope by comparing it with the conventional fiberoptic one. Materials and Methods: Data of patients who underwent retrograde intrarenal surgery between January 2013 and December 2014 were collected. Fiberoptic Flex-X2 or digital Cobra vision flexible ureteroscopes were used for the procedures. The comparison of both ureteroscopes was performed in terms of patient and stone characteristics, operative outcomes, durability, and cost effectiveness. Results: A total of 105 patients were evaluated for the study. The patient and stone characteristics and operative outcomes were similar between the groups. Overall, 54 and 51 procedures were performed using Flex-X2 and Cobra vision, respectively, before they were sent for renovation. The purchase prices were USD 29,500 for Flex-X2 and USD 58,000 for Cobra vision. Costs of per case were determined as USD 549.29 for Flex-X2 and as USD 1,137.25 for Cobra vision. Per minute working time costs were USD 772.04 and 1,471.33 for Flex-X2 and Cobra vision respectively. Conclusions: The digital Cobra vision has high costs without any difference in durability as compared to Flex-X2. Moreover, it has no benefit over Flex-X2 in terms of surgical outcomes.

The application of the coumarin-based pulsed-dye laser has allowed the endoscopist to employ more delicate instruments with smaller working channels in treating urinary and biliary calculi. We have previously reported our first 100 patients treated with this laser. In 159 consecutive patients, 176 renal, ureteral, bladder, urethral, and biliary calculi with an average size of 1.6 cm were treated with the pulsed-dye laser in antegrade or retrograde fashion using rigid (6.9F-11.5F) or flexible (8.5-10.5F) endoscopes. The laser fibers ranged from 200 to 550 microns and the energy from 60 to 200 mJ. In some cases, the laser was used as an adjunct to percutaneous nephrolithotomy for staghorn calculi, to fragment bladder calculi without anesthesia, to free encrusted ureteral catheters, or as a lithotrite in the biliary tree. Only 4 stones (2.5%) could not be fragmented. There were no complications directly attributable to the use of laser energy. The pulsed-dye laser is safe and efficacious as an endoscopic lithotrite.
