“…Others have demonstrated that digital scopes outperform fiber-optic scopes in terms of visual image and this difference may account for increased efficiency during cases related to procedural length. 18 While we cannot be certain of an explanation for this time difference, in looking at the effect of stone size on procedure time, these two factors were directly correlated, providing a positive control for our multivariate analysis and some confirmation that these procedure duration differences warrant further study. With regard to the difference in complication rates, the fact that the complications occurring in the control reusable scope group were not related to infection indicates that these differences were possibly reflective of the study design rather than a factor intrinsically related to the ureteroscopes themselves.…”

Objective: LithoVueÔ is a novel, single-use, digital flexible ureteroscope that was released to the US market in January 2016. There are scant data regarding its performance in humans. Procedural outcomes comparing LithoVue with reusable ureteroscopes are presented in patients undergoing ureteroscopy for upper urinary tract pathology. Patients and Methods: Clinical outcomes between two groups of patients undergoing flexible ureteroscopy for upper urinary tract pathology were analyzed. The first group underwent surgery utilizing LithoVue, and the second group used reusable fiber-optic flexible ureteroscopes. Differences in procedural outcomes, operative times, and time spent in hospital were analyzed using two-tailed t-tests and chi-squared and Fisher's exact tests. Results: One hundred fifteen cases utilizing LithoVue and 65 cases utilizing reusable ureteroscopes were included in this study. Demographics, surgical indications, stone size, location, total stone burden, composition, procedural outcomes, and complications were comparable between groups. For all cases, LithoVue procedures lasted 54.1 -25.7 minutes compared with 64.5 -37.0 minutes for reusable scope procedures ( p < 0.05) and for stone removal cases, 57.3 -25.1 vs 70.3 -36.9 minutes, respectively ( p < 0.05). Scope failure occurred in 4.4% of LithoVue cases and 7.7% of reusable cases ( p = 0.27). Conclusions: LithoVue represents a feasible alternative to reusable ureteroscopes with a low rate of scope failure comparable with reusable ureteroscopes. Its use shortens procedure duration, a finding that warrants further investigation.

“…Roboflex Avicenna provides a suitable platform that improves ergonomics significantly (total questionnaire score: 5.6 vs 31.3). After only a short introduction to the device in the training model, all seven surgeons were able to perform robot-assisted FURS safely and in a reasonable time frame compared with their own published series of classic FURS [33][34][35]. Personal series using the da Vinci device following a 2-dy-training with cadavers required significantly longer operative time (351 min vs 273 min) to perform laparoscopic radical prostatectomy [36,37].…”

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.Materials and Methods Two standardized grids and 3 stones of different composition were recorded in white light and the 5SM (Clara, Chroma, Clara+Chroma), Spectra A and B) using 4 standardized aqueous scenarios. Twelve templates were done in order to simultaneously compare the same objective in the different modalities. Six urologists, five medical students, five urology residents, and five persons not involved with urology evaluated each video on a scale of 1 (very bad) to 5 (very good).Results Comparing white light to SM, subjects scored better the quality of Clara and Clara+Chroma than white light (p=0.0139 and p<0.05) and scored worse Spectra A and B (p=0.0005 and p=0.0023)). When comparing Clara to the other SM, it was ranked equivalent to Clara+Chroma (p=0.67) and obtained a higher rank than Chroma, Spectra A and B (p<0.05, p=0.0001 and p=0.0001). In the multivariate analysis mean scores were higher among urologists.Conclusion In all analyzed scenarios, the subjects ranked Clara and Clara+Chroma as the modalities with better image quality compared to white light.
