“…LithoVue is a digital scope, and while performance characteristics between fiber-optic and digital ureteroscopes are similar, differences may exist in image quality, flexion, and durability. 25,26 Therefore, our results may be most applicable for institutions and surgeons currently using fiber-optic ureteroscopes rather than reusable digital ureteroscopes. Moreover, the control cohort utilized repaired scopes rather than newly purchased ones, and we were unable to ascertain the number of repairs or prior uses for each scope at study initiation.…”

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.

“…In any of the semirigid and flexible ureteroscopic procedures, an increase in the renal pelvic pressure may occur through irrigation. The increased renal pelvic pressure can lead to infec-tious complications due to intrarenal, pyelovenous and pyelolymphatic backflow (21). To decrease the pelvic pressure, the use of UAS has been suggested, as well as irrigation with isoproterenol and limiting the operative time (22,23).…”

Purpose: The aim of the study was to evaluate the efficacy and safety of bilateral single--session retrograde intrarenal surgery in the treatment of bilateral renal stones. Materials and Methods: From December 2008 to February 2012, 42 patients who had undergone bilateral single-session retrograde intrarenal surgery (RIRS) and laser lithotripsy were included in the study. The procedures were performed in the lithotomy position on an endoscopy table under general anesthesia, beginning on the side in which the stone size was smaller. Plain abdominal radiography, intravenous urograms (IVU), renal ultrasonography (USG) and / or non-contrast tomography (CT) scans were conducted for all patients. The success rate was defined as patients who were stone-free or only had residual fragment less than 4 mm. Results: A total of 42 patients (28 male, 14 female) with a mean age 39.2 ± 14.2 were included in the present study. The mean stone size was 24.09 ± 6.37 mm with a mean operative time of 51.08 ± 15.22 minutes. The stone-free rates (SFR) were 92.8% and 97.6% after the first and second procedures, respectively. The average hospital stay was 1.37 ± 0.72 days. In two patients (4.7%), minor complications (Clavien I or II) were observed, whereas no major complications (Clavien III-V) or blood transfusions were noted in the studied group. Conclusions: Bilateral single-session RIRS and laser lithotripsy can be performed safely and effectively with a high success rate and low complication rate in patients with bilateral renal stones.

“…Although there is much debate on whether stent insertion should be performed in every case of straightforward intracorporeal lithotripsy, this is a common practice in our department. In this series, in particular, stenting was deemed essential also to facilitate alleviation of the high intrapelvic pressure, which inevitably occurs during ureteroscopy causing intrarenal backflow and potentially infectious complications [14]. Generally, routine insertion of a JJ stent to avoid postoperative complications is advocated in the presence of various parameters, such as prolonged operating time, large stones, impacted stones causing oedema of the ureteric wall, narrowed ureteric segments, ignored small caliceal calculi and recent urinary tract infection [15].…”

Is There a Difference in Outcomes Between Digital and Fiberoptic Flexible Ureterorenoscopy Procedures?

Abstract: Although the DFU have more limited maneuverability, comparable success rates can be achieved with both conventional and digital instruments. On the other hand, the DFU significantly reduced the operative time compared with the conventional one.
