“…The treatment of parapelvic cyst by a flexible ureteroscope has the advantages of short operation time, small surgical trauma, less intraoperative bleeding, quick postoperative recovery, short postoperative hospitalization, and so on. Most hospitals in China choose laparoscopic surgery as the first choice for treatment [ 26 , 27 ]. Internal incision and drainage of parapelvic cyst under a flexible ureteroscope is a more natural lumen approach, and there is basically no blind area, so that the location of the cyst can be more accurate [ 28 ].…”

Objective. Comparing the clinical effect of flexible ureteroscope and laparoscope in the treatment of parapelvic cyst. Method. A total of 82 patients with parapelvic cyst who underwent surgical treatment in our hospital from May 2019 to May 2020 were selected. Patients were randomly divided into a control group and an observation group; the control group underwent laparoscopic parapelvic cyst topical decompression; the observation group underwent transurethral flexible ureteroscope holmium laser incision and drainage of parapelvic cyst. The intraoperative (operative time, intraoperative blood loss, and ventilation time), postoperative (time of getting out of bed, pain score, and length of hospital stay), and recurrence were compared between the two groups. Results. (1) The operative time and intraoperative blood loss in the observation group were significantly better than those in the control group ( P < 0.05 ), while the ventilation time had no significant difference ( P > 0.05 ). (2) The pain score and length of hospital stay in the observation group were better than those in the control group ( P < 0.05 ). There was no significant difference in the time of getting out of bed ( P > 0.05 ). (3) There was no serious infection or bleeding in either group. The observation group had no recurrence, and the postoperative recurrence rate was 0. There were 11 cases of recurrence in the control group, and the postoperative recurrence rate was 26.83%. The postoperative recurrence rate of the observation group was significantly lower than that of the control group, with statistical significance ( χ 2 = 4.604 , P < 0.05 ). Conclusion. Flexible ureteroscope for the treatment of parapelvic cyst could effectively reduce the operative time, intraoperative blood loss, and pain; in addition, the postoperative recovery was fast and the recurrence is rare, which was worth popularizing.

“…Its use may mitigate the costs and burdens associated with the use of reusable flexible ureteroscopes. Preliminary work evaluating LithoVue has involved cadaveric, 6 in vitro, 7 in vivo, 8 and ex vivo porcine model studies, 9 as well as case reports 10 and one clinical feasibility study. 11 These studies revealed that LithoVue is comparable with existing conventional, reusable flexible ureteroscopes in terms of visual image quality, intraoperative maneuverability, and user satisfaction.…”

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.

“…Since the introduction of su-fURS, it has undergone an evaluation of a series of in vitro experiments. Several studies have indicated that there were no remarkable differences in image quality and deflection ability between the su-fURS and ru-fURS (28,29). Different stone locations, calyceal structures, long learning curves, and surgeon proficiency are all probable reasons.…”

Objective: This article explores the differences in the effectiveness and safety of the treatment of the upper urinary calculi between single-use flexible ureteroscope (su-fURS) and reusable flexible ureteroscope (ru-fURS).Methods: We systematically searched PubMed, Embase, Cochrane Library, Scopus database, and CNKI databases within a period from the date of database establishment to November 2020. Stata 16 was used for calculation and statistical analyses.Results: A total of 1,020 patients were included in the seven studies. The statistical differences were only found in the Clavien–Dindo grade II postoperative complication [odds ratio (OR) 0.47; 95% CI 0.23–0.98; p = 0.04]. No significant statistical differences were observed in operative time (OT), estimated blood loss (EBL), length of hospital stay (LOS), and stone-free rate (SFR).Conclusion: Our meta-analysis results demonstrate that su-fURS, compared with ru-fURS, has similar effectiveness and better security for treating upper urinary calculi.
