To compare the outcomes of using Ultrathin semirigid retrograde ureteroscopy and antegrade flexible ureteroscopy to treat proximal ureteric stones of sizes 1-2 cm. A prospective randomized multicenter study included patients who had proximal ureteric stones 1-2 cm, amenable for ureteroscopy and laser lithotripsy between August 2023 and February 2024. Two hundred thirty patients were divided evenly into two treatment groups. Group I included patients treated with antegrade flexible ureteroscopy and holmium laser stone fragmentation, and Group II included patients treated with retrograde ultrathin semirigid ureteroscopy
For upper ureteral stone, semirigid ureteroscopy or flexible ureteroscopy? Strengths and weaknesses. Flexible and semirigid ureteroscopy are two often used modalities in treating for upper ureteral stone. How about the outcome of each procedure? A retrospective cohort study among 167 patients who underwent flexible or semirigid ureteroscopic lithotripsy was performed. The pre-, intra -, postoperative and one-year follow-up outcomes were taken into comparison. Significantly higher instant stone-clearance rate (81.3% vs. 92.4%, p = .032) and less operative time (62.1 ± 27.6 min vs. 44.1 ± 24.6 min, p<.001) were found in semirigid ureteroscopy. However, the stone-clearance rate at one month (90.7% vs. 93.5%, p = .500) was similar. Baseline characteristics including patient demographics, stone
Evaluation of ultrathin semirigid ureteroscopy in terms of efficiency and cost compared to flexible ureteroscopy in treating proximal ureteric stones: a prospective randomized multicenter study. To investigate the outcome and cost-effectiveness of ultrathin 6-7.5-Fr semirigid ureteroscopy in treating proximal ureteric stones compared to flexible ureteroscopy. Two hundred and twenty patients with a solitary proximal ureteric stone were eligible for ureteroscopy (stone size = 1-2 cm). Patients were randomly subdivided into two groups: Group I included 105 patients who underwent ultrathin semirigid ureteroscopy and group II included 115 patients who underwent flexible ureteroscopy. Both groups were compared regarding successful stone access, operation time, reoperation rates, the financial cost

Effects of Ciprofol and Propofol General Anesthesia on Postoperative Recovery Quality in Patients Undergoing Ureteroscopy: A Randomized, Controlled, Double-Blind Clinical Trial. This study compares postoperative recovery quality between Ciprofol and Propofol, providing a reference for the clinical application of anesthetics. We randomized 112 patients undergoing ureteroscopic surgery into two ). The incidence of urinary tract symptoms on POD1 was lower in Group C (P = 0.043). There were no significant differences in time to spontaneous breathing recovery, extubation, recovery room stay, time to first ambulation, hospital stay, patient satisfaction, or other adverse events. Ciprofol provides comparable early postoperative recovery to Propofol during ureteroscopy and may be a preferable alternative
Ureteral Tissue Temperature During Ureteroscopy with Ho:YAG Laser Activation in an In Vivo Porcine Model. To measure temperature of the outer ureteral wall and calculate thermal dose with different irrigation and laser power settings during ureteroscopy in a porcine in vivo model. The ureters of two porcine subjects were exposed through laparotomy incisions. A length of PFA tubing, with equally suprathreshold thermal doses within ureteral tissue. Employing a 50% operator duty cycle at these same settings decreased thermal dose below threshold. Thermal dose did not reach the threshold of thermal injury in any trials with 40 ml/min irrigation. Ureteroscopy in a porcine model with commonly used irrigation rates and laser settings can elevate ureteral temperatures and produce thermal doses above

Factors Affecting Holmium Laser Efficiency: Comparison of Laryngeal Mask Airway and Endotracheal Intubation During Ureteroscopy for Renal Stones. Holmium laser lithotripsy is a standard energy source used for treatment of kidney stones during flexible ureteroscopy. Efficiency of laser surgery may be affected by patient and operator characteristics or perioperative management. Here, we sought significantly higher mean LE in patients with no postoperative complications (76.3%) compared to those with any grade (I-V) Clavien-Dindo complication within 30 days after surgery (70.0%) ( < 0.05). Flexible ureteroscopy and laser lithotripsy cases with higher LE are associated with lower rates of postoperative complications. The data also support the use of ETT over LMA to improve overall LE; however
Evaluation of Inflammatory Parameters Following Extracorporeal Shock Wave Lithotripsy (ESWL) and Ureteroscopy for the Treatment of Proximal Ureteral Stones. Introduction Inflammation can arise as a consequence of both extracorporeal shock wave lithotripsy (ESWL) and ureteroscopy (URS) treatments. Alterations in inflammatory parameters may serve as indicators of kidney injuries and the ensuing
Recent advances in the treatment of renal stones using flexible ureteroscopys. Upper urinary tract stones are a common urological disease that can be treated by flexible ureteroscopy (FURS) through the natural urinary tract, in addition to extracorporeal shock wave lithotripsy (ESWL) and percutaneous nephrolithotomy (PCNL). The advantages of FURS are less trauma, faster recovery, and fewer for FURS is broadening, positioning it as a potential primary choice for urolithiasis treatment in the future. This review outlines the progress in employing flexible ureteroscopy for the treatment of renal calculi in order to generate insights for further research.
