“…Two strategies may further optimize the procedure. Laser with efficient dusting property, such as TFL, will generate smaller particles and obtain higher stone clearance [ 20 , 21 ]. Smaller caliber endoscopes will bring an ideal scope-sheath ratio allows larger fragments to be aspirated out without scope withdraw, thus enhance the stone clearance [ 22 ].…”

Introduction During the last decades, the advent of flexible ureteroscopic lithotripsy has revolutionized the management of upper urinary tract stones. We designed a patented tip-bendable ureteral access sheath to facilitate stone clearance. Our current study reported our initial experience of 224 cases. Materials and methods The study is a descriptive, retrospective analysis. The initial 224 cases, operated consecutively by one surgeon during 16 months, were reviewed. The novel tip-bendable ureteral access sheath was applied in the procedure. Demographics, laboratory tests, and peri- and postoperative findings (operation duration, stone-free rate (SFR), utilization of flexible instruments and complications) were analyzed. Resutls The median age of the patients was 56 years and the mean stones size was 2.3 ± 1.3 cm. There were 63 cases of upper ureteral stone, 93cases of renal stone and 68 cases of ureteral-renal stones. The mean operative time was 69.2 ± 65.2 min. The immediate stone-free rate was 76.8% and the 1 month post-operative stone-free rate was 97.3%. Most cases(95.5%)were success in single session. Two patient experienced post-operative fever. There was no unplanned readmission. The frequency of post-operative complications was estimated at 0.89% (Clavien I). Conclusion Flexible ureteroscopic lithotripsy with tip-bendable ureteral access sheath is a safe and effective procedure, which can achieve excellent stone clearance.

“…Therefore, the higher absorption coe cient in water translates into greater stone ablation e ciency [28,29]. Studies have indicated that thulium ber lasers have better lithotripsy performance than holmium lasers, especially in terms of ablation speed, stone size, and stone displacement [30][31][32]. Studies have shown that the super-pulsed thulium ber laser is a safe and e cient lithotripsy tool with minimal intraoperative stone displacement and smaller stone fragments, regardless of stone type and hardness [32].…”

Objective To investigate the safety and feasibility of super-pulsed thulium fiber laser under transurethral flexible ureteroscopy in the treatment of parapelvic cysts combined with renal stones. Patients and methods Twelve patients with parapelvic cysts combined with renal stones admitted from October 2022 to May 2023 were treated with super-pulsed thulium fiber laser under transurethral flexible ureteroscopy and internal incision and drainage simultaneously. CT scans were performed at 1, 3, and 6 months postoperative to assess the cysts and stones, respectively. Results The mean age of the patients was 61.5 ± 7.5 years. The mean size of parapelvic cysts was 5.6 ± 0.7 cm. The mean size of the renal stones was 15.6 ± 3.2 mm. The mean CT density of all stones was 1,464.9 ± 656.5 HU. All patients underwent successful one-stage surgery without serious complications. The mean operative time was 41.2 ± 9.5 min. The average intraoperative bleeding was 6.7 ± 3.0 mL, and the average hospital stay was 2.0 ± 0.7 d. The postoperative CT reexamination indicated that the stone clearance rate was 100%, with no obvious residual stone, and the parapelvic cysts basically disappeared. Conclusion Super-pulsed thulium fiber laser under transurethral flexible ureteroscopy is a safe, feasible, and effective treatment method for parapelvic cysts combined with renal stones, with the advantages of high stone clearance rates and low intraoperative bleeding.
