Results with 7.5F versus 10F rigid ureteroscopes in treatment of ureteral calculi

The effect of ureteroscope size in the treatment of ureteral stone: 15-year experience of an endoscopist

“…Use of small-calibre URS has been studied only in a few studies without any consensus in their results. [4,6,7] Yaycıoğlu et al [4] reported that duration of surgery was 57±35 min in small-calibre URS group, and 54±30 min in large-calibre URS group. Atis et al [7] found those durations as 32.7±5.8 and 30.2±5.4 min in small-calibre and large-calibre URS, respectively.…”

“…Investigations on adults reported success rates of small-calibre URS between 84-89.8% while reported success rates of large-calibre URS were between 80-85.5%. [3,4,7] Atis et al [7] compared results of 4.5F semirigid URS and 8.5F rigid URS, and reported the success rates as 88.5% and 84.6%, respectively. The results of that study indicated that there was no statistically significant difference between success rates of small-and largecalibre URS.…”

“…[16][17][18] Studies comparing URS sizes in children reported a higher JJ stent insertion rate after smallcalibre URS. [5,6,15] In adult patients, Yaycıoğlu et al [4] reported higher stenting rates after small-calibre ureteroscopy, however Atis et al [7] emphasized a reduction in postoperative rate of stent use. Kocaoğlu et al [15] reported use of stents in 42% of the patients after small-calibre URS in children.…”

“…[3][4][5][6][7] In this study, we aimed to compare stone-free rate (SFR), duration of surgery, and complication rates in a large series performed by a single endoscopist by using different-calibre URS.…”

Does Stone Entrapment With "Uro-Net" Improve Ho:YAG Laser Lithotripsy Efficiency in Percutaneous Nephrolithotomy and Cystolithopaxy?: an In Vitro Study

“…The best surgical technique and energy source to be applied differs according to stone and patient characteristics. The ability to fragment any stone composition allied to a secure profile for the urinary tract and development of small fibers suitable for flexible endoscopy led the Holmium:Yttrium--Aluminum-Garnet Laser (Ho:YAG) to become the preferred energy source for stone breakdown during ureteroscopy (URS) (2)(3)(4)(5). In contrast, intracorporeal lithotripsy during percutaneous nephrolithotomy (PCNL) and cystolithopaxy (CYS) is usually performed by ultrasonic or pneumatic devices as fragmentation and extraction can be performed with greater efficiency (6)(7)(8).…”
