“…7 Fallah Karkan et al in their study about the clinical potency of the Ho: YAG laser on ureteral stones, based on its fiber caliber, concluded that all 3 types of laser caliber (200 Mm, 365 Mm, and 500 Mm fibers) had great efficacy in stone fragmentation, however; by increasing the laser caliber, the stone-free rate would significantly increase. 8 By working with the photo-thermal mechanism, Ho: YAG laser can fragment stones into the crater and small pieces, thus; the risk of upward migration of stone Out patient 20 22…”

Introduction: Ureteral stones are among the most common disorders in the urologic field. Miniaturization of endoscopic devices in urology and extracorporeal shock wave lithotripsy (ESWL) has revolutionized the management of ureteral stones. The aim of this study was to compare the efficacy and results of laser versus pneumatic lithotripsy (PL) with semi-rigid ureteroscope in a randomized prospective clinical trial in removing stones. Methods: 117 adult patients underwent transurethral lithotripsy (TUL) in a single academic center and by a single surgeon. The patients were randomized in 2 groups: In group 1, 58 patients with ureteral stones underwent ureteroscopy and stone fragmentation was done by Ho: YAG laser lithotripsy (LL) and in group 2, 59 patients underwent PL (Swiss LithoClast) by using the same ureteroscope. Results: Mean age was 41.77 years and 41.1years in group one and 2 respectively (P = 0.79), there was no significant difference in male to female ratio and mean stone in both groups. The success rate for stone clearance was 79.31% and 77.96% in group 1 and 2 respectively (P = 0.52). No difference between complications was seen in both groups, but the duration of operations was different (significantly lower in group 2). Conclusion: In both techniques, acceptable results were achieved. We have found a significant statistical difference in duration of operation between our results (P = 0.001) and similar studies, while this was shorter in the pneumatic group in our study, it was longer in other similar ones. This might be a result of more experience in working with PL in our center.

“…4 There is a variety of modalities for stone fragmentation including ultrasonic, electrohydraulic, pneumatic lithotripsy (PL) or laser lithotripsy (LL). 5 A number of lasers have been trialed for the LL method, that the holmium: yttrium-aluminum-garnet (Ho: YAG) was the most commonly used treatment. 6 Ho: YAG laser which mostly applied in stone fragmentation procedure is a pulsed mode modality with 2100 wavelength (nm) and ≈0.5 mm tissue penetration characteristics.…”

versus laser lithotripsy for ureteral stones. AbstractIntroduction: Several different modalities are available for ureteral stone fragmentation. From them pneumatic and holmium: yttrium-aluminum-garnet (Ho: YAG) lithotripsy have supportive outcomes. In this study we studied 250 subjects who had ureteroscopic pneumatic lithotripsy (PL) or laser lithotripsy (LL). Methods: Two-hundred fifty patients with ureteral stones underwent ureteroscopic lithotripsy (115 subjects in the PL group, 135 subjects in the LL group) from August 2010 to April 2016. The purpose of this investigation was to evaluate stone-free rate (SFR), mean operation time (MOT), mean hospital stay (MHS), stone migration and complications. Results: Two groups were similar in age, gender, mean size of stones, side of stone, and complications. There was a statistical difference in terms of SFR, stone migration and MHS in favor of the LL group (P ≤ 0.05, P ≤ 0.05 respectively), and MOT in favor of the PL group (P ≤ 0.05). Conclusion: Both the PL and LL techniques were effective and safe for ureteral stones, however a slightly higher SFR was found in the LL group.

“…6,7 Nowadays due to the development of small equipment associated with entrance of laser science to medicine, using laser for management of urolithiasis is a good choice. 8,9 Likewise, because of small size of urethra in children, transurethral approach for bladder calculi lithotripsy by laser becomes popular among urologists and some studies showed its safety and efficacy, however more data are still needed. 6,10 The purpose of this survey was to compare the results of surgical bladder stone management in our single tertiary center.…”

Introduction: Bladder stone is more common in developing countries and it is one of the rare diseases affecting children. In recent years, there is an increasing tendency in urologists to have minimal invasive approaches. The aim of this study was to compare the results of surgical bladder stone management in our single tertiary center. Methods: From 159 children younger than 18 years with vesical stones treated during January 2000 to January 2015 in Shohada-e-Tajrish hospital, Tehran, Iran, 146 subjects entered to the study. According to type of intervention, patients stratified to three groups. First group included 80 patients that open cystolithotomy (OCL) was done for them, second group was 39 patients who underwent percutaneous cystolithotomy (PCCL) and third group was 27 patients who treated by transurethral cystolithotripsy with holmium-YAG laser (TULL). Demographic data, hospital stay, operation time, and post operation complications were recorded and comparison were drawn between the three groups. Results: Mean age was 8.3 ± 5.1 years (8.6 ± 5.1, 6 ± 4.2 years for boys and girls, respectively). Mean stone size (MSS) was 2.76 ± 1.07 cm and no significant differences were found between the three groups but it was larger in OCL group. Mean operative time (MOT) was 29.15 ± 7.12 minutes in separate; MOT in TULL was significantly higher than PCCL and OCL respectively (36.3 ± 5.97, 30.54 ± 5.27 and 26.06 ± 6.32 minutes/P = 0.000). Mean hospital stay (MHS) in OCL group was 3.55 ± 1 days that was higher than PCCL and TULL groups significantly (P = 0.000). Conclusion: Based on our study, holmium:YAG lithotripsy has a high success rate, and is a minimally invasive management, therefore it is a safe method for children bladder calculi treatment if proper equipment was available and done by expert hands.
