“…Another study by Linjin et al 17 also confirmed less operating time with LL (28 ± 9.2 vs 41 ± 12.4, p 0.001) as suggested by our study. Zyczkowski M et al 18 studied 108 children and found statistically significant shorter MOT in LL group (34 vs 56 minutes, p 0.04).…”

Objective: To compare the mean operative time (MOT) in patients undergoing Ho: YAG laser lithotripsy (LL) and pneumatic lithotripsy (PL) for ureteric stones. Methods: This randomized study was conducted at Armed Forces Institute of Urology (AFIU) Rawalpindi, Pakistan from July 2016 to November 2018. Non probability consecutive sampling technique utilized to enroll 60 patients of both gender aged 18-60 years, having ureteric calculus ≤1.5cm. Randomization was done into group I (LL) and II (PL) via computer generated number tables. Six Consultant Urologists performed surgeries under spinal anesthesia utilizing Swiss Lithoclast® Master (EMS+ S.A. Switzerland) in group II and holmium laser fiber (365μm, 8-10Hz, 9.6-16W, 2100nm wavelength) in group I respectively. MOT was noted from insertion of cystoscope till removal out of meatus. Data obtained was analyzed through IBM SPSS 24.0. Results: Analysis involved 60 patients (30 each group) having similar baseline characteristics (age, gender, laterality, location). There was statistically significant different MOT between LL & PL (25.48±6.99 vs 34.83±7.47 minutes, p < 0.001). Data stratification with respect to age, gender, laterality and stone location revealed similar trend. Lithotripsy technique significantly affected MOT (p < 0.001) on Multiple Linear Regression Analysis. Conclusions: Ho: YAG LL is an efficient technique when compared with PL in terms of MOT for ureteric stones. doi: https://doi.org/10.12669/pjms.37.2.3049 How to cite this:Sajid MT, Ameen M, Murtaza B, Alvi MS, Khan Z, Kiani F.

“…19 In another study about the application of both of these technologies in renal and ureteral stones in pediatric age groups, Marcin et al concluded that Ho: YAG laser reduced the operation time and increased the efficacy of treatment, especially in renal calculi in comparison to LL. 20 Yin et al in their meta-analysis found that Ho: YAG LL had significant superiority in comparison to PL in terms of early stone-free rate, delayed stone-free rate, shorter operative time and lower stone migration rate, but not yet in the postoperative hematuria rate and the ureteral perforation rate. 4 They did not have any comparison between the costs of these procedures.…”

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.

“…The duration of lithotripter activation differs in almost every referenced research; the reason could be the composition and size of the targeting stone 24 . Another study indicated lower operative duration and higher clearance rates in the holmium YAG laser group as compared to pneumatic 25 . Although the safety profile of Ho YAG: Laser is improved as compared to pneumatic lithotripter, the choice of using this modality is still doubtful for proximal ureteric stones.…”

Background: Holmium YAG (yttrium-aluminum-garnet) laser, a comparatively new technique, can clear all types and sizes of stones and is only being used in two institutes of Karachi, Pakistan. The study aimed to compare pneumatic lithoclast and holmium YAG laser, to evaluate stone-free rate (SFR), postoperative complications, operative duration, and effectiveness. Methods: This cross-sectional research included 60 patients with age 16-65 years having ureteric stones, reporting to kidney center, Urology Department, Karachi, Pakistan. CT Scan of Kidneys, Ureter, and Bladder (KUB) were used to record stone size, laterality, and location within the ureter. Patients were divided into two clusters of 30 each, group A (Ho: YAG laser) and group B (pneumatic Lithoclast) having 0.5 to 02 cm of size ureteric stones. An Independent two-sample “t” test was used to assess the difference for the continuous variables. A p-value of ≤0.05 was considered statistically significant. Results: Stone sizes distribution was 1.3±0.3cms and 1.4±0.3cms for A and B groups respectively (p=0.8). The insignificance of the p-value demonstrated no substantial divergence between both groups and stone sizes. Clearance from the proximal ureter was noted 26(84.6%) in group A and 41.7% in group B with (p<0.05). A reduced lithotripsy activation period of 30.8±3.7mins was associated with stone size (p<0.05). Conclusion: Holmium: YAG Laser had better stone-free rate (SFR), with 84% clearance than pneumatic. Improved and effective clearance reduces the risk of residual stones within a lesser time, required for getting back to normal life routines.
