Background: Holmium:yttrium-aluminium-garnet (Ho:YAG) laser lithotripsy with ureteroscopy (URS) was a safe and successful treatment option for pediatric ureteral stones. We aimed to comparatively evaluate the outcomes of 15 and 30 W Ho:YAG laser lithotriptors in pediatric ureter stones.Materials and Methods: We retrospectively evaluated 55 children who underwent ureteroscopic laser lithotripsy to treat ureter stone size up to 15 mm between September 2009 and March 2020. Groups were formed according to the laser lithotriptor power 15 W (Group 15: n = 32), 30 W (Group 30: n = 23). The efficiency of laser lithotriptors was compared between the groups.Results: The age, gender, and stone characteristics (longest stone diameter, density, location and multiple stones) were similar between the groups. In the postop first month, stone-free status was achieved in all cases except one child in Group 15. The median operative time was significantly shorter in Group 30 (40 minutes) than in Group 15 (52.5 minutes) (P = .010). Clavien-Dindo class (CDC) 2 complications occurred in 2 children in both groups (P = .597). Although ureteric stenosis was observed in 1 patient in Group 15, no ureteric stenosis was seen in Group 30 during follow-up (median 16.1 months). Length of hospital stay (LoHS) and stone-free rates were similar between groups.Conclusion: URS with 15 and 30 W Ho:YAG laser lithotriptors is an effective treatment option for pediatric ureteral stones with a high success rate and low complication rates. In brief, 30 W Ho:YAG laser lithotriptors should be preferred over 15 W lithotriptors due to their shorter operative time with similar success rate.

Background:We aimed to compare the results of patients who underwent laparoscopic adrenalectomy (LA) for masses >= 6 cm versus Materials and Methods:Three hundred thirty consecutive patients were divided into two groups according to tumor size (>= 6 and <6 cm in diameter). Demographic variables, body mass index (BMI), lesion localization (right/left), tumor diameter, pathological diagnosis and surgical outcomes, including operation time, estimated blood loss (EBL), conversion to open surgery, complications, and length of hospital stay were compared between groups. Results:Between February 2008 and March 2020, 53 patients (29 male-24 female) with >= 6 cm (L group) adrenal tumor and 277 patients (105 male-172 female) with <6 cm tumor (S group) underwent transperitoneal LA. One hundred sixty-eight (50.9%) tumors localized on the left side. In L group mean tumor size in female and male patients was 87.5 +/- 40.8 mm (range 50-225 mm) and 67.3 +/- 18.4 mm (range 10-100 mm), respectively (P < .05). Age, American Society of Anesthesiology scores, BMI, and mean operation time were similar between groups (P > .05). Postoperative complications were more often in L group (P = .005). EBL in group L and group S was 86 +/- 70.4 mL (range 10-500 mL) and 55 +/- 44.2 mL (range 10-300 mL), respectively (P = .003). Length of hospital stay in group L and group S was 3.7 +/- 3.5 days (range 1-26) and 3 +/- 1.6 days (range 1-9), respectively (P = .086). Significant variables in multivariate analysis, including gender (male), EBL, and postoperative complication rate, were entered into multivariate regression analysis, which presented that EBL and postoperative complication rates were independent significants for the L group. Conclusion:Six centimeters should not be considered as an upper limit of transperitoneal lateral LA and may be safely performed in centers with experience. Further studies are needed to confirm our data.

OBJECTIVES: We aimed to understand whether laparoscopic ureterolithotomy (LU) is a good alternative to flexible ureterorenoscopic lithotripsy (FURS) by comparing these techniques concerning cost-effectiveness.METHODS: We analysed 79 patients with upper ureteral stones larger than 1.5 cm underwent FURS or LU concerning cost-effectiveness analysis. The data including age, body mass index (BMI), stone size, operation time, hospitalisation time, complications and stone-free rates of 15th day and 3rd months. We audited the costs of FURS and LU and compared them concerning cost-effectiveness.RESULTS: There was not any statistically significant difference between the two groups with regard to age, BMI, stone size, stone-free rates at the 3rd month, and complication rates, (p>0.05).The operation times were statistically lower in the FURS than in the LU (61.5 +/- 24.3 min and 140.9 +/- 49.1 min, respectively, p<0.05). The stone-free rate at the 15th day was lower in the FURS group than in the LU group (31 (81.6%) and 41 (100%), respectively, p<0.05) (Table I).However, this statistical difference disappears at 3 months (p>0.05). The mean costs of FURS and LU were $194.2 +/- 12.4 and $179.2 +/- 58.5, respectively (p<0.001).CONCLUSION: FURS is equally effective to LU in terms of stone-free rates. The cost of FURS is higher statistically than LU. FURS is shown as the first choice for the upper ureteral stones larger than 10 mm in size, if the laparoscopic experience is in high-level situations in that clinic, LU may be a suitable alternative to FURS, especially for challenging cases.

Introduction: We aimed to compare the effectiveness of 15- and 30-W holmium: yttrium-aluminum-garnet (Ho:YAG) laser devices used in the treatment of pediatric kidney stones.Methods: Eighty-six consecutive pediatric patients who underwent retrograde intrarenal surgery (RIRS) between February 2010 and August 2020 were enrolled in the study. After exclusion criteria were applied, the data of 79 children were evaluated retrospectively. Patients were divided into two groups according to the laser device power of 15 W (Group 15: N = 30) and 30 W (Group 30: N = 49). The groups were compared according to demographic characteristics, stone feature, and clinical efficacy.Results: The age, gender, height, weight, and stone characteristics were similar between the groups. The mean operation time was shorter in Group 30. The stone-free rate after the first RIRS session (SF1) was 66.7% in Group 15 and 83.3% in Group 30. The SF1 for 20-mm or larger kidney stones was found to be 0% in Group 15 and 62.5% in Group 30. However, there was no statistically significant difference between the two groups in terms of stone-free rate.Conclusions: In pediatric kidney stone treatment, 30-W Ho:YAG laser devices should be preferred as they shorten the operation time compared with 15-W devices and provide the final stone-free status with fewer procedures, especially in large kidney stones.
