Abstract

Introduction: Ureteral stone impaction can significantly affect the success of ureteroscopy (URS) in children. While the factors predicting impaction have been well studied in adults, data in children are limited. This study aimed to identify factors that predict ureteral stone impaction in children undergoing URS and to compare the success rates and complications based on the stone impaction status. Patients and Methods: Pediatric patients undergoing URS for ureteral stones were retrospectively reviewed. Impaction status of the stones was evaluated by radiological parameters and the children were divided into two groups based on the presence of stone impaction. Peri- and postoperative findings were comparatively evaluated in patients with or without stone impaction. Results: A total of 102 pediatric patients were included (40 with impacted stones, 62 with nonimpacted ureteral stones). The mean age was 9.3 ± 5.3 years. Univariate analysis showed significant differences between the groups in degree of hydronephrosis, presenting symptoms, stone density (HU), stone size, upper ureteral diameter, and that of ureteral wall thickness (UWT) (p = 0.004, p = 0.044, p = 0.033, p = 0.005, p = 0.012, p = 0.000, respectively). Multivariate analysis revealed UWT as the only independent predictor of stone impaction, with a cutoff value of 2.63 mm showing 83% sensitivity and 82% specificity (p = 0.000). The highest UWT value in the nonimpacted stone group was 3.1 mm. The mean operation time was found to be significantly longer in cases with impacted stones (p = 0.000). Kids with impacted stones had lower mean success rate (impacted = 70%, nonimpacted = 88.7%) and higher mean rate of complications, longer duration of DJ-stenting, more anesthesia sessions (p = 0.018, p = 0.019, p = 0.000 and p = 0.000, respectively). Conclusions: Similar to the adult cases, UWT could be used as a reliable parameter in predicting the impaction status of ureteral stones in pediatric patients. Impacted ureteral stones may reveal decreased success and higher complications rates during and after endoscopic stone surgery in these cases.

输尿管结石嵌塞及其对儿童内镜治疗结果的可能影响:一项重点关注输尿管壁厚度的关键评估。
导读:输尿管结石嵌塞对儿童输尿管镜手术的成功率有显著影响。虽然预测影响的因素已经在成人中得到了很好的研究,但儿童的数据有限。本研究旨在确定预测尿路泌尿系手术儿童输尿管结石嵌塞的因素,并根据结石嵌塞情况比较成功率和并发症。患者和方法:回顾性分析输尿管结石行尿路治疗的儿童患者。通过放射学参数评估结石嵌塞状况,并根据是否存在结石嵌塞将儿童分为两组。对有无结石嵌塞患者的围手术期和术后结果进行比较评价。结果:共纳入102例儿童患者(40例为阻生结石,62例为非阻生输尿管结石)。平均年龄9.3±5.3岁。单因素分析显示,两组患者在肾积水程度、表现症状、结石密度(HU)、结石大小、输尿管上径、输尿管壁厚度(UWT)方面差异均有统计学意义(p = 0.004, p = 0.044, p = 0.033, p = 0.005, p = 0.012, p = 0.000)。多变量分析显示UWT是结石嵌塞的唯一独立预测因子,截止值为2.63 mm,敏感性为83%,特异性为82% (p = 0.000)。无冲击结石组最大UWT值为3.1 mm。阻生结石患者的平均手术时间明显延长(p = 0.000)。阻生结石患儿平均成功率较低(阻生= 70%,非阻生= 88.7%),平均并发症发生率较高,dj支架置入术时间较长,麻醉时间较多(p = 0.018, p = 0.019, p = 0.000和p = 0.000)。结论:与成人病例相似,UWT可作为预测小儿输尿管结石嵌塞情况的可靠参数。在这些病例中,阻生输尿管结石在内窥镜结石手术期间和之后的成功率降低,并发症发生率更高。

期刊介绍: Journal of Endourology, JE Case Reports, and Videourology are the leading peer-reviewed journal, case reports publication, and innovative videojournal companion covering all aspects of minimally invasive urology research, applications, and clinical outcomes. The leading journal of minimally invasive urology for over 30 years, Journal of Endourology is the essential publication for practicing surgeons who want to keep up with the latest surgical technologies in endoscopic, laparoscopic, robotic, and image-guided procedures as they apply to benign and malignant diseases of the genitourinary tract. This flagship journal includes the companion videojournal Videourology™ with every subscription. While Journal of Endourology remains focused on publishing rigorously peer reviewed articles, Videourology accepts original videos containing material that has not been reported elsewhere, except in the form of an abstract or a conference presentation. Journal of Endourology coverage includes: The latest laparoscopic, robotic, endoscopic, and image-guided techniques for treating both benign and malignant conditions Pioneering research articles Controversial cases in endourology Techniques in endourology with accompanying videos Reviews and epochs in endourology Endourology survey section of endourology relevant manuscripts published in other journals.
