Abstract

Objective

Vesicoureteral reflux (VUR) index is a simple, validated tool that reliably predicts significant improvement and spontaneous resolution of primary reflux in children. The aim of this study was to evaluate and compare the ureter diameter ratio (UDR) and VUR index (VURx) of patients treated with endoscopic injection (EI) and ureteroneocystostomy (UNC) methods in the pediatric age group due to primary VUR.

Methods

Patients under the age of 18 years old who underwent EI and UNC with the diagnosis of primary VUR between January 2011 and September 2021 were determined as the participants. The UDR was assessed using voiding cystourethrography, and the VURx score was determined prior to treatment based on hospital records included in the study.

Results

A total of 255 patients, 60 (23.5%) boys and 195 (76.5%) girls, with a mean age of 76.5 (range 13.0–204.0) months, were included in the study. EI was applied to 130 (51.0%) patients and UNC was applied to 125 (49.0%) patients due to primary VUR. The optimum cut-off for the distal UDR was obtained as 0.17 with sensitivity and specificity of 73.0% and 63.0%, respectively. The positive and negative predictive values were 66.0% and 70.0%, respectively.

Conclusion

When the UDR and VURx score are evaluated together for the surgical treatment of primary VUR in the pediatric age group, it is thought that it may be useful in predicting the clinical course of the disease and evaluating surgical treatment options.

输尿管直径比和膀胱输尿管反流指数在治疗原发性膀胱输尿管反流中的应用评估

目的膀胱输尿管反流（VUR）指数是一种简单、有效的工具，能可靠地预测儿童原发性反流的显著改善和自发缓解。本研究旨在评估和比较因原发性输尿管返流而接受内窥镜注射（EI）和输尿管膀胱造口术（UNC）治疗的儿科年龄组患者的输尿管直径比（UDR）和输尿管返流指数（VURx）。研究共纳入 255 例患者，其中男孩 60 例（23.5%），女孩 195 例（76.5%），平均年龄 76.5 个月（13.0-204.0 个月）。130 名（51.0%）患者采用了 EI，125 名（49.0%）原发性 VUR 患者采用了 UNC。远端 UDR 的最佳临界值为 0.17，灵敏度和特异度分别为 73.0% 和 63.0%。结论当 UDR 和 VURx 评分一起用于评估儿科原发性 VUR 的手术治疗时，它可能有助于预测疾病的临床过程和评估手术治疗方案。

期刊介绍： Asian Journal of Urology (AJUR), launched in October 2014, is an international peer-reviewed Open Access journal jointly founded by Shanghai Association for Science and Technology (SAST) and Second Military Medical University (SMMU). AJUR aims to build a communication platform for international researchers to effectively share scholarly achievements. It focuses on all specialties of urology both scientifically and clinically, with article types widely covering editorials, opinions, perspectives, reviews and mini-reviews, original articles, cases reports, rapid communications, and letters, etc. Fields of particular interest to the journal including, but not limited to: • Surgical oncology • Endourology • Calculi • Female urology • Erectile dysfunction • Infertility • Pediatric urology • Renal transplantation • Reconstructive surgery • Radiology • Pathology • Neurourology.
