2023年8月28日 · DMSA scintigraphy shows defects in cortical uptake at the region of the scars with associated parenchymal volume loss. It is highly sensitive in detecting post VUR scarring in children less than 2 years of age who presents with febrile urinary tract infection.

What is a Renal DTPA Scan? A renal DTPA scan is a nuclear medicine exam in which a small amount of radioactive material (radioisotope) is used to measure the function of the kidneys, to see how the left and right kidney work comparatively. This test allows any sites of blockage to be identified and detected. How long does a Renal DTPA Scan take?

Our study shows that (1) the radioisotope (99m Tc-DTPA) determined GFR is a better determinant of renal function than EGFR; (2) neither GFR nor EGFR were significant indicators of risk for UTI, and for renal or urological structural lesions; (3) GFR predicted increased risk of mortality; and (4) the rate of decline of renal function was slow by ...

比较 99 Tc m -二巯基丁二酸 (DMSA)肾静态显像和 99 Tc m -二乙撑三胺五乙酸 (DTPA)肾动态显像测定的急性泌尿道感染 (UTI)患儿的相对肾功能 (RRF)。 回顾性分析2017年1月至2019年6月间无锡市人民医院临床确诊的病程<6个月的急性UTI患儿69例 [男29例，女40例；年龄 (45±38)个月；病程<6个月]。 所有患儿均行 99 Tc m -DMSA肾静态显像和 99 Tc m -DTPA肾动态显像。 利用感兴趣区 (ROI)技术勾画肾脏轮廓和肾周本底，分别计算双肾RRF。 2种显像方法测得的RRF差异比 …

Objective: This observational study: (a) compared serum creatinine (estimated glomerular filtration rate (EGFR)) to renal isotope 99m Tc-DTPA (GFR) determined glomerular filtration rate, and evaluated whether either method (b) better determined the state of renal function, and (c) predict urinary tract infection (UTI), renal and urological ...

2023年5月29日 · DTPA renal scan is commonly used to diagnose and evaluate various kidney conditions, such as renal artery stenosis, kidney function abnormalities, and urinary tract obstruction. It can help identify issues like reduced blood flow, blockages, and …

泌尿道感染(urinary tract infection, UTI)是儿科常见的感染性疾病之一[1] ,且婴幼儿UTI常合并膀胱输尿管反流(vesicoureteral reflux, VUR)等先天性尿路畸形(VUR 在婴幼儿发热性UTI中可高达20%~40%)。 VUR 和反复UTI可导致持续性的肾脏损害和瘢痕化,从而可能引起高血压和慢性肾脏疾病。 早期发现和诊断婴幼儿UTI,并给予合理处置尤为重要。 2010 年11月中华医学会儿科学分会肾脏学组在《中华儿科杂志》发表了UTI诊断治疗指南[2],对规范该病诊治起到了积极作用。

Urinary tract infection (UTI): Different guidelines are available for management of children with febrile UTI as shown in Table I [27-29]. Though not routinely practiced, DMSA can be performed during acute phase of UTI to confirm the presence of acute pyelonephritis in patients with equivocal symptoms.

Hydronephrosis, a consequence of renal stone disease, may lead to obstruction. Eventual loss of renal function may be related to the duration of hydronephrosis, associated urinary tract infection (UTI), previous surgery and/or calculi size. The present study was undertaken to evaluate renal function 1 and morphology by scintigraphic scan.

2025年2月11日 · Pre-treatment 99m Tc-DTPA dynamic renal scintigraphy GFR values and CRP levels are pivotal in assessing treatment efficacy for severe renal insufficiency secondary to UUTO, with the former being indispensable for evaluating compromised unilateral renal function.
