2024年6月9日 · The grading system of hydronephrosis developed by the Society of Fetal Urology (SFU) was devised to assess the degree of hydronephrosis. This system is considered the most commonly used and was originally designed to grade neonatal and infant pelvicalyectasis ref.

Backed by collaborative research, this module provides effective education for learning how to grade Hydronephrosis using the Society for Fetal Urology method.

The SFU Grade correlates with stasis and percent differential function (%df) as measured on "Well-Tempered Renogram" (WTR). See FAQ for details on stasis.

SFU-4 and UTD-P3 represent a considerable range of severity of hydronephrosis. Both represent minimal thinning of the medullary parenchyma and severe thinning of the cortical parenchyma (cyst-like hydronephrotic kidneys) at the same grade.

DEFINITION AND GRADING Overview — Several systems have been developed to diagnose and grade the severity of fetal hydronephrosis [1]. Renal pelvic diameter (RPD) Society of …

Neither AP diameter nor radiology, SFU, or UTD classification is the gold standard in determining the severity of hydronephrosis. All these grading systems are based on subjective parameters and are affected by many factors.

2021年7月23日 · In this study, we aim to compare the sensitivity and specificity of 2 classification systems that are used for hydro-nephrosis grading in ultrasound, for reflux and scar detection. The classification systems were the Society of Fetal Urology (SFU) and …

In partnership with government, associations and leading companies in British Columbia and across Canada, the SFU Clean Hydrogen Hub will dramatically lower the costs of clean hydrogen production, while co-developing technologies and products to decarbonize the Canadian economy and export around the world.

肾盂输尿管连接处梗阻 (ureteropelvic junction obstruction，UPJO)是尿液从肾盂流入近端输尿管的过程受阻 (如狭窄、瓣膜、息肉、高位输尿管开口、迷走血管压迫等)，进而导致集合系统扩张，压迫肾实质，并可能引起肾脏功能损害的一种先天性疾病。 它是胎儿肾积水最常见的病因，其发病率在1/1 500，男女发病比例约为2∶1 [1]。 UPJO的传统治疗方案为外科手术治疗，但有研究证明UPJO可以自发消退 [2]。 近几年对无症状UPJO更偏向于非手术治疗，但UPJO的最佳治疗方 …
