Spontaneous vesicoureteral reflux resolution curves based on ureteral diameter ratio

Journal of Pediatric Urology, 2023
Various factors influence the clinical course of vesicoureteral reflux (VUR) in the pediatric population. Distal ureteral diameter ratio (UDR) is an objective measure reflective of ureterovesical junction anatomy that has been shown to independently predict both spontaneous resolution and breakthrough febrile urinary tract infection (UTI) in children ...

Nitrogen removal and nitrous oxide emission in the partial nitritation/anammox process at different reflux ratios.

Science of the Total Environment, 2023
The partial nitritation/anammox (PN/A) process has been widely used in wastewater treatment owing to its notable advantages, including a low aeration rate and the non-requirement of an additional carbon source.

Efficient azo dye wastewater treatment in a hybrid anaerobic reactor with a built-in integrated bioelectrochemical system and an aerobic biofilm reactor: Evaluation of the combined forms and reflux ratio.

Bioresource Technology, 2019
A combined process that consisted of a hybrid anaerobic reactor (HAR) with an integral bioelectrochemical system and aerobic biofilm reactor (ABFR) was established for simulated azo dye wastewater treatment (domestic wastewater containing dye acid orange

Ratio Between Proximal/Distal Gastroesophageal Reflux Does Not Discriminate Abnormal Proximal Reflux

World Journal of Surgery, 2013
AbstractIntroductionThe threshold for pathologic proximal acid reflux is a controversial topic. Most values previously published are based on absolute numbers. We hypothesized that a relative value representing the quantitative relation between the amount of acid reflux that reaches proximal levels and the amount of distal reflux would be a more ...

Effect of the method of falling water aeration-reflux on nitrogen removal and applicability in a novel upflow microaerobic sludge reactor treating low carbon-to-nitrogen ratio wastewater.

Bioresource Technology, 2019
A novel falling water aeration-external reflux upflow microaerobic sludge reactor (UMSR) was designed to treat wastewater with the low chemical oxygen demand (COD) to total nitrogen (TN) ratio. The result showed the concentration of dissolved oxygen (DO)

Predicting Breakthrough Urinary Tract Infection: Comparative Analysis of Vesicoureteral Reflux Index, Reflux Grade and Ureteral Diameter Ratio

Journal of Urology, 2020
The vesicoureteral reflux index is a simple, validated tool for predicting resolution of reflux. Along with likelihood of spontaneous resolution identification of children at risk for febrile urinary tract infection impacts management. We evaluated the usefulness of the vesicoureteral reflux index as a predictive factor for breakthrough febrile urinary

Risk factors and long-term course of gastroesophageal reflux disease after peroral endoscopic myotomy: A large-scale multicenter cohort study in Japan.

Endoscopy, 2022
BACKGROUND : Gastroesophageal reflux disease (GERD) and reflux esophagitis remain problems after peroral endoscopic myotomy (POEM). This study aimed to elucidate the risk factors and long-term course of reflux esophagitis and symptomatic GERD after POEM.

The Impact of Reflux Ratio on Rectification Column Theoretical Plate Number

Advanced Materials Research, 2011
In this paper, the computer-aided calculation is introduced to study the influences of the reflux ratio on the theoretical plate number of rectification column. It is found that the number of theoretical plates of rectification column is increasing as the decreasing of the reflux ratio, which is mainly caused by the increasing of the plate number in ...
