Renal function after release of ureteral obstruction: Role of endothelin and the renal artery endothelium

Kidney International, 1992
Glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) are decreased and mean arterial pressure (MAP) is increased after unilateral release of bilateral ureteral obstruction (BUO). An imbalance between vasoconstrictor and vasodilator substances may explain the hemodynamic alterations seen in this setting. The present study examines the

Microenvironment‐Responsive Nanomedicine Enables Vertical Modulation of Mitochondrial Pathological Networks in Myocardial Ischemia–Reperfusion Injury

Advanced Science, EarlyView.
A mitochondria‐targeted, microenvironment‐responsive nanoplatform enables pH/ROS‐triggered co‐delivery of berberine and isoliensinine to orchestrate ROS scavenging, inflammation suppression, and apoptosis inhibition. This vertical modulation of mitochondrial pathological networks preserves mitochondrial function and effectively mitigates myocardial ...

Predictive Value of Ureteral Jet Dynamics to Differentiate Postrenal Obstruction After Renal Transplantation: A Prospective Cohort Study

Journal of Urological Surgery, 2020
Objective:This study aimed to prospectively investigate the predictive value of ureteral jet dynamics measured by Doppler ultrasonography (D-US) to differentiate postrenal obstruction from other reasons after double-J stent (DJS) removal in patients who ...

Renal Function during Contralateral Arterial or Ureteral Obstruction

Kidney and Blood Pressure Research, 1978
Excretory function of one kidney of the rat was reduced acutely by either partial renal arterial occlusion, elevation of ureteral pressure or complete ligation of the renal pedicle. U_Na·V by the opposite kidney increased approximately twofold during partial arterial occlusion or elevated ureteral pressure and this was not ...

Pancreatic Atrophy: A Narrative Review and Surgical Interpretation

Annals of Gastroenterological Surgery, EarlyView.
Pancreatic parenchymal atrophy pattern and intraoperative margin assessment guide surgical strategy. ABSTRACT Despite recent advances in multimodal management, pancreatic ductal adenocarcinoma remains a fatal malignancy. Early detection of indirect findings of pancreatic ductal adenocarcinoma is essential to improve treatment outcomes, drawing ...

Prediction of Long‐Term Prognosis in Patients With Hepatocellular Carcinoma Using the National Clinical Database Risk Calculator

Annals of Gastroenterological Surgery, EarlyView.
This study aimed to determine the value of the National Clinical Database (NCD) risk calculator in predicting surgical outcomes and long‐term prognosis in patients undergoing resection for hepatocellular carcinoma (HCC). We retrospectively analyzed data from 210 patients with HCC who underwent initial hepatic resection, assessing the relationship ...

Ureteral obstruction by an aberrant renal artery: A case report

Indian Journal of Case Reports, 2018
The ureter is a muscular tubular structure that carries urine from the kidney to the urinary bladder. It is usually about 20–25 cmin length and 3–5 mm diameter. The upper half lies in the belly and the lower half in the pelvic area. A ureteral obstruction is ablockage of either unilateral or bilateral ureters that carry urine from the kidneys to the ...
