Direct portal vein recanalization with stenting associated with embolization of esophagogastric varices in a patient with portal vein thrombosis.

Introduction: Chronic extrahepatic non-tumoral thrombotic portal vein occlusion in non-cirrhotic patients is a rare condition, affecting 5-10% of patients with portal hypertension

Presentation Of Case: The present study reports the case of a young patient without previous comorbidities who presented with portal hypertension secondary to chronic extrahepatic non-tumoral thrombotic occlusion of the portal vein.

Boari-Flap reconstrution due to a total ureteral avulsion in a patient with ipslateral ureterolithiasis and contralateral renal nodule.

The ureteral avulsion during ureterolithotripsy (URS) occurs due to the sudden movement of the optical device or endoscopic extractor either in its removal or insertion, associated with a probable previous lesion in the ureter wall, causing a vital fragility area. A 52-year-old male patient with, an obstructive calculus of 9 mm was found in the left middle ureter, and a heterogeneous hypervascular nodule located in the right kidney, suggesting neoplasia.
