Simple renal cysts are one of the most common lesions in elderly. These cysts are usually asymptomatic but when the size of these
cysts increase, we would see symptoms such as hypertension, hematuria, flank pain or urinary obstruction. In this study, we explore a
case of small bowel obstruction that presented with nausea, repeated vomiting that causes hematemesis, and a submucosal obstructive
lesion that was seen in Esophagogastroduodenoscopy (EGD). After endoscopic ultrasound (EUS) evaluation, we detected a large
simple renal cyst and approved our diagnosis with CT scan. We planned a medical treatment for this patient that consist consuming
small size meals, 5 to 6 times a day, and high calorie liquids in small volumes. We conclude that simple renal cyst can be one of the
cause of extrinsic intestinal obstruction and EUS is affective for differentiation of intrinsic submucosal lesion from extrinsic
