Khat is a natural stimulant from the Catha Edulis plant and is cultivated in the Republic of Yemen and certain areas of East Africa. Khat produces a modest degree of euphoria and slight hypomania. It results in insomnia and appears to improve the users' alertness and concentration. The main objective of this study was to determine ultrasound findings of urinary bladder among Yemeni khat chewers higher education students. Fifty khat chewers volunteers from higher Education levels were selected as cases, and twenty non-khat chewer volunteers at University level serving as control group. All of them were undergone urinary bladder ultrasound scan. This study revealed that the high frequency of students who chewed khat were from Dhamar area. The study showed that there is a linear relationship between the urinary bladder wall thickness and chewing Khat for years and hours and the residual urine volume is greater in students who chewed the Khat than the control group. Correlation is significant at the P=0.000 for chewing Khat for years and hours.
