Intramural Ureter and Ureterocele

DURING the past ten years much research has been directed to the study of the structure and function of the normal intramural part of the ureter. The anatomy of the uretero-vesical 'lock' mechanism of both the normal and abnormal variants of this part of the ureter is now more clearly understood. It is proposed to describe the short, the long, and the structurally abnormal intra-mural ureters, together with the physiological defects which they involve and which provoke clinical problems.
