Maiden waist deformity

Maiden waist deformity is the appearance of the deviation of bilateral ureters. This typically occurs in retroperitoneal fibrosis. In this condition, there is medial indrawing of the ureters due to deposition of fibrous tissue in the lumbosacral junction. Due to involvement of both ureters, the course of the medially-drawn ureters is said to have the appearance of the narrow waist of a maiden, thus giving it its name.
