Prune-belly Syndrome versus Posterior Urethral Valve

Abstract

Recent development of three-dimensional (3D) and four-dimensional ultrasound (4D), specially using tomographic ultrasound image (TUI), inverse mode, automatic volume calculation (AVC) and virtual organ computer-aided analysis (VOCAL), provided us with new possibilities to study fetal low urinary obstructions before 24th week. Ultrasound scan studies have been conducted in order to provide information about prune-belly syndrome and posterior urethral valves (PUV). The purpose of this paper is to give brief anatomical, histological and ultrasound review to use 3D and 4D US in the assessment of both syndromes.
