Urachal remnants

Although urachal remnants rarely are observed clinically, they often give rise to a number of problems such as fatal infection and late malignant changes. Therefore, a total assessment of the disease with a particular focus on embryology, anatomy, and clinical symptoms, as well as the most advisable treatment, is called for. The authors report on 33 previously experienced cases and discuss the problems involved in both the diagnosis and treatment of these anomalies.
