Abstract
Urachal cancer is a rare non-urothelial malignancy that involves the urachus, often occurring at the junction of the urachal ligament and the bladder dome. It accounts for less than 1% of all bladder tumours. Cancer during pregnancy is rare, with the incidence of all cancers in pregnancy estimated to be 25-27 per 100 000 pregnancies. Urachal cancer in pregnancy is an even rarer phenomenon, with only a handful of case reports published to date. After a systematic review, only five cases have been reported in the English literature. We aim to review the cases presented in the literature and to examine the outcomes of the management of urachal cancer in pregnancy to date.
