Urachal-Tumor Cutting Laparoscopic Surgery
2 years ago
The urachus is a tube-like structure that forms in a developing embryo. It connects the umbilical cord to the urinary bladder before birth. After birth, the urachus usually shrinks into a small ligament. However, traces of the urachus (called urachal residues) can be detected in up to one-third of adults. Urachal residues usually do not cause any symptoms.
A growth of cancerous cells that starts in the urachus is called urachal cancer. Urachal carcinoma is rare and comprises 0.35 to 0.7 % of all bladder cancers and 22-35% of vesical adenocarcinomas.
