Robot-assisted laparoscopic management of urachal cysts in adults.

We report two cases where a urachal cyst was managed by robot-assisted laparoscopic surgery. A 47-year-old man and a 43-year-old woman presented with gross hematuria and lower abdominal pain, respectively. Diagnosis of urachal cyst was established by computed tomography imaging. Robot-assisted laparoscopic surgery was performed transperitoneally via four ports. Both patients were diagnosed as having a urachal cyst with inflammation. Our experience suggests that robot-assisted laparoscopic excisions of urachal cysts can be performed easily and safely in adults.
