[Diagnosis and treatment of urachal remnants with heterotopia sinus: a report of 2 cases].
OBJECTIVE
To probe into the diagnosis and treatment of urachal remnants with heterotopic sinus.


METHODS
Two cases with penis dorsal drainage for 5 approximately 6 years were diagnosed as urachal anomaly by sinus probing, methylene blue injection test, cystoscope examination, and type B ultrasonic examination, and both received surgical removal of the urachus and all the abnormal tissues associated with it.


RESULTS
Surgery and pathology proved urachal cyst with communication drainage in both of the patients. Follow-up survey showed no recurrence and malignancy.


CONCLUSIONS
Sinus probing, mythylene blue injection test and type B ultrasonic examination are effective methods for the diagnosis of urachal remnants with heterotopic sinus. Surgical treatment should include radical removal of the urachus and the abnormal tissues associated with it.
