    Abstract:
    INTRODUCTION: The urachus is an embryologic remnant which is formed from the obliteration of the allantois. Urachal abnormalities are caused when defective obliteration of the urachus happens. They are an infrequent condition. Incidence is estimated to be between 5,000 and 8,000 live births. Its diagnosis and management remain a challenge due to the lack of an specific clinical picture and the controversy about the management. OBJECTIVE: The objective of this study is to assess the clinical presentation, diagnosis, therapeutic management, and outcomes of urachal anomalies in our health area. MATERIALS AND METHODS: We performed a retrospective review of all cases of urachal anomalies recorded Tenerife (southern health area), La Gomera, and El Hierro Islands during a 5 year period. RESULTS: Twenty-three cases of urachal pathology were included. The mean age of presentation was 32 years old. 73.9% were male. 65% were diagnosed in adults. In 30.3% of the cases, it was a casual finding. Symptoms included fever, umbilical exudate, hematuria, abdominal pain, and umbilical granuloma. The main diagnostic tests were ultrasound and computed tomography scan. Treatments were selected conservative management (43.5%), selective resection, partial cystectomy, and radical cystectomy. All patients had a good evolution. However, 2 cases where benign tumors were suspected, clinically, had a final histology of cancer in the specimen. CONCLUSIONS: Due to the lack of a specific clinical picture and undefined findings in image tools, diagnosis is difficult and it may be inaccurate. Despite more data are needed, our results suggest that the systematic excision of urachal lesions could result in safer outcomes since cases where a benign lesion is clinically suspected might result in malignant tumors.
