    Abstract:
    OBJECTIVES: To determine the ideal management of uncomplicated adult urachal remnants and to confirm if conservative management with repeated imaging is acceptable. PATIENTS AND METHODS: This is a retrospective review of clinical notes and imaging of 45 patients with a mean age of 54.6 years who had been diagnosed with urachal anomalies at a single urology tertiary centre from January 2005 to December 2016. Patients who underwent surgical intervention and findings from patients managed non-operatively, with a mean follow up of 31 months, were evaluated. RESULTS: Thirty (66.7%) patients had incidental findings, while 15 (33.3%) were symptomatic. Eight underwent excision, one underwent an incision and drainage of abscess, while 34 of the 36 remaining patients elected to undergo surveillance with repeated ultrasound imaging. Two were lost to follow-up. Malignancy was confirmed in three patients. There was interval stability of the urachal remnant in all the patients in the non-operative cohort. The small sample size, limited follow-up, and retrospective nature of the study are recognised limitations. CONCLUSIONS: It was found that simple and asymptomatic lesions can be monitored with ultrasound, but effort must be made on initial diagnosis to ensure that malignancy is excluded using CT imaging and flexible cystoscopy where possible. Long-term follow-up of this cohort is required to assess the natural history of observed urachal anomalies.
