Urachal remnants (UR) are clinically significant conditions with both infectious and malignant potential. However, the long-term outcomes of surgical treatment remain poorly documented. We retrospectively analyzed the clinicopathological features and long-term outcomes of 14 adult patients with UR complicated by purulent omphalitis. The cohort comprised 12 men and 2 women, with a median age of 32.5 years (range, 21-69 years). Non-elective surgery was performed in seven patients. A histopathological examination confirmed microscopic urachal structures in 10 cases, whereas marked inflammatory infiltration precluded definitive identification of urachal tissue in four cases. All patients underwent meticulous postoperative monitoring. During a median follow-up of 78 months (range, 46-183 months), no recurrence of omphalitis was observed. These findings suggest that surgical resection may achieve durable disease control even without the histological confirmation of urachal tissue.
