Abstract
We report 2 cases of patients with umbilical urachal sinus who underwent laparoscopic complete resection of the urachus with partial cystectomy. A 32-year-old woman and a 27-year-old man with purulent discharge from the umbilicus were referred to our hospital. They were diagnosed with umbilical urachal sinus by abdominal CT. After remission of the umbilical infection, both patients underwent laparoscopic complete resection of the urachus with partial cystectomy. In both patients, the histopathological findings revealed urachal remnant in the bladder cuff area. There is no consensus about whether a bladder cuff should be resected routinely. Based on our experience, we believe that complete resection of the urachus with partial cystectomy is desirable, even for umbilical urachal sinus.
