Abdominal computed tomography(CT) and magnetic resonance imaging(MRI) revealed an abscess in the umbilical region that was connected to the bladder via a long band, in part via a long tube-like structure(Fig. 1).
surgical incisions and abdominal wall-lift/A 15 mm infra-umbilical incision and a 6 cm Pfannenstiel incision, two wires were placed for wall-lift.

For the abdominal wall-lift, two wires were placed subcutaneously and pulled upward, 2 cm below the umbilicus and halfway between the umbilicus and the pubis, respectively (Fig. 2).
laparoscopic view from the umbilical incision/The dissection was mostly performed in the preperitoneal space and sometimes in the abdominal cavity (A, B). Pfannenstiel incision was added to get access to the conjunction of the urachal remnant to the bladder (C). The peritoneal defects were closed with several running sutures (D).

The peritoneal defects were closed with several running sutures under a laparoscopic view from the umbilical incision (Fig. 3).
Pathological findings/The sinus had a lumen lined mostly with transitional and columnar epithelia. The lumen near the umbilicus was covered with stratified squamous cells. Inflammatory cell infiltration was mild and no abscess formation was found. These findings were pathomorphologically compatible with the urachal sinus.
