Massive pyuria as an unusual presentation of giant infected urachal remnant in a child

Abstract

Urachal remnants (URs) are manifestations of an incomplete regression of the urachus; therefore, there may be different types of remnants such as cyst, sinus tract, diverticulum or patent urachus. The clinical presentation of a urachal anomaly includes umbilical discharge, lower abdominal pain and urinary tract infection, although a UR may also be asymptomatic. We present the case of a 2.5-year-old girl who presented with abdominal pain, stranguria and massive pyuria in which a giant infected UR was found. The diagnosis was made using abdominal MRI. The child was subjected to laparoscopic-assisted drainage and had an uneventful postoperative course. Keywords : differential diagnosis, infected urachal remnant, laparoscopy, pyuria
