✦ Synopsis

Objectzue: To evaluate the frequency of the visualization of urachal remnants (UR) with ultrasound and to determine their sonographic patterns.

Subjects and methods: Two hundred and fifty consecutive patients were referred for abdominal andlor pelvic ultrasonography, 83 who had urinary tract symptoms. Patient age ranged from 1 month to 91 years (mean = 35 years). Patients were classified into four groups: (1) <16 years ( n = 47) (2) 16-35 years ( n = 1001, (3) 36-55 years ( n = 49), (4) a56 years ( n = 54). Ultrasonography was performed using 3.75 MHz and 7.5 MHz transducers. Ultrasound criterion for diagnosis was a midline mass located between the rectus abdominus muscle and the upper part of the anterior bladder wall.

ResuZts: UR were found in 90 cases (36%). UR demonstration was more frequent in groups 1 (61.7%) and 2 (49%) and 3 (20.4%) and 4 (3.7%). UR were nodular (87%) or tubular in structure (13%). Echogenicity was similar to or greater than adjacent muscle in 51% and less than in 49%. The length, width, and thickness mean and standard
