Patients admitted to the Pediatric Urology Clinic of Sancaktepe Şehit Prof. Dr. İlhan Varank Training and Research Hospital who underwent evaluation for constipation using ultrasonographic rectal diameter measurement in conjunction with Rome IV criteria.
Exclusion Criteria:
Children diagnosed with constipation according to Rome IV criteria who underwent transabdominal ultrasonographic measurement of rectal diameter.
Diagnostic Test: Ultrasonographic rectal diameter measurement
Children without symptoms of constipation who underwent transabdominal ultrasonographic measurement of rectal diameter.
Diagnostic Test: Ultrasonographic rectal diameter measurement
Transabdominal ultrasonographic measurement of rectal diameter was performed to evaluate fecal retention and diagnose constipation in children. Rectal diameter measurements were compared with clinical diagnostic criteria.
