ICD-11 MMS 2026-01

Fetal lower urinary tract obstruction

Description

A disease caused by partial or complete obstruction of the urethra, during the antenatal period. This disease can present with enlarged bladder, oligohydramnios, or pulmonary hypoplasia. Confirmation is through observation of the obstruction by imaging.
