Posterior urethral valve and anterior rectal duplication: a new combination

Abstract

We present a rare case of association of anterior rectal duplication and posterior urethral valve (PUV). A term neonate with no antenatal concerns was admitted with urosepsis and acute renal injury at 18 days of age. History revealed a poor urinary stream and dribbling. After resuscitation and stabilisation, renal tract ultrasound and micturating cysto-urethrogram were performed. Cystourethroscopy showed PUV and a mass indenting the bladder posteriorly. MRI confirmed the presence of a cystic lesion anterior to the rectum suspicious of rectal duplication. Laparoscopic-assisted excision of the anterior rectal duplication cyst was then performed. The infant recovered uneventfully. Creatinine normalised postoperatively and has been stable at follow-up.
