Complications include esophagitis, esophageal stricture, and Barrett's esophagus. Progressive mechanical dysphagia is most likely due to peptic stricture or esophageal cancer. These include vesicoureteral reflux, urethral stricture, and stenosis. The procedure may be performed by a doctor to alleviate meatal stenosis or urethral stricture. Hence a retrograde urethrogram is essential for diagnosis of urethral injury, or urethral stricture. Esophageal stricture can usually be dilated using medical instruments. When in acute urinary retention, treatment of the urethral stricture or diversion is an emergency. The hallmark sign of urethral stricture is a weak urinary stream.
