Adult posterior urethral valve: a case report.

Background: Posterior urethral valve (PUV) is a congenital obstructive defect of the male urethra with an incidence of 1/8,000 to 1/25,000 live births. PUV is the most common cause of lower urinary tract obstruction in neonates. The diagnosis of PUV is usually made early, and PUV cases have rarely been detected in adults.

Methods: Here we report the case of a 35 years old man presented with obstructive urinary symptoms. In spite of bladder neck rejection uroflowmetry pointed out infravesical obstruction with max. flow rate 9 ml/s and average flow rate 6 ml/s in uroflowmetry. During cystoscopy mild bladder trabeculation and resected bladder neck were seen. While the cystoscope was taken off, PUV were obtained.

Conclusions: Since PUV is a rare condition in adults and the diagnosis of PUVs is also difficult in these groups we must consider this situation during evaluation of adult patients with obstructive symptoms especially during cystourethroscopy.
