Abstract

Posterior urethral valve (PUV) disorder is an obstructive developmental anomaly in the urethra and genitourinary system of male newborns [1]. A posterior urethral valve is an obstructing membrane in the posterior male urethra as a result of abnormal in utero development. It is the most common cause of bladder outlet obstruction in male newborns. PUV may cause the kidneys to swell-this is called antenatal hydronephrosis and is a common problem for babies in the womb. Occasionally, this causes more serious problems. Boys with PUV may be more likely to get urinary tract infections (UTIs) when germs get into the urine and cause infection and illness. These are treated with medicines. In some cases, boys with PUV get a serious infection in their kidneys or in their blood. PUV may cause vesicoureteral reflux (VUR)- when urine refluxes (goes back up) the wrong way towards or into the kidneys.20-30 of patient had renal failure even if treated.
