Bladder outlet obstruction (or obstructive uropathy) occurs when urine is unable to flow from the kidneys through the ureters and out of the bladder through the urethra. Decreased flow of urine leads to swelling of the urinary tract, called hydronephrosis .

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.
Obstructive uropathy is a structural or functional hindrance of normal urine flow, [1] sometimes leading to renal dysfunction (obstructive nephropathy). It is a very broad term, and does not imply a location or cause.
Urethral slings may be used in both adults and children [12] [13] [14] Artificial Urinary Sphincters have shown good term outcomes in adults and pediatric patients. [ 15 ] [ 13 ] [ 16 ] An artificial urinary sphincter has three components: a control pump, an inflatable cuff that goes around the urethra, and a pressure regulating balloon. [ 17 ]
The protection provided by the foreskin for the glans penis and meatus has been recognized since 1915. In the absence of the foreskin the meatus is exposed to mechanical and chemical irritation from ammoniacal diaper (nappy) that produces blister formation and ulceration of the urethral opening, which eventually gives rise to meatal stenosis (a narrowing of the opening).

Urinary tract obstruction is a urologic disease consisting of a decrease in the free passage of urine through one or both ureters and/or the urethra. It is a cause of urinary retention . Complete obstruction of the urinary tract requires prompt treatment for renal preservation. [ 1 ]
Among children, urinary tract infections are most common in uncircumcised males less than three months of age, followed by females less than one year. [28] Estimates of frequency among children, however, vary widely. In a group of children with a fever, ranging in age between birth and two years, 2–20% were diagnosed with a UTI. [28]
