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.
Bladder outlet obstruction is included in the spectrum of congenital anomalies of the kidney and urinary tract (CAKUT). CAKUT is the most common cause of birth defects, occurring in 1 out of 1000 live births, and accounts for approximately half of all cases of chronic kidney disease and end-stage renal disease in children.

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.
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 ]
This can cause the inability to void urine even if the bladder is full and cause a large bladder capacity. The internal urinary sphincter can contract normally, however urinary incontinence is common. This type of neurogenic bladder is caused by damage to the peripheral nerves that travel from the spinal cord to the bladder. [5]
A disease known as benign prostatic hyperplasia may produce similar symptoms. [28] Other late symptoms may include feeling tired due to low levels of red blood cells. [28] 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 ...
Around one third of men will develop urinary tract (outflow) symptoms, of which the principal underlying cause is benign prostatic hyperplasia. [26] Once symptoms arise, their progress is variable and unpredictable with about one third of patients improving, one third remaining stable and one third deteriorating. [citation needed]
Benign prostatic hyperplasia (BPH), also called prostate enlargement, is a noncancerous increase in size of the prostate gland. [1] Symptoms may include frequent urination, trouble starting to urinate, weak stream, inability to urinate, or loss of bladder control. [1]
