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] Any sign of infection, such as fever and chills, in the context of obstruction to urine flow constitutes a urologic emergency.[1]

Causes

Causes of urinary tract obstruction include:

Congenital urinary tract obstruction

Urinary tract obstruction as a

congenital disorder results in oligohydramnios which in turn can lead to the Potter sequence of atypical physical appearance. Pulmonary hypoplasia is by far the main cause of death in the early neonatal period for children with congenital lower urinary tract obstruction.[3]

randomized yet small study.[3]


Urinary tract obstruction due to foreign object

While uncommon, there are case reports in the human and veterinary literature of a bullet or other ballistic projectile migrating to the urethra and causing a urinary tract obstruction. This has been reported in people, small animals, and a goat.[4]

Sitting voiding position

A

LUTS showed that in the sitting position, the residual urine in the bladder was significantly reduced. The other parameters, namely the maximum urinary flow and the voiding time were increased and decreased respectively. For healthy males, no influence was found on these parameters, meaning that they can urinate in either position.[5]

Diagnosis

Treatment

Treatment depends on the underlying cause of the obstruction and the severity of the symptoms.[citation needed]
