Posterior Urethral Valves (PUV) is a common fetal anomaly affecting in an obstructing membrane in the posterior male urethra restricting normal bladder emptying. PUJ causes a severe type of urinary obstruction and damages the urethra, bladder, ureters and kidneys.
Causes and Symptoms:
It occurs in the uterine development which happens by chance. The symptoms can be mild to severe UTI’s, enlarged bladder which can be detected through the abdomen, painful urination, poor weight gain and a weak stream of urine.
PUJ can be diagnosed during fetal development, later diagnosed if the child often develops UTI, a blood test for kidney function, abdominal ultrasound and specific x-ray called VCUG are performed to confirm the diagnosis.
Urinary Tract Infection, dehydration, and electrolyte imbalance is managed by antibiotics and intravenous fluids.
In this the urologist inserts an endoscope through the urethra and will examine the obstruction and removes the leaflets through a small incision on the ureteral valve.
The urologist will make a small opening in the in the bladder through the abdomen to continuously drain the urine out of the bladder.
