UTIs are treated with medicines called antibiotics, which kill the germs. Some boys with PUV get UTIs that keep coming back, even after treatment – these are called recurrent UTIs.
Do females have posterior urethral valves?
Abstract. Congenital posterior urethral valves are a common cause of severe lower urinary tract obstruction in young males (4, 6). Some authors have stated that urethral valves occur exclusively in males (2, 6), but others have indicated that the lesions may rarely be encountered in females (3–5, 7).
How is posterior urethral valve diagnosed?
The diagnosis of posterior urethral valves is made by radiographic imaging with ultrasound and voiding cystourethrogram. Ultrasound will usually show a dilated urethra, bladder, and kidneys; it is supportive of the diagnosis of posterior urethral valves, but not confirmatory.
What does PUV mean in pregnancy?
