VALVULAS URETRALES POSTERIORES EPUB


Features that suggest posterior urethral valves are bilateral hydronephrosis, a thickened bladder wall with thickened smooth muscle trabeculations, and bladder diverticula.

Voiding cystourethrogram VCUG is more specific for the diagnosis. Normal plicae circularis are variable in appearance and often not seen on normal VCUGs.

PUV on voiding cystourethrogram is characterized by an abrupt tapering of urethral caliber near the verumontanumwith the specific level depending on the developmental variant. Very often the posterior urethra maybe dilated valvulas uretrales posteriores making the abrupt narrowing more obvious.

Diagnosis can also be made by cystoscopywhere a small camera is inserted into valvulas uretrales posteriores urethra for direct visualization of the posteriorly positioned valve.

A limitation of this technique is that posterior valve tissue is translucent and can be pushed against valvulas uretrales posteriores wall of the urethra by inflowing irrigation fluid, making it difficult to visualize.

Cystoscopy may also demonstrate the bladder changes. Centers in Europe and Japan have also had excellent results with cystosonography, although it has not been approved for use in the United States yet.
