The Pseudo-Bladder: A Case of the Prostatic Urethra Masquerading as the Bladder.

Congenital bladder underdevelopment has detrimental genitourinary effects. We present a male infant with declining renal function, recurrent urinary tract infections, and epididymo-orchitis, in the setting of bilateral high grade hydronephrosis and vesicoureteral reflux. Cystoscopic evaluation revealed the presumed "bladder" to be a massively dilated prostatic urethra. The small dysplastic "true bladder" was found at the anterior surface of the prostatic urethra with massively dilated ureteral orifices. Temporizing diversion was performed in the form of bilateral cutaneous ureterostomies, with an ultimate plan for reconstructive bladder surgery. This case presents diagnostic challenges utilizing current modalities due to a massively dilated prostatic urethra in the rare case of bladder dysplasia.
