[Urethral duplication with giant calculus. Case report]

the urethral duplication is an uncommon congenital anomaly. We presented a case of male patient with congenital urethral duplication with a giant calculus in the accessory urethra.

male patient 23 years old with sensation of tumor and pain in the lower pelvis and base of the penis with decrease of the urinary spurt and final dripping. There was edema in the penescrotal area; a hard tumor can be touched, painful to movement. The urethrography and cistoscopy showed urethral duplication type IIB according to the classification of Effman without communication with bladder, it had rooted before the fossa navicular in a blind-ending which was hidden at the bulbar urethral where the giant calculus was located. A surgical procedure was done to remove it. It measured 3 x 2 cm. The patient had a satisfactory recuperation.

the presence of a giant calculus in the urethral is a strange situation and when it does happen, one must suspect malformation in such structure. There was no surgical correction done to the urethral duplication. The etiological factor for the formation of the giant calculus seems to be the urinary stasis, it is usually present in the urethral duplication. The surgical treatment must be individualized for each patient according to type of anatomical duplication.
