Urinary Lithiasis Secondary to Urethral Duplication: A Case Report

“…A number of hypotheses have been put forward to explain the embryopathogenesis of urethral duplication, but none of these alone can explain all the anatomical forms of this malformation. Some authors have suggested a delay in the formation of the balanic lamina in relation to the portion of the urethra originating from the urogenital sinus, which first reaches the dorsal part of the genital tubercle; for Mollard, cited by several authors, for Mollard, cited by several authors, this anomaly results from an embryological disturbance identical to that of bladder exstrophy and true epispadias and, finally, for Williams and Kenawi, an anomaly of median fusion of lateral mesoblastic flows at the level of the cloacal membrane [4] [10] [11].…”

“…The treatment of the supernumerary urethra is not yet well codified and the therapeutic indication varies from one author to another; the only consensus is that the asymptomatic forms are respected [5] [11]. On the other hand, in the symptomatic forms, the treatment is essentially surgical, which consists of total excision of the supernumerary urethra, at the neckline of the penis if there is a dorsal curve of the latter.…”
