Urinary Lithiasis Secondary to Urethral Duplication: A Case Report

Urethral duplication is a rare congenital anomaly, mainly involving boys, although cases in girls have been reported. The majority of duplications of the urethra are asymptomatic and the discovery of this malformation can be done at any age. Diagnosis and determination of its type are based on urethrocystography with mid-void images, which helps to guide the surgical approach. The treatment is not yet well codified and the therapeutic attitude varies from one author to another. We report a clinical observation of a urethral duplication with a calculus in a six-year-old boy who underwent a partial urethrectomy of the supernumerary urethra in whom a lithotomy and a urethrectomy were performed via a suspension approach. This observation illustrates the possibility of urinary stone formation after partial urethrectomy of the supernumerary urethra.
