Introduction: Urethra is not a frequent localization of lithiasis. Many studies report clinical cases or limited series. The objective of this study was to show the frequency of this pathology in our practice. Patients and Methods: It was retrospective descriptive study of the patients treated for urethral lithiasis between June 1, 2012 and June 30, 2016 in our structure. Results: 106 cases of urethral lithiasis were diagnosed and treated. This localization accounted for 14, 54% of the urolithiasis and 3, 13% of urological intervention in the period. The mean age was 14, 24 years(1-68 years). The sex ratio was 7, 15 in men favor. The reason for consultation was acute urinary retention in 66, 98% of cases, the liathiasis was palpable in 83, 02% of cases. The treatment consisted of a cystolithotomy after discharge of the lithiasis in the bladder in 74, 53% of cases, instrumental extraction in 21, 70% of cases and the urethrolithotomy in 3, 77% (n=4) of cases. The urethra was permeable after ablation of lithiasis in all cases. Conclusion:The lithiasis impacted in the urethra is not rare in our practice. It must be evoked before acute urinary retention of children and adolescent.
