A patient of 11 years old was referred to the service for acute urinary retention, following repetitive failure to insert urethral catheter two weeks after trauma to the genitalia during a football match. He complained of difficult and painful micturition and eventually urinary retention. A cystostomy was placed in the emergency room. He was circumcised at age 3 and was treated for recurrent UTI in the past. On physical examination, the urethra meatus was normal; there was a hard, round, palpable mass in a tender penile urethra (Figure 11). A scout film of the pelvis showed an image of a urethral stone (Figure 12(a)). Opacification of lower tract during VCUG confirmed the obstruction from the stone but no reflux (Figure 12(b)). There was marked leukocyturia at 17000/mm3. Citrobacter koseri was isolated from the urine. We removed the calculus via urethrotomy (Figures 13 and 14). The two urinary catheters were kept on the abdomen after dressing (Figure 15). Postoperative follow-up was normal.
