A total of 24 boys sustaining a simultaneous pelvic fracture and posterior urethral disruption was observed from the time of injury through puberty. Average length of followup was 6 years. In contrast to the adult, in whom the urethra is invariably injured at the prostatomembranous junction, the posterior urethral disruptions in the prepubertal patient were at 3 distinct locations: 1) supraprostatic in 4 patients, 2) transprostatic in 4 and 3) prostatomembranous in 16. Prolonged followup through puberty in these children revealed that the frequency of complications was significantly higher for urethral injuries proximal to the prostatomembranous region compared to those at this latter site: impotence 75% versus 31%, intractable strictures following repairs 75% versus 12% and urinary incontinence 25% versus 0%. In summary, the prognosis of children who sustain a posterior urethral disruption should be based on the location of the injury and must remain guarded until the individual attains a postpubertal status.
