title: [Valves of the posterior urethra in children].
abstract: The paper reports the analysis of 62 cases of posterior urethra valves treated from 1988 to 1993 in the Central Children's Hospital of Russia. The patients' age ranged from 6 months to 14 years. The patients were examined with the use of urethroscopy, urethrography and urodynamic tests providing accurate differential diagnosis of the urethral valves and other infravesical obstructions. Transurethral electroresection of the valvular cusps proved most effective treatment. There exists high probability of self cure of upper urinary tract complications after the transurethral resection (65%). The expectant policy should be followed in relation to vesicoureteral reflux and megaureter (3-6 and 6-12 months, respectively). The exceptions comprise the cases of the above reflux with marked lateralization, ectopy and exposure of ureteral ostia which are more effectively managed by simultaneous valvular transurethral resection and endoscopic submucous injections of teflon paste underneath ureteral ostia. The study of the prevalence of chronic renal failure suggested a conclusion on its equal occurrence in different age groups.
