RESUMEN
Endourethral dissection of valvular cusps was carried out by means of an urethrotome in 34 boys with Type I and III valves of the posterior urethra. The indications for and the techniques of the dissection on depending on the type of the valve are discussed and measures for preventing complications are suggested. Endoscopic, radiological, and urodynamic methods of examination of the lower urinary tract determined the therapeutic tactics and help in evaluation of the efficacy of the operative treatment. The method allows correction in patients with valves to be performed in one stage in the compensated stage of the disease and after preliminary derivation of urine in the decompensated stage. The authors recommend optic urethrotomy for the treatment of children with valves of the posterior urethra.
