Paper Abstract

Meatal-hymenal deformity is a predisposing cause of the lower urological tract infection in females which is usually followed by sexual activity, menstruation or vaginitis. The urethral external orifice is usually narrowed owing to the deforming meatal-hymen. Morphologically, meatal-hymeneal deformity is classified into volcanic hymen and valvular hymen. Since May of 1985, 132 cases of meatal-hymenal deformity were treated with CO2 laser at a wavelength of 10.6 micrometers and at an output power of 20 w. A wedge shape incision was made above the urethral external orifice accompanied by regional hymen vaporization at the bottom or on both side. Periodic expansion of urethra and lavation with 1/2000 bromo-geramine solution followed. The value of the method is simple in operation, without complication, not necessary to be in charge and with a satisfying healing rate of 97 percent. In this study, we discuss the pathological changes causing the lower urological tract infection in females, the operating methods, theory and advantages of CO2 laser therapy.
