Abstract

From October 1990 through July 1991, 187 women who complained of urinary incontinence underwent investigation in the department of urology, especially urodynamically, compared with 42 women with female urethral syndrome as control group. The following results were obtained ; mean functional urethral length was 3.1+/-0.9cm and mean maximal urethral closure pressure was 80.2+/-2.4cmH2O in genuine stress incontinence patients. But each results of female urethral syndrome were 3.6+/-0.7cm and 121.1+/-3.8cmH2O, respectively, and were higher than those of genuine stress incontinence (p <0.05 ). The incidence of positive pressure equalization of genuine stress incontinence was higher than that of control group, as 85.6% and 14.3% (p<0.05). The findings of uroflowmetry and cystometry showed within normal limits in genuine stress incontinence and poor voiding pattern in female urethral syndrome. Conclusively. urodynamic study was important for diagnosis and follow up of genuine stress incontinence.
