Relative usefulness of physical examination, urodynamics and roentgenography in the diagnosis of urinary stress incontinence.

Stress urinary incontinence is a common problem in women. Accurate diagnosis of this condition is necessary for successful surgical treatment. Currently, many tests are popular. The relative value of these tests, in terms of usefulness, accuracy and practicality, has not been tested in the past. With this aim, we have compared the results from three of the most commonly performed tests, namely physical examination, urodynamics and roentgenography. It is our opinion that physical examination in the standing position is the simplest and most accurate test. Cystometrogram is important, although the yield is small. We do not advise the routine use of urethral pressure profile. For accurate determination of anatomic deformity, roentgenographic examination is the most accurate test.
