title: The contribution of urethrocystoscopy to evaluation of lower urinary tract dysfunction in women.
abstract: The aim of this study was to determine whether the evaluation of lower urinary dysfunction with urodynamics and urethrocystoscopy provides unique information that is missed by urodynamics alone. Eighty-four women underwent multichannel urodynamics and urethrocystoscopy. Retrospective analysis included evaluation of the relationships between lower urinary tract lesions and risk factors using chi2 and Fisher's exact tests. Urethrocystoscopic findings changed the diagnosis and management in 6 patients. New urethrocystoscopic findings included papillary transitional-cell carcinoma, cystitis glandularis, an intravesical suture and a urethral diverticulum. Clinical parameters were not predictive of these findings. Urethrocystoscopic findings also contributed to the final diagnosis in 10 patients with intrinsic sphincter deficiency. Considered alone, maximum urethral closure pressure < or =20 cmH2O had a sensitivity of only 20% and a positive predictive value of 40% for this diagnosis. Urodynamics without urethrocystoscopy would have missed important diagnoses in 19% of women. Urethrocystoscopy and urodynamics complement one another, and both have a role in the evaluation of women with lower urinary tract dysfunction.
