In this article, we have reviewed the scope of surgically induced damage to the lower urinary tract. Preventative and reparative techniques have been presented. As pelvic surgeons become more confident in their efforts to safeguard the urinary tract, the chance of an unrecognized injury causing morbidity will diminish.
One hundred consecutive neurologically normal women complaining of urinary incontinence underwent standing incremental retrograde medium-fill water cystometrograms on two different days followed by sitting and standing continuous retrograde medium-fill water urethrocystometry on a third visit between November 1987 and February 1989. Studies were done to assess the reproducibility, sensitivity, specificity, and predictive values of a simple cystometer. Standing incremental, retrograde cystometry was found to be relatively inexpensive, simple, reproducible, and sensitive. The two cystometrograms yielded similar results in 84% of the patients. The sensitivities were found to be 84.3 and 90.2% for the first and second cystometrograms, respectively. Using both cystometrograms together, we were able to detect detrusor instability with a sensitivity of 92.3% and to predict its absence with a negative predictive value of 86.7%. Detrusor instability was found in 64% of these patients. Based on these results, it was concluded that when multichannel urodynamics are not available in a high-prevalence population, standing retrograde incremental water cystometry done on two occasions may offer the physician an accurate alternative for the diagnosis of detrusor instability.

This article reviews the common causes for urinary urgency and frequency in women. The normal aging process and its effect on lower urinary tract function is reviewed. A stepwise evaluation and appropriate diagnostic tests are described. In addition, a wide variety of therapeutic options are discussed.
