Risk factors for ureteral obstruction and the diagnostic value of the "cysto-under-tension" technique at the time of uterosacral colpopexy.

In this large cohort study, older age was associated with higher odds of obstruction at the time of colpopexy while a higher BMI might have been protective. The "cysto-under-tension" technique overall may not be that useful in detecting ureteral obstructions but has high negative predictive value.
