[Ureteral perfusion test in the urodynamic evaluation of the upper urinary tract: critical review and case study]

The authors report on their clinical experience with the use of Whitaker test in 38 patients (27 men, 5 women; age 3 months-66 years). Clinical applications of ureteral pressure-flow test are extensively reviewed. A standardized method with simultaneous recording of bladder pressure and combined video-pressure-flow study are basic points to be considered in order to obtain more objective data.
