Is bladder cycling useful in the urodynamic evaluation previous to renal transplantation?

Objectives: To evaluate the usefulness of bladder cycling (BC) in differentiating between urodynamic abnormalities due to reversible bladder dysfunction and those due to preexisting lower urinary tract (LUT) abnormalities, and to determine if BC increases the diagnostic yield of urodynamic investigations (UIs) in these patients.

Methods: Eleven patients with oligoanuria (<300 ml/day) were evaluated with complete UIs. All cases showed low compliance (mean 6 ml/cm H2O) and low cystometric capacity (mean 146 ml) and were placed in a BC program.
