Effect of tadalafil on renal resistivity and pulsatility index in partial ureteral obstruction.

Introduction: To investigate the effect of tadalafil on Resistivity Index (RI) and Pulsatility Index (PI) in partial unilateral ureteral obstruction (PUUO).

Methods: Twelve New Zealand rabbits were assigned into two groups. Baseline renal Doppler ultrasonography (USG) was performed in all rabbits.
