The Selfconsistent Quasiparticle RPA (SCQRPA) will be presented, which has been developed to study the effects of fluctuations on pairing properties of finite systems. It has been applied to nuclei at finite temperature and angular momentum. Several issues will be reported, including 1 - the smoothing of superfluid-normal phase transition, 2 - the pairing reentrance effect (thermally assisted pairing in hot rotating nuclei), 3 - an improved odd-even mass difference for the extraction of nuclear pairing gap, 4 - the description of nuclear level densities by using SCQRPA solutions embedded in the canonical and microcanonical ensembles, 5 - the deviation from the universal quantal limit of the shear viscosity over the entropy in superfluid nuclei at finite temperature. Perspectives of further extensions of SCQRPA will also be discussed.
