  Reentrant superconductivity has been observed in the candidate spin-triplet
superconductor UTe$_2$ as a function of the magnetic field applied along the
hard axis. Resistivity measurements have shown, a broadened superconducting
transition appears near the minimal $T_c$, highlighting the importance of
superconducting fluctuations in this regime. We present a phenomenological
study assuming a field-driven first-order transition between two
superconducting states. We show that with quenched randomness,
inhomogeneity-enhanced superconducting fluctuations near the transition could
naturally account for both the reentrant superconductivity as well as the
broadened superconducting transition.
