Conclusion

Tin filter-based unenhanced CT protocol can significantly reduce radiation exposure compared with standard-dose abdominal CT protocol. Latest iterative reconstructions allow reduction of background noise and optimize image quality. Hence, tin filter-based CT protocol is suitable for the follow up of urolithiasis after RIRS, reducing cumulative dose.
