Case Discussion
CT features of bladder calculi.
Bladder calculi occur either from migrated renal calculi or urinary stasis. Bladder calculi can be divided into primary and secondary stones:
- Primary: stones formed in sterile urine, usually renal calculi which have migrated down into the bladder
- Secondary: stones form de novo in the bladder or from concretions on foreign material (e.g. urinary catheters)
