Set of 8, Liston's cylindrical dilating sound for bladder and urethra
Date
Circa 1880
Description
Set of 8, Liston's cylindrical dilating sound for bladder and urethra, gauge 1 to 10, with violin-shaped handle.
What is referred to this context as sounds are actually urethral probes or dilators; a sound is actually a solid instrument inserted into the bladder to make a noise (or "sound") when it touches a stone, hence confirming the diagnosis of a bladder stone.
