👉 A cystotome is a surgical tool or instrument used for inserting a catheter into the bladder to collect urine. It is typically used during an emergency procedure, such as in a hospital setting, where a patient's bladder is blocked by a urinary tract infection (UTI). During this process, a catheter is inserted through the urethra and directed into the bladder. The catheter collects urine from the bladder, which can then be collected for further use or discharged into a drainage bag.
