Pericatheter encrustations: an unusual cause of a retained Foley catheter

Urethral catheterisation is a common bedside procedure in hospitals. After they have served their purpose, indwelling Foley catheters can be removed by deflating their balloon. The incidence of a retained Foley catheter, however, is not uncommon, failure to deflate the intravesicular balloon being the most common reason. Causes of retained Foley catheters are many and the method to deal with each varies with the inciting cause. Pericatheter concretion or encrustation, an unusual cause of difficulty in removal of the catheter, is often difficult to recognise and hence is prone to faulty management. We report a case of a patient with a retained Foley catheter due to pericatheter encrustations; multiple attempts to remove it were made before the patient presented to our hospital. The case is being reported for the unusual location of retention, and the associated diagnostic and therapeutic dilemma.
