How long do I have to have the double J catheter in place?

The length of time a person will need to wear a double J catheter will depend on the complexity of the procedure. Typically, after ureteroscopic surgery or retrograde intrarenal surgery, the time ranges from one week to 10 days. However, if the surgery is more complex, it may be necessary to wear the catheter for about 15 days, and this period may be extended to 21 days.
