Book an appointment with Dr Nikola PetrovićA urinary catheter is a thin, flexible tube passed through the urethra into the bladder. A small balloon at the end keeps it in the bladder, and urine drains into a bag. A catheter is used when a patient cannot pass urine on their own, after some operations or in some long-term conditions, as assessed by the doctor. The Foley catheter is the most common type, and silicone catheters are usually used when the catheter needs to stay in longer.
A long-term catheter is changed at intervals set by the urologist. The Maja Hospital urology price list has separate items for Foley catheter change and silicone catheter change. When the doctor decides the catheter is no longer needed, it is removed: the balloon is emptied and the catheter is pulled out. If you cannot pass urine after removal, contact a doctor without delay.
A J-J stent (JJ stent, ureteric stent) is a thin, soft tube placed from the kidney to the bladder that temporarily keeps urine draining freely from the kidney, for example after stones are broken up, when the urologist decides it is needed. It is removed by a short procedure through the urethra. The urology price list has separate items for J-J stent insertion, insertion on both sides under local anaesthetic and J-J stent removal in women and in men.
The stent is temporary. The urologist sets the removal date, and a stent left in too long can become coated with stone deposits, cause infection and damage the kidney. So book the removal appointment and write it down.
Medicine or a solution is put into the bladder (instillation) on the urologist's recommendation. The urologist decides which preparation is needed and how many times the procedure is repeated. The urology price list lists it as administration of medicine into the bladder.
At Maja Hospital, Vizantijski bulevar 39 in Niš, urinary catheters are inserted, changed and removed by a urologist. Appointments are booked by phone.
The Maja Hospital urology price list has items for catheter insertion, silicone catheter insertion, Foley catheter change, silicone catheter change and catheter removal. All are in the price table on this page.
It depends on the type of catheter and your condition. The urologist decides when it is changed.
No. A J-J stent is a thin tube placed inside the body that temporarily connects the kidney and the bladder, while a urinary catheter drains urine from the bladder into a bag.
Within the time set by the urologist. A J-J stent is temporary and must not stay in the body longer than that, because a stent left in too long can become coated with stone deposits, cause infection and damage the kidney. Book and write down the removal date, and if you miss it, contact the urologist.
