JJ Stent (removal of kidney stones)

your doctor has recommended to insert a

stent between your kidney and your

bladder the medical term for this is a

double J stent the stent allows drainage

of urine from the kidney into the

bladder by temporarily relieving any

blockage caused by a stone in the ureter

or an internal swelling outside of the

ureter the renal pelvis is the area

where the kidney attaches to one of the

ureter 's urine flows from the kidney

through the ureter x' into the bladder

when emptying your bladder the urethra

transports the urine from the bladder to

the outside of the body this animation

shows a blockage in the ureter caused by

a stone urine is unable to flow from the

kidney to the bladder causing congestion

and sometimes pain

the procedure is usually done under

general anesthesia a tube with a tiny

optic camera is inserted through the

urethra into your bladder the bladder is

inspected and the ureter ik opening is

located a contrast study may be

performed to assess the urinary tract

and to locate the obstruction x-ray

images can now clearly outline the

ureter and the obstruction a so-called

guide wire is introduced through the

camera into the kidney the double J

stent is inserted over this guide wire J

shaped curls are present at both ends of

the stent to hold the tube in place

x-ray is used to check that both ends

are in place in the kidney and the


the stent is later on removed or is

sometimes used as a temporary

intervention before the removal of the

stone with another procedure you will be

discharged from the hospital when you

have been able to empty your blood

sufficiently and you have no fever or

other complaints
