Ureteric (DJ) Stenting
It is a procedure in which a small tube is placed in the ureter. Ureter is the tube which carries urine from the kidney to the urinary bladder. It may be placed to prevent or treat obstruction in the ureter. The stent is placed with the aid of a cystoscope under flouroscopic guidance. The ends of the stent have a coil to prevent it from moving out of place; hence the name double J stent stent.
Indications
Ureteric stents are placed to ensure patency of the ureter which may be compromised by a kidney/ureteric stone or by a surgical procedure on the upper urinary tract. After an endoscopic surgery for kidney/ureteric stones, ureteric stents are usually kept to prevent obstruction of the ureter by small stone fragments or blood clots. It is generally a temporary measure and the stent is removed after few days.
Indwelling stents may be kept longer in disease processes which cannot be cured eg. inoperable tumors in the vicinity of ureter. This is required to prevent damage to the kidney due to the uretetic obstruction.
Side effects
Common symptoms after ureteric stent placement are urgency, frequency, blood in urine, burning micturition and pain in the flank during micturition. The doctor will prescribe you medicines to decrease the severity of these symptoms. These symptoms disappear after stent removal.
While the stent is in place, patients can continue with most normal daily activities; however the stent may cause some discomfort during strenuous physical activity.
Stent removal
This is done as an outpatient procedure using a cystoscope. It takes only a few minutes. Most patients tolerate stent removal using only a topical anesthetic placed in the urethra. Patients can eat normally before and after the procedure and can leave the hospital immediately after the procedure.
