Ureter Procedures

The ureters are tubes that carry urine from the kidneys to the bladder, and ureter pain is usually evidence of ureter blockage, perhaps because of a ureteral stone or some other disturbance requiring ureteroscopy (looking into the ureter) and the placement of a ureteral stent. If less invasive measures are deemed ineffective to treat the patient’s specific case of ureteric condition, then Dr. Choonara might advise open ureteric surgery to alleviate soreness and discomfort of the upper urinary tract.


Pyeloplasty for Uteropelvic Junction Obstruction

Pyeloplasty is a procedure that is performed for the treatment of Uteropelvic Junction (UPJ) Obstruction. UPJ Obstruction is a condition in which the flow of urine out of the kidneys into the ureter is blocked. The obstruction may be caused by an infection, as well as kidney stones, scar tissue or as the result of a congenital defect.

During the procedure, Dr Choonara will make an incision below the ribs, and remove the obstructed section of the ureter. The healthy part of the ureter is then carefully attached to the renal pelvis. Dr Choonara will place a stent to drain fluid from the kidney until the site of surgery has healed.

Ureteroneocystostomy for Vesico-ureteric Reflux and Stone Disease

Ureteroneocystostomy refers to a procedure in which the ureter is reimplanted in the bladder. Dr Choonara may recommend the surgery for the treatment of vesico-ureteric reflux. Vesico-ureteric reflux (VUR) is a condition in which the valve between the ureters and the bladder does not function as it should. The condition can cause urine to flow backwards, sometimes reaching as far back as the kidneys, causing severe damage. During ureteroneocystostomy, Dr Choonara will disconnect the ureters from the bladder and reattach them at a more suitable angle. The procedure may also be recommended if you have been diagnosed with stone disease.

Ureteric Stenting for Stone Disease

If you have been diagnosed with urinary problems, such as stone disease, Dr Choonara may recommend ureteric stenting. During the procedure, Dr Choonara will insert a stent (a thin tube) into the ureter with the use of a special instrument known as a cystoscope. The cystoscope has a camera attached to its end, allowing Dr Choonara to view the inside of the body and make sure that the stent is placed in the correct location. The stent resolves obstructions in the urine flow between the kidneys and the bladder, and relieves any uncomfortable symptoms associated with the condition.

Ureteroscopy for Stone Disease

If you have displayed symptoms of kidney stones, Dr Choonara may recommend a ureteroscopy, which is a procedure in which the upper urinary tract is examined with an instrument known as a ureteroscope. The ureteroscope is a tube with a light and camera attached. He will insert the ureteroscope through the urethra and bladder and into the ureter. Because he can view the inside of the body, Dr Choonara will confirm diagnosis of the kidney stones. In some cases, he will then perform lithotripsy and stone fragment retrieval procedures.
