To remove a kidney stone stuck in your ureter, you may need to undergo Ureterorenoscopy or Retrograde Intrarenal Surgery (RIRS).
This procedure involves passing a long, thin telescope, known as a ureteroscope, through the urethra into your bladder. It is then moved up into the ureter where the stone is stuck.
The surgeon may either gradually remove the stone using an equipment, or they may use laser energy to fragment the stones into small pieces. The small pieces of stone can then be passed out in your urine.
Percutaneous nephrolithotomy (PCNL)
Percutaneous nephrolithotomy (PCNL) refers to an alternative procedure that could be used for removing larger stones. This procedure involves using a thin telescopic instrument or a nephroscope. An incision leading to your kidney is created in your back. The equipment is then passed through the incision into your kidney. The stone could be either pulled out, or broken into smaller fragments using laser or pneumatic energy.
Open surgery: It is very rarely performed nowadays.
Open surgery is usually recommended if there is an extremely large stone or an abnormal anatomy. This procedure involves creating an incision in your back to gain smooth access to the ureter and the kidney. The kidney stone can then be easily removed.
Ureteric Stone Treatment
Treatment is always recommended if the ureteric stone fails to pass down the ureter or begins to cause significant symptoms. The surgical treatment of ureteric stones involves:
Ureteroscopic removal of stone (URS)
Urinary stones present in the ureter, particularly hard stones or stones that cannot be treated with ESWL, can be treated using laser. Ureteroscopic removal of stone is a procedure which is used to treat stones situated in the middle and lower ureter.
A ureteroscope or a small, fiberoptic instrument is inserted through the urethra and bladder into the ureter. The ureteroscope enables the urologist to directly visualize the stone present in the ureter.
While small stones are removed using a specialized stone basket, large stones are broken into smaller pieces using a laser or a similar device. A stent may be placed in the ureter for some days following the treatment in order to allow healing and prevent blockage caused by inflammation or spasm.
