Ureteroscopy (URS)

Ureteroscopy (URS) is a form of minimally invasive surgical operation the usage of a small telescope that is handed via the urethra and into the ureter to dispose of a stone. Often the stone requires fragmentation with a laser which then allows the smaller fragments to removed with a grasping tool. Only approximately 10-15% or urethral stones require surgical intervention. URS is about 95% a success in putting off stones in the decrease ureter and approximately 85-90% successful in treating and getting rid of stones within the upper ureter and kidney.


URS is an outpatient process which means that patients usually cross home the same day. The system is generally performed the usage of wellknown anesthesia but once in a while local anesthesia may be used effectively in choose instances. A preoperative antibiotic is commonly given to prevent infection. The manner can range in duration-occasionally as short as 20 minutes for small un-complex stones, to one (1) or longer for large, more complicated stones.


After the technique, patients are awakened within the operating room and taken to the healing room. Once all health facility discharge criteria are met, sufferers are allowed to head domestic. A buddy or member of the family is required to accompany you home after the process. There are no barriers on physical sports upon discharge. We often endorse taking the time off from paintings after your method.


A urethral stent is a soft hole tube that acts like a straw to allow urine to skip from the kidney down the ureter into the bladder. It is very commonplace to have a stent positioned into your ureter on the end of a URS. Stents are located for a selection of motives, all to help preserve the ureter open after the manner. A “string” is generally left attached to the stent and dangles out the urethra. The string is used to do away with the stent 2-5 days submit-operatively.

It is not unusual to have some side outcomes associated with the stent such as irritative urinary signs (frequency and urgency to urinate) or ache inside the kidney/flank region without delay or shortly after urinating. These symptoms resolve right away after the stent is removed.

Occasionally we propose that a stent continue to be the ureter for as much as 4 weeks, specially if there has been any diploma of damage to the ureter both from the stone or the manner to cast off the stone. If that is completed, a string is normally NOT left attached to the stent and elimination of the stent will require passage of a small bendy telescope into the urethra and bladder (cystoscopy) within the office to comprehend and cast off the stent.


As with any surgery, complications can occur, albeit they are uncommon. Examples of complications from URS consist of, but aren't confined to:

  • failure to remove stone
  • perforation of the ureter
  • harm to different structures inclusive of bladder, urethra, ureter, kidney
  • urinary contamination
  • need for extra techniques
  • scar or stricture of ureter (<5% will require surgical repair)
  • blood in the urine
  • instant surgical repair of an injured ureter (<<1% cases)

Most patents have no problems after URS. However, if you should have any questions, develop excess pain, nausea or vomiting not relieved with medications, chills and fever >101 F, inability to urinate, bloody urine with massive clots or any other uncommon issues, you need to contact us enterprise hours or report to the ER if after hours.
