Ureteroscopy is a common urological procedure administered in patients having urinary tract and bladder related disorders. Ureteroscopy is recommended for patients having kidney stones. The movement of the renal stones is monitored by urologists. Ureteroscopy is a minimal invasive endoscopic procedure predominantly involving the urethra, upper urinary tract and the urinary bladder.
A flexible or rigid form of telescope is passed through the urethra in order to view the affected region. The procedure is performed under general or spinal anesthesia. The telescopic examination of the ureter and associated organs reveals the exact location of the stone and also other disorders of the system. Other diagnostic tests such as X-rays, CT scan, EKG along with laboratory parameters like urinalysis and complete blood count also help in the effective determination of the underlying condition. This technique is usually followed by the other associated procedures such as lithotripsy in which laser beams are administered to the affected region to dissolve the calculi(stone) or to clear urinary tract strictures. The entire procedure may last from 30 minutes to three hours and patients are advised to stay in the hospital for a day.
The urologist uses the uterescope to remove small kidney stones while larger stones need to be broken up before removal. A kidney stone that has escaped from the kidney and got stuck in the ureter can be pushed back into the kidney. Here it has to be broken into smaller pieces to aid removal. A stent is usually left in place to allow the kidneys to pass the urine to the bladder. This is kept for a few days in case there is swelling and subsequent difficulty in draining the kidney of the urine.
Complications and risk factors
Hematuria happens because of the insertion of the ureteroscope. It usually subsides within 3 days. Antimicrobial therapy is given if hematuria is followed by an infection. Other possible complications are:
Stent associated pain
Perforations caused because of stents
Lower back pain
Urethral stricture or perforation
