Ureteroscopy (Ureteral stone surgery)

Overview

This procedure uses a small telescope (ureteroscope) that is passed from the outside through the urethra, the bladder and then into the ureter to access the area that has either a stone, cancerous lesion or requires a stent for urine and stone fragment drainage. In some cases a rigid scope is used. However, a flexible scope can be utilized at the surgeon’s discretion.

Indications

Ureteroscopy is beneficial as a diagnostic tool. This procedure can be utilized to locate a possible cause for the patient’s history of positive urinalysis findings and/or abnormal radiographs. Ureteroscopy is indicated for the treatment of a male or female patient with a confirmed stone that will not pass on its own or a patient with a tumor or condition that requires a biopsy to be performed.

Analysis

If a stone is retrieved during the ureteroscopy procedure, and if ordered by the physician, the stone will be sent to the lab for chemical analysis. This will be helpful in determining follow-up treatment, and will help your physician advise you on how to prevent stones from coming back in the future.

If a biopsy specimen is recovered during the ureteroscopy procedure, we will send it to the lab for analysis by a pathologist. This is done to provide the physician with further information to effectively plan a course of treatment.

Types of Ureteroscopy Procedures

Ureteroscopy with stent placement

The stent placement is performed during the ureteroscopy. The placement of a ureteral stent is completed at the same time to alleviate any obstruction of the ureter because of stone, internal tumors, or external compression from other disease processes. Stents placed in the ureter serve several purposes. In the case of a kidney stone being broken up by a laser, it provides a protective lining for larger stone fragments to pass without damaging the ureter. Stents maintain dilation if the ureter swells from instrumentation during ureteroscopy. This will allow urine to pass unobstructed, consequently alleviating discomfort. Stents also serve as a support during the healing process.

Ureteroscopy with stone manipulation/extraction

When ureteroscopy is performed for the treatment of a stone in the ureter, the stone can be manipulated into position with instruments for extraction and a stone basket. The surgeon inserts a small basket through the ureteroscope, grasps the stone and removes it.

Ureteroscopy with laser lithotripsy

On occasion, the stone may be too large to remove with a stone basket and must be crushed into smaller pieces for removal. The stone is struck with a laser beam which breaks it into smaller pieces. Stone fragments can then be removed with the stone basket or will flow out naturally with urine.

Ureteroscopy with removal of a tumor or biopsy

If ureteroscopy is performed for tumors, the ureteroscope is used as a conduit for laser and biopsy forceps to remove the tumor.

Although rare, a biopsy can be performed during a ureteroscopy. Some conditions call for a brush biopsy to be performed to gather tissue from inside the ureter for microscopic evaluation.
