What does endoscopic surgery consist of?

Endoscopic surgery is a minimally invasive minimally invasive technique in which the interior of an organ or cavity is directly observed by means of an instrument called an endoscope, which is introduced through natural orifices. Different surgical procedures can be performed through this approach.

In the specific case of Urology, this type of surgery is grouped under the term Endourology (minimally invasive surgery inside the urinary tract).

What are the advantages of endourological surgery?

This technique has several advantages over conventional open surgery:

What urological procedures are performed by endourological surgery?

There are multiple surgical procedures performed with this minimally invasive technique:

In the surgery of renal lithiasis: Ureterorenoscopy, RIRS and percutaneous nephrolithotomy.

Ureterorenoscopy or RIRS (Retrograde Intrarenal Surgery) is performed through the use of a surgical instrument called ureteroscope, which can be flexible, rigid or semi-rigid. This is introduced through the urethra until it reaches the bladder and once there, it is moved up the ureter until it reaches the lithiasis, which has to be fragmented with a laser, or even the kidney. After surgery, a double J catheter is usually placed in the ureter for a few days after the procedure. The hospital stay ranges from 12 to 24 hours.

Percutaneous Nephrolithotomy (PNL) is indicated for the treatment of kidney stones larger than 2 cm. A small incision is made in the skin and through a surgical instrument called a nephroscope the stone is located, fragmented with a laser and then the lithiasic remains are extracted.

Endoscopic urethreotomy

In urethral surgery: Endoscopic urethreotomy

Endoscopic urethreotomy is an intervention for the treatment of urethral stricture.

Urethral stricture is a scar that narrows the tube through which urine is eliminated to the outside from the bladder (urethra).
The surgical technique consists of opening the narrowing with the blade of an endoscopic instrument called a urethrotome. After surgery, the urinary catheter is maintained for a period of time to maintain the caliber of the urethra. Usually, after removal of the catheter, it is necessary to perform urethral dilatations.

In bladder surgery : Transurethral resection (TUR) of the bladder.

Once the tumor in the bladder has been identified, the following procedure is performed Transurethral Resection of Bladder Tumor (TUR-BL). This technique is performed using an instrument called a resectoscope which has a loop at the tip and allows samples to be taken from the bladder and the tumor to be resected (removed) and the samples obtained to be sent to a pathologist for analysis.

Transurethral resection (TUR) of prostate gland

In prostate surgery : Transurethral resection (TUR) of the prostate gland .

Transurethral resection (TUR) of the prostate is performed using an instrument called a resectoscope that has a loop at the tip and allows the obstructive part of the prostate to be resected (removed) to leave a wide hole that allows for comfortable urination. The tissue obtained is sent to an anatomopathologist for analysis.

It is very important to individualize each case and offer the best treatment for each patient.
