Laser surgery for prostate and urinary stones

The use of laser equipment in urology allows us to solve multiple diseases in a minimally invasive way using state-of-the-art technology.


The calculations or stones can appear both in the kidneys, the ureters or the bladder. In the past, open surgeries with large incisions were required to treat stones. Today, flexible endoscopic equipment is used to approach stones through the urethra, without the need for any type of incision. By using the Holmium laser, the stones will be pulverized and then urinated in the form of grit.

This type of surgery reduces postoperative pain and guarantees a much faster recovery of the patient.

In many cases, a thin catheter, called a Double J catheter, is left inside to avoid pain and postoperative complications, which is removed a few days later in a very simple outpatient procedure. Only in cases of large kidney stones, another type of surgery called Percutaneous Nephrolithotomy is required in which a small incision of less than 1 cm is made in the patient’s back.


Prostatic hyperplasia is a benign growth of the prostate. It is produced with advancing age and by the influence of the normal testosterone of every man. This growth produces progressive obstruction of urine outflow. Its most frequent symptoms are:

  • Decreased micturition caliber
  • Increased frequency of urination.
  • Sensation of incomplete emptying.
  • Burning to urinate.
  • Dribbling at the end of urination.
  • Effort to urinate.
  • Getting up frequently while sleeping to urinate.
And in the worst case, complete inability to urinate (urinary retention) requiring placement of a catheter through the urethra to achieve bladder emptying.Prostate hyperplasia can be treated with different types of medications, but often the patient will need surgery.In the past, it was necessary to open the patient’s abdomen to perform the surgery. Today, laser surgery for prostate hyperplasia is performed through the urethra, without the need to make any incisions in the patient. It consists of the use of a special type of Thulium laser (different from the one used in urinary calculi), by means of which all the prostate tissue that has grown is eliminated, leaving only the prostate capsule. The tissue is then removed from the body using another special device called a morcellator. All prostate fragments will then be sent to the pathologist for study to determine the type of prostate cells.Performing minimally invasive surgery reduces the risks associated with surgery, decreases bleeding, hospitalization time, postoperative pain and allows a faster reintegration into daily life. Results are even more durable with minimally invasive surgery.There are very few urologists trained to perform this type of surgery in Colombia. Dr. Wadskier formed a work team with Dr. Armando Juliao and between them they have the most experience in the entire coastal region in this type of procedure.
