Prostate laser surgery is used to relieve moderate to severe urinary symptoms caused by an enlarged prostate, a condition known as benign prostatic hyperplasia (BPH).
All lasers use concentrated light to generate precise and intense heat. Prostrate Laser surgery removes excess prostate tissue by:
Ablation. The laser melts away excess tissue. Example: KTP Greenlight laser
Enucleation. The laser cuts away excess prostate tissue. Example: HoLEP
There are different types of prostate laser surgery, such as:
Photo selective vaporization of the prostate (PVP). A laser is used to melt away (vaporize) excess prostate tissue to enlarge the urinary channel.
Holmium laser ablation of the prostate (HoLAP). This is a similar procedure to PVP, except that a different type of laser is used to melt away (vaporize) the excess prostate tissue.
Holmium laser enucleation of the prostate (HoLEP). The laser is used to cut and remove the excess tissue that is blocking the urethra. Another instrument, called a morcellator, is then used to chop the prostate tissue into small pieces that are easily removed.
Holmium laser enucleation of the prostate (HoLEP) is a minimally invasive treatment for BPH. The surgeon uses the laser to enucleate the prostate gland tissue, leaving just the capsule in place. HoLEP is performed transurethrally, using a holmium laser to separate the plane between the prostate gland tissue and the prostate capsule. This prostate laser surgery allows complete resection of all adenomatous tissue, minimizing the need for future re-treatment.
Kidney stones (renal lithiasis, nephrolithiasis) are small, hard mineral deposits that form inside your kidneys. The stones are made of mineral and acid salts.
Facts about kidney stones
Retrograde intrarenal surgery (RIRS) is a procedure for doing surgery within the kidney using a viewing tube called a fiberoptic endoscope.
In RIRS the scope is placed through the urethra (the urinary opening) into the bladder and then through the ureter into the urine-collecting part of the kidney. The scope thus is moved retrograde (up the urinary tract system) to within the kidney (intrarenal).
RIRS may be done to remove a stone. The stone is seen through the scope and can then be manipulated or evaporated by a laser probe or grabbed by small forceps, etc.
The new Holmium: YAG laser delivers very short, intense pulses of infrared light that can break down any form of stone, no matter what kind, into tiny fragments that can be flushed out or excreted in urine. It’s less invasive than surgery, meaning patients recover more quickly and are less likely to experience complications.
Percutaneous nephrolithotomy is a procedure used to remove kidney stones from the body when they cannot pass on their own. This procedure uses small telescopes and instruments inserted through a small incision in your back to remove the kidney stones.
Percutaneous nephrolithotomy is used most often for larger stones or when other procedures, such as extracorporeal shock wave lithotripsy or ureteroscopy, are unsuccessful or not possible.
