Photoselective vaporization of the prostate (PVP)

Photoselective vaporization of the prostate (PVP) is a minimally invasive procedure that uses a special high-energy laser (e.g., GreenLight PVP™ Laser) to vaporize excess prostate tissue and seal the treated area.
.
The procedure is performed on an outpatient basis in a hospital or surgical center and may be performed under local, spinal, or general anesthesia.
.
PVP takes between 10 and 30 minutes to perform, depending on the size of the prostate and patients are usually discharged within a few hours.
.
The type of laser used in PVP is delivered to the prostate through an endoscope (device that consists of a tube and an optical system) that is inserted into the urethra. The procedure prevents damage to surrounding tissue and minimizes side effects such as pain, blood in the urine (hematuria), and swelling.
.
Many patients do not require a catheter after PVP, and those who do typically are catheterized for less than 24 hours. Patients are advised to avoid strenuous exercise for 2 weeks following the procedure and can usually resume regular activities the next day. PVP provides immediate and long-lasting results comparable with other minimally invasive procedures.
