Laser safer than conventional prostate peeling

Modern laser techniques such as greenlight laser therapy or the diode laser method are far more gentle than conventional peeling (TURP) of the prostate gland. Laser treatment is also superior to TURP in terms of safety. This was confirmed by a study recently published in the renowned scientific journal "Urology".

Constant urination, a weak stream of urine and unpleasant dripping - which for many men becomes a nightmare, is usually due to a benign enlargement of the prostate gland. She meets almost every second man over 50 and even every 80-year-old. In benign prostatic hyperplasia (BPH), the glandular tissue of the prostate grows in the area of the urethra. Due to the narrowing of the urethra, the strength of the urine stream decreases and residual urine remains in the bladder. If the drugs do not lead to the desired success or if repeated urinary tract infections or blood infections occur in the urine, surgery is usually required to eliminate the urinary flow disorder.  The standard procedure for the surgical treatment of benign prostate hyperplasia is still the classical peeling (transurethral prostate resection/TURP). A special endoscope is inserted into the urethra and the glandular part of the prostate is hollowed out with an electric loop around the urethra. Although this method has been significantly improved in recent years thanks to medical progress, complications can occur,"explains Dr. Pedram Derakhshani, urologist at the West German Prostate Center. In view of the still existing bleeding risks in particular, laser procedures such as greenlight laser therapy or the diode laser method have been used for a number of years in addition to the classic peeling-off procedure,"said the Cologne urologist. Instead of the electrical current, excess tissue is evaporated by means of laser energy. The advantage of this procedure is that it is almost bleeding-free.

Less complications

The results of a recent study1 of 108 patients who were treated with either a greenlight laser or TURP show that laser therapy is superior to conventional peeling in terms of safety: While there were no significant complications during laser treatment, eight patients in the TURP group had to undergo an operation-related blood transfusion and three patients had a so-called transurethral resection syndrome. Flushing fluid enters the bloodstream via opened vessels. The result is a change in the electrolyte situation and thus an enormous strain on the circulation. Five patients had a perforation of the prostate capsule. However, the laser procedure also offered clear advantages in terms of the duration of the hospital stay:"A urethral catheter is usually placed for one night after the laser therapy and thus shortens the hospital stay from one week to two days. In some cases, outpatient care is even possible,"says Derakhshani.  Due to the obvious advantages in the side-effect profile, patients with an increased surgical risk and those who have to take anticoagulants benefit from the laser procedure. With the high-performance Evolve 150 diode laser, even patients with a large prostate can be treated without any problems.
