Over the years, new practices for prostatic hyperplasia therapy have been developed and existing methods have been improved. Not so long ago, a new method of electrosurgical tissue removal, called bipolar resection, was developed. When bipolar resection is conducted, the electric current does not flow through the entire patient’s body during tissue resection, but is limited only to the distance between electrodes. This is the main difference from monopolar resection treatment. This method is particularly important for transurethral resection in patients with cardiac diseases and significant prostate volume (more than 80 cm3).

As of today, the Karl Storz and Olympus companies are the main representatives and competitors present on the market with their bipolar resectoscopes and components. Today we are going to take a look at the corresponding equipment introduced by Olympus.

On the market, Olympus offers equipment consisting of the ESG 400 high-frequency generator, OES ProPDD and OES Pro resectoscopes, and a set of TURis 2.0 loops (transurethral resection in saline).

The ESG 400 new generation high-frequency electrosurgical generator provides strikingly powerful bipolar resection while utilizing a large loop electrode, and as a consequence, significantly increases productivity and reduces surgery duration.

The OES ProPDD and OES Pro (TURis 2.0) resectoscopes offer a new standard and approach to prostate and local forms of bladder cancer resection. Conducting transurethral resection in saline significantly reduces the risk of developing TUR syndrome and obturator nerve entrapment. The OES Pro resectoscope length is 194 mm, which provides access even to distant anatomical structures. The OES ProPDD resectoscope is equipped with photodynamic diagnosis technology (PDD) which allows doctors to differentiate bladder tumors with higher probability and conduct efficient resection.

Olympus offers a wide range of TURis 2.0 electrodes for transurethral resection. These electrodes are quick and easy to install, have a self-cleaning function, and quick tissue vaporization feature, significantly reducing the duration of the surgery.

Consequently, we can come to the conclusion that while conducting endoscopic transurethral surgical measures on large prostate glands, bipolar technology utilization is an alternative to more invasive procedures and monopolar resection for patients with significant operative risk. It is an important developmental direction for equipment manufacturers as well.
