The newly developed rotation resectoscope is a new product system by Richard Wolf. More than 50 years' experience in the development of medical high-tech products and product systems is manifest in the new rotation resectoscope. Particularly worthy of mention is the full rotation of the working elements through 360° for continuous irrigation and intermittent sheaths, thus enabling a considerably easier and more efficient application.

A special new feature is also the thin sheath profile. It reduces friction in the urethra. In this way trauma is considerably minimized. The lubricant embeds itself in the smal grooves for extended lubrication. 

Resection in saline (NaCl) is mainly used in urology for prostate and bladder resection. The procedure is also used in gynecology for myoma and endometrium resection as an additional alternative to monopolar resection. The key difference is the use of saline (NaCl) instead of glucose solution. Saline is used as an irrigation medium and conductor, contributing to even greater patient safety because a neutral electrode no longer needs to be connected to the patient’s body. The current does not flow through the patient’s body but is conducted to the electrode instead.

Resection benefits from the generation of plasma to achieve outstanding cutting power.

A short outline of the process is provided below:

• An electric current heats the saline solution and tissue via the loop
• Bubbles are generated as the saline evaporates
• The current ionizes the gas bubbles to generate plasma
• The plasma ignites and the loop is illuminated bright yellow
• The tissue evaporates and the loop electrode starts cutting

This method offers the following main advantages:

• shallow coagulation
• minimal in-depth thermal damage
• no impairment of histologic quality
• reduced irritation of the urethra (both thermal and mechanical)
