Frequently Asked Questions About TURP Resectoscope Systems

Yes, many modern transurethral resection of the prostate (TURP) instrument sets include both a cutting loop and a coagulating loop. These dual-loop configurations allow surgeons to efficiently perform tissue resection and hemostasis during the same procedure.

The cutting loop is primarily used to excise excess prostate tissue with precise back-and-forth slicing motions through the resectoscope. Once a section of tissue is removed, the surgeon may switch to the coagulating loop, which delivers controlled high-frequency electrical current to cauterize blood vessels and manage bleeding.

This seamless transition between cutting and coagulation enhances surgical efficiency, reduces operative time, and improves intraoperative visibility by minimizing blood flow into the surgical field. Some advanced systems even integrate both functions into a single electrode, allowing mode switching without instrument changes.

The integrated irrigation system is a critical component of TURP surgery, serving multiple essential functions that contribute to patient safety and procedural success.

• Visualization Enhancement: A continuous flow of irrigation fluid (commonly glycine, sorbitol, or saline in bipolar systems) clears blood and tissue debris from the surgical site, providing the surgeon with a clear view of the prostate and surrounding anatomy.
• Electrolyte Management: The choice of irrigant helps maintain electrolyte balance, especially important in monopolar systems where non-conductive fluids are used to prevent current dispersion. In bipolar systems, normal saline can be used, reducing the risk of hyponatremia (TURP syndrome).
• Temperature Regulation: The fluid helps cool the surgical site and electrodes, preventing thermal injury to surrounding tissues.
• Edema Reduction: By maintaining consistent pressure and washing out inflammatory mediators, irrigation helps reduce intraoperative swelling and postoperative discomfort.
• Bladder Distension: Proper irrigation pressure keeps the bladder expanded, facilitating access and manipulation of the resectoscope.

Monitoring irrigation fluid absorption is crucial, as excessive uptake can lead to fluid overload and electrolyte imbalances—making real-time tracking an important part of patient management during prolonged procedures.

The cutting loop is the primary tool used to resect (remove) obstructive prostate tissue during TURP surgery. It is attached to the distal end of the resectoscope and functions through a combination of mechanical movement and high-frequency electrical energy.

Once inserted through the urethra and positioned under direct visualization via the resectoscope’s optics, the loop is energized and moved in a controlled back-and-forth sawing motion. This action simultaneously cuts prostate tissue and coagulates small blood vessels, depending on the energy settings used.

The cutting mechanism relies on high-voltage alternating current (in monopolar systems) or localized bipolar energy that passes through the loop, enabling precise tissue dissection layer by layer. As the tissue is severed, it floats into the bladder and is later evacuated using irrigation suction at the end of the procedure.

Surgeons carefully plan the resection pattern—typically working from the bladder neck toward the verumontanum—to ensure complete removal of obstructive tissue while preserving critical anatomical structures and minimizing complications such as urethral injury or retrograde ejaculation.

Bipolar TURP technology represents a significant advancement over traditional monopolar systems, offering several clinical and safety benefits:
