TUR (Trans-Urethral-Resection) electrodes are used for the TUR-P (transurethral resection of the prostate) and the TUR-B (transurethral resection of the bladder).
It is a part of the HF (High Frequency) surgery.
The increase in the size of the prostate is called benign prostatic hyperplasia (BPH).
It happens to middle-aged and elderly men.
This increase compresses the urethral canal to cause partial or sometimes complete obstruction of the urethra which interferes the normal flow of urine.
At the end this can lead to complete urinary retention.
The TUR-P is the most common surgery to overcome this problem.
The results are good and because of improved techniques and less complications it is still the "golden standard".
The surgeon inserts a resectoscope (a kind of endoscope) into the urethra.
In the resectoscope is a little wire loop with a long thin shaft (the resection electrode). The resectoscope is connected to an HF-Generator and if needed power runs through the electrode and the loop.
The power that runs through the loop has a cutting and coagulating (blood sealing) effect.
The surgeon removes piece by piece of the obstructing tissue from the inside of the prostate. Through the optic of the resectoscope he controls his work.
The cutted tissue is flushed out at the end of the operation.
After the operation a kind of cavity is inside the prostate, allowing the urine to flow freely again.
Beside of the TUR-P, resection electrodes are also used in Gynaecology
for removing myomas etc. in the bladder and uterus area.
Depending on the indication, beside of the loop type also other types (ball, roller knife,) are used. Especially for vaporization these types are preferred to the loop type.
The resection electrodes from medfein are available in all common types and fit into the resectoscopes of different manufacturers.
