[The role of lubrication in transurethral electrical resection].

Transurethral resection inevitably leads to thermal as well as mechanical stress on the urethra, and it is important to reduce both. This can be achieved by using a suitable lubricant. Measurements in saline irrigation fluid as long as 30 years ago showed that the distribution of high-frequency current in the region of the urethra during transurethral electrical resection depends on the different resection systems, i.

New bipolar resection device for transurethral resection of the prostate: first ex-vivo and in-vivo evaluation.

Background And Purpose: Bipolar resection systems for transurethral resection of the prostate (TURP) offer some advantages over conventional monopolar devices. As both the active and the return electrode are placed on the tip of the resectoscope, current flow is locally limited, and negative effects caused by the current flow through the patient's body in the monopolar array can theoretically be reduced. Furthermore, bipolar resectoscopes use 0.

Electrocautery: principles and practice.

We explain the basic physics of transurethral resection of the prostate (TURP). Modifications of electrodes or high-frequency units that should improve TURP are discussed. Finally, we introduce Coagulating Intermittent Cutting (CIC), which is a TURP using a modified high-frequency generator.

Coagulating intermittent cutting: improved high-frequency surgery in transurethral prostatectomy.

Purpose: Despite the good long-term results of transurethral resection of the prostate (TURP), intraoperative blood loss and TUR syndrome produce morbidity. Thus, TURP is still considered invasive therapy. Many minor invasive alternative treatment modalities have been developed in recent years.

Coagulating intermittent cutting. Improved high-frequency surgery in transurethral prostatectomy.

Objectives: Transurethral prostatectomy (TURP) is the gold standard in surgical therapy of symptomatic bladder outlet obstruction. TURP is characterised by immediate treatment success, due to the removal of obstruction combined with a long-lasting improvement of symptoms and voiding parameters. In spite of good long-term results of TURP, intraoperative blood loss produces morbidity.
