Video transurethral resection. Report of 200 cases.

Two hundred transurethral resections of the prostate (TURPs) were performed using a controlled continuous flow (CCF) resectoscope attached to a video camera by direct-beam coupler. Standing comfortably, the surgeon used a video monitor as the source of judgment for manipulating the loop. Data obtained were statistically similar to those obtained from 400 previous resections using the same resectoscope by the conventional viewing method. TURP can be performed safely, more efficiently and more comfortably with the CCF video technique.

Video transurethral resection using controlled continuous flow resectoscope.

A video camera, attached by direct-beam coupler to the controlled continuous flow (CCF) resectoscope, is used to aid in the performance of transurethral resection (TUR). A television monitor becomes the source for judgment in guiding the resectoscope loop. The surgeon stands during the TUR to watch the image from the resectoscope lens, as projected on the video monitor screen, to decide where to cut tissue and fulgurate blood vessels. Fifty cases of transurethral resection of prostate (TURP) performed by the video method with the CCF resectoscope are compared with 400 TURP cases performed by the conventional method of looking through the scope using the same instrument. Resulting data from the video method were statistically similar to that obtained from the conventional method. The video method was a safe and effective means of visualizing the surgical field during TURP.

Noninvasive transvesical pressure monitoring using controlled continuous flow resectoscope.

This is a review of 400 cases performed with a controlled continuous flow (CCF) resectoscope which incorporates the use of a noninvasive transvesical pressure monitor. Two series of 200 cases each are compared. The results indicate that the second group of cases performed more recently, had a lower incidence of CVP elevation and serum sodium change. An alteration in surgical technique using the CCF may be responsible for the improved outcome in the second set of cases.

Videoprostatectomy.

Videoprostatectomy is discussed. A few cases have been performed, but many more need to be done to determine the safety of this procedure.

Controlled continuous flow (CCF) resectoscope. Report of 200 cases.

Controlled continuous flow (CCF) is a new balanced pumping system which has been designed for the resectoscope. The system is controlled by an intravesical pressure sensor. Upper limits of pressure are set, and the input flow is shut off electronically if it is attained. Flow rates of up to 1,000 ml/minute can be achieved for maximum clarity of vision. Two hundred cases have been performed with the CCF resectoscope. Various parameters were measured and are presented. The results indicate that TURP can be performed safely and more efficiently with the CCF resectoscope.
