These lenses are made of soft optical glass and should only be cleaned with soft lint rather than cotton gauze which might the basic skills of transurethral resection 93 scratch them erectile dysfunction treatment in thailand cheap viagra vigour 800 mg line. Water may also not have been wiped off the lens of the telescope or the camera before the camera is attached to the telescope erectile dysfunction in young adults buy 800 mg viagra vigour. In conventional irrigating systems the most common cause for want of clear vision is obstruction of the water inflow (Fig erectile dysfunction treatment diet cheap 800mg viagra vigour. This happens on a boringly regular basis, so keep an eye on the bag from time to time and warn the nurse that you need more fluid well in advance. In continuous flow systems there may be imbalance between the negative pressure in the suction and the rate of inflow of the irrigating fluid. Whatever system of irrigation is used the inflow will stop when the bladder is so full that it can take no more. Since this means that the pressure inside the bladder has risen, this is a state of affairs that should never be allowed to occur. This situation can occur with continuous irrigation, although it is much less likely to do so. Most surgeons develop a sixth sense when the bladder is nearly full and when it is time to empty it out, and most resectoscopes begin to leak before this critical moment has been reached. From time to time a chip of prostate or bladder tumour will be stuck to the lens or jammed between loop and sheath. The lens should be cleaned using the jet of irrigating fluid or a piece of sterile lint. Use a broken wooden orange stick such as used for microbiological cultures: the wood does not scratch the optical glass. The telescope will probably have to be returned to the manufacturer to get rid of water vapour. The tissue which is removed during transurethral resection is therefore in theory identical with 1,2 the tissue removed by an enucleative open operation (Fig. The various techniques of transurethral resection differ only in the order in which the bulk of tissue is removed. Two plans are described here: neither is in the least bit original and no particular preference is claimed for either. The important thing is that you should have a plan and stick to it, or else you will certainly get lost. In each method the resection begins with a preliminary urethroscopy and cystoscopy, careful lubrication of the urethra, and an internal urethrotomy if there is the slightest tightness of the resectoscope sheath (see page 70). Establishing the landmarks the landmarks in transurethral resection are the same whether you remove much tissue or only a little: the distal limit to the resection is the verumontanum, which stands like a lighthouse just proximal to that special region of the prostatic urethra which contains the supramembranous intrinsic component of the external sphincter (Fig. This is a ring of elastic tissue, striated and unstriated muscle, quite distinct from and above the levator 3 ani. Make sure that you have seen the sphincter: bring the resectoscope out beyond it, cut off the water flow and see it contract like the anus in its characteristic way (Fig. As you do this you will note an even more important feature: as the sheath of the resectoscope passes out Transurethral resection 96 Figure 6. Recognizing this sensation is of great importance: it is as important as for the blind man to know what it feels like to step off the pavement onto the road. The proximal limit to the resection is the ring of muscle at the neck of the bladder. Having identified the verumontanum and the external sphincter, the next step is to find the ring of muscle at the bladder neck in the posterior middle line. The purpose of defining this proximal limit is to prevent you from inadvertently encroaching on the trigone and ureteric orifices. In some patients there is virtually no adenoma in the region of the middle lobe and the first loopful of tissue reveals muscle fibres immediately under the urothelium (Fig. In others it is necessary to resect a considerable volume of adenoma before the bladder neck is exposed (Fig. Once these fibres have been laid bare, they are left alone for the time being, even though it may be necessary to return to the bladder neck and trim more of it away at the end of the resection.
