Objectives:
We present a new technique of transurethral prostatic enucleation. METHODS. We use an Olympus resectoscope with two electrodes; one has a button or "mushroom" shape to vaporize and enucleate, and the other one the shape of a conventional "cutting loop electrode"to resect. With the button-shaped electrode, we vaporize transversally at the level of the veru montanum, extending the dissection towards the lateroapical lobes, looking for the capsular plane. Once it is found, we ascend vaporizing up to the 3 and 9 in the clock following the capsular plane. Subsequently, we vaporize longitudinally the anterior commissure and keep going down to join the previously vaporizatized area. Then enucleation is achieved by pushing the adenoma with the button-shaped electrode, from distal to proximal, at the capsular plane level. Before the enucleated lobe falls inside the bladder, we can proceed, with the help of the conventional cutting loop electrode, to its resection, which is very fast and bloodless. If there is middle lobe, enucleation is initiated with it, performing two lateral grooves lengthways down to the veru montanum. RESULTS. We have carried out 45 procedures since October 2011, with excellent functional results. Prostate volumes range between 40-120 gr, with an operating time of 30-90 minutes. Hospital stay was 24-48 h. and the catheter is removed in 4-5 days. Blood transfusions were not needed in any case, and we have not recorded complications within this first year of follow-up. CONCLUSIONS. This technique makes possible the enucleation of the adenoma with a good haemostasis control. It also provides a good visualization of the capsular plane. Vaporization of the prostatic tissue is similar to the use of other energy forces. We don't need to use a "morcellator" to extract the enucleated prostatic tissue. It is an economical and easily reproducible procedure, with a short learning curve.
