Transurethral enucleation of benign prostatic hyperplasia.

A prostatic detaching blade for a new endoscopic method has been devised for transurethral resection of the prostate along the cleavage plane at the surgical capsule. After partial resection of the adenoma with the loop the remaining adenoma, except for a portion at the bladder neck, is detached from the surgical capsule under direct vision with the detaching blade. The remaining adenoma then is removed by the electric loop down to the detached surgical capsule. This method of resection has been performed in 200 patients with improvement of symptoms in all. Detachment of the adenoma along the surgical capsule always is possible, thereby defining the depth of resection and minimizing the risk of capsular perforation compared to standard transurethral prostatectomy.
