Prostatic aperture resulting from visual laser ablation: classification system based on follow-up endoscopy.
To study the evolving prostatic aperture created by visual laser ablation (VLAP), we performed 38 video-endoscopies in 24 men with prostatism at various intervals 2 weeks to 1 year after treatment. Complete healing was generally observed within 3 to 4 months, never before 6 weeks; and in some patients, tissue sloughing was still apparent beyond 6 months. By review of the cystoscopic findings and video hard copies, three independent observers classified the healed prostatic apertures with great uniformity into one of four categories: (I) minimal change (lateral lobes still meet in midline throughout gland length) (N = 3); (II) minor aperture (opening less than 50% of cystoscopic field over less than 50% of gland length) (N = 5); (III) major aperture (opening more than 50% of cystoscopic field over more than 50% of gland length) (N = 11); and (IV) full ablation (nearly complete replacement of lobar configuration with a general concavity) (N = 5). Clinical outcomes (symptom scores, uroflow rates) matched with follow-up cystoscopic categories but not with any other readily identifiable measures. The four-category system proved to be simple, reproducible, and clinically relevant. If a standardized tissue aperture is the ultimate aim of new methods to ablate the prostate, the proposed system for classifying the aperture could have a considerable future application.
