2 For visual laser ablation of the prostate a side-firing laser is used to treat the prostatic urothelium and underlying tissue, which leads to eventual sloughing of the prostatic urothelium and underlying tissue, and opening of the prostatic channel. During the postoperative period the patient typically experiences severe storage

voiding symptoms. On the other hand, with interstitial laser coagulation a similar low power laser is applied deep to the prostatic urothelium in an effort to decrease the lower urinary tract symptoms.2 Due to lack of long-term durable outcomes, high production costs and results no better than those of other MIST, this office based technology has fallen out of favor. However, despite declining

use of MIST in the U.S. in the last 5 years, is there still a role in our therapeutic armamentarium for them? It should be noted R428 supplier that this decrease in MIST has been largely driven by declining BIBF 1120 purchase reimbursement as well as less than optimal long-term sustainability of efficacy. One of the newest devices to fill the gap between medication and surgical intervention is the prostatic urethral lift device known as the UroLift® system (fig. 1, NeoTract, Inc., Pleasanton, California). The UroLift system is a nonablative technique that uses solely mechanical compression to open the prostatic urethra. We discuss the advantages and potential limitations of this procedure being performed in an office setting. The initial experience with this system required a 25Fr cystoscope, which precluded routine use Bumetanide in the office, but as the system was refined, PUL can now be done with a rigid 20Fr cystoscope. With the patient in the lithotomy position, the cystoscope is placed into the bladder (fig. 2, a), and a custom delivery device, preloaded with a suture, is deployed in the anterolateral position to compress lateral tissue ( fig. 2, b). A handheld

delivery device is fired with transurethral sutures at the anterolateral lobes of the prostate. A 19 gauge, 33 mm needle is fired, traverses the capsule and then anchors itself to compress the prostate. For small prostates (ie 60 gm) 2 to 4 sutures are needed and more sutures are required for larger prostates ( fig. 3). An absolute contraindication for the procedure is a prominent median lobe.4 In addition, patients with other concomitant indications for surgical intervention, including recurrent urinary tract infection or hematuria, bladder stones or renal insufficiency, should not undergo the procedure. Finally, men with a history of acute urinary retention or concern/diagnosis of detrusor underactivity or decompensation may also require more formal removal of obstructing tissue.
