UroLift system for relief of prostate obstruction under local anesthesia
Barkin Jack , Giddens Jonathan , Incze Peter , Casey Richard , Richardson Stephen , Gange Steven, MD Humber River Regional Hospital, University of Toronto, Toronto, Ontario, Canada
Many men with benign prostatic hyperplasia (BPH) forego therapy because they are dissatisfied with current treatment options. While surgical resection and ablation using many different forms of energy remain the reference standard for BPH treatment, many men seek a less invasive technique that will improve symptoms but not risk the complications associated with tissue removal. The Prostatic Urethral Lift opens the prostatic urethra with UroLift (NeoTract Inc., Pleasanton, CA, USA) permanent implants that are delivered under cystoscopic visualization. The implants literally 'hold open' the lateral prostatic lobes creating a passage through the obstructed prostatic urethra. Voiding and symptoms are significantly improved without the morbidity or possible complications following prostate resection. The entire procedure can be readily performed using local anesthesia. As with all new implant procedures, the technique has evolved with experience. The objective of this article is to describe the most current technique for the delivery of the UroLift implant in order to achieve maximal impact on symptom relief.

Initial North American experience with the use of the Olympus Button Electrode for vaporization of bladder tumors
Canter J. Daniel , Ogan Kenneth, Master A. Viraj, MD Department of Urology, Emory University School of Medicine, Atlanta, Georgia, USA
The current treatment standard of care for patients who present de novo or with a recurrent bladder tumor is transurethral resection of the bladder tumor (TURBT) using monopolar or bipolar electrocautery in the form of a 90-degree loop electrode, which has been used since its introduction in 1952. This intervention, accomplished transurethrally, is both diagnostic and potentially therapeutic for patients with bladder cancer, especially for low grade, non muscle-invasive bladder tumors. Although usually safe and sufficient, this technique can create technical challenges, especially in the dynamically changing spherical space of the bladder. Bipolar energy has been available for many years and has been readily adopted for the endoscopic treatment of benign prostatic enlargement. A further refinement on bipolar energy has been the recent introduction of the Olympus Button Electrode (Olympus, Southborough, MA, USA). Coupling bipolar energy into the Olympus Button Electrode not only harnesses the benefits of less thermal spread but also obviates many of the geometric challenges associated with loop electrodes during resection of either large or inauspiciously placed bladder tumors. In this article, we detail our initial experience vaporizing bladder tumors with the Olympus Button Electrode. Although still very early in our experience, we have been able to completely vaporize very large tumors as well as tumors located in difficult parts of the bladder to access with minimal blood loss and no bladder perforations. Furthermore, our ability to obtain adequate grade and stage information has not been compromised by using this vaporization technique.

Holmium laser enucleation of the prostate technique for benign prostatic hyperplasia
Kelly C. Douglas , Das Akhil, MD Department of Urology, Thomas Jefferson University Hospital, Philadelphia Pennsylvania, USA
Holmium laser resection of the prostate (HoLRP) was first described by Gilling et al in 1995. HoLRP has now evolved into holmium laser enucleation of the prostate (HoLEP) with the advent of the intravesical soft-tissue morcellator. The procedure involves anatomical dissection of the prostatic tissue off the surgical capsule in a retrograde fashion using a high-powered holmium laser followed by intravesical morcellation of the prostatic tissue. Some groups believe that the HoLEP procedure is the endoscopic equivalent to a simple open prostatectomy and may be superior to transurethral resection of the prostate (TURP) or even open prostatectomy. The objective of this article is to explain the techniques for holmium laser enucleation of the prostate (HoLEP).

Management of pelvic organ prolapse
Ahmed Faisal , Sotelo Tiffany, MD Pelvic Floor Center, George Washington University Hospital, Washington, DC, USA
Symptomatic pelvic organ prolapse can afflict up to 10% of women. Urinary incontinence, voiding dysfunction or difficulty possibly related to bladder outlet obstruction are common symptoms. Infrequently hydronephrosis or defecatory dysfunction can be seen. The management of pelvic organ prolapse (POP) should start with adequate assessment of all pelvic floor complaints. If a patient is not symptomatic, surgical intervention is usually not indicated. While the use of a variety of graft materials are available today including porcine, dermal and synthetic grafts, that are used in some surgical approaches to pelvic organ prolapse, other more conservative approaches may prove beneficial to many patients. This article describes our approach to the patient with pelvic organ prolapse.

GreenLight 180W XPS photovaporization of the prostate: how I do it
Zorn C. Kevin, Liberman Daniel, MD Department of Urology, University of Montreal Hospital Center (CHUM), Montreal, Quebec, Canada
Transurethral resection of the prostate (TURP) is the most common surgical intervention for benign prostatic hyperplasia (BPH), largely due to lower urinary tract symptoms refractory to medical therapy. TURP remains the gold standard for men with prostates sized 30g-80g, while open prostatectomy has been the preferred option for men with glands larger than 80g-100 g and those with other lower urinary tract anomalies such as large bladder stones or bladder diverticula. Unfortunately, these procedures have complications including bleeding (often requiring transfusion in 7%-13% of cases), electrolyte abnormalities (2% TURP syndrome), erectile dysfunction (6%-10%), and retrograde ejaculation (50%-75%). The overall incidence of a second intervention (repeat TURP, urethrotomy and bladder neck incision) has been reported in 12% and 15% of men at 5 and 10 years following TURP. Alternative therapies have been developed with the aim of reducing the level of complications while maintaining efficacy. These include microwave therapy, transurethral needle ablation, and a range of laser procedures (Holmium, Diode, Thulium and 532nm-Greenlight). Photoselective vaporization of the prostate (PVP), initially launched as a 60W prototype, was ultimately introduced to the urology community as a 80W system (American Medical Systems, Minnetonka, Minnesota, USA), has been the predominant device used in clinical trials. This 1st generation used an Nd:YAG laser beam passed through a potassium-titanyl-phosphate (KTP) crystal, halving the wavelength (to 532nm), doubling the laser’s frequency, and resulting in a green light. Outcomes have demonstrated a reduced frequency and severity of clinical complications, however it was limited to smaller prostate sizes. In 2006, the 120W lithium triborate laser (LBO), also known as the GreenLight HPS (High Performance System) laser was introduced. This laser utilizes a diode pumped Nd:YAG laser light that is emitted through an LBO instead of a KTP crystal, resulting in a higher-powered 532 nm wavelength green light laser while still using the same 70-degree deflecting, side firing, silica fiber delivery system. The HPS offered an 88% more collimated beam and smaller spot size, resulting in much higher irradiance or power density in its 2 predecessors (60W and 80W) with a beam divergence of 8 versus 15 degrees. The primary aim for this upgrade was to reduce lasing time and improve clinical outcomes while demonstrating the same degree of safety for patients. Limitations of the 120W system included treatment of large prostates greater than 80g-100g and increased cost related to fiber devitrification and fracture. In 2011, the 180W-Greenlight XPS system was introduced, not only with increased power setting to vaporize tissue quicker but significant fiber-design changes. Internal cooling, metal-tip cap protection and FiberLife (temperature sensing feedback), better preserve the integrity of the fiber generally producing a 1-fiber per case expectation. Initial personal experience with XPS has provided comparable outcomes related to morbidity, but with the opportunity to perform a more complete and rapid procedure. Published clinical data with the XPS is unfortunately lacking. The objective of this report is to detail our approach and technique for GreenLight XPS drawing on personal experience with both enucleation and vaporization techniques with various laser technologies along with having performed over 500 GreenLight HPS and 100 XPS procedures. In this regard, recommendations for training are also made, which relate to existing users of the 80W and 120W GreenLight laser as well as to new laser users.
