  • Anatomic GreenLight laser vaporization-incision technique for benign prostatic hyperplasia using the XPS LBO-180W system: How I do it

    Law W. Kyle, Elterman S. Dean, Cash Hannes, Rijo Enrique, Chughtai Bilal, Misrai Vincent, Zorn C. Kevin, MD Department of Urology, University of Montreal Hospital Center CHUM, Montreal, Quebec, Canada

    For men experiencing lower urinary tract symptoms (LUTS) refractory to medical therapy, there have been numerous developments in the treatment options offered for benign prostatic hyperplasia (BPH) in the recent years. Transurethral resection of the prostate (TURP) has remained the reference standard for men with prostates sized 30 cc-80 cc, while open prostatectomy is universally guidelines-recommended in the absence of enucleation, for men with prostates larger than 80 cc-100 cc. While these techniques are effective, they have the potential for bleeding complications requiring transfusions, electrolyte abnormalities such as TURP syndrome, and often require prolonged hospitalization. GreenLight photoselective vaporization (GL-PVP) with the XPS LBO-180W system offers a minimally invasive treatment that can be carried out on essential any sized prostate gland. In addition, the GL-PVP procedure can be done as a same day discharge surgery requiring no overnight hospital admission and allows patients to continue any necessary anti-coagulants given the significantly reduced risks of bleeding complications or TURP syndrome. In 2005, the anatomic vaporization-incision technique (VIT) using the XPS LBO-180W system was described to address larger prostate volumes. VIT combines principles of traditional GL-PVP and enucleation techniques to identify the reference surgical capsule early-on into the surgery and resect portions of prostate adenoma without the need for tissue morcellation. Early studies comparing anatomic VIT to standard PVP outcomes demonstrated significant improvements of IPSS and uroflowmetry parameters, along with statistically significant greater PSA reduction at 6 months, particularly in prostate volumes greater than 80 cc. The objective of this article is to detail our surgical approach to the anatomic GreenLight laser vaporization-incision technique using the XPS LBO-180W system, based on extensive personal experience with both enucleation and vaporization techniques using various laser technologies. Standardization of the VIT based on proper cystoscopy, knowledge of prostate anatomy with preoperative ultrasound, and routine technique is essential to developing consistent, reproducible and optimal surgical outcomes.

  • The Rezūm system - a minimally invasive water vapor thermal therapy for obstructive benign prostatic hyperplasia

    Cantrill H. Christopher, Zorn C. Kevin, Elterman S. Dean, Gonzalez R. Ricardo, MD Urology San Antonio, San Antonio, Texas, USA

    Benign prostatic hyperplasia (BPH) and accompanying lower urinary tract symptoms (LUTS) sits in the top ten prominent and costly disease conditions in men over 50 years of age. In the United States it is the most common diagnosis made by urologists for men 45 to 74 years of age. Twenty percent of the population will reach 65 years of age or older by 2030, and those over 85 years will represent the fastest growing segment of our population. The prevalence of symptomatic BPH increases proportionally with the aging population. It is estimated that BPH now affects 6% of the male population worldwide. Moreover, in Canada, the estimated BPH prevalence is more than 1 million men aged 50 years and older. Among the various surgical treatments, Rezūm water vapor thermal therapy has been developed as a unique, rapid and reproducible minimally invasive surgical treatment exhibiting safe and early effective relief of LUTS/BPH. The targeted prostate tissue ablation is amenable to all zones of the prostate including intravesical median lobes. We present our experiences with this technique, which can be quickly performed under local anesthesia in an office setting.

  • How I do it: Balloon tamponade of prostatic fossa following Aquablation

    Aljuri Nikolai, Gilling Peter, Roehrborn Claus, MD PROCEPT BioRobotics Corporation, Redwood Shores, California, USA

    Since its first report in the 1870s, control of bleeding after transurethral resection of the prostate (TURP) has remained a concern. Foley?s initial report of a urinary catheter involved placement of the balloon into the prostatic fossa following TURP. Removal of prostate tissue with a high-velocity saline stream (Aquablation) is a recently reported alternative to TURP. As Aquablation is heat-free, alternatives to non-thermal hemostasis were sought to optimize the procedure. We report use of a balloon catheter in the prostatic fossa after Aquablation as a post-resection hemostatic method.

  • State of the art: Advanced techniques for prostatic urethral lift for the relief of prostate obstruction under local anesthesia

    Walsh Patrick Lance, MD Eisenhower Medical Center, Rancho Mirage, California, USA

    Benign prostatic hypertrophy (BPH) affects an estimated 60% of men over the age of 50 and 90% of men over the age of 80. The prostatic urethral lift (PUL) is a safe and effective office-based procedure that is used worldwide for the treatment of BPH in men who are dissatisfied with medications due to side effects or lack of efficacy or don?t want to have a transurethral resection of the prostate due to the side effects and invasiveness of the procedure. In 2012 Barkin et al, published the standard technique for the delivery of the Urolift implant. The objective of this article is to describe the current state of the art advanced techniques for the delivery of the UroLift implant.

  • Treating male retention patients with temporary prostatic stent in a large urology group practice

    Roach M. Richard, MD Advanced Urology Institute, Oxford, Florida, USA

    Men with either chronic or temporary urinary retention symptoms are common patients treated in a urology practice. Both indwelling and intermittent catheterization are widely used to treat this condition. These approaches are associated with significant complications including infection and reduced quality-of-life. Infection is a target for quality improvement and cost reduction strategies in most care settings today. We use a temporary prostatic stent (TPS) to address these issues in our practice. In this report, we describe our approach to patient selection, sizing, placement and follow up of 214 TPS placed in 56 men with chronic or temporary urinary retention in an office setting. With the first stent placement, average indwelling time was 27 days. Thirty-two patients had multiple stents placed. Replacement was performed routinely and was generally required because underlying comorbidities precluded surgery. In these patients, an average of six stents were placed (range 2-18) with average dwell times of 31 days. Symptomatic urinary tract infections (SUTI) occurred in only 6 of 214 TPS placements (2.8%), resulting in an incident rate of 0.93 SUTI per 1,000 TPS days. TPS is a safe and efficacious means of alleviating symptoms of urinary retention. TPS does not share the same infection risk profile or quality-of-life drawbacks associated with urinary catheters; this makes TPS use relevant as a urinary catheter alternative or when a urinary catheter is not recommended.
