Abstract
INTRODUCTION Thulium laser VapoEnucleation of the prostate (ThuVEP) is an evolving surgical technique for BPH. Most studies have focused on outcomes in small to médium sized prostates and have originated from Europe and Asia. We sought to describe our experience with ThuVEP for very large prostates in a North American cohort. MATERIALS AND METHODS From December 2010 to October 2014, 25 men underwent Thu-VEP using the CyberTM® (Quantastem, Italy) thulium laser, all with prostate volume >75mL. Data collected included patient demographics, comorbidities, intraoperative parameters, complications, and post-operative outcomes including maximum flow rate (Qmax), post-void residual (PVR), International Prostate Symptom Score (IPSS), and quality of life score (QoL) in one year of follow-up. Statistical analysis was done using Wilcoxon signed-rank test. RESULTS At baseline, mean age was 70±9 years and prostate size was 163±62g. Most patients (84%) were in retention and 10 (40%) patients were on anticoagulation. Seven (28%) patients went home the day of surgery (mean hospital stay: 1.2±1.2d). There were 2 intraoperative complications (8%), both cystotomies related to morcellation. Nine patients (36%) experienced a complication, all within 30 days. There were no Clavien III complications. Significant improvements were seen in Qmax, PVR, IPSS, and QoL score at each time interval to 12-months following surgery (all p<0.05). Of 21 patients initially in retention, all were voiding at last follow-up. CONCLUSIONS Our findings suggest that ThuVEP is an effective treatment for BPH in patients with large prostates with sustained results for one year.

Abstract
In 2005, the high power thulium laser was introduced for the surgical treatment of benign prostatic obstruction. It has several properties that confer theoretical advantages over other lasers used for the same indication, such as technical versatility and a relatively small zone of thermal damage. Studies using the 70-150 W thulium laser systems demonstrate good efficacy of these procedures with low morbidity and few complications even in higher risk patients. Different techniques have been employed to treat the prostate with this technology, including enucleation, vapoenucleation, vaporization and resection. Comparative studies have been published comparing thulium laser prostatectomy to monopolar transurethral resection of prostate (TURP), bipolar TURP and holmium laser enucleation of prostate (HoLEP). In this review we discuss the current literature on the safety and efficacy of various thulium techniques for the treatment of benign prostatic hyperplasia and examine comparative studies.

Abstract
INTRODUCTION The thulium laser was introduced in 2005 for the treatment of benign prostatic hyperplasia (BPH). Enucleation studies from outside North America show comparable efficacy and lower morbidity to transurethral resection of the prostate. A few studies exist describing outcomes of vaporization, the most commonly used technique for urologists. We present our 3-month outcomes of thulium laser vaporization of the prostate (ThuVP). MATERIALS AND METHODS From December 2010 to October 2013, 68 men underwent ThuVP using the 150 W CyberTM(®). Data were collected on demographics, comorbidities, intraoperative measures, complications, serum parameters, maximum flow rate (Qmax), postvoid residual (PVR), International Prostate Symptom Score (IPSS), quality-of-life (QoL) score, and prostate-specific antigen. Patients were evaluated at 1 week, 1 month, and 3 months postoperatively. Nine patients were excluded for known prostate cancer. RESULTS The mean age was 66±10 years, with a mean prostate size of 57±30 mL. At baseline, the mean IPSS was 19.9±8.0, QoL score was 4.5±1.1, Qmax was 5.2±4.5 mL/sec, and PVR was 220±397 mL. The mean laser time was 35±18 minutes, and energy used was 234±139 kJ. Forty-seven (78%) patients were discharged the day of surgery. No blood transfusions were administered with a mean drop in hemoglobin of 0.7±0.8 g/dL (p<0.05). There were no Clavien grade≥III complications within 30 days of surgery. Six (10%) patients were diagnosed with urinary tract infection. Significant improvements from baseline were seen in Qmax, PVR, IPSS, and QoL score. All 15 patients who were in retention were voiding at the last follow-up. CONCLUSIONS Thulium laser vaporization of the prostate appears to be a safe and effective outpatient technique for the treatment of BPH with durable outcomes at 3 months.

Abstract
INTRODUCTION The objective was to determine the prevalence of, and factors that predict, detrusor underactivity (DU) in patients presenting with incontinence or lower urinary tract symptoms (LUTS) following radical prostatectomy (RP). We also determined the prevalence of bladder outlet obstruction (BOO) and detrusor overactivity (DO) in this population. METHODS Patients who underwent urodynamics post-RP were identified. Detrusor underactivity was defined as a maximum flow rate (Qmax) of ≤15 mL/s and detrusor pressure (Pdet) Qmax <20 cmH20 or maximum Pdet <20 cmH20 during attempted voiding. Abdominal voiding (AV) was defined as sustained increase in abdominal pressure during voiding. Bladder outlet obstruction and DO were identified using the Abrams-Griffiths nomogram and the International Continence Society criteria. Univariate logistic regression was used to determine factors predicting DU. The following factors were analyzed: age, year of RP, procedure type (minimally-invasive surgery [MIS] or open), postoperative radiation, nerve-sparing, clinical stage, biopsy Gleason grade and interval between RP and evaluation. RESULTS Between 2005 and 2008, 264 patients underwent urodynamics post-RP. Detrusor underactivity was observed in 108 patients (41%; 95% CI 35%, 47%), of whom 48% demonstrated AV. Overall, BOO and DO were present in 17% (95% CI 12%, 22%) and 27% (95% CI 22%, 33%), respectively. On univariate analysis, only MIS RP was predictive of DU (univariate odds ratio 2.05 for MIS vs. open; p = 0.009). CONCLUSIONS Detrusor underactivity and AV are common in patients presenting for evaluation of incontinence or LUTS following RP. The etiology of DU in this setting is likely related to the surgical approach. Because DU may affect the success of male incontinence treatment with the male sling or artificial urinary sphincter, it is useful to document its presence prior to treatment. More studies are needed to elucidate the influence of DU on treatment success for male urinary incontinence following RP.

Abstract
OBJECTIVE We evaluated 5-year safety, efficacy and prostate volume data from BPH patients treated with finasteride or dutasteride. METHODS A retrospective analysis of 378 consecutive men treated with 5α-reductase inhibitor monotherapy between January 2004 and September 2009 (197 on finasteride and 211 on dutasteride) in a single clinic was performed. Efficacy assessments included International Prostate Symptom Score (IPSS), peak urinary flow rate (Qmax), postvoid residual urine volume (PVR), prostate-specific antigen (PSA) and prostate volume (PV). Safety assessments included International Index of Erectile Function (IIEF) and adverse events. Patients were evaluated at 3 months, 1 year and yearly thereafter. RESULTS Mean age of the group was 58.7 ± 6.7 years. Maintenance of therapy at 5 years was 57.4% and 42.5% for the finasteride and dutasteride groups respectively. Changes in IPSS, Qmax, PVR, PV and PSA were similar for both groups at 5 years. The incidence of erectile dysfunction, ejaculatory dysfunction and decreased libido resulting in discontinuation from therapy was significantly (p < 0.01) higher in the dutasteride (5.1%, 2.4%, 2.7% respectively) compared with the finasteride (2.1%, 1.8%, 1.4% respectively) group. In addition, the incidence of self-reported breast tenderness and/or enlargement was significantly (p < 0.01) greater in the dutasteride (3.5%) compared with the finasteride (1.2%) group. CONCLUSIONS In this retrospective analysis of data from consecutive patients treated at a single clinic, both finasteride and dutasteride were effective therapies for the management of lower urinary tract symptoms. However, dutasteride resulted in significantly more sexual side effects and breast complications than finasteride.

Abstract
PURPOSE We examined the effect of 5α-reductase inhibitor therapy on prostate cancer detection in men with persistently increased or fluctuating prostate specific antigen and prior negative prostate cancer biopsy. MATERIALS AND METHODS A total of 276 men with prostate specific antigen greater than 4 ng/ml (208) or a prostate specific antigen velocity change of 0.75 ng/ml (68) and a normal digital rectal examination who had previously undergone biopsy a minimum of 2 times with prostate cancer not detected were given 5 mg finasteride (154) or dutasteride (122) daily. In phase 1, 97 patients had prostate specific antigen measured at 6 and 12 months with repeat transrectal ultrasonography and biopsy (12 cores) performed at 1 year. In phase 2, 179 patients underwent biopsy triggered by a change in nadir prostate specific antigen of more than 0.4 ng/ml. RESULTS In phase 1 at 1 year prostate specific antigen had decreased by 2.4 ng/ml (-46.7%), and prostate volume had decreased 7.1 ml (-17.9%). Prostate cancer was detected in 27 of 97 (27.8%) patients and the mean minimum prostate specific antigen velocity from a nadir of 0.4 ng/ml was 0.6 ng/ml. In phase 2, 48 of 179 (26.8%) men underwent repeat biopsy at a mean of 14.6 months. Of these 48 men 26 (54.1%) were found to have prostate cancer. Of the 26 men in whom prostate cancer was detected 20 (76.9%) were found to have Gleason score 7 or greater disease. CONCLUSIONS The magnitude of change in serum prostate specific antigen after 5α-reductase inhibitor therapy may be useful in diagnosing prostate cancer in patients with persistently increased or fluctuating prostate specific antigen and prior negative prostate biopsy.

Abstract
Traditionally, the gold standard for treatment of BPH has been the electrocautery-based TransUrethral Resection of the Prostate (TURP). However, the number of laser techniques being performed is rapidly increasing. Potential advantages of laser therapy over traditional TURP include decreased morbidity and shorter hospital stay. There are several techniques for laser prostatectomy that continue to evolve. The main competing techniques are currently the Holmium Laser Enucleation of the Prostate (HoLEP) and the 80W 532nm laser prostatectomy. The HoLEP, using the Holmium:YAG laser, has been shown to have clinical results similar to TURP and is suitable for patients on anticoagulation as well as those with large prostates. Disadvantages of this technique are the high learning curve and requirement of a morcellator. When used to treat BPH, studies have demonstrated that, like the HoLEP, the 80W KTP laser is safe and effective in patients with large prostates and in those taking oral anticoagulation. Several studies have compared these two techniques to TURP. Frequently reported advantages of the HoLEP over the 80W laser prostatectomy are the availability after the procedure of a pathology specimen and ability to remove a higher percentage of prostate tissue during resection. However, the transurethral laser enucleation of the prostate addresses these concerns and has shown to have durable outcomes at 2-year follow-up. Two new laser systems and techniques, the thulium laser and the 980nm laser, have emerged recently. However, clinical data from these procedures are in their infancy and large long-term studies are required.

Abstract
Lower urinary tract symptoms (LUTS), overactive bladder, (OAB), and benign prostatic hyperplasia (BPH) are very commonly experienced in men. The mainstay of pharmacotherapy for OAB is the antimuscarinic class of drugs. There has been reluctance to prescribe these agents to men with BPH due to the risk of precipitating urinary retention. Several trials have supported the efficacy and safety of antimuscarinics in treating men with LUTS, alone, or in combination with α-blocker therapy. The combination of 5-α-reductase inhibitors with antimuscarinic agents or surgery are other effective treatments for men with BPH and OAB.

Abstract
Xanthogranulomatous inflammation is a benign condition characterized by the presence of multinucleated giant cells, chronic inflammatory cells and lipid-laden macrophages, known as xanthoma cells. Only 22 cases of xanthogranulomatous cystitis (XGC) have been reported in the Japanese and English literature. In this report, we describe the twenty-third case of XGC and the third case associated with inflammatory bowel disease (IBD). A 50-year-old woman with quiescent Crohn's disease was incidentally found to have a bladder mass on ultrasound. The lesion was resected through a transurethral approach. Pathology demonstrated XGC. At 3 months post-resection, there was no evidence of recurrence adjacent to the previous resection scar.

Abstract
Treatment of Lower Urinary Tract Symptoms (LUTS) from Benign Prostatic Hyperplasia (BPH) has evolved from surgical therapy to medical monotherapy to combination therapy. First-line medical therapy for men with LUTS remains agents that decrease outlet resistance: alpha-adrenergic antagonists and 5alpha-reductase inhibitors. Alpha-adrenergic agents decrease smooth muscle tone in the prostate and bladder neck. The mechanism of action of 5alpha-reductase inhibitors is reduction in prostate volume. First-line therapy for OAB symptoms are antimuscarinic agents. There has been reluctance to prescribe these agents to men with BPH due to the perceived risk of precipitating urinary retention. Alpha-adrenergic antagonists, 5alpha-reductase inhibitors, and antimuscarinic agents have all been shown to be safe and effective when administered to men with BPH and LUTS. The combination of 5alpha-reductase inhibitors with alpha-adrenergic antagonists is effective in men with LUTS secondary to BPH. The combination of alpha-adrenergic antagonists plus antimuscarinic agents and the combination of 5alpha-reductase inhibitors with antimuscarinic agents are safe and effective in patients with LUTS, evidence of BPH, and OAB symptoms. At present only combination therapy with 5alpha-reductase inhibitors with alpha-adrenergic antagonists is recommended in clinical practice guidelines. MTOPS and ComBAT have demonstrated superiority of combination therapy over monotherapy in preventing disease progression. Further studies are required to elucidate which specific patient population benefits most from particular combination therapies.
