Abstract
Abstract
Purpose Prostatic artery embolization (PAE) has emerged as a minimally invasive alternative for patients with prostates >80 mL and has demonstrated lower morbidity rates. We sought to evaluate PAE at a single tertiary medical center. Methods A retrospective review of all patients who underwent PAE was completed. Demographic, clinicopathologic, procedure, and outcome data were collected to include international prostatic symptom score (IPSS) and quality of life (QoL) assessments. Results The pre-PAE mean prostate-specific antigen (PSA) was 8.4 ng/mL, mean prostate volume was 146.9 mL (9% >200 mL), and mean postvoid residual (PVR) was 208.2 mL (21.9% 200–300 mL). IPSS mean was 19.8 and QoL was “mostly dissatisfied.” Following PAE, mean PSA was reduced by 3.2 ng/mL (38.1%, p = 0.3014), the mean prostate volume reduction was 59.2 mL (40.3%, n = 19, p < 0.0001), and the average PVR reduction was 150.3 mL (72.2%, n = 27, p = 0.0002). Average IPSS score was also lower (11.9; 60.1%, n = 25, p < 0.0001) and QoL was reduced to “mostly satisfied” (p < 0.0001). Technical success was 100% with 24% minor morbidities. Conclusion PAE is a successful treatment for patients with BPH resulting in large prostates that are not good candidates for simple prostatectomy, providing optimal care with less operative and postoperative complications.

Photoselective Vaporization of the Prostate in the Management of Lower Urinary Tract Symptoms in Prostate Cancer Patients on Active Surveillance. Urology 2021; 156:225-230. [PMID: 33539897 DOI: 10.1016/j.urology.2021.01.040] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 01/20/2021] [Accepted: 01/21/2021] [Indexed: 10/22/2022]
Abstract
OBJECTIVE To demonstrate the safety and efficacy of photoselective vaporization of the prostate in alleviating refractory lower urinary tract symptoms in prostate cancer patients who are managed with active surveillance and to explore the association of this procedure with prostate specific antigen (PSA) levels and cancer progression rates. METHODS Between 2008-2018, active surveillance patients who had refractory symptoms and needed surgery were studied. Perioperative functional variables were collected and analyzed. Disease progression was defined as an upgrade or upstage on surveillance biopsies or multiparametric prostate magnetic resonance imaging. Mean postop scores were estimated using locally-weighted methods. The risk of progression was reported using Kaplan-Meier's method. RESULTS Seventy-one patients were included in the study. The median age was 68 years and the median surveillance time before surgery was 4 years. At 12 months, there were substantial improvements in the mean International Prostate Symptom Score (18-5.9), maximum flow rate (6.8-14 mL/s), postvoid residual (240-73mL), PSA (8.1-5.2 ng/mL), and prostate volume (85-57mL). At 30-days, only 2 patients with grade-III complications. Late consequences included tissue regrowth in 4 and urethral stricture (requiring a single dilation) in 3 patients. PSA levels decreased by 36% at 12 months postoperatively. With a median follow-up of 3.7 years, 7 men progressed and received radical treatment. At 3 years, the probability of remaining on surveillance was 93% (95% CI 87%- 100%). CONCLUSION Photoselective vaporization of the prostate offers substantial relief of symptoms in active surveillance patients with refractory symptoms, without adverse effects on disease progression rates.

Abstract
PURPOSE OF REVIEW Freedom from medication is a common goal for patients undergoing surgical treatment of benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS). Knowing medication discontinuation rates following various forms of transurethral prostatectomy may aid patient counseling and assessing the comparative effectiveness of different approaches. This review examined discontinuation rates of BPH/LUTS medications following transurethral prostatectomy. RECENT FINDINGS Rates of BPH/LUTS medication use after transurethral resection of the prostate varied from 15% to 55%, and discontinuation rates were 54-95% across medications and follow-up periods. For laser prostatectomy, approximately 18% of patients continued medications postoperatively and discontinuation rates ranged from 53% to 75%. Minimal data on holmium laser enucleation existed. For reference, medication discontinuation rates after transurethral needle ablation or microwave therapy were only 15-28%. No recommendations or best practices inform the use of medical therapy following BPH surgery. Rates of BPH/LUTS medication use following transurethral prostatectomy are considerable.

Impact of different color fiber sleeves on beam hazards of 532-nm laser and vaporization efficiency. Lasers Med Sci 2018; 34:801-805. [PMID: 30353478 DOI: 10.1007/s10103-018-2666-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2018] [Accepted: 10/16/2018] [Indexed: 10/28/2022]
Abstract
The 532-nm laser has become increasingly popular for the treatment of urologic diseases. However, laser beam will pose significant hazards for the health of surgeons. In order to reduce beam hazards during surgery, we compared the beam hazards of laser fiber with black sleeves to the traditional fiber with transparent sleeves, and the vaporization efficiency. A total of 18 porcine kidney specimens were vaporized in normal saline at a room temperature under 532-nm laser delivered through a 760-μm core diameter side firing fiber. Two groups were divided according to the color of fiber sleeves: the transparent and the black. Each group was then divided into another three subgroups by laser power: the 80 W group, the 120 W group, and the 160 W group. The beam hazard was evaluated by light intensity measured in a sector area at a distance of 0 m, 0.5 m, and 1 m from the irradiation center. The vaporization efficiency was measured by the vaporization groove depth under the working power of 80 W, 120 W, and 160 W with a working distance of 5 mm and irradiation time of 10 s. The light intensity measured in the black fiber sleeve group is significantly lower than that in the transparent one (P < 0.01), regardless of the measuring distance (0 m, 0.5 m, and 1.0 m) and laser power (80 W, 120 W, and 160 W). No statistical difference was found on the vaporization efficiency between the groups protected by fiber sleeves of different colors (transparent/black, p > 0.05). Compared to the traditional transparent fiber sleeves, more beam hazards will be reduced in the operative region with the protection of black fiber sleeves, especially those from the irradiation center. The vaporization efficiency is not affected by the color of fiber sleeves. Such findings may offer a completely new idea for the protection of surgeons in surgeries with 532-nm lasers.

Is loss of power output due to laser fiber degradation still an issue during prostate vaporization using the 180 W GreenLight XPS laser? World J Urol 2018; 37:181-187. [PMID: 29923013 DOI: 10.1007/s00345-018-2377-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2018] [Accepted: 06/12/2018] [Indexed: 02/03/2023] Open
Abstract
PURPOSE To investigate whether heat-induced fiber degradation and loss of power output, which occurred during GreenLight laser vaporization (LV) of the prostate using the first- and second-generation 80 and 120 W laser, are still an issue during LV using the upgraded third generation 180 W GreenLight XPS™ laser. METHODS Laser beam power output of 53 laser fibers was measured at baseline and after every 25 kJ of delivered energy during routine 180 W GreenLight XPS™ LV in 47 patients with prostatic bladder outflow obstruction. After the procedures, the fiber tips were microscopically examined. RESULTS The median applied energy per patient was 178 kJ [interquartile range (IQR): 106-247]. Loss of power output during the procedure was detectable in all fibers. After the application of 25, 150, and 250 kJ, the median power output decreased to 77% (IQR 59-87), 57% (IQR 32-71), and 51% (IQR 37-64) of the baseline value. Nine fibers (17%) remained on a relatively high power output level (> 80% of the initial output), while 13 fibers (25%) showed an end-of-procedure power output of less than 20%. Microscopy of the fiber tip revealed mild-to-moderate overall degradation and increasing degradation with higher energy delivered. CONCLUSION Despite changes in fiber design, heat-induced fiber damage and loss of power output remain an issue during 180 W GreenLight XPS™ LV. Whether modifications of the surgical technique can prevent impairment of fiber performance needs to be further evaluated.

Abstract
The surgical treatment of benign prostatic obstruction is changing over the time, thanks the increase evidence about the successful role of laser techniques in this surgery. We aimed to compare prostatic GreenLight photovaporization (PVP) to bipolar transurethral resection of the prostate (TURP) with regard to lower urinary tract symptoms (LUTS) improvement through the evaluation of BPH6. We enrolled 220 consecutive subjects affected by LUTS. We performed a propensity score matching using prostate volume, peak flow and International Prostate Symptoms Score (IPSS). A total of 110 (55 TURP and 55 PVP) were analyzed. We found after 1 year of follow-up that the rate of subjects resulting in greater BPH6 recovery in the PVP group vs TURP (45.6% vs 18.2%; P=0.001). The TURP treatment showed greater catheterization time (4.67 vs 1.25; P<0.01) while PVP showed greater recovery experience (82.4 vs 58.2; <0.01). Postoperative ejaculatory dysfunctions were observed in both groups, 58.8% in TURP and 34.5% in PVP group. The multivariate logistic regression analysis, adjusted for preoperative variables, showed that PVP was independently associated with BPH6 recovery end point (odds ratio=3.77; P<0.01). This study showed data in favor of PVP. Although IPSS and peak flow improvements were similar, PVP showed better clinical outcomes.

Abstract
PURPOSE OF REVIEW Surgical techniques are an integral part of the urologist's armamentarium for the treatment of benign prostatic obstruction. Currently, several techniques are available. The purpose of the current review is to analyse the long-term outcomes of currently available techniques. RECENT FINDINGS Open prostatectomy shows a low long-term reoperation rate. Available evidence suggests that bipolar transurethral resection of the prostate (TURP) is an attractive alternative to monopolar TURP as both techniques lead to a long-lasting and comparable efficacy. For patients with a larger prostate volume, bipolar enucleation of the prostate appears as safe and effective alternative to open prostatectomy. Holmium laser enucleation of the prostate appears as a durable alternative to TURP and open prostatectomy with comparable long-term results. For photoselective vaporization of the prostate, differently powered models are available. Currently, only long-term data with lower powered 80 W laser are available, reporting reoperation rates higher than those reported from other surgical techniques. On the thulium laser, currently only one study reported 5-year results and despite encouraging results further confirmation seems necessary. SUMMARY Various surgical methods have proven to be safe and effective for the treatment of benign prostate obstruction and stand the test of time. The choice of the technique depends on prostate size, risk factors of the patient as well as expertise of the surgeon.

Absorption of irrigation fluid during XPS™ GreenLight laser vaporization of the prostate: results from a prospective breath ethanol monitoring study. World J Urol 2016; 34:1261-7. [PMID: 26780733 DOI: 10.1007/s00345-016-1766-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2015] [Accepted: 01/06/2016] [Indexed: 12/13/2022] Open
Abstract
PURPOSE To assess whether and to what extent irrigation fluid absorption occurs during laser vaporization (LV) of the prostate using the 180 W XPS™ GreenLight laser. METHODS This prospective investigation was performed in a tertiary care center with a consecutive series of patients undergoing 180 W LV of the prostate. Intraoperative irrigation was performed with isotonic saline containing 1 % ethanol. The volume of irrigation fluid absorption was calculated from periodically performed breath ethanol measurements during LV. Additionally, intraoperative changes in biochemical and hematological blood parameters were assessed. RESULTS Positive breath ethanol tests were detectable in 22 of 54 patients. The median absorption volume in these patients was 950 ml (range 208-4579 ml). Ten patients absorbed more than 2000 ml. Absorbers had smaller prostates, more capsular perforations and injuries to venous sinuses, and more total energy was applied with higher output power. Five patients had transient symptoms potentially related to fluid absorption. A significant drop in hemoglobin, hematocrit, venous pH and bicarbonate and an increase in chloride were detectable in the absorber group. These changes were significantly different in the non-absorber group. CONCLUSIONS Absorption of irrigation fluid did occur in a relevant proportion of patients undergoing XPS™ GreenLight LV. High-volume absorption (≥2000 ml), which might be clinically relevant, was detectable in almost 20 % of all procedures. Absorption of saline irrigation fluid does not result in a classical TUR syndrome, but fluid and chloride overload can lead to serious complications, particularly in cardiovascular high-risk patients. Thus, patients with symptoms potentially related to fluid absorption should be monitored carefully.

Abstract
Introduction: This study investigated the clinical efficacy and safety of photoselective vaporization of the prostate (PVP) and simultaneous suprapubic cystostomy for benign prostatic hyperplasia (BPH) in patients with mild to severe detrusor underactivity (DU). Subjects and Methods: Seventy-eight patients with BPH were divided into 3 groups according to the severity of DU: mild DU group, moderate DU group and severe DU group. The preoperative and postoperative data, including the detrusor pressure at maximum flow (Pdetmax), bladder compliance, maximum urinary flow (Qmax), postvoid residual urine (PVR) values, International Prostate Symptom Score (IPSS) and quality of life (QoL) were evaluated. Results: The therapeutic effectiveness including cure and improvement in mild and moderate DU group was significantly higher than that of the severe group. Compared to the preoperative values, Pdetmax, bladder compliance, Qmax, PVR, IPSS and QoL scores at 12 months postoperatively had significantly improved. In addition, the above parameters at 12 months postoperatively in the mild or moderate DU group had significant difference compared to the severe DU group. Conclusion: PVP and simultaneous suprapubic cystostomy seem to be an appropriate treatment modality in BPH patients with mild and/or moderate DU as well as in patients with severe DU and slightly reduced bladder compliance.
