Pulsed-wave vs Continuous-wave Thulium Fiber Laser Enucleation of the Prostate (ThuFLEP): A Comparison of Perioperative Outcomes.

OBJECTIVE: To compare intra and early postoperative outcomes between pulsed-wave and continuous-wave Thulium Fiber Laser Enucleation of the Prostate (PW-ThuFLEP vs CW-ThuFLEP) for the treatment of benign prostatic hyperplasia. METHODS: 238 patients with lower urinary tract symptoms due to benign prostatic hyperplasia underwent PW-ThuFLEP (118 patients) vs CW-ThuFLEP (120 patients). Preoperative prostate volume, adenoma volume, prostate-specific antigen (PSA), and hemoglobin values were recorded. International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), post-void residual volume, and International Index of Erectile Function-5 score (IIEF-5) were assessed. Operative time, enucleation time, enucleation efficiency, catheterization time, irrigation volume, hospital stay, hemoglobin drop, and postoperative complications were recorded. Micturition improvements and sexual outcomes were evaluated 3months after surgery. RESULTS: CW-ThuFLEP showed shorter operative time (61.5 vs 67.4 minutes, P = .04). Enucleation time (50.2 vs 53.3 minutes, P = .12), enucleation efficiency (0.8 vs 0.7 g/min, P = .38), catheterization time (2.2 vs 2.1days, P = .29), irrigation volume (32.9 vs 32.8L, P = .71), hospital stay (2.8 vs 2.6days, P = .29) and hemoglobin drop (0.38 vs 0.39 g/dL, P = .53) were comparable. No significant difference in complication rate was observed. At 3-month follow-up, the procedures did not show any significant difference in IPSS, Qmax, post-void residual volume, IIEF-5, and PSA value. CONCLUSION: PW-ThuFLEP and CW-ThuFLEP both relieve lower urinary tract symptoms equally, with high efficacy and safety. Operative time was significantly shorter with CW-ThuFLEP, but with a small difference with low clinical impact. Enucleation time, enucleation efficiency, catheterization time, irrigation volume, hospital stay, hemoglobin and PSA drop, complication rate, and sexual outcomes showed no differences.

Role of Complementary Medicine (Music, Acupuncture, Acupressure, TENS and Audio-Visual Distraction) in Shockwave Lithotripsy (SWL): A Systematic Review From EAU Sections of Urolithiasis (EULIS) and Uro-Technology (ESUT).

We performed a systematic review to look at the role of alternative or complementary medicine such as music, acupressure, acupuncture, transcutaneous electrical nerve stimulation (TENS) and audiovisual distractions to decrease analgesia requirement and alleviate anxiety during SWL. Twenty-three papers(2439 participants) were included: Music (n = 1056.6%), Acupuncture (n = 517.7%), Acupressure (n = 13.8%), TENS (n = 617.2%), and audiovisual distraction (n = 14.6%). Most of the studies showed that complementary therapy, lowered pain, and anxiety with higher patient satisfaction and willingness to undergo the procedure. With its feasibility and convenience, urological guidelines need to endorse it, and more should be done to promote its use in outpatient urological procedures.

Aquablation of the prostate: single-center results of a non-selected, consecutive patient cohort.

PURPOSE: Aquablation of the prostate using the AquaBeam™ system promises equivalent functional outcomes, reduced learning curve, and improved sexual function compared to transurethral prostate resection as shown in prospective randomized trials. This prospective cohort study aims to evaluate if published results can be transferred into the clinical routine in a non-selected patient collective. METHODS: This study includes all patients treated between September 2017 and June 2018 with Aquablation of the prostate. Patients have been evaluated prospectively for the perioperative course and early follow-up. Besides voiding parameter and symptom score, TRUS-volume change, ejaculatory function, and adverse events have been recorded. RESULTS: 118 consecutive patients have been treated in the given time. Aquablation could be carried out successfully in all patients. IPSS, QoL, Qmax, and PVR improved significantly after the procedure and continued to improve during 3-month follow-up. Mean OR time was 20 min, TRUS volume decreased by 65%, and 73% of the patients retained antegrade ejaculation. Thirteen adverse events (> Clavien-Dindo I) occurred in 10 patients. CONCLUSION: The surgical ablation of the prostate using Aquablation achieved significant and immediate improvement of functional voiding parameters Qmax and PVR as well as symptomatic improvement of IPSS and QoL. Aquablation seems to be safe and effective with a low perioperative complication profile even in a non-selected group of patients.

Do prostatic stents solve the problem of retention after transurethral microwave thermotherapy?

Temporary nonmetallic stents offer an alternative to an indwelling catheter for the management of voiding problems after heat-based therapies for benign prostatic hyperplasia. Patient comfort is improved, and they are able to void immediately after the procedure. Unlike a catheter, stents function on the principle of active drainage. Thus, a functioning detrusor muscle is imperative for stent success. Single-center clinical trials have reported encouraging results; however, predictable success criteria are yet to be established. Multicenter trial data are awaited.

Transurethral microwave thermotherapy for the treatment of prostatitis.

The lethal action of microwaves on various microorganisms is well established and has been exploited in various clinical settings. Transurethral microwave thermotherapy (TUMT) has become a recognized modality for the treatment of prostatic diseases. Recently, it has been applied for the treatment of patients with nonbacterial prostatitis unresponsive to traditional therapeutic schemes. We review the current literature and present our recent encouraging experience with the in vitro bactericidal effect of microwaves on bacteria considered possible etiologic agents of prostatitis. Thus, we may consider the application of TUMT in patients with chronic bacterial prostatitis.

Transrectal microwave hyperthermia for patients with benign prostatic hyperplasia.

BACKGROUND: A randomized study evaluated the efficacy of treatment with transrectal microwave hyperthermia (TMH) treatment in patients with benign prostatic hyperplasia (BPH). METHODS: Eighty BPH patients received TMH therapy and 20 patients were given a sham treatment. TMH was achieved using a prostathermer which includes a microwave transrectal heat generator, a cooling system and a transurethral sensor probe. Patients that received TMH had 5 to 6 sessions of 1 hour each where the prostate was heated to 42 degrees C to 43.5 degrees C. The sham treatment consisted of a single session where the temperature was maintained at 37 degrees C. All patients were evaluated at 3 and 12 months after treatment. RESULTS: There was an improvement of subjective obstructive symptoms in 54 patients (75%) after TMH. An evaluation of urodynamic parameters revealed an increase in the maximum flow rate and a decrease of the detrusor opening pressure as well as the detrusor pressure at maximum flow in patients treated with TMH. A significant improvement in the amount of residual urine was seen in all TMH-treated patients (P < 0.0001). CONCLUSION: Although TMH cannot be considered a superior alternative to open surgical or transurethral excision of the prostate, it is a valid option for patients who have indwelling urethral catheters and for those at high surgical risk.

Urodynamic indices change as a result of transrectal microwave thermotherapy (TMT) in benign prostatic hyperplasia (BPH).

Fifty-three patients with BPH have been evaluated and treated with TMT with a follow-up at 7 months. The prostate was heated transrectally to 42-43 degrees C and the treatment consisted of 5 to 6 sessions. The duration of each session was 60 minutes. The urodynamic parameters studied revealed an increase of the maximum flow rate and a decrease of the detrusor opening pressure as well as the detrusor pressure at maximum flow. A significant improvement in the amount of residual urine was seen in all patients. Based on the above, we propose TMT as a viable alternative to open surgical or transurethral removal of the prostate. Furthermore, TMT may serve as a preferred treatment option in patients with indwelling urethral catheters and highly increased surgical risk.
