“…As was shown in previous studies, 11,17 our trial also demonstrated that there were no significant differences in total operating time or lasering time for these laser techniques. On the other hand, the amounts of total applied laser energy were significantly different between the techniques, with PVP requiring the smallest amount.…”

“…There have been few reports published which compare different laser techniques for BPH. A recently published meta‐analysis conducted by Zhou et al 11 to evaluate efficacy and safety of HPS‐PVP (120 W) and DVP using a side‐firing noncontact fiber (maximum output power 200 W) or Twister TM Large Fiber (Ceram Optec) with a contact mode (300 W) suggested that HPS‐PVP showed a significant improvement in total IPSS and QOL Index at 12 months after surgery, with a lower incidence of postoperative adverse events compared to DVP. However, during our trial, there were no significant differences in functional outcomes or postoperative complications at any follow‐up interval between the three groups.…”

A prospective, single‐center, randomized clinical trial to evaluate the efficacy of three types of laser vaporization surgeries using a 180‐W GreenLight XPS laser, a 300‐W diode laser, and a 200‐W thulium laser for the treatment of benign prostatic hyperplasia

Objectives This study aimed to compare the safety and efficacy of three different laser prostate vaporization surgeries, which were photoselective vaporization of the prostate (PVP), diode laser vaporization (DVP), and thulium laser vaporization (ThuVAP), for the treatment of benign prostatic hyperplasia (BPH) in a randomized clinical trial. Methods A total of 71 consecutive patients with BPH were included; 23 patients were treated with PVP, 23 with DVP, and 25 with ThuVAP. Patients were evaluated with disease‐related symptomatic questionnaires, Quality of Life (QOL) Index, and maximum urinary flow rate (Qmax) for 12 months. Patients were monitored to record operation/vaporization time, 24‐hour hemoglobin/sodium drop, length of catheterization/hospitalization, and perioperative/postoperative complications. Results In all three groups, patients showed significant and comparable improvements in symptom scores, QOL Index, and Qmax during the 12‐month follow‐up period. The mean operation/vaporization time was equivalent across all three groups at 69/23 (PVP), 81/34 (DVP), and 76/32 minutes (ThuVAP), while the applied laser energy was lower for PVP at 157 kJ compared to the other two techniques (DVP at 358 kJ, ThuVAP at 240 kJ). The mean vaporization rates per unit energy were significantly different between the three groups (PVP 0.16, DVP 0.09, and ThuVAP 0.09 mL/kJ). There were no significant differences in the main safety profiles between the three groups. Conclusions Our study demonstrated that these three types of laser surgeries are similar in terms of complications and outcomes, with excellent hemostasis and high patient satisfaction. It was suggested that sufficient tissue vaporization could be achieved using less energy through PVP surgery.

“…The diode laser exhibits a coagulation rim measuring 0.5 mm (with a range of 0.2-1 mm) when applied to prostate tissue, and it does not induce any hemorrhage. 18 The absorption of energy primarily occurs at the surface of prostatic tissue, resulting in enhanced ablative and hemostatic qualities. This effect remains significant even in patients who are undergoing oral anticoagulant therapy.…”

“…In the context of the 980 nm diode laser, the rate of vaporization remains unaffected by the specific tissue type, whether it is mucosa or fibromuscular stroma. 18,19 This distinguishes the diode laser from other laser systems. In addition, the diode laser possesses the notable benefit of reduced energy consumption and obviates the need for high-voltage connections, hence enhancing the portability of the laser generator.…”

Objective: To determine the outcome of laser vaporization of prostate using diode at 980/1470 nm for the treatment of BPH among high risk patients. Study Design: Longitudinal Observational Study. Setting: Shalamar Hospital, Lahore. Period: June 2009 till June 2022. Material & Methods: Total of 500 patients with associated co-morbid illnesses and benign prostate hyperplasia not responding to medical therapy, failed trial without catheter, chronic urinary retention, refusal for TURP were assessed for eligibility to enter the study. Inclusion criteria were patients with refractory urinary retention, chronic urinary retention, failure of previous medical treatment. Exclusion criteria were patients with neurogenic bladder, carcinoma of prostate, carcinoma of bladder, abnormal digital rectal examination, known neurological disorder or history of spinal cord injury also were excluded from study. Results: The patients’ mean age ‎was 68.57 ± 7.98 years, Baseline mean maximum urinary flow rate was 5.57±‎2.44 mL/s, post void residual was 130.91‎±‎24.18 mL, and international prostate symptom score was 26.09 ‎±‎2.40 at preoperative. At 3 months follow-up, Qmax was 23.31±‎8.0, PVR was 22.43±5.21 and IPSS was 7.27‎±‎1.42. On the other hand, mean Qmax was 25.83‎±‎6.84 mL/s, PVR was 18.38‎±‎4.53 mL, and IPSS was 5.29 ±‎0.61 at 6 months follow-up. Conclusion:Treatment of BPH by 980/1470 nm diode laser have effective and safe clinical outcome for high risk patients as we found significant improvements in Qmax, IPSS, and PVR at 3 months and 6 months follow up.

Purpose of reviewIn this narrative review, we will focus on a novel thulium fiber laser's physical properties in terms of its clinical applicability.Recent findings TFL has successfully moved forward from the preclinical trials into clinical practice and now is being widely used in clinics around the world. The available data suggest that the device effectively operates in soft tissues -benign prostate hyperplasia (BPH) and bladder tumors, as well as in lithotripsy. Also, the first promising results were obtained from laparoscopic surgery showing its possible applicability in the management of renal cell carcinoma. The constructional changes in fiber laser's design, lead to alteration of laser-tissue interactions, which resulted in clinical advantages of the device. Yet, the exact mechanism often is considered complex for understanding. With this work, we are aiming to build a bridge between biophysics and clinical practice and give a simple explanation of how the devices is working and why the knowledge of it is important for a clinician.
