Bothersome lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) is a common problem, which impact patients' quality of life. It may lead to serious outcomes, including urinary tract infection, hematuria, bladder stones, urinary retention, hydronephrosis, and rarely renal insufficiency.
Introduction of the Holmium laser enucleation of the prostate (HoLEP) represented a turning point in minimally invasive laser therapy for BPH as it achieves size-independent prostatic cavities similar to simple open prostatectomy with significantly lower perioperative morbidity.
Recently, Holmium Xpeeda side firing fibre was introduced and it stands apart from other available technologies as a combination of power and efficiency, which minimizes vaporization time. This technology seems to revolutionize utilization of the Holmium power and delivering more energy directly to the tissue, due to its capability of being in contact with the tissue.
To date, no outcomes of the new Xpeeda laser fiber have been reported in the literature, which is striving for trials comparing XPS 180W with other competitors such as Holmium vaporesection with the new fiber Xpeeda. Therefore, this study is planned to compare both procedures in improving bothersome LUTS secondary to BPH, and to evaluate safety and cost effectiveness.
Bothersome lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) is a common problem, which impact patients' quality of life. It may lead to serious outcomes, including urinary tract infection, hematuria, bladder stones, urinary retention, hydronephrosis, and rarely renal insufficiency. Symptoms of BPH are due to prostatic enlargement, increased smooth muscle tone from the bladder and prostate, and changes in bladder contractility leading to lower urinary tract obstruction, which may cause permanent kidney damage if left untreated.
Introduction of the Holmium laser enucleation of the prostate (HoLEP) represented a turning point in minimally invasive laser therapy for BPH as it achieves size-independent prostatic cavities similar to simple open prostatectomy with significantly lower perioperative morbidity. It has successfully passed the steps of validation through a growing number of well-designed randomized controlled studies to have a high level of evidence for safety and efficacy. The pulsed nature of holmium laser allows the plane of enucleation to be easier to develop and follow and gives superior visibility than the electro-cauterization with less charring of tissue.
HoLEP proved itself as the only endoscopic procedure with superior efficacy compared to the traditional transurethral resection of the prostate (TURP). Furthermore, it is not only safe, effective, size-independent and durable even in patients with coagulopathy, but also more cost-effective than TURP. Meta-analyses have confirmed how well established HoLEP has now become, with a low long-term retreatment rate and the more pronounced improvement in prostate symptoms score and flow rate than after TURP.
Recently, Holmium Xpeeda side firing fibre was introduced and it stands apart from other available technologies as a combination of power and efficiency, which minimizes vaporization time. This technology seems to revolutionize utilization of the Holmium power and delivering more energy directly to the tissue, due to its capability of being in contact with the tissue. Moreover, hemostasis would be improved by the pulse reshaping technology with a wider pulse width, activated by a dedicated footswitch. Therefore, the Lumenis Pulse™ 100W will make prostate vaporesection procedures more precise, faster and efficient, with excellent hemostasis. Consequently, bleeding is minimal, tissue is easier to remove and patients can have their catheter removed faster.
On the other hand, Greenlight 532nm laser photoselective vaporization of the prostate (PVP) is an appealing treatment modality with hemoglobin as tissue target chromophore and relatively short learning curve. The introduction of the Xcelerated Performance System (XPS) 180W in 2010 with the MoXy fibres represents the highest-powered system currently in use for this type of laser. It encourages the adoption of the enucleation principle, making it a real contender to HoLEP in treating large adenomas. Despite the fact that large prostates often require more energy and longer operative time, the XPS system has reduced the operative time and number of fibres required in these situations.
Elmansy et al reported that Greenlight vaporization and Holmium laser ablation of the prostate (HoLAP) are effective surgical treatments for BPH in small to medium prostates. The two techniques have similar functional outcomes and complication rates. Subjective and objective voiding parameters showed significant improvement lasting for up to 3 years, confirming the long lasting, durable effects of each technique.
To date, no outcomes of the new Xpeeda laser fiber have been reported in the literature, which is striving for trials comparing XPS 180W with other competitors such as Holmium vaporesection with the new fiber Xpeeda. Therefore, this study is planned to compare both procedures in improving bothersome LUTS secondary to BPH, and to evaluate safety and cost effectiveness.

| Prostate specific antigen (PSA) | The PSA test Measures the level of PSA (protein produced by normal, as well as malignant, cells of the prostate gland) in a blood sample. The normal PSA value is usually stated to be less than 4.0 μg/L. However, because of the fact that benign enlargement of the prostate gland tends to occur as men get older, an age-adjusted scale has been developed: 0-2.5 μg/L = Normal for a man 40-50 yrs; 2.5-3.5 μg/L = Normal for a man 50-60 yrs. For men aged 70 to 79, they suggested a normal serum PSA reference range of 0.0-6.5 ng/mL (0.0-6.5 μg/L). | Baseline |

An ultrasound probe is inserted into the rectum to check the prostate. The probe bounces sound waves off body tissues to make echoes that form a sonogram (computer picture) of the prostate. Sonogram at baseline will be compared to that at 3-months post-op and prostate size measured using online measuring tools. |

| International index of erectile function-5 (IIEF-5) | The 5-question International Index of Erectile Function (IIEF) Questionnaire is a validated, multidimensional, self-administered investigation that has been found useful in the clinical assessment of erectile dysfunction and treatment outcomes. Questions are scored from 1-5, with lower scores indicating increased levels of erectile dysfunction, while higher scores indicate higher erectile function. The possible scores for the IIEF-5 range from 5 to 25, and erectile dysfunction (ED) is classified into five categories based on the scores: severe (5-7), moderate (8-11), mild to moderate (12-16), mild (17-21), and no ED (22-25). | Surgery |
