Benign prostatic hyperplasia (BPH) refers to the proliferation of smooth muscle and epithelial cells of the prostate gland. The enlarged gland has the potential to result in lower urinary tract symptoms (LUTS) secondary to either bladder outlet obstruction or increased muscle tone and resistance, or both.
For decades transurethral resection of the prostate (TURP) has been the gold standard for treatment of symptomatic BPH that is refractory to nonoperative management. This is a surgical intervention aimed to reduce the size of the prostate gland. However, over the past fifteen years, many alternative therapies have been introduced including laser enucleation of the prostate (LEP). LEP has numerous advantages including decreased blood loss and length of hospital stay as well as increased effectiveness and safety for large prostate gland sizes (>80g).
The purpose of this study is to compare the effectiveness of TURP to LEP using the ProTouch laser technology. While TURP has historically been the gold standard, LEP has become more widespread and is arguably a safer and more effective therapy for the patient. TURP is still widely performed because it is a traditional therapy with decades of data to support its efficacy, despite higher volume of blood loss and risk for TUR syndrome. In comparison, there is some data demonstrating that Holmium Laser Enucleation of the Prostate can have similar efficacy but may have longer operative times. The ProTouch laser is comparable to the Holmium laser but additionally provides improved hemostasis and tissue vaporization. There is little to no data comparing LEP with the ProTouch laser to TURP. This study will directly compare the efficacy of these two treatment methods by enrolling eligible subjects and comparing outcomes.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| ProTouch Laser Enucleation of Prostate | Active Comparator | The intervention for this group is that the patient will undergo endoscopic ProTouch Laser Enucleation of Prostate (LEP).The laser is used to enucleate large pieces of prostatic tissue which is followed by further ablation of the tissue so that no fragments are left in the bladder |
|
| Transurethral Resection of Prostate | Active Comparator | The intervention for this group that the patient will undergo endoscopic Transurethral Resection of Prostate (TURP) using bipolar cautery. The prostate is essentially shaved down using sequential cuts and cautery. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| ProTouch Laser Enucleation of Prostate (LEP) | Procedure | Laser enucleation of the prostate is a standard form of treatment for BPH used widely. The ProTouch laser is established to be safe and is newer than the holmium laser. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Urinary Flow Rate | Velocity (in cc/sec) of the urine flow | From time of randomization and ultimately at 24 months |
| Measure | Description | Time Frame |
|---|---|---|
| Quality of Life score | Survey to determine how satisfied the patient is with urination | From time of randomization and ultimately at 24 months |
