Brief Summary

Benign prostatic hyperplasia (BPH), the non-malignant enlargement of the prostate gland, places pressure on the urethra and causes urination difficulties and bladder problems. Lower Urinary Tract Symptoms (LUTS) secondary to BPH is a common condition in aging men, with an overall prevalence of more than 50% in those older than 50 years of age. Men with LUTS often experience sexual dysfunction including ejaculatory loss, painful ejaculation, and erectile dysfunction, which among other complications can also lead to a decreased quality of life. Holmium laser enucleation of the prostate (HoLEP), first reported by Fraundorfer et al in 1998, is a more recent step in the evolution of holmium laser prostatectomy. HOLEP offers patients the alternative of being treated endoscopically with minimal blood loss, short catheterization time, and decreased hospital stay. One noted drawback to HoLEP, and the primary reason why it has yet to become the new standard for treatment of symptomatic BPH, is the complexity of this procedure, with a prolonged learning curve. Modifications to the procedure have thus been explored in order to address this limitation. The "Top-Down" HoLEP technique is a novel technique which offers potential benefits to the Traditional HoLEP procedure, including decreased complexity, a reduced learning curve, with anticipated improved continence. This study will compare the operating time between the Top-Down Holmium Laser Enucleation of the prostate (HoLEP) and the Traditional HoLEP for the treatment of patients with symptomatic bladder outlet obstruction due to BPH in Northwestern Ontario.

Traditional HoLEP

ACTIVE COMPARATOR

Holmium laser enucleation of the prostate (HoLEP), first reported by Fraundorfer et al in 1998, is a more recent step in the evolution of holmium laser prostatectomy. HoLEP is a safe and effective procedure which has demonstrated comparable results to Transurethral Resection of the Prostate (TURP) and open prostatectomy for patients with symptomatic enlarged prostate, with low morbidity and short hospital stay \[4\]. The improvement in outcome parameters is durable, and the late complications and reoperation rates reported are very low \[5\]. HoLEP is equally suitable for small, medium and larger prostate glands, with clinical outcomes that are independent of prostate size, unlike TURP. HOLEP offers patients the alterative of being treated endoscopically with minimal blood loss, short catheterization time, and decreased hospital stay \[6\].

Procedure: Traditional HoLEP

Top-Down HoLEP

ACTIVE COMPARATOR

The "Top-Down" HoLEP technique is a novel technique which offers potential benefits to the Traditional HoLEP procedure, including decreased complexity, a reduced learning curve, with anticipated improved continence \[8\]. A variation of this method is also being explored in Japan (termed the "en-bloc technique with anteroposterior dissection HoLEP") \[9\]. The main difference between the Top-Down and Traditional approach is that the direction of lateral dissection begins from upwards to downwards. This could help in avoiding the overtraction of the mucosal strip overlying the posterior urethral sphincter, which theoretically leads to a decrease in the incidence of postoperative stress incontinence. Moreover, using the Top-Down approach should lead to a decrease in the incidence of lost enucleation planes, which results in decreasing the intraoperative time and decreasing the number of cases required to master the HoLEP technique.

We have no plan to share individual data with any other researchers. We do plan to present our findings at various national and international conferences in the future... however all participant data will have been de-identified and grouped at that point.
