Can the Penile Cuff Test Predict the Outcome of Holmium Laser Enucleation of the Prostate for Benign Prostatic Obstruction?

Objective: To determine whether the penile cuff test can predict surgical outcomes prior to Holmium laser enucleation of the prostate for benign prostatic obstruction.

Methods: Men scheduled to undergo Holmium laser enucleation of the prostate were enrolled in this study, and all patients underwent the penile cuff test prior to and 3 months after surgery. Patients were categorized as obstructed, nonobstructed, or uncertain by nomogram. Surgical outcomes were assessed by evaluating changes in their international prostate symptom score, quality of life index, and maximum flow rate preoperatively and 3 months postoperatively. The proportion of patients with good outcomes was compared among nomogram-classified groups, and postoperative changes in position on the nomogram were assessed.

Results: A total of 125 patients were analyzed. After surgery, the overall treatment efficacy and symptomatic treatment efficacy were not different between obstructed and nonobstructed patients. However, the maximum flow rate and quality of life score were significantly higher after surgery in obstructed patients compared to nonobstructed patients. After surgery, 75.7% of patients with obstruction and 63.6% of patients categorized as uncertain for obstruction transitioned to the nonobstructed group, while 77.3% of nonobstructed patients remained in the nonobstructed group.

Conclusion: The penile cuff test can be used in patients with bladder outlet obstruction to predict good functional outcome and improved quality of life following treatment with Holmium laser enucleation. After Holmium laser enucleation of the prostate, the majority of patients were classified as nonobstructed.
