Background
Sexual dysfunction is a common side effect of medical therapy for benign prostatic hyperplasia (BPH), whereas prostatic urethral lift (PUL) offers safe and effective relief of lower urinary tract symptoms while preserving sexual function.
Objective
To compare the long-term impact on sexual health of PUL or daily medical therapy of doxazosin or finasteride alone or in combination in BPH patients.
Design, setting, and participants
This was a comparative analysis of sexual function outcomes from PUL studies (L.I.F.T. [n = 107], Crossover [n = 42], and MedLift [n = 39]) and the Medical Therapy of Prostatic Symptoms (MTOPS) trial. The men included were sexually active with International Prostate Symptom Score ≥13, Qmax ≤12 ml/s, and prostate volume 30–80 cm3. MTOPS subjects completed the Brief Male Sexual Function Inventory, while PUL subjects completed the International Index of Erectile Function and the Male Sexual Health Questionnaire for Ejaculatory Function.
Outcome measurements and statistical analysis
Mean percentage changes from baseline in erectile, ejaculatory, and sexual satisfaction domains were compared at 12, 24, 36, and 48 mo.
Results and limitations
PUL significantly improved erectile function through 24 mo, and ejaculatory function and sexual satisfaction across all time points. Medical therapy did not improve sexual function at any time point. Finasteride significantly decreased erectile function at 48 mo, and combined therapy significantly reduced ejaculatory function at 12 and 24 mo. Comparatively, PUL was superior to finasteride in preserving erectile function at 24 and 48 mo, and superior to doxazosin and combined therapy at 12 mo. PUL outperformed all three medical therapies at all time points in improving ejaculatory function and sexual satisfaction. Limitations include the use of distinct patient-reported questionnaires and narrowed data on comorbidities that influence male sexual function.
Conclusions
Indirect comparison reveals that PUL is superior to BPH medical therapy in preserving erectile and ejaculatory function and sexual satisfaction.
