New and Emerging Technologies in Treatment of Lower Urinary Tract Symptoms From Benign Prostatic Hyperplasia

Lower urinary tract symptoms (LUTS) from bladder outlet obstruction from benign prostatic hyperplasia (BPH) occur in a large percentage of urologic patients. Treatment of this condition with medical and surgical therapy provides symptom relief but has serious adverse effects and causes sexual dysfunction. New technologies to treat BPH-associated LUTS aim to effectively treat urinary symptoms and minimize side effects and sexual dysfunction.

To review the efficacy of new and emerging therapies for treatment of LUTS from BPH.

A literature search was performed to identify therapies for LUTS from BPH with early outcomes data within the past 5 years.

Improvement in International Prostate Symptom Score (IPSS) and effect on sexual functions such as erectile and ejaculatory functions as measured on the International Index of Erectile Function and the Male Sexual Health Questionnaire.

Technologies introduced within the past 5 years include techniques using intraprostatic injectables, mechanical devices, and prostatic tissue ablation. Most technologies remain in the development phase and have only phase I and II studies available that show promising alleviation of urinary symptoms. Injectables have not typically surpassed placebo or sham effects, although special cohorts could be exceptions. Thus far, convective water vapor ablation therapy and prostatic urethral lift have shown the most promise, with short- and medium-term data available on phase III studies demonstrating significant improvement in IPSS with minimal impact on sexual function. Many of these technologies are limited in their potential treatment population by prostate size and conformation, whereas other therapies might be more generalizable.

Many new technologies aim to treat LUTS from BPH and minimize sexual side effects. Most therapies remain experimental, although prostatic urethral lift and water vapor ablation therapy have been brought to market and show promise. Long-term durability of symptom relief remains to be demonstrated. Gupta NK, Gange SN, McVary KT.
