Update in minimal invasive therapy in benign prostatic hyperplasia

Area of Science:

• Urology
• Minimally Invasive Surgery
• Benign Prostatic Hyperplasia (BPH) Management

Background:

• The past decade has seen the development of numerous minimally invasive treatment options for BPH.
• Traditional treatments like monopolar TURP have limitations, driving the search for alternatives.

Purpose of the Study:

• To review and compare various minimally invasive therapeutic modalities for BPH.
• To assess the clinical efficacy and long-term outcomes of emerging BPH treatments.

Main Methods:

• Review of clinical studies on bipolar transurethral resection of the prostate (TURP), TUR in saline (TURis), laser therapies, transurethral microwave thermotherapy (TUMT), high intensity focused ultrasound (HIFU), transurethral needle ablation (TUNA), hot water induced thermotherapy (WIT), prostatic stents, intraprostatic ethanol injections, and botulinum toxin A injections.
• Comparative analysis of techniques, outcomes, and suitability for different patient groups.

Main Results:

• Bipolar systems and photoselective vaporization may soon replace monopolar TURP.
• Holmium laser enucleation is a strong contender, though technically demanding.
• TUMT is a viable outpatient alternative, especially for high-risk patients.
• Long-term data for TUNA and HIFU is disappointing; WIT durability is questionable.
• Intraprostatic ethanol injections show promise but require larger studies.
• Botulinum toxin A injections offer a novel approach targeting both dynamic and static BPH components.

Conclusions:

• Several minimally invasive BPH treatments are emerging as potential replacements for traditional TURP.
• Some newer modalities show significant promise, particularly botulinum toxin A, but require further investigation.
• The choice of treatment depends on technique, efficacy, durability, and patient-specific factors.
