Abstract

Background

In older adults, bladder outlet obstruction (BOO) is prevalent, primarily due to benign prostatic hyperplasia (BPH). These patients' lower urinary tract symptoms can be treated surgically and with medical therapy. Compared to standard treatment with tamsulosin, Pentoxifylline, a phosphodiesterase inhibitor, could benefit patients with BOO due to its properties on microcirculatory blood flow and oxygenation of ischemic tissues. Hence, this trial intended to study the efficacy of Pentoxifylline combined with tamsulosin in treating BOO patients.

Materials and Methods

This randomized, double-blind clinical trial recruited 60 patients with BPH from a single center in 2022. Upon consent of patients meeting the eligibility criteria, they were randomly allocated to intervention (Pentoxifylline + tamsulosin) and control (placebo + tamsulosin) groups. The patients were evaluated for international prostate symptom score (IPSS), quality of life (QoL), maximum urinary flow rate (Q_max) by uroflowmetry, and post-void residual volume (PVR) by abdominal sonography at the onset of the study and after the 12th week.

Results

Patients who used the combination therapy had significantly better results of prostate symptoms and quality of life improvement (IPSS: −36.6%, QoL: −45.3%) compared to patients who received tamsulosin alone (IPSS: −21.2%, QoL: −27.7%) (p < .001). Also, this study shows that the improvement in maximum urinary flow rate and residual volume by combination therapy is significantly higher (Q_max: +42.5%, PVR: −42.6%) compared to monotherapy (Q_max: +25.1%, PVR: −26.1%) (p < .001).

Conclusion

When combined with tamsulosin, Pentoxifylline could significantly improve the lower urinary symptoms of BPH patients. It is well tolerated, and the treatment outcomes are better in patients who receive the combination of Pentoxifylline and tamsulosin than those who only receive tamsulosin.

在治疗良性前列腺增生引起的下尿路症状方面，坦索罗辛和喷托非利辛联合用药与单用坦索罗辛的比较：一项初步研究

在老年人中，膀胱出口梗阻（BOO）很普遍，主要是由于良性前列腺增生症（BPH）引起的。这些患者的下尿路症状可通过手术和药物治疗进行治疗。与使用坦索罗辛的标准治疗相比，磷酸二酯酶抑制剂本妥昔单抗（Pentoxifylline）可促进微循环血流和缺血组织的供氧，从而使BOO患者受益。因此，本试验旨在研究本妥昔单抗联合坦索罗辛治疗 BOO 患者的疗效。

期刊介绍： LUTS is designed for the timely communication of peer-reviewed studies which provides new clinical and basic science information to physicians and researchers in the field of neurourology, urodynamics and urogynecology. Contributions are reviewed and selected by a group of distinguished referees from around the world, some of whom constitute the journal''s Editorial Board. The journal covers both basic and clinical research on lower urinary tract dysfunctions (LUTD), such as overactive bladder (OAB), detrusor underactivity, benign prostatic hyperplasia (BPH), bladder outlet obstruction (BOO), urinary incontinence, pelvic organ prolapse (POP), painful bladder syndrome (PBS), as well as on other relevant conditions. Case reports are published only if new findings are provided. LUTS is an official journal of the Japanese Continence Society, the Korean Continence Society, and the Taiwanese Continence Society. Submission of papers from all countries are welcome. LUTS has been accepted into Science Citation Index Expanded (SCIE) with a 2011 Impact Factor.
