Research Interests

Our research introduces a new concept in the pathophysiology of lower urinary tract symptoms (LUTS) associated with erectile dysfunction (ED). The etiology of LUTS is poorly understood and the close association of LUTS and ED remains a clinical mystery. We have attempted to present a unifying concept, namely pelvic arterial insufficiency, as underlying the common clinical problems of LUTS and ED. We realize that each disorder has a complicated multifactorial etiology. However, in view of growing evidence from clinical and basic research, we are increasingly convinced that ischemia is an important etiological factor in ED-associated LUTS. Certainly, atherosclerosis can explain the marked association of these conditions with increased age and their association with vascular risk factors. In addition, the fact that the cavernosal, bladder and prostate smooth muscle alterations seen clinically can be reproduced in our experimental model of pelvic ischemia, lends further credence to our unifying hypothesis.

Our clinical studies have shown that human pelvic perfusion correlates with LUTS as well as erectile dysfunction. We also found that human bladder non-compliance correlates with decreased bladder blood flow. Our studies with experimental models have shown that pelvic ischemia exposes the bladder, prostate and penis to repeating cycles of oxidative stress as these organs undergo smooth muscle contraction and relaxation for regular physiologic activities. Oxidative stress under ischemic conditions triggers a cascade of molecular events involving oxidative stress-responsive genes, antioxidant defense mechanisms, growth factors, prostaglandins and leukotrienes leading to smooth muscle dysfunction, microvascular damage, neurodegeneration and fibrosis. Treatment with antioxidants appears to delay or prevent these changes.

Our current studies extend the previous findings to cellular and molecular mechanisms of oxidative and nitrosative injury and the roles of stress-responsive genes, antioxidant enzymatic system, S-nitrosylation, and mitochondrial and endoplasmic reticulum stress proteins in smooth muscle dysfunction, vasculopathy and neurodegeneration of the ischemic bladder, prostate and penile erectile tissue. Another goal is to develop newer prophylactic and therapeutic strategies against LUTS and ED using antioxidants.
