In this study we aimed to determine the location of the neuronal nitric oxide (nNOS) in the human prostate and compare the results with urinary retention and nonretention patients. nNOS immunohistochemistry were performed on histopatologically proven benign hyperplastic tissue. Patients were divided into two groups as a patients with urinary retention and non retention. nNOS staining was negative in all of patients with urinary retention, however, it was negative in 12 of 20 patients and weak positive in 8 in noncathetherized patients. Another finding was the negative staining in areas which bazal cell proliferation were seen, however strong staining were observed in the areas of containing atrophic glands. The pattern of glandular nNOS was relatively homogeneous in all specimens.
As a result, in patients with urinary retention, nNOS expression is reduced compared to that in noncathetherised patients. This study also shows that nitrinergic innervation is reduced in patients with urinary retention. This result may be the cause or result of urinary retention in BPH patients. Further studies are needed to confirm the role of nNOS in the pathophysiology of BPH.Keywords: nitric oxide, benign prostatic hyperplasia,
