BPH

(page 592,

Pathophysiology: A 2-in-1 Reference for Nurses

)

"BPH begins with nonmalignant changes in periurethral glandular tissue. The growth of fibroadenomatous nodules (masses of fibrous glandular tissue) progresses to compress the remaining normal gland (nodular hyperplasia). The hyperplastic tissue is mostly glandular, with some fibrous stroma and smooth muscle. As the prostate enlarges, it may extend into the bladder and obstruct urinary outflow by compressing or distorting the prostatic urethra. There are periodic increases in sympathetic stimulation of the smooth muscle of the prostatic urethra and bladder neck. Progressive bladder distension may also cause a pouch to form in the bladder that retains urine when the rest of the bladder empties. The retained urine may lead to calculus formation or cystitis."

Erectile Dysfunction

(page 599,

Pathophysiology: A 2-in-1 Reference for Nurses

)

"Neurologic dysfunction results in lack of the autonomic signal and, in combination with vascular disease, interferes with arteriolar dilation. The blood is shunted around the sacs of the corpus cavernosum into medium-sized veins, which prevents the sacs from filling completely. Also, perfusion of the corpus cavernosum is initially compromised because of partial obstruction of small arteries, leading to loss of erection before ejaculation.

Psychogenic causes may exacerbate emotional problems in a circular pattern; anxiety causes fear of erectile dysfunction, which causes further emotional problems."
