ABSTRACT
<p><b>OBJECTIVE</b>To study the influential factors leading to postoperative delirium in elderly patients with benign prostatic hyperplasia(BPH).</p><p><b>METHODS</b>For 198 elderly postoperative BPH patients in our hospital, the clinical parameters including age, hypoxemia, postoperative pain, and sleep reduction were investigated, and the data were processed by chi2 test.</p><p><b>RESULTS</b>Of the total number of patients, 13 (6.5%) experienced postoperation delirium. Many factors were significantly correlated with the problem in these elderly BPH patients, such as advanced age (> or =70), postoperative pain and sleep reduction (P < 0.05).</p><p><b>CONCLUSION</b>Advanced age, postoperative pain and sleep problem were important factors for delirium, and therefore postoperative analgesia and good sleep may help to prevent postoperative delirium.</p>

<p><b>OBJECTIVE</b>To evaluate the efficacy of sildenafil on nocturnal penile tumescence (NPT).</p><p><b>METHODS</b>Thirty-five patients with erectile dysfunction (ED), 28 cases of organic ED and 7 cases of psychogenic ED, were treated with sildenafil 100 mg before bedtime. The NPT of the patients was observed by using NEVA.</p><p><b>RESULTS</b>Erectile function significantly improved in the 28 cases of organic ED (P < 0.05), but not in the 7 cases of psychogenic ED (P > 0.05).</p><p><b>CONCLUSION</b>Sildenafil can improve NPT of organic ED patients without sexual stimulation.</p>
