Patients with spinal injury were excluded. We compared the correlation between prostatic urethral length and total prostate volume (TPV<\/jats:styled-content>). We also evaluated the postoperative postvoid residual (PVR<\/jats:styled-content>) and presence of pyuria, and reviewed postoperative complications and unassisted urination ability.<\/jats:p><\/jats:sec>Results<\/jats:title>We found a positive correlation between prostatic urethral length and TPV<\/jats:styled-content>. After the insertion of the M<\/jats:styled-content>emokath stent, the catheters were removed from all patients who could urinate unassisted. The PVR<\/jats:styled-content> was <50\u2009mL in 76.4% patients, and there was a 52% improvement in pyuria after insertion of the M<\/jats:styled-content>emokath stent. The mean postoperative follow\u2010up duration was 33.2\u2009\u00b1\u200916.7 months. A total of 21 patients (56.7%) were able to urinate unassisted after receiving the M<\/jats:styled-content>emokath stent. Unassisted urination was difficult in patients with poor performance status. No serious complications were observed after insertion of the M<\/jats:styled-content>emokath stent.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>The M<\/jats:styled-content>emokath stent was safe and useful for elderly patients with urethral obstruction and good performance status requiring long\u2010term management with urethral F<\/jats:styled-content>oley catheters.
