Standard urological measures as assessed at each study visit for all enrolled patients. (i) Patients with a PVR > 350 ml were removed from the study. Patients with a PVR > 250 ml and <350 ml were scheduled for a follow-up visit within one week to monitor PVR. (ii) Patients were incapable of voluntary voiding at enrollment so the IPSS, a questionnaire assessing symptoms occurring during voiding, was not administered.
