Follow-up visits
The first follow-up visit was on the first postoperative day. After removal of the catheter in the morning, patients were seen for a physical examination, uroflowmetry and ultrasound including PVR measurement. Further visits in the ambulatory setting were arranged 1, 3 and 6 months after the intervention. The follow-up visit at 6 months was composed of an additional urodynamic study and MRI of the pelvis as a comparison with the baseline visit.
