Objective To investigate the pitfalls of measuring post‐void residual urine volume (PVR) in patients with orthotopic neobladders, in an out‐patient clinic. Patients and methods Fifteen patients with orthotopic neobladders were enrolled in the study; five patients had a colonic neobladder, five an ileocolic neobladder and five a sigmoid neobladder. The PVR was compared after measuring by catheterization under fluoroscopic monitoring after normal or forced voiding. Results The PVR after forced voiding was always less than that after natural voiding, regardless of the type of neobladder. Conclusions Patients with orthotopic neobladders may have a higher PVR after voiding naturally at home than when the PVR measured in hospital.
