Objective To decrease the detrusor leak-point pressure (LPP) of > 40 cmH2 O in children with a neurogenic bladder, using the α1 -adrenergic blocking agent alfuzosin. Patients and methods Videocystometry was used to measure the detrusor LPP and several other variables before and 3 weeks after the oral administration of alfuzosin (2.5–7.5 mg/day) in 17 children (mean age 6.3 years) with an upper motor neurone lesion. Results The mean (sd) detrusor LPP decreased from 68 (37) to 46 (31) cmH2 O (P < 0.01), reflex volume (defined as the volume at the first uninhibited bladder contraction of > 15 cmH2 O) increased from 78 (69) to 112 (118) mL (+ 44%), bladder compliance increased from 9.3 (6.1) to 19.6 (14.6) mL/cmH2 O (+ 111%), maximal vesical pressure decreased from 84 (40) to 70 (47) cmH2 O (- 17%), and the mean number of uninhibited bladder contractions decreased from 6.3 to 3.5 (- 44%). The therapy was well tolerated; side-effects were rare and not severe. Intermittent catheterization could be avoided in six children. Conclusion Alfuzosin decreases the detrusor LPP in children with a neurogenic bladder caused by an upper motor neurone lesion, significantly and therapeutically, and should be considered as an alternative or addition to intermittent catheterization and anticholinergic drugs in selected patients.
