| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To determine efficacy of alfuzosin in the treatment of children and adolescents 2 - 16 years of age with newly diagnosed or progressive hydronephrosis due to elevated detrusor LPP of neuropathic etiology.
 |  | 
| E.2.2 | Secondary objectives of the trial | 
| -To investigate the safety and tolerability of alfuzosin 0.2 mg/kg/day in children and adolescents;
 -To investigate the number of UTI episodes;
 -To investigate the pharmacokinetics (population kinetics).
 |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| Children and adolescents of either gender 2 - 16 years of age with a detrusor LPP of 40 cm water or greater and with newly diagnosed or progressive hydronephrosis grade 1 or 2 (Society of Fetal Urology) due to neuropathic bladder dysfunction. |  | 
| E.4 | Principal exclusion criteria | 
| -Hydronephrosis of non-neuropathic etiology -Patients who had an urological surgery within the last 4 months prior to the study
 -Patients who have undergone urethral dilatation within the last 3 months prior to the study
 -Patients who have received α-blocker therapy within the last 4 weeks prior to the study
 -Patients who have received any detrusor injections of botulinum toxin in the last six months
 -Patients with urological diseases/conditions other than functional bladder obstruction of neuropathic etiology that can lead to upper tract dilatation (e.g., bladder anomalies, ureterocele)
 -Patients with a history of severe respiratory, cardiovascular, gastrointestinal, metabolic, hepatic, neurologic, endocrine, or renal disease or other serious disorders, which would interfere with the interpretation of the study results
 -Patients with a history of grade 5 vesicoureteral reflux
 -Patients or parents/legally authorized representatives who are illiterate or are judged to be unable to understand the nature, scope and possible consequences of the study
 -History of known intolerance to α-blocker therapy
 -History of risk factors for Torsade de pointes (e.g., family history of Long QT Syndrome)
 -QTcF > 450 msec at screening electrocardiogram
 -History of unexplained loss of consciousness
 -Orthostatic hypotension
 -Patients who have taken potent cytochrome P450-3A4 inhibitors in the last 4 weeks prior to the study
 -Pregnant or breast-feeding females and females of childbearing potential not protected by effective contraceptive methods of birth control.
