Poor compliance early in filling in the neuropathic bladder

A total of 30 patients with known neuropathy, mostly spina bifida, developed poor bladder compliance early in filling demonstrated urodynamically; 20 had bilateral hydronephrosis at the time of presentation and 5 also had severely impaired renal function. After appropriate treatment all of those with normal upper tracts or with bilateral hydronephrosis but normal renal function stabilised or improved. However, all 5 with severely impaired renal function progressed to end-stage renal failure. Poor compliance early in filling is an absolute indication for surgical intervention.
