Micturition disorders were studied retrospectively in a series of 165
children over a period of 15 years. Among patients without lesions of
the upper tract at the time of diagnosis (group A, n = 131), 18 (14%)
had persistant nocturnal and diurnal enuresis; one urethral stenosis a
nd six vesicoureteric reflux required surgery; three experienced persi
stent pollakiuria and enuresis. Among patients with upper urinary trac
t damage at the time of diagnosis (group B, n = 34), seven presented w
ith recurrent urinary tract infection, five with nocturnal and diurnal
enuresis and three with urolithiasis. In the long term, only 52% of t
hem had normal renal function and two were successfully transplanted.
Micturition disorders following treatment of posterior uretral valves
are frequent and usually related to the so-called valve bladder syndro
me. Iatrogenic complications and mortality rate have dramatically decr
eased during the recent years but long-term renal function impairment
remains the most critical problem.
