A study of etiological factors of nocturnal enuresis

ABSTRACT

Primary nocturnal enuresis represented 62.9% of the cases [males 60.7%,females 39.3%]. Most of them were from big families [70.2%] and low socioeconomic levels [73.8%]. Maximum functional bladder capacity was estimated for patients and controls. Those with primary nocturnal enuresis showed a sig. Smaller [P 0.005] maximum functional bladder capacity than controls, while patients with secondary nocturnal enuresis showed no sig. difference from controls. Urodynamic studies were done for 10 cases presented with primary nocturnal enuresis and recurrent urinary tract infection. It revealed a hyperreflexic bladder in 8 cases which increases the intravesical pressure and impair renal and ureteral drainage leading to recurrent attacks of urinary tract infection. They showed favourable response after 2 weeks treatment with an anticholinergic drug [propantheline bromide] following treatment of urinary tract infection
