Urodynamic evaluation of primary nocturnal enuresis in adolescents

ABSTRACT

To evaluate adolescent cases of primary nocturnal enuresis using clinical and urodynamic assessment for detection of the underlying aetiology. Between may 2004 and December 2005 this work was carried out on 50 enuretic patients with a mean age of 15.7 years [range 14.5-16.5 years] 26 males and 24 females, all patients were subjected to full history taking including enuretic history, a voiding diary, family history was also taken. A thorough physical examination including neurological examination was done. Investigations were also done including urine analysis, KUB film, pelviabdominal ultrasonography. Urodynamic assessment was also done for all the patients, including uroflowmetry and voiding cystometry. Repeated bedwetting at night occurring in 20 cases [40%]. Polyuria in 3 cases [6%] and urgency in 3 cases, a poisitive family history in one patient. Neurologically signs of neurologic disorders in 3 cases; urodynamically 1 patient showed obstructive flow, overactive bladder detected in 18 patients, 17 of them polysymptomatic and one case was monosymptomatic. persistence of primary nocturnal enuresis into adolesency may indicate an underlying aetiology especially in the polysymptomatic patients
