[Is the urodynamic assessment of enuresis in young adults justified?]

Primary or secondary nocturnal enuresis in adults (over the age of 15 years) is rare, but is associated with considerable psychosocial repercussions. The aim of this retrospective study was to determine whether urodynamic studies have any predictive value for the efficacy of the treatments proposed in these patients. This study was based on 20 patients (8 females and 12 males) between the ages of 15 and 33 years (mean: 23.75 years), studied between 1982 and 1990 with a mean follow-up of 13.35 months. Enuresis was primary in 12 patients and secondary in 8 patients. 11 patients had already received one or more treatments without success. Patients with clinically obvious neurological disease were excluded from the study. The urodynamic assessment included water cystomanometry, water urethromanometry with a perfused catheter and uroflowmetry. In addition to the investigation of other associated disturbances of micturition, the following complementary investigations were performed: urine culture in every case, IVU and/or cystography (n = 18), cystoscopy (n = 3), renal and vesical ultrasonography (n = 1). The urodynamic assessment was abnormal in 16 out of 20 cases: marked detrusor hyperactivity (n = 15), impaired compliance (n = 6), significant urethral instability (n = 7), isolated premature urge (n = 1). 15 patients presented with diurnal disorders dominated by frequency (n = 13), urgency (n = 9) and urge incontinence (n = 4); detrusor hyperactivity was detected in every case. The abnormalities observed on the urodynamic assessment guided treatment, allowing correction of enuresis in 3/4 of cases.(ABSTRACT TRUNCATED AT 250 WORDS)
