Objectives: Evaluation of the incidence of urological abnormalities as revealed by urological examinations of a large number of patients with enuresis.
Methods: Patients with the chief complaint of nocturnal enuresis were examined urologically.
Results: The incidence of urological abnormalities was 1.8% of 940 patients on intravenous pyelography (IVP), 7.1% of 695 patients on voiding cystourethrography (VCG) and 11.5% of 487 patients on cystometry (CM). No abnormal findings were observed in 58 patients on renal ultrasonography (US). 92.1% of reflux cases detected by VCG were low grade and only 8.9% of patients with reflux had pyuria. 20.2% of 446 patients who were submitted to all these examinations had some urological abnormality. Only pollakisuria was statistically more frequent in patients with urological abnormalities than in patients without them.
Conclusion: These data suggest that the incidence of urological abnormalities was rather low when compared with the past literature. In particular, IVP was though to be unnecessary.
