Background

Childhood vesico-sphincteric disorders are the cause of functional and psychological disability. They are also responsible for serious uronephrologic complications akin to neuro-bladder complications. In this study, we looked for the clinical manifestations linked to these disorders as well as the paraclinical and urodynamic anomalies and their therapeutic management.

Methods

We carried out a retrospective and descriptive study of patients with vesico-sphincteric disorders, followed in the pediatrics department of Charles Nicolle hospital in Tunis.

Results

In total 26 patients were included in our study. The median age at the first consultation in a pediatric nephrology department was 9 years (IQR 25 = 6 years; IQR 75 = 11 years). There was a predominance of girls: 19 boys and 43 girls. The filling phase and the voiding phase were dominated by the combination of three or more symptoms. Bladder tenderness was reduced in 12% of cases. Nineteen percent of patients reported post micturition dribble in the post-voiding phase. The flow rate curve was polyphasic in 36% of cases and flat in 11% of cases. The median of the post void residual was 62, 2 mL (IQR 25 = 25 mL; IQR 75 = 102 mL). Cystometry showed reduced bladder sensation in 14% of cases, detrusor overactivity in 65% of cases, bladder hypocontractility in 8% of cases, hypocompliant bladder in 42% of cases and small capacity in 88% of cases. Sphincter dysynergia was noted in 34% of patients. Anticholinergics were the most used in the treatment of disorders (53%). Renal failure was noted in 45% of the patients of which 11% had end-renal stage failure. During follow-up 16% of our patients required kidney replacement therapy.

Conclusion

Given the seriousness of vesico-sphincteric disorders in children and the late discovery in the majority of cases at the complication stage, targeted primary prevention must be carried out based on continuous training of primary care physicians to minimize the appearance of complications involving the functional and vital prognosis of these children.
