[Analysis of vesicoureteral reflux (VUR) course in children].

UNLABELLED

A small number of reports evaluating early effects of vesicoureteral reflux conservative therapy in children, based on antibacterial prophylaxis combined with correction of the of lower urinary tract function inspired us to perform the study. THE AIM OF THE STUDY was to assess the effects of vesicoureteral reflux (VUR) management in children according to grade, sex and way of treatment.

MATERIAL AND METHODS

The study group consisted of 108 children, who were treated in 2000-2007 due to VUR. There were 162 refluxing ureters (grades I-V) diagnosed by voiding cystourethrography (VCU). In 82 children cystometry and (or) uroflowmetry were additionally performed, which revealed lower urinary tract disorders in 41 (60 refluxing ureters), mostly detrusor hyperactivity or detrusor-sphincter dyscoordination. All children had conservative treatment, A - in 67 (102 refluxing ureters) only antibacterial prophylaxis, B - in 41 of children (60 refluxing ureters) in combination with pharmacological treatment of urodynamic abnormalities.

RESULTS

The check-up VCU was performed after 23+/-15 months on average. VUR was observed to subside in 44/162 (28%) of refluxing ureters, including 22/108 (22%) of those treated managed with method A and 22/60 (37%) with method B. Fifty three of refluxing ureters were qualified for further conservative therapy and 65/162 (40%) for surgery (especially endoscopic). Following 2-3 years medical and surgical treatment, 87/162 (54%) refluxing ureters resolved.

CONCLUSION

In the diagnostics of VUR in children we should take into consideration the assessment of lower urinary tract function, as treatment of these abnormalities increases the effects of VUR conservative management. However it should be confirmed on a larger group of patients.
