Abstract


Background: This study examined our experience with one year follow-up of 20 cases of vesicoureteric reflux in children after treatment with Macroplastique® injection.

Patient and Methods: A total of 20 children (31 ureters) with primary grades II to V vesicoureteral reflux were treated with subureteral Macroplastique® injection from 2010 to 2011 and followed for an average of 12 months (range 3 to 24). Vesicoureteral reflux was grade II in 3, III in 7, IV in 9 and V in 12 ureters. Each child underwent pre-operative voiding
cystourethrography, abdominopelvic ultrasound, urine analysis/culture, S. creatinine and CBC. Dimercapto-succinic acid scan (DMSA scan) and magnetic resonance urography (MRU) were done in some patients. Voiding cystourethrography at 3 months was done to rule out persistent reflux.

Results: Overall, reflux was corrected in 11 (35.5%) ureters and 9 (45%) children after a single injection. With repeat injection, reflux was corrected in 16 (51.6%) ureters and 11 (55%) children, reflux improved/downgrade in 4 (12.9%) ureters and 2 (10%) children. Correction by grade was 100%, 100%, 9.7%, 9.7% for grades II to V, respectively. There were no surgical complications. None of the cured patients had recurrent reflux during follow-up. There were 9 (45%) children who required open ureteral  re-implantation for failed injection.

Conclusion: Sub-ureteral Macroplastique® injection therapy could be a
primary treatment for low grade VUR (grade III or less) in children because it is simple, safe, effective, less invasive, decreased.
