Abstract:
Endoscopic subureteral injection for treatment of vesicoureteral reflux (VUR) is known to be safe and efficient due to its minimal invasive nature. Being non-migratory, non-antigenic, and biocompatible, Macroplastique (Polydimethylsiloxane) is likely to be stable over time. A 5-year-old boy with a past history of subureteral administration of Macroplastique for unilateral Grade V VUR 4 years ago presented with recurrent gross and microscopic hematuria, along with suprapubic pain. On computed tomography (CT) abdomen, calcified material, suspected to be a stone, was visualized in the bladder. On diagnostic cystoscopy, calcification was seen around the orifice site where Macroplastique injection had been performed. We removed the calcific material by Holmium laser. Endoscopic subureteric implantation has several advantages, but nevertheless, vigilance is needed to detect long-term complications, especially in patients with gross or microscopic hematuria.
