Pre‐ and postoperative sonograms were reviewed in 59 children who underwent ureteral reimplantation to assess the frequency, location, extent, and evolution over time of focal thickening of the posterior bladder wall and bladder base after reimplantation. The interval between reimplantation and follow‐up sonography ranged from 2 weeks to 12.36 years (mean, 1.29 years). Thirty‐two patients (54.2%) had focal thickening of the posterior bladder wall and trigone after reimplantation. The earlier after reimplantation the children were first evaluated with sonography, the much more frequently was thickening observed. Thirteen had fusiform thickening along the submucosal tunnel and twenty‐four had a hyperechoic nodule at the trigone. The thickening resolved in one third of the children and is presumed to have represented postoperative edema in these cases. However, on the sonographic appearance alone it was not possible to differentiate transient changes resulting from postoperative edema from those representing developing fibrosis or granuloma formation.
