Pelvic ureteroplasty

The connection between the renal pelvis and the ureter, due to a fibrous muscle ring or occasionally ectopic blood vessels, can cause stenosis and cause hydronephrosis. If the renal parenchyma is still normal, and renal function is likely to recover, surgical methods should be used to remove the obstruction. If the hydronephrosis is severe and the renal parenchyma is atrophied, and the renal function of the contralateral side is normal, nephrectomy should be performed.
