Abstract
Vesico-ureteral reflux (VUR) in patients with neurogenic lower urinary tract dysfunction (NLUTD) can either be due to reasons unrelated to NLUTD, like morphologic changes, or can develop as a secondary complication of NLUTD, e.g. due to elevated pressures during storage and/or voiding, or due to bladder wall fibrosis. Cystography remains the gold standard for diagnosis of vesico-renal reflux. The most commonly used grading system distinguishes lower grade reflux (reflux grade I = does not reach the renal pelvis, grade II = reaches the renal pelvis, but no dilatation; grade III = mild dilatation of the collecting system, normal/minimally deformed fornices) from higher grade reflux (grade IV = moderate dilatation of the collecting system, blunt fornices; grade V = marked dilatation of the collecting system/hydronephrosis) [1].
