The importance of 99Tcm-DMSA renal scintigraphy in the follow-up of acute pyelonephritis in children

Time course of transient cortical scintigraphic defects associated with acute pyelonephritis

“…These findings contrast with earlier reports of persistent defects being present in 50-80% of children following acute pyelonephritis [2,10,11,12]. The follow-up investigations for many of these patients occurred within 6 months of their UTI.…”

“…Some experts have suggested as little as 2 [13] or 3 months [4,14], or as long as 6 [11,15] or 12 months [16]. Although small numbers and corresponding broad confidence intervals limit the Fig.…”

Diagnostic role of initial renal cortical scintigraphy in children with the first episode of acute pyelonephritis

“…It is usually used for the detection of the cortical defects of APN and scarring related to chronic pyelonephritis [8][9][10]. However, it is not clear whether DMSA study performed during the acute period of febrile UTI is useful for prognosis and outcome assessment of patients [11].…”

Hydronephrotic Kidney: Pediatric Three-dimensional US for Relative Renal Size Assessment—Initial Experience

“…Relative renal size and split renal function are critical factors not only initially but also during follow-up. Renal (parenchymal) growth is an essential aspect of patient treatment (2)(3)(4)(5)(6). It has been shown that US measurement of relative renal volume correlates with scintigraphically assessed split renal function in normally shaped kidneys without dilatation of the collecting system and with the absence of any acute urinary tract disease, such as an infection (7)(8)(9).…”
