The value of DMSA scintigraphy in the diagnostic evaluation of vesicoureteric reflux.
[The value of DMSA scintigraphy in the diagnostic evaluation of vesicoureteric reflux]. Aktuelle Urol. 2019 Oct 09;: Authors: Haid B Abstract In terms of treatment planning, the radiologic phenomenon of vesicoureteric reflux has become less important than its inherent risk of further urinary tract infections and loss of renal function. Whilst radiologic and sonographic voiding cystourethrography continues to be the gold standard in the mere detection of vesicoureteric reflux, dimercaptosuccinic acid scanning is important for risk stratification. Also it serves to confirm renal involvement in uncertain situations with urinary tract infection and fever. In older children, it is the standard in primary diagnostics. Furthermore, it enables the diagnosis of occult reflux in many cases. Therefore, dimercaptosuccinic acid scanning is an indispensable tool in the diagnostic evaluation of vesicoureteric reflux.

CONCLUSIONS: The Tc-99m DMSA scan remains the gold standard to detect renal parenchymal anomalies. A different length between the kidneys>1.11 SDS and dilated VUR are predictors of abnormal Tc-99m DMSA renal scan. PMID: 31726462 [PubMed - as supplied by publisher]
Ş Abstract Gültekin ND, Benzer M, Tekin-Neijmann Ş. Is there any relation between connective tissue growth factor and scar tissue in vesicoureteral reflux. Turk J Pediatr 2019; 61: 71-78. Vesicoureteral reflux (VUR) is the most common uropathy in childhood which leads to increased frequency of urinary tract infection (UTI) and renal scarring. Connective tissue growth factor (CTGF) plays an important role in the development of glomerular and tubulointerstitial fibrosis in progressive kidney diseases. The aim of this study was to investigate the relation between urinary CTGF and renal damage resulted from VU...
In this issue of JAMA Pediatrics, Shaikh et al continue to shed light on important aspects of urinary tract infections (UTIs) in children based on data gleaned from the Randomized Intervention for Children with Vesicoureteral Reflux (RIVUR) and Careful Urinary Tract Infection Evaluation (CUTIE) trials. The study by Shaikh et al addresses the likelihood of new renal scars developing after a first febrile UTI and after recurrent UTIs. Three decades ago, the pioneering group in Sweden identified a slight increase in renal scarring from the first UTI to the second and from the second to the third; only after 3 UTIs did the rat...
ConclusionsA bilateral duplex collecting system with refluxing upper pole moiety ureter is a very rare entity. The diagnosis should be suspected when exploring any flank pain with recurrent urinary tract infections to avoid subsequent renal impairment. Furthermore, this case shows how some common symptoms may lead to finding an unexpected urinary tract abnormality.
Conclusions: First UTI in a group of Thai children occurred in approximately equal proportion in boys and girls but boys were younger at diagnosis. Kidney and urinary tract anomalies were detected in half of the children.Urol Int
ConclusionsIn older children, the normal late DMSA scan predicted the absence of high-grade VUR, obviating the need for a VCUG. This approach could be a possible strategy for children not studied at acute infection time.
CONCLUSIONS: Compared with no treatment, the use of long-term, low-dose antibiotics may make little or no difference to the number of repeat symptomatic and febrile UTIs in children with VUR (low certainty evidence). Considerable variation in the study designs and subsequent findings prevented drawing firm conclusions on efficacy of antibiotic treatment.The added benefit of surgical or endoscopic correction of VUR over antibiotic treatment alone remains unclear since few studies comparing the same treatment and with relevant clinical outcomes were available for analysis.

Vesicoureteral reflux (VUR) is an important urologic anomaly that causes renal injury in children with febrile urinary tract infection (UTI). The present study aimed to evaluate the associations of abnormalities detected on technetium-99m-labeled dimercaptosuccinic acid (DMSA) scans, focusing on the association with VUR of the levels of relative decrease in kidney function and cortical defects after a first febrile UTI in children.
CONCLUSIONS: CIC can be deferred until continence in select infants with a low risk of significant DMSA abnormality. However, immediate initiation of CIC upon recognition of risk factors is recommended as this was associated with fewer DMSA abnormalities than delaying CIC. Recommendations for expectantly-managed patients include close follow-up, serial US and UD, and prompt initiation of CIC upon recognition of new hydronephrosis, reflux, elevated storage pressures, or febrile UTIs.

Conclusion This study shows significant renal function preservation with TUI compared to PN. However, secondary surgical interventions were higher with TUI.
