Is there a correlation between the size of the BCG scar and renal scar of urinary tract infections in children?

Zusammenfassung: | Objective: Pyelonephritis cause cellular death, and development of scars in kidneys. The aim of this study is to demonstrate a correlation (if any) between renal scar, and size of the scar induced by BCG vaccine in children who had experienced urinary tract infections. In case of detection of any correlation, BCG scar formation can be used as a determinative marker of renal scars, which develop following urinary tract infection. Methods: Patients with a history of urinary tract infection at least 4 months old who had undergone 99mTcDMSA scanning were included in this study. Vertical and horizontal diameters of BCG scars of the patients in the study group were measured. For statistical analysis the greatest diameter was taken into consideration, and the patients were divided into 2 subgroups based on the greatest diameter of their BCG scars (Subgroups 1, ≤5 mm, and 2, >5 mm). The patients were also evaluated in 2 groups as those with (Group 1) or without (Group 2) scars. Both groups were compared with subgroups with the largest scar diameters of ≤ 5mm or >5 mm Results: Study population included 108 (82 girls) patients. DMSA detected scars in a total of 51 patients. Mean ages of the patients with and without scars were not different (p=0.414). No significant difference was found in size of the BCG scars between renal scar positive and negative groups (p>0.05). Conclusion: No correlation was found between development of renal scar and the size of BCG scar in children after urinary tract infection. |
