“…The diagnostic work-up should begin with an accurate assessment of the clot burden. Ultrasonography is the first mandatory diagnostic imaging, while low-dose computed tomography (CT) should be preferred in case of trauma [ 5 , 6 ].…”

Intravesical Agents in the Treatment of Bladder Clots in Children

Bladder blood clots represent an infrequent urinary condition in children. They usually result from hematuria with many underlying causes, such as urinary tract infections and urethral/bladder traumas. Treatment options for clot removal include trans-urethral or suprapubic bladder irrigation and, if unsuccessful, endoscopic management under general anesthesia with a resectoscope. In younger male children, however, the repeated passage of a trans-urethral resectoscope may be challenging and traumatic, due to the small lumen diameter. Eventually, an open surgical approach can be required in many patients. Few anecdotal non-surgical approaches have been proposed for the management of bladder blood clots in children. This review aims to summarize the conservative techniques described in the literature with the instillation of intravesical agents, analyzing the different strategies and their advantages.

The prevalence of hypercalciuria in children is 3%–10% globally and up to 35% in the United States. Hypercalciuria in children has many presentations; it causes different metabolic disorders and can negatively affect a child's growth. It also increases the risk of low bone mineral density and urinary tract infections. In addition, it is the most widespread cause of persistent microscopic hematuria. Changes in the diet and medications in cases of advanced stage can be useful to prevent further complications. This study aimed to determine the prevalence of hypercalciuria and to investigate its relationship with different factors in children aged 2–16 years with asymptomatic microscopic hematuria in 2020 in the Children's Medical Center hospital. This retrospective cross‐sectional study was performed in a population of children aged 2–16 years old with asymptomatic microscopic hematuria who were referred to the Children's Medical Center clinic in 2020. Data such as age, sex, serum creatinine level, and proteinuria were extracted from the patient's medical records, and their relationship with hypercalciuria was analyzed using logistic regression analysis. According to the inclusion criteria, 166 children with asymptomatic microscopic hematuria (72 boys and 94 girls) were included in this study. The prevalence of hypercalciuria (ratio of random urine calcium to creatinine more than 0.2) in these patients was estimated at 25% with a confidence interval of 18%–32%. In order of prevalence, the most common conditions accompanying microscopic hematuria were kidney stones, urinary tract infections, and proteinuria. The age of patients with hypercalciuria was 2 years younger on average. Each year of age increase and every 5 years of age increase between the ages of 2 and 16 years reduced the chance of hypercalciuria in this category of patients by 12% and 45%, respectively. Our findings also showed that children with a positive history of kidney stones were about 2.2 times more likely to have hypercalciuria than their counterparts, which is considered a medium effect size. Our results showed that hypercalciuria in children with hematuria is significantly related to younger age and a positive history of kidney stones.

A vérvizelés hátterében a betegségek széles spektruma állhat gyermekkorban, az egyszerű és gyorsan gyógyuló húgyúti fertőzésektől a gyorsan progrediáló súlyos glomerulonephritisig, mely a vesefunkció gyors romlásához vezet. A vérvizelés kivizsgálása során ezért elsődleges célunk az orvosi szempontból jelentős esetek elkülönítése. A vérvizeléshez társuló fehérjevizelés, a magas vérnyomás vagy a beszűkült vesefunkció progresszív vesebetegségre hívja fel a figyelmet. Amennyiben a vérvizelés makroszkópos, vagy az egyéb klinikai tünetek jellegzetesek, a differenciáldiagnózis gyakran könnyű és egyértelmű. Komplikáltabb esetekben azonban további noninvazív vizsgálómódszerek lehetnek szükségesek, mint az ultrahangvizsgálat, a vörösvértestek morfológiai vizsgálata, kalciumürítés, egyéb vizeletkémiai paraméterek, illetve a vesefunkció és a fehérjevizelés mértékének meghatározása. A családi anamnézis részletes felvétele a vérvizelés örökletes okainak elkülönítésében segít. Tünetmentes vérvizelés esetén központokként változhat a vesebiopszia elvégzésének indikációja. A glomerularis betegségek felismerésének arányát jelentősen befolyásolja, hogy mely kritériumok teljesülése esetén végzünk vesebiopsziát. Összefoglaló közleményünkben a vérvizelés diagnosztikájának kihívásait mutatjuk be. Részletezzük a vérvizelés definícióját, a glomerularis és postglomerularis vérvizelés elkülönítésének lépéseit, áttekintjük a hátterükben álló leggyakoribb betegségeket, melyek vagy gyakoriságuk, vagy gyors lefolyásuk és rossz prognózisuk miatt kihívást jelentenek mindennapi gyermeknefrológiai orvosi gyakorlatunk során.
