“…Compared to the adult population, UL in children does not significantly vary by sex and recurrences are more frequent, reaching up to 20% [8]. Predisposing factors can be found in more than 70% of children with UL, primarily including metabolic disorders (hypercalciuria, hypocitraturia, hyperoxaluria, hyperuricosuria, cystinuria), recurrent UTIs, and congenital malformations [8][9][10].…”

“…Staghorn calculi may be associated with recurrent UTIs, mainly of Proteus sp. etiology, with less frequent associations with Providencia sp., Klebsiella sp., Pseudomonas sp., Morganella morganii, Citrobacter, Staphylococcus aureus and enterococci [8,10,11]. These bacteria produce urease, which breaks urea down, producing ammonium ions and carbon dioxide.…”

“…These bacteria produce urease, which breaks urea down, producing ammonium ions and carbon dioxide. This process leads to urine alkalinization, which provides favorable condi-tions for the crystallization of struvite crystals (ammonium magnesium phosphate stones) and apatites (calcium phosphate stones) [2,4,10]. Rarely, staghorn calculi are formed as a result of metabolic disorders -from uric acid, calcium oxalate or cystine [8].…”

Infectious urolithiasis is a relatively rare form of urolithiasis in children. The predisposing factors in the pediatric population mainly include urinary tract defects and neurogenic bladder. Here we present a case of a 3-year-old boy with staghorn calculi, diagnosed during the diagnostic management for persistent leukocyturia. The boy had a history of recurrent urinary tract infections (rUTIs) caused by Proteus mirabilis and Klebsiella pneumoniae. Based on laboratory tests and imaging studies, the patient was diagnosed with a dysfunctional right kidney and a significant risk due to a large staghorn calculus to the left kidney. Bilateral ureteroscopic lithotripsy was performed, the deposit from the left kidney was removed via open surgery, and the narrowed sections of the ureters were excised. During the follow-up period, the patient's glomerular filtration rate remained normal. In the case of rUTIs kidney calculi may be diagnosed incidentally as they produce no clear clinical symptoms.
