“…Congenital urinary system anomalies have an overall prevalence of two per 1000 live births4, and represent a significant proportion of fetal pathology detected by ultrasonography5. However, antenatally diagnosed nephrolithiasis has only been described once before in the literature6. In that report, fetal nephrolithiasis was diagnosed at 33 weeks' gestation in one twin, and confirmed on the fourth day of life.…”

IntroductionAlthough pediatric urolithiasis is an established entity, its antenatal diagnosis is rare. We hereby report a case detected at 20 weeks gestation and discuss the etiopathogenesis, predisposition, and surveillance following intervention.Case reportA 2-year-old girl with left renal pelvic calculus detected antenatally at 20 weeks was evaluated. Left hydronephrosis, obstructive pelvic calculus with a decrease in differential renal function on ethylene dicysteine (EC) renogram was confirmed. The metabolic workup was normal. Following stone extraction by left pyelolithotomy, a left ureteropelvic junction obstruction secondary to a mucosal valve was apparent which was excised and left pyeloplasty was done. Stone analysis revealed 100% cystine. Differential renal function and drainage improved post-surgery. The child, however, did not have a follow-up in the interim and presented with a recurrent stone one and a half years later.ConclusionKnowledge of antenatal urolithiasis ensures continued follow-up, evaluation for metabolic disorders, and associated structural defects, especially with increasing stone size and increasing hydronephrosis. This helps in timely intervention and continued surveillance.
