“…Rhodes et al reported antenatal urolithiasis detected at 34 weeks gestation as an echogenic focus in the upper pole of the right kidney which persisted up to 4 months. No metabolic or structural abnormalities were noted in the child during follow-up ( 5 ). Detection of renal stone at 20 weeks gestation as in ours is the earliest reported case to date.…”

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.

“…In the absence of prematurity or hospitalization in the intensive care unit, the UNI was very rare before the age of 5 months. Only two prenatal diagnoses of the nephrocalcinosis was reported in the literature [6,7]. The major symptom is the urinary-tract infection.…”

There are few publications about urolithiasis of the new born baby and infant (UNI). The UNI represents 20% of the pediatric urolithiasis. The etiologies in this age group are chiefly dominated by the urinary-tract infections and metabolic abnormalities. The purpose of this paper was to investigate the epidemiological and clinical characteristics of infant urolithiasis and to define the various treatment modalities adapted to this age group.
