UNILATERAL CYSTINE STONE IN FEMALE ADULT PATIENT: CASE REPORT

Yousef Bada*

ABSTRACT

Cystinuria, a rare genetic disorder, leads to the formation of cystine stones, with a subset of patients developing stones exclusively in one kidney. While cystine stones are more frequently observed in bilateral formations, unilateral cases do occur, and understanding why stones form unilaterally in some individuals remains unclear. We report a case of a 35-year-old female presented with right flank pain and lower urinary tract symptoms and was found to have a 5 cm right renal stone. Following open surgical removal at Tishreen University Hospital, the stone was confirmed to be pure cystine. Her 24-hour urine cystine level was 620 mg/L. Post-operatively, she was treated with potassium citrate and increased fluid intake.
