The problem with this autosomal recessive condition arises from a malfunction in the process of reabsorption. Cystine filtered from the renal glomerulus cannot be reabsorbed from the proximal tubules. Therefore, due to its extremely low solubility at normal urine pH, it precipitates and causes stone formation. Recurrent stone formation is the most prominent clinical presentation of cystinuria. The patients usually present with a renal colic episode with concomitant nausea and hematuria. The aim of medical treatment is to maintain the solubility of cystine in urine. The main strategies are to increase urine volume and urinary pH. Potassium citrate or potassium bicarbonate can be used to raise the pH of the urine to 7.5 to increase cystine solubility. If the treatment with alkalinization and higher urine output fails, cystine binding agents such as tiopronin and D-penicillamine can be added to the treatment. Surgical management of pediatric patients with cystine stones is similar to that in the adult population. However, cystine stones can be resistant to ESWL. Retrograde ureteroscopy with semirigid and flexible instruments is a good option for ureteral stones and also for renal stones less than 20 mm in diameter. The golden standard option for high-volume stones larger than 20 mm in diameter is percutaneous nephrolithotomy (PCNL).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Cystinuria is the primary hereditary factor contributing to the formation of kidney stones throughout childhood. It is a genetic disorder that typically manifests as recurrent stone formations. The aim of the treatment of genetically caused pediatric stone diseases is to prevent stone formation with medical treatments, remove existing stones through surgical treatments, and mitigate the risk of developing chronic kidney disease in the future.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00345-025-05604-6","type":"journal-article","created":{"date-parts":[[2025,4,15]],"date-time":"2025-04-15T14:37:56Z","timestamp":1744727876000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Cystinuria in children: diagnosis and treatment"],"prefix":"10.1007","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2370-548X","authenticated-orcid":false,"given":"Mehmet \u0130lker","family":"G\u00f6k\u00e7e","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6917-9051","authenticated-orcid":false,"given":"Murat Can","family":"Karaburun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,4,15]]},"reference":[{"issue":"8","key":"5604_CR1","doi-asserted-by":"crossref","first-page":"1705","DOI":"10.1007\/s00467-021-05342-y","volume":"37","author":"V D'Ambrosio","year":"2022","unstructured":"D\u2019Ambrosio V, Capolongo G, Goldfarb D, Gambaro G, Ferraro PM (2022) Cystinuria: an update on pathophysiology, genetics, and clinical management.
