We initially treated the patient with antibiotic therapy, urinary diversion, and oral acidification with acetohydroxamic acid, achieving negative urinary cultures. Because of the persistence of encrusted pyelitis, the patient was discharged on oral l-methionine 500\u2009mg bid and 12 months later the encrustations had almost disappeared. Finally, we performed right retrograde intrarenal surgery to remove a persistent small calcification.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Oral urinary acidification with l-methionine is a valid treatment for urinary encrustations in EU, with no complications reported.
