Refractory Salmonella enterica serotype choleraesuis-related renal cyst infection in a patient with autosomal dominant polycystic kidney disease undergoing hemodialysis treated successfully with intracystic ciprofloxacin infusion.

OBJECTIVE

To report a potential salvage therapy for refractory renal cyst infection secondary to Salmonellaenterica serotype choleraesuis (S. choleraesuis).

CLINICAL PRESENTATION AND INTERVENTION: A 52-year-old male with autosomal dominant polycystic kidney disease undergoing hemodialysis experienced an episode of S. choleraesuis-related gastroenteritis subsequently complicated by bloodstream and refractory renal cyst infection with formation of multiple pyocysts. The patient was treated with intracystic indwelling diluted ciprofloxacin solution.

CONCLUSION

In this patient, intracystic infusion of ciprofloxacin achieved a sufficient antibiotic level in infected renal cysts and hence completely eradicated S. choleraesuis. Therefore, intracystic antiobiotic infusion could be a potential salvage therapy for refractory renal cyst infection.
