About the department

The department of nephrology at Memorial Sisli Hospital Istanbul provides a full range of diagnostics and treatment for acute and chronic kidney diseases, including systemic kidney diseases, as well as preoperative and postoperative care for kidney transplant patients. To determine the optimal treatment tactics, the patient needs a comprehensive examination - the department has a vast arsenal of diagnostic capabilities to assess the condition and function of the kidneys. Then, depending on the specific diagnosis, the department's doctors consider possible treatment methods. First-line treatment is pharmacotherapy with modern drugs. If such therapy is ineffective, the patient is recommended renal replacement therapy (dialysis). The department enjoys a reputation as the largest and best medical institution of its kind in Turkey. The department provides medical care in both inpatient and outpatient settings. In their work, doctors are guided only by modern clinical protocols and follow the recommendations of professional societies, thanks to which they achieve high rates of treatment success and restore patients' health.

One of the department's priorities is the treatment of patients with autoimmune and non-autoimmune systemic diseases, such as vasculitis or amyloidosis. In addition, the department offers competent medical care to patients with kidney disease in diabetes mellitus. The therapeutic possibilities of the department cover all extracorporeal renal replacement therapy procedures, such as hemodialysis, peritoneal dialysis, special plasmapheresis procedures, immunoadsorption and others.
