Patient Services

Central Valley Nephrology (CVN) specializes in the diagnosis and treatment of diseases of the kidney and urinary system. We treat patients at all levels of disease development from those whose condition is at an early stage, detectable only by lab testing, to those patients with kidney failure requiring dialysis or transplantation. Our practice covers the entire spectrum of kidney disease.
We treat patients with the following conditions:

  • Dialysis
  • Electrolyte Disorders
  • Chronic Kidney Disease (CKD)
  • Diabetes
  • High Blood Pressure (Hypertension)
  • Anemia associated with Kidney Disease
  • Bone and Mineral Metabolism associated with Kidney Disease
  • Abnormal Protein in the Urine (Proteinuria)
  • Polycystic Kidney Disease (PKD)
  • Other Kidney Cysts
  • Blood in the Urine (Hematuria)
  • Kidney Stones
  • Inflammation of the Kidneys
  • Side effects of Medications on the Kidneys
  • Pre and Post Kidney Transplantation
  • Any Kidney Disease or Problem Nephrology Services
  • Not every patient we see progresses to kidney failure. Our job is to learn as much as we can about your particular kidney problem, explain it to you and either treat you to correct the problem or help you maintain your kidney function as long as possible. If you are one of the patients who come to us when most of your kidney function has already been lost then our job will be to help you understand your options for managing kidney failure and to guide you through preparations for dialysis and/or transplant as you choose.

    When to refer patients to us?

    There are a lot of different reasons to refer patients from the primary care practice to a nephrologist, the following list can help you identify the most important problems that we can help you with:

    • Urine albumin-to-creatinine ratio (ACR) ≥300 mg/g (34 mg/mmol)
    • Hematuria not secondary to urological conditions
    • Inability to identify a presumed cause of CKD
    • eGFR below 60 or decline of more than 30 percent in fewer than four months without an obvious explanation
    • Difficult to manage complications such as anemia requiring erythropoietin therapy and/or IV Iron infusion, and abnormalities of bone and mineral metabolism requiring phosphorus binders or vitamin D preparations
    • Serum potassium greater than 5.5 meq/L, also low potassium levels, low or high sodium and calcium levels.
    • Difficult to manage drug complications
    • Resistant hypertension
    • Recurrent or extensive nephrolithiasis
    • Confirmed or presumed hereditary kidney disease

    We are available to assist primary care physicians and other specialists in the diagnosis and care of patients at all stages of CKD. These functions include determination of the cause of CKD, recommendations for specific therapy, suggestions for treatments to slow progression in patients who have not responded to conventional therapies, identification and treatment for kidney disease–related complications, and preparation for dialysis.

    Because patients with CKD are at risk for a diverse set of adverse outcomes (not just kidney failure), referral to other appropriate specialists (eg, cardiologists for those with complex CVD) should also be considered.

    If you are a patient or a referring physician and you believe it is time to utilize our services, please contact us on the form to the right or call us at 209 (725)-2121 for nephrology services today.
