The Healthcare Costs of Kidney Stones

With the increased attention on the rapidly increasing cost of healthcare, we decided to take a closer look at how much kidney stone disease costs in the United States.

United States healthcare expenditures for kidney stone disease for the year 2000 (most recent available published data).

Underlying the costs for kidney stone treatment is how common stone disease is, with about 1 in 10 Americans experiencing a stone during their lifetime. That results in a lot of clinic and emergency room visits, trips to the operating room, and prescriptions for pain control medication. Additionally, because stone disease often afflicts working aged adults, there are also large costs incurred due to lost work hours.

Where is the money going?

About half of the healthcare expenditures for stone disease was due to inpatient hospital costs, which includes surgeries requiring hospitalizations and admissions to the hospital for stone related problems. Other costs included clinic visits, outpatient procedures, emergency room visits, radiology examinations, and prescription drugs. The estimated average healthcare cost for each stone patient for the year amounted to $6,532 dollars. This is considerably higher than the average healthcare cost of $3,308 for non-stone formers during the same year. Note that these figures refer to costs for health insurers. The “out-of-pocket” costs for an uninsured individual will be higher, sometimes significantly more.

Cost of surgeries

About 25% of stone patients require surgical treatment each year. Of the surgical options available, percutaneous nephrolithotripsy was the most expensive approach, as measured by cost by procedure, with shockwave lithotripsy and ureteroscopy coming in second and third. The dollars figures shown below were for the year 2000 and reflects expenditures by insurance companies. Out-of-pocket costs for an uninsured patient will be higher.

Average cost of stone surgeries:

PCNL: $3,624

ESWL: $2,295

Ureteroscopy: $1,425

Costs due to lost work:

In 2000, 1% of all working age adults missed work due to a stone episode. When focusing on just stone formers, 30% of them missed work due to a stone episode, with each worker losing an average of 19 work hours over the year, or 3.1 million lost workdays for the entire working population. Estimating an average U.S. hourly wage of $24 an hour, that equates to $456 of wages lost per worker. From an employer’s standpoint, the estimated indirect costs due to stone disease was $775 million dollars a year. Unmeasured here are other potential costs, such as childcare, transportation, and lost work by family members that might be incurred during trips to the emergency room, clinic, or operating room.

    Is there anyone in the Southern Ontario area with Medullary Sponge Kidneys. I am interested in knowing if they encountered the same medical roadblocks that I have. There is a doctor in Michigan who performs a surgery that helps eleveate problems associated with MSK. Of course they do not cover the procedure in Ontario and I am not financially able to afford to pay to see this doctor on my own, or I would immediately. I just want to be able to live my life, work and be a mother who is active and able to do my daily duties. It is very frustrated to suffer and feel there is no end in sight and no way to be treated for this debilatating condition.
