Kidney Drainage Pressure Study

Maryland rates for HCPCS 50396

A pressure study carried out through a drainage tube that already runs into the kidney or the tube leading from it. Fluid is run in at a steady rate while the pressure inside is recorded, showing whether urine drains freely or is meeting resistance. The readings help decide whether a suspected narrowing is genuinely blocking flow and needs treatment.
