[Increase in transplant volume--a prognostic sign of threatened kidney rupture?]

In 58 patients the volume of the kidneys was established by continuous sonographies of the grafts during the first 25 days after operation. In non-rejecting patients it increased on average by 20%, in rejecting and rupturing patients by 35%. The transplants with rupture of the parenchyma revealed the greatest increase to the volume maximum per time unit. The sonography is a suitable screening method for the purpose of rejection diagnostics and can give prognostic statements concerning the threatening rupture of the parenchyma. Rapid increase of the volume, proof of an obstruction of the micturition and constantly high blood pressure levels indicate a threatening rupture of the transplant.
