The state of the concentration function of the kidneys after cystectomy
The state of the osmoregulatory function of the kidneys was studied in patients with malignant neoplasms of the urinary bladder, as well as in those who had undergone cystectomy with various methods of urine diversion. The most pronounced disorders of the components of the osmoregulatory function of the kidneys were established after ureterocoloanastomosis: hypoosmia, decreased osmotic concentration of urine and osmolar clearance. After urethrocutaneostomy, hypoosmia occurs, a decrease in the osmotic concentration of urine. The greatest threat to the body in both cases is hypoosmia. After replacing the bladder with a segment of the intestine, the osmotic pressure of the plasma does not change. From a functional point of view, a rational way of urine diversion is the formation of an artificial bladder from the intestinal segment.
