[Nephroptosis in children]

The author suggests a modification of the Rivoir-Pytel-Lopatkin operation for children with II-III degree nephroptosis. It consists in careful atraumatic separation from the surrounding tissues of the whole kidney, the upper third of the ureter, and the main vessels of the kidney for a distance from its hilus to the site of their origin from the aorta and drainage into the inferior vena cava. A pedicle graft measuring 3-3.5 cm in width and thickness and 13-15 cm in length is formed from the psoas major muscle with maintained circulation. The graft is sutured to the lower pole of the kidney preserving the intactness of the capsule. Care is taken that the main vessels of the raised kidney are situated, where possible, perpendicular to the aorta and inferior vena cava. A band is worn for 12-18 months after the operation. Eight children were operated on. The late-term results in follow-up periods of 6 months to 3 years are favorable.
