[A modified method of nephropexy (an experimental study)].
The aim of the study was design of an experimental model for more reliable nephropexy. The experiments were performed on 35 mongrel dogs divided into three groups. In group 1 the right kidney was separated under general anesthesia, in its subcapsular tunnels the tension-free vaginal tape made of polypropylene (PPT) was inserted and knotted to the 12th rib. The excretory function and micromorphological state of the kidneys were examined during six months. In group 2 (control) only subcapsular tunnels were created followed by micromorphological examination of the kidneys. In group 3 after fixing the kidney, as described above, the duration of fixation was evaluated by means of dynamometry. The PPT inserted subcapsularly and knotted to the 12th rib caused a light aseptic inflammation which resulted in firm adhesion of the tape to the fibrous capsule and external surface of the kidney and their safe fixation able to stand an effort up to 6.6 +/- 0.4 kg. The above method of nephropexy can be recommended for clinical use by means of open, laparoscopic or retroperitoneoscopic approaches.
