Diagnostic Role of Dopplerography of Renal Vessels in Patients with Late Dysfunction of the Transplanted Kidney

Aims: Search for non-invasive methods for diagnosing late transplant kidney dysfunction, which can improve control and monitor the condition of the kidney transplant, characterization diagnostic role of dopplerography of renal vessels in patients with late dysfunction of the transplanted kidney.

Study design: When conducting dopplerometry, blood flow indices were analyzed from 3 to 6 cycles of heart contractions, followed by an averaged indicator. In addition, the linear blood flow velocity was assessed separately from the renal vein.

Place and Duration of Study: For the period 2016-2017 Ultrasound of an allopod was performed in 60 recipients of RT (RENAL TRANSPLANT) in the late postoperative period.

Methodology: The average age of the patients was 38.89 ± 1.52 years. There were 34 men (56.6 7%), 26 women (43.33%). All patients were divided into two groups: patients with preserved function and patients with RT (RENAL TRANSPLANT) dysfunction. Related kidney transplantation (RRT) was performed in 55.0% of patients, in 45.0% - cadaveric kidney transplantation (CKP). The groups were comparable in the main clinical and demographic parameters.

Results: The reverse dynamics was observed when examining the level of the renal filtration function indicator, the estimated glomerular filtration rate (SKF) - at a TAMX level of more than 15 cm/sec, glomerular filtration was 51.18 ± 1.93 (47.32-55.04) ml/min (p <0.01), and with a decrease in TAMX of less than 15 cm/sec, the level of SKF decreased significantly, more than twice, to the level of 25.40 ± 2.19 (21.02-29.78) ml/min <0.001).

Conclusion: The determination of dopplerographic parameters for TP with preserved and especially with impaired depuration function with a direct assessment of TAMX opens up wide opportunities in non-invasive assessment of RT (RENAL TRANSPLANT) changes, identification of developing complications, as well as improved transplant survival.
