Abstract:
Different complications may occur within months or years following kidney transplantation such as Renal artery thrombosis, Arterial stenosis which associated with the abrupt onset of hypertension, venous thrombosis, infection ureteral obstruction, fibrosis and nephrolithiasis. Ultrasound is the most valuable noninvasive imaging modality used in monitoring renal transplant. Duplex Doppler ultrasound is of particular value in detecting early signs of rejection and may be preceding the deterioration of the renal function estimated by serum creatinine by two days. Resistive Index (RI) obtained by Doppler spectral waveform analysis might give an important idea about the function of the transplanted kidney.Aims of the study : 1.To correlate between the serum creatinine level and the Resistive Index .2. Estimate a reliable and applicable way in the assessment and follow up of transplanted kidney function by gray scale ultra sound and Doppler ultrasound.Patients and Methods : A cross sectional study conducted at the radiology department of Al - Shaheed Ghazy Al - Hariri teaching hospital and the kidney transplantation center, during the period from 17th of August 2013 to the 30th of June 2014. A total of 45 patients with renal transplant of less than one year duration, and agreed to participate were recruited in this study regardless their age and gender and should have a recent serum creatinine test report prior to inclusion. Data were collected via direct interview with the patients using a data collecting sheet including ; the age, sex, duration of transplantation, laboratory data, including blood urea and serum creatinine, Ultrasonography and Doppler examination findings. All patient were examined, through aXIItransabdominal approach and in supine position for estimation of the resistive index of the transplanted kidney. The study protocol was approved and all official agreement were obtained in addition to the verbal consent of the patients. Statistical analysis was performed by using the statistical package for social sciences version 18, and the appropriate statistical tests were applied accordingly.Results : The mean age of the patients was 38 ± 9years (range, 17 to 65 years). The mean of RI was (.88 ± .96), it was normal in (33.3%) of the patients and high in (66.7%). The mean serum creatinine was 2.5 ± .47 and mean blood urea was 96 ± 8.6. Resistive index correlate significantly with serum creatinine , bloodurea, kidney size ,echogenicity and cortical thickness; P<0.05.Conclusion : A significant correlation had been found between Resistive index and each of serum creatinine and blood urea levels in transplanted kidney. There is a significant relationship between Resistive index value and duration of renal transplantation in transplanted kidney. Introduce the Doppler ultrasonography in the assessment of renal transplants as routine postoperative examination beside the lab renal function test and further prospective studies including larger number of patients are suggested
