We evaluated 50 patients who had renal transplants and were sent for Doppler Ultrasound for complications, after the transplant procedure. Ages of the patients ranged from 20 to 65 years, 39 were male and 11 were female. In inclusions only first month post op patients were included and only those patients were considered who had some sort of complications on ultrasound at some stage of the follow up.Following complications were noticed: Diminished corticomedullary demarcations, increased echogenicity with raised R I (20 pt). Perinephric collections other than haematoma (13 pt). Perinephric haematoma (06 pt). Obstructed transplanted kidney ( 05 pt). Diminished arterial vascularity of the kidney (04 pt) Renal vein thrombosis (02 pt). RI was found to be raised in increased echogenicity, obstructed hydronephrotic kidney, diminished arterial supply and was disturbed in RVT.

Aim: The present study evaluated the effect of differences in the peak systolic velocity (PSV) and resistive index (RI) in the testicular artery (TA), capsular artery (CA), and intratesticular artery (ITA) after microscopic subinguinal varicocelectomy (MSV) on postoperative pain and semen parameters. Patients and Methods: Scrotal color Doppler ultrasound (CDUS) measurements were made in 33 patients (age 18-31 years) prior to MSV and 3 and 6 months after MSV. Pain was recorded using a visual analog scale and sperm concentration was determined to analyze the predictive value of the CDUS parameters regarding surgical outcome. Results: A significant decrease in pain scores was observed in most patients at both follow-ups. The first postoperative CDUS revealed a significant increase in the TA-PSV (p<0.001) and a decrease in the TA-RI (p=0.002) and CARI (p=0.006). The second postoperative CDUS also revealed a significant increase in the TA-PSV and a decrease in the TA-RI, and the PSV in the ITA and CA and RI in the ITA and CA were significantly different from the values obtained pre-operatively and at the first follow-up. A negative correlation was found between the pain level and TA-PSV (r=-0.433, p=0.012), whereas sperm concentration positively correlated with both the TA-PSV and CA-PSV (r=0.534, p=0.001 and r=0.455, p=0.008, respectively).Conclusions: The PSV and RI are useful parameters for detecting changes in testicular microhemodynamics after MSV. In addition, the TA-PSV and CA-PSV can be used to predict improvements in pain and sperm concentration.

Limfadenopati didefinisikan sebagai sebuah abnormalitas ukuran dan konsistensi dari limfonodus yang bisa terjadi akibat proses infeksi dan inflamasi lainnya. Penelitian ini bertujuan menjelaskan nilai diagnostik USG color Doppler dan Elastografi dalam menentukan limfadenopati leher jinak dan ganas dibandingkan dengan hasil Bajah. Penelitian ini dilaksanakan di Bagian Radiologi RS Universitas Hasanuddin, Makassar yang dimulai pada bulan Februari-Maret 2018. Desain penelitian menggunakan uji diagnostik. Sebanyak 50 sampel dengan klinis limfadenopati leher. Dilakukan pemeriksaan ultrasonografi color Doppler untuk melihat pola, lokasi vascular serta nilai resistive index, kemudian dilakukan elastografi untuk menentukan elastisitas jaringan. Dilanjutkan dengan melakukan pemeriksaan Bajah untuk menentukan limfadenopati leher jinak dan ganas sete. Analisis data menggunakan statistik melalui uji diagnostik. Hasil penelitian menunjukkan bahwa dari uji diagnostik, didapatkan pola vaskuler memiliki sensitivitas 72%, spesifitas 92%, akurasi 84%, NPP 88%, NPN 81%. Lokasi vaskuler memiliki sensitivitas 59%, spesifitas 86%, akurasi 80%, NPP 92%, NPN 75%. Nilai resistive indeks didapatkan cut 0ff 0,795 dengan nilai sensitivitas 95,5%, spesifitas 75%, akurasu 84%, NPP 75% dan NPN 95,5%. Apabila dibandingkan dengan USG color Doppler dan elastografi, maka elastografi jauh lebih unggul dalam menentukan limfadenopati leher jinak dan ganas dengan sensitivitas 95,4%, spesifitas 96,4%, akurasi 96%, nilai prediksi positif 95,4% dan nilai prediksi negatif 96,4%.   Lymphadenopathy is defined as an abnormality in the size and consistency of the lymph nodes that can occur due to other infections and inflammatory processes. This study aimed to determine the diagnostic value of ultrasound color Doppler and Elastography in determining the benign and malignant cervical lymphadenopathy compared with the results of the elephant Research method. This research was conducted in Radiology Department of Hasanuddin University Hospital, Makassar which started in February-March 2018. The research design used the diagnostic test. A total of 50 samples with clinical cervical lymphadenopathy. The color Doppler ultrasound examination was conducted to find out the pattern, vascular location and resistive index value, then the elastography was performed to determine the elasticity of the tissue. After that, a FNA examination was done to determine benign and malignant cervical lymphadenopathy. The data analysis used the statistic through the diagnostic tests. The research results indicated that the diagnostic test revealed the vascular pattern of 72% sensitivity, 92% specificity, 84% accuracy, NPP 88%, NPN 81%. The vascular site had a sensitivity of 59%, specificity 96%, accuracy of 80%, NPP of 92%, NPN of 75%. The resistive values index obtained 0ff 0.795 with 95.5% sensitivity, 75% specificity, 84% accuracy, 75% NPP, and 95.5% NPN. When compared with Doppler ultrasound and elastography, the elastography was superior in determining benign and malignant cervical lymphadenopathy with 95.4% sensitivity, 96.4% specificity, 96% accuracy, 95.4% NPP and NPN of 96.4 %. Thus, Doppler ultrasound and elastography had high diagnostic values, which could be used to determine both benign and malignant cervical lymphadenopathy.
