Abstract Ultrasound examination has become the “golden standard” in follow-up of the development and complications in early pregnancy. With introduction of transvaginal sonography a possibility for early morphological and biometrical ultrasound examinations has been significantly improved. The essential aim of an early pregnancy ultrasound is not only to diagnose a pregnancy, but also to differentiate between normal and abnormal pregnancy. Application of color Doppler ultrasound has enabled functional hemodynamic presentation and evaluation soon after implantation.

Vascular torsion is a rare renal transplant complication which requires prompt diagnosis and surgery to salvage allograft function. We report here a case of renal allograft torsion with interesting imaging findings on unenhanced CT and color Doppler ultrasound. A 60-year-old woman with a history of pancreas and kidney transplant presented to the emergency room with nausea, vomiting, abdominal pain, and minimal urine output. Unenhanced CT of the abdomen demonstrated an enlarged and malrotated renal allograft with moderate hydronephrosis. Color Doppler ultrasound demonstrated lack of vascularity within the allograft. The patient was taken urgently to the operating room where the renal allograft was found twisted 360 degrees around the vascular pedicle. After the allograft was detorsed, the color of the kidney returned and the Doppler signals for arterial flow improved. Intraoperative biopsy showed no evidence of infarct or acute cellular rejection. The detorsed kidney was surgically fixed in position in its upper and lower poles. Follow-up ultrasound 1 day later demonstrated normal blood flow to the renal allograft and the serum level of creatinine returned to normal.

Objective: We evaluated the effectiveness of pelvic vein embolization with aethoxysclerol in aero-block technique for the treatment of impotence due to venous leakage in men using sildenafil for intercourse. The aim of the procedure was to reduce the use of sildenafil. Methods: A total of 96 patients with veno-occlusive dysfunction, severe enough for the need of PDE5 inhibitors for vaginal penetration, underwent pelvic venoablation with aethoxysclerol. The mean patient age was 53.5 years. Venous leaks were identified by Color Doppler Ultrasound after intracavernous alprostadil injection. Under local anesthesia a 20-gauge needle was inserted into the deep dorsal penile vein. The pelvic venogram was obtained through deep dorsal venography. Aethoxysclerol 3% as sclerosing agent was injected after air-block under Valsalva manoeuver. Success was defined as the ability to achieve vaginal insertion without the aid of any drugs, vasoactive injections, penile prosthesis, or vacuum device. Additionally, a pre- and post- therapy IIEF score and a digital overnight spontaneous erections protocol (OSEP) with the NEVA™-system was performed. Results: At 3 month follow-up 77 out of 96 patients (80.21%) reported to have erections sufficient for vaginal insertion without the use of any drug or additional device. Four (4.17%) patients did not report any improvement. Follow up with color Doppler ultrasound revealed a new or persistent venous leakage in 8 (8.33%) of the patients. No serious complications occurred. Conclusions: Our new pelvic venoablation technique using aethoxysclerol in air-block technique was effective, minimally invasive, and cost-effective. All patients were able to perform sexual intercourse without the previously used dosage of PDE5 inhibitor. This new method may help in patients with contra-indications against PDE5 inhibitors, in patients who cannot afford the frequent usage of expensive oral medication or those who do not fully respond to PDE5-inhibitors.

Method: A sample size of 40 kidney allograft recipients undergoing color Doppler Ultrasonography evaluation included in the study. Result: Corticomeduallry differentiation of kidney allografts within 24 hours post transplant period: There was no significant difference between CMD of kidney allorgrafts with complication and kidney allografts without any complication within 24 hour because the standard deviations of both groups were 0. Corticomeduallry differentiation in all kidney allografts, all were shows maintained corticomedullary differentiation. Conclusion: This study is aimed to assessing the role of CDUS in kidney allograft recipients to evaluate the graft perfusion immediate after anastamosis, within 24 hours and follow up period after engraftment of kidney allograft. Analyse the Color Doppler Ultrasound (CDUS) indices changes in parenchymal, and vascular cause of allograft dysfunction at follow up periods, to evaluate the uroloical, surgical and vascular complications in kidney recipients by using gray scale and color Doppler US at follow up periods and compare the results with biochemical parameter (serum creatinine). Immediate Doppler ultrasound is highly useful in the diagnosis of primary graft dysfunction and in follow-up of the transplanted patient.
