Background: Renal transplantation could be considered for patients with end-stage renal disease. Ultrasonography is the imaging method chosen for renal allograft evaluation early in the postoperative period. Sono-elastography is used to estimate tissue stiffness. This study aimed to assess the correlation between sono-elastography and renal allograft histopathology in patients who had transplanted kidney and determine the efficacy of grayscale ultrasound, sonoelastography, and color duplex in evaluation renal allograft complications and correlation with renal function. Results: Forty patients (26 males and 14 females) who underwent renal transplantation were included. Their ages ranging from 10:52 years; they all subjected to ultrasound, color Doppler, sono-elastography, and histopathology. The studded patients were divided into 3 groups according to histopathology: patient with normal results, patients with ATI, and patients with CAI. The difference between the mean elasticity values between the three groups was statistically highly significant (p value < 0.001) with high specificity, sensitivity, and accuracy in differentiating ATI and normal groups and also CAI and normal groups, while the lowest sensitivity noticed in differentiating between ATI and CAI groups that is mean elasticity was good to differentiating between ATI and normal groups and also between CAI and normal groups while it was less in differentiating between ATI and CAI groups. As regards the RI, the highest sensitivity of the RI was in differentiating ATI and normal with high sensitivity, specificity, and accuracy, and the lowest sensitivity, specificity, and accuracy of RI were in differentiating CAI and normal groups. Conclusion: Transplanted renal allograft could be assessed by combined US, color duplex Doppler, and sonoelastography examination; also we can detect posttransplant complications early. Sono-elastography could be an efficient noninvasive method to diagnose and monitor kidney allograft rejection and follow-up of the renal allograft, which may give a further and possibly earlier prognostic index for chronic dysfunction in addition to serum creatinine.

Objective: To study the mandatory indications and accuracy of magnetic resonance (MR) imaging for the diagnosis of uterovaginal lesions associated with female infertility. Design: Prospective cross sectional study. Main outcome measures: Indications and accuracy of MR imaging for the diagnosis of uterovaginal lesions.Materials and methods: 423 infertile women were investigated by hysterosalpingography (HSG) and transvaginal ultrasonography (TVUS).In 54 women having uterovaginal lesions and 76 women with tubo-ovarian lesions, the diagnosis was not conclusive by HSG and TVUS and consequently they were examined by MR imaging. The present study was devoted for infertile women suffering from uterovaginal lesions.Results: MR imaging confirmed the diagnosis of agenesis of the uterus and the vagina (1 case), unicornuate uterus (2 cases, functioning rudimentary horn connected to the dominant horn in 1 case), uterus didelphys (1 case), bicornuate uterus (5 cases), septate and subseptate uteri (10 cases). Eighteen patients had multiple corporeal leiomyomas, 8 subserous and 10 intramural, diffuse adenomyosis, 14 cases and localized adenomyoma, 3 cases. Intramural leiomyomas showed enhancement on T2-weighted imaging suggesting a good response to uterine artery embolization (UAE).
