“…Recently, the need for kidney transplants has skyrocketed in Mexico and Latin America, mainly due to the increased prevalence of chronic and degenerative diseases. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] CENATRA´s records show a rise of 11% in kidney transplants from 2012 to 2017, 17 yet the Regional General Hospital No. 1 in Tijuana had a 12% decrease in transplants during this same time period.…”

“…Multiple studies have proven ultrasonography's (US) primary role in kidney transplant care, yet none have linked findings (other than complications) with organ rejection. [9][10][11][12] Thus, the present study sought to assess the morphological, arterial and pathological characteristics of transplanted kidneys through gray scale and color Doppler ultrasonography and to associate factors predicting transplant rejection.…”

“…Written consent was waived given that this is a retrospective study. With previous authorization by the Local Research Committee and hospital director, we reviewed each patient´s file and collected the following data: age, gender, type of donor, transplanted kidney characteristics (anatomical position, diameter, cortical echogenicity, corticomedullary differentiation, complications, and renal artery resistive index) [7][8][9][10][11][12][13] obtained via grey scale and Doppler US, and the absence/presence of renal rejection (and whether it was acute or chronic). 14 Ultrasounds were performed using a Philips (SONOS 45000 model) equipment, in conjunction with a 5 MHz linear transducer and a 2.5MHz convex transducer, using real time tracking in grey scale and color Doppler.…”

Standardowe badanie w prezentacji B oraz badanie z podaniem środka kontrastowego (US-CE) - porównanie przydatności badań ultrasonograficznych w ocenie echostruktury i wielkości krwiaków u pacjentów po przeszczepie nereki – wstępne doniesienia.

“…The most important problem in the routine examination in B presentation, used for post-operative diagnostics of transplanted kidneys, is the interpretation of images in time [19]. It is evident that haematomas rapidly evolve changing their echogenicity from protein-rich fluid into solid or solid-fluid structure.…”

“…It is evident that haematomas rapidly evolve changing their echogenicity from protein-rich fluid into solid or solid-fluid structure. Furthermore, haemolysis may transiently change the structure of haematoma [18,19]. These changes are accompanied by significant alterations in the echogenicity and ultrasonographic pattern of haematomas from low echo, typical for fluid-filled spaces, to solid (tissue-like) echogenicity and then again back to low echo for fluid-like pattern.…”
