THE RENAL TRACT 187 A Figure 7.27 A lymphocoele adjacent to the upper pole of a transplant kidney. Ultrasound monitored the gradual resolution of this collection. B Figure 7.26 (A) Transplant rejection: peri-infundibular thickening (arrows) is demonstrated and the renal parenchyma looks abnormally hyperechoic with increased corticomedullary differentiation. (B) The Doppler indices are raised in this rejecting kidney, with no EDF. Loss of corticomedullary differentiation is noted in the kidney. ● surgical laparoscopic marsupialization is the treatment of choice. Haematoma An immediate postoperative phenomenon which usually resolves spontaneously. If the haematoma is due to an anastomotic leak at the main artery or vein, it can compress the renal vein, causing thrombosis in rare cases. On ultrasound, the haematoma can appear hyperechoic and illdefined in the early stages. As it resolves and liquefies, the margins become more defined and the centre becomes anechoic. Hyperechoic blood clots and strands of fibrin may be seen within the haematoma. ● ● Urinoma This occurs as a result of an anastomotic leak in the ureter. Urinomas are uncommon, but may progress to urinary ascites. They occur early following the surgical procedure, unlike lymphocoeles. Abscess If any of the above fluid collections becomes infected, this leads to an abscess. Hyperechoic debris can be seen in the collection and this may be treated with percutaneous drainage. Vascular complications Vascular occlusion Colour and spectral Doppler are essential for the diagnosis of postoperative vascular complications. Non-perfusion may be total or lobar (Fig. 7.28). Focal areas of hypoperfusion may be due to oedema in focal infection, arteriovenous fistula or severing of an accessory artery during harvesting of the transplant or at the time of implantation. Total vascular occlusion is rare, but occurs early. Patients may be asymptomatic and non-perfusion of the transplant may be inadvertently seen on either a routine scan or isotope study. Graft nephrectomy is the most likely outcome. Conversely, the appearance of good renal perfusion throughout the kidney on colour or power Doppler does not necessarily indicate normal vascularity and severe
