Victims of war. Surgical principles must not be forgotten (again)!

Severe injuries to the limbs are common in wars and natural disasters, and most of them occur in developing countries with weak health-care systems. The International Committee of the Red Cross (ICRC) has gained a vast amount of experience in treating the war-wounded in this context. Basic principles for wound management, safe and simple methods for fracture-holding and amputation techniques adapted to missile and explosive injuries have proven successful. More than 81,000 amputees have been fitted with artificial limbs in ICRC workshops since 1979, but the needs are far greater. In an attempt to limit the effects of war, the ICRC promotes compliance with international humanitarian law, supports preventive activities such as the campaign to ban anti-personnel landmines, and strives to raise awareness of the implications of fast-developing weapon technologies.

Ultrasonography in complications of renal transplantation.

The reliability of ultrasonography in detecting complications of renal transplantation was investigated by reviewing the ultrasound examination on 78 renal transplants. The results of the ultrasound examinations were correlated with all available clinical, laboratory, radiographic, scintigraphic, and histopathologic data. With the exception of one urine leak no extrarenal complications of clinical significance, such as hydronephrosis, urine leak, lymphocele or hematoma were overlooked at ultrasonography. The exact nature of fluid collections was, however, only seldom accurately assessed unless fine needle biopsy was used. The accuracy in detecting both acute and chronic rejection was high with ultrasonography and a normal ultrasonography of a non-functioning kidney was a strong indication of acute tubular necrosis. Ultrasonography was very sensitive in detecting early acute rejection but was of less value in diagnosing repeated acute rejections with short intervals and in monitoring the response of treatment as the sonographic changes of rejection disappeared slowly.

Computed tomography in the diagnosis of complications following renal allograft surgery.

Computed tomography was used in a consecutive series of 74 transplantations in the diagnosis of complications to renal allograft surgery. Thirty-nine peritransplant fluid collections were demonstrated, 13 of these were subjected to surgery. A diagnosis of the specific nature of the fluid collection was possible in cases of urine leakage and fresh hematomas. The method was sensitive in defining the size of the renal pelvis though differentiation between postrenal obstruction and large non-obstructed collecting system was not always possible. The cause of postrenal obstruction could be identified in 5 patients out of 10. Renal infarctions were diagnosed in 8 patients. Computed tomography seems to be a highly accurate method in the diagnosis of complications to renal allograft surgery. The method can be used independent of transplant function and the use of contrast medium is necessary only to verify urine leakage and infarction.

[Functional control of the renal transplant via sequential computerized tomography. First results (author's transl)].

The enhancement of cortex medulla and arteria iliaca can be visualized separately, evaluated densitometrically and represented graphically by means of sequential computerized tomography of the renal transplant following intravenous contrast medium bolus injection. Since this enhancement performance is mainly dependent on perfusion, it is possible to determine the perfusion value of individual measurement areas. For example, a cortical defective perfusion, as is known in rejection, becomes evident as a flattening-out of the initial rise of cortex enhancement and can be distinguished from the largely normal type of curve obtained in acute tubular necrosis (ATN). The angiographically known prolonged "wash-out time' in rejection corresponds to a long-lasting corticomedullary density gradient. Despite restricted informative value because of the relatively small number of patients, it appears that sequential computerized tomography enables differentiation of postoperative anuria.

Evaluation of transplanted kidneys with computed tomography and ultrasound.

165 computed tomography (CT) and 98 ultrasound (US) examinations were performed in 64 renal transplant patients. The correlations between CT/US, contemporary clinical and retrospective diagnoses were analysed. CT and US are of great help in the post transplantation follow up, particulary when used together. Determination of the cause for unsatisfactory transplant function had always constituted one of the major problems for the clinician involved in the care for organ transplant patients. Traditionally transplant malfunction had been investigated by clinical examination, renography, radionuclearscanning, angiography and needle biopsy. (Nilsson et al. 1968. Starzl et al. 1970. Häyrö 1981). Computed tomography (CT) and ultra sound scanning (US) show promising capacities to differentiate between the alternative causes for diminished transplant function. (Frick et al. 1981, Smith 1981). The purpose of this presentation is to evaluate CT and US in the diagnosis of the various conditions causing impaired function of the transplanted kidney.
