[X-ray diagnosis of invasive thymoma]. / Zur Röntgendiagnostik invasiver Thymome.

Between January 1981 and September 1985, invasive thymomas were diagnosed in 13 patients attending the municipal hospital at Köln-Merheim. All these patients were examined radiologically and the tumour removed at thoracotomy, and irradiated in our Radiotherapy Clinic. Invasive thymomas appear as space-occupying lesions on chest radiographs taken in two planes, or on computed tomography. Infiltration by the thymoma in stages III and IV can be demonstrated by computed tomography.

[Experiences with a modified nephrostomy instrument kit in ultrasound-guided kidney fistulization]. / Erfahrungen mit einem modifizierten Nephrostomiebesteck bei ultraschallgeführter Nierenfistelung.

During a period of 24 months, ultrasound-guided percutaneous nephrostomies were performed in 51 patients in the Hospital at Köln-Merheim. The procedure was carried out with a modified nephrostomy instrument manufactured by Angiomed, Ettlingen, according to our own design. The procedure was successful in 49 patients. In one case it had to be abandoned because of lack of patient co-operation. In one patient a pyonephrosis was found and the patient was treated surgically.
