[Computer tomography following renal tumour embolisation (author's transl)].

CT examination of eight patients after palliative embolisation of a malignant renal tumour showed a distinct reduction in renal size, beginning after a week and lasting for two or three months. In the patients who survived for more than six to twelve months, the tumor increased in size, as was shown by an increase of tumour volume and tumour revascularisation which could also be demonstrated by computer tomography. Gas in the tumour after embolisation was seen in four out of six cases within the first week and in another case it persisted for five months, without evidence of the presence of a renal abscess or urinary sepsis.

[The diagnosis and differential diagnosis of benign polyps of the ureter (author's transl)].

The radiological appearances of fibro-epithelial polyps of the ureter are demonstrated by four cases and the differential diagnosis is discussed. These mesenchymal tumors are characterised by their variable position and change in shape during the course of a retrograde pyelogram; they appear as smooth intraluminal filling defects with a narrow base and occasionally a racemose pattern. In general, they do not cause ureteric obstruction--and are more common on the left and in the proximal ureter.

[Bilateral breast cancer (author's transl)].

The frequency of bilateral primary (simultaneous and nonsimultaneous) breast cancer in 1420 patients was reported. The number of cases of bilateral breast cancer not caused by metastases amounted to 1,75%. The problems and significance of follow-up checks was discussed.

Surgical ligation vs. angiographic embolization of the vena spermatica: a prospective randomized study for the treatment of varicocele-related infertility.

Varicoceles as a common cause of male infertility are treated either by surgical ligation or, more recently, by angiographic occlusion of the spermatic vein. In the present prospective randomized study 38 patients were treated by surgical ligation and 33 by angiographic embolization. During the 12-month follow-up period a significant increase in sperm number (at 3 and 12 months) and sperm motility (at 12 months) occurred in both groups while sperm morphology remained unaffected. Altogether, 22 pregnancies (31%) were reported within the year following treatment, of which 11/38 (29%) occurred in the ligation group and 11/33 (33%) in the embolization group. Thus both treatment modalities appear equivalent, whereby embolization has the advantage that it can be performed on an outpatient basis.

Preoperative renal tumor embolization. A useful procedure?

The medical reports of 113 patients operated upon for renal tumors were retrospectively reviewed to assess the value of preoperative embolization. Coils or ethanol were used preoperatively in 55 patients while 58 patients underwent nephrectomy without embolization. The tumors were staged according to the TNM and the Robson staging classification. T1 and T2 tumors as well as T3 and T4 tumors were grouped together for statistical evaluation. There was no significant difference in intraoperative blood loss, operation time and survival rate between patients undergoing preoperative embolization and those who had only nephrectomy. Duration of hospital stay was always longer in the preoperatively embolized group. Preoperative embolization of renal tumors neither improved the patients' outcome nor reduced the surgical risk. Robson's classification, stage III/IV, did not show any significant differences for embolized patients or for those nephrectomized without embolization.
