The incidence of malignant melanoma in the UK is still rising despite public health warnings about the risks of excessive sun exposure. This aggressive tumour can metastasize to virtually any organ, even years after resection of the primary lesion and cause a variety of radiological appearances. This review provides examples of both typical and non-specific imaging features of melanoma metastases, as well as examples of primary choroidal melanoma.
From January 1985 to July 1989, 36 children received a renal transplant at our hospital. Their ages ranged from 2 to 18 years. All patients had a standard neoureterocystostomy according to Lich-Grégoir. In the first 18 patients, no transanastomotic stent was placed. In the latter 18, a transanastomotic stent with or without suprapubic bladder drainage was performed. In the nonstented group, six severe urological complications occurred, two of which eventually resulted in loss of the transplant. In the stented group, only one severe urological complication occurred. No kidneys in this group were lost due to urological complications. The number of urinary tract infections in the nonstented group was the same as in the stented group.
