Primary grade 1 transitional cell XXXX .

@entity1 @entity5 @entity150 @entity811 @entity703
During a 22-year period 224 @entity1 were seen for treatment of transitional cell @entity703 . Of these @entity1 49 (22 per cent) had grade 1 lesions. Followup ranged from 5 to 25 years. The most common symptom was @entity811 . In only 54 per cent of the 49 @entity1 was a filling defect noted on excretory urography. Forty-seven @entity1 (96 per cent) had stage I disease. Treatment included total nephroureterectomy, nephrectomy or segmental resection. In 11 @entity1 (23 per cent) evidence of @entity150 developed 8 months to 12 years (average 4 years) after the diagnosis of @entity5 of the upper urinary tract and 73 per cent of these recurrences were noted within the first 3 years. In 1 @entity1 a @entity5 developed in the opposite upper urinary tract. In only 1 of 15 @entity1 who had had partial ureterectomy or local excision @entity5 developed in the ipsilateral ureter. @entity1 survival time was identical to that in an age-matched control group. We conclude that the most significant findings are the subsequent high incidence (23 per cent) of @entity150 and the comparable survival in these pateints and in an age-matched control group. Furthermore, these results suggest that operations preserving the renal parenchyma, that is segmental resection, should be used more frequently.
