Urothelial carcinoma transmission via kidney transplantation.

Transmission of urothelial carcinoma via solid organ transplant has never been reported in the literature to our knowledge. We report a case of transmission of this tumour to a kidney recipient. The donor was a 37-year-old woman, victim of a subarachnoid haemorrhage.

Renal cell carcinoma in renal transplant patients.

Objectives: To report our experience with renal cell carcinoma in patients with end-stage renal failure receiving dialysis at two institutions that perform a large number of transplantations. Renal cell carcinoma is more frequent in patients with end-stage renal failure treated with dialysis and in renal transplant patients than in the population at large.

Methods: We reviewed the case histories of 1375 consecutive patients who had transplanted kidneys functioning for more than 1 year.

Adrenocortical tumors: results of treatment and study of Weiss's score as a prognostic factor.

Purpose: The differential diagnosis between benign and malignant adrenal cortical tumors circumscribed to the gland is controversial. One hundred and seven patients with adrenal cortex tumors (excluding those with primary hyperaldosteronism) were studied to assess the 5-year survival rate of adults, children, patients stratified by pathological stage, and patients stratified according to Weiss's score of <3 or >3.

Methods: The patients were evaluated both clinically and biochemically.

Induction of spermatogenesis in azoospermic men after varicocele repair.

Background: The purpose of this study was to assess the treatment outcome after varicocele repair in azoospermic men and to correlate this outcome with the testicular histology patterns.

Methods: Medical records of 15 azoospermic men who underwent testis biopsy and microsurgical repair of clinical varicocele between July 1999 and November 2000 were reviewed. All patients had at least two semen analyses showing azoospermia taken before the surgery and two semen analyses post-operatively.
