[Kidney lipomatosis in a transplantation donor].

OBJECTIVES: The aim of this clinical note is to report one case of incidental superficial renal mass during an organ explantation. METHODS: The renal donor was a 56-years-old male patient death for subaracnoidea haemorrhage without urological history. RESULTS: The anatomopathologic intraoperative study of the renal masses informed about the fatty nature of the tissue, and the renal implantation was performed. CONCLUSIONS: The find of a superficial renal mass during an organ explantatiation determine the necessity of a preoperative biopsy.

[Non obstructive retrocaval ureter].

We report a case on circumcavum ureter without obstruction or type two, according the Batenson and Atkinson's classification, in a forty-nine year old man. It was diagnosticated for a gross haematuria and renoureteral pain, because of a simultaneous urinary tract infection. We emphasize its absence of the typical morphology and obstruction signs. After twelve months the patient is still asymptomatic, without any medical or surgical treatment.

[Testicular and paratesticular prepuberal tumors: our experience and update on the topic].

OBJECTIVES: To evaluate the importance of testicular and paratesticular prepubertal tumors in our center and to make an update on the topic. METHODS AND PATIENTS: Data from all patients diagnosed of testicular and paratesticular prepubertal tumors and treated in our pediatric oncology unit from January 1st 1998 to December 31st 2003 have been revised. RESULTS: Seven cases are reported among one hundred and ninety patients (represents 3,68 percent of all treated tumors): five tumors affecting the testis and two cases of paratesticular tumors. Pathology classification was as follows: one yolk sack tumor, one mature teratoma, two nongerminomatous testicular tumors (one Sertoli cell tumor and one unclassifiable), one Burkitt's lymphoma and two paratesticular rhabdomyosarcomas. Primary approach was inguinal radical orchiectomy in all cases except neoadjuvant chemotherapy in the case of lymphoma and partial escrotectomy in one patient previously managed with transcrotal orchiectomy. Rhabdomyosarcoma cases received adjuvant chemotherapy. All patients are alive and well after a follow-up period ranging from 17 to 74 months. CONCLUSIONS: Testicular and paratesticular prepubertal tumors are rare. Except for one patient affected of lymphoma, surgical primary approach have been essential for treatment. The prognoses in this series has been excellent.

[Oral tegafur plus mitomycin versus intravesical mitomycin alone in the prevention of recurrence in stage Ta bladder tumors].

OBJECTIVE: The aim of this study is to know if the use of oral Tegafur associated to intravesical mitomycin is effective in the prevention of the relapses of Ta bladder tumors. METHOD: This is a prospective study in which we compare the recurrence rate and the disease-free interval of 2 groups of 40 patients each one, the first of them treated after the TUR with oral Tegafur and intravesical mitomycin, and the second with intravesical mitomycin alone. Tolerance of Tegafur was also studied. RESULTS: The group of the Tegafur presented a descent of the relapse rate and a continuation of the time free of illness; but it was not statistically significant. The tolerance to the drug was good, without important adverse effects. CONCLUSIONS: Tegafur seems an useful drug in the prevention of the recurrence of superficial bladder tumors, although it will be necessary bigger studies to reach statistically valid conclusions.
