A 20-year experience in cadaveric pediatric en bloc kidney transplantation in adult recipients.

BACKGROUND AND OBJECTIVES: En bloc kidney transplantation (EBKT) from pediatric donors into adult recipients increases the donor pool. However, this surgical procedure is not widely performed in many transplant centers. To evaluate the long-term outcomes of EBKT from pediatric donors into adult recipients in a single center. MATERIAL AND METHODS: Retrospective analysis of 42 patients who received pediatric cadaveric EBKT in our center since 1999. Median follow-up period was 73 months (5-233) in which renal function tests were taken and complications registered. RESULTS: We have performed 42 EBKT from pediatric donors into adult recipients in our center. The recipients' age was 44.1 ± 11.8 years. Pediatric donors were 22.4 ± 14.7 months old and weighted 11.3 ± 3.6 kg. Cold ischemia time was 15.7 ± 4.5 h. During a median follow-up of 73 months, 35 patients (83.3%) had graft survival with excellent function (first-year serum creatinine levels of 0.99 ± 0.25 mg/dl). There were seven graft losses (16.7%) in the immediate postoperative period (four cases of vascular thrombosis, one anastomosis dehiscence and two cortical necrosis). CONCLUSIONS: The pediatric en bloc renal graft transplantation into adults is a safe technique with excellent medium- to long-term functional performance. The vast majority of significant complications leading to graft loss were reported in the immediate postoperative period. A good selection of donors and recipients as well as an adequate surgical technique are essential to minimize the occurrence of adverse events.

[Value of transrectal FNA in the diagnosis of prostate cancer in elderly patients]. / Valor de la PAAF transrectal en el diagnóstico del cáncer de próstata en pacientes de edad avanzada.

OBJECTIVES: To identify if there is a group elderly patients with clinical suspicion of prostate cancer in which pathological confirmation may be unnecessary, and if prostatic transrectal fine needle aspiration (FNA) may be a useful diagnostic tool for old patients. MATERIAL AND METHODS: A total of 72 patients aged 75-93 years were evaluated by means of prostatic transrectal FNA. Antibiotic prophylaxis, analgesia or cessation of anticoagulant therapy were not necessary. RESULTS: In 35 patients (48.6%) cytological diagnosis was positive for prostatic adenocarcinoma, whereas in 37 cytology was negative for cancer. In 100% of patients with PSA > 30 ng/ml or with PSA > 20 ng/ml and suspicious digital rectal examination FNA results were positive for cancer. 4.1% minor and 1.3% major (acute prostatitis) complications after FNA were observed. CONCLUSIONS: In male patients older than 75 years with PSA > 30 ng/ml or with PSA > 20 ng/ml and suspicious digital rectal examination, histological confirmation of carcinoma by prostatic biopsy may be not necessary, because of the high probability of a positive result. When histological confirmation of prostatic carcinoma is required in elderly patients, transrectal prostatic FNA is a valid alternative to transrectal biopsy, due to its excellent tolerance and low complication rate.

[Bilateral testicular cancer: a report of four cases]. / Cancer testicular bilateral: presentación de cuatro casos.

Bilateral testicular cancer represents from 2 to 5% of all testicle tumors, even though this prevalence nowadays is increasing. The median age of presentation was from 15 to years and in approximately 75% of them occurred metachronously. There used to be concordance in histological findings between both testicles, being seminoma the most common histological type. The most important risk factor in the development of testicular cancer is the presence of intratubular germ cell neoplasia. Radical orquiectomy is the treatment to choose, although in some carefully selected patients testis-sparing surgery may be considered. We present four cases attended in our medical service, we analize the risk factors, management of tumors and a medical literature review is done.
