Report of two cases of pheochromocytoma of the bladder to note its variable and misleading features. Pheochromocytoma of the bladder is a rare disease, that develops in the bladder from sympathetic plexus. This kind of tumor accounted for 10 to 15% of paragangliomas, 1% of pheochrocytomas and 0.1% of bladder tumors. This disease is more common at age 40 and in women than men (3/1). The diagnosis is based on biochemical tests and current imaging techniques, particularly ultrasonography and computerized tomography. Careful follow-up is mandatory because the tumors may progress to malignancy

Nowadays, scientists are focus on studying the hereditary basic of renal cancer in order to detect early renal cancer and initially apply some treatment methods at molecular level. There are 4 types of renal cancer: Firstly, clear cell renal carcinoma is the most common one. Secondly, hereditary papillary renal carcinoma type I (HPRC) generated from epithelium of distal convoluted tubules which was discovered by Zbar in 1944, often occurs after 40 year old. Thirdly, hereditary chromophobe renal carcinoma and oncocytome which were described by Thoenes in 1985 and by Zipell in 1942 respectively. Hereditary oncocytome was found by Weirich in 1998. Fourthly, hereditary leiomyomatosis renal cell carcinoma (HLRCC) and multiple cutaneous leiomyoma (MCL) belonging to papillary renal carcinoma type II is very malignant and metastatic

Cytomegalovirus always is risk of complication and mortality for patients with kidney transplantation. The timely, effective diagnosis and treatment is a leading responsibility while waiting for vaccine responding with this virus. The diagnosis of cytomegalovirus based on the detection of pieces of cytomegalovirus in the cell, viral culture and serum test. ELISA is common method to detect the IgG and IgM. The treatment involved the use of anti-viral agents such as ganciclovir, foscarnet...

From 6/1981 to 6/1996 a total of 978 consecutive patients (mean age: 69) presenting with bladder outlet obstructive were admitted to Viet Duc hospital for elective transurethral resection of prostate). The feagure of TURP were increasing from year to year and the TURP/ open surgery ratio was 80% in 1996. The procedures were performed with low mortality (0.3%) and low morbidity (bleeding 0.6%, capsular perforation (0.7%). TURP syndrome (0.3%), dysuria (1.8%) incontinence (1.1%), urethral stricture (1.5%) Hospital stay: 5(2 days. Overall outcome: good: 77%, moderate 19%; unsatis factory: 4%.

Genetic factor is considered a special risk in prostate cancer. This article introduced some investigations of genes in prostate cancer. Genetic mechanisms in this disease may be complicated and diversified due to mutations or minor variations but major impact. It is shown current attitude of clinicians for hereditary prostate cancer

As clinical study showed that COX-2 is strengthened in the angiogenesis, apoptosis, invasive and increasing immunization in the process of tumor progress. The first result of use inhibitor COX-2 has potential in prevention and treatment of tumor. Use COX-2 in progress of prostate cancer as metastasis tumor and be low isolated. Use COX-2 in bladder tumor without response with BCG and after cut off bladder. Use COX-2 in metastasis kidney tumor or have high risk in Von Hippel-Lindau

Prostate cancer is the most common detected cancer and the second cause of mortality in male patient aged > 45 in many countries in the world. New advances in molecular biology and genetics in association with great achievements in biological technology permit identily the creation and the process of prostate cancer in various profiles. The role of inflammation in the onset of prostate cancer is opened slightly. Research permits to predict new markers and to make promises for new treatments efficacy progressively against this dangerous disease of increasing concern

Between 1/1994 and 12/2000, 52 patients with 53 adrenal tumors were operated in the Department of Urology - Viet Duc Hospital. Through subcostal approach, the initial control of the main adrenal veins and arteries was performed in 84.6% cases (71% in the right and 100% in the left adrenal tumors). Hemodynamic is maintained at the first day of postoperative period (88.5%). The outcome was good in 96.2% of cases, exception for one death at the third postoperative day by acute adrenal failure and another from prolonged hypertension. No early hemorrhage was observed in the postoperative period. Improved surgical outcomes have been the result of advances in localization techniques, preoperative medical management and anesthetic practice.

Currently, the telomerase is being considered as a marker of cancer because 90% of cancer cells in human have positive telomerase. The telomarase used to early diagnose, monitor and predict after the treatment. In addition to, telomerase also is objective of many researches to treat the cancer. It had better combine the anti telomerase and chemotherapy

Telomerase is a ribonucleoprotein enzyme. Which is responsible for catalyst for increasing chains of telomere and limitation of shortening the chromosome terminal head. Telomerase has activity for the primary cells but inhibited differentiate cells. Telomerase was considered most significantly as a marker of cancer because 90% of cancer cells in human had positive telomerase. The telomerase was used to early diagnose and monitor as well as predict outcome. The antitelomerase therapy was a proper method to prevent relapsed cancer after the traditional treatments
