315 patients with average ages of 69.75 +/- 6.32 operated as method of Hryntschk in the department of urology of this hospital have shown that the major type of the benign prostatic hypertrophic adenoma was adenofibroma. The fibrous component accounted for high rate, therefore the adenoma usually was small and solid and able to cause the obstruction. The rate of adenoma of median of prostate was 21.5%. This is major cause of the urinary difficulty. The weight of the benign prostatic hypertrofic adenoma was direct proportional with the increased age but was not close correlated with the risk of the acute urinary difficulty.

This study involved 307 patients with benign hypertrophic prostate (BHP) who were underwent tumor removing surgically using Hryntschak’s method from January 1995 to June 1999 at the Military Central Hospital 108. Age of participants ranged from 50 to 89 years. The results showed that the older the patient was, the more severe the BHP-related urinary problems are and the poorer the post-operative recovery is. Post-operative monitoring and evaluation of result of operation for BHP need to be performed at lest 3 months post-operation, as manifestations of urinary disorders were stable. At 3-month postoperation, 98/144 patients (68.1%) have good outcomes, 45/144 (31.2%) have moderate and 1/144 (0.7%) have poor outcomes.

Lycopen - a carotenoid extracted from tomato had antioxidant effect stronger than other carotenoids, lowered the risk of cancer, especially prostate cancer/arteriosclerosis and delayed the development of prostate cancer. When heating tomato into viscous mixture, biological efficacy of lycopen is stronger than raw tomato or tomato juice. This efficacy is stronger when using lycopen combined with some carotenoids such as vitamin E and beta-carotene

This study was carried out on 131 patients (101 women and 30 men) with surgery for thyroid cancer at University Hospital No 103 from 1995 though March 2002. 49 patients (37.4%) were operated for the thyroid pathology before hospital admission. Based on clinical examination and laboratory measurements, the authors found that the rate of thyroid cancer was 1-2% of all cancers. The rate of papillary thyroid carcinoma (PTC) was 62.6%, follicular (FTC): 19.8% medullary (MTC): 5.3%, squamous (STC): 2.3%, and nondifferentiated (NDTC) tumors: 9.9%. All surgical procedures were performed according to principal rules of oncologic surgery. 12 sternotomy and 5 tracheotomy during operation were performed. Accidental injuries of the esophagus (2 cases) and the trachea (3 cases) occur during the resection of tumor. After the surgical resection, the chemotherapy, radiotherapy, hormone therapy have been used in various combinations, one patient died and all survivors have been followed up

Infertility is defined as lack of conception after at list 12 months of unprotected intercourse. For investigating and diagnosing infertile couples, semen analysis is necessary. Find out the reason of infertility is an important thing we need to do. In order to investigate harmful effects of some environmental factors, we have carried out this study. 466 semen samples in 420 male partners were analyzed basing on their jobs, we found that high ratio of azoospermia had been found in male partners who used to contact with high temperature. Low ratio of living spermatozoid had been found in male partners who used to contact with chemical substances and in the functionaries

Study on 50 patients (male: 12, female: 38), between the ages of 72 and 40, with hypertension (62% of patients), obesity (60%) in which abdominal obesity (78%) was carried out in Bach Mai Hospital during July 2000- March 2001. The results found that the lipemia disorder frequently occurred in patients with reduced glucose toleration according to the classification of Fredrichson (type IV). 69% patients with the reduced glucose toleration had a lipemia disorder accompanying with hypertension. The risk of hypertension among these patients was higher 6.7 times than this among patients without the lipemia disorder. 93% patients with the reduced glucose toleration and obesity had a lipemia disorder. This rate in the patients with abnormal obesity was 97%; 100% of patients with the reduced glucose toleration had signs of coronary insufficiency

The authors report a histological study of chronic gastritis. Results are as follows: Chronic gastritis showed high rate of chronic atrophic gastritis (76.1%), among them mild atrophic gastritis is 60%, moderate and severe atrophic gastritis is 15% and 1.1%, respectively. The majority of gastritis is in active chronic gastritis patterns (75%); H. pylori infection rate is 52.1%. Intestinal metaplasia was detected in 31.8%. The rate of complete intestinal metaplasia is higher than that of incomplete intestinal metaplasia (63.3% vs. 36.3%). Dysplasia was revealed in 7.9% (low grade: 77.3%; high grade: 22.7%. There is a significant correlation between atrophic levels and the rate of metaplasia and dysplasia.

Nowdays in Vietnam, Fuji-One and Monitor are organophosphorus pesticides widely used in agriculture. In order to investigate chromosomal mutagenic effects of Fuji-One and Monitor, we have carried out this study in mice. 4 group of mice were analyzed: Negative control group: 16 male mice were non-exposed to pesticides. Positive control group: 15 male mice were injected into the peritoneum with cyclophosphamide, which is a kind of mutagen. Fuji-One group: 5 male mice were injected into the peritoneum with Monitor. Analyzing of frequencies of chromosomal aberration in bone marrow cells and testicular cells of mice, we found that: (1) Monitor can cause chromosomal mutagenic effects in the bone marrow cells. (2) Fuji-One can cause chromosomal structural and numerical aberration. (3) The rate of chromosomal aberration in Fuji-One group was lower than those in positive control group but they were higher than those in monitor group

The best way for development of urological profession in the first decades of 21st century is to closely collaborate between researchers and clinicians in finding the solutions and new methods of treatment. The first step is to evaluate the basic available conditions and knowledge. From which to introduce the ways for changing and developing the urological profession.

Nowadays, there is high rate of infertile couples in population. For improving living quality, therefore some one has to take care of these couples. Infertility is defined as lack of conception after at list 12 months of unprotected intercourse. For investigating and diagnosing infertile couples, semen analysis is necessary. 446 semen samples in 420 male partners were analyzed we found that in infertile couples, 56% male partners had semen abnormality low motility 31.9%, oligospermia 16.43%, low viability 25.5%, teratozoospermia 14.05%, azoospermia 10.24%.
