66 flaps including 6 controlled, were divided into two models, each includes 30 flaps and each model was divided into 5 groups, evaluated after 4, 8, 12, 16 and 20 days after implantation. From the random implantation of a isolated pedicle of artery or vena in an abdomen skin flap, new blood vessels occurred and connected with the existent system of vessels in the flap. After 20 days, new vascularity was established in both models, as the same in the control group. Blood supply was considered appropriate and the flap could be moved safely along the newly implanted pedicle

A study aimed to evaluate the antioxidant activity (AOA) of traditional medication by determining the iodine index of Tween 80 in tentative samples (with the extraction of traditional medication) and control samples (without the extraction of traditional medication). It should not apply the spectrometry to evaluate the AOA of these medication because of their complicated chemical components, especially chromatic compounds which interfere the photic density

Both benign and malignant tumors in adrenal glands could make hypersecretion syndrom arised. Benign tumor usually has small size, homogenous intensity on cross-section. Opening surgery to remove the adrenal gland remains a safe and effective operation. However, a well trained surgeons can remove the tumors by endoscopy. It is an invasive interference with a short term hospitalisation with very low rate of complications.

Fluorodeoxyglucose positron emission tomography (FDG-PET) has a limited role in the diagnosis of prostate cancer mainly because of the low uptake of FDG in the tumor. FDG-PET has shown some advantages in the assessment of lymph nodes and bone metastases. FDG-PET has a significant potential to assist with the diagnosis and management of testicular cancer. PET has been most useful in defining the presence or absence of disease in patients with residual masses. Role of PET in renal cell carcinoma and bladder cancer is so limited. Some new marked atoms have studied to increase effects of PET in diagnosis urologic malignancies

Report one case of a male patient, aged 32 years old, admitted hospital due to left sciatica for two years. Ultrasound studies discovered 3-degree left hydronephrosis due to left ureterolithiasis. The patient was extraperitoneal laparoscopic pelvic ureterolithotomy. Operation time was 130 minutes; blood loss was about 10ml. The patient refarted on the first day; drainage was pulled out on the second day and discharged on the third day after operation. He only used pain relief medication on the first postoperation day. After one week, the patient was reexamined to pull out ureteral catheter. The incision healed well. Extraperitoneal laparoscopic surgery was minimally invasive, so patient could feel comfortable in postoperative period was for s

The research was carried out on 108 stroke patients, 108 healthy control subjects matched in age and gender at the Hue Central Hospital in 2004. Results: Increasing the mean level of homocystein in blood is new risk factor of stroke. It’s maybe an independent risk factor or combining with other risk factors of stroke (especially hypertension). The rate of hyperhomocysteinemia is higher in patient group than in control group. There were statistically significant association between the mean blood homocystein level with amount risk factors of stroke (age, smoking, blood pressure, uremia, creatininemia, HCT, platelet). Especially, the mean homocystein level in blood had a negative correlation with Glasgow scores. Quantifying the homocystein level in blood of stroke patients can predict the severity of conscious impairment

Transrectal ultrasonography (TRUS) in prostate cancer could show the images of multiform prostate adenomas. Specific sign is a hypoechoic area in periphery of gland. Overall, sensitivity (32%) and specificity (51%) of TRUS in diagnosis prostate cancer weren’t high. The false negative was from 30% to 40%. Two major roles of TRUS were to determine suspected lesions and to increase accuracy of prostate biopsy. TRUS techniques in diagnosis prostate cancer were: conventional TRUS, TRUS with Doppler, TRUS with contrast Doppler, and TRUS with 3D ultrasound. Under TRUS-guiding, biopsy can be performed through perineum or rectum

Splenic abscess is a rare clinical condition, and treatment is difficult due to atypical clinical symptoms. Two patients with splenic abscess treated at HCMC University Medical Center from September 2002 to October 2004. Symptoms included fever and abdominal pain of the left upper quadrant. Ultrasonography as initial investigation in both cases, followed by CT scan in one, is necessary for the diagnosis. Splenectomy was the definitive therapeutic option with good results, and there was no complication and mortality

In the last 2 decades, the great progress of imagine techniques, endoscopic equipments and extracorporeal lithotripsy made a revolution in the treatment of urinary stones. Urinary stones now can be treated successfully by minimal invasive procedures. The means of urinary stones treatments consist of shock wave lithotripsy (SWL), percutaneous nephrostolithotomy (PCNL), ureteroscopy (URS), laparoscopy, retroperitoneal endoscopy, and laparotomy. The trends of urinary stones treatments include treating kidney stones (big or small stones), ureteral stones (in the upper third, medium third, and lower third of ureter)
