Summary Objective: We aimed to evaluate the effectiveness early outcomes of PAE in treating BPH patients with acute urinary retention (AUR). Method and results: in this prospective study approved by the institutional review board, a signed informed consent was obtained. There were fourteen patients with AUR due to BPH from 07/2017 to 07/2018. The patients were successful removal of the bladder catheter after 1216 days. Post-intervention 3 months, average evaluation of IPSS, Qol, PSA (ng/ml) and PV (cm3 ) decreased 63,2%; 73,19%; 79,98; 29,97% (ultrasound) 31,75 (MRI); Qmax 11,46 (ml/s), PVR 55,58 (ml). Conclusion: PAE in patients with AUR due to BPH is safe and effective. Key word: bening prostatic hyperplasia (BPH), Prostatic Artery Embolization (PAE), Acute Urinary Retention (AUR).

Staging of the MRI 1.5T has Acc 95,7% Conclusion: Image 1.5T MRI on observable clarity T2WI, DWI before the injection and T1FS after the injection contract. 1.5T MRI has high value for staging Cervical cancer. MRI should be used routinely for staging Cervical cancer. Keyword: Cervical cancer, MRI of cervical, staging cervical cancer.

Clinical, subclinical, and Transrectal ultrasound in patients with hematospermia SUMMARY Purpose : Describe clinical features, subclinical and Transrectal ultrasound images in patients with hematospermia Material and Methods : This study included 85 male patients with hematospermia, had semen test and seminal microbiologic test, had Transrectal ultrasound (TRUS) at Viet Duc Hospital since August 2018 until April 2019. Results: The age of patients ranged from 16 to 66 years (x= 36,6±11,8years), patients 40 years old or older than and younger 40 were 36,5% (31 cases) and 63,5% (54 cases), the duration of symptoms was 1 day to 10 years (x= 3,5 months). In most cases hematospermia is painless (75,3%), or painful ejaculations (24,7%), color of the ejaculate: brownish (40%) and red (51,8%). Abnormalities were revealed by TRUS in patients (92,9%). The percentages of pathological conditions located in the seminal vesicles, in the ejaculatory ducts and in the prostate were 71,7% (61 cases), 76,4% (65 cases), 57% (47 cases), respectively. No patients had malignant tumor. Seminal microbiologic test are usually negative (71,9%), positive Streptococus (22,8%) and Enterococcus (5,3%) Conclusion : Our conclusion is that TRUS is a safe, non-invasive technique which can be used to detect lesions of the prostate, seminal vesicles and the ejaculatory ducts in patients with hematospermia Key words : Hematospermia; Transrectal Ultrasound (TRUS)

Role of computed tomography in diagnosing and staging of the renal cell carcinoma SUMMARY Background : Early diagnosis and accurate preoperative staging of the renal cell carcinoma are necessary to select the most appropriate treatment. Purposes : This study aims to describe the imaging characteristics and define the value of CT in preoperative staging of renal cell carcinoma. Subjecs and methods : Retro - and prospective cross section descriptive study of 105 patients in Binh Dan hospital from Dec 2012 to Apr 2015, with histologically verified renal cell carcinoma and using CT preoperatively. Imaging characteristics and staging were made by evaluating imaging obtained and compared with the operative and postoperative histopathologic results. Results : The most common location was upper 1/3 kidney (32.4%). Tumor size 41-70mm (52.4%) had the highest percentages. Tumors had constrast enhancement (100%), unsmooth margins (55.2%), intra-tumoral necrosis (91.0%), calcification (16.2%). Tumor detection in the nephrographic phase were 100%. Tumors had renal sinus fat invasion (34.3%), extension beyond Gerota’s fascia (17,1%); involvements of ipsilateral renal vein (6.7%), inferior vena cava above diaphragm (4,8%) and below diaphragm (5.7%), invasion of ipsilateral adrenal gland (1%), local lymph nodes (13.3%) and distant metastases (5.7%). Tumors had the surgical stages I, II, III, IV and then the mean tumor sizes increased 40.50mm, 63.60mm, 67.58mm, 97.01mm, respectively. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of CT to evaluate the perinephric fat invasion were 88.52%, 68.18%, 80.0%, 80.0%, 79.41%, respectively. Percentages of CT staging correlating with operative staging was 90%, in which stage I was 100%, stage IV was 91%. Conclusions : CT is still the principle basis for preoperative staging of renal cell carcinoma. Keywords : Computed tomography (CT), renal cell carcinoma.

The MSCT diagnostic values for bladder cancer SUMMARY: Bladder cancer is the most common malignant tumor of urinary tract. Most of them arise from transitional epithelium cells (98%), within 90% from transitional urothelia cells, 6% from squamous cells [1]. The gold standard to diagnosis bladder cancer is cystoscopy with biopsy. MDCT is recommended to assess tumor’s location and invasion. It is valuable in stage classification and management decision, especially for surgery. Purposes: “ Describe the MSCT imaging characteristics of bladder cancer” and “assess value of MSCT in diagnosis bladder cancer”. Materials and methods: From 8/2013 to 8/2014, there are 92 consecutive patients with bladder cancer were undergone 64-slide- CT urography. All of them were undergone operation with pathology after surgery. Results: The sensitivity, specificity and accuracy for bladder cancer invasion detection were 89.6%; 81.1% and 85.9%. About tumor classification (T), the sensitivity of stage <T3a was 81.8%; the specificity was 89.6% and the accuracy was 85.9%. For Stage T3b, the sensitivity was 90.6%; the specificity was 96.7% and the accuracy was 94.5%. The sensitivity and specificity of stage T4 was high, especially were 100% in stage T4b. The detecting of lymphatic nodules in MDCT was quite good, with the sensitivity was 85.7%. The bigger lymphatic nodules were, the higher risk of malignancy was. Conclusion: MSCT is valuable in stage classification of bladder cancer. Key word: Bladder cancer, MSCT scanner.

Evaluating the results of prostatic arterial embolization for benign prostatic hyperplasia SUMMARY: Objective: To describe techniques and early outcomes of PAE in treating BPH patients. Method and results: from 12/2013 to 11/2014 performed 12 times PAE, average age = 67.1 (51-84), before-intervention average evaluation IPSS, Qol, Qmax (ml/s), PVR (ml), PSA (ng/ml), PV (cm3) are 26.6; 4.8; 8.86; 59; 4.95; 68.7 Post-intervention 3 months decreased 45.86%; 41.67%; 55.76%; 37.96%; 28.75%, 25.47%. Conclusion: PAE in BPH is safe and effective at the Radiology Department at Bach Mai Hospital. Keywords: prostatic arterial embolization, benign prostatic hyperplasia.
