AbstractAbstract
[en] Background: Magnetic resonance urethrography (MRU) can be used for depicting not only anterior urethral strictures but also periurethral anatomy in order to produce a management plan. Purpose: To determine if thick slab single-shot fast spin echo (SSFSE) MRU is useful for evaluating anterior urethral stricture compared to fast recovery fast spin echo (FRFSE) MRU. Material and Methods: Ten patients with benign anterior urethral stricture underwent both thick slab SSFSE MRU and FRFSE MRU using sterile jelly for urethral distension before retrograde urethrography. The glans penis was tied at the time of MRU. The two types of MR image were compared regarding stricture length, scan time, and image quality. We also determined whether or not both of the two MR sequences could display an entire anterior urethra on one image. Results: The stricture length on thick slab SSFSE and FRFSE MRU ranged from 4.0 to 71.3 mm (36.4 21.8 mm) and from 4.0 to 67.5 mm (35.7 20.8 mm), respectively (P > 0.05). The mean scan time for thick slab SSFSE and FRFSE sequences was 2 s and 194 s, respectively (P < 0.05). However, regarding image quality, thick slab SSFSE MRU was inferior to FRFSE MRU (P < 0.05). All the thick slab SSFSE MRU displayed the entire anterior urethra on one image, while only five FRFSE MRU did so (P < 0.05). Conclusion: Thick slab SSFSE MRU can provide a concordant stricture length when compared to the FRFSE MRU and imaging of the entire length of the anterior urethral stricture with subjective reduced image quality and scan time.

AbstractAbstract
[en] The peripheral cutting balloon has been used to treat various nonvascular strictures as well as vascular stenosis. In this article, we describe for the first time the use of the cutting balloon in the treatment of patients with urethral stricture. Four patients with bulbar urethral stricture were included in the study. All strictures were successfully dilated with the cutting balloon, and patients were free of symptoms at 6-month follow-up. Cutting-balloon dilatation is a safe, easy-to-perform, and effective treatment for patients with tight urethral strictures.

AbstractAbstract
[en] Congenital urethral valve is the common cause of hydronephrosis in newborn infants and the most common cause of bladder outlet obstruction in male children. We reviewed and analysed radiological findings and associated anomalies of 16 cases of congenital urethral valve which were examined during the period from January 1985 to December 1989. The most frequent age was under one year old (56%). The main symptoms were urinary dribbing (37.5%), weak stream (25%) and urinary frequency and incontinence (25%). Anterior urethral valve (AUV) was 5 cases (31%) and posterior urethral valve (PUV) was 11 cases(69%), in which 10 cases were Type I and one case was Type III. Bladder wall thickening was seen in all cases and its severity was partly correlated with the degree of vesicoureteral reflux (VUR). VUR was observed in 12 cases (75%), and relatively severe in older age group. The degree of VUR was milder in AUV than PUV. Hydronephrosis was more severe in PUV than in anterior one, and its degree was correlated with the severity of VUR. Associated anomalies were ectopic urethral opening (2 cases), PDA (1 case), congenital megacolon (1 case) and patent urachus (1 case) in PUV. So early diagnosis and treatment of congenital urethral valve is essential to the prevention of renal damage

[en] Renal duplication with obstruction due to various intrinsic or extrinsic factors has been described in several reports. Surprisingly, few reports are to be found concerning double collecting systems obstructed by calculi. Two cases of renal duplication with obstruction due to stones are described. The potential risk of misdiagnosis is emphasized. 16 refs.; 4 figs

AbstractAbstract
[en] Authors present an overview of genitourinary tuberculosis in terms of epidemiology, clinical signs, diagnostic procedures including various imaging modalities, therapy and prognosis. The hopes that tuberculosis (including urogenitary tuberculosis) in our regions would be eradicated were not fulfilled and we need to consider this diagnosis because the prognosis depends on the adequate and timely treatment.

AbstractAbstract
[en] Background: Although CT urography (CTU) is widely used for the evaluation of the entire urinary tract, the most important drawback is the radiation exposure. Purpose: To evaluate the effect of a noise reduction filter (NRF) using a phantom and to quantitatively and qualitatively compare excretory phase (EP) images using a low noise index (NI) with those using a high NI and postprocessing NRF (pNRF). Material and Methods: Each NI value was defined for a slice thickness of 5 mm, and reconstructed images with a slice thickness of 1.25 mm were assessed. Sixty patients who were at high risk of developing bladder tumors (BT) were divided into two groups according to whether their EP images were obtained using an NI of 9.88 (29 patients; group A) or an NI of 20 and pNRF (31 patients; group B). The CT dose index volume (CTDIvol) and the contrast-to-noise ratio (CNR) of the bladder with respect to the anterior pelvic fat were compared in both groups. Qualitative assessment of the urinary bladder for image noise, sharpness, streak artifacts, homogeneity, and the conspicuity of polypoid or sessile-shaped BTs with a short-axis diameter greater than 10 mm was performed using a 3-point scale. Results: The phantom study showed noise reduction of approximately 40% and 76% dose reduction between group A and group B. CTDIvol demonstrated a 73% reduction in group B (4.6 ± 1.1 mGy) compared with group A (16.9 ± 3.4 mGy). The CNR value was not significantly different (P = 0.60) between group A (16.1 ± 5.1) and group B (16.6 ± 7.6). Although group A was superior (P < 0.01) to group B with regard to image noise, other qualitative analyses did not show significant differences. Conclusion: EP images using a high NI and pNRF were quantitatively and qualitatively comparable to those using a low NI, except with regard to image noise

AbstractAbstract
[en] To evaluate the safety and effectiveness of the combined photoselective vaporization of the prostate (PVP) and bipolar transurethral resection of the prostate (TURP) in high-risk symptomatic patients with large prostates. Between January 2007 and January 2010, a prospective study was performed in Shandong Provincial Hospital, Shandong University, Jinan, Shandong Province, China. One hundred and one patients presenting with various kinds of systematic diseases, and with an American Society of Anesthesiologists score of 3 or greater underwent PVP plus bipolar TURP for severe lower urinary tract symptoms due to benign prostatic hyperplasia with prostatic volume greater than 80 ml. The International Prostate Symptom Score (IPSS) and quality-of-life questionnaire (IPPS-QoL), maximum flow rates (Qmax), postvoid urine residues (PVR), and MRI prostatic volumes were recorded. Perioperative data, functional outcome, and complications were evaluated. Patients were reassessed at 3, 6, and 12 months. The mean operation time was 68.5 +/- 23.9 minutes. The mean pre- and post- operative prostate volumes were 102.2+/-33.1 ml and 40.4+/-15.6 ml. No severe complications were observed. Significant differences in IPSS, Qmax, and PVR values were recorded within the follow-up period. The results of our study show that PVP plus bipolar TURP have an excellent efficiency and low morbidity in high-risk patients with large prostates (Author).
