ABSTRACT

OBJECTIVE: To evaluate the clinical efficiency of alpha1-adrenergic antagonists on stentless ureteroscopic lithotripsy treating uncomplicated lower ureteral stones. MATERIALS AND METHODS: From January 2007 to January 2013, 84 patients who have uncomplicated lower ureteral stones treated by ureteroscopic intracorporeal lithotripsy with the holmium laser were analyzed. The patients were divided into two groups, group A (44 patients received indwelled double-J stents) and group B (40 patients were treated by alpha1-adrenergic antagonists without stents). All cases of group B were treated with alpha1 blocker for 1 week. RESULTS: The mean operative time of group A was significantly longer than group B. The incidences of hematuria, flank/abdominal pain, frequency/urgency after surgery were statistically different between both groups. The stone-free rate of each group was 100%. CONCLUSIONS: The effect of alpha1-adrenergic antagonists is more significant than indwelling stent after ureteroscopic lithotripsy in treating uncomplicated lower ureteral stones.

ABSTRACT

PURPOSE: To evaluate the clinical value of computed tomography angiography (CTA) in reducing the risk of hemorrhage associated with mini-percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: A total of 158 patients with renal or ureter stones who had undergone mini-percutaneous nephrolithotomy were retrospectively enrolled into this study from May of 2011 to April of 2014. Group 1 (65 patients) underwent computed tomography angiography, and Group 2 (93 patients) underwent non-contrast CT. The clinical characteristics of the patients and hemorrhagic complications were recorded. The hematologic complications (transfusion rate, and preoperative and postoperative hemoglobin values) were assessed. RESULTS: There were no statistically significant differences in age, body mass index(BMI), stone diameter, operative time, stone-free rate, and hospital stay between the 2 groups. In group 2, 1 patient (1.1%) developed a renal arteriovenous fistula and was treated with embolus therapy. In addition, Group 2 showed significantly drop in hemoglobin (3.6 g/dL vs. 2.4 g/dL, respectively; P < 0.001) and more transfusions (9.7% vs. 1.5%, respectively; P < 0.05) compared with Group 1. CONCLUSION: The study showed that patients who underwent computed tomography angiography prior to percutaneous nephrolithotomy had lower drop of hemoglobin and needed less transfusions. These findings may suggest that the use of computed tomography angiography may reduce the risk of bleeding during percutaneous nephrolithotomy.

ABSTRACT

OBJECTIVE: Extracellular matrix metalloproteinase inducer (EMMPRIN) is a glycosylated member of the immunoglobulin superfamily whose function in human seminomas is unknown. We have recently determined that EMMPRIN possesses the ability to stimulate fibroblast and endothelial cell matrix metalloproteinase production, and that its expression was frequently up-regulated in several tumours of the urinary system. Thus, EMMPRIN expression might be associated with the progression of human seminomas. The aim of this study was to investigate whether the presence of EMMPRIN in seminoma tissues might help to predict the patients' prognosis. METHODS: Paraffin-embedded tissues from 65 patients with seminomas and 20 normal testes were processed for immunohistochemical staining using a mouse monoclonal antibody generated against human EMMPRIN, as primary antibody, and a biotinylated goat-anti-mouse IgG, as secondary antibody. In addition, the correlation of EMMPRIN expression with clinicopathologic characteristics and patients' prognosis was also analysed. RESULTS: EMMPRIN was detected in cancerous tissues of 53 patients with seminoma, but not normal testes. Thirty- five patients showed weakly to moderately positive and 18 patients intensely positive expression. Moreover, positive EMMPRIN staining correlated significantly with various clinicopathological factors (increased TNM stage and higher histological differentiation type) as well as decreased tumour-specific survival (log-rank, p=0.02). In particular, EMMPRIN expression was an independent prognosticator as shown by Cox regression analysis (p<0.001). CONCLUSION: EMMPRIN expression in a primary tumour predicts an unfavourable prognosis in human seminoma, suggesting its crucial role in the progression of this tumour.
