PURPOSE: Complications after prostate biopsy have increased and various causes have been reported. Growing evidence of increasing quinolone resistance is of particular concern. In the current retrospective study, we evaluated the incidence of infectious complications after prostate biopsy and identified the risk factors. MATERIALS AND METHODS: The study population included 1,195 patients who underwent a prostate biopsy between January 2007 and December 2012 at Chung-Ang University Hospital. Cases of febrile UTI that occurred within 7 days were investigated. Clinical information included age, prostate-specific antigen, prostate volume, hypertension, diabetes, body mass index, and biopsy done in the quinolone-resistance era. Patients received quinolone (250 mg intravenously) before and after the procedure, and quinolone (250 mg) was orally administered twice daily for 3 days. We used univariate and multivariate analysis to investigate the predictive factors for febrile UTI. RESULTS: Febrile UTI developed in 39 cases (3.1%). Core numbers increased from 2007 (8 cores) to 2012 (12 cores) and quinolone-resistant bacteria began to appear in 2010 (quinolone-resistance era). In the univariate analysis, core number> or =12 (p=0.024), body mass index (BMI)>25 kg/m2 (p=0.004), and biopsy done in the quinolone-resistance era (p=0.014) were significant factors. However, in the multivariate analysis adjusted for core number, the results were not significant, with the exception of BMI>25 kg/m2 (p=0.011) and biopsy during the quinolone-resistance era (p=0.035), which were significantly associated with febrile UTI. CONCLUSIONS: Quinolone resistance is the main cause of postbiopsy infections in our center. We suggest that further evaluation is required to validate similar trends. Novel strategies to find alternative prophylactic agents are also necessary.

OBJECTIVETo analyze the relationship between the prognosis and clinical factors of primary vesicoureteral reflux (VUR) patients under the condition of non-surgical treatment.
METHODThe medical records of the patients who were diagnosed as VUR by micturating cystourethrography (MCU) from January 2000 to December 2009 in Children's Hospital of Fudan University underwent non-surgical treatment, and followed up for more than one year then had repeated MCU, were retrospectively reviewed.
RESULTA total of 73 children (30 boys, 43 girls) were included in this study. The percentage of mild reflux (grade I-II) was 19.2% (14/73), that of moderate reflux (grade III) was 53.4% (39/73), and that of severe reflux (grade IV-V) was 27.4% (20/73). Among 73 patients, 27 (37.0%) patients were found to have renal damage. The average interval of repeated MCU was (1.29 ± 0.40) years (1 - 2 years). After follow-up, it was found that the reflux grade was relieved in 41 (56.2%) patients, of whom 27 (37.0%) patients achieved complete resolution, 32 (43.8%) patients did not have remission in reflux grade, of whom 13 (17.8%) patients had worsened reflux grade. Logistic regression analysis showed that VUR patients with renal damage at initial diagnosis was an important clinical factor to affect reflux remission (P = 0.000), complete resolving (P = 0.008) and result in worsening (P = 0.002).
CONCLUSIONA certain proportion of primary VUR patients could get reflux grade self-resolution, it was also quite common in severe VUR patients. VUR patients with renal damage at initial diagnosis was an important clinical factor affecting the reflux grade prognosis. Mild and moderate VUR patients with renal damage were at risk of worsening. VUR patients with high reflux grade had normal renal status could still get remission or even disappearance of VUR. But severe VUR patients with renal damage were still recommended to receive surgical therapy.
