The aim of this study was to assess the usefulness of PCR for diagnosis of Trichomonas vaginalis infection among male patients with chronic recurrent prostatitis and urethritis. Between June 2001 and December 2003, a total of 33 patients visited the Department of Urology, Hanyang University Guri Hospital and were examined for T. vaginalis infection by PCR and culture in TYM medium. For the PCR, we used primers based on a repetitive sequence cloned from T. vaginalis (TV-E650). Voided bladder urine (VB1 and VB3) was sampled from 33 men with symptoms of lower urinary tract infection (urethral charge, residual urine sensation, and frequency). Culture failed to detect any T. vaginalis infection whereas PCR identified 7 cases of trichomoniasis (21.2%). Five of the 7 cases had been diagnosed with prostatitis and 2 with urethritis. PCR for the 5 prostatitis cases yielded a positive 330 bp band from bothVB1 and VB3, whereas positive results were only obtained from VB1 for the 2 urethritis patients. We showed that the PCR method could detect T. vaginalis when there was only 1 T. vaginalis cell per PCR mixture. Our results strongly support the usefulness of PCR on urine samples for detecting T. vaginalis in chronic prostatitis and urethritis patients.
OAB is associated with FMS. Moreover FMS increases with severity of OAB.
PurposeAn overactive bladder (OAB) affects a person's quality of life. Patients who suffer from OAB run to the toilet frequently to prevent incontinence, and this behavior increases their risk of falling and fear of falling. This study evaluated the influence of OAB on falls and concern about falling in females aged 40 and over living in urban and rural communities.MethodsWe conducted a population-based cohort study using King's Health Questionnaire (KHQ), the Korean version of Falls Efficacy Scale-International (KFES-I) and a questionnaire regarding falls, in females aged 40 and over in Guri city and Yangpyeong county. The data from 514 responders were analyzed. The definition of OAB was 'moderately' or 'a lot' of urgency, or urge incontinence in KHQ. Falls was defined as experience of falls in the last year. High fear of falling was defined as a score of 24 or over in KFES-I. The factors were analyzed by the exact chi-square test and Student's t-test. The multivariate logistic regression model was adopted in order to examine the effects of OAB on falls and concern about falling.ResultsOf the 514 responders, 98 fitted the criterion of OAB. Eighty-nine (17.3%) of the responders had experienced falls in the last year: twenty-seven (27.5%) in the group with OAB and 62 (14.9%) in the group without OAB. There was a significant association between falls and OAB (odds ratio [OR], 1.76; 95% confidence interval [CI], 1.00 to 3.08; P=0.0485), and between high fear of falling and OAB (OR, 2.72; 95% CI, 1.42 to 5.20; P=0.0024).ConclusionsUrgency and symptoms of urge incontinence increase the risk of falls in women aged 40 or older in the community. Early diagnosis and proper treatment may prevent falls and improve quality of life in OAB patients.
PurposeThe Gleason score (GS) is an important factor that is considered when making decisions about prostate cancer and its prognosis. However, upgrading of the GS can occur between transrectal ultrasonography (TRUS) biopsy and radical prostatectomy. This study analyzed the clinical factors predictive of upgrading of the GS after radical prostatectomy compared with that at the time of TRUS biopsy.Materials and MethodsWe analyzed the medical records of 107 patients who had undergone radical prostatectomy. Patients were divided into two groups. Group 1 consisted of patients in whom the GS was not upgraded, and group 2 consisted of patients in whom the GS was upgraded. Associations between preoperative clinical factors and upgrading of the GS were analyzed. Preoperative clinical factors included age, prostate-specific antigen (PSA), prostate volume, PSA density, GS of TRUS biopsy, maximum core percentage of cancer, percentage of positive cores, number of biopsies, location of positive core with maximum GS, high-grade prostatic intraepithelial neplasia (HGPIN), inflammation on biopsy, and clinical stage.ResultsAmong 85 patients, 42 (49%) patients had an upgraded GS after operation. TRUS biopsy core number of 12 or fewer (p=0.029) and prostate volume of 36.5 ml or less (p<0.001) were associated with upgrading of the GS. Preoperative clinical factors associated with nonupgrading of the GS were the detection of positive cores with a maximum GS at the apex (p=0.002) or in a hypoechoic lesion (p=0.002) in TRUS.ConclusionsIf the positive cores with maximum GS are located at the apex or in a hypoechoic lesion in TRUS, we can expect that the GS will not be upgraded. In patients with the clinical predictive factors of a prostate volume of 36.5 ml or less and TRUS biopsy core number of less than 12, we can expect upgrading of the GS after radical prostatectomy, and more aggressive treatment may be needed.
RESULTS• The median follow-up was 30 months in the TLRN group and 35.6 months in the RLRN group. Both groups were comparable regarding age, gender, body mass index (BMI), Fuhrman's grade, size of tumours and stage.• Kaplan-Meier curves and the log-rank test showed no significant difference between the TLRN and RLRN groups in 5-year overall (92.6% vs 94.5%; P = 0.669) and recurrence-free survival (92.0% vs 96.2%; P = 0.244).• In a Cox regression model with age, gender, Eastern Cooperative Oncology Group performance status, BMI, nuclear grade and T-stage adjusted variables, no significant difference was found between the two surgical approaches. CONCLUSION• The present study is the largest oncological analysis for laparoscopic radical nephrectomy (LRN) comparing transperitoneal and retroperitoneal approaches. The data from it provide the objective evidence to suggest similar oncological outcomes for both approaches to LRN. What's known on the subject? and What does the study add? Laparoscopic radical nephrectomy (LRN) can be performed by a retroperitoneal approach with similar efficacy compared to the transperitoneal approach. However, the oncological acceptance of LRN has been based on studies which have been carried out primarily by transperitoneal approach, and oncological results of the retroperitoneal approach alone are lacking.Our study confirmed that retroperitoneal laparoscopic radical nephrectomy is oncologically-equivalent to transperitoneal approach in homogeneous group with the final pathological diagnosis of clear cell RCC. OBJECTIVE• To investigate the oncological efficacy of retroperitoneal laparoscopic radical nephrectomy (RLRN) compared with transperitoneal laparoscopic radical nephrectomy (TLRN) for the management of clear-cell renal cell carcinoma (RCC). PATIENTS AND METHODS• With emphasis on survival and disease recurrence, a retrospective analysis was made of 580 patients who underwent TLRN (472 patients) or RLRN (108 patients) at 23 institutions between January 1997 and December 2007.• Inclusion criteria were clear-cell RCC, stage pT1 to pT2 without any nodal involvement, and metastasis.• Overall survival and recurrence-free survival curves were estimated using the Kaplan-Meier method.• To assess the association between the surgical approach and survival outcomes, Cox proportional hazard models were constructed.
