The presence of bacteria in urine is called bacteriuria, which may be symptomatic or asymptomatic. The manipulation of the urinary tract during urodynamic study (UDS), which is an invasive procedure, can result in urinary tract infection (UTI). Studies on the use of prophylactic antibiotics for UDSs are contradictory. Some investigators concluded that they were valuable and others did not. The objective of this study is to evaluate the efficacy of antibiotic prophylaxis before UDS. This is a placebo-control randomized double-blind study.
Two-hundred and seventeen women affected by urinary incontinence were eligible for this study. All patients had presented negative urine culture previous to the UDS. They were randomized in four groups: group A received placebo, group B received 500 mg of levofloxacin, group C received 80 mg trimethoprim and 400 mg sulfamethoxazole and group D received 100 mg of nitrofurantoin. A urine culture was performed 14 days after the UDS.
We observed asymptomatic bacteriuria after the UDS in five patients in group A, one in group B, one in group C and one in group D. Only one patient on group A had symptomatic bacteriuria.We didn’t observe statistical difference between the groups. When we recategorized the patients in two groups, the incidence of bacteriuria was significantly higher in the placebo group compared with the antibiotic group.
The conclusion is that antibiotic prophylaxis before the UDS did not reduce the incidence of UTI in women within the target population.

Purpose: to evaluate the agreement between the urodynamic and ultrasonography diagnoses of urinary incontinence, as well as to correlate the variables of both examinations. Methodology: three hundred eighty-one patients with urine loss were selected, from the Sectior of Urogynecology and Vaginal Surgery of the Division of Gynecology, Escola Paulista de Medicina - Federal University of São Paulo. All of them were submitted to urodynamic study, according to the standardization of the International Society of Continence, and to ultrasonography of the bladder neck, with a 6 MHz trasvaginal transducer. We analyzed the maximum closing urethral pressure (MCUP) and the etiological diagnosis of the urine loss. In the ultrasonography, the position of the bladder neck was evaluated in relation to the inferior border of the pubic symphysis, and its mobility as well as the diameter of the urethra and bladder neck. The women were categoriaed according to the urodynamic study in to stress urinary incontinence, detrusor instability and mixed urinary incontinence. Results: 1) the bladder neck, at rest was most frequently above the inferior border of the pubic symphysis and, during effort, below or at the height of the bony reference, in the three groups; 2) the mobility of the bladder neck was similar in the groups; 3) there was no significant correlation between MCUP and the diameter of the urethra and of the bladder neck. Conclusion: we deem that ultrasonography of the bladder neck is always a complement to the clinical evaluation and the urodymanic study.

OBJECTIVE: to assess the concordance of different urodynamic parameters with simplified cystometry, thus improving the cost-benefit relationship for stress urinary incontinence (SUI) diagnosis in woman. METHODS: we evaluated retrospectively the medical records of thirty patients treated, from January 2000 to March 2001. All patients had been submitted to physical and gynecological examinations. A conventional urodynamic study had been made using a Dynograph R-611 recorder. Simplified cystometry had used a saline tube with "Y" connector, connected to a Foley 14 Fr catheter, which allowed measurement of intra-vesical pressure at the same time as physiological saline infusion. The following parameters were analyzed: residual volume, bladder capacity, complacency, involuntary detrusor contractions, and abdominal leak-point pressure. The Pearson test of agreement and the Wilcoxon signed rank test were used to verify the concordance between related samples, with p < 0,05. RESULTS: the average age was 50 years old (28-70). Concordance between studies for stress urinary losses was 67%, and for detrusor involuntary contractions, 90%. The average residual volume was significantly different: by simplified cystometry it was 16.8 ml versus 2 ml by conventional urodynamics (p < 0.01). The average maximum vesical capacity by urodynamic study was 440.5 ml, and by simplified cystometry, 387 ml (p < 0.05). Vesical complacency was on average, significantly larger in simplified cystometry (43.0 ml/cmH2O) than in the urodynamic study (31.5 ml/cmH2O), with p < 0.01. CONCLUSION: preliminary evaluations suggest that the urogynecologic propedeutic associated with cystometry is an option to be considered in the clinical and preoperative assessment of patients with SUI instead of conventional urodynamics, particularly when the latter is not available. Simplified cystometry is an accessible exam that grants comparable results for the detection of involuntary detrusor contractions and for the identification of urinary loss, providing the examiner with trustworthy data on vesical behavior.

Purpose: to analyze the prevalence of urogynecological symptoms and their relationship with final urodynamic diagnosis, and to compare the clinical sign of stress urinary incontinence with urodynamic diagnosis. Methods: a total of 114 patients were included in a retrospective study from June 2000 to January 2001. All patients were evaluated through medical interview, physical examination and urodynamic study. They were classified according to clinical symptom, presence of clinical sign of urine loss and urodynamic study. The data analysis was performed using a test to determine sensitivity, specificity, and positive and negative predictive values. Results: the mean age was 51 years (19-80), 61 patients (53.5%) were in menacme and 53 (46.5%) in postmenopausal stage. Ten (18.8%) were using hormone replacement therapy and 25 (21.9%) had been submitted to surgery for incontinence. The isolated clinical symptom of urine loss was reported in 41 (36.0%) patients, the isolated urgency/urgency-incontinence in 13 (11.4%) and mixed symptoms in 60 (52.6%). In the urodynamic study, of all patients with symptom of isolated urine loss, 34 (83%) had stress urinary incontinence (SUI), no patient had detrusor instability (DI), 2 (4.9%) had mixed incontinence (MI) and 5 (12.1%) had a normal result. Of all patients with isolated urgency/urgency-incontinence, in the urodynamic study, none had SUI, 5 (38.5%) had ID, 1 (7.7%) had MI and 7 (53.8%) had a normal result. Of the patients with mixed symptoms, we identified, on the urodynamic evaluation, 25 (41.6%) who had SUI, 10 (16.7%) ID, 10 (16.7%) MI and 15 (25.0%) a normal result. The clinical sign of urine loss was identified in 50 (43.9%) patients. A total of 35 (70%) had SUI on urodynamic study, 6 (12%) had SUI and another diagnosis and 9 (18%) did not have SUI. Urine loss was absent in 64 (56.1%) women. Of those 23 (35.9%) had SUI on urodynamic study, 7 (11%) had SUI and another diagnosis and 34 (53.1%) did not have SUI. Conclusions: clinical history and physical examination are important in the management of urinary incontinence, although they should not be used as the only diagnostic method. Objective tests are available and should be used together with clinical data.
