ABSTRACT
BACKGROUND: The purpose is to evaluate the psychometric properties of reliability and discriminant validity of the Brazilian Portuguese versions of two instruments used in the diagnosis of interstitial cystitis (IC): "The Interstitial Cystitis Symptom Index and Problem Index" (The O'Leary-Sant), and "Pelvic Pain and Urgency/Frequency (PUF) Patient Symptom Scale". METHODS: Three groups of patients were examined: a study group (subjects with IC), control group 1 (individuals with at least one IC symptom), and control group 2 (subjects without IC symptoms). Test-retest stability was evaluated at intervals of 3 to 7 days in the study group. Discriminant validity was examined in all three groups. RESULTS: The intraclass correlation coefficient (ICC) [95% confidence interval (CI)] results were 0.56 (range, 0.21-0.78) for The O'Leary-Sant Symptom Index, 0.48 (range, 0.10-0.73) for The O'Leary-Sant Problem Index, and 0.49 (range, 0.12-0.74) for the PUF. To analyze discriminant validity between groups, we used Fisher's exact test and odd ratio (OR) to identify differences. We obtained a P value<0.0001, which indicated that the null hypothesis was rejected; in other words, there was evidence that at least two different groups were compared to the proportion of patients with IC. CONCLUSIONS: The analyzed instruments did not reach appropriate values for reliability. Future studies are needed to analyze the psychometric measures of these instruments on a larger sample of patients with IC.
ABSTRACT
OBJECTIVES: Patients who have undergone pelvic radiotherapy can develop urinary complications such as actinic cystitis or fistulas and ultimately need urinary diversion, for which several techniques have been described. The purpose of this experimental study was to compare 2 different types of continent urinary diversion with the colonic pouch. METHODS: Sixteen dogs of both sexes, weighing 20-25 kg were divided into 3 groups: the pilot group consisted of 6 dogs used to standardize the technique. Group 1 consisted of 5 dogs that underwent the Monti technique to construct the conduit and the Abol-Eneim technique to promote continence. The final group, group 2, consisted of 5 dogs that underwent the intussusception technique for continence. In both techniques the same length of colon was used (20 cm). Urodynamic evaluation was performed at postoperative day 30. RESULTS: The compliance of the reservoir was similar among the groups. The capacity of the reservoir was greater and the continence mechanism was more effective in group 1. The length of the conduit was also longer in group 1. In group 2, the intussusception's mechanism was totally lost in 1 dog and partially in 2. CONCLUSIONS: The technique performed in group 1 allowed for the construction of a reservoir with greater capacity and the continence mechanism proved to be more efficient than in group 2. The length of the conduit was significantly greater in group 1.
