Translation and validation into Brazilian Portuguese of the English version of the International Consultation on Incontinence Modular Questionnaire for Male Lower Urinary Tract Symptoms (ICIQ-MLUTS).

OBJECTIVES: To translate and cross-culturally adapt the English version of the International Consultation on Incontinence Modular Questionnaire for Male Lower Urinary Tract Symptoms (ICIQ-MLUTS) into Brazilian Portuguese and evaluate its psychometric properties. INTRODUCTION: Male lower urinary tract symptoms (LUTS) are frequent and commonly assessed with questionnaires. The ICIQ-MLUTS is a robust instrument that investigates the main aspects of LUTS in men and their impact on quality of life. Although highly recommended, Grade A is not as popular as the International Prostate Symptom Score (IPSS) and remained untranslated and unvalidated for Brazilian Portuguese. METHODS: After authorization by the Advisory Board of the International Consultation on Incontinence (ICIQ) the translation process was conducted according to the standard guidelines and the ICIQ validation protocol. Internal consistency was assessed using Cronbach's ⍺ coefficient and values > 0.7 were considered satisfactory. To assess test-retest reliability and reproducibility, Spearman's correlation coefficient and intraclass correlation coefficient were used. For group data, a Spearman correlation coefficient or an intraclass correlation coefficient of at least 0.70 demonstrates good test-retest reliability. A p < 0.05 was considered significant. RESULTS: One hundred and eighty-six, aged 61.41 ± 11.01 years, suffering from LUTS participated in the study between January 2021 and October 2022. Cronbach's ⍺, 0.875, demonstrated the internal consistency of the Portuguese version of ICIQ-MLUTS. The intraclass correlation coefficient of 0.912 (0.882; 0.935 - 95% CI) for the test-retest evidenced the stability and validity of the instrument. Likewise, Spearman's correlation coefficient highlighted the agreement between IPSS and ICIQ-MLUTS, 0.906, <0.001. DISCUSSION: The Portuguese version of the ICIQ-MLUTS demonstrated internal consistency, stability, and validity, in addition to agreement with the IPSS. CONCLUSION: The ICIQ-MLUTS, translated and validated into Brazilian Portuguese, is a robust and reliable instrument to assess LUTS in Brazilian men and can be used in the evaluation of treatment and research.

Validation of Visual Prostate Symptom Score (VPSS) in Brazilian Sample Population.

PURPOSE: The aim of the study was to evaluate the reliability and validity of the Visual Prostate Symptom Score (VPSS), its correlation with the International Prostate Symptom Score (IPSS), and the time required and need for help when completing the instrument. We also aimed to identify variables associated with difficulty completing these instruments. DESIGN: Longitudinal, prospective correlational study. SUBJECTS AND SETTING: The target population was Brazilian men from different cities within the state of São Paulo with lower urinary tract symptoms followed in urological consultation at a university hospital during October 2017. The sample comprised 59 patients with a mean age of 66.53 years. METHODS: Reliability of the VPSS was evaluated using a test-retest approach and its convergent validity with the IPSS. Cronbach α coefficient was also calculated. Both questionnaires were self-administered and, in case of difficulty of comprehension, assistance was provided. RESULTS: Mean completion time of the IPSS was 6.56 minutes and for VPSS was 5.02 minutes. The variables skin color and educational level were associated with the difficulty in completing the IPSS and for comprehending meaning of the VPSS pictograms. Internal consistency evaluated using Cronbach α coefficient was 0.74 for IPSS and 0.15 for VPSS, respectively. Test-retest reliability testing revealed that both instruments had a high intraclass correlation index (>0.75). There was a significant correlation between the health-related quality of life (QoL) scores of the 2 instruments (0.71, P = .0001) and between the total score of each instrument with its corresponding QoL score. CONCLUSION: Although time for response of the VPSS was shorter and it demonstrated good test-retest reliability, it more frequently required help to answer. The VPSS showed low internal consistency and low correlation with the IPSS (except for the QoL item).

Detrusor underactivity versus bladder outlet obstruction clinical and urodynamic factors.

OBJECTIVES: To evaluate the lower urinary tract symptoms, classified by the International Prostate Symptom Score (IPSS), urodynamic results (Watts Factor (WF), Bladder Contractility Index (BCI), and post void residual (PVR), in order to differentiate Detrusor Underactivity (DU) from Bladder Outlet Obstruction (BOO). METHODS: Retrospective observational study performed from 2011 to 2018 at the Hospital das Clínicas of Unicamp. Two phases were done: first, to estimate sample size, and second, to evaluate the predicted parameters. Male patients with range age from 40 to 80 years were included. Patients were divided into two groups: Group 1, without BOO and with DU; Group 2, with BOO. Variables analyzed: age, comorbidities, symptoms, urodynamic data (BCI and WF) and PVR. RESULTS: Twenty-two patients were included in each group, with medians of 68 (Group 1) and 67.5 years old (Group 2) (p = 0.8416). There was no difference for comorbidities. In relation to IPSS, medians were: 16.5 and 20.5, respectively (p = 0.858). As for symptoms, there was predominance of combination of storage and voiding symptoms in the two groups (p = 0.1810). Regarding PVR, 15 patients in Group 1 and 16 in Group 2 presented PVR> 30mL (p = 0.7411). BCI presented median values of 75 and 755.50 for Group 1 and Group 2, respectively (p < 0.0001), while WF had medians of 22.42 and 73.85 (p < 0.0001). CONCLUSION: Isolated symptoms, classified by IPSS and PVR, could not differentiate patients with DU from those with BOO, but it was possible using urodynamic data.

Proposal of a new way to evaluate the external sphincter function prior male sling surgey.

OBJECTIVE: To propose a new way to objectively evaluate the external sphincter function prior to male sling surgery. MATERIALS AND METHODS: We evaluated the pre-operative sphincter function throughout sphincter pressure at rest (SPAR) and sphincter pressure under contraction (SPUC) obtained throughout urethral profilometry profile (UPP) of 10 consecutive patients (age range, 54-79 years) treated with the retrourethral transobturator sling (RTS) for stress urinary incontinence (SUI) because of prostate surgery. The primary endpoint for surgery success rate was post-operative pad weight test. This was correlated to preoperative pad test, RT, SPAR and SPUC. Post-operatively patients were classified as continent (no pad use) and those who still were incontinent. RESULTS: Mean SPUC in the continent and incontinent group was respectively 188 + 8.8 (median 185.1, range 181 to 201) and 96.9 + 49.4 (median 109.9, range 35.6 to 163.6) (P = 0.008). Mean 24-hour pad test was 151 + 84.2gm (median 140, range 80 to 245) and 973 + 337.1gm (median 1940, range 550 to 1200) in post-operative continent and incontinent groups respectively (P = 0.008). The repositioning test (RT) was positive in all continent patients except one. The RT was also positive in three incontinence patients (false positive). In all post-operative continent patients SPUC was higher than 180cmH2O and pre-operative pad test was less than 245gm. CONCLUSIONS: SPUC seems to be a way for optimizing the sphincter evaluation as well to become a useful tool for patient selection prior to RTS surgery.

Effects of nitric oxide inhibitors in mice with bladder outlet obstruction.

PURPOSE: To investigate the lower urinary tract changes in mice treated with L-NAME, a non-selective competitive inhibitor of nitric oxide synthase (NOS), or aminoguanidine, a competitive inhibitor of inducible nitric oxide synthase (iNOS), after 5 weeks of partial bladder outlet obstruction (BOO), in order to evaluate the role of constitutive and non-constitutive NOS in the pathogenesis of this experimental condition. MATERIALS AND METHODS: C57BL6 male mice were partially obstructed and randomly allocated into 6 groups: Sham, Sham + L-NAME, Sham + aminoguanidine, BOO, BOO + L-NAME and BOO + aminoguanidine. After 5 weeks, bladder weight was obtained and cystometry and tissue bath contractile studies were performed. RESULTS: BOO animals showed increase of non-voiding contractions (NVC) and bladder capacity, and also less contractile response to Carbachol and Electric Field Stimulation. Inhibition of NOS isoforms improved bladder capacity and compliance in BOO animals. L-NAME caused more NVC, prevented bladder weight gain and leaded to augmented contractile responses at muscarinic and electric stimulation. Aminoguanidine diminished NVC, but did not avoid bladder weight gain in BOO animals and did not improve contractile responses. CONCLUSION: It can be hypothesized that chronic inhibition of three NOS isoforms in BOO animals leaded to worsening of bladder function, while selective inhibition of iNOS did not improve responses, what suggests that, in BOO animals, alterations are related to constitutive NOS.

Parameters of two-dimensional perineal ultrasonography for evaluation of urinary incontinence after Radical Prostatectomy.

INTRODUCTION: Urinary incontinence remains a major concern for patients undergoing radical prostatectomy. Its prevalence can reach 20% in the late postoperative period. MATERIALS AND METHODS: This clinical study investigated the differences of a dynamic evaluation of the urethra and pelvic floor contraction using perineal ultrasound in men without prostate surgery and in men submitted to radical prostatectomy with and without stress urinary incontinence. Ninety two male patients were included, which 70% of them underwent radical prostatectomy (RP) for more than one year. Thirty one men with clinically post prostatectomy incontinence were compared by two-dimensional (2D) perineal ultrasound to 34 patients without post prostatectomy incontinence and to 27 men without surgery in two centers in Brazil. RESULTS: Our results showed that the continent group presented the urethral angle at rest significantly lower than the prostate group (p = 0.0002). We also observed that the incontinent group showed the displacement of the anterior bladder neck during contraction significantly lower than the continent group (p = 0.008). CONCLUSIONS: We found that the continent group presented the urethral angle at rest significantly lower than the prostate group. The incontinent group also showed the anterior bladder neck displacement during contraction significantly lower than the continent group. It was more evident when the severe incontinent group and the continent group were compared.

[Adaptation of the O'Leary-Sant and the PUF for the diagnosis of interstitial cystitis for the Brazilian culture]. / Adaptação à cultura brasileira dos questionários The O'Leary-Sant e PUF, usados para cistite intersticial.

The aim of this study was to translate and adapt the instruments known as The O'Leary-Sant and PUF to the Brazilian culture used in the diagnosis of interstitial cystitis. We followed the methodological steps recommended by the international literature for cultural adaptation. The steps of translation, synthesis of translations and back translation were performed satisfactorily and evaluation the versions of the synthesis by the panel of experts has resulted in some changes, ensuring the equivalence between the original and translated versions. The PUF was pretested among 40 subjects and The O'Leary-Sant in a sample of 50 individuals due to the need for adjustments due to the low education population. The translation and adaptation process was successful and the instruments, after some modifications, proved easy to understand and complete quickly. However, this is a study prior to the validation process and will be promoting the use of the instrument in new research to assess its measurement properties.

Childhood enuresis is a risk factor for bladder dysfunction in adult life?

AIMS: To verify the relationship between enuresis in childhood and the type of urinary incontinence in adults, considering the gender and age. METHODS: In this retrospective cohort study the database used contained the records of patients who had with urinary complaints and underwent urodynamic studies in the period from 1999 to 2008. A multinomial logistic regression model was adjusted for the type of UI. RESULTS: A total of 661 patient records were analyzed, 585 (88.5%) women and 76 (11.5%) men, with mean age 54 (SD = 13.3). Patients with urge urinary incontinence (UUI) were compared to those with stress urinary incontinence (SUI) and the variables associated were the presence of enuresis in childhood (OR = 2.37, IC: 1.43-3.92) and age >50 years (OR = 2.64, CI: 1.68-4.15). Comparing patients with mixed urinary incontinence (MUI) and SUI, the presence of enuresis was also associated ((OR = 1.77, CI: 1.15-2.73) and the age of more than 50 years (OR = 1.71, CI: 1.19-2.44). For both categories of urinary incontinence, the variable sex was not associated. CONCLUSIONS: Individuals with MUI and UUI in adult life were more likely to have a history of enuresis in childhood than those with SUI.

Laparoscopic treatment of lymphoceles after renal transplantation.

OBJECTIVE: Lymphocele formation following renal transplantation is a frequent complication and may affect as many as 49% of patients. Operative treatment of symptomatic post transplant lymphocele (PTL) consists of wide drainage of the fluid collection into the abdominal cavity by excising its wall, connecting the lymphocele cavity to the intraperitoneal space. Laparoscopic fenestration seems to be the best treatment as it combines satisfying success rates with a minimally invasive approach. The aim of the study was to review a single center experience on the laparoscopic treatment of symptomatic PTL and detail relevant aspects of the surgical technique. MATERIALS AND METHODS: The data of 25 patients who underwent laparoscopic surgical treatment for a symptomatic lymphocele following kidney transplantation were retrospectively reviewed. Demographic data and surgical results were assessed. Detailed surgical technique is provided. RESULTS: Between 1996 and 2008, 991 patients received a kidney transplant at our institution. Twenty-five patients (2.52%) developed a symptomatic lymphocele and laparoscopic drainage was performed. The indications for surgical drainage were graft dysfunction (84%), local symptoms (16%) or both (32%). The mean time until surgical therapy was 14.2 ± 6 weeks. Mean hospital stay was 1.5 ± 0.2 days. Postoperative complications occurred in only 2 patients (8%) (one ureteral injury and one incisional hernia) and required reoperation. After a mean followup of 36.2 ± 4 months, only 1 patient had a symptomatic recurrence. CONCLUSIONS: Laparoscopic fenestration is an effective surgical technique to treat symptomatic lymphocele following kidney transplantation with low recurrence rate and long standing results.

Pelvic floor muscle training in the treatment of lower urinary tract dysfunction in women with multiple sclerosis.

AIMS: Evaluate the role of pelvic floor muscle training (PFMT) on the treatment of lower urinary tract dysfunction (LUTD) in multiple sclerosis (MS) patients. METHODS: In this randomized controlled trial, twenty seven female patients with a diagnosis of MS and LUTD complaints were randomized, in two groups: Treatment group (GI) (N = 13) and Sham group (GII) (N = 14). Evaluation included urodynamic study, 24-hr Pad testing, three day voiding diary and pelvic floor evaluation according to PERFECT scheme. Intervention was performed twice a week for 12 weeks in both groups. GI intervention consisted of PFMT with assistance of a vaginal perineometer. GII received a sham treatment consisted on the introduction of a perineometer inside the vagina with no contraction required. RESULTS: At the end of the treatment GI was complaining less about storage and voiding symptoms than GII. Furthermore, differences found between groups were: reduction of pad weight (P = 0.00) (Mean: 87,51 grams initial and 6,03 grams final in GI. 69,46 grams initial and 75,88 grams final in GII), number of pads (P = 0.01) (Mean: 3,61 initial and 2,15 final in GI. 3,42 initial and 3,28 final in GII) and nocturia events (P < 0.00) (Mean: 2,38 initial and 0,46 final in GI. 2,55 initial and 2,47 final in GII) and improvements of muscle power (P = 0.00), endurance (P < 0.00), resistance (P < 0.00) and fast contractions (P < 0.00), domains of PERFECT scheme. CONCLUSIONS: PFMT is an effective approach to treat LUTD in female with MS.

Parameters of 2-Dimensional Perineal Ultrasonography Before and After Male Sling Procedure for Urinary Incontinence After Radical Prostatectomy.

OBJECTIVE: To compare ultrasonographic patterns of 2-dimensional perineal ultrasonography in men in the preoperative and postoperative periods after transobturator sling deployment for the treatment of urinary incontinence after radical prostatectomy. Radiotherapy and radical prostatectomy are the primary treatments for localized prostate cancer. Studies comparing anatomic changes in men before and after radical prostatectomy based on perineal ultrasonography are scarce in the literature. METHODS: Thirty-one patients from 2 centers were selected for examination and surgery. They were allocated into mild and/or moderate and severe incontinence groups who underwent the transobturator sling procedure between August 2014 and August 2018. Perineal ultrasonography was performed in the preoperative period for 21 of these patients and 3-6 months postoperatively after the transobturator sling procedure for 30 patients. Hypermobility of the proximal urethra and voluntary contraction of the pelvic floor were evaluated during the Valsalva maneuver, perineal contraction and at rest. RESULTS: Clinical improvements of >50% were significantly more frequent in the mild and/or moderate vs severe incontinence group after male sling surgery (P = .035). Patients who demonstrated clinical improvement >50% showed a significantly greater displacement of the posterior portion of the bladder neck during contraction than those with clinical improvement <50% (P = .024). CONCLUSION: The most important finding of this study was the significant difference in the posterior displacement of the bladder neck during contraction in patients who showed an improvement >50% compared with those with an improvement <50%. These data support the use of perineal ultrasonography in evaluating and selecting patients for the male sling procedure.

Pelvic floor muscle training alone or in combination with oxybutynin in treatment of nonmonosymptomatic enuresis. A randomized controlled trial with 2-year follow up.

OBJECTIVE: To compare the results of the standard urotherapy alone and associated with pelvic floor muscle training alone, and in combination with oxybutynin in treatment of nonmonosymptomatic nocturnal enuresis. METHODS: A total of 38 children aged 5 to 10 years were randomized into three groups: Group I (n=12) that was submitted to standard urotherapy; Group II (n=15), standard urotherapy associated with pelvic floor muscle training; and Group III (n=11), standard urotherapy associated with pelvic floor muscle training and oxybutynin; the treatment lasted 12 weeks. The assessment tools used were playful bladder diary, and a 48-hour bladder diary, before and after treatment. After 2 years, patients were assessed by telephone using a standardized questionnaire. RESULTS: The data of children from the three groups were homogeneous at baseline. After 12-week treatment, all children showed improved symptoms and signs of nonmonosymptomatic nocturnal enuresis, but the differences were not significant among the groups. After 2 years, the three groups showed maintenance of treatment results, but no differences among them. CONCLUSION: All treatment modalities were effective regarding improved enuresis and lower urinary tract symptoms, but the sample was not large enough to show differences among groups.

Intradetrusor onabotulinumtoxinA injections are significantly more efficacious than oral oxybutynin for treatment of neurogenic detrusor overactivity: results of a randomized, controlled, 24-week trial.

OBJECTIVE: To prospectively compare the results of intradetrusor onabotulinumtoxinA injections and oral oxybutynin for urinary continence, urodynamic parameters and quality of life in patients with neurogenic detrusor overactivity due to spinal cord injury. METHODS: Adult patients under intermittent catheterization were randomized 1:1 to receive one injection of onabotulinumtoxinA 300U or oxybutynin 5mg, per oris, three times/day. Primary study endpoint was change in urinary incontinence episodes/24 hours and secondary study endpoints were maximum cystometric capacity, maximum detrusor pressure, bladder compliance and quality of life before randomization and at week 24. RESULTS: Sixty-eight patients participated in the trial. Significant improvements in urinary incontinence per 24 hours, all investigated urodynamic parameters and quality of life were observed in both groups. Compared with oral oxybutynin, onabotulinumtoxinA was significantly more efficacious for all parameters investigated. Non-response to treatment was higher for oral oxybutynin (23.5%) than onabotulinumtoxinA (11.8%). Dry mouth was the most common adverse in patients with oral oxybutynin (72%) and transient macroscopic hematuria in patients with onabotulinumtoxinA (28%). Only one patient with oral oxybutynin dropped out the study because of adverse effects. CONCLUSION: The comparison of the two study drugs showed that onabotulinumtoxinA was significantly more efficacious than oral oxybutynin with regard to continence, urodynamic parameters and quality of life.

Laparoscopic ileocystoplasty: an experimental study in pigs.

BACKGROUND AND PURPOSE: Bladder dysfunction may lead to urinary incontinence and progressive kidney deterioration. When clinical treatment fails, bladder augmentation is the operation of choice in most cases. The purpose of this study was the standardization of the technique of videolaparoscopic ileocystoplasty in a porcine model and demonstration of a tutor-supervised learning curve. MATERIALS AND METHODS: The study was conducted on 15 Large-White male pigs (20-25 kg) that underwent ileocystoplasty with 15 cm of distal ileum shaped into a using extracorporeal technique and laparoscopic ileovesical anastomosis. Operative time, ileovesical anastomosis time, intraoperative complications, and extravasation after anastomosis were evaluated. To assess the learning curve, the animals were divided into three groups of five: group I (operated on in collaboration with a tutor), group II (treated under the supervision of tutor), and group III (without the tutor's collaboration or supervision). RESULTS: Total surgical time and ileovesical anastomosis time revealed significant differences (P < 0.05) between groups I and III (70% reduction) as well as between groups II and III (64% reduction). CONCLUSIONS: Laparoscopic ileocystoplasty in pigs is feasible without special laparoscopic material. Ten initial procedures with a tutor's help were important for technique acquisition and mastery. A sharp increase in efficiency occurs between the tenth and fifteenth procedures. These procedures should be executed at least ten times in the presence of the tutor to enable the surgeon to overcome the learning curve.

Macroplastique implantation system for female stress urinary incontinence: long-term follow-up.

PURPOSE: To evaluate the 60-month outcome of the Macroplastique Implantation System (MIS) for the treatment of female stress urinary incontinence (SUI) caused by intrinsic sphincter deficiency evaluated by objective and subjective measures, including Quality of Life (QoL) impact. PATIENTS AND METHODS: Twenty-one women, mean age 47.4 years, with urodynamically diagnosed intrinsic sphincter deficiency were enrolled. They were assessed preoperatively by physical examination, QoL (King's Health Questionnaire), Stamey grading of incontinence, pad usage, 1-hour pad-weight test, and urodynamic testing. Patients underwent periurethral injection of MIS under local anesthesia. After 24-month follow-up, six patients were discharged from the group, and the remaining 15 patients were reassessed by means of objective and subjective parameters at 6, 12, 24, and 60 months after last treatment. RESULTS: Patients' QoL improved in all domains throughout the study. The overall subjective success rate was 80%. At 60 months, pad usage was reduced from a mean of 3.5/day to 0.9/day, and the 1-hour pad weight decreased from 53.8 to 5.9 g. Valsalva leak-point pressure testing demonstrated a 73.3% rate of cure/improvement. There was no significant statistical difference assessed by Stamey grading and objective cure at 6, 12, 24, and 60 months of follow-up. The data showed a stable overall outcome from 6 to 60 months. CONCLUSION: The MIS produced promising long-term subjective and objective outcomes, as well as long-lasting improvements in QoL. It should be considered a good option for certain cases of female SUI.

Continent urinary diversion in patients with pelvic irradiation: an alternative utilizing transverse colon reservoir.

The use of radiation therapy in pelvic malignancies increases the risk of urinary complications, sometimes being necessary urinary diversion. The risk of utilizing previously irradiated bowel should be avoided. The use of transverse colon is a safe and effective alternative. We present a heterotopic continent colonic reservoir with an easily catheterizable conduit.

Detrusor underactivity versus bladder outlet obstruction clinical and urodynamic factors

ABSTRACT Objectives: To evaluate the lower urinary tract symptoms, classified by the International Prostate Symptom Score (IPSS), urodynamic results (Watts Factor (WF), Bladder Contractility Index (BCI), and post void residual (PVR), in order to differentiate Detrusor Underactivity (DU) from Bladder Outlet Obstruction (BOO). Methods: Retrospective observational study performed from 2011 to 2018 at the Hospital das Clínicas of Unicamp. Two phases were done: first, to estimate sample size, and second, to evaluate the predicted parameters. Male patients with range age from 40 to 80 years were included. Patients were divided into two groups: Group 1, without BOO and with DU; Group 2, with BOO. Variables analyzed: age, comorbidities, symptoms, urodynamic data (BCI and WF) and PVR. Results: Twenty-two patients were included in each group, with medians of 68 (Group 1) and 67.5 years old (Group 2) (p = 0.8416). There was no difference for comorbidities. In relation to IPSS, medians were: 16.5 and 20.5, respectively (p = 0.858). As for symptoms, there was predominance of combination of storage and voiding symptoms in the two groups (p = 0.1810). Regarding PVR, 15 patients in Group 1 and 16 in Group 2 presented PVR> 30mL (p = 0.7411). BCI presented median values of 75 and 755.50 for Group 1 and Group 2, respectively (p <0.0001), while WF had medians of 22.42 and 73.85 (p <0.0001). Conclusion: Isolated symptoms, classified by IPSS and PVR, could not differentiate patients with DU from those with BOO, but it was possible using urodynamic data.

Test-retest reliability and discriminant validity for the Brazilian version of "The Interstitial Cystitis Symptom Index and Problem Index" and "Pelvic Pain and Urgency/Frequency (PUF) Patient Symptom Scale" instruments.

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.

Treatment of intrinsic sphincter deficiency using the Macroplastique Implantation System: two-year follow-up.

PURPOSE: To evaluate the 24-month outcome of the Macroplastique Implantation System (MIS) for the treatment of stress urinary incontinence (SUI) using objective and subjective measures, including quality-of-life (QoL) impact. PATIENTS AND METHODS: Twenty-one consecutive women with a mean age of 47.4 years and a mean body mass index 26.16 kg/m(2) having urodynamically diagnosed intrinsic sphincter deficiency (ISD) were enrolled. Patients were assessed preoperatively and postoperatively by physical examination, Stamey grading of incontinence, pad usage, pad weight test, and urodynamic measurements. Quality of life was assessed by the King's Health Questionnaire. Patients underwent transurethral injection of the MIS under local anesthesia on an outpatient basis. The mean volume injected was 6.3 mL. The data presented are based on 24-month followup from the last injection, and the patients were considered their own controls. RESULTS: Patient QoL improved in all domains. Ten patients (47%) considered themselves cured; three (14.3%) thought they were improved, and eight (38.1%) believed the procedure had failed. According to the subjective surgeon Stamey grading, 8 patients (38.1%) were considered cured, 5 (23.8%) improved, and 8 (38.1%) failed. Daily pad usage was reduced from a mean of 4.38 to 1.47. According to the pad weight test, 12 patients (57.1%) were dry and two (9.5%) improved, while in 7 (33.3%), MIS failed. Urodynamic testing demonstrated 10 patients (50%) dry and 5 (25%) improved. CONCLUSION: The MIS proved to have an outcome acceptable to patients and surgeons at 24-month followup. The procedure can be performed easily under local anesthesia.
