Current and future international patterns of care of neurogenic bladder after spinal cord injury.

PURPOSE: We aim to summarize the literature on international patterns of care for patients with neurogenic bladder (NGB) from spinal cord injury (SCI). METHODS: We performed a PubMed database search, hand review of references, communication with professional societies, and registry evaluations for pertinent data. RESULTS: Established patterns of care, including SCI registries and specialty centers, are available in high-resource countries such as the US and UK. As such, mortality rates from complications of NGB/SCI are lower. Access to intermittent catheterization supplies, among other resources, may be inadequate in many low-income regions. Cultural and religious beliefs may also hinder integration of proper bladder management in SCI patients. While guidelines exist in many parts of the world, it is unclear how rigorously they are disseminated or followed. CONCLUSIONS: While there is a paucity of high-level evidence, the differences in patterns of care are closely related to socioeconomic status and resources of the geographic area. Future research efforts should focus on improving access to diagnostic modalities, supplies, and specialists in these areas.

Nocturia, nocturnal incontinence prevalence, and response to anticholinergic and behavioral therapy.

To determine whether participants in the behavior enhances drug reduction of incontinence (BE-DRI) trial experienced reduction in the frequency of nocturia and/or nocturnal leakage during treatment with antimuscarinic phamacotherapy with or without additional behavioral therapy. We analyzed urinary diary data relating to nocturia and nocturnal incontinence before and after 8 weeks of study treatment in the BE-DRI trial, in which patients were randomly assigned to receive drug therapy with tolterodine tartrate extended-release capsules 4 mg alone or in combination with behavioral training. Chi-square tests assessed whether nocturia and nocturnal incontinence prevalence varied by treatment arm and paired t tests assessed the change in mean frequency of nocturia and nocturnal leakage. Among 305 women, 210 (69%) had an average of at least one nocturia episode at baseline. There were small but statistically significant differences (p < 0.001) in mean nocturia frequency and nocturnal incontinence frequency with both treatments after 8 weeks, but no significant difference between study treatment groups. Among these urge incontinent women, tolterodine with or without supervised behavioral therapy had little impact on either nocturic frequency or nocturnal incontinence.

The cost-effectiveness of preoperative testing (basic office assessment vs. urodynamics) for stress urinary incontinence in women.

OBJECTIVE: To compare the cost-effectiveness of preoperative testing strategies in women with stress incontinence symptoms, as although urodynamic testing is used to improve the diagnostic accuracy in women with incontinence, the clinical and economic consequences of different levels of testing have not been evaluated. MATERIALS AND METHODS: Decision analysis was used to evaluate basic office assessment (BOA) and urodynamic testing for women with stress incontinence symptoms who were candidates for primary surgical treatment. Costs were calculated using the Federal Register. Parameter estimates for the effectiveness of treatment for different diagnoses of incontinence were based on published reports. Incremental cost-effectiveness was defined as the cost in dollars per additional patient cured of incontinence. RESULTS: Urodynamics did not improve the effectiveness of treatment; both strategies of a BOA and urodynamic testing resulted in a cure rate of 96% after initial and secondary treatments. The mean cost of care (including initial and secondary treatments and outcomes) was similar for the two strategies ($5042 for BOA, $5046 for urodynamic testing). With BOA reduced testing costs were balanced by increased costs for patients who failed the initial treatment. Under baseline assumptions, one additional cure of incontinence (incremental cost-effectiveness) using the urodynamic strategy cost $3847, compared with BOA. By sensitivity analyses, BOA was less costly than urodynamics when the prevalence of genuine stress incontinence was > or = 80%. CONCLUSION: These findings do not support the routine use of urodynamics before surgery in women likely to have genuine stress incontinence, and provide the justification for randomized trials of preoperative testing strategies.

Standing cystourethrogram: an outcome measure after anti-incontinence procedures and cystocele repair in women.

OBJECTIVES: To evaluate the standing voiding cystourethrogram (VCUG) with lateral views as an outcome measure to objectively document the correction of the urethral angle and cystocele in women who underwent various types of pelvic surgery. METHODS: A control group of 76 continent patients was selected who had VCUGs performed for indications other than incontinence. Patients with preoperative and postoperative VCUGs after anterior vaginal wall suspension for urethral hypermobility and grade 1 or 2 cystocele (UH group) or repair of grade 3 cystocele (C group) were selected and compared with age-matched controls from the control group. RESULTS: Among the control group, the mean +/- SD urethral angle at rest was 12.5 degrees +/- 13.1 degrees and the urethral angle at straining was 24.7 degrees +/- 15.6 degrees (P <0.001). The urethral angle at rest increased significantly from women in their 20s to their 80s. In the UH group (n = 52), the preoperative mean urethral angle at rest and at straining was 25.7 degrees +/- 13.6 degrees and 42.6 degrees +/- 15.9 degrees, respectively, a difference of approximately 20 degrees. The postoperative urethral angles at rest and at straining did not statistically differ from those of the age-matched controls. In the C group (n = 36), the postoperative urethral angle at rest did not statistically differ from that of the age-matched controls. The lateral height of the cystocele demonstrated significant improvement in the UH and C groups. CONCLUSIONS: The standing VCUG is a reproducible outcome measure to preoperatively and postoperatively document the urethral angle. Using age-matched controls, a more objective definition of urethral hypermobility was obtained. Changes in cystocele height were observed postoperatively with a return to comparable age-matched control values.

[Interstitial cystitis: reevaluation of patients who do no respond to standard treatments]. / Cystites interstitielles: réévaluation des patients ne répondant pas aux thérapeutiques standards.

OBJECTIVE: Insterstitital cystitis (IC) is an uncommon disease without an existing positive diagnostic test. Our experience has been that it tends to be overly considered, with many patients treated for long periods with several different regimens and no improvement. This impression prompted a review of our recent experience in the exclusionary diagnosis of IC. MATERIAL AND METHODS: A retrospective review of patients referred to our specialty clinic between December 1995 and October 1998 revealed 23 patients (21 women, 2 men) who had been diagnosed with IC, and had received at least one treatment for this disease (intravesical DMSO or Heparin, Elmiron, 1-Arginine, or therapeutic hydrodistension) with little or no benefit. Our own evaluation of these patients included urinalysis, non-invasive uroflow, post void residual determination and office cystoscopy (all patients), filling cystometrogram and pressure-flow-EMG studies (21 patients), voiding cystourethrogram (17 patients), urethral MRI (9 patients), and other studies as indicated. The results of our reevaluation are reported. RESULTS: Of the 23 patients referred with a diagnosis of IC, only 4 were considered to meet the diagnostic criteria as established by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) after a thorough evaluation. One other patient did not meet the criteria but responded to medications for IC. Urethral pathology was a common finding (distal periurethral fibrosis causing obstruction in 5 patients, intraurethral wall diverticulum in 2, and chronic urethritis in 2), particularly among women with abnormal pressure flow studies during urodynamics. CONCLUSIONS: In our experience, many patients who carried the diagnosis of interstitial cystitis were found to have other causes contributing to their urinary symptoms after careful reassessment. Urodynamic studies were found to be of paramount importance in excluding the diagnosis in many cases. On the basis of our findings, we recommend that if local urethral tenderness is noted on physical examination or an abnormal pressure-flow relationship is seen during urodynamics, further investigation is warranted.

Overactive bladder: optimizing quality of care.

Overactive bladder (OAB), the symptom complex of urinary urgency and frequency with or without urge incontinence, affects the lives of millions of Americans. In recent years, more successful treatment options have emerged as advances have been made in understanding the pathophysiologic processes underlying OAB symptoms. However, because most therapeutic modalities for OAB are aimed at symptom resolution, rather than the treatment of distinct pathologic entities, a basic evaluation is required for all patients to establish whether existing (and treatable) pathologic processes are present. In the absence of these processes, symptom relief is both the objective and the outcome used to judge the efficacy of a specific modality. The type of therapy recommended for OAB may depend on several factors including age, existing behavioral patterns, estrogen status, degree of motivation, environmental surroundings, presence of other coexisting urinary symptoms, family support, and patient expectations. This article focuses on methods of identifying patients with OAB, and the role of developing strategies in treating this common disorder.

Up-regulation of a gene homologous to the human tumor necrosis factor receptor associated factor 6 gene in the obstructed rabbit bladder determined by differential display polymerase chain reaction.

PURPOSE: We identified differentially expressed genes in the rabbit bladder after partial outlet obstruction. MATERIALS AND METHODS: Differential display polymerase chain reaction (PCR) was performed on smooth muscle tissue from normal, 2 and 6-week obstructed rabbit bladders. Semiquantitative reverse transcriptase PCR, Western and RNA blot analysis were done to confirm messenger RNA and protein up-regulation. RESULTS: A signal transducing protein human tumor necrosis factor receptor associated factor 6 (TRAF6)-like protein was identified on differential display PCR. TRAF6-like protein was up-regulated in rabbit bladders after 2 weeks of partial outlet obstruction. Reverse transcriptase PCR demonstrated TRAF6-like protein in bladder muscle tissue and semiquantitative analysis confirmed up-regulation in 2-week obstructed tissue. These findings were confirmed by RNA and Western blot analysis. CONCLUSIONS: TRAF6-like protein is up-regulated during the early phase of bladder outlet obstruction in rabbits. To our knowledge involvement of this gene in bladder outlet obstruction has not been described previously. TRAF6 may have a role in the regulation of molecular changes during the early bladder response to outlet obstruction, such as the up-regulation of growth factors and proto-oncogenes. Further understanding of this signaling pathway and its role in bladder outlet obstruction may open new avenues for treating detrusor dysfunction.

Contractile protein expression in bladder smooth muscle is a marker of phenotypic modulation after outlet obstruction in the rabbit model.

PURPOSE: We determined changes in contractile protein expression before and after the relief of partial bladder outlet obstruction in the rabbit model and assessed their potential role as predictors of recovery. MATERIALS AND METHODS: We examined the ratio of the smooth muscle myosin heavy chain isoforms SM2-to-SM1, caldesmon isoform expression and bladder function in obstructed and unobstructed adult rabbit bladders. Cystometry, sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blot analysis were done to determine changes in bladder function and contractile protein expression. RESULTS: Overall we observed significant correlation of bladder weight with the SM2-to-SM1 ratio (p <0.05). Regardless of the duration of obstruction (up to 10 weeks) the ratio appeared to stabilize around a value comparable to that in fetal rabbit smooth muscle cells, suggesting a reversal of SM2 and SM1 expression to a level similar to that at the fetal stage. The pattern of h and l-caldesmon isoform expression showed an increase in l-caldesmon expression in obstructed bladders. Except for decreased leak point pressure in the obstructed group we noted no statistically significant urodynamic changes in bladder capacity or compliance. CONCLUSIONS: There is significant correlation of bladder weight, which is the best known marker of obstruction, with the SM2-to-SM1 ratio. The myosin heavy chain isoform expression ratio appears to be an indicator of phenotypic modulation in bladder smooth muscle before and after the relief of bladder outlet obstruction. Thus, it may be useful as a marker of bladder dysfunction and predictor of functional recovery. Regression to a fetal pattern of protein expression may suggest irreversible damage to smooth muscle cells, possibly limiting recovery.

Practical outcome measures for assessing efficacy of incontinence procedures.

Standard treatment for urinary incontinence in women has evolved during the past few decades. Conservative measures such as pelvic floor exercises and biofeedback may be effective and have been advocated for the past several years. However, the availability of other methods that are potentially more invasive yet efficacious provides a wider range of choices for women with urinary incontinence. With these alternatives comes opportunity and responsibility to assess how successful these treatments are. This article explores current methods of analyzing outcomes of urinary incontinence treatments.

Vaginal vault fixation and prevention of enterocele recurrence by high midline levator myorraphy: physical examination and questionnaire-based follow-up.

OBJECTIVES: To assess outcome following a vaginal repair (high midline levator myorraphy, HMLM) for vaginal vault prolapse. METHODS: Women were identified who had undergone HMLM between December 1995 and September 1998. A structured telephone interview consisting of 5 questions was conducted in all those who could be reached. The most recent results of physical examination, based on office records, were also collected. RESULTS: Thirty-five of 47 women completed the interview (average age 71 years, mean time since surgery, 27.9 months). Five patients had developed recurrent prolapse requiring repair (anterior enterocele in 3, vault prolapse in 1, symptomatic cystocele in 1). Recurrent cystoceles were noted on examination in 7 women (5 grade 1, 2 grade 2). Overall, 17 women were extremely satisfied with the result (>90% satisfied); 6 were dissatisfied (<50%). Five women were noted to have transiently reduced unilateral ureteral drainage intraoperatively, and all cases were resolved after the removal or replacement of one of the levator myorraphy sutures. One patient required re-exploration for ureteral obstruction, which resolved after replacement of a suture and stenting. CONCLUSIONS: Levator myorraphy is safe, effective, and easily taught. The rate of recurrent prolapse associated with this technique is similar to other techniques for vaginal vault fixation, but it avoids the disadvantages of an abdominal approach and is more technically straightforward to perform than sacrospinalis fixation.

The levator myorraphy repair for vaginal vault prolapse.

Various techniques have been described for the repair of vaginal vault prolapse after hysterectomy. Because of inherent difficulties associated with the sacrospinous fixation, a new repair, the levator myorraphy, was devised to simplify reconstruction of the pelvic floor 10 years ago. This repair results in a restored vaginal axis and prevention of posterior enterocele recurrence by recreating the levator shelf high within the peritoneal cavity and fixing the vault in that position. Because this procedure can be performed from a vaginal approach, morbidity is minimized. Over this 10-year time period, we have performed the levator myorraphy in over 120 women. We believe this approach can be easily taught, is highly effective, and results in a repair that most closely restores the normal anatomic position.

Sexual function after vaginal surgery for stress incontinence: results of a mailed questionnaire.

OBJECTIVES: To address the issue of sexual dysfunction after vaginal surgery for incontinence based on responses to a mailed questionnaire. METHODS: A sexual function questionnaire was mailed to 93 women who underwent anterior vaginal wall suspension for stress urinary incontinence alone (group 1) or in conjunction with a concomitant posterior repair (group 2) at least 1 year previously. RESULTS: A total of 56 (60%) women responded. Following surgery, 10 (37%) women in group 1 reported themselves as sexually active and 12 (41%) in group 2, which was similar to preoperative values. Only 1 woman in group 1 and 3 women in group 2 attributed their sexual inactivity to their own lack of desire or inability to have intercourse. Overall, 20% of women noted pain during intercourse, a finding slightly lower than the preoperative incidence (29%). No difference in the incidence of dyspareunia was noted between groups. Still, several women (18%) reported intercourse to be worse following surgery. Women who were either premenopausal or on hormone replacement therapy were more likely to be sexually active following surgery (46%) than those not on hormone replacement (17%). CONCLUSIONS: Overall, the percentage of women who were sexually active did not appear to be affected by a vaginal suspension procedure for incontinence. Symptomatic vaginal narrowing was rare, even among women undergoing simultaneous posterior repair. Still, nearly 20% of women considered intercourse to be worse postoperatively, although not all women reported dyspareunia. The possible causes for postoperative sexual dysfunction require further investigation.

Questionnaire-based assessment of bladder dysfunction in patients with mild to moderate Parkinson's disease.

OBJECTIVES: To assess the lower urinary tract symptoms (LUTS) in men and women with mild to moderate Parkinson's disease (PD) using validated symptom questionnaires. METHODS: Eighty men and 39 women with mild to moderate PD (Hoehn and Yahr score less than 3) were mailed LUTS questionnaires to complete and return. Men received the American Urological Association Symptom Index and women received the Urogenital Distress Inventory-6. Patients not responding by mail were called and asked to complete the survey over the telephone. Control populations of both symptomatic and asymptomatic men and women (without PD) were identified for comparison. RESULTS: The overall response rate was 78%. Men with early-stage PD had higher American Urological Association Symptom Index scores than age-matched controls (total score of 12.0 versus 7.7, P <0.05) and scores similar to those reported for men with symptomatic benign prostatic hyperplasia (12.5). Specific items noted to be higher among the men with PD included questions regarding frequency and urgency. Women with PD had higher scores on the Urogenital Distress Inventory-6 than non-age-matched controls (total score of 4.8 versus 2.1, P <0.05), but lower scores than an age-matched group of neurologically intact women presenting for urologic evaluation of LUTS (6.9, P <0.05). CONCLUSIONS: On the basis of the responses to the validated symptom indexes, the development of LUTS appears to occur at an earlier stage of PD than was once appreciated. Prompt evaluation and treatment of patients with lower urinary tract complaints in the setting of PD may identify bladder dysfunction at an earlier, more treatable stage.

Transvaginal repair of postcystectomy peritoneovaginal fistulae.

To our knowledge, peritoneovaginal fistula is a complication of cystectomy that has not been reported before. We describe 2 patients in whom a transvaginal approach using a Martius flap was utilized to repair persistent vaginal leakage after cystectomy. At a mean follow-up of 20 months, both patients are free from vaginal leakage and have no evidence of recurrent fistula. This approach offers a safe and effective way to repair a peritoneovaginal fistula in a cystectomy patient.

Pressure flow analysis may aid in identifying women with outflow obstruction.

PURPOSE: We refined recently developed pressure flow cutoff values for female bladder outlet obstruction and applied these values in a consecutive group of women undergoing urodynamic testing for various lower urinary tract symptoms. MATERIALS AND METHODS: A total of 87 women with clinical obstruction determined by history and presenting complaint were enrolled in our prospective evaluation of pressure flow studies. We identified 3 groups of participants according to the suspected cause of obstruction, including prolapse in 33, previous incontinence surgery in 25, and no likely source of obstruction identified from history and physical examination only in 29. An additional 124 patients presenting for evaluation of stress urinary incontinence served as controls. Optimal cutoff values for determining obstruction were developed using receiver operating characteristic curves. To determine the prevalence of bladder outlet obstruction these values were prospectively applied to 106 women undergoing urodynamics for various voiding complaints. RESULTS: In controls the average maximum flow rate was 23 cc per second and average detrusor pressure was 21.9 cm. water, whereas the corresponding values in those with clinical obstruction were 10.7 cc per second and 40.8 cm. water (p <0.001). No differences were noted in the various obstruction groups. Receiver operating characteristics analysis revealed that cutoff values of 11 cc per second or less and 21 cm. water or more optimized the selection of patients with bladder outlet obstruction. Using these values we noted a bladder outlet obstruction prevalence of 20% in a consecutive cohort of women undergoing urodynamic studies at our center. CONCLUSIONS: We propose cutoff pressure flow values for identifying women with bladder outlet obstruction although they should be used only in conjunction with the overall clinical situation. Neither pressure flow data only nor clinical symptoms alone may be sufficient for diagnosing obstruction in women.

Altered response to partial bladder outlet obstruction in mice lacking inducible nitric oxide synthase.

INTRODUCTION: Following prolonged partial bladder outlet obstruction (BOO) in the mouse, cholinergic mediated detrusor contractility decreases. Previous work has demonstrated an increase in the inducible form of nitric oxide synthase (iNOS) at the mRNA and protein levels soon after obstruction. Since nitric oxide (NO), the product of the action of iNOS on molecular oxygen and l-arginine, produces vasodilation and decreases platelet aggregation, we believe it is an integral part of the initial detrusor response to obstruction. These experiments evaluated the detrusor response in mice incapable of producing iNOS. MATERIALS AND METHODS: Wild type and knockout mice were partially obstructed for 1, 3, and 5 weeks. Physiologic evaluation consisted of cystometric analyses, and muscle strip studies in response to cholinergic and electrical stimulation. Strips were also relaxed with L-arginine, sodium nitroprusside, and 8-bromoguanosine 3' - 5' cyclic GMP, after precontraction. RESULTS: After 5 weeks of obstruction, both wild type (WT) and knockout (KO) mouse bladders increased significantly in weight. WT bladders obstructed for 5 weeks had the greatest capacity (increase of 42%, p = 0.022), and a decreased contractile response to carbachol (decrease of 32% at 10-5 M, p = 0.018). No differences were noted at 1 and 3 weeks of obstruction. In contrast, KO mice had a significantly larger bladder capacity at 1 week of obstruction compared with WT, and had significantly lower responses to electrical stimulation than WT at the same time (p = 0.03). Additionally, after 5 weeks of obstruction, bladder capacity and contractility returned to baseline levels in KO mice, at a time when WT mice had significantly larger capacity and decreased contractility. CONCLUSIONS: Bladder function following partial BOO in mice incapable of producing iNOS differed significantly from the normal response. Our data suggest that generation of iNOS soon after obstruction is necessary to prevent detrusor dysfunction at that time. Moreover, the enhanced function seen in KO bladders after longer periods of obstruction (5 weeks) in comparison to WT bladders suggests that reactive nitrogen species-induced protein nitrosylation may be involved in the loss of contractile function observed after more prolonged periods of obstruction.

Identifying patients who require urodynamic testing before surgery for stress incontinence based on questionnaire information and surgical history.

OBJECTIVES: To determine whether knowledge about previous surgical history for incontinence and responses to a validated lower urinary tract symptom questionnaire for women could identify those who should undergo urodynamic testing before surgery for stress urinary incontinence (SUI). METHODS: A retrospective analysis of all women who completed the Urogenital Distress Inventory-6 questionnaire (UDI-6) and then underwent complete urodynamic studies was conducted. The critical urodynamic diagnoses to determine before anti-incontinence surgery were defined as coexisting SUI and detrusor instability (DI), Valsalva leak point pressure less than 60 cm H(2)O, and DI alone in women suspected clinically of having SUI. Models were established for deciding who should undergo urodynamic studies on the basis of questionnaire responses and information about previous surgical history. Cost savings and the ability of the various models to identify patients with critical urodynamic diagnoses were calculated. RESULTS: A total of 174 women completed the UDI-6 and underwent urodynamics studies. Sixty-two had SUI (36%), 54 had DI (31%), 18 had both SUI and DI (10%), and 19 women suspected of having SUI were found instead to have DI (11%). Among women with SUI, 39 had a Valsalva leak point pressure less than 60 cm H(2)O (63%). No group of question responses or combination of question responses and presence of previous incontinence surgery was able to identify all three critical urodynamic diagnoses with statistical significance. Still, the combination of a response of "2" or "3" to question 3 on the UDI-6 and a positive history of previous surgery would have identified 91% of the critical diagnoses, and a substantial cost savings would have been realized. CONCLUSIONS: Using the UDI-6 and information obtained from the patient's history to determine who should undergo urodynamic testing before surgery for SUI can result in substantial cost savings without sacrificing patient care.

Reversing the tide: emerging options for treating overactive bladder symptoms in women.

The symptom complex of urinary urgency, frequency, nocturia, and urge incontinence, also known as the "overactive bladder" syndrome, affects the lives of millions of American women. As the symptoms are nonspecific, several different etiologies may be responsible. In many women, however, no discernible source can be identified. If a basic evaluation, including history, physical examination, urinalysis, and postvoid residual determination, fails to identify a source for the complaints, empiric treatment with behavioral intervention or a trial of medication may be offered to control symptoms. Certain patients will require a more detailed evaluation, particularly if conservative measures fail to provide relief. The role of advanced diagnostic strategies and the emergence of new treatment modalities are discussed.

Predictability of urodynamic findings based on the Urogenital Distress Inventory-6 questionnaire.

OBJECTIVES: The Urogenital Distress Inventory (UDI-6) is a validated 6-item questionnaire that assesses lower urinary tract symptoms, including incontinence, in women. Similar indexes developed in men to evaluate symptoms of benign prostatic hyperplasia have failed to show a relationship with urodynamic (UD) parameters indicating bladder outlet obstruction (BOO). In this study, we sought to determine whether UDI-6 responses could predict information obtained during UD evaluations. METHODS: All women referred to our clinic with lower urinary tract complaints who completed a UDI-6 questionnaire and subsequently underwent UD evaluation were included (n = 128). UD findings used for analysis included Valsalva leak point pressure (VLPP), maximum flow rate (Qmax), and detrusor pressure at Qmax (PdetQmax). BOO was defined as Qmax of 1 5 mL/s or less and PdetQmax of greater than 20 cm H2O; detrusor overactivity (DO) was defined as any rise in detrusor pressure associated with urge during filling. RESULTS: The most common chief complaints were incontinence (mixed, 26.6%; stress, 20.3%; and urge, 13.3%), urgency/frequency (14.1%), and symptomatic prolapse (10.1%). There was a moderate correlation between a positive response to question 3 (stress urinary incontinence [SUI]) and leakage with strain or cough during UD evaluation (correlation coefficient = 0.51). In fact, most patients answering that SUI was moderately or greatly bothersome were found to have stress-induced leakage during the UD evaluation (82%), which differed significantly from those who reported no bother (Fisher's exact test, P = 0.0006). Severity of leakage assessed by VLPP, however, did not correlate with the severity assessed by any question. With regard to BOO in women, most patients who answered that incomplete emptying was their most bothersome symptom had BOO (61%), and most women with a different main complaint were unobstructed (73%, P <0.002). Finally, 30 of 36 women who answered that leakage related to urgency was moderately or greatly bothersome were found to have DO, which was significantly different than the incidence of DO in women who did not report this complaint (correlation coefficient = 0.38, P <0.001). CONCLUSIONS: Unlike similar indexes used to assess lower urinary tract symptoms in men, specific items from the UDI-6 may provide predictive information regarding UD findings in women, particularly with regard to SUI, BOO, and DO. However, if VLPP is considered vital to planning treatment, UD studies will still be required, since no question could estimate the severity of incontinence as determined by serial VLPP measurement.
