RESUMO
AIMS: The aim of this study was to compare the clinical characteristics of men with lower urinary tract symptoms (LUTS) grouped by 24-h urine output determined from a bladder voiding diary. METHODS: An online database was queried to identify men who completed a 24-hour bladder diary (24HBD), and the Lower Urinary Tract Symptom Score (LUTSS) questionnaire from 2015 to 2019 using a mobile app. Data from the bladder diary and questionnaire were contemporaneously matched within a 2-week period. Additional data, including maximum uroflow (Qmax ) and postvoid residual urine (PVR), were obtained from the electronic medical record (EMR). The cohort was divided into three groups: normal, oliguria, and polyuria based on their 24-hour voided volume (24HVV). The LUTSS, 24HVV, maximum voided volume (MVV), maximum flow rate (Qmax ), and PVR were compared between those with oliguria and polyuria. RESULTS: A total of 327 men (mean age 62, SD: 19) completed the LUTSS questionnaire and contemporaneous 24HBD. Of these, 61% had a normal 24HVV, 13% had oliguria, and 26% had polyuria. A total of 147 patients from the study cohort had contemporaneous Qmax and PVR abstracted from the EMR. There was no difference in symptom severity, bother, or PVR among the three patient groups. However, several objective metrics were significantly correlated with urine output. Men with oliguria, as compared to men with polyuria were older (65 vs. 55 years) and had lower MVV (260 vs. 470 mL), fewer voids/24 h (8 vs. 13), and lower Qmax (8.5 vs. 18.3 mL/s). CONCLUSIONS: These observations suggest that men with oliguria or polyuria and LUTS constitute easily distinguished phenotypes that might require different diagnostic and therapeutic algorithms. Those with oliguria were older, and had lower MVVs and much lower uroflows, suggesting that they are more likely to have underlying disorders such as bladder outlet obstruction and detrusor underactivity or may be patients with overactive bladder who reduced fluid intake to improve symptoms.

INTRODUCTION: Patients with lower urinary tract symptoms (LUTS) can be subcategorized into polyuria, normal or oliguria groups. Polyuria may be caused by pathologies including diabetes mellitus (DM), chronic kidney disease (CKD), diabetes insipidus (DI), or primary polydipsia (PPD). While fluid restriction is appropriate for some, doing so in all may result in serious complications. This study investigates the prevalence of these pathologies in LUTS patients with polyuria. MATERIALS AND METHODS: Two databases were retrospectively queried for men and women who filled out a lower urinary tract symptom score (LUTSS) questionnaire, 24-h bladder diary (24HBD) and were polyuric (>2.5 L/day). Patients were divided into four groups: poorly controlled DM, DI, an CKD grade 3 and PPD. One-way analysis of variance compared 24HBD and LUTSS questionnaires. Pearson correlation examined LUTSS and bother with 24-h voided volume (24 HVV), maximum voided volume (MVV) and total voids. RESULTS: Among 814 patients who completed a 24HBD, 176 had polyuria (22%). Of the patients with complete data, 7.8% had poorly-controlled DM, 3.1% had DI, 4.7% had CKD grade 3% and 84.4% had PPD. Amongst the four different sub-groups, significant differences were seen in 24 HVV (p < 0.001), nocturnal urine volume (NUV) (p < 0.001), MVV (p = 0.003), daytime voids (p = 0.05), nocturnal polyuria index (NPi) (p < 0.001) and nocturia index (Ni) (p = 0.002). Significance was also seen between LUTSS and bother subscore (r = 0.68, p < 0.001), LUTSS and total voids (r = 0.29, p = 0.001) and bother sub-score and total voids (r = 0.21, p = 0.019). CONCLUSIONS: 22% of patients with LUTS were found to have polyuria based on a 24HBD. Within this cohort, four sub-populations were identified as being demonstrating statistically significant differences in 24 HVV, NUV, MVV, daytime voids, NPi and Ni. Identifying the underlying etiology of polyuria should be carried out to safely treat patients with LUTS.

INTRODUCTION: Nocturia arises from a fundamental mismatch between nocturnal urine production, storage capacity, and sleep architecture, which may be driven by abnormalities of the genitourinary tract, but also by sleep disorders, medical diseases, patient actions/lifestyle factors, or medications. This article introduces a novel system for organizing the complex differential diagnosis for nocturia, as proposed by an international collective of practicing urologists, physician specialists, and sleep experts: "Sleep CALM"-Sleep Disorders, Comorbidities, Actions, Lower Urinary Tract Dysfunction, and Medications. METHODS: Narrative review of current evidence regarding the relevance of each "Sleep CALM" factor to nocturia pathogenesis, evaluation, and management. RESULTS: Nocturia and sleep disorders are highly intertwined and often bidirectional, such that nocturnal awakenings for reasons other than a sensation of bladder fullness should not be used as grounds for exclusion from nocturia treatment, but rather leveraged to broaden therapeutic options for nocturia. Nocturia is an important potential harbinger of several serious medical conditions beyond the genitourinary tract. Urologists should have a low threshold for primary care and medical specialty referral for medical optimization, which carries the potential to significantly improve nocturnal voiding frequency in addition to overall health status. Adverse patient actions/lifestyle factors, lower urinary tract dysfunction, and medication use commonly coexist with disordered sleep and comorbid medical conditions, and may be the primary mediators of nocturia severity and treatment response, or further exacerbate nocturia severity and complicate treatment. CONCLUSION: "Sleep CALM" provides a memorable and clinically relevant means by which to structure the initial patient history, physical exam, and clinical testing in accordance with current best-practice guidelines for nocturia. Although not intended as an all-encompassing diagnostic tool, the "Sleep CALM" schema may also be useful in guiding individualized ancillary testing, identifying the need for specialty referral and multidisciplinary care, and uncovering first-line treatment targets.

INTRODUCTION: The purpose of this study is to develop overactive bladder (OAB) phenotypes that can be used to develop diagnostic and treatment pathways and offer clues to the underlying etiologies of patients with OAB. MATERIALS AND METHODS: This is a retrospective, multicenter study of patients with lower urinary tract symptoms (LUTS). Evaluation included a 24-hour bladder diary (24HBD), the lower urinary tract symptoms score (LUTSS) questionnaire, uroflowmetry (Q), and post-void residual urine (PVR) measurement. Patients completed the 24HBD and LUTSS on a smartphone application or paper. Those with an OAB symptom sub-score (OABSS) ≥ 8 were included. An expert panel developed a phenotype classification system based on variables considered to be important for treatment. RESULTS: The following variables were selected for inclusion in the phenotype modeling: 24-hour voided volume (24HV), maximum voided volume (MVV), Qmax and PVR. Subjects were divided into three phenotypes based on the 24HV: polyuria (24HV > 2.5 L), normal (24 HV 1-2.5 L), and oliguria (24HV < 1 L). Each phenotype was subdivided based on MVV, Qmax & PVR, resulting in 18 sub-types. Five hundred thirty-three patients, 348 men and 185 women, completed the LUTSS and 24HBD. OAB was present in 399 (75%) - 261 men and 138 women. The prevalence of the primary phenotypes was polyuria (25%), normal (63%), and oliguria (11%). CONCLUSIONS: Classification of OAB variants into phenotypes based on 24HV, MVV, Qmax, and PVR provides the substrate for further research into the diagnosis, etiology, treatment outcomes and development of granular diagnostic and treatment algorithms.

INTRODUCTION: There is a paucity of data about augmentation cystoplasty (AC) in multiple sclerosis (MS) patients with refractory lower urinary tract symptoms (LUTS). The aim of this study is to evaluate the long term outcomes and morbidity of these procedures in MS patients. MATERIALS AND METHODS: This is a retrospective observational study of consecutive patients (1984-2017) with MS and refractory LUTS who underwent AC with or without a continent/incontinent abdominal stoma or urinary diversion. Pre and postoperative evaluations included routine labs, videourodynamic studies (VUDS), cystoscopy, and upper tract imaging. Long term outcomes and complications were assessed by validated questionnaires and/or chart review. RESULTS: There were 17 patients (12 women, 5 men) ranging in age from 34-77 years. Thirteen patients were wheelchair-bound (10 quadriplegics, 3 paraplegics). Indications included neurogenic detrusor overactivity (NDO) in two, low bladder compliance (LBC) in 13 and both NDO and LBC in two. One patient committed suicide at 3 months, and one was lost to follow up. Of the remaining 15, median follow up was 13 years (range 4-22), and 11 were followed up until death. Overall, 14/15 (93%) had a successful outcome based on the Patient Global Impression of Improvement (PGI-I). With respect to incontinence, 14/15 (93%) had a successful outcome based on the Simplified Urinary Incontinence Score (SUIS). Median bladder capacity increased from 180 mL to 605 mL (p < 0.001). Median maximum detrusor pressure decreased from 63 cm H2 O to 18 cm H2O (p < 0.003). Two patients underwent stomal stenosis revisions, four patients had pyelonephritis, and two patients developed de novo bladder stones. CONCLUSIONS: AC is a major surgical procedure with high potential morbidity, but these data suggest that AC is efficacious in the long term with acceptable morbidity and mortality. We believe it is an underutilized procedure for refractory LUTS in MS patients.

OBJECTIVES: To compare the surgical outcomes of men with bladder outlet obstruction (BOO) due to benign prostatic obstruction (BPO) to those with detrusor underactivity (DU) or acontractile detrusor (DA). MATERIALS AND METHODS: This retrospective, IRB approved study included men who underwent BPO surgery for refractory LUTS or urinary retention. Patients were grouped based on videourodynamic (VUDS) findings: 1) men with BOO, 2) men with DU and 3) men with DA. The primary outcome measure was the Patient Global Impression of Improvement (PGII). Secondary outcome measures included uroflow (Qmax), post-void residual volume (PVR) and the need for clean intermittent catheterization (CIC). RESULTS: One hundred and nineteen patients were evaluated: 1) 34 with BOO, 2) 62 with DU and 3) 23 with DA. Subjective success rate (PGII) was highest in the BOO group (97%) and those with DU (98%), while DA patients had a PGII success of 26%, (p<0.0001). After surgery, patients with BOO had the lowest PVR (68.5mL). Fifty-six patients (47%) performed CIC pre-operatively (47% of BOO, 32% of DU and 87% of DA patients). None of the patients in the BOO and DU groups required CIC post operatively compared to16/23 (69%) of patients in the DA group (p<0.0001). CONCLUSIONS: BPO surgery is a viable treatment option in men with presumed BOO and DU while DA is a poor prognostic sign in men who do not void spontaneously pre-operatively.

INTRODUCTION: To develop and validate a lower urinary tract symptom score (LUTSS) as a measure of lower urinary tract symptom (LUTS) severity and a treatment outcome tool in adults. MATERIALS AND METHODS: An expert panel was convened to develop the LUTSS questionnaire. Content validity was achieved by obtaining subject and expert feedback from two prospective drafts. Subjects were divided into three groups: normal, LUTS and overactive bladder (OAB). Questionnaire was administered on two separate occasions within 1-2 weeks. Test-retest reliability, internal consistency, discriminant validity, criterion validity and responsiveness to change were also assessed. RESULTS: The questionnaire contains 14 questions with answers scored on a 5-point Likert scale (0-4). It includes 9 storage, 4 voiding and 1 bother question. One hundred ninety-one patients completed it; 80 males and 111 females, mean age 65 years (range 22-91). Seventy-two had OAB, 91 LUTS without OAB and 28 were normal. Test-retest intraclass correlation was 0.96 and Cronbach's-â¡ was 0.77, indicating strong test-retest reliability and internal consistency, respectively. ANOVA and post-hoc bootstrap-generated adjustments showed significant differences between the three groups (p < 0.001), demonstrating discriminant validity. Responsiveness to change was exhibited by the significant decrease between preop and postop scores and a concurrent patient global impression of improvement (PGI-I) score indicative of symptomatic improvement. CONCLUSION: The 14-question LUTSS is a validated questionnaire that assesses a full range of LUTS in men and women. The ordinal nature of the data with its highly specific description of symptoms makes it ideally suited as a nuanced and comprehensive symptom score and patient reported outcome (PRO) tool.

OBJECTIVES: To develop an economic, practical and readily available animal model for preclinical testing of urethral bulking therapies, as well as to establish feasible experimental methods that allow for complete analysis of hard microparticle bulking agents. METHODS: Alumina ceramic beads suspended in hyaluronic acid were injected into the proximal urethra of 15 female rats under an operating microscope. We assessed overall lower urinary tract function, bulking material intraurethral integrity and local host tissue response over time. Microphotographs were taken during injection and again 6 months postoperatively, before urethral harvest. Urinary flow rate and voiding frequency were assessed before and after injection. At 6 months, the urethra was removed and embedded in resin. Hard tissue sections were cut using a sawing microtome, and processed for histological analysis using scanning electron microscopy, light microscopy and immunohistochemistry. RESULTS: Microphotographs of the urethra showed complete volume retention of the bulking agent at 6 months. There was no significant difference between average urinary frequency and mean urinary flow rate at 1 and 3 months postinjection as compared with baseline. Scanning electron microscopy proved suitable for evaluation of microparticle size and integrity, as well as local tissue remodeling. Light microscopy and immunohistochemistry allowed for evaluation of an inflammatory host tissue reaction to the bulking agent. CONCLUSIONS: The microsurgical injection technique, in vivo physiology and novel hard tissue processing for histology, described in the present study, will allow for future comprehensive preclinical testing of urethral bulking therapy agents containing microparticles made of a hard material.

PURPOSE: We report our experience with the diagnosis and treatment of women with urinary fistula after mid urethral sling surgery. MATERIALS AND METHODS: We retrospectively reviewed the records of patients with urinary fistula secondary to mid urethral sling surgery. Electronic medical records and billing records were searched. We analyzed sling type, presenting symptoms and interval from initial sling surgery to 1) symptom appearance, 2) fistula diagnosis and 3) fistula repair. Symptomatic outcomes were assessed by PGI-I. Surgical outcomes were based on history and examination. RESULTS: We identified 10 women with a mean age of 58 years (range 37 to 70). Mean interval from mid urethral sling surgery to symptom onset, diagnosis and fistula repair was 2, 16 and 18 months, respectively. Mean followup was 26 months (range 4 to 96). There were 1 ureterovaginal, 1 enterovesical, 6 vesicovaginal and 7 urethrovaginal fistulas. Patients presented with stress urinary incontinence (70%), unaware incontinence (50%), overactive bladder (40%), pelvic pain (30%) and voiding symptoms (20%). Nine women underwent fistula repair and 1 underwent continent urinary diversion. A Martius flap was used in 6 of 9 patients, an omental flap and a bladder wall flap were used in 2 each, urethral reconstruction and ureterocolovesicostomy were performed in 1 each and 7 received an autologous pubovaginal sling. Seven patients (78%) underwent successful fistula repair. A successful symptomatic outcome was achieved in 5 of 7 women with stress urinary incontinence, 3 of 5 with unaware incontinence, 3 of 4 with overactive bladder, 2 of 3 with pelvic pain and 2 of 2 with voiding symptoms. CONCLUSIONS: With careful attention to surgical principles and technique, including removal of as much of the adjacent mesh as possible, a successful outcome can be achieved in most patients with a fistula secondary to mid urethral sling surgery.

To critically review recent literature on lower urinary tract symptoms (LUTS) in patients with Parkinson's Disease.A literature search was conducted using the keywords LUTS, urinary symptoms, non-motor, and Parkinson's disease (PD) via the PubMed/Medline search engine. In the literature, we critically examined lower urinary symptoms in Parkinson's patients by analyzing prevalence, pathogenesis, urinary manifestations, pharmacologic trials and interventions, and prior review articles. The data collected ranged from 1986 to the present with an emphasis placed on recent publications.The literature regards LUTS in PD as a major comorbidity, especially with respect to a patient's quality of life. Parkinson's patients experience both storage and voiding difficulties. Storage symptoms, specifically overactive bladder, are markedly worse in patients with PD than in the general population. Surgical management of prostatic obstruction in PD can improve urinary symptoms. Multiple management options exist to alleviate storage LUTS in patients with PD, ranging from behavioral modification to surgery, and vary in efficacy.Lower urinary tract dysfunction in PD may be debilitating. Quality of life can be improved with a multi-pronged diagnosis-specific approach to treatment that takes into consideration a patient's ability to comply with treatment. A stepwise algorithm is presented and may be utilized by clinicians in managing LUTS in Parkinson's patients.

PURPOSE: We report our experience with the diagnosis and treatment of refractory synthetic sling complications in women. MATERIALS AND METHODS: This is a retrospective study of consecutive women with failed treatments for mesh sling complications. Before and after surgery the patients completed validated questionnaires and voiding diaries, and underwent uroflow with post-void residuals, pad test, cystourethroscopy and videourodynamic studies. Treatment was individualized, and results were subdivided into the 2 groups of conditions and symptoms. Outcomes were assessed with the Patient Global Impression of Improvement with success classified as a score of 1, improvement as 2 to 3 and failure as 4 to 7. RESULTS: A total of 47 women 35 to 83 years old (mean 60) had undergone at least 1 prior operation (range 1 to 4) to correct sling complications. Original sling composition was type 1 mesh in 36 patients and types 2 and 3 in 11. Surgical procedures included sling incision, sling excision, urethrolysis, urethral reconstruction, ureteroneocystotomy, cystectomy and urinary diversion, and enterocystoplasty. Median followup was 2 years (range 0.25 to 12, mean 3). Overall a successful outcome was achieved in 34 of 47 patients (72%) after the first salvage surgery. Reasons for failure were multiple for each patient. Of the 13 patients with treatment failure 9 subsequently underwent 14 operations. Success/improvement was achieved in 5 women (56%) after continent urinary diversion (1), continent urinary diversion and cystectomy (1), partial cystectomy and augmentation cystoplasty (1), biological sling and sinus tract excision (1), and vaginal mesh excision (1). CONCLUSIONS: Success after the initial failure of mesh sling complications repair is possible but multiple surgeries may be required. Each symptom should be addressed separately.

PURPOSE: We analyzed the correlation between pad use, as determined by objective pad count, and the severity of urinary incontinence, as measured by pad weight. MATERIALS AND METHODS: We performed a retrospective study of consecutive incontinent patients who wore pads on a daily basis and were instructed to complete a 24-hour pad test. They were told to use the usual pads, change them as usual and place each in a separate plastic bag the day before the scheduled appointment. All pads were weighed and total urine loss was calculated by subtracting dry pad weight from wet pad weight, assuming that a 1 gm weight increase was equivalent to 1 ml of urine loss. The number of pads was correlated to pad weight using the Spearman rank correlation coefficient due to the nonparametric nature of the data. RESULTS: The 116 patients included 51 men 39 to 89 years old (mean age 66) and 65 women 27 to 95 years old (mean age 72). When comparing the number of pads used to the gm of urine lost, the Spearman ρ was 0.26 (p=0.005) in the total cohort, and 0.40 and 0.26 (each p<0.05) in males and females, respectively. CONCLUSIONS: There was little correlation between the number of pads used and the severity of urinary incontinence (r=0.26). These data suggest that pad count should not be used as an objective measure of incontinence severity. Instead, pad weight on a 24-hour pad test should be used.

A consensus statement published in 2011 summarised current research, clinical approaches, and treatment options for nocturia. Since that time, new research has refined our understanding of nocturia in clinically important ways and new evidence has been presented on the efficacy and outcomes of several treatment methods for this underreported, infrequently recognised, and undertreated problem in adults. This paper provides updated guidance to clinicians in light of recent advances in the field.

Aims: Refractory ketamine-induced uropathy (KU) (RKU) has devastating effects on the lower urinary tract leading to ureteral obstruction and even renal failure. The only effective treatment for RKU is major surgical reconstruction or urinary diversion. Nevertheless, there is a paucity of awareness about this destructive condition; the aim of this study is to conduct a narrative systemic review of all surgical outcomes of RKU. Methods: This is an English language literature review of surgical outcomes in KU patients who underwent reconstructive lower urinary tract surgery or urinary diversion through 5 August 2022. Two independent researchers assessed the relevance of each paper and disputes were settled by a third party. In-vitro, animal studies, letters to the editor and papers that did not evaluate surgical outcomes were excluded. Results: Of the 50 763 identified articles, 622 were relevant based on title, 150 based on abstract, but only 23 papers were relevant by content. In all, 875 patients were documented as having KU, of whom 193 (22%) underwent reconstructive surgery. The data were disconcerting, as the apparent rapid progression from the beginning of KU to end-stage bladder was only a 1-year difference of ketamine abuse between those patients who required surgery (4.4 years) and those that did not (3.4 years). Conclusions: The data suggest that the time interval from the beginning of ketamine-induced uropathy to the end-stage bladder may be measured in months, confounding decision making. There is a dearth of literature about KU, and more research is needed to better understand this pathology.
RESUMO
PURPOSE: We describe the diagnosis and treatment of urethral strictures in women. MATERIALS AND METHODS: We retrospectively identified female urethral strictures from 1998 to 2010. Study inclusion criteria were 1) clinical diagnosis of stricture, 2) stricture seen on cystoscopy, 3) urethral obstruction on videourodynamics according to the Blaivas-Groutz nomogram and/or 4) urethral caliber less than 17Fr. Postoperative recurrence was defined by the preoperative criteria. RESULTS: We identified 17 women with a mean age of 62 years (range 32 to 91) with stricture. Stricture was idiopathic in 8 patients, iatrogenic in 6, traumatic in 2 and associated with a urethral diverticulum in 1. Videourodynamics could not be done in 3 women due to complete obliteration of the urethra. Ten of 14 patients satisfied videourodynamic criteria for obstruction and 4 had impaired detrusor contractility. Nine women underwent vaginal flap urethroplasty, including 5 who also had a pubovaginal sling and 1 who had a Martius flap. One patient received a buccal mucosal graft as primary treatment after initial dilation. There was no recurrence at a minimum 1-year followup but 2 strictures recurred 5½ and 6 years postoperatively, respectively. These 2 women received a buccal mucosal graft and were stricture free 12 to 15 months postoperatively. Of 17 patients initially treated with urethral dilation recurrence developed in 16, requiring repeat dilations until urethroplasty was performed. CONCLUSIONS: In select women vaginal flap urethroplasty and buccal mucosal graft have high success rates, including 100% at 1 year and 78% at 5 years. Urethral dilation has a 6% success rate. Long-term followup is mandatory. Treatment should be individualized.

PURPOSE: To validate the Spanish translation of the Overactive Bladder Symptom Score (OABSS) questionnaire. MATERIALS AND METHODS: The OABSS was translated into Spanish (OABSS-S) and back translated. The OABSS-S was self-administered to subjects, following internal IRB and ISPOR Good Practices guidelines. Spanish speaking patients >18 years of age were recruited from primary care clinics. Content validity was achieved by having the first 25 subjects complete the questionnaire in privacy; afterwards they were interviewed and the clarity of each question was discussed with the patient. All subjects recruited, including the first 25, were divided into two groups by the presence of OAB as determined by a previously validated intake question. Subjects completed the OABSS-S in privacy on two occasions within 10 days. Patients were excluded if their symptoms changed between the first and second administration of the questionnaire. Internal consistency was determined with Cronbach's alpha. Test-retest was determined by Spearman's rho. Discriminant validity was assessed between each group using one-way ANOVA and the Tukey post hoc test. RESULTS: One hundred and seventeen of 128 enrolled subjects completed this study (mean age 55; SD 18). Of 117, 74 (63%) were women 29 with OAB and 45 without OAB. There were 43 men (37%), 18 with OAB and 25 without OAB. A high level of consistency was observed among the seven items answered at visit 1 and 2, with a Cronbach's raw alpha statistic of 0.92. No differences in OABSS-S with age or gender were noted. However, subgroup analysis showed patients in the OAB group were significantly older and post-test analysis showed they had higher scores both for each individual question as well as overall symptom severity scores. Spearman's rank order correlation coefficients showed that there was significant difference between the seven items of the OABSS-S; a strong association (Spearman's rho) was also observed between the total seven-item score at visits 1 and 2 for the total score of all subjects r = 0.84, with OAB: r = 0.81, and without OAB: r = 0.83. Comparison of average total scores obtained for all patients at visits 1 and 2 was not significant (10.47 ± 6.53 vs. 11.02 ± 0.66). Discriminant validity testing revealed that there were significant differences in the responses between all diagnostic groups at visits 1 and 2: with OAB versus without OAB; total versus with OAB; total versus without OAB. CONCLUSION: The Spanish version of the OABSS is valid and reliable and will allow health care providers to easily and quickly assess a Spanish-speaking patient's symptoms.

Overactive bladder (OAB) is a clinical symptom complex whose hallmark is the symptom of urinary urgency, usually accompanied by frequency and nocturia, with or without urgency incontinence. Historically, urodynamics (UDS) evaluation has not been recommended in the initial evaluation of OAB, since it is defined primarily by clinical symptoms. As the pathophysiology of the OAB complex has become more clearly elucidated from recent studies, the role of UDS has again become a topic of discussion as a tool that can provide objective data to reflect these new findings. The utility of UDS in the diagnosis and treatment of OAB is still evolving, but in certain clinical scenarios, especially when empiric treatment has failed, it can provide definitive information that can identify associated pathologies and/or alter the treatment course. Herein, we will discuss the current literature regarding use of UDS in OAB patients and offer our own opinions as to its use.

PURPOSE: To assess the frequency with which environmental cues, which might constitute Pavlovian-conditioned stimuli, occur with urgency and leakage symptoms associated with overactive bladder syndrome (OAB). SUBJECTS AND SETTINGS: The sample group comprised 17 adults (13 women and 4 men); their median age was 74.71 years. METHODS: A semistructured interview was conducted with a convenience sample of 17 patients diagnosed with OAB. Patients were interviewed about interoceptive and environmental cues they related to instances of urinary urgency and leakage. Interviews persisted for 6.11 to 59.38 minutes (M = 21.86 minutes) and were conducted by an interviewer who was trained to administer the interview guide. RESULTS: Most respondents associated at least 1 environmental cue with urgency and leakage, respectively. A mean of 6.1 urgency-related and 4.0 leak-related environmental cues were reported. The most commonly reported environmental cues were "on my way to the bathroom" reported by 88% and "opening the front door of my home" reported by 71%. CONCLUSION: These findings support the hypothesis that Pavlovian conditioning plays a role in OAB symptoms and suggest that treatment might be enhanced by inclusion of Pavlovian extinction procedures.

What's known on the subject? and What does the study add? Nocturia is currently defined by the International Continence Society (ICS) as the complaint that an individual has to wake at night one or more times to void. It is, however, an underreported, understudied, and infrequently recognized problem in adults. Many factors may contribute to nocturia which are treatable, yet patients do not seek care or the condition may not be identified by providers. This paper aims to help healthcare providers better serve patients who are experiencing nocturia by summarizing current research, clinical approaches, and treatment options. The results of the conference provide a balanced evaluation of the full treatment armamentarium capable of meeting the needs of patients with the manifold causes of nocturia such as nocturnal polyuria, overactive bladder, or benign prostatic hyperplasia.

AIMS: The Nocturnal Bladder Capacity Index (NBCi) has been reported to be useful in distinguishing between nocturia caused by low bladder capacity and nocturnal polyuria. This paper aims to calculate reference values for NBCi from an asymptomatic population by comparing these with NBCi values from patients with lower urinary tract symptoms (LUTS) to obtain an indication of the sensitivity with which the NBCi detects low nocturnal bladder capacity. This paper also compares the sensitivity of rounded and unrounded calculations of NBCi. METHODS: Computer processed 3-day bladder diaries from 253 asymptomatic volunteers and 184 female patients with LUTS were analyzed. NBCi values were calculated from each diary using rounded and unrounded formulae. 90th and 95th centile NBCi cutoff values were obtained from frequency distributions. RESULTS: NBCi reference values from the asymptomatic group were 1.1 (unrounded) and 0.7 (rounded) for 90th centile, and 1.3 (unrounded) and 1.0 (rounded) for 95th centile. The use of the rounded formula gave identical NBCi values despite a large variation in V(n) /V(max) ratios whereas unrounded NBCis varied continuously with V(n) /V(max) ratios. The unrounded formula found significantly more elevated NBCis in the patient group. CONCLUSION: We suggest that an unrounded NBCi of 1.3 be considered a cutoff point above which reduced nocturnal bladder capacity should be investigated as a cause of nocturia. Rounding the NBCi lead to an underestimation of elevated values in a population of female patients with LUTS.
