The diagnostic accuracy of neuromonitoring for detecting postoperative bowel and bladder dysfunction in spinal oncology surgery: a case series.

PURPOSE: Postoperative bowel and bladder dysfunction (BBD) poses a significant risk following surgery of the sacral spinal segments and sacral nerve roots, particularly in neuro-oncology cases. The need for more reliable neuromonitoring techniques to enhance the safety of spine surgery is evident. METHODS: We conducted a case series comprising 60 procedures involving 56 patients, spanning from September 2022 to January 2024. We assessed the diagnostic accuracy of sacral reflexes (bulbocavernosus and external urethral sphincter reflexes) and compared them with transcranial motor evoked potentials (TCMEP) incorporating anal sphincter (AS) and external urethral sphincter (EUS) recordings, as well as spontaneous electromyography (s-EMG) with AS and EUS recordings. RESULTS: Sacral reflexes demonstrated a specificity of 100% in predicting postoperative BBD, with a sensitivity of 73.33%. While sensitivity slightly decreased to 64.71% at the 1-month follow-up, it remained consistently high overall. TCMEP with AS/EUS recordings did not identify any instances of postoperative BBD, whereas s-EMG with AS/EUS recordings showed a sensitivity of 14.29% and a specificity of 97.14%. CONCLUSION: Sacral reflex monitoring emerges as a robust adjunct to routine neuromonitoring, offering surgeons valuable predictive insights to potentially mitigate the occurrence of postoperative BBD.

An analysis of urodynamic parameters in diabetic and nondiabetic women.

OBJECTIVES: Diabetes is highly prevalent worldwide, with an estimated 536 million living with diabetes in 2021, and that number projected to increase to 783 million by 2045. Diabetic bladder dysfunction is thought to affect up to 60%-90% of individuals with diabetes and can significantly impact quality of life. Despite the prevalence of diabetic bladder dysfunction, the exact pathophysiological mechanism, and resulting clinical presentation, remains debated. Our objective was to compare urodynamic parameters between diabetic and nondiabetic women, assessing the impact of various markers of diabetes severity on bladder function. METHODS: A retrospective chart review was conducted on female patients aged 18 and above who underwent urodynamic studies at a single tertiary care university hospital system from 2014 to 2020. Patients were categorized based on diabetes status, and diabetes severity including duration of disease, hemoglobin A1c levels, insulin dependence, and markers of end-organ dysfunction. Urodynamic variables, including compliance, bladder voided efficiency, bladder contractility index, postvoid residual, maximum flow rate, capacity, voided volume, and detrusor overactivity, were assessed by two independent reviewers. Statistical analyses were performed to assess the impact of diabetes and diabetic severity on urodynamic parameters. RESULTS: A total of 652 female patients were included in the study, of which, 152 (23.3%) had diabetes, with an average duration of diagnosis of 82.3 months. Diabetic women were older and had higher body mass index compared to nondiabetic women. Diabetic retinopathy and neuropathy were present in 18% and 54.6% of diabetic patients, respectively. Significant differences in urodynamic parameters were observed between diabetic and nondiabetic women, with diabetic women showing higher rates of detrusor overactivity (p = 0.01), particularly associated with increasing BMI (p = 0.03). However, classic markers of diabetes severity including duration, as well as markers of end-organ damage, showed mixed associations with urodynamic changes. CONCLUSIONS: Despite the prevalence of diabetic bladder dysfunction and its impact on patient quality of life, the exact mechanisms and clinical presentation remain elusive. Our study highlights the significant differences in urodynamic parameters between diabetic and nondiabetic women, emphasizing the need for further research into the relationship between diabetes and diabetic bladder dysfunction.

A rare case of spontaneous bladder wall abscess mimicking bladder tumour in young women.

INTRODUCTION: Abscess of the bladder wall is a rare urological disorder, with a few cases recorded in the literature. The finding of a bladder wall mass via computed tomography (CT) imaging in a visiting patient is the subject of this report. CASE DISCUSSION: A 37-year-old woman with persistent pain in the suprapubic area and lower urinary tract symptoms was examined as a case study. Through a CT scan revealed an inhomogeneous structure in the anteroinferior part of the right bladder. A cystoscopy procedure followed by transurethral resection was performed to remove the mass, which was found to be an abscess. A Foley catheter with irrigation was administered after surgery, and the patient goes home in three days. CONCLUSION: the patient had no symptoms or discomfort in the lower urinary tract after follow-up. Despite the rarity of bladder wall abscesses, cystoscopy can be used to aid diagnosis. Transurethral resection of bladder wall can reduce the mass and eliminate the possibility of malignancy.

Spontaneous rupture of bladder diverticulum with pseudo renal failure:A case report and literature review.

BACKGROUND: Spontaneous or non-traumatic bladder rupture is rare but can be life-threatening. Bladder rupture caused by a diverticulum is extremely rare, with only a few case reports in medical literature. CASE PRESENTATION: We report the case of a 32-year-old woman admitted to hospital complaints of abdominal pain, oliguria and ascites with no history of trauma. Laboratory tests revealed an elevated serum urea nitrogen(UN) level of 33.5 mmol/l and an elevated creatinine levels of 528 umol/l. X-ray cystography confirmed the rupture of a bladder diverticulum. Subsequent transurethral catheterization led to a prompt increase in urinary output, and serum creatinine level returned to 40 umol/l within 48 h. The patient was successfully treated with laparoscopic diverticulectomy. CONCLUSION: Clinicians should maintain a high level of suspicion for urinary bladder rupture in cases presenting with acute lower abdominal pain, urinary difficulties, and oliguria. When acute renal failure, complicated ascites, and an elevated peritoneal fluid creatinine or potassium level exceeding serum levels are observed, intraperitoneal urine leakage should be suspected without delay. This case emphasizes the importance of early diagnosis and intervention in managing this rare but serious condition.

Mullerianosis of the urinary bladder: a case report.

Mullerianosis is a rare, complex, benign tumor most commonly found in the bladder and often mistaken for a neoplastic lesion.  Herein, we report a case of mullerianosis in a 65-year-old woman who presented with an incidental 2 cm bladder mass found on cross-sectional imaging.  A mixed cystic and solid tumor was identified on cystoscopy and a transurethral resection of the suspected tumor was performed with histopathology confirming a final diagnosis of mullerianosis.  While an unusual diagnosis, mullerianosis of the urinary bladder needs to be correctly identified to provide appropriate treatment and avoid misdiagnosis.

Using Urine Biomarkers to Differentiate Bladder Dysfunctions in Women with Sensory Bladder Disorders.

Sensory bladder disorders encompass several distinct conditions with overlapping symptoms, which pose diagnostic challenges. This study aimed to evaluate urine biomarkers for differentiating between various sensory bladder disorders, including non-Hunner's interstitial cystitis (NHIC), detrusor overactivity (DO), hypersensitive bladder (HSB), and urodynamically normal women. A retrospective analysis of 191 women who underwent a videourodynamic study (VUDS) was conducted, with some also receiving cystoscopic hydrodistention to confirm the presence of NHIC. Participants were categorized into four groups: DO (n = 51), HSB (n = 29), NHIC (n = 81), and normal controls (n = 30). The urine levels of inflammatory and oxidative stress biomarkers were measured. The DO patients exhibited elevated IP-10 levels, while the HSB patients had decreased TAC and 8-OHdG levels. The NHIC patients showed lower IL-2 and higher TNF-α levels. A TNF-α ≥ 1.05 effectively identified NHIC, with an AUROC of 0.889, a sensitivity of 98.8%, and a specificity of 81.3%. An IP-10 ≥ 6.31 differentiated DO with an AUROC of 0.695, a sensitivity of 56.8%, and a specificity of 72.3%. An 8-OHdG ≤ 14.705 and a TAC ≤ 528.7 identified HSB with AUROCs of 0.754 and 0.844, respectively. The combination of 8-OHdG and TAC provided an AUROC of 0.853 for HSB. These findings suggest that TNF-α, IP-10, TAC, 8-OHdG, and IL-2 are promising non-invasive biomarkers for distinguishing between these conditions, which may improve diagnosis and management.

Neuropsychiatric Developmental Disorders in Children Are Associated With an Impaired Response to Treatment in Bladder Bowel Dysfunction: A Prospective Multi-Institutional European Observational Study.

PURPOSE: Bladder and bowel dysfunction is a common but underdiagnosed pediatric entity which may represent up to 47% of pediatric urology consults. The objectives of this observational study were to determine functional 1-year outcomes following standard treatment of bladder and bowel dysfunction in both control and neuropsychiatric developmental disorder groups using validated questionnaires, and to perform an initial cost analysis. MATERIALS AND METHODS: This was a prospective observational study conducted across a number of academic European centers (July 2020-November 2022) for new bladder and bowel dysfunction patients. Parents completed a sociodemographic survey, information pertaining to prior neuropsychiatric developmental disorder diagnoses, as well as a number of validated functional scores. RESULTS: A total of 240 patients were recruited. In the control bladder and bowel dysfunction group, the baseline Dysfunctional Voiding Scoring System and Childhood Bladder and Bowel Dysfunction Questionnaire scores were 20% and 17.% lower, respectively, after 1 year compared to the neuropsychiatric developmental disorder group. The change in improvement was diminished for the neuropsychiatric developmental disorder cohort in both Dysfunctional Voiding Scoring System and Childhood Bladder and Bowel Dysfunction Questionnaire scores. The odds ratio of full symptom resolution was 5.7 in the control cohort compared to the neuropsychiatric developmental disorder cohort. A cost analysis on prescribed medications at referral led to a total cost of €32,603.76 (US $35,381.00) in the control group and €37,625.36 (US $40,830.00) in the neuropsychiatric developmental disorder group. CONCLUSIONS: This study demonstrates that pediatric patients with a neuropsychiatric developmental disorder exhibit more severe bladder and bowel dysfunction at baseline and throughout treatment with a lower overall quality of life, as well as 15.4% higher medication costs at referral. It is also important that parents' and caregivers' expectations are managed regarding higher levels of treatment resistance for functional bladder and bowel issues.

Underactive Bladder and Detrusor Underactivity: New Advances and Prospectives.

Underactive bladder (UAB) is a prevalent but under-researched lower urinary tract symptom that typically occurs alongside detrusor underactivity (DU). Unlike UAB, DU is a urodynamic diagnosis which the International Continence Society (ICS) defines as "a contraction of reduced strength and/or duration, resulting in prolonged bladder emptying and/or a failure to achieve complete bladder emptying within a normal time span". Despite the widespread prevalence of UAB/DU, there are significant gaps in our understanding of its pathophysiological mechanisms, diagnosis, and treatment compared with overactive bladder (OAB) and detrusor overactivity (DO). These gaps are such that clinicians regard UAB/DU as an incurable condition. In recent years, the understanding of UAB has increased. The definition of UAB has been clarified, and the diagnostic criteria for DU have been considered more comprehensively. Meanwhile, a number of non-invasive diagnostic methods have also been reported. Clinical trials involving novel drugs, electrical stimulation, and stem cell therapy have shown promising results. Therefore, this review summarizes recent reports on UAB and DU and highlights the latest advances in their diagnosis and treatment.

Unicornuate Uterus with Noncommunicating Rudimentary Horn (Class U4aC0V0/ESHRE/ESGE Classification) and a Communicating Bladder Endometriotic Nodule.

STUDY OBJECTIVE: To describe the diagnostic workup and laparoscopic management of a noncommunicating left uterine rudimentary horn (class U4aC0V0 European Society of Human Reproduction and Embryology/European Society of Gastrointestinal Endoscopy Classification) with communicating endometriotic bladder nodule. DESIGN: Step-by-step description of the surgical treatment. PATIENT: A 33-year-old woman with unicornuate uterus and a left-side noncommunicating rudimentary horn affected by primary infertility, mild dysmenorrhea (visual analog scale score 6), severe catamenial dysuria (visual analog scale score 10), and catamenial hematuria. SETTING: Noncommunicating rudimentary horns are rare Müllerian anomalies present in 20% to 25% of women with a unicornuate uterus. It is associated with severe dysmenorrhea, pelvic pain, subfertility, and poor obstetric outcomes and usually presents with cyclic pelvic pain that starts early after the menarche. Endometriotic bladder nodules are present in 1% to 2% of patients with endometriosis. In the literature, there are no reported cases of noncommunicating rudimentary horn with communicating endometriotic bladder nodules. Surgical excision of the rudimentary horn is the treatment of choice. In our case, the 2-dimensional/3-dimensional ultrasound revealed a right unicornuate uterus with a left noncommunicating rudimentary horn with hematometra. The uterine fundus presented «gamma sign¼ vascularization. In addition, a bladder endometriotic nodule (16 × 15 mm) communicating with hematometra was displayed. Magnetic resonance imaging demonstrated no additional malformations. Diagnostic hysteroscopy revealed a single cervix without vaginal malformation and small right uterine cavity with single tubal ostium. At laparoscopy, using hysteroscopic transillumination, a clear plane of dissection was identified between the rudimentary horn and the uterus confirming the presence of a noncommunicating horn. Evaluation of the abdominal cavity showed bilateral normal adnexa with normal ovaries. Chromopertubation showed a patent right Fallopian tube and obstructed left tube. INTERVENTIONS: A left salpingectomy using bipolar and the ultrasonic energy was performed. The utero-ovarian ligament was transected, and the left ovary was preserved. The left ovary was suspended at the pelvic wall, the retroperitoneum was opened, the ureter was identified, and the left uterine artery was temporary occluded. The left round ligament was transected and the left paravesical space was developed. With a lateromedial approach, we opened the vesicouterine septum to dissect the bladder from the rudimentary horn. The endometriotic bladder nodule was gently detached from the uterine horn with a lateromedial approach. The left uterine artery was coagulated and dissected at level of the cervix. A solution of vasopressin was injected between the uterine horn and the uterus. Resection of the rudimentary horn was performed. The peritoneum was closed. The temporary occlusion of the uterine artery was removed. The specimen was placed in a bag and removed using an extracorporeal tissue extraction technique. CONCLUSION: The late clinical presentation of our patient with only mild dysmenorrhea could be explained by the drainage of the hematometra from the noncommunicating horn into the endometriotic bladder nodule. The bladder symptoms in patients with Müllerian anomalies should be carefully investigated. The laparoscopic removal of rudimentary horn with mobilization of communicating bladder nodule when present is a safe and feasible method to improve symptomatology.

Bladder lesions as incidental findings during transurethral resection of the prostate: prevalence, diagnosis, and pathological findings.

PURPOSE: The purpose of this study was to determine the prevalence of bladder lesions diagnosed during transurethral resection of the prostate (TURP), to identify the associated risk factors, and to correlate the macroscopic descriptions with the pathological findings. METHODS: This was a single-center retrospective case series conducted at a hospital in the city of São Paulo, Brazil. We reviewed the medical and surgical records of patients who underwent TURP between January 2012 and December 2017. RESULTS: The final sample comprised 513 patients, with a mean age of 70.8 years. Bladder lesions were identified during TURP in 109 (21.2%) of the patients, and 90 of those lesions were submitted for pathological examination. The most common macroscopic finding was bullous edema, which was seen in 57 (63.3%) of the 90 lesions examined. The pathological analysis revealed chronic cystitis in 61 lesions (67.8%) and malignant lesions in 16 (17.8%). Of the 57 lesions described as bullous edema, 5 (8.8%) were found to be malignant. CONCLUSIONS: Alterations in the bladder mucosa appear to be more common among elderly patients who use an indwelling urinary catheter for a prolonged period and among patients with recurrent urinary tract infections. In addition, the risk of a bladder lesion being malignant is apparently higher in current and former smokers than in never smokers. Our findings suggest that at-risk patients should undergo biopsy or resection of incidental bladder lesions even if those lesions seem to be benign, due to the low level of agreement between the visual analysis and the pathological examination.

An adaptive randomized clinical trial in interstitial cystitis/bladder pain syndrome evaluating efficacy of ASP3652 and the relationship between disease characteristics and Hunner's lesions.

PURPOSE: The primary purpose of this study was to evaluate the effect of the fatty acid amide hydrolase (FAAH) inhibitor ASP3652 on efficacy and safety in patients with Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS). The secondary purpose was to evaluate phenotyping based on Hunner's lesions (HL). METHODS: In this randomized trial, adult female patients with moderate/severe IC/BPS received 12 weeks of treatment with an oral dose of ASP3652 (50, 150, or 300 mg twice daily) or placebo. A Bayesian model was employed using accumulating data to adjust the randomization probability and to analyze the primary efficacy variable (change from baseline to end of treatment in Mean Daily Pain [MDP; range 0-10]). Study outcomes and patient characteristics of patients with and without HL (HL+ and HL-) were compared. RESULTS: In total, 287 patients were randomized. The 300 mg dose group (n = 97) showed the largest effect, i.e., a mean change from baseline to end of treatment of -1.73 in MDP. However, the mean difference from placebo was 0.02. The probability that this dose was better than placebo was 13.5%. Adverse event incidence was low and similar between study groups. HL+ patients were older and had more severe symptoms than HL-. An association was suggested in HL+ patients between changes in micturition frequency and MDP (R = 0.41 [95% CI 0.18, 0.63]), which was not observed in HL- (R = 0.04 [95% CI -0.16, 0.29]). CONCLUSION: ASP3652 was safe and well tolerated, but did not show efficacy in IC/BPS. The observed differences between HL+ and HL- suggest that IC/BPS diagnosis and treatment may be approached differently in these two phenotypes. TRIAL REGISTRATION: EudraCT number 2011-004555-39, date of registration: 2012-05-07.

Massive bladder inguinal hernia leading to acute urinary retention.

Bladder inguinal hernias are infrequently encountered in clinical practice. When present, the patient's main concern may be urinary difficulties such as retention. Careful history and physical examination will reveal the diagnosis in most cases, however, advanced imaging may be required. Emergent surgical consultation is required and urological consultation may be needed for preoperative planning and assistance. We present a case of a patient with almost complete herniation of bladder into left inguinal canal into the left hemiscrotum.

Cure of Interstitial Cystitis and Non-Ulcerating Hunner's Ulcer by Cardinal/Uterosacral Ligament Repair.

A serendipitous cure in a 73-year-old woman of Hunner's ulcer, urge, nocturia, apical prolapse by a tissue fixation system tensioned minisling (TFS) which reinforced the cardinal, and uterosacral ligaments (USLs) led us to analyse the relationship between Hunner's ulcer and known pain conditions associated with USL laxity. The original intention was to cure the "posterior fornix syndrome" (PFS), uterine prolapse, and associated pain and bladder symptoms by USL repair. A speculum inserted preoperatively into the posterior fornix alleviated pain and urge symptoms, by mechanically supporting USLs. Hunner's ulcer, along with pain and other PFS symptoms were cured by USL repair. The concept of USL laxity causing chronic pelvic pain and bladder problems is not new. It was published in the German literature by Heinrich Martius in 1938 and by Petros in the English literature in 1993. These findings raise important questions. As PFS symptoms are identical with those of interstitial cystitis (IC), are PFS and IC similar conditions? If so, then patients with IC who have a positive speculum test are at least theoretically, potentially curable by USL repair. These questions need to be explored.

Successful Management of Urinary Bladder Clot with Intravesical Tissue Plasminogen Activator Infusion in a Cat.

A 5 yr old male neutered domestic shorthair with intermittent signs of urinary tract obstruction was suspected of having a blood clot in the urinary bladder secondary to trauma. The cat was hospitalized and received standard supportive therapy for urinary tract obstruction with urinary catheterization, with the addition of intravesical saline flushes in an attempt to promote bladder clot lysis. The cat was subsequently discharged after voluntary urination was observed. The cat was represented 28 hr after discharge because of clinical signs consistent with urinary tract obstruction. The cat was hospitalized and intravesical tissue plasminogen activator (tPA) infusions (0.5 mg of tPA in 10 mL of saline with 2 hr dwell time q 8 hr) were administered to break down the bladder clot (2.78 × 4.46 cm). Thirty-two hours after starting tPA, the clot was no longer visible on ultrasound. The cat was discharged with no recurrent symptoms in the subsequent 11 mo. This is the first report of tPA being used for dissolution of bladder clot in a cat. There were no observed complications, suggesting that intravesical instillation of tPA may be a safe and efficacious therapy in cats, similar to the previously reported successes in dogs and humans.

Detrusor contractility in post-menopausal women: Impact of ageing, complaint and urodynamic diagnosis.

INTRODUCTION: Detrusor contractility (DC) can have a considerable impact on the management oflower urinary tract symptoms (LUTS). However, it is currently impossible to predict, based on clinical data alone, which woman has an impaired DC. Our aim was to determine if DC, assessed by projected isovolumetric pressure-1 (PIP1) and VBN contractility parameter k, was associated with age, main complaint, and urodynamic diagnosis in a population of older women. METHODS: Pressure-flow studies of non-neurologic post menopausal women over 65 referred for investigation of LUTS were retrospectively analyzed. Associations between DC indices PIP1 and k, and age, main complaint and urodynamic diagnosis were assessed in univariate analysis. RESULTS: One hundred and ninety women were included (mean age 74.5 years). There was no significant association between detrusor contractility indices and age considered as a continuous or a categorical variable. Urge urinary incontinence was significantly associated with greater detrusor contractility regardless of age. Regarding urodynamic diagnoses, DC was greater when bladder outlet obstruction and detrusor overactivity were diagnoses vs. detrusor underactivity alone or associated with detrusor overactivity, regardless of age. CONCLUSION: PIP1 and k indices allow an easy evaluation of detrusor contractility. In that population of older, post menopausal women, no significant change in the value of the indices is observed with aging whatever the complaint or the urodynamic diagnosis. None of these indices has predominance. LEVEL OF EVIDENCE: 4.

Transition from childhood to adolescence: steps to be taken.

PURPOSE OF REVIEW: The aim of this article is to give an overview of recent literature on transitional care of children with complex urological disease. RECENT FINDINGS: Most studies on transitional care concerned spina bifida patients. Assessment of current practices revealed that formalized clinics for transitional care may improve healthcare. However, there is still little consensus among healthcare providers on how to organize transitional care. A widely recognized problem is a lack of interested, dedicated, and well-trained staff for transitional care and lifelong follow-up of complex urological patients and also a lack of funding. The timing of the pediatric urologist's transfer to adult care may be helped by measuring transitional readiness in adolescent patients. Outcomes could also expose specific issues as were patients need assistance or education. Introduction of a transitional protocol made patients feel more ready for transition. However, even in established transitional clinics, there is a lack of disease-specific awareness of sexuality and fertility issues among patients. SUMMARY: Although there is growing awareness of the importance of well-organized and protocolled transitional care for young patients with complex urological disease, this is by no means sufficiently implemented. Furthermore, there is shortage of dedicated and experienced healthcare providers and a lack of funding.

Can we improve our diagnosis of impaired detrusor contractility in women? An ICI-RS 2019 proposal.

INTRODUCTION: Widely accepted consensus terminology and calculations of detrusor contractility in females do not exist but may be useful. We report the output of a proposal session at the International Consultation on Incontinence Research Society meeting 2019, addressing the title topic. METHODS: Three formal presentations and a lively discussion addressed several questions including: which is the optimal cutoff value of female bladder voiding efficiency during uroflow to suspect obstruction or detrusor underactivity? Is there a definition of pure underactive and pure obstructed voiding in females? Is there a place to distinguish those relatively obstructed from those relatively underactive females especially in those cases of equivocal obstruction? Current measures of contractility were reviewed for their usefulness in women. RESULTS: No recommendation for a specific index or calculation can be made based on current knowledge. "Contractility" may be context-dependent regarding clinical care, clinical prognostication, and physiologic research. CONCLUSIONS: This group proposes that context-sensitive definitions of "Contractility" deserve attention by international leadership. Cooperative clinical and physiologic expertise will be needed to achieve this goal. Following initial recommendations based on expert opinion, the development of final definitions and measures of contractility should be iterative, based upon validation studies to be considered as part of the definitional process.

Clinical associations with telomere length in chronic spinal cord injury.

STUDY DESIGN: Cross-sectional study OBJECTIVES: To determine clinical factors associated with telomere length in persons with chronic spinal cord injury (SCI). SETTING: Veterans Affairs Medical Center, Boston, MA. METHODS: Two hundred seventy-eight participants with chronic SCI provided blood samples for measurement of C-reactive protein (CRP), interleukin-6 (IL-6), and telomere length, completed respiratory health questionnaires, underwent dual X-ray absorptiometry (DXA) to assess body fat, and completed spirometry. High-throughput real-time PCR assays were used to assess telomere length in leukocyte genomic DNA. Linear regression models were used to assess cross-sectional associations with telomere length. RESULTS: Telomere length was inversely related to age (p < 0.0001). In age-adjusted models, gender, race, injury duration, %-total and %-trunk fat, body mass index (BMI), %-predicted forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1), chronic cough or phlegm, CRP, IL-6, wheeze, smoking, diabetes, heart disease, chronic obstructive pulmonary disease (COPD), skin ulcer, urinary tract infection (UTI), or chest illness history were not significantly associated with telomere length. There was a suggestive age-adjusted association between persons with the most severe SCI (cervical motor complete and AIS C) and shorter telomere length (p = 0.055), an effect equivalent to ~8.4 years of premature aging. There were similar age-adjusted associations with telomere length between persons using a wheelchair (p = 0.059) and persons with chronic urinary catheter use (p = 0.082) compared to persons without these characteristics. CONCLUSIONS: Our results suggest that clinical characteristics such as decreased mobility and bladder dysfunction that are common in individuals with more severe SCI are associated with shorter telomere length.

Immunoglobulin G4-Related Disease Arising from the Bladder Wall.

Immunoglobulin G4-related disease (IgG4-RD) is a recently described inflammatory disease with multiorgan involvement. Although there were reports of IgG4-related kidney disease or prostatitis, this disease rarely presents in the bladder. In this report, we describe a case of IgG4-RD arising from bladder wall. This patient had a past history of autoimmune pancreatitis and presented with incidental bladder tumor. Magnetic resonance imaging showed low signal intensity tumor on T2-weighted image, and no invasion to the muscular layer. We performed transurethral resection. Pathological findings showed that there were chronic inflammatory changes infiltrates under the epithelium, and IgG4-positive plasma cells were scattered throughout the lesion. They met the pathological diagnostic criteria for IgG4-RD. We think this is the first case of IgG4-RD arising from and confined to the inside of the bladder wall.
