Single-centre experience with intradetrusor injection of onabotulinumtoxinA: a retrospective study of the years 2003–2012 in a Danish population

Quality of Life in Female Patients with Overactive Bladder after Botulinum Toxin Treatment

BACKGROUND

Manifestations of OAB can considerably diminish the quality of life. Botulinum toxin has emerged as a valuable treatment option in diseases whose symptoms cannot be controlled adequately with other available therapies. The aim of the present study was to compare the subjective quality of life of patients with OAB before the injection of botulinum toxin and three and six months after the intervention.

METHODS

This study was based on a diagnostic survey with three validated questionnaires, ICIQ-OAB, ICIQ-OABqol, and ICIQ-LUTSqol, and an additional questionnaire developed by the authors to collect sociodemographic characteristics and selected medical data.

RESULTS

This study demonstrated significant differences between pre-treatment scores and those at three and six months post injection. At three and six months after the intervention, mean scores for all three instruments (ICIQ-OAB, ICIQ-OABqol, ICIQ-LUTSqol) were significantly lower than the respective pre-treatment values, implying a significant attenuation of OAB symptoms and their lower impact on the quality of life. However, the severity of OAB symptoms and their impact on the quality of life at six months post intervention were significantly higher than at three months, except for the social interaction domain.

CONCLUSIONS

Botulinum toxin is an effective treatment for OAB.

Definitions of Urinary Tract Infection Used in Interventional Studies Involving Neurourological Patients-A Systematic Review

CONTEXT

Neurourological patients often encounter bacteriuria without any symptoms or may experience symptoms suspicious of urinary tract infections (UTIs). However, there is a lack of guidelines that unequivocally state the definition of UTIs in this specific patient group.

OBJECTIVE

To present all used definitions of UTIs in neurourological patients.

EVIDENCE ACQUISITION

This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Studies were identified by electronic search of Medline, Embase, Cochrane controlled trials databases, and clinicaltrial.gov without a time limitation (last search September 2020) and by screening of reference lists and reviews. The occurrences of the various UTI definitions were counted and the frequencies calculated.

EVIDENCE SYNTHESIS

After screening 7164 abstracts, we included 32 studies enrolling a total of 8488 patients with a neurourological disorder who took part in an interventional clinical study. UTI definitions were heterogeneous. The concordance to predefined definitions was low.

CONCLUSIONS

Interventional clinical studies rarely report specific definitions for UTIs, and both clinical and laboratory criteria used are heterogeneous. A generally accepted UTI definition for neurourological patients is urgently needed.

PATIENT SUMMARY

Patients suffering from neurological disorders often experience symptoms in their lower urinary tract that resemble urinary tract infections. Furthermore, they can have positive urine cultures without symptoms (the so-called asymptomatic bacteriuria). However, clinical studies rarely report specific definitions for urinary tract infections, and when it is done, they are heterogeneous. A generally accepted urinary tract infection definition for neurourological patients is urgently needed. TAKE  HOME MESSAGE: Interventional clinical studies on neurourological patients rarely report specific definitions for urinary tract infections (UTIs), and both clinical and laboratory criteria used are heterogeneous. A generally accepted UTI definition for neurourological patients is urgently needed.

Combination therapy with botulinum toxin and bulking agent-An efficient, sustainable, and safe method to treat elderly women with mixed urinary incontinence

Aims

To evaluate the efficacy, sustainability and safety of combined botulinum toxin and polyacrylamide hydrogel (PAHG) therapy to treat urgency and stress components of therapy‐refractory mixed urinary incontinence (MUI) in an elderly study population.

Methods

Fifty‐five women with therapy‐refractory MUI were treated with botulinum toxin and PAHG in one surgical procedure. Urgency urinary incontinence (UUI) and stress urinary incontinence (SUI) outcomes were separately assessed after 4 and 12 months by objective UUI episodes/24 h and cough test, subjective impact of UUI and SUI on quality of life, and subjective International Consultation on Incontinence Questionnaire‐Urinary Incontinence Short Form (ICIQ‐UI SF). MUI outcome was calculated by combining UUI and SUI outcomes. Complications were monitored throughout the study.

Results

At 4 months, objective cure rates were 73%, 53%, and 42%, and subjective cure rates were 71%, 52%, and 50% for SUI, UUI, and MUI. At 12 months, objective cure rates were 73%, 56%, 50% and subjective cure rates were 78%, 42%, and 40% for SUI, UUI, and MUI. The ICIQ‐UI SF score decreased by 9.0 and 8.7 points after 4 and 12 months. All complications were transient and included 22% clean intermittent catheterization immediately after surgery, 33% postvoid residual volumes >100 ml at 14 days, and 13% symptomatic urinary tract infection within the first postoperative month.

Conclusions

The combination of botulinum toxin and PAHG is effective, sustainable and safe to treat therapy‐refractory MUI, even in an elderly and frail study population. Patients benefit from the short surgical procedure without the need for general anaesthesia or discontinuation of anticoagulation.

OnabotulinumtoxinA (botulinum toxin type A) for the treatment of Japanese patients with overactive bladder and urinary incontinence: Results of single-dose treatment from a phase III, randomized, double-blind, placebo-controlled trial (interim analysis)

OBJECTIVE

To evaluate the efficacy and safety of onabotulinumtoxinA (botulinum toxin type A) 100 U in patients with overactive bladder and urinary incontinence.

METHODS

This was a phase III, randomized, double-blind, placebo-controlled trial in Japanese patients who were inadequately managed with overactive bladder medications (anticholinergics and/or β₃ -adrenergic receptor agonists). Eligible patients were randomized 1:1 to receive a single dose of either onabotulinumtoxinA or placebo into the detrusor muscle (n = 124 each). The primary end-point was the change in the number of daily urinary incontinence episodes at week 12 from baseline. Secondary end-points included volume voided per micturition, other symptomatic measures (urinary urgency incontinence, micturition, urgency and nocturia) and patient-reported outcomes.

RESULTS

In the onabotulinumtoxinA group, there was a significantly greater decrease from baseline in the mean number of daily urinary incontinence episodes compared with the placebo group (2.16; P < 0.001), and significantly greater improvement for all secondary end-points (P < 0.05). Urinary tract infection, dysuria, urinary retention and post-void residual urine volume increased represented adverse events occurring at a higher rate in the onabotulinumtoxinA group. The majority of these were mild or moderate in severity.

CONCLUSIONS

Statistically significant and clinically relevant improvements in symptoms and patient-reported outcomes, and tolerability were seen in patients with overactive bladder and urinary incontinence who had been inadequately managed with overactive bladder medications after using onabotulinumtoxinA.
