Original Abstract of the Article

Major Research Findings

OnabotulinumtoxinA has been shown to be an effective and well-tolerated treatment for refractory overactive bladder in real-world practice. 12 OnabotulinumtoxinA was also found to be an effective and well-tolerated treatment for overactive bladder (OAB) with urinary incontinence (UI) in randomized clinical trials. 12 However, data on the use of onabotulinumtoxinA in everyday clinical practice is limited. 12 One known side effect of intravesical onabotulinumtoxinA injection for overactive bladder (OAB) is urinary retention requiring clean intermittent catheterization (CIC), which deters patients from choosing this therapy. 25 To improve the therapeutic effect of intravesical onabotulinumtoxinA injection in patients with refractory overactive bladder (OAB), adding an anticholinergic or beta-3 agonist may be beneficial. 2 OnabotulinumtoxinA injection also carries a risk of urinary tract infection (UTI), which may lead to multidrug resistant (MDR) UTI. 16 Furthermore, patients with diabetes mellitus (DM) treated with intravesical onabotulinumtoxinA injection for overactive bladder (OAB) may have increased urinary retention requiring clean intermittent catheterization (CIC). 6 OnabotulinumtoxinA has also been investigated for the treatment of neurogenic detrusor overactivity, and a systematic review and network meta-analysis found that it is a recommended non or minimally invasive treatment option. 5 Finally, an alternative injection paradigm targeting the lower bladder may reduce the need for CIC by maintaining upper bladder function. 3

Benefits and Risks

Benefit Summary

OnabotulinumtoxinA injections may be a suitable treatment option for refractory overactive bladder, potentially alleviating symptoms such as urinary incontinence, frequency, and nocturia. 12 OnabotulinumtoxinA has also been found to be an effective treatment for neurogenic overactive bladder. 19 Additionally, combining onabotulinumtoxinA with other medications may enhance its therapeutic effects. 2

Risk Summary

OnabotulinumtoxinA injections are associated with potential risks such as urinary retention, requiring clean intermittent catheterization (CIC). 25 Additionally, there is a risk of urinary tract infection (UTI), which may lead to multidrug resistant (MDR) UTI. 16 Furthermore, patients with diabetes mellitus (DM) may experience higher rates of urinary retention following onabotulinumtoxinA injections. 6 Finally, maintaining upper bladder function is essential to reduce the need for CIC after onabotulinumtoxinA injections. 3

Comparison Between Studies

Commonalities Between Studies

Multiple studies have demonstrated the effectiveness and safety of onabotulinumtoxinA injections for treating refractory overactive bladder. 12 28 However, they also highlight the potential risks associated with the injections, including urinary retention and urinary tract infections. 25 16

Differences Between Studies

Research has revealed variations in the effectiveness and risks associated with onabotulinumtoxinA injections. 25 3 For instance, the risk of urinary retention after onabotulinumtoxinA injections can differ significantly among patients. 6 Additionally, some studies suggest that combining onabotulinumtoxinA with other medications can enhance therapeutic effects. 2

Consistency and Inconsistencies in Results

Research consistently indicates that onabotulinumtoxinA injections can be an effective and safe treatment option for refractory overactive bladder. 12 However, it's important to acknowledge the potential risks associated with the injections, including urinary retention and urinary tract infections. 25 16 6 These risks can vary depending on individual patient factors.

Considerations for Applying Findings to Real-Life

OnabotulinumtoxinA injections are a potentially effective treatment option for refractory overactive bladder. 12 However, it's crucial to discuss the potential risks, including urinary retention and urinary tract infections, with patients. 25 16 It's particularly important to be mindful of the increased risk of urinary retention in patients with diabetes mellitus. 6 Furthermore, maintaining upper bladder function is essential to minimize the need for clean intermittent catheterization (CIC) after injections. 3

Limitations of Current Research

Further research is needed to fully understand the long-term effectiveness and safety of onabotulinumtoxinA injections. 12 Additionally, the effectiveness of onabotulinumtoxinA injections can vary among patients. 25 More research is required to determine the optimal dosage and administration methods for onabotulinumtoxinA injections.

Future Research Directions

Future research should focus on investigating the long-term effects and safety of onabotulinumtoxinA injections. 12 Studies are also needed to explore methods for enhancing the effectiveness of onabotulinumtoxinA injections and minimizing associated risks. 2 Further research is required to compare the efficacy of onabotulinumtoxinA injections to other treatment modalities for refractory overactive bladder.

Conclusion

OnabotulinumtoxinA injections have the potential to be an effective and safe treatment for refractory overactive bladder. 12 However, it's crucial to carefully consider the potential risks, such as urinary retention and urinary tract infections, before administering the injections. 25 16 6 OnabotulinumtoxinA injections can be a valuable treatment option for patients with refractory overactive bladder, but careful patient selection and risk assessment are essential.
