Neuromodulation of the Posterior Tibial Nerve for the Control of Urinary Incontinence

Effects of posterior tibial nerve stimulation (PTNS) on lower urinary tract dysfunction: An umbrella review

BACKGROUND

Lower urinary tract dysfunction (LUTD) is a common, troublesome condition that often negatively affects patients' quality of life. Current literature has long been interested in how posterior tibial nerve stimulation (PTNS) can affect this condition.

AIM

To extensively and systematically explore how PTNS affects LUTD based on the most recent systematic reviews.

METHODS

A systematic search was conducted in PubMed, Scopus, Web of Science, and Embase according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All the systematic reviews, with or without meta-analysis that assessed the effects of PTNS on LUTD were retrieved. The quality of the included studies was assessed using the Joanna Briggs Institute tool, and analysis was conducted using the Comprehensive Meta-Analysis version 3 tool.

RESULTS

From a total of 3077 citations, 20 systematic reviews entered this study, and 13 of them included meta-analysis. The population of studies varied vastly, for instance, some studies included only children or women while other focused on a specific pathology like multiple sclerosis-induced neurogenic LUTD. The majority of included studies reported an overall improvement in LUTD following percutaneous PTNS, although admitting that these results were derived from moderate to low-quality evidence.

CONCLUSION

The findings of this thorough umbrella review showed that the positive benefits of PTNS in treating LUTD are currently supported by low-quality evidence, and it is crucial to interpret them with great care.

Urogenital dysfunction following neurotrauma

PURPOSE OF REVIEW

Trauma affecting the nervous system can have widespread consequences, depending on the location and severity of injury. The sensorimotor and cognitive deficits due to neurotrauma have been studied extensively. Although the overall mortality due to neurotrauma has reduced, the disability and morbidity due to neurotrauma has not significantly reduced and focus on urogenital disturbances in these patients has been limited. This article reviews the limited evidence and scientific literature on this topic.

RECENT FINDINGS

Lower urinary tract symptoms are commonly reported in patients with neurotrauma, both acutely and over the long term. Multiple medical and surgical approaches are available for managing bladder dysfunction in these patients. Sexual dysfunction and changes in sexual behaviour are reported by patients with neurotrauma and are usually multifactorial. Treatment options for sexual dysfunction are available and their management requires a holistic approach.

SUMMARY

Urogenital dysfunction contributes significantly to the overall functional outcome and impaired quality of life in patients with neurotrauma. A better understanding of the mechanisms behind the urogenital abnormalities is needed for efficient management and treatment.
