Sacral rootlet rhizotomy at the conus medullaris for hypertonic neurogenic bladder

Area of Science:

• Neuroscience
• Urology
• Surgical Innovation

Background:

• Spastic neurogenic bladder presents significant challenges in managing urinary dysfunction.
• Current treatments often involve invasive procedures with varying efficacy.

Purpose of the Study:

• To evaluate the efficacy of sacral root stimulation and selective motor rootlet section for spastic neurogenic bladder.
• To compare outcomes with previous rhizotomy techniques.

Main Methods:

• Three patients with spastic neurogenic bladder underwent sacral root stimulation.
• Selective section of motor rootlets to the detrusor was performed at the conus medullaris level.

Main Results:

• Inhibition of urinary frequency and infection was observed for extended periods compared to prior methods.
• Recurrence of uninhibited bladder activity was noted in all three patients.

Conclusions:

• Selective rhizotomy's role in spastic bladder inhibition remains inconclusive.
• Combined surgical and pharmacological approaches may be necessary for long-term urinary system protection.
