Neurogenic Bladder with Urinary Retention: When Sphincterotomy Has Not Reduced Post-Void Residual Volume or Detrusor Pressure
Clinical Scenario
This protocol targets patients with neurogenic bladder presenting with urinary retention, elevated post-void residual urine volume, and detrusor sphincter dyssynergia — whose previous surgical intervention to facilitate emptying did not achieve its intended goals.
Prior Treatment — Target Goals Not Achieved
External urethral sphincterotomy (with condom catheter drainage), used in appropriately selected male patients to facilitate emptying, did not deliver the required reductions in post-void residual urine volume, maximum detrusor pressure, or detrusor leak point pressure. This failure of the prior line triggers escalation to the current protocol.
Next-Line Approach (Overview Only)
The next-line strategy involves surgical reconstruction — either creating a catheterizable channel to enable controlled bladder drainage, or establishing an intestinal diversion pathway to allow low-pressure urinary outflow. Patient selection criteria, procedural specifics, counselling requirements, and follow-up framework are contained in the full protocol.
