Abstract

Urinary retention affects millions of people, and is characterized by a weak flow of urine or high post-void residual urine volume in the bladder. In severe neurogenic bladder conditions, such as that resulting from spinal cord injury, sensation from the bladder and voluntary control of micturition are lost. Micturition can be driven by using the sacral anterior root stimulator (SARS). However, commercially available SARS devices are not equipped with a closed-loop regulator for adaptive and automated control of bladder contractions. In this study, we developed a closed-loop control strategy for bladder emptying in a rat model, achieving 86% void efficiency. Our results provide a basis for developing an implantable closed-loop neural prosthesis for treating underactive bladder in the future.
