Comparison of Urologic Complications Between Ureteroneocystostomy and Ureteroureterostomy in Renal Transplant: A Meta-Analysis.

Objectives: Transplant surgeons use a myriad of ureteral anastomotic techniques in renal transplant. Although the Lich-Gregoir extravesical anastomosis is the most common, ureteroureterostomy also is used. In this meta-analysis, our objective was to compare the complication rates of these 2 techniques as reported in the literature.

Biological and electrophysiologic effects of poly(3,4-ethylenedioxythiophene) on regenerating peripheral nerve fibers.

Background: Uninjured peripheral nerves in upper-limb amputees represent attractive sites for connectivity with neuroprostheses because their predictable internal topography allows for precise sorting of motor and sensory signals. The inclusion of poly(3,4-ethylenedioxythiophene) reduces impedance and improves charge transfer at the biotic-abiotic interface. This study evaluates the in vivo performance of poly(3,4-ethylenedioxythiophene)-coated interpositional decellularized nerve grafts across a critical nerve conduction gap, and examines the long-term effects of two different poly(3,4-ethylenedioxythiophene) formulations on regenerating peripheral nerve fibers.

PEDOT electrochemical polymerization improves electrode fidelity and sensitivity.

Background: The goal of the authors is to restore fine motor control and sensation for high-arm amputees. They developed a regenerative peripheral nerve interface with the aim of attaining closed loop neural control by integrating directly with the amputee's residual motor and sensory peripheral nerves. PEDOT, poly(3,4-ethylenedioxythiophene), has both electrical and ionic conduction characteristics.
