From: Transurethral versus suprapubic catheterization to test urethral function in rats

Experimental design. Rats underwent initial catheterization, followed by leak point pressure (LPP) with simultaneous external urethral sphincter (EUS) electromyography (EMG) testing. After initial transurethral catheterization, the catheter was removed and a suprapubic catheter was placed. After initial suprapubic catheterization, the catheter was shortened and occluded and a transurethral catheter was placed. This was followed by repeated LPP with simultaneous EUS EMG testing.
