Prevention of obturator nerve stimulation during transurethral surgery.
The obturator nerve passes in close proximity to the inferolateral bladder wall, bladder neck and lateral prostatic urethra. During a transurethral operation resection in these areas may result in stimulation of the obturator nerve, causing violent adductor contraction and possible inadvertent bladder perforation. ⋯ Local anesthetic blockade of the obturator nerve as it passes through the obturator canal if effective for adductor spasm during spinal anesthesia. We herein describe the anatomy, pharmacology, technique and results of local obturator nerve blockade.

The effect of bladder function on the dynamics of the ureterovesical junction.
Upper tract perfusion studies in suspected ureterovesical junction obstruction should always be performed with measurement of intravesical pressure and with variation in bladder volume. Obstruction observed with increasing bladder volumes may be related to a non-compliant bladder wall, mechanical obstruction at or near the junction itself or a combination of both factors.
