Endoscopic ablation of Hunner's lesions in interstitial cystitis patients.

Introduction: We report our experience with endoscopic ablation of Hunner's lesions in women with interstitial cystitis (IC).

Methods: A chart review was performed on 14 patients with IC symptoms who were identified to have bladder lesions and underwent endoscopic ablation. A Hunner's lesion was identified as an area of erythema that reproduced the patients' pain when touched by the cystoscope.

Hemiparesis of bladder caused by tethered cord.

Conventional teaching has maintained that the detrusor musculature is well-coupled and unilateral innervation should prompt a coordinated detrusor contraction. We present the case of a 17-year-old girl with a tethered spinal cord, unilateral neurologic symptoms and fluoroscopic evidence of ipsilateral hemiparesis of the bladder unresponsive to cord detethering. This adds to a small body of evidence that the bladder smooth muscle is less well-coupled than once believed.
