We request doctors at Beaumont, instead of continuing their clinical trial, to do a historic review on the closely related conventional treatments of neurogenic bladders - denervation and/or detethering, and compare their results to that of those treatments.

Schneidau T, Franco I, Zebold K, Kaplan W. Selective sacral rhizotomy for the management of neurogenic bladders in spina bifida patients: long-term followup. J Urol. 1995 Aug;154(2 Pt 2):766-8.
In 1992, 2 of us (I.F. and W.K.) first reported results with selective sacral rhizotomy and cord untethering in 8 spina bifida patients. We report long-term followup of our original 8 patients and 3 additional patients. This followup demonstrates remarkable success in maintaining bladder volume and low pressures after rhizotomy and cord untethering. Uninhibited contractions resolved in all patients postoperatively. A more favorable response occurred in the patients younger than 9 years, supporting early intervention with selective sacral rhizotomy.
