Abstract:
Objective To study effects of tethered spinal cord on functions of bladder and urethra. Methods Thirty six patients with tethered spinal cord were evaluated by video urodynamic studies. Filling phase function of bladder was evaluated by compliance of bladder and the presence of vesicoureteral reflux; voiding phase function of bladder was evaluated by maximal detrusor pressure; the synergy between detrusor and external urethral sphincter and continence of urethra were evaluated by voiding study with synchronous X ray image and pressure flow plot. Results 50% patients was diagnosed as detrusor areflexia with low compliance bladder, which was the main type of neurogenic bladder for patients with tethered spinal cord. And 22% was diagnosed as detrusor hyperreflexia. The incidence (83%)of damage of kidney function in patients with detrsusor areflexia and low compliance was significantly higher than patients with detrusor hyperreflexia ( P
