Supratrigonal cystectomy with Hautmann pouch as treatment for neurogenic bladder in spinal cord injury patients: long-term functional results.Neurourol Urodyn 2012; 31(5):672-6NU
To study clinical and urodynamic data along with immediate and long-term morbidity of surgical management of neurogenic bladder in spinal cord injury (SCI) patients
Single-center retrospective study of 61 SCI patients with neurogenic detrusor overactivity (NDO) related urinary incontinence and/or sphincter weakness incontinence who underwent supratrigonal cystectomy with Hautmann pouch ± concomitant stress incontinence procedure (27.9%; n = 17).
With a mean follow-up of 5.84 years (range 1-20.5) an improved or total continence rate was achieved in 89.7% and 74.1%, respectively. Surgery failed (incontinence persisted) for six (10.3%) patients, three of which had a simultaneous procedure for stress incontinence. On urodynamics, maximum cystometric capacity (MCC) (ml) increased from 305.2 to 509.4 (P < 0.05), mean compliance (ml/cmH(2) O) increased from 15 to 42.7 (P < 0.05) and mean detrusor pressure at MCC (cmH(2) O) fell from 54.1 to 19.1 (P < 0.05). Persisent NDO occurred in 20.7% compared to 59% pre-operatively (P < 0.05). The overall complication rate was 37.7% but ≤Clavien grade 2 in 82.6%. Notably, the incidence of bowel dysfunction, namely diarrhea and/or fecal incontinence was 27.5%. Concomitant outlet surgery was associated with increased morbidity as three (17.6%) complications led to re-intervention.
Supratrigonal cystectomy with Hautmann pouch is an excellent surgical treatment for SCI patients suffering from refractory NDO incontinence. It achieves the main goals of achieving continence (74% complete), reducing rates of infection and preserving upper tract function, which is reflected in the improvement on urodynamics. The incidence of secondary bowel dysfunction and potential risk of a simultaneous procedure for stress incontinence needs to be discussed.
