ABSTRACT
Objective:
To assess the clinical result of repeated combined detrusor-trigone botulinum toxin A(BTX-A)injection and intermittent catheterization(IC) for male adults with neurogenic detrusor overactivity (NDO) and urinary incontinence(UI) secondary to spinal cord injury(SCI).Methods:
From January to August 2021, the data of 43 adult male patients with NDO and UI secondary to SCI who received repeated trigone-including intradetrusor BTX-A injection in Guangdong Provincial Work Injury Rehabilitation Hospital were retrospectively analyzed. The mean age of the patients was (29.1±10.7) years. The mean incontinence specific quality of life (I-QOL) was (39±4.8). The UI episodes was (11.9±2.6), mean voiding volume was (170.7±20.1)ml, mean maximum detrusor pressure at first NDO was (81.4±19.6) cmH 2O and mean volume at first NDO was (169.1±40.0)ml.All patients received trigone-including intradetrusor BTX-A (300 U, 30 sites) injection for four times and IC. Clinical data including I-QOL, bladder diary, video-urodynamic test and adverse events were recorded at baseline and 12 weeks after each injection.Results:
Mean interval between four injections were (220.6±27.4), (222.8±24.1) and (224.4±39.0) d ( P=0.13). Compared with baseline data before first injection, mean I-QOL after the first, second, third and fourth injection increased to (54.9±9.1), (56.1±7.9), (61.7±9.1) and (68.8±8.9) (all P<0.001). The number of urinary incontinence cases decreased to 36, 35, 35 and 33 (all P<0.05). The mean urinary incontinence episodes per day decreased to (4.4±0.6), (3.8±0.4), (2.2±0.5) and (2.1±0.3)(all P<0.001). Mean voiding volume increased to (288.3±40.2), (300.0±38.6), (316.9±46.8) and (319.5±36.7) ml (all P<0.001). Mean maximum detrusor pressure at first NDO decreased to (29.4± 11.0), (26.1±8.7), (20.3±5.9) and (18.5±6.0) cmH 2O (all P<0.001) and mean volume at first NDO increased to (270.0±48.7), (284.9±51.3), (287.7±47.9) and (303.0±46.2) ml (all P<0.001), respectively. Compared with four injections, no difference in response was found in the mean I-QOL, the number of urinary incontinence cases, mean urinary incontinence episodes mean voiding volume, mean maximum detrusor pressure at first NDO and mean volume at first NDO (all P>0.05). No de novo VUR occurred and 2 cases of grade Ⅱ VUR at baseline had resolved after the first injection. 9 patients experienced serious gross hematuria within first week after injection, but the urine returned to clear by prolonging the catheter indwelling time or bladder irrigation. 12 patients with active urinary tract infection were treated with indwelling catheter and sensitive antibiotics. Patients continued IC when the symptoms, signs and laboratory examination were normal.Conclusions:
Combined detrusor-trigone BTX-A injection and IC could help decrease detrusor pressure, restore some of the lower urinary tract function and improve the quality of life for male patients with NDO and UI secondary to SCI. Repeated injection is as effective and safe as the first injection.
