RESUMEN
Objective To evaluate the efficacy of the suprapubic arch sling(SPARC)in female stress urinary incontinence by video-urodynamic tests.Method From January 2007 to October 2008,video-urodynamic tests,the pad test and ICI-Q-SF had been performed in all patients who received the SPARC before operation and 3,6 months after operation.Results Thirty-two cases of an effective follow-up for 6 to 20 months,31 patients were satisfied with urinary control,1 patient had mild urinary incontinence.Urodynamics:3,6 months after operation the maximum bladder capacity(MCC),residual urine(RU),detrusor pressure at maximum flow rates(Pdet,Qmax)were no statistical differences compared with those before operation(P＞ 0.05),3 months after operation,abdominal leak point pressure(ALPP)difference was statistically significant compared with that before operation(P =0.000),6 months after operation,the maximum urinary flow rate(Qmax),ALPP differences were statistically significant compared with those before operation(P values were 0.003,0.000).Static urethral pressure profile parameters before operation and 3,6 months after operation,the maximum urethral closure pressure(MUCP)was(35.2 ± 20.4),(53.1 ±22.5),(62.3 ± 19.8)cm H2O(1 cm H20 =0.098 kPa),respectively,functional urethral length(FUL)was (3.5 ± 1.3),(3.9 ± 0.9),(4.2 ± 1.1)cm,respectively,6 months after operation,MUCP,FU L differences were statistically significant compared with before operation(P values were 0.000 and 0.002).Conclusion Urodynamic evaluation by image,SPARC is one of the effective methods to treat the female stress urinary incontinence,the image within 6 months of urodynamic evaluation prompt surgery can increase urethral pressure,strengthen the control of urinary function,while no significant effect on bladder function.
