Abstract:
Objective To explore the outcome of modified bladder neck reconstruction in treating the urinary incontinence due to the sphincter dysfunction.Methods Between January 2010 and December 2014,a total of 23 patients,including 16 male and 7 female cases,with incontinence due to sphincter dysfunction had undergone a procedure of modified bladder neck reconstruction.The mean age was 36 years (range 17-61 years).Etiology of incontinence was secondary to pelvic fracture and urethral rupture procedure in 19 patients and other failure procedures in 4 cases.The mean duration of incontinence was 2 years (range 1-5 years).Urodynamic examination was performed in all patients and the mean maximum urethral pressure was 34 cmH2O (range 21-43 cmH2O).The modified bladder neck reconstruction was performed in 23 patients.Under the general anesthesia and vertical bladder incision,triangular mucosal strips,from the bladder neck to ureteral office,were denuded and leaving the central urethral plate,which was 2.0-2.5 cm in width.In order to form a neourethra and bladder neck,the multilayer triangular muscles were sutured interruptedly over a 14-16 F catheter using 2-0 or 3-0 polyglactin.And the anterior wall of the bladder was then closed over the new bladder neck using continuous sutured.Results The 23 patients were followed up for 6 months to 3 years,mean 1.4 years.Continence achieved in 5 patients.Of them,2 patients had difficulty in voiding but corrected by indwelling the catheter for another 2 weeks.Social continence was achieved in 7 patients.Incontinence status was improved in 7 cases and failed in 2 cases.Urodynamic examination was performed in 4 patients and the mean maximum urethral pressure was 64 cmH2O (range 52-72 cmH2O).Conclusions Our study suggested that the modified bladder neck reconstruction was a good procedure for the treatment of urinary incontinence due to sphincter dysfunction,particularly for the incontinence secondary to the traumatic urethral stricture or other operation.
