Do bladder neck position and amount of elevation influence the outcome of colposuspension?
1Urogynaecology Unit, Directorate of Obstetrics and Gynaecology, Derriford Hospital, Plymouth, UK.
Objective:
To determine whether the amount of bladder neck elevation and the position of the bladder neck after surgery influence the cure rate after colposuspension.
Design:
Prospective, observational study.
Setting:
Urogynaecology unit, district general hospital.
Population:
Seventy-seven women undergoing colposuspension for urodynamic stress incontinence.
Methods:
The bladder neck was imaged pre-operatively and one week after surgery using magnetic resonance imaging. The position of the bladder neck after surgery and the amount of elevation were correlated to continence outcome one year after surgery (subjective and objective evidence of stress incontinence).
Main Outcome Measures:
Subjective and urodynamic stress incontinence one year after surgery.
Results:
At one year the subjective and objective failure rates were 11.6% and 10.5%, respectively. Measures using magnetic resonance imaging were obtained in 73 women. No association was found between continence outcome and post-operative bladder neck position and elevation.
Conclusion:
The post-operative position of the bladder neck and the amount of elevation do not influence continence outcome. Post-operative morbidity (voiding dysfunction and detrusor instability) might be preventable by avoiding excessive bladder neck elevation and compression, without compromising the success of the procedure.
