Urodynamic evaluation after Stamey's bladder neck suspension

ABSTRACT

Between January 1993 and December 1995, eighteen patients were subjected to Stamey's bladder neck suspension at our center, with an overall success rate of 94.4%. All patients had preoperative uroflowmetry, water cystometry and profilometry using water-filled catheters. Resting and stress urethral pressure profiles were recorded at 3, 6, 9 and 12 months postoperatively and then every 6 months thereafter. The mean follow-up was 1 year. Patients in whom surgery was successful were further subdivided into two subgroups [A and B] for the purpose of comparison. Group A included 12 patients who had achieved complete cure and group B 6 patients who showed improvement. Success was assessed both subjectively [through direct questions given on subsequent follow-up visits] and objectively [through doing a stress test at each visit]. It was found that different profilometry variables showed a statistically significant increase in postoperative traces for the successful group in general, and a significant difference existed when comparing the two subgroups
