The value of cystoscopy and bladder biopsy taken at the time of tension-free vaginal tape insertion

Abstract

SummaryThe primary aim of this study was to determine if a cystoscopy performed at the time of a tension-free vaginal tape (TVT) insertion is useful in finding unexpected pathology. A secondary outcome measure was to assess whether a bladder biopsy and cystoscopy performed during the TVT operation provide useful information about the outcome of surgery. The findings in 100 consecutive women were reviewed. A total of 42 women demonstrated mixed detrusor overactivity (DO) and urodynamic stress incontinence (USI); 32 women had abnormal biopsies. Women with DO were no more likely to have abnormal bladder biopsies than women without DO (p > 0.05). An abnormal bladder biopsy or cystoscopy failed to predict postoperative irritable symptoms (p > 0.05). The presence of preoperative DO correctly predicted postoperative irritable symptoms (p < 0.01). Cystoscopic abnormalities were noted in 14 women including one carcinoma, and one case of dysplasia was discovered on biopsy. In five women, the cystoscopy showed a bladder perforation. Cystoscopy should be performed in all women undergoing continence procedures.
