Tahseen and Reid (2009) estimated changes in overactive bladder (OAB) symptoms and urge UI in patients undergoing the TOT procedure for SUI and mixed UI. Telephone interviews were conducted using the International Consultation on Incontinence-Female Lower Urinary Tract Symptoms questionnaire, the International Consultation on Incontinence-Overactive Bladder (ICIQ-OAB) questionnaire, and the Verbal Analogue Satisfaction (VeAS) scale. Pre-operative OAB scores were compared with post-operative scores in women with SUI only (group 1), mixed UI with predominant stress leakage (group 2), and mixed UI with predominant urge (group 3). Case notes were reviewed for pre-operative assessment and complications. At median follow-up of 13 months, significant improvement was noted in ICIQ-OAB scores, from a median of 10 (1 to 15) pre-operatively to a median of 3 (0 to 11) post-operatively (p < 0.001). Overall, urge UI was cured in 19 of 44 (43 %) patients, improved in a further 16 (36 %), and was persistent in only 9 (21 %). In group 2 (SUI predominant), urge UI was cured in 10 of 23 (43.5 %) patients, improved in 10 (43.5 %), and persistent in 3 (13 %). In group 3 (urge UI predominant), urge UI was cured in 9 of 21 (43 %) patients, improved in 6 (28.5 %), and persistent in 6 (28.5 %). Post-operative lower urinary tract symptom scores were low in all 3 groups (median 4/48 [0 to 18]). Stress incontinence was cured in 77 %, improved in a further 19 %, and unchanged in 4 %. Median VeAS score was 9 (2 to 10); 21 % (11/52) of participants had low satisfaction scores (less than 8) owing to persistent urge and slow voiding. The authors concluded that marked resolution or improvement (79 %) in urge UI after the TOT procedure was noted, and no case of de novo urge UI was identified. Moreover, the authors noted that it is unclear how to predict who will benefit and remain free of urge following the surgery. Furthermore, they stated that larger outcome studies of TOT with longer follow-up are needed, ideally using standardized, validated assessment tools, focusing on the common problem of mixed UI, with clear reporting criteria, and assessment at baseline and after surgery.
