Summary: | Objective
To assess the efficacy of OnabotulinumtoxinA (BTXA) injections in men with drug‐refractory non‐neurogenic overactive bladder (NNOAB).
Patients and Methods
A total of 43 men received BTXA injections for NNOAB from 2004 to 2012. Patient Global Impression of Improvement (PGI‐I) score was obtained. For men with wet NNOAB, change in number of pads per day was also assessed.
Results
Forty‐three men with a mean age of 69 (range 37–85) received at least one injection. Of the 43 men, 20 (47%) had prior prostate surgery: 11 had radical prostatectomy (RP) and nine had transurethral resection of prostate (TURP). Overall, average PGI‐I score was 2.7. Comparing PGI‐I score in men who had prior prostate surgery with men who have not: 2.6 ± 0.5 vs 2.8 ± 0.5 respectively (average ± 95% CI), P = 0.6. Comparing PGI‐I score in men who had previous TURP with men who had previous RP: PGI‐I score: 3.3 ± 0.8 vs 2.0 ± 0.5 respectively, P < 0.05. Men who had RP experienced a reduction in pad use (from 3.5 ± 1.7 to 1.6 ± 0.9 pads/day, P < 0.05) while this was not the case amongst men who had TURP (from 1.7 ± 1.5 to 1.4 ± 1.5 pads/day, P = 0.4).
Conclusion
Overall, BTXA injection in men with drug‐refractory NNOAB does provide a symptomatic benefit. Amongst men who have had prior prostate surgery, men who have had RP experience a greater benefit than men who have had TURP, both in regards to PGI‐I score and pad use. |
