Treatment Response and Complications after Intradetrusor OnabotulinumtoxinA Injection in Male Patients with Idiopathic Overactive Bladder Syndrome.

PURPOSE: We sought to assess the treatment response, complications and treatment continuation after onabotulinumtoxinA injection in male patients. MATERIALS AND METHODS: We performed a retrospective study of men with refractory idiopathic overactive bladder treated with intradetrusor injection of 100 IU onabotulinumtoxinA since 2007 in our department. Patients with previous radical prostatectomy were excluded from analysis. The treatment response was assessed using a treatment benefit scale of 1-greatly improved, 2-improved, 3-not changed and 4-worse after treatment. A treatment benefit scale score of 1 or 2 was considered a treatment response. Complications were classified according to the CD (Clavien-Dindo) classification. Treatment was considered to have continued if at the last visit patients had received an onabotulinumtoxinA injection within the preceding 12 months. We performed univariate and multivariate analyses to assess factors predictive of the treatment response, complications and continuation on treatment. RESULTS: Of the 146 men with a mean ± SD age of 70.1 ± 13.3 years who were included in study 91 (62.3%) reported a response to treatment. A total of 24 complications (16.4%) were detected, including 19 cases (13%) of urinary retention (CD 2), 2 (1.3%) of hematuria (CD 1) and 3 (2%) of urinary infection (CD 2). Followup was more than 12 months in 128 patients, of whom 88 (68.8%) had discontinued treatment by the end of followup. A higher bladder outlet obstruction index was the only factor predicting a lower treatment response rate and a higher complication rate. CONCLUSIONS: Most male patients with idiopathic overactive bladder showed a treatment response after intradetrusor onabotulinumtoxinA injection. However, the majority discontinued treatment. A higher bladder outlet obstruction index was related to a lower treatment response and a higher complication rate.

Long-term follow-up after cystectomy for bladder pain syndrome: pain status, sexual function and quality of life.

PURPOSE: To assess the long-term complications, pain status, sexual function and quality of life after cystectomy for bladder pain syndrome (BPS). METHODS: We retrospectively reviewed functional variables for 35 patients (34 women/1 man, 67 ± 9 years old) who underwent cystectomy due to BPS since 1993 in our department. Cystectomy was offered to patients with BPS refractory to conservative treatments. Six cystectomies with ileal conduit (17.1%) and 29 supratrigonal cystectomies with enterocystoplasty (82.9%) were performed. Prospectively, patients completed questionnaires on pain [BPIC-SS, visual analogue scale (VAS) for pain], health-related quality of life (EQ-5D) and sexual function (FSFI; 2-36), rated satisfaction with surgery (0-10) and reported whether they would undergo the same surgery again. RESULTS: Mean follow-up was 107 ± 83 months. In two (5.7%) patients, pain persisted and in one patient (2.8%) pain recurred after 20 months. Significant improvements in daytime and nighttime frequency and bladder capacity were observed postoperatively. 21 patients completed questionnaires. Mean BPIC-SS was 7.5 ± 8.4, mean VAS score 2.5 ± 2.8. 14 (66.7%) patients reported no problems related to pain on the EQ-5D, similar to our regional reference population. 13 (61.9%) patients had sexual intercourse after surgery, ten of them without pain. Mean FSFI score was 9.5 ± 9. Satisfaction with surgery was 8.8 ± 1.7 and 20 (95.2%) patients would undergo the same surgery again. CONCLUSION: Pain persistence or recurrence after cystectomy for BPS is infrequent. Quality of life related to pain is similar to that in the general population and patients can resume sexual activity without pain.
