Abstract
AIM
For a long time, benign prostatic hyperplasia (BPH) was considered as only cause of lower urinary tract symptoms (LUTS) in elderly men. More than 30% of patients underwent surgery by the age of 80. Unsatisfactory outcome of surgical treatment of BPH are observed in 9-27% of cases. Various irritative symptoms, which are typical for detrusor overactivity, persist especially often. Currently, anticholinergic drug therapy (m-cholinoblockers) is the main treatment for detrusor overactivity. The aim of our study was to assess the effectiveness of m-cholinoblockers for the treatment of persisted LUTS in men with BPH who had undergone transurethral resection of prostate (TURP).
MATERIALS AND METHODS
The study included 60 patients with BPH who underwent TURP. All patients were divided into two groups. In Group 1, anti-inflammatory therapy for 10 days with 1-month follow-up was prescribed. In Group 2, anti-inflammatory therapy was combined with the drug Toviaz for 1 month. Evaluation of the treatment effectiveness was carried out 3-5 days, 14-15 days and 1 month after TURP, respectively and included voiding diary, IPSS score, QOL, uroflowmetry, adverse events and acute urinary retention.
RESULTS
At baseline, in the Group 1 and 2, average urination frequency was 12.6 and 12.7 times per day, the number of urgency episodes was 9.2 and 9.0 times and number of nocturnal voiding episodes was 5,2 and 5.3 times, respectively. The average IPSS score was 19.8 and 19.7 points and Qmax was 6.5 and 6.7 ml/sec, respectively. By the 14th-15th day of therapy, in both groups positive changes were found. There was a significant decrease (p<0.05) in the urination frequency and nocturnal voiding episodes according to voiding diaries, an increase in Qmax and average IPSS and QOL score. The adverse events rate in group 2 was 16.7%. By the 30th day of therapy in the group 1 there were no significant changes. However, in group 2, urination frequency, number of urgency episodes, average IPSS and QOL score decreased to an average of 5.7 times a day, 0.4 times, 1.2 times, 9.3 points and 1.6 points, respectively. Average Qmax increased to 15.5 ml/sec. No adverse events were detected.
CONCLUSION
According to the results of our study, the use of m-cholinoblockers, in particular Fesoterodine (Toviaz), in combination with standard therapy in patients with detrusor overactivity after TURP is reasonable and allows to effectively and safely alleviate irritative symptoms.
