Improvement of the symptoms of lower urinary tract and sexual dysfunction with tadalafil and solifenacin after the treatment of benign prostatic hyperplasia with dutasteride

摘要

BackgroundThe aim of this research is to study the influence of simultaneous taking of tadalafil and solifenacin in standard and double dosage on the lower urinary tract symptoms (LUTS) and sexual dysfunction in men with benign prostatic hyperplasia after the course of dutasteride.Materials and methodsThe research included 326 patients older than 50?years with benign prostatic hyperplasia coupled with LUTS?and sexual dysfunction having undergone the course of treatment with dutasteride. After random division into three groups, patients from the Group A (n?=?107) got tadalafil 5?mg/d?as monotherapy, from the Group В (n?=?107) got tadalafil 5?mg/d and solifenacin 10?mg/d, and from the Group С (n?=?112) got tadalafil 5?mg/d and solifenacin 20?mg/d. The duration of treatment was 12?weeks. The rating of sexual function was made with the questionnaires International Index of Erectile Function and other.ResultsThe results of rating of sexual function with the questionnaires MSHQ-EjD and International Index of Erectile Function correlated among themselves. According to MSHQ-EjD, overall rating of the sexual function increased in each of the three groups (A: 67.9 (12.4)/91.5 (10.4), P?≤?0.05; B: 72.4 (14.5)/102.6 (16.9), P?≤?0.05; C: 76.6 (16.3)/109.6 (15.6), P?≤?0.05). The level of hyperactivity symptoms decreased in Groups В and С (В: urgency??2.9 (0.7)/1.1 (0.6), P?≤?0.05; nocturia 2.7 (1.0)/0.7 (0.5), P?≤?0.05; C: urgency??2.5 (0.5)/0.8 (0.6), P?≤?0.05; nocturia??2.8 (0.6)/1.0 (0.5), P?≤?0.05), and it did not change in the Group A.ConclusionsThe use of tadalafil as monotherapy significantly improves the sexual function but does not affect overactive bladder symptoms. The combination therapy of tadalafil and solifenacin leads to dramatic improvement of sexual function and reversibility of detrusor hyperactivity symptoms.
