Evaluation of the lower urinary tract dysfunction at patients with unsatisfactory results operative treatment benign prostatic hyperplasia

The aim of study: to evaluate the reasons of persisting dysuria after operative treatment benign prostatic hyperplasia (BPH). Patients and methods: complex urological evaluation, including urodynamic study, were performed 73 patients (average age 63,4 ± 1,2 years) with persisting lower urinary tract symptoms after operative treatment BPH. Dysuria continued 3,4 ± 0,5 years. Control group consists of 36 BPH patient with absence dysuria after operative treatment BPH. Average age patients of the control group was 64,1 ± 1,2 years. Results: Persisting dysuria after BPH surgery commonly was caused by detrusor pathology: detrusor hyperactivity and impaired contractility. These conditions were diagnosed at 46 (63,0%) and at 26 (35,6%) patients. At 19 (26%) patients based on results urodynamic study were diagnosed this both detrusor hyperactivity and impaired contractility. Infravesical obstruction was less frequent reason for persisting dysuria and was diagnosed at 9 (12,3%) patients. Based on results urodynamic study stress urinary incontinence due to sphincter impairment was diagnosed at 5 incontinent patients and mixed incontinence due to detrusor dysfunction and sphincter impairment was found out at 16 patients. Conclusion: Urodynamic evaluation patients with unsatisfactory results operative treatment BPH allows to find out reason of dysuria, including incontinence. Persisting dysuria was caused by detrusor hyperactivity or/and impaired detrusor contractility at majority patients
