Assessment of the Balloon Dilation Efficiency in Bladder Neck Contracture after Transurethral Interventions on the Prostate

Purpose: The aim was to assess the results of balloon dilation in patients with bladder neck contracture (BNC) after endoscopic surgery for benign prostatic hyperplasia (BPH). Materials and Methods: The study involved 120 patients with recurrent BNC after transurethral interventions for BPH. All patients underwent transurethral resection (TUR) of the bladder neck and were divided into two groups: Group A ( n = 45) included men who, after TUR, additionally underwent repeated balloon dilation, whereas the control group B ( n = 75) included men who were treated with alpha-blockers alone. Results: In 9 months after TUR and 3 months after the 4 th balloon dilation procedure in Group A, the mean international prostate symptom score (IPSS) decreased from 20.1 ± 8.4 to 17.2 ± 7.4, and the IPSS-quality of life was 4.2 ± 1.2 ( P > 0.05). In Group B, they were 21.7 ± 7.7 and 4.7 ± 1.1 ( P > 0.05), respectively. In addition, the mean flow rate in Group A was 13.2 ± 5.4 ml/s, whereas in Group B, it was 8.7 ± 4.9 ml/s ( P < 0.05). There was a significant decrease in the postvoid residual urine volume from 76.2 ± 96.1 ml to 37.6 ± 55.1 ml in Group A, whereas, in Group B, it increased from 63.0 ± 36.9 ml to 79.4 ± 71.6 ml ( P > 0.05). Furthermore, 28.0% of patients of Group B and 13.3% of patients of Group A underwent repeated TUR of the bladder neck in 9 months follow-up period ( P < 0.05). Conclusion: Balloon dilation is a safe less invasive procedure and can reduce the possibility of BNC recurrence and thus the rate of repeated transurethral interventions.
