RESUMEN
The development and widespread implementation of modern endourological procedures for the treatment of benign prostatic hyperplasia (BPH) has led to a significant reduction in postoperative complications, but these interventions are associated to an increase of bladder neck contracture (BNC) rate. Various data on the frequency, pathogenesis, and risk factors for the development of BNC after endourological interventions are presented in the literature review. The prevalence of BNC after transurethral procedures depending on the type of energy used reaches up to 10%. Risk factors of BNC included the presence of chronic prostatitis and urinary tract infections, as well as small volume BPH. The age, cardiovascular diseases, type 2 diabetes, obesity, and a long-term smoking are considered as additional risk factors. A detailed study of the risk factors for BNC will further minimize BNC rate after transurethral procedures, thus improving the quality of life of patients.
