Benign prostatic hyperplasia is one of the most common urological diseases in men of the older age group. Despite the improvement of the methods of conservative treatment of this disease, often patients with benign prostatic hyperplasia undergo surgical intervention. In the postoperative period, patients after removal of prostate hyperplasia nodes often retain symptoms of the lower urinary tract, which is associated with the peculiarities of the surgical technique and possible infectious complications. Improving the method of surgical treatment of benign prostatic hyperplasia and assessing the risk of possible postoperative complications are important clinical tasks.
Aim: to study the uroflowmetric characteristics of urodynamics by modeling various clinical situations in benign prostatic hyperplasia.
Materials and methods: 3 bladder models created. To create a model of the bladder, 3 plastic hemispheres with a diameter of 15.6 cm, a sphere with a diameter of 7 cm, a funnel with a diameter of 6 cm, silicone tubes from 13 to 20 cm long, 4.5 mm in diameter were used. Models are layouts. Model 1 is used to simulate an obstructive urination model. Model 2 imitates a conditional “prebubble”, the occurrence of which is possible after performing an adenomectomy. Model 3 imitates the state after surgical treatment of benign prostatic hyperplasia without the subsequent formation of prebubble space. 800 ml of physiological saline was poured into the reservoir of the models; the urodynamic characteristics of the fluid flow from each model were studied.
Keywords: benign prostatic hyperplasia, adenomectomy, urodynamics of the lower urinary tract.
