Posterior urethral polyp in the development of secondary vesicoureteral reflux

Vesicoureteral reflux is a common defect, the essence of which is retrograde throwing of urine from the bladder into the upper urinary tract. Aim - to demonstrate the experience of diagnosis and treatment of posterior urethral polyps on the basis of a clinical case. In the pediatric population, vesicoureteral reflux occurs in 1-2% of children. Cystographic studies conducted in children for various indications revealed the presence of vesicoureteral reflux in 30 % of patients with urinary tract infection and in 17% of children without urinary tract infection. Up to 70% of patients in the first year of life with a history of urinary tract infection have vesicoureteral reflux. It is important that with secondary vesicoureteral reflux, the valves of the ureter may initially be anatomically and functionally capable, but the overloading of the valve mechanism by prolonged (permanent) increased intra-vesical pressure associated with the obstruction leads to distortion of the ureteric-vesicular connection. unity Congenital polyps of the urethra in the pediatric population are a rare, irregular pathology of mesenchymal origin, the exact frequency of which is unknown, they occur more often in the form of benign neoplasms of the posterior urethra among male patients, and usually have a course with the phenomena of obstruction of the lower urinary tract. Until 2004, 181 cases of urethral polyps were registered, and after that period only a few cases of pathology were described in the medical literature. J. Hunter is credited with the first documented case of urethral polyps in a bull (1763), and Thompson was the first to report this pathology in humans in 1855. In 1899, Neuberger first diagnosed a urethral polyp using an endoscope. In the clinical case, the experience of treating a rare pathology - a polyp of the back of the urethra with the help of cystoscopy, which caused secondary vesicoureteral reflux - is given. Conclusions. Polyp of the posterior urethra in pedagogical practice refers to a rare pathology that leads to the development of secondary vesicoureteral reflux. In the treatment of vesicoureteral reflux of the small foot in the presence of a polyp of the posterior urethra, its resection is usually sufficient. In the treatment of vesicoureteral reflux, any STING-type procedure without prior resection of the posterior urethral polyp is not effective. The study was carried out in accordance with the main provisions of the Declaration of Helsinki. The consent of the child's parents was obtained for the study.
