Abstract: Stenoza congenitală a uretrei posterioare se întâlnește frecvent și duce la tulburarea întregului tract urinar - uretra suprastenotică, colul vezicii urinare, vezica urinară, ureterohidronefroză, mai frecvent bilateral. Având origine congenitală, această malformație rezultă din dezvoltarea incompletă a membranei urogenitale - limita pasajului uretral posterior și anterior și spasmul muscular al tractului urinar pelvin. Diagnosticul include ultrasonografie, urografie, cistouretrografie micțională, renoscintigrafie dinamică, cistometrie, urofluometrie radionuclidică, uretroscopie, calibrarea uretrei cu buj cu olivă, examen neurologic, miografie musculară perineală. A fost elaboratăt clasificarea clinico-radiologică a acestui tip de stenoze, fiind descrise diferite grade, care necesită un tratament diferențiat în funcție de fazele clinic-radiologice. Stenoza neurogenă se dezvoltă la copiii mai mici cu un tablou clinic mai sever comparativ cel forma congenitală. Rezecția transuretrală a peretelui anterior al uretrei stenotice este metoda de elecție în tratamentul stenozei uretrale.
Congenital posterior urethral stenosis is common and leads to disorder of the entire urinary tract - suprastenotic urethra, bladder neck, bladder, ureterohydronephrosis, more often bilaterally. It can be congenital as a result of incomplete development of the urogenital membrane - the limit of the posterior and anterior urethral passage and the muscular spasm of the pelvic urinary tract. Diagnosis includes ultrasound, urography, micturating cystourethrography, dynamic renoscintigraphy, cystometry, radionuclide uroflowmetry, urethroscopy, calibration of the urethra with olivary bougies, neurological examination, perineal muscle myography. The clinical-radiological classification of stenosis was developed, which is more didactic. There are different degrees of stenosis as suprastenotic resonance that requires a differentiated treatment depending on the clinical radiological phases. Neurogenic stenosis develops in younger children with a more severe clinical picture than the congenital one. Transurethral resection of the anterior wall of the stenotic urethra is the method of choice in the treatment of stenosis.
