[The role of ureteral function in formulation of indications for endoscopic treatment of neuromuscular dysplasia of the ureters in adults].

Function of the affected ureter was studied with multichannel impedance ureterography in 6 adult patients (age 18-35 years) with neuromuscular ureteral dysplasia (NUD). Of them, 5 patients had compensated ureteral contractility. These patients received endoscopic therapy with Ho-laser consisting of circular ablation of congenital stricture of intramural portion of the ureter. Control examinations (maximal follow-up 6 years) demonstrated a significant stable decrease in dilatation of the upper urinary tracts.
