[Validation of the Russian version of the ureteral stent symptoms questionnaire (USSQ) for the evaluation of quality of life and stent-related symptoms].

Introduction: Ureteral stents are frequently used in urology practice and have a significant impact on health-related quality of life (QoL). In 2003 . Joshi et al.

[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.

[Ho-YAG laser endoscopic treatment of ureteral strictures].

Ho-YAG-laser radiation with wave length 2.09 microns is a perspective line in high-energy laser treatment of urinary diseases. The authors have performed 24 operations in 23 patients with ureteral strictures.

[The effect of ureteral stents on the peristalsis of the upper urinary tracts].

Ureteral motility changes were followed up in 10 patients with hydronephrosis and urolithiasis which were recorded by multichannel impedance ureterography prior to internal drainage and during stent manipulations. The establishment of the ureteral stents reduces peristaltic amplitude and frequency as well as ureteral tonicity. After the stent removal 20% of the examinees showed peristaltic hyperfunction of the ureter.
