AbstractObjectiveTo examine the diagnostic value of hyoid cephalometrics in predicting retroglossal obstruction severity in patients with obstructive sleep apnoea hypopnea syndrome.MethodsNinety-six obstructive sleep apnoea hypopnea syndrome patients diagnosed by polysomnography were recruited. Polysomnography was repeated with a nasopharyngeal tube after eliminating rhinal and palatopharyngeal obstruction. Cervical vertebra lateral films and hyoid cephalometric measurements were obtained, including the distances of the hyoid to the: mental tubercle, prevertebral plane, mental tubercle coronal plane and mental tubercle horizontal plane.ResultsThe apnoea-hypopnoea index for nasopharyngeal tube polysomnography was significantly correlated with distances from the hyoid to: prevertebral plane (r = 0.350), coronal plane (r = 0.477), horizontal plane (r = 0.529) and mental tubercle (r = 0.560). It was strongly correlated with the hyoid to mental tubercle distance/hyoid to prevertebral plane distance value (r = 0.683), and (hyoid to coronal plane distance plus hyoid to horizontal plane distance)/hyoid to prevertebral plane distance value (r = 0.675).ConclusionObstructive sleep apnoea hypopnea syndrome patients with longer hyoid to mental tubercle distances, and/or more inferior and posterior hyoid bone position, are more prone to retroglossal stenosis and obstruction. Hyoid cephalometrics are valuable for predicting retroglossal obstruction severity.

Relevance. Minimally invasive methods of removing the ureteral calculus in urological practice have steadily taken the leading position. According to the Russian clinical recommendations the indications for endoscopic correction of ureteral calculus are concrements with a low probable passage, constant pain symptomatic on the background of adequate analgesia, the varying degrees of obstruction severity and impaired renal function. The purpose of the work is to assess the efficacy of transurethral pneumatic contact lithotripsy of ureteral calculus in emergency urological practice. The research tasks included the refinement of the endoscopic lithotripsy results, depending on the localization level among men and women. Materials and methods. The results of endoscopic treatment of ureteral calculus among 360 patients of both sexes, hospitalized in a urological hospital with emergency indications of a renal colic diagnosis, are presented. Results. The efficiency of retrograde pneumatic contact ureterolithotripsy reached 91.8 %. The most optimal this method is with the localization of calculus in the lower third of the ureter, regardless of the concrement size and sex. The percentage of the calculus fragmentation of the middle third of the ureter among men and women was 91.6 and 93.4 respectively. The lithotripsy in the upper part of the ureter was 23.6 % more effective among women. Operational complications were registered in 7.5 % cases.
