[Prevalence of dentition defects among pre-school children of Tver region according to epidemiological study].

Epidemiological dental study of 724 pre-school children in Tver region revealed high prevalence of dentition defects due to premature removal of temporary molars. Dependence of pediatric population need for prosthetic dentistry from regional dental care system staff competence is shown. The date proved the need for standard correction of orthodontists number and broad application of pediatric prosthetics in daily practice.

[Transurethral contact electroimpulse ureteropyelolithotripsy].

Transurethral contact electroimpulse ureteropyelolithotripsy (TCEUT) was conducted in 161 patients aged 18 to 84 years (mean age 47 +/- 14 years) admitted to the urological department of Zhukovsky city hospital in 2006-2009. Female/male proportion 1.4:1.

[Choice of urinary tract drainage in different age groups of patients with urolithiasis].

Retro- and prospective analyses of 802 case histories of patients with nephrostomic drainage (n=272), ureteral catheter (n=27) and ureteral stent (n=503) treated for urolithiasis in the urological department of M.F. Vladimirsky Moscow Region Research Clinical Institute and Zhukovsky city hospital hospitalized in 1995 to 2009 made it possible to develop algorithms of choice of upper urinary tract drainage depending on clinical and laboratory indices.

[Possibilities of transpapillary and laparoscopic methods of choledocholithiasis treatment].

The results of surgical treatment of patients, suffering choledocholithiasis, were adduced. In 493 patients laparoscopic exploration of common biliary duct was accomplished, in 297 of them the choledocholithiasis diagnosis was definitely established while performing laparoscopic cholecystectomy (LCHE); in 136--endoscopic papillosphincterotomy (EPST) was done preoperatively, but the attempts to perform transpapillary lithoextraction and lithotripsy have failed; in 60--a residual choledocholithiasis was noted. In 930 patients EPST and lithoextraction were performed preoperatively and as a second stage--LCHE.

[Diagnosis and treatment of urolithiasis in combination with infravesical obstruction in presenile and senile patients].

The analysis of the results of examination and treatment of 510 urolithiasis patients with organic infravesical obstruction (IVO) treated in the urological clinic of M. F. Vladimirsky Moscow Regional Research Clinical Institute and in the urological department of Zhukovsky city hospital from 1995 to 2009 made it possible to arrive at the following conclusions: the above patients have obstruction symptoms in 100% cases, irritative symptoms--in more than 2/3 of the patients; combined use of low invasive, endoscopic and open methods reestablishes urodynamics of the lower urinary tract in more than 90% patients; the decision on the treatment policy and techniques depends on severity of clinical symptoms caused by IVO and urolithiasis as well as disturbance of upper and lower urinary tract urodynamics.
