[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. In adequate choice of the patients and correct indications combined use of low invasive, endoscopic and open methods provides good treatment effect in patients with IVO and urolithiasis.

[Some current aspects of diagnosis of calculous pyelonephritis].

Immunomicrobiological examination was made of 656 urine and 71 blood samples from 71 patients with chronic pyelonephritis and coral nephrolithiasis. Bacteriuria in blood agar was quantified in colony-forming cells (CFC) in 1 ml of the urine. Identification of the bacterial strains was made by conventional methods. Blood samples were examined for phagocytic activity (PA) of neutrophils and phagocytic index (PI) in incomplete (30 min) and complete (2 hours) variants (S.aureus-209P), levels of IgA, IgM, IgG (in IU/ml), complement (CH50), T- and B-lymphocytes and 0-cells. Opportunistic bacteria (OB) in titer from Ig 2 to Ig 5 CFC/ml and more were identified in 428 (65.25%) samples. OB monocultures prevailed (48.6%). In exacerbation of the disease the majority of the examinees (73.0%) showed deficiency of both cellular and humoral components of antiinfection resistance system (AIRS). First-line defense against bacterial invasion was impaired as shown by incomplete neutrophil digestion in 62.0% of examinees. Among patients with humoral immunodeficiency, those with low IgM were the minority (45.0%). T-RFC and B-RFC deficiency (in 68.0 and 52.0%, respectively), low levels of IgG and IgA (66.0 and 73.0% cases, respectively) indicated deficiency of immunocompetent cells and their functional activity. The study of the AIRS established significance of its components for early and significant diagnosis of calculous pyelonephritis. Pyelonephritis in nephrolithiasis runs with deficiency of both cellular and humoral components of AIRS.
