[Occlusive factor in development of urolithiasis complications].

Causes and mechanisms of complications in urolithiasis are analysed with a focus on the role of occlusion of the urinary tracts in the onset of pyoseptic complications. Most severe of them is bacteriotoxic shock which is hard to treat and dangerous for essential body functions. The priority of the treatment must be reestablishment of urine passage. Additional tools of the treatment include wide-spectrum antibiotics, efferent detoxication, electrochemical blood oxidation, hyperbaric oxygenation, UV blood radiation.

[Hyperbaric oxygenation in the treatment of patients with chronic congestive prostatitis and lower fertility].

Due to deteriorated demographic indices in the country, male infertility is a highly pressing problem. Chronic prostatitis is one of its causes. Hyperbaric oxygenation was used to affect male genital microcirculation, thus improving the spermatic morphological and functional characteristics. Positive effects of the method are ascribed not only to better microcirculation, but also to improved redox processes in spermatogenesis.

[Risks and complications of surgical treatment of urinary lithiasis of single kidney].

163 patients with urolithiasis of the solitary kidney were treated surgically. Analysis of causes of postoperative complications (n = 70) and lethal outcomes (n = 11) demonstrate that lethal outcomes were in many cases related to exacerbation of renal failure, acute calculous pyelonephritis which had provoked sepsis and bacteriotoxic shock, acute hemorrhage with hemorrhagic shock followed by development of DIC-syndrome.

[Gastrointestinal hemorrhage in urological diseases].

The authors analyse 28 cases of gastrointestinal hemorrhage (GIH) in urological diseases and after uronephrological operations, emphasize factors of uremic intoxication and relevant complications provoking DIC syndrome. Various factors leading to stress (acute blood loss, shock, sepsis) and development of immunodeficiency disturbed morphostructure of gastric and duodenal mucosa and provoked hemorrhage which was stopped most efficiently by fibrogastroduodenoscopy with coagulation of the bleeding vessel. If this operation failed, open surgery was performed. Conservative measures consisted in DIC syndrome management policy.

[Urinary tract occlusion: a principal cause of some complications of urolithiasis].

Urinary tract occlusion in urolithiasis is a serious complication which provokes an attack of acute obstructive pyelonephritis. The infected urine aggravates this infectious-inflammatory process and endangers bacterial shock. Etiopathogenesis of this shock is outlined and modern approaches to its management are described.

[Bacterial toxic shock in urological diseases].

It is a review of present-day and historical aspects of bacterial toxic shock arising in urological setting. It is noted that conditions of its onset are changing, therapeutic approaches undergo revision, critical care facilities are updated. Among the causes of this complication the authors single out endoscopic procedures, transurethral interventions in the presence of infectious process, hospital infection, long stay at hospital. Forty-eight cases of bacterial toxic shock are reviewed in relation to classification, causes of development, treatment, bacteriological evaluation.

[The effect of psychoemotional stress on kidney function].

Psychoemotional stress, like other kinds of emergency states, is accompanied by renal functional changes and accumulation of biologically active substances in the human body, among which middle molecular oligopeptides are classified. In inadequate or untimely premedication, an operative intervention of any scope occurs initially under unfavourable conditions due to accumulation of biologically active substances in blood and decrease in renal functions. The proposed method of preoperative measurement of the middle molecular oligopeptides and their correlations in plasma and urine may become an indirect indicator of premedication adequacy and a screening test of renal function.

[Epidural anesthesia in urology].

Indications for epidural anesthesia have been analyzed on the basis of 1483 cases of its application. They include transvesical adenomectomy, transurethral electroresection of prostatic adenoma, distant renal and ureteral lithotripsy. It is emphasized that epidural anesthesia is an advantage in older and senile individuals with associated respiratory and circulatory diseases. Epidural anesthesia provides some protection against complications like a transurethral resection syndrome and coagulation disorders. The practical use of epidural anesthesia during urologic operations is safe when its level does not extend above the 9-10th dermatome. A range of measures is offered to prevent complications of epidural anesthesia by stabilizing the hemodynamics and improving blood rheology, coagulation, and humoral status.

[The osmolarity of the blood and urine in patients with tuberculosis of the urinary system and chronic kidney failure].

Osmolarity and its constituents were followed up during the treatment course in 43 patients with tuberculosis of the urinary system and in 14 controls. The authors confirmed the relation of the blood and urinary osmolarity to the stage of chronic renal failure (CRF). CRF aggravation was evidenced by the development of hypo-osmolarity in the urine and a progressing decrease in the ratio coefficient between the osmolarity in the urine and in the plasma. Stability of plasma hyperosmolarity continued to be more than 340 mosmol/kg H2O and a decrease in the aforementioned coefficient to less than 1 despite the treatment evidenced the terminal stage of CRF and unfavourable outcome of surgical intervention.

[The prevention of infectious-inflammatory complications in operations on the kidney].

The paper presented the experience in the prevention of infectious complications during the renal surgery developed both in the organ operated on (acute postsurgical pyelonephritis) and in the surgical wound later. The package of prophylactic measures was employed in 48 patients operated on for the diseases of kidneys and urinary tract (nephrolithiasis predominantly). It included aseptic, antiseptic techniques, antibacterial treatment and preventive treatment in the pre-, intra- and postoperative periods, as well as intraoperative irrigation of the wound with antiseptic solutions and postoperative local therapy. Antibacterial prophylaxis was started 3-5 days or at night before the indicated surgery. Antibiotics were administered only after a careful adjustment of the dosage. Their intravenous (mainly) injections were performed under the effect of preliminary anesthetics. Clinical materials for microbiological and pharmacokinetic monitoring were being taken during the operation. Sodium chloride solution was electrolyzed and the obtained sodium hypochloride was used for the sanation of pyogangrenous foci. Patients with pyodestructive renal lesions developed in the presence of active chronic or acute pyelonephritis and the drainage of the urinary tract underwent 5-7-day antibacterial therapy. The aforementioned preventive measures allowed the authors to gain a significant reduction in the incidence of postoperative pyelonephritis (from 94.2 to 31.2 per cent) and wound infection (from 19.2 to 8.3 per cent), as well as bacteremia (from 32.3 to 5.4). Postsurgical complications (acute pyelonephritis and wound infection), if appeared, ran a relatively favorable course and were cured 3-5 days later. Uroseptic conditions were not observed.
