[Extracorporeal shock-wave lithotripsy in patients with manifestations of urinary tract infection].

The urinary tract infection is very frequent, especially if calculosis of the urinary tract is present. Urinary infection is widespread, and it appears during the year. The people of all ages and both sexes are affected by urinary infection. In the last few years a reliable progress in the understanding and management of urinary tract infection is achieved. Numerous articles published in professional journals are a good proof of it. The urinary tract infection is frequent and is responsible for the use of large quantities of antibiotics which provoke great costs and make other problems. The role of laboratory tests in the diagnosis of infection is predominant. The clinician is completely dependent on his collegue, a bacteriologist, with regard to the results of urine culture. It is known that microorganisms grow better if they have good nourishment. Infections of the urinary tract were always a significant problem. However, over the last few decades, they became, according to some authors, the most frequent bacterial infection in humans, requiring the frequent administration of immunosuppressive agents, corticosteroids and cytostatics; and at the same time a great number of elder people and chronic patients with reduced immunity are involved. Taking into account that significant and insignificant infections of the urinary tract are frequent in nephropathology, particularly in renal and canalicular calculosis, the aim of the study was to point to extracorporeal shock wave lithotripsy without risk of impairment of already existing infections with and without administration of antibiotic and uroantiseptic agents for prophylactic purposes. A group of 5,078 patients with calculosis of the urinary tract was studied. Extracorporeal shock wave lithotripsy was performed in all patients by Siemens lithotriptor Lithostar (Germany). In patients with calculosis of the urinary tract subjected to extracorporeal lithotripsy bacteriuria was regularly followed. A group of 1,836 (36 percent) patients with urinary tract obstruction and 3,242 (64 percent) patients without urinary tract obstruction were treated (Table 1). In 895 (18 percent) patients with urinary tract obstruction infection was serious. In 321 (6 percent) patients without urinary tract infection, serious urinary tract infection was detected (Table 2). The most frequent causes of urinary tract infection are presented in Table 3. Table 4 shows a review of patients to whom antibiotic therapy, prior to extracorporeal lithotripsy, was prescribed. Infection of the urinary tract is responsible for great morbidity. The treatment of any type of urinary tract infection must include the examination of the effect of antibiotic agents. During the treatment of urinary tract infection with calculosis resistant microorganisms are also developed because of repeated administration of antibiotics to patients in health institutions, and especially to patients with ureteral catheters. The treatment of any type of urinary tract infection must include the examination of the effect of antibiotic agents used. The fundamental aims of the treatment of urinary tract infection are: the eradication of causes of infection and concurrent prevention or optimal control of recurrent infection. As long as the patients with urinary tract calculosis are susceptible of permanent infections. It is indispensable to perform sterilization, and thereafter to remove the stone from the urinary tract, because infection of the urinary tract may cause a series of sequelae in the function of the kidney. Frequently the successful urinary sterilization with antibiotic agents cannot be achieved, and consequently, the carrying out of extracorporeal lithotripsy together with administration of antibiotics, is impossible. Good results can be obtained by a combined therapy of antibiotics and extracorporeal lithotripsy in patients with urinary tract calculosis. (ABSTRACT TRUNCATED)
