[Problem of biliourolithiasis-does it exist?]

The analysis of 190 case records and 112 clinical cases of the patients with combination of biliary--and urolithiasis (biliourolithiasis-BUL) was carried out. Besides, for proving frequency of combined disease the differential analysis of 2300 case records of urolithiasis and biliary lithiasis separately was carried out as well. It was determined that this combination occurs in 10%. The purposeful, precise definition of complains, anamnesis of the illness, ultrasound and x-ray examination of biliary and urologic system are of paramount importance in timely diagnosis of such combined diseases. Diagnostic and tactic errors committed by surgeons as well as by urologists are often explained by insufficient knowledge of physicians about rather common combination of bilio- and urolithiasis. Among 112 patients 25 were admitted as urgent, the others--according to planned order--with various diagnoses, and their combined pathology was diagnosed at clinic only after purposeful precise examination. Urgent operations on biliary system were carried out in 21 patients. 84 patients underwent elective operations on biliary and urologic system, simultaneous operations of them being carried out in 31 patients. 7 patients due to their severe cardio-vascular disease underwent conservative treatment. Postoperative lethality made up 0.9%. From 190 patients (archives data) 162 have been operated on. Postoperative lethality made up 3.4%. Cost effect of simultaneous combined operations made up 1,168,000 roubles. It is advisable for patients with BUL diseases, taking into account function of the liver and kidney, their organs blood flow, to perform simultaneous of consecutive surgical interventions on biliary as well as on the urologic system which contribute to the well-timed social and professional rehabilitation of the patients.
