The proportion of misdiagnosis and errors in the treatment of urological diseases holds high, this being particularly true for iatrogenic pathology of the ureter and urinary bladder. The disturbances used to arise in response to traumatic gynecological and proctological surgical interventions and often remained undetected. The traumas are mainly induced by inaccurate use of the instruments and defects in surgical techniques. One of the serious iatrogenic complications is microcystic involvement of the urinary bladder as a result of radiotherapy for cancer. The method proposed by the authors for medical and social rehabilitation of such patients implies the replacement of the affected urinary bladder with isolated intestinal segment providing the recovery of natural uresis. Systemic endotoxinemia, another variant of urologic iatrogenesis, is associated with massive-dose antibiotics and extensive intracavitary operations. Early diagnosis and management of the conditions are supposed an effective protection against endotoxin shock.
