Aim of the study: Horseshoe kidney is one of the most common genitourinary system anomalies. The frequency of its occurrence in the whole population is about 0.25%. In the available literature more than 200 cases of such tumor-defect coexistence have been described. Purpose of this study was to present the possibilities of using various methods of surgical treatment of tumors localized in the horseshoe kidney. Material and methods: In the years 2004-2007 five patients were diagnosed and treated for tumors in horseshoe kidneys. Ultrasonography, computed tomography, urography and nuclear magnetic resonance were applied in the diagnosis. During the treatment both open operations and modern methods of treating tumors with a diameter less than 40 mm (nephron sparing) were used. Results: Renal cell carcinoma (RCC) was confirmed in all the patients. Conclusions: Our observations confirm the fact that RCC is the most often diagnosed tumor in horseshoe kidneys. The prognostic factors are the same as in the case of tumors of the kidneys without any abnormalities. The diagnosis is based on applying the modern methods of imaging and in the treatment it is possible to apply the modern, non-invasive methods. [ABSTRACT FROM AUTHOR]

We describe a case of minimally invasive endoscopic technique used in the treatment of a large calculus in the intestinal neobladder. The patient had the intestinal bladder created by means of the Vesica Ileale Padovana (VIP) method because of an invasive urothelial carcinoma. The use of the pneumatic lithotripter, inserted through the urethra into the intestinal neobladder, enabled crushing of the calculus and safe evacuation of the resulting small fragments. The endoscopic technique described enabled avoidance of a technically difficult surgical treatment and allowed for rapid return of the patient to complete health. In our opinion this is the best method of treatment. [ABSTRACT FROM AUTHOR]
