[The efficacy of a tissue adhesive agent (BI 0.022) in urinary tract surgery--application to pyelo- and ureterolithotomy].

To evaluate the effect of a tissue adhesive agent (BI 0.022) on renal pelvic and ureteral surgery, the adhesive was applied for 44 patients with urolithiasis. The conventional suture method was performed in 87 patients as a control. The tissue adhesive is composed of fibrinogen, thrombin, factor XIII, aprotinin and CaCl2. The number of sutures for closure of the incision made on the rental pelvis and the ureter was significantly reduced by the use of the tissue adhesive (p less than 0.01). There was no tendency of increase in urinary leakage following the application of the method in comparison with the control. Furthermore, it was noteworthy that 10 in cases with less than a 1 cm ureteral incision were completely closed by the use of the adhesive agent. This tissue adhesive agent should be valuable for renal pelvic and ureteral surgery as a simple substitute for the conventional suture method.
