Coagulum Pyelolithotomy and Nephrolithotomy / 대한비뇨기과학회지

ABSTRACT

Successful removal of staghorn and multiple renal calculi has been one of the mist difficult tasks that confront the urologists. The operative method for removal of the renal calculi was selected according to the size, number, location and anatomic features of the renal collecting system. We utilized the coagulum to improve the success of the stone removal for last five months. The coagulum material were mixed in a ratio of 5ml cryoprecipitate or 4% fibrinogen 1ml 20 unit /ml human thrombin0.2ml 10% calcium chloride. The results were as follows. 1. The patients were provided by 3 coagulum pyelolithotomy and 6 coagulum nephrolithotomy, of which utilized cryoprecipitate in 7 cases and 4% fibrinogen in 2 for the fibrinogen source. 2. The seven of nine cases(78.2%) were successfully removed without residual stone, but incompletely in two cases(22.2%). 3. Nondemonstrable stone of the preliminary film were removed additionally in one cases(11.1%). 4. As to the complication, meaningless wound infection and dehiscence was observed in only one case. On basis of our experiences, present here a histologic perspectives, methods, cases and its results, in dication and contraindication for coagulum pyelolithotomy and nephrolithotomy.
