PERCUTANEOUS TRANSRENAL URETERAL OCCLUSION - INDICATION AND TECHNIQUE

Several techniques for achieving palliative ureteral occlusion in cases of underlying malignant diseases are known to exist. We performed nine ureteral occlusions on seven patients, using two different techniques (occlusion by detachable balloon and by "Harzmann Olive"). Initially, complete occlusion of all ureters was attained; in two cases a second occluding intervention had to be carried out after a period of 6 and 14 weeks. Six of seven patients enjoyed a marked improvement of their quality of life after occlusion. Complications were down to a minimum. In comparison with other techniques described in the literature, Harzmann's method seems to be the simplest, as well as the most fully developed one. It may also be recommended for patients in an advanced tumor stage.
