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.

Whereas surgical complications, including vascular occlusion, urine extravasation, drainage obstruction, hematoma, or lymphocele formation, can often be detected effectively, specification of other underlying causes of deterioration of parenchymal function, including acute tubular necrosis (ATN), various types of rejection, and cyclosporine A nephrotoxicity (CyA-NT), frequently cannot be derived independently from the findings of a study without clinical correlation. Besides imaging, plotting of renogram or time/activity curves, numerous quantitative methods have been introduced to provide objective measurements of the blood flow, as well as to gauge the capability of concentration and excretion of the transplanted kidneys. However, the findings whether qualitative or quantitative all have overlapping zones. There is no abnormal image, graphic, or numeric index absolutely specific for any of the possible posttransplant renal parenchymal complications. The differentiation of such conditions may best be achieved through chronologic association of the sequential changes, with or without quantification, detected in serial studies with the clinical presentation and findings.</p>","PeriodicalId":76784,"journal":{"name":"Urologic radiology","volume":"14 2","pages":"115-26"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02926912","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12680068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
