A first review: analysis of performed nephrectomy in urology clinic of "Osijek" university hospital in 1994-2004

Aims: To analyze performed nephrectomy in our clinic due to renal cancer diagnosed in our patients, retrospectively and to begin forming Cancer Registry to support future studies and patients follow up. Materials & methods: Data was obtained from patient's history, laboratory findings, imaging procedures, pathologist remarks and ambulance charts to asses survival rates. All patients underwent surgery in our clinic and all procedures were performed by different departments of our hospital. Results: Total of 269 patients were operated for parenchymal renal cancer in given period of time. Of those 114 patients were females and 155 male, with female to male ratio of 1:1, 36. Average age at the time of operation was 61 years, male population slightly older (61, 5 years) than females (60, 5 years).Also we measured size of tumor but classified by type of procedure (simplex or radical nephrectomy), measuring 6, 9 cm (in largest dimension) for radical nephrectomy and 7, 7 cm for simplex nephrectomy. Predominant stage in our patients wasT1, with T3 as second and of those 17% patients presented with distant metastases (M1) at the time of operation. In 91% of our patients clear cell renal cancer was pathological finding with only sporadic finding of other type of tumors such as oncocytoma, sarcoma and some benign forms. In 269 operated patients, clinically significant complications showed in only 10 patients, prolonging hospital treatment or needing intensive treatment, of those with lethal outcomes. Survival rates are also presented classified by type of procedure (simplex/radical). Conclusion: This retrospective study stands as baseline in our attempt to create a Cancer Registry by our department, helping us to choose best and needed treatment for each patient. Also, as said before this is a first review with more to come in future.
