BACKGROUND: The organ-preserving partial nephrectomy has increasingly established itself in small unilateral renal tumours (<4 cm) with contralateral healthy kidney and counter gained in recent years in importance. There was found a significantly increased cardiovascular mortality rate and deteriorated quality of life, the more intact kidney tissue has been removed. OBJECTIVES: In the present study, the influence of pre- and perioperative factors on direct postoperative course was examined, including 5-year survival rate and relapse behaviour after open organ-preserving partial nephrectomy in our own collective. MATERIALS AND METHODS: In this retrospective study of 1657 patients were collected, who underwent surgery between 2007 and 2013 in the Department of Urology at the University Hospital Essen because of a renal tumour. 38 % of these operations (n = 636) were performed organ-preserving. In this trial there are factors identified that have an impact on need of blood transfusion and length of hospitalization in organ-preserving operation method. RESULTS: No independent parameter can be determined for the need of blood transfusion. Tumour size and thus time of resection procedure does not affect the need of erythrocytes administration. In addition, the tumour size influences neither the postoperative serum-haemoglobin nor serum-creatinine. Increased patient age and female gender are identified as non-modifiable factors, which cause a longer hospitalisation. Postoperative pain therapy can be considered as a variable size, which does not affect the length of hospital stay. Modifiable factors that increase the overall length of stay, however, are the type of direct postoperative monitoring (ICU vs. anaesthetic recovery room) and the administration of blood transfusions. CONCLUSIONS: There are constant factors, which can be associated with a longer residence time in the framework of an organ-preserving partial nephrectomy. Further there is shown evidence of the independence of the tumour size - in addition to proven good oncological results - of an extension of indication of organ-preserving nephrectomy of tumours > 4 cm.
