Radical surgery of kidney cancer by post-pyelic retrograde free control of renal pedicle / 中国医师进修杂志

ABSTRACT

Objective To explore the effect on radical surgery of kidney cancer by post-pyelic retrograde free control of renal pedicle. Methods The patients with pre-T3a stage kidney cancer were divided into two groups, 50 patients in traditional surgical group (traditional group) and 52 patients in post-pyelic retrograde free control of renal pedicle group(research group). The surgical duration, hemarrhage volume, local tumor recurrence in one year after operation, and distal metastasis rate had been compared between the two groups. Results One hundred and two patients underwent successful operations and had one year of follow-up as scheduled after being discharged from hospital. The traditional group took (130± 37) min for surgical duration, and had (400 ± 306) ml of hemarrhage volume; and the research group took (99 ± 28) min for surgical duration, and had (280 ± 225) ml of hemarrhage volume,there were significant difference between the two groups (P < 0.05). After one year of follow-up, 2% (1/50) of local recurrence rate and 6%(3/50) of distal metastasis rate occurred in the traditional group,and only 2% (1/52) of local recurrence rate and 4% (2/52) of distal metastasis rate happened in the research group. There were no obvious difference between the two groups. Conclusion The radical surgery of kidney cancer by post-pyelic retrograde free control of renal pedicle has such features as easy performance, short surgical duration, less hemarrhage, and can lower the surgical risk, achieve satisfactory efficacy and deserve popularization.
