Objective:
Studies comparing hand-assisted laparoscopic partial nephrectomy (HALPN) and open partial nephrectomy (OPN) for T1 kidney tumors are scarce. This study investigated the perioperative, functional and oncological outcomes of these methods.
Materials And Methods:
A prospective institutional kidney tumor register was used to identify patients between January 2006 and May 2014 undergoing HALPN (n = 139) or OPN (n = 165) for tumors 7 cm or smaller with non-absolute indication for nephron-sparing surgery. The outcomes were compared using univariate and multivariate statistical methods.
Results:
HALPN and OPN groups were similar with regard to tumor characteristics but HALPN patients were 2 years younger (p = 0.001) and had less comorbidity. Fewer intraoperative complications were encountered in HALPN than in OPN patients (7.2% vs 12.7%, p = 0.043). HALPN patients had less all-grade postoperative 30 day complications than OPN patients (27% vs 41%, p = 0.037), but there was no significant difference in Clavien 3-5 complications. Glomerular filtration rate 3 months after operation was lower in the HALPN than in the OPN group (7.1 ± 12.7% vs 10.0 ± 12.4%, p = 0.054). There was no difference in overall survival or recurrence-free survival during the median follow-up of 35 months.
Conclusions:
HALPN is a feasible method to achieve equal perioperative, functional and oncological outcomes compared to OPN in patients with tumors 7 cm or smaller in diameter.
