Table I.

Number of resected lymph nodes during open radical cystectomy (ORC) and laparoscopic radical cystectomy (LRC) are presented as mean ± standard deviation (SD)

	Mean ± SD (left side)	Mean ± SD (right side)	% of patients with positive lymph nodes
ORC, pT2 (n = 27)	4.7 ±2.4	5.4 ±3.1	15
ORC, pT3 (n = 36)	6.1 ±3.9	6.2 ±3.5	47
LRC, pT2 (n = 47)	9.3 ±2.2	9.2 ±1.7	18
LRC, pT3 (n = 4)	7.3 ±1.5	10.5 ±1.5	0

p < 0.0001 for ORC, pT2 vs. LRC, pT2 (left side), p < 0.0001 for ORC, pT2 vs. LRC, pT2 (right side), p = 0.37 for LRC pT2 (right side) vs. LRC, pT2 (left side), p = 0.83 for ORC pT2 (right side) vs. ORC, pT2 (left side). LRC, pT3 was not analysed due to small patient group (n = 4)
