Importance of the creation of a short musculofascial tunnel in peritoneal dialysis catheter placement

Table 1 Comparison of baseline characteristics between the “no-tunnel” and “tunnel” groups¹

	No-tunnel (n = 115)	Tunnel (n = 107)	P value
Age (yr, mean ± SD)	57.03 ± 17.88	58.49 ± 16.38	0.4093
Male, n (%)	64 (55.65)	67 (62.62)	0.3395
BMI (kg/m2, mean ± SD)	23.85 ± 4.27	24.16 ± 4.07	0.5884
Cause of ESRD, n (%)			0.1434
GN	26 (22.61)	23 (21.50)
Polycystic kidney	2 (1.74)	5 (4.67)
Diabetes mellitus	17 (14.78)	26 (24.30)
Others	70 (60.87)	53 (49.52)
History of abdominal surgery, n (%)	22 (19.13)	18 (16.82)	0.7279

¹A two-tailed Fisher’s exact test was used for categorical variables, and a two-tailed unpaired t-test was used for continuous variables.

SD: Standard deviation; ESRD: End-stage renal disease; BMI: body mass index; GN: Glomerulonephritis.
