METHODS: This is a cross-sectional study assessing LVH using echocardiogram in PD patients. Left ventricular mass index (LVMI) was calculated to determine LVH. Chronic fluid overload (overhydration) was assessed using the body composition monitor, and blood pressure (BP) was measured using 24-h ambulatory BP monitoring.

RESULTS: Thirty-one patients (21 females:10 males, 48.97 ± 14.50 years and dialysis vintage 40.0 ± 28.9 months) were studied. More than two-thirds (77.4 %) were hypertensive, and a third (35.5 %) were diabetic. Baseline data included mean serum albumin (37.34 ± 4.43 g/l), weekly Kt/V (2.02 ± 0.23), residual renal function of 68 (0-880) ml and ultrafiltration of 1,606.9 ± 548.6 ml. Majority of patients (80.6 %) had LVH on echocardiogram with LVMI of 136.5 ± 37.8 g/m(2) and overhydration of 2.23 ± 1.77 l. Average systolic BP, diastolic BP and mean arterial pressure were 141.2 ± 23.3, 90.8 ± 19.7 and 107.6 ± 19.6 mmHg, respectively. Patients with LVH had a lower serum albumin (p = 0.003), were more overhydrated (p = 0.010) and were on higher number of anti-hypertensive agents (p ≤ 0.001). Predictors of LVMI were overhydration (p = 0.002), the presence of diabetes (p = 0.008) and the number of anti-hypertensive agents used (p = 0.026). However, overhydration (p = 0.007) was the main predictor of LVH on multivariate analysis.

PATIENTS AND METHODS: The open, paramedian approach is the commonest technique to insert the 62-cm coiled double-cuffed Tenckhoff peritoneal catheter. All patients with catheters inserted between January 2004 and November 2007 were retrospectively analyzed for demographics and followed for up to 1 month for complications. We excluded patients whose catheters had been anchored to the bladder wall and who underwent concurrent omentectomy or readjustment without removal of a malfunctioning catheter (n = 7). Intravenous cloxacillin was the standard preoperative antibiotic prophylaxis. ♢

RESULTS: Over the 4-year study period, 384 catheters were inserted under local anesthetic into 319 patients [201 women (62.8%); mean age: 49.4 ± 16.7 years (range: 13 - 89 years); 167 (52.2%) with diabetes; 303 (95%) with end-stage renal disease] by 22 different operators. All Tenckhoff catheters were inserted by the general surgical (n = 223) or urology (n = 161) team. There were 29 cases (7.6%) of catheter migration, 22 (5.7%) of catheter obstruction without migration, 24 (6.3%) of exit-site infection, 12 (3.1%) of leak from the main incision, 14 (3.6%) of culture-proven wound infection, 11 (2.9%) post-insertion peritonitis, and 1 (0.3%) hemoperitoneum. No deaths were attributed to surgical mishap. ♢
