Abstract:
Objective To compare the safety of laparoscopic live donor nephreetomy(LDN) and open live donor nephrectomy(ODN), evaluate the kidney function and blood pressure of living donors during 1 year follow-up. Methods Thirty cases of LDN and 30 eases of ODN were retrospectively reviewed. The operation time, warm ischemia time, operative blood loss, time to post-operative intake and time to ambulation of the 2 grouups were compared. According to the modified Clavien classifica-tion system procedure-related complications were described and compared. Serum creatinine(SCr) le-vels, blood pressure and 24-h urine protein excretion were measured before nephreetomy and 1 d, 7 d, 3 months, 6 and 12 months after nephrectomy. Glomerular filtration rate (GFR) were measured preo-pratively and at 6 and 12 months postoperatively. These data were statistically analyzed. Results The operation time was (98. 6+13. 6)rain and (96.3+19. 5)rain in the LDN and ODN groups, re- spectively. Warm ischemia time in the LDN group was (90.6±15.1)s, in the ODN group was (86.4±12.3)s. Operative blood loss was (105.2±634.8)ml and (206.3±126.4)ml in the LDN and ODN groups(P<0.01). For the time to post-operative intake and time to ambulation, LDN group was (28.5±2.9)h and (25.8±63.8)h, ODN group was (38.6±63.3)h and (36.5±65.3)h(P<0.01). Perioperative complications rates were 6.6%(2/30) and 23.3%(7/30) for LDN and ODN, respective-ly. SCr was (109.1±7.5), (105.4±69.5), (96.6±10.7), (89.4±11.5), (91.6±69.3)/zmol/L in the LDN group and (107.3±69.6), (103.3±68.4), (95.4±69.1), (90.5±13.6), (90.3±11.7)μmol/L in the ODN group 1 day, 7 days, 3 months, 6 months and 12 months after nephrectomy. The mean GFR of LDN and ODN was 64.7 and 65.8 ml/min at 6 months after nephrectomy, 65.9 and 67.5 ml/min at 12 months postoperatively, which were significantly different comparing with preoperative mean GFR in each group(P<0.05) but no significant difference was found between 6 months and 12 months after nephrectomy and between the 2 groups at the same time point respectively(P>0.05). Mean 24 h protein excretion was elevated after either LDN or ODN during 1 year followup, but was not significantly different either between predonation and 1 year after nephrectomy or between the 2 groups at the same period. Blood pressure increased or decreased slightly with the duration of follow-up,no significant blood presure changes were found before and after nephrectomy or between the two groups at the same period postoperatively. Conclusions LDN has the advantages of minimal trauma, less operative blood loss and quicker convalescence. It is safe and and has no adverse effects regarding kidney function and blood pressure during the first year after living kidney donation comparing to ODN.
