Trends in kidney transplantation and living donor nephrectomy in Germany: a total population analysis from 2006 to 2021.

ABSTRACT:

Purpose

To analyze recent trends of surgical access routes, length of hospital stay (LOS), and mortality in kidney transplantation (KT) and living donor nephrectomy (LDN) in Germany.

Materials and methods

We studied the nationwide German hospital billing database and the German hospital quality reports from 2006 to 2021.

Results

There were a total of 35.898 KTs. In total, 9044 (25%) were living donor transplantations, while 26.854 (75%) were transplantations after donation after brain death (DBD). The share of open LDN decreased from 82% in 2006 to 22% in 2020 (- 4%/year; p < 0.001). The share of laparoscopic LDN increased from 18% in 2006 to 70% in 2020 (+ 3%/year; p < 0.001). The share of robotic LDN increased from 0% in 2006 to 8% in 2020 (+ 0.6%/year; p < 0.001). Robotic-assisted KT increased from 5 cases in 2016 to 13 procedures in 2019 (p = 0.2). LOS was shorter after living donor KT, i.e., 18 ± 12.1 days versus 21 ± 19.6 days for DBD renal transplantation (p < 0.001). Moreover, LOS differed for open versus laparoscopic versus robotic LDN (9 ± 3.1 vs. 8 ± 2.9 vs. 6 ± 2.6; p = 0.031). The overall in-hospital mortality was 0.16% (n = 5) after LDN, 0.47% (n = 42) after living donor KT and 1.8% (n = 475) after DBD KT.

Conclusions

There is an increasing trend toward minimal-invasive LDN in recent years. Overall, in-hospital mortality was low after KT. However, 5 deceased healthy donors after LKD caution that the risks of this procedure should also be taken very seriously.
