Donor Nephrectomy Through Mini-Flank Incision: A Single-Centre Experience Among Nigerian Patients

Background and objective The field of kidney transplantation in sub-Saharan Africa is still in the rudimentary stages. The majority of patients with chronic kidney disease have no access to renal replacement therapy, leading to very high mortality rates. Donor nephrectomy (DN) is an important aspect of kidney transplantation. Over the last two decades, open DN (ODN) has given way to minimally invasive techniques like laparoscopic DN (LDN) and robotic-assisted DN. In this study, we aimed to describe our experience with mini-flank incision donor nephrectomy (MIDN) at a Nigerian renal transplant center. Materials and methods We conducted a retrospective review of all DN cases performed at a single Nigerian kidney transplantation center over a three-year period. Information obtained from these patients was classified into pre-, intra-, and postoperative. The data included sociodemographic characteristics, preoperative preparation, details of intraoperative techniques, and postoperative findings. These were entered into a proforma and analyzed using SPSS Statistics version 21 (IBM Corp., Armonk, NY). Results A total of 230 patients underwent ODN during the study period. The majority of the donors were males (92.8%) with a mean age of 30.83 ±8.43 years. The body mass index (BMI) of most (76.1%) of the donors was within the normal range (18.5-24.9 kg/m(2)). The duration of DNs ranged from 72 to 154 minutes with a mean duration of 130 ±28 minutes. The length of flank incisions ranged from 7.8 to 12 cm with a mean incision length of 10.8 ±1.0 cm. Donors who had MIDN attained satisfactory postoperative pain control with about 90% of them having a BMI of <30 kg/m(2). Oral intake and ambulation were commenced on the first postoperative day, and the cosmetic outcomes were deemed acceptable in over 90% of kidney donors. Conclusion Mini-incision for DN through the flank approach is a suitable alternative to LDN in the developing world where facilities and skills for LDN or robotic nephrectomies are largely unavailable. It offers a short recovery time, early ambulation, and excellent allograft outcomes.
