Background:
Femoral motor neuropathy (FMN) induced after kidney transplantation (KT) can injure the patient and graft, and it sometimes can leave sequelae on gait. Nevertheless, the cause of FMN has not been determined. We assessed 5 cases of FMN in an attempt to determine the traits induced after KT.
Methods:
Patient data about general characteristics, immunologic characteristics, operative findings, post-operative status, and FMN characteristics were assessed. A Bookwalter self-retaining retractor was used and quadruple immunosuppression was implemented in all cases.
Results:
Five patients had FMN. Four of the 5 patients were women. The mean body mass index (BMI) was 20.38 ± 1.99 kg/m(2) prior to KT and 19.08 ± 1.98 kg/m(2) after KT. The mean graft-recipient weight ratio was 3.46 ± 0.99 g/kg. There was no case of psoas muscle abscess or hematoma. Motor function recovery was obtained 3 to 313 days after rehabilitation. Immediate graft function was favorable in all patients with no rejection or significant complications.
Conclusions:
FMN after KT may occur in patients with a lower BMI and higher graft-recipient weight ratio. This study was based on only 5 patients, and therefore further studies with a larger population size are necessary.
Insights
Femoral motor neuropathy after kidney transplantation may affect patients with lower BMI and higher graft-recipient weight ratios. Further research is needed to confirm these findings in larger patient groups.
Area of Science:
- Nephrology
- Neurology
- Transplantation Surgery
Background:
- Femoral motor neuropathy (FMN) following kidney transplantation (KT) can negatively impact patients and graft outcomes.
- The etiology of post-KT FMN remains unclear, necessitating further investigation.
- This study aimed to identify characteristics associated with FMN after KT.
Purpose of the Study:
- To investigate the clinical characteristics of femoral motor neuropathy (FMN) occurring after kidney transplantation (KT).
- To identify potential risk factors or patient traits associated with the development of FMN post-KT.
Main Methods:
- Retrospective assessment of 5 patients diagnosed with FMN post-KT.
- Data collected included general, immunologic, operative, and post-operative characteristics, as well as FMN specifics.
- All patients received quadruple immunosuppression and surgical retraction with a Bookwalter device.
Main Results:
- FMN was observed in 5 patients (4 women); mean BMI decreased post-KT.
- The mean graft-recipient weight ratio was 3.46 ± 0.99 g/kg.
- Motor function recovery occurred between 3 and 313 days post-rehabilitation, with favorable graft function and no immediate complications.
Conclusions:
- Lower body mass index (BMI) and higher graft-recipient weight ratio may be associated with FMN after kidney transplantation.
- The findings are based on a small sample size (5 patients), highlighting the need for larger cohort studies.
