Summary
Urinary retention (UR) after brain tumor surgery is linked to poorer functional status during rehabilitation. However, rehabilitation benefits patients regardless of initial UR, showing significant functional improvements in all cases.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
- Urology
Background:
- Brain tumor surgery can lead to various complications, including urinary retention (UR).
- The impact of initial UR on functional outcomes following neuro-oncological surgery and subsequent rehabilitation requires further investigation.
- Understanding this relationship is crucial for optimizing patient care and recovery trajectories.
Purpose of the Study:
- To compare functional outcomes after rehabilitation in brain tumor patients with and without initial urinary retention (UR).
- To assess the association between initial UR and functional status during and after inpatient rehabilitation.
- To determine the effectiveness of rehabilitation for brain tumor patients irrespective of their initial UR status.
Main Methods:
- Retrospective review of 61 patients operated on for brain tumors between January 2011 and December 2021.
- Data collection included post-void residual (PVR) urine, tumor characteristics, and functional status assessments (MMSE, MBI, FAC, mRS, MI-lower limb, BBS).
- Functional status was re-evaluated 3 weeks post-rehabilitation for a subset of measures (MMSE, FAC, mRS, MI-lower limb).
Main Results:
- Twenty-four patients had initial UR, while 37 did not.
- The UR group presented with significantly worse initial functional status (MMSE, MBI, BBS, FAC, mRS).
- Both groups demonstrated significant functional improvement post-rehabilitation, with no significant difference in the degree of improvement between groups, although the UR group remained with worse scores in MMSE, FAC, mRS, and MI-lower limb.
Conclusions:
- Initial urinary retention (UR) following brain tumor surgery is significantly associated with poorer functional status, both early in rehabilitation and after its completion.
- Standard inpatient rehabilitation is effective in improving functional outcomes for brain tumor patients, regardless of their initial UR status.
- Early identification and management of UR may be beneficial for improving long-term functional recovery in neuro-oncology patients.
