|January 1, 1987
Summary
Delayed urinary problems after rectal cancer surgery may signal recurrence. Urodynamic evaluation and CT scans can help detect this local pelvic tumor regrowth early.
Area of Science:
- Urology
- Oncology
- Medical Imaging
Background:
- Abdominoperineal resection (APR) for rectal cancer can lead to long-term voiding issues.
- Delayed onset of urinary dysfunction post-APR is often overlooked as a sign of recurrence.
Purpose of the Study:
- To investigate the potential of delayed voiding dysfunction as an early indicator of local pelvic recurrence following APR for rectal cancer.
- To highlight the importance of urodynamic evaluation in diagnosing post-APR voiding abnormalities.
Main Methods:
- Retrospective review of 5 patients presenting with voiding dysfunction 9-24 months after APR.
- Urodynamic evaluation to assess bladder function.
- Computerized tomography (CT) scans to confirm local tumor recurrence.
Main Results:
- Four out of five patients exhibited low bladder wall compliance.
- One patient showed detrusor hyperreflexia.
- CT scans confirmed local tumor recurrence in all 5 cases.
Conclusions:
- Delayed voiding dysfunction following APR for rectal cancer warrants a high index of suspicion for local pelvic recurrence.
- Urodynamic assessment and CT imaging are crucial for diagnosing recurrence in these patients.
