Summary
Urinary tract metastases from renal carcinoma are rare but can occur after nephrectomy. Investigate unexplained hematuria, especially in the ureteric stump, as resection can offer palliation or cure.
Area of Science:
- Urology
- Oncology
- Medical Research
Background:
- Renal carcinoma (kidney cancer) can rarely metastasize to the urinary tract.
- Urinary tract metastases may occur independently of other metastatic sites.
Purpose of the Study:
- To present cases of urinary tract metastases from renal carcinoma.
- To highlight the importance of considering these rare metastases in patients with a history of nephrectomy.
- To emphasize diagnostic considerations for unexplained hematuria.
Main Methods:
- Case series presentation of five patients with urinary tract metastases.
- Review of clinical presentations, metastatic sites, and treatment outcomes.
Main Results:
- Four of five patients had urinary tract metastasis without other spread.
- Presentations included ureteric obstruction and hematuria.
- Metastatic sites involved the ureter, ureteric stump, bladder, and prostatic fossa.
- One patient was diagnosed post-mortem.
Conclusions:
- Urinary tract metastases from renal carcinoma, though rare, should be considered in patients with prior nephrectomy.
- Unexplained hematuria warrants investigation of the ureteric stump.
- Resection of these metastatic lesions can achieve palliation and potentially cure.
