|June 1, 1976
Summary
Complete removal of upper urinary tract tumors is crucial. Incomplete nephroureterectomy risks transitional cell carcinoma recurrence in ureteral stumps, highlighting the need for bladder cuff excision.
Area of Science:
- Urology
- Oncology
Background:
- Transitional cell carcinoma (TCC) can affect the upper urinary tract.
- Nephroureterectomy is a standard treatment for upper tract TCC.
Purpose of the Study:
- To review cases of upper urinary tract TCC.
- To evaluate the completeness of nephroureterectomy and its impact on recurrence.
Main Methods:
- Review of 70 cases of transitional cell carcinoma of the upper urinary tract.
- Analysis of surgical technique and recurrence rates.
Main Results:
- Transitional cell carcinoma developed in 30% of remaining ureteral stumps after incomplete nephroureterectomy.
- The intramural ureter was not included in 50% of single-incision nephroureterectomies.
Conclusions:
- Incomplete nephroureterectomy leads to a significant risk of TCC recurrence in ureteral stumps.
- Complete nephroureterectomy, including a bladder cuff, is essential for treating upper tract TCC to prevent recurrence.
