Match each clinical presentation of urothelial carcinoma with its most appropriate definitive surgical or procedural management.
- A 65-year-old man with a 2-cm low-grade papillary tumor confined to the bladder mucosa (Ta)Transurethral resection of bladder tumor with perioperative intravesical chemotherapy
- A 70-year-old woman with high-grade urothelial carcinoma involving the lamina propria (T1) and associated carcinoma in situTransurethral resection of bladder tumor followed by induction and maintenance intravesical Bacillus Calmette-Guérin
- A 68-year-old man with urothelial carcinoma invading the detrusor muscle (T2) with no evidence of metastatic diseaseNeoadjuvant systemic chemotherapy followed by radical cystectomy and pelvic lymph node dissection
- A 72-year-old woman with a large, high-grade urothelial carcinoma located in the right renal pelvisRadical nephroureterectomy with excision of the ipsilateral bladder cuff
Cevap
Each specific stage and anatomical location of urothelial carcinoma requires a distinct surgical approach, ranging from localized transurethral resection to radical extirpative surgery.
The correct pairings accurately reflect standard urologic oncology protocols. Superficial low-grade tumors require local resection and single-dose prophylaxis. High-grade or lamina propria-invasive tumors require aggressive intravesical immunotherapy (BCG) after complete transurethral resection. Muscle-invasive tumors require radical extirpative surgery (cystectomy), typically preceded by systemic chemotherapy. Upper tract tumors necessitate removal of the entire upper urinary unit (nephroureterectomy) to prevent recurrence in the distal ureteral stump.

Surgical management of urothelial carcinoma is dictated by tumor depth of invasion (clinical stage), histologic grade, and anatomic location within the urinary tract.
