Urothelial carcinoma (UC) is a common malignancy of the urinary system that can occur anywhere from the renal pelvis to the proximal urethra. Most UCs are in the bladder and have multifocal growth. Upper urinary tract UC (UTUC), which occurs in the renal pelvis or ureter, accounts for only 5% to 10% of UCs.
In March 2015, a 70-year-old male who initially presented to a local hospital with a complaint of painless hematuria was diagnosed with UTUC of the right renal pelvis. The doctors administered radical nephroureterectomy and bladder cuff excision. Although the doctors recommended intravesical chemotherapy and regular follow-up, he rejected this advice. In December 2016, the patient presented at our hospital with dysuria. We identified UC in the residual bladder and administered radical cystectomy and left cutaneous ureterostomy. In November 2021, he presented again with urethral bleeding. We detected urethral UC as the cause of urethral orifice bleeding and administered radical urethrectomy. Since then, he has visited regularly for 6-mo follow-ups, and was in stable condition as of December 2022.
UTUC is prone to seeding and recurrence. Adjuvant instillation therapy and intense surveillance are crucial for these patients.
Core Tip: Urothelial carcinoma (UC) is a common malignancy in the urinary system, and typically grows from multiple foci. UC is most common in the bladder, and upper urinary tract UC (UTUC) is rare. We describe a male who initially presented at a local hospital in 2015 at the age of 70 years with a complaint of painless hematuria. The doctors diagnosed UTUC of the right renal pelvis. After radical nephroureterectomy and bladder cuff excision, the doctors recommended intravesical chemotherapy and regular follow-up, but he rejected this advice. He presented at our hospital again with dysuria in 2016. We identified UC in the residual bladder and performed radical cystectomy and left cutaneous ureterostomy. Unfortunately, he presented again with urethral orifice bleeding in 2021, and we identified urethral UC as the cause. We thus administered radical urethrectomy. Since this last surgery, he has received regular 6-mo follow-ups and has remained in a stable condition. Treatment for upper UTUC should include adjuvant instillation as immunotherapy and intense surveillance.
