UPPER URINARY TRACT TUMOR IN A YOUNG PATIENT: A CASE REPORT

Medicine

Tumors of the upper urinary tract (UUT) are growths that develop in the upper urinary system, including the calyces, renal pelvis, and ureter. Although rare, these tumors are not uncommon, and they are most often of urothelial origin. The average age at diagnosis in Europe is approximately 73 years. Hematuria is the primary indicative symptom, and the diagnostic process involves morphological examinations such as ultrasound and computed tomography, endoscopic procedures like cystoscopy and ureteroscopy, and biological investigations such as urinary cytology. Total nephro-ureterectomy with excision of the bladder cuff remains the reference oncologic intervention. Despite recent technical advances in the treatment of this condition, conservative treatment, whether endoscopic or surgical, is not routine. We present the case of a 36-year-old patient, a smoker for 10 years at a rate of 10 packs per year. Clinically, he presented with hematuria and left lumbar pain evolving for 3 months. Computed tomography (CT) confirmed the presence of a budding tumor in the left pyelocalyceal cavities. The patient underwent a left nephro-ureterectomy with excision of the bladder cuff, and histological examination revealed an infiltrating urothelial carcinoma involving the chorion.
