Clinical Case of Urothelial Carcinoma with Implantation Metastasis

Urothelial cancer ranks 4th in the prevalence of malignant tumors after prostate cancer (or mammary glands), lung and colorectal cancer. Urothelial cancer of the upper urinary tract is quite rare and accounts for 5–10% of all cases of urothelial cancer. The leading clinical symptom of cancer of the renal pelvis and ureter is hematuria. Metastasis of tumors of the upper urinary tract is observed quite often. Metastasis of the tumor can be carried out lymphogenically into the para-aortic and parailiac lymph nodes, hematogenous to the liver, lungs, and bones. In addition, urothelial cancer often spreads through the urinary tract mucosa, mainly in the caudal direction. Currently, multidetector computer urography is considered the gold standard for examining the upper urinary tract, taking the place of excretory urography. This study should be performed under optimal conditions, especially with the inclusion of the excretory phase. It is necessary to perform scanning in a spiral mode (with a step of 1 millimeter) before and after the contrast medium. Clinical case of a patient with urethral carcinoma with implantation metastases in the ureter and in the bladder is presented.
