Cystic renal masses • A renal mass that is not clearly a simple cyst by strict ultrasound criteria should be evaluated further with computed tomography (CT). • A dedicated (thin-slice) renal CT scan remains the single most important radiographic test for delineating the nature of a renal mass.

Clinical Presentation • Because of the sequestered location of the kidney within the retroperitoneum, many renal masses remain asymptomatic and nonpalpable until they are advanced. • With the more pervasive use of noninvasive imaging for the evaluation of a variety of nonspecific symptom complexes, more than 50% of RCCs are now detected incidentally.

Urothelial Cancer: Bladder Endoscopic surgery, BCG instillation Radical surgery
Detection of Urothelial Carcinoma • Gross, painless hematuria is the primary symptom in 85% of patients with a newly diagnosed bladder tumor, and microscopic hematuria occurs in virtually all patients. • The hematuria is usually intermittent; therefore any episode of gross hematuria should be evaluated even if subsequent urinalysis is negative. • Fifty percent of patients with gross hematuria will have a demonstrable cause, 20% will have a urologic malignancy, and 12% will have a bladder tumor.
A full hematuria evaluation • Cystoscopy • Urine cytology • Upper-tract imaging (primarily a CT scan of the abdomen and pelvis) • PSA blood test

Testis Cancer: Germ Cell Tumor
Initial presentation • Painless testicular mass • A firm intratesticular mass should be considered cancer until proven otherwise and should be evaluated further with scrotal ultrasonography. • Prior studies show that up to one third of testicular tumors are initially misdiagnosed as epididymitis or hydrocele.
Diagnosis • In men presenting with a testicular mass, hydrocele, or unexplained scrotal symptoms or signs, scrotal ultrasonography should be considered an extension of the physical examination because it is widely available, inexpensive, and noninvasive. • Testicular cancer is one of the few malignancies associated with accurate serum tumor markers (LDH, AFP, and h. CG), a finding that is essential in its diagnosis, prognosis, treatment, and monitoring. • Serum tumor marker levels should be obtained at diagnosis, after orchiectomy, to monitor for response to chemotherapy, and to monitor for relapse in patients on surveillance and after completion of therapy.
