RESUMO
INTRODUCTION: The importance of upper tract cytology for evaluating tumors is unclear. We correlated upper tract cytology with histologic findings in patients who underwent nephroureterectomy for upper tract urothelial carcinoma (UTUC) at a single tertiary care referral center. MATERIALS AND METHODS: 137 patients underwent nephroureterectomy between 2004 and 2012. 18 patients were excluded (benign tumors, atrophic kidneys with the remaining 119 patients serving as our study population). Upper tract cytology from the renal pelvis and/or ureter were retrospectively reviewed and analyzed with final pathology data in the remaining patients with UTUC. RESULTS: 57% (68/119) had preoperative upper tract cytology collected. 73% (50/68) patients had abnormal cytology (positive, suspicious) with a sensitivity of 74% (which increased to 90% if atypical included), specificity of 50% and a positive predictive value of 98%. High grade tumors were more common than expected (77% high grade vs. 20% low grade). Abnormal cytology did not predict T stage or tumor grade. Interestingly, positive upper tract cytology was found in all of the UTUC CIS specimen. CONCLUSIONS: Upper tract cytology has been utilized to support the diagnosis of upper tract urothelial carcinoma. Our data demonstrates that abnormal cytology correlates well with the presence of disease but does not predict staging or grading in these respective patients.

One hundred and twenty-one transrectal ultrasound examinations of the prostate were performed between August and October of 1987. Indications included screening in 41 patients, evaluation of bladder outlet obstruction in 63 patients, evaluation of palpable nodules in 6 patients, and evaluation after transurethral resection of the prostate in 11 patients. A total of five patients were discovered to have prostate cancer after biopsy of a hypoechoic lesion in a normal feeling prostate by digital rectal examination. One patient was from the screening group, two patients with bladder outlet obstruction and two patients from the postransurethral resection group. All six patients with palpable nodules were diagnosed as having a cancer: Stage B2 on the rectal examination and two of the six patients were upstaged to Stage C by ultrasound criteria. In our hands transrectal ultrasound of the prostate is a valuable adjunct in the urological armamentarium with clear application in the diagnosis and staging of prostate cancer.

Ninety-one children that were subjected to transabdominal radical nephrectomy are reviewed. The patients' ages ranged from 20 days to 10 years. Forty cases had a right side tumor and 44 a left side tumor; bilateral tumor incidence was 7.70% (7 cases). The tumor weight incidence was 75% for greater than or equal to 500 g and 37.5% for greater than or equal to 1,000 g. Incidence of local extension of the disease was 21.98%. Intraoperative complications were 12 ruptures of the kidney capsule, 1 laceration of the cecum, 1 opening of the pleura, 1 section of the superior mesenteric artery, and 1 section of the right common iliac artery. The mortality rate in unilateral surgery, because of intraoperative massive hemorrhage, was 3/83 (3.61%). One patient with bilateral tumor died because of acute renal insufficiency and sepsis. One patient with caval thrombus which extended up to the right atrium died because of intraoperative massive pulmonary embolism.

Twenty-nine patients with squamous cell carcinoma of the penis underwent bilateral ilioinguinal groin dissection 6 weeks after removal of the primary penile lesion. Eighty percent of the patients were alive and without evidence of disease at 5 years when the dissected lymph nodes were negative. When positive nodes were found, 62.5% of the patients were alive and without evidence of disease at 5 years: two of these patients had one iliac deep node positive each. The mortality rate at 5 years because of progression of disease was 6.6% when the dissected lymph nodes were negative, as compared to 37.5% when the dissected lymph nodes were positive.

Between 1952 and 1976 192 consecutive cases of penile epidermoid carcinoma were seen at the Instituto Nacional de Enfermedades Neoplascias of Lima, Peru. The mean age when the disease developed was 60.5 years, with a peak incidence between 60 and 64 years (32 patients). No correlation was observed between extensive lesions of the shaft of the penis to high pathological staging. Clinical examination of the inguino-crural nodes is not a good criterion for staging. We wait six weeks after eradication of primary lesion before lymphadenectomy. No correlation exists between grade and pathological stage. When no lymph node was positive, the overall survival rate over five years was 90.69%; when lymph nodes were metastasized there was an overall survival rate over five years of only 9.39 percent. The coefficient of cancer versus noncancer cause of death was 1.25 for pathological stage I, 3.09 for pathological stage II, 4.83 for pathological stage III, and 10.000 for pathological stage IV. Our patients did have advanced disease, as 57.14% of deaths occurred at two years and 25.21% more at five years.
