Urologic surgery was necessitated by complications following radiotherapy for gynecologic cancer in 17 patients. Four had recurrent malignant disease and 13 were without evidence of malignancy. The median interval to onset of the urologic complications was 18 (range 0-144) months. Ileal substitution was performed because of bilateral ureteral obstruction in two cases, and transureteroureterostomy for unilateral obstruction in one case. Vesicovaginal fistula was present in 14 patients, who underwent urinary diversion--cutaneous ureterostomy and ligation of the other ureter (6 cases), cutaneous ureterostomy and transureteroureterostomy (3) and ileal conduit diversion (5). The immediate morbidity and mortality were determined by the patients' general state of health rather than by presence or absence of recurrent malignant disease. The choice of diversion procedure should be guided by the patient's fitness, the status regarding recurrence of malignancy and the distribution of function between the two kidneys.

Primary uterine lymphoma is a rare gynecologic cancer. Usually it involves rather the cervix than the uterine corpus and most of them are B-cell lymphomas. We describe a case of a 43-year old, asymptomatic patient, arrived observed for ureter dilatation due to a pelvic mass diagnosed by urography. The history of the patient, the presurgical clinical and radiological findings did not reveal any sign of uterine lymphoma. These difficulties show that at present it is not possible to make any prevention for this kind of cancer. The diagnosis of lymphoma was done at frozen section during surgery, but the final diagnosis is reached after two weeks. The patient underwent a debulking surgery of the mass, ureter cleaning with introduction of ureteral stent and a node sampling was done. The correct staging and the surgical and/or medical management of this cancer (not yet standardized) are the most important factors to improve the survival of these patients.

Cervical cancer traditionally has been staged clinically. Advances in imaging could improve the staging of cervical cancer by facilitating the detection of lymph node metastases and micrometastases in distant organs. Such progress could lead to improvements in treatment selection and therefore increase overall survival rates. At the Second International Conference on Clinical Cancer (Houston, TX, April 11-14, 2002), a panel composed of gynecologic oncologists, radiation oncologists, and diagnostic radiologists reviewed relevant technologies. Advances in lymphangiography, ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and lymphatic mapping were reviewed, along with the impact of these advances on the diagnosis, treatment, and survival of patients with cervical cancer. Few cancer centers still use lymphangiography, but the sensitivity of this method ranges from 28% to 83%, with specificity ranging from 47% to 100%. The roles of transabdominal and transvaginal ultrasonography in evaluating cervical cancer are expected to expand when new contrast agents increase the sensitivity of these techniques to parametrial invasion and lymph node metastases; meanwhile, ultrasonography's most significant contributions may involve the identification of uterine and cervical leiomyomas and the evaluation of urinary tract obstruction. Advances in CT have made it a rival technique to MRI, but limitations prevent CT from providing definitive information on certain parameters. MRI, which is valuable because of its superior soft tissue contrast resolution, multiplanar capabilities, and cost-effectiveness, is used to determine the size of the cervix and to detect certain types of invasion, characteristics of lymph nodes, and the presence of disease in the ureter, lung, and liver. PET with 2-[fluorine-18]fluoro-2-deoxy-D-glucose has been found to detect abnormal lymph node regions better than CT does but PET can also be used in conjunction with CT to measure tumor dimensions. PET also has become a method for identifying tumors that are unresponsive to chemoradiation. When used together with immunohistochemical and molecular techniques as well as conventional stains, sentinel lymph node mapping, an important development in the surgical management of solid tumors, is expected to improve gynecologic cancer management. Advances in imaging methods and in contrast agents, along with advances in the combined use of the two, are expected to make imaging technologies more valuable in cervical cancer assessment.
