To evaluate the safety of near infrared fluorescence (NIRF) of intravenously injected indocyanine green (ICG) during open partial nephrectomy, and to demonstrate the feasibility of this technology to identify the renal vasculature and distinguish renal cortical tumors from normal parenchyma. Patients undergoing open partial nephrectomy provided written informed consent for inclusion in this institutional...
To assess the validity of the American Urological Association guidelines, we investigated 14-year outcomes of men aged ≥50 years who had hematuria detected in a bladder cancer (BC) screening trial, were thoroughly evaluated, and were not found to have urological cancers. The American Urological Association guidelines for follow-up of adults with asymptomatic microhematuria (MH) who have negative evaluations...
Secondary polycythemia is a condition that causes an increase in red blood cell count either because of the physiologic response to stress or inappropriate secretion of erythropoietin. We report a case of a secondary polycythemia caused by ureteropelvic junction obstruction that was successfully treated by laparoscopic nephrectomy.
The incidence of tuberculosis (TB) is increasing worldwide, with more than 20% of cases exhibiting extrapulmonary manifestations. The genitourinary tract is the most common site of extrapulmonary TB. Epididymal TB, although rare, may be the initial location of infection and may cause infertility. The diagnosis depends on culture of the organism but has been facilitated by the development of urine...
Bladder cancer is the fourth most commonly diagnosed cancer in men and the eighth most common in women in the United States. While clinicians who diagnose and treat the disease recognize that bladder cancer has a unique demographic profile, the influence of such factors as age, gender and race on incidence, prognosis, and survival of patients is poorly understood, and has not been the subject of intense...
Nineteen cases of breast cancer metastatic to the bladder and diagnosed in living patients have been identified in the English literature. Most patients were symptomatic with evidence of disseminated disease at the time of diagnosis. Metastasis usually occurred many years after diagnosis, and the prognosis was poor. The definitive modality for diagnosis in all cases was cystoscopy, which demonstrated...
We report a case of a complete posterior urethral injury secondary to a penetrating gluteal injury. Posterior urethral injury usually occurs in male patients with pelvic trauma. The reported incidence of urethral injury with pelvic fracture ranges from 1.6% to 25% (mean 10%), with 66% of them being complete posterior urethral ruptures. Causes of posterior urethral disruptions include blunt trauma,...
We report a case of the numb chin syndrome as the presenting symptom in a patient with metastatic prostate carcinoma. The numb chin syndrome is characterized by facial numbness along the distribution of the mental branch of the trigeminal nerve. Most cases of this syndrome that are not dental in origin have been associated with diffuse metastatic disease, particularly with underlying lymphoproliferative...
