A nation-wide study was performed to estimate the incidence of bladder, kidney, renal pelvis and ureter, prostate, testicular and other genitourinary cancer among Koreans in Korea using medical records of the inpatients of the beneficiaries of the Korea Medical Insurance Corporation (KMIC) from Jan. 1, 1989 to Dec. 31, 1989. The crude incidence rate of bladder cancer (ICD-9 188) is estimated to be 4.43 and 0.98 per 100,000 in males and females, respectively. Around 1,093 new cases of bladder cancer (895 male and 198 female) are estimated to occur in a year. The adjusted rate for the world population is 7.76 in males and 1.19 in females which is similar to that of Japanese in Osaka and Chinese in Shanghai, but lower than in American whites and blacks. The crude incidence of kidney, renal pelvis and ureteral cancer (ICD-9 189) is estimated to be 1.61 and 0.87 in males and females, respectively. Around 507 new cases of kidney, renal pelvis and ureteral cancer (332 male and 175 female) are estimated to occur in a year. The adjusted rate for the world population is 2.69 in males and 1.04 in females. In the prostate (ICD-9 185), the crude incidence rate of cancer is estimated to be 1.36. Around 274 new cases of prostate cancer are occurring in a year. The adjusted rate for the world population is 2.98 which is similar to the Chinese rate. The incidence of genitourinary cancer continuously increases with age.

This study was performed to assess the changes occurring in the field of urology with developments in outpatient surgery during a 5 year period. Using ICD-9-CM code, data for all urology procedures performed in the main operating rooms, day surgery and laser centre operating rooms of a large, general hospital were collected for the years 1987-92. A substitution index (SI) was determined as the ratio of the number of outpatients to the total number of procedures and expressed as a percentage. Changes in the SI reflects the degree to which emphasis has shifted from conventional inpatient to outpatient surgery. It was found that 26% of urology procedures were being performed as outpatients in 1987, and this increased to 42% by 1992. When broken down according to organ, the greatest increase in SI from 1987 to 1992 was for the kidney (57%) and the least, the penis (2%), with ureter, urethra, testes and scrotum all revealing intermediate, but significant, increases (27, 28 and 24% respectively). This paper thus demonstrates that, as in other fields, urology has experienced a marked increase in outpatient surgery. With developments in surgical and anaesthetic techniques, financial pressures, changing physician and patient attitudes and technological advances, further increases in urology outpatient care can be expected.

Survival of adult patients with cancer of the kidney, renal pelvis, ureter and urethra (ICD-9 189) was analysed using data from the EUROCARE II study, a collaborative project of 45 population-based cancer registries in 17 European countries. For the period 1985-1989, more than 24000 patients were included and 5-year relative survival was 48%. Large variations were observed between countries with 5-year relative survival ranging from 57% in France, 53% in Italy and 51% in Spain to 35% in Denmark, 33% in Poland and 30% in Estonia. A number of registries also provided information on previous years and survival was seen to improve with time from 44% in 1978-1980 to 50% in 1987-1989. Age was an important determinant of survival with 5 year survival rates decreasing from 63% in patients aged 15-44 years to 36% in patients aged 75 years and older. Variation in survival rates by country or time is probably related to differences in the distribution of tumour stage at diagnosis. Evidence to confirm this theory is, however, lacking.

In the United States, approximately 4 million people per year are infected with Ascaris lumbricoides. We reviewed the common presentations of complications of Ascariasis infection in the Emergency Department (ED) and the diagnostic tools and treatment available. This was a retrospective case review conducted on all patients diagnosed with Ascariasis (using ICD-9 codes) over a 6-year period at Los Angeles County and University of Southern California Medical Center. Three patients with distinct complications secondary to Ascariasis were chosen, and all ED and inpatient records were reviewed. The patient's age, sex, race, presenting symptoms, data, outcome, and ED course and diagnosis were recorded. The three cases included a periappendiceal abscess, Loeffler's syndrome, and biliary colic/choledocholithiasis. The first patient underwent a computed tomography-guided drainage of the abscess. The second patient received supportive care and antibiotic therapy secondary to a superimposed bacterial pneumonia. The third patient underwent endoscopic retrograde cholangiopancreatography with sphincterotomy. All three patients had a stool ova and parasites positive for A. lumbricoides, and all received a 3-day course of mebendazole. Symptomatic cases of Ascariasis may present to EDs in the United States. Important diagnostic tools for the ED include chest X-ray, X-ray of the kidney-ureter-bladder and ultrasonography. Single-dose medications given in the ED are very effective in eradicating A. lumbricoides infection, thus avoiding hospitalization.

In Europe, renal cancer (that is neoplasia of the kidney, renal pelvis or ureter (ICD-9 189 and ICD-10 C64-C66)) ranks as the seventh most common malignancy in men amongst whom there are 29,600 new cases each year (3.5% of all cancers). Tobacco, obesity and a diet poor in vegetables are all acknowledged risk factors, along with specific occupational and environmental factors. A familial history of renal carcinoma is also likely to increase the risk. Renal carcinoma may remain clinically occult for most of its course. The classic presentation of pain, haematuria, and flank mass occurs in only 9% of patients and is often indicative of advanced disease. Approximately 30% of patients with renal carcinoma present with metastatic disease, 25% with locally advanced renal carcinoma and 45% with localized disease. Metastases are typically found in the lung, soft tissue, bone, liver, cutaneous sites, and central nervous system. The most important staging technique is a computed tomography (CT) scan of the whole abdomen. Survival rates are more favourable for patients with tumours confined to the kidney. Five-year survival for patients with metastatic renal carcinoma is comprised between 0 and 20%. Radical nephrectomy is the standard intervention for renal cancer. Intrinsic resistance to chemotherapy has long been a hallmark of renal carcinoma. Limited options are available for the systemic therapy, and no chemotherapeutic regimen is accepted as a standard of care. Biologic agents represent the major effective therapies for widespread metastatic renal cancer. An antiangiogenic strategy, the neutralization of VEGF, can slow the growth rate of advanced cancer.
