Qualitative determination of urinary human complement factor H-related protein (hcfHrp) in patients with bladder cancer, healthy controls, and patients with benign urologic disease.

OBJECTIVES: To assess the diagnostic quality of human complement factor H-related protein (hcfHrp, BTA STAT(TM)) as a qualitative urinary marker for bladder cancer. METHODS: Urine samples of 354 individuals (76 healthy volunteers, 111 patients with benign urologic disorders, 167 patients with histologically proven bladder cancer) were examined prior to therapy for the presence of hcfHrp. RESULTS: Overall test sensitivity was 62.9%. Sensitivity of low-grade/low-stage tumors was <50% and was thus comparable to published sensitivities of urinary cytology. In high-stage, high-grade tumors sensitivity was 100 and 77.3%, respectively. Superficial tumors with high risk of progression (pT1G3) were detected significantly better (88.9% sensitivity) than low-risk superficial tumors (pTa G1-3/pT1G1-2; 48.2%; p < 0.001). The overall specificity (healthy individuals and patients with benign urologic disease) was 93.0%. CONCLUSION: Since test sensitivity is comparable to urinary cytology and specificity is excellent, hcfHrp should be further evaluated in prospective studies focussing on the follow-up of patients with bladder cancer.

The spectrum of urological disease in patients with spina bifida.

BACKGROUND: [corrected] Urological complications are the major cause of ill health during childhood and adult life of patients with spina bifida but the significance of urinary tract disease on the individual and the healthcare services is underemphasised. AIM: To assess the effects of spina bifida on the individual and the healthcare services. METHODS: A retrospective review was performed to assess the frequency and significance of urological conditions requiring hospital attendance in patients with spina bifida currently attending a specialised multidisciplinary clinic over a period of six months. RESULTS: Urinary sepsis accounted for the majority of admissions (62%), while 38 of 62 patients required 60 surgical procedures. Targeting the primary urological abnormality (the dysfunctional and usually poorly compliant bladder) allows implementation of effective treatments, including regular intermittent bladder catherisation (52%) in order to preserve upper renal tract function. Associated postural abnormalities complicated both conservative and interventional therapies. CONCLUSION: This study highlights the surgical commitment for units caring for patients with spina bifida, the important considerations for the future healthcare services, and the range and severity of urological diseases encountered by these patients.

Efficacy and safety of tamsulosin in the treatment of urological diseases.

The alpha(1)-adrenoceptor antagonist, tamsulosin, is selective for alpha(1A)- and alpha(1D)- over alpha(1B)-adrenoceptors. Both placebo-controlled and comparative studies with other agents have demonstrated tamsulosin to be an effective treatment for patients with lower urinary symptoms suggestive of benign prostatic hyperplasia. Its effectiveness appears to be maintained over many years. Tamsulosin may also effectively reduce lower urinary tract symptoms in other urological diseases. A dose of tamsulosin 0.4 mg/day has a tolerability close to that of placebo and has little, if any, blood pressure lowering effects. Tolerability and lack of blood pressure lowering are maintained even in high-risk patients such as those with cardiovascular comorbidity and/or comedication. Apart from adrenoceptor subtype-selectivity, a smooth pharmacokinetic profile of its modified-release formulation and a selective accumulation in target tissues may contribute to an excellent efficacy:tolerability ratio.

[The prospects for the study of the prevalence of urologic diseases in the RSFSR].

Despite an insignificant (2-3%) percentage in the pattern of total morbidity, renal and urinary diseases affect all age groups and lead to severe complications. They cause temporary disability, invalidity and mortality of a great part of the productive population, significantly damaging the economic status of the country. Therefore, the study of their incidence rate and temporary disability induced by them at the industrial enterprises in certain fields of the RSFSR national economy is of importance as it may reveal the reasons which in turn may be used for the reduction of incidence. This is of great scientific and practical value and enables the concrete measures to be developed for lowering the incidence of urological diseases.

[Studies of enzymuria and proteinuria: Report 1: N-acetyl-beta-glucosaminidase in urological diseases].

N-Acetyl-beta-glucosaminidase (NAG) exists in renal tubules and seminal tract. We measured the NAG level in patients with urinary tract and seminal tract diseases and evaluated its clinical significance. The urinary NAG level was high in renal tubular function disorders such as glomerulonephritis, diabetic nephropathy and hydronephrosis. In these patients, NAG-isoenzyme studies indicated that the A-type isoenzyme decreased while the B-type isoenzyme increased. On the other hand, in the seminal tract disease patients, the urinary NAG level was high in benign prostatic hypertrophy with a catheter indwelling and in prostatitis. Urinary and seminal NAG-isoenzymes were measured in normal subjects. The isoenzyme patterns for urinary NAG and seminal NAG differed. The urinary NAG isoenzymes were measured in acute prostatitis patients, we found that the A-type isoenzyme decreased and the B type increased. In conclusion, when the A/B ratio of the NAG-isoenzyme is close to 24.9/75.0 in the urine, the presence of urological diseases in which seminal plasma could be mixed in, especially prostatic diseases, should be suspected.

Dropout in a longitudinal, cohort study of urologic disease in community men.

BACKGROUND: Reasons for attrition in studies vary, but may be a major concern in long-term studies if those who drop out differ systematically from those who continue to participate. Factors associated with dropout were evaluated in a twelve-year community-based, prospective cohort study of urologic disease in men. METHODS: During 1989-1991, 2,115 randomly selected Caucasian men, ages 40-79 years from Olmsted County, Minnesota were enrolled and followed with questionnaires biennially; 332 men were added in follow-up. A random subset (approximately 25%) received a urologic examination. Baseline characteristics including age, benign prostatic hyperplasia (BPH) symptoms, comorbidities, and socioeconomic factors were compared between subjects who did and did not participate after the twelfth year of follow-up. RESULTS: Of the 2,447 men, 195 died and were excluded; 682 did not participate in 2002. Compared with men in the 40-49 year age group, men > or = 70 years of age at baseline had a greater relative odds of dropout, 2.65 (95% CI: 1.93, 3.63). In age-adjusted analyses, relative to men without stroke, men who had suffered a stroke had a higher odds of dropout, age-adjusted OR 3.07 (95% CI: 1.49, 6.33). Presence of at least one BPH symptom was not associated with dropout, (age-adjusted OR 1.12 (95% CI: 0.93, 1.36)). CONCLUSION: These results provide assurance that dropout was not related to primary study outcomes. However, factors associated with dropout should be taken into account in analyses where they may be potential confounders.

[Urinary excretion of N-acetyl-beta-D-glucosaminidase in patients with urological disease: with special reference to hydronephrosis].

Activity of urinary N-acetyl-beta-D-glucosaminidase (NAG) has been studied in patients with urological diseases. In most patients with benign prostatic hyperplasia, prostate cancer and bladder cancer, activity of urinary NAG was elevated (92.9%), especially in cases of indwelling catheterization or poor visualization of IVU. Urinary NAGs were also elevated for all patients with renal stones, ureter stones, uretero-cutaneous stomy or a single kidney. In hydronephrosis or hydronephrosis with hydroureter patients, urinary NAG level was low pre-operatively, but increased post-operatively. Urinary beta 2-microglobulin (BMG) showed a similar tendency in patients with hydronephrosis or hydronephrosis with hydroureter. Electronmicroscopic observations of the kidney in such patients revealed many primary and secondary lysosomes.
