ABSTRACT
OBJECTIVES: To determine whether postvoid urine is a risk factor for the development of lower urinary tract infections (UTIs) in nursing home residents. DESIGN: Prospective surveillance with a follow-up period of 1 year. SETTING: Six Norwegian nursing homes. PARTICIPANTS: One hundred fifty nursing home residents. METHODS: Postvoid residual (PVR) urine volumes were measured using a portable ultrasound. UTIs were registered prospectively for 1 year. RESULTS: Ninety-eight residents (65.3%) had a PVR less than 100 mL, and 52 (34.7%) had a PVR of 100 mL or greater. During the follow-up period, 51 residents (34.0%) developed one or more UTIs. The prevalence of UTI in women was higher than in men (40.4% vs 19.6%; P=.02). There was no significant difference in mean PVR between residents who did and did not develop a UTI (79 vs 97 mL, P=.26). PVR of 100 mL or greater was not associated with greater risk of developing a UTI (P=.59). CONCLUSION: High PVR is common in nursing home residents. No association between PVR and UTI was found.

OBJECTIVE: To examine the prognostic significance of performance status, tumour stage, histological subtype, nuclear grade and histological tumour necrosis (HTN) in a population of consecutive patients subjected to radical nephrectomy for renal cell carcinoma (RCC). MATERIAL AND METHODS: The cohort consisted of 110 males and 86 females with a mean age of 66 years (range 39-88 years). The Eastern Cooperative Oncology Group performance status (ECOG PS) was determined in all cases. The tumours were staged according to the 2002 TNM classification of the American Joint Committee on Cancer. Histological subtype was diagnosed using the Heidelberg classification. Nuclear grading was performed by means of Fuhrman's method. The median follow-up period was 65 months (mean 83 months; range 1-232 months). RESULTS: Median overall survival (OS) was 65 months and median cancer-specific survival (CSS) was 171 months. CSS was correlated with TNM classification, with the longest survival occurring for stage I and II tumours, shorter survival for stage III tumours and shortest survival for stage IV tumours (p<0.001). A significant difference in CSS was found between T1N0M0 and T2N0M0 tumours (p<0.01). A 15-year CSS of 100% was revealed in patients with tumours
