Impact of Escherichia coli on Urine Citrate and Urease-Induced Crystallization
Escherichia coli (E. coli) is usually not a urease producer. It is, however, often cultured in urinary phosphate containing calculi including ammonium magnesium phosphate stones. This suggests the possibility that E. coli might be involved in stone forming process. The effect of E. coli on urine citrate and urease-induced crystallization in human urine has been studied in vitro. E. coli was found to strongly reduce urine citrate (after 48 hours). In the E. coli inoculated samples, the urease-induced crystallization was increased. There was a strong correlation, r = 0.8, between the citrate decrease and the increase in calcium precipitation. The results indicate that E. coli and the reduced urine citrate influences urease-induced crystallization in vitro

Blunt renal trauma. Analysis of 417 patients
Case records of 417 patients, from a well-defined area, who were hospitalized because of blunt renal trauma during the period 1950-1979 were analyzed. The incidence increased during the final decade, corresponding to a rising incidence of motor traffic accidents and sports injuries. Young patients, between 10 and 29 years of age, were responsible for the increase and half of all patients were in this age group. Associated injuries were frequent. Emergency urography was rare during the earlier part of the investigation period, but the frequency increased strongly thereafter. Treatment was mainly conservative (nonoperative) except in patients with major renal injuries. Nephrectomy was performed in 22 patients. Reconstructive surgery was performed especially in patients with intermediate renal injuries during the final decade. The total mortality was 6.5%. Only 7 patients (1.7%) died from the renal injury. A dramatic reduction in the hospitalization time was noted
