The effectiveness of a short perioperative course with pivampicillin/pivmecillinam in transurethral prostatic resection: clinical results.

In a randomized control study comprising 261 patients undergoing transurethral prostatic resection (TUR), the effect of a short perioperative course with the oral combination of pivampicillin/pivmecillinam (PAPM) was analysed in 129 patients. The study was divided in 2 parts: the first 60 patients received 450 mg and the following 69 patients, 900 mg every 12 h until removal of catheter but not longer than for 1 week. 132 controls received parenterally 1 g of cefotaxime (CFT) daily throughout the study. During the first part of the study the frequency of bacteriuria in the PAPM group was 43% preoperatively and 30% 10 days postoperatively, during the second part 47% and 12%, respectively (p less than 0.025). In the CFT group the frequency of bacteriuria was reduced from 52% preoperatively to 28% postoperatively. The prophylactic effect (i.e. the protection against acquired bacteriuria) was 96% and 92% in the PAPM and the CFT groups, respectively. Preoperative bacteriuria was eliminated in 40% of the patients during first part and 69% during second part in the PAPM group, while corresponding figures were 48% and 46% in the cefotaxime group. There were 2 cases of septicemia and 5 of upper urinary tract infections throughout the study evenly distributed between the two groups. Oral pivampicillin/pivmecillinam 900 mg every 12 h was found to be a good alternative for perioperative antibiotic prophylaxis at TUR.

The effectiveness of a short perioperative course with pivampicillin/pivmecillinam in transurethral prostatic resection: bacteriological results.

We analysed the bacteriological findings in 261 patients undergoing transurethral prostatic resection (TUR) and receiving either an oral course of pivampicillin/pivmecillinam (PAPM) or parenteral cefotaxime (CFT) in a randomized clinical trial. 123/261 patients had bacteriuria before TUR; 80% of the bacteria were gram-negative strains and 20% gram-positive. 88% of the strains were sensitive to PAPM and 93% to CFT but only 58% to ampicillin. The sensitivity of recurring bacteria was not influenced by the short course of PAPM or CFT. The faecal flora was influenced by the treatment with PAPM in terms of growth of Pseudomonas aeruginosa and fungi in some patients, but no resistant strains of Enterobacteriaceae were observed. The peak serum concentrations of ampicillin and mecillinam were obtained 2 hours after intake of the drug and were 4.5 micrograms/ml and 1.7 micrograms/ml respectively. The prostate tissue concentration of ampicillin and mecillinam (AM) was low.

Impact of short perioperative courses of cefotaxime on aerobic bacterial flora in patients undergoing transurethral prostatic resection.

The influence of short-term prophylactic courses of cefotaxime on the microbial environment was studied. The distribution of bacterial species and their antibiotic resistance was recorded in isolates collected over a six-year period, during which time cefotaxime was used for perioperative prophylaxis in patients undergoing transurethral prostatic resection. In three consecutive studies covering the six-year observation period, the species distribution and antibiotic resistance patterns remained essentially unchanged for both cefotaxime and ampicillin. Examination of the faecal coliform flora in 23 patients given cefotaxime revealed no marked qualitative or quantitative change in the flora. It is concluded that short-term prophylactic courses of cefotaxime do not promote the emergence of resistance in the aerobic bacterial flora.

Long-term follow-up after transurethral prostatic resection with or without a short peri-operative antibiotic course.

This study was undertaken to analyse the results in 192 patients who 3 to 4 years earlier had undergone transurethral resection (TUR) in a controlled clinical trial on the value of a short peri-operative course of antibiotics. The survival rate was comparable in both groups. Most deaths were due to cardiovascular disease and/or cancer of the prostate and the gastrointestinal tract. Infectious events predominated in the control group and more antibiotics were prescribed for these patients during follow-up than for the patients in the peri-operative antibiotic group. Bacteriuria was found in 24% of patients, evenly distributed between the groups. Eighty-three per cent were satisfied with the results of prostatectomy but 38% complained of symptoms from the lower urinary tract. The maximum urinary flow rate was not influenced by the presence of bacteriuria and/or symptoms. There was no difference between the groups regarding mortality or morbidity except for the frequency of post-operative urethral stricture formation, which was significantly higher in the controls. It was concluded that prospective long-term follow-up is indicated to assess the effect of short peri-operative antibiotic courses.

Species distribution and antibiotic sensitivity of bacteria isolated pre- and postoperatively from patients undergoing transurethral prostatic resection.

The identity and antibiotic sensitivity of the isolated bacteria from 179 patients undergoing transurethral resection of the prostate were analysed. The patients were randomized into a group receiving a short course of cefotaxime in conjunction with the operation and a control group given no antibiotics. Preoperatively 70 patients had bacteriuria (greater than or equal to 10(7) CFU/l) with a predominance of Gram-negative bacteria (57 isolates, mainly Escherichia coli, Enterobacter, Klebsiella ssp, Proteus ssp), although Gram-positive species (24 isolates, mainly enterococci and Staphylococcus epidermidis) were also frequently encountered. Preoperatively isolated pathogens were evenly distributed in both groups and the sensitivity pattern was comparable. In the cefotaxime group postoperative recurrence of the preoperatively identified bacteria occurred in a lower frequency (11/43) than persistence in the control group (24/38). Only Gram-negative pathogens were isolated from patients with postoperative septicemia and upper urinary tract infections indicating that it is most important to direct prophylaxis against Gram-negative bacteria. A high degree of sensitivity against cefotaxime, gentamicin, trimethoprim, co-trimazine and a combination of ampicillin and mecillinam was recorded among both pre- and postoperatively isolated bacteria.

A short antibiotic course given in conjunction with and after catheter removal consecutive to transurethral prostatic resection.

In a prospective randomized study of 96 patients, the effect of a short antibiotic course given after transurethral prostatic resection was analysed. Cefotaxime (1 g. i.m. every 12 hours to a total of 3 g) was given to 47 patients with the first doses when the postoperative catheter was removed while 49 were assigned to a control group without antibiotic. The frequency of bacteriuria was 48% preoperatively in the cefotaxime group and 33% six weeks postoperatively. In the control group the corresponding figures were 63% and 50% (p greater than 0.1). There were two cases of septicemia in each group immediately post-operatively whereas upper urinary tract infection developed in five patients in the control group and one patient in the cefotaxime group (p greater than 0.1). The total number of infectious and non-infectious complications was significantly greater in the control group (22) compared to the cefotaxime group (12) (p less than 0.05). The patients receiving the antibiotic remained a shorter time in hospital as compared to the controls. Bacteriological analysis showed a good in vitro effect of cefotaxime on isolated bacteria.

The effect of a short antibiotic course in transurethral prostatic resection.

In a prospective randomized study of 192 patients, the effect of a short course of cefotaxime in connection with transurethral prostatic resection was analyzed. The antibiotic was given to 98 patients, while 94 were assigned to a control group without antibiotic. The frequency of bacteriuria in the cefotaxime group was 43% preoperatively and 18% six weeks postoperatively. In the control group the corresponding figures were 40 and 42% (p less than 0.01). Complicated postoperative infection did not occur in the cefotaxime group, but in the control group there was one case of septicemia and seven patients had upper urinary tract infections (p less than 0.01). In the cefotaxime group, patients with preoperatively negative urine culture were prevented from acquiring bacteriuria, and 67% of preoperatively present infections were eliminated at six weeks after the operation, as compared with 30% in the control group. There were essentially no side effects of cefotaxime. Renal function was not influenced by the combination of cefotaxime and furosemide.
