摘要

目的:评估术后感染并发症患者经尿道前列腺切除术(TURP)前后尿液的微生物谱:在 2016 年至 2023 年期间开展了一项单中心回顾性观察研究。研究纳入了住院期间接受单极或双极前列腺电切术(TURP)后出现尿路感染(UTI)的患者。根据《指南》对术前和术后尿液进行细菌学检查。如果存在耻骨上导尿管或尿道导尿管,则在进行进一步微生物学检查之前更换引流管。明显的细菌尿水平大于或等于 103 CFU/ml,明显的白细胞尿水平大于或等于 10 个/视野。统计分析采用 IBM SPSS Statistics 23.0:77.9%的 TURP 术后 UTI 病例未检测到细菌尿。同时,根据术前检查,其中 76.2% 的患者没有发现大于或等于 103 CFU/ml 的细菌尿。122 名男性患者中有 17 人(13.9%)在基线时没有细菌尿,但在发生 UTI 后分离出了微生物。29 名患者中只有 19 名(65.5%)在 TURP 术前尿液培养呈阳性,他们的菌尿水平有所下降。在 10 个持续菌尿的病例中,只有 4 个病例分离出了相同的微生物,而在其余 6 个病例中,最初的菌谱被另一种细菌取代:我们的数据表明,采用标准细菌学研究方法,TURP 术后 UTI 患者尿液中微生物的检出率较低。数据表明,标准的抗生素预防方案和持续的抗感染措施部分有效地减少了术前使用标准培养基检测到的范围较窄的需氧微生物,但这并不排除感染过程的发展。

[Microbial spectrum of urine before and after transurethral procedures on the prostate in patients with postoperative urinary tract infections].

Aim: To evaluate the microbial spectrum of urine before and after transurethral resection of prostate (TURP) in patients with postoperative infectious complications.

Materials and methods: A single-center retrospective observational study between 2016 and 2023 was carried out. Patients who developed urinary tract infections (UTIs) after mono- or bipolar TURP during the hospitalization were included. Bacteriological examination of urine obtained before procedure and after the manifestation of UTI was done in accordance with the Guidelines. In the presence of suprapubic or urethral catheter, the drainage was previously replaced with further microbiological study. The level of significant bacteriuria was more or equal 103 CFU/ml, with a level of significant leukocyturia more or equal 10 per field of view. Statistical analysis was carried out using IBM SPSS Statistics 23.0.

Results: Bacteriuria was not detected in 77.9% of cases of UTIs after TURP. At the same time, according to the preoperative examination in 76.2% of these patients, there was no bacteriuria more or equal 103 CFU/ml. In 17 of 122 men (13.9%) without bacteriuria at baseline, microorganisms were isolated after the development of UTIs. A decrease in bacteriuria level was noted in only 19 of 29 patients (65.5%) who had a positive urine culture before TURP. Only in 4 out of 10 cases of persistent bacteriuria the same microorganism was isolated, while in the remaining 6 cases the initial spectrum was replaced by another bacteria.

Conclusion: Our data indicate a low detection rate of microorganisms in urine of patients with UTIs after TURP using a standard bacteriological study. The data indicate that the standard antibiotic prophylaxis regimen and ongoing anti-infective measures are partly effective in reducing a narrow range of aerobic microorganisms detected preoperatively using standard media, which, however, does not exclude the development of an infectious process.
