This study compared the infection rates, degree of encrustation, symptoms, and complications in patients regarding the duration of urethral catheterisation (three weeks, six weeks, and eight weeks).
A cross-sectional study with stratified simple random sampling.
Urology Unit, Korle Bu Teaching Hospital.
One hundred and thirty-seven male patients with long-term urinary catheters.
Participants were grouped into 3 weeks, 6 weeks, and 8 weeks duration of catheter replacements.
Symptoms due to the urinary catheters, urinalysis, urine and catheter tip cultures, sensitivity, and catheter encrustations were assessed.
Eighty-six patients had a primary diagnosis of benign prostatic hyperplasia (BPH), 35 had urethral strictures,13 had prostate cancer, two had BPH and urethral strictures, and one participant had bladder cancer. There was no difference in the symptoms the participants in the different groups experienced due to the urinary catheters (p > 0.05). The frequency of occurrence of complications (pyuria, p = 0.784; blocked catheter, p=0.097; urethral bleeding, p=0.148; epididymo-orchitis, p=0.769 and bladder spasms, p=1.000) showed no differences in the three groups. There was no statistical difference in the urinalysis for the three groups (p>0.05) and the degree of encrustations (3 weeks: 0.03 ± 0.06, 6 weeks: 0.11±0.27 and eight weeks: 0.12 ±0.27) with p=0.065.
In this study, the duration of urinary catheterisation using silicone Foley's catheters did not influence the complication and symptom rates; hence silicon catheters can be placed in situ for up to 8 weeks before replacement instead of the traditional three-weekly change.

本研究比较了不同导尿管留置时间（3 周、6 周和 8 周）患者的感染率、结石程度、症状和并发症。
分层简单随机抽样的横断面研究。
科勒布教学医院泌尿科。
137 名长期留置导尿管的男性患者。
参与者被分为 3 周、6 周和 8 周的导管更换组。
评估导管相关症状、尿液分析、尿液和导管尖端培养、药敏试验和导管结石。
86 例患者的主要诊断为良性前列腺增生症（BPH），35 例为尿道狭窄，13 例为前列腺癌，2 例为 BPH 和尿道狭窄，1 例为膀胱癌。不同组患者因导尿管引起的症状无差异（p＞0.05）。并发症发生率（脓尿，p=0.784；导管堵塞，p=0.097；尿道出血，p=0.148；附睾炎-睾丸炎，p=0.769 和膀胱痉挛，p=1.000）在三组之间无差异。三组的尿液分析（p＞0.05）和结石程度（3 周：0.03±0.06，6 周：0.11±0.27 和 8 周：0.12±0.27）无统计学差异（p=0.065）。
在本研究中，使用硅胶 Foley 导尿管留置导尿的时间并不影响并发症和症状发生率；因此，硅尿管可以在原位放置长达 8 周，而不是传统的 3 周更换。
