Effect of transurethral indwelling catheter on serum prostate-specific antigen level in benign prostatic hyperplasia

Patients with Elevated Serum PSA and Indwelling Catheter after Acute Urinary Retention: Prospective Study of 63 Patients with 7-Year Follow-Up

“…It must be emphasized that one of these cases fulfilled the criteria of clinical insignificant cancer [18,19]. This low detection rate could be supported by the results of Batislam et al [1]. We want to emphasize that a mean 12.677 Ϯ 1.42 biopsies per patient were done in our study.…”

“…Elevated PSA levels in patients with AUR are well recognized and thought to be a consequence of prostate tissue ischemia and infarction [8,9]. The presence of an indwelling catheter after AUR can result in maintained elevation of PSA levels [1]. In our study we included only patients with spontaneous AUR.…”

“…Some studies found a statistically significant relationship between indwelling urethral catheter and elevated serum PSA values [1]. Alternatively, other investigators have found that indwelling urethral catheter does not cause any clinically or statistically significant change in PSA levels, and elevated PSA levels mandate prompt evaluation to exclude prostate cancer [2].…”

Renal donors with prostate cancer, no longer a reason to decline

“…A study has shown marked elevation of PSA rates following catheterisation for acute urinary retention, making it harder to interpret PSA levels in terms of prostate cancer. 19,20 Digital rectal examination The sensitivity and specificity of digital rectal examination is also variable but increases with prostate tumour size, making it a useful screening tool for larger tumours. 21 An autopsy series has shown that the metastases risk increasing with clinical stage.…”

PSA levels in men with spinal cord injury and under intermittent catheterization

“…PSA is an organ (prostate)‐specific marker, and its level can be increased in various situations such as following urologic manipulations. The relationship between indwelling urethral catheter in patients with acute urinary retention (AUR) and elevated serum PSA values has been already described 1–3. Batislam et al1 compared 45 patients using indwelling catheter with 45 noncatheterized patients submitted to prostatectomy for benign disease and found a direct relationship between indwelling urethral catheter and elevated serum PSA value.…”
