Investigation of re-catheterizationin patients with benign prostatic hyperplasia and acute urinary retention after failure of routine indwelling catheterization / 中国实用护理杂志

ABSTRACT

Objective:To investigate the safety and efficacy of two methods for urethral catheterization in patients with benign prostatic hyperplasia and acute urinary retention after failure of routine indwelling catheterization.Methods:This was a randomized controlled study. From January 2020 to December 2021, 80 patients with benign prostatic hyperplasia complicated with acute urinary retention who failed of catheterization by conventional methods in the Department of Urology, Beijing Aerospace General Hospital were divided into observation group and control groupaccording to the random number table method, with 40 patients in each group. The observation group used a 12 Fr silicone Foley catheter, which was folded 2 cm in front of the catheter. The control group used a 16 Fr silicone curved Coudé catheter. The success rate of catheterization, catheterization time, incidence of gross hematuria after catheterization, and Visual Analog Scale (VAS) were compared between the two groups.Results:The success rate of catheterization in the observation group was 82.5% (33/40), which was significantly higher than 62.5% (25/40) in the control group, and the difference was statistically significant ( χ2 = 4.01, P<0.05). There was no significant difference in the incidence of gross hematuria, the time of catheterization from urethra into bladder and VAS between the two groups (all P>0.05). Conclusions:Technique for manipulating a 12 Fr catheter before insertion into urethral meatus in a difficult catheterization has high success rate and not significantly increases the side effects in patients with benign prostatic hyperplasia with acute urinary retention after failure of routine indwelling catheterization.
