Objective: To find the causes of the failure in the first catheter removal (CR) after transurethral resection of the prostate (TURP) and the related risk factors.
Methods: We collected the clinical data on 285 BPH patients treated by TURP from June 2015 to May 2018. We divided the cases into a successful CR (SCR) and a failed CR (FCR) group and investigated the risk factors for the first CR after TURP by multivariate logistic regression analysis.
Results: CR was successfully performed in 246 and failed in 39 of the 285 cases. In the FCR group, post-CR urinary retention occurred in 15 cases immediately after, severe urinary tract irritation in 13, massive gross hematuria in 7 and urinary incontinence in 4 within 1 month. Multivariate logistic regression analysis showed that the independent risk factors for CR failure included IPSS (OR = 5.106, P = 0.013), preoperative urinary tract infection (OR = 3.835, P = 0.041), prostate volume (OR = 4.160, P = 0.011) and catheter compression time (OR = 4.051, P = 0.017).
Conclusions: The common causes of the failure in catheter removal after TURP included early postoperative urinary retention, urinary infection, secondary hematuria and urinary incontinence.
