ObjectiveTo investigate the influencing factors for complicating with urethral stricture after transurethral bipolar plasmakinetic prostatectomy (TUPKP) in patients with benign prostatic hyperplasia (BPH). MethodsThe clinical data of 98 BPH patients treated with TUPKP were retrospectively analyzed. The occurrence of urethral stricture 6 months after operation was recorded in all patients, and the baseline data were compared and analyzed between the urethral stricture patients (the stricture group) and non urethral stricture patients (the non-stricture group), including age, diabetes history, preoperative use of antibiotics, operation duration, postoperative urinary tract infection, urinary catheter indwelling time. Multivariate logistic regression was used to analyze the influencing factors for complicating with urethral stricture after TUPKP in patients with BPH. ResultsA total of 7 cases of 98 BPH patients occurred urethral stricture after TUPKP, with the occurrence rate of 7.14%, and other 91 cases (92.86%) did not occurred stricture. Compared to the non-stricture group, the stricture group yielded longer time of operation and urinary catheter indwelling, and higher incidence of postoperative urinary tract infection (all P＜0.05). The analysis of multivariate logistic regression revealed that long operation duration, the presence of postoperative urinary tract infection, long urinary catheter indwelling time were the influencing factors for complicating with urethral stricture after TUPKP in BPH patients (all P＜0.05). ConclusionBPH patients have a certain incidence of urethral stricture after TUPKP, while long operation duration, the presence of postoperative urinary tract infection and long indwelling time of urinary catheter are the influencing factors for complicating with urethral stricture in BPH patients after TUPKP. Clinical intervention measures can be given accordingly, so as to reduce the occurrence of urethral stricture.
