Risk Factors for Early Urethral Stricture After Mono-Polar Transurethral Prostate Resection: A Single-Center Experience

Aim This study aimed to investigate the incidence of urethral stricture during the early period after transurethral resection of the prostate (TURP) and the risk factors affecting the development of urethral stricture in patients treated in our clinic. Material and methods This retrospective study included patients who underwent TURP due to benign prostate hyperplasia (BPH) and had complete postoperative follow-up data of at least 12 months. Univariate and multivariate logistic regression analyses were performed to evaluate the relationship between urethral stricture and eight parameters (age, body mass index [BMI], prostate volume, number of comorbidities, amount of tissue removed, operative time, perioperative blood loss, and catheterization duration). Results Of the 3069 patients who underwent TURP in our clinic during the study period, 1740 patients with complete clinical data were included in the study. Mean age was 67.83 ± 5.80 years and mean body mass index (BMI) was 27.63 ± 4.31 kg/m(2). Median preoperative prostate volume was 50.0 (range, 41.0-62.0) mm(3) and the average amount of tissue removed during surgery was 20.0 (range, 12.0-30.0) g. Urethral stricture was detected in 3.9% (67/1740) of the patients during a minimum of 12 months of follow-up period after TURP. In multivariate analysis, prolonged operative time and high comorbidity burden were found to be risk factors for urethral stricture (p<0.001 for both). Conclusion Early urethral stricture remains an important complication of TURP. Our results show that prolonged operative time and high comorbidity burden are factors that increase the risk of urethral stricture.
