Purpose
The occurrence of urethral stricture after transurethral resection of the prostate (TURP) is one of the major complications. We retrospectively investigated the effect of routinely urethral dilatation before transurethral resection of the prostate (TURP) for preventing urethral stricture.
Material and methods
From January 2010 to December 2018, a total of 651 patients who underwent TURP for benign prostatic hyperplasia (BPH) was included in this study. We divided into two groups: Group A (295 patients, routinely urethral dilatation before TURP) and B (356 patients, control group). We used a 26Fr resectoscope sheath, 30-degree telescope, and bipolar resectoscope. Urethral dilatation was performed immediately before insertion of resectoscope sheath and 28Fr dilator was used. Urethral stricture after TURP was assessed by cystoscopy. Each patient was evaluated at 1 month, 3 months, and 6 months after TURP. The effect of urethral dilatation was assessed based on International Prostate Symptom Score (IPSS), peak urine flow rate, voiding volume, and post-void residual urine.
Results
There were no significant differences of clinical variables, such as prostate volume, serum prostate specific antigen (PSA), age, operation time, and duration of catheterization between two groups (p>0.05). However, peak urine flow rate was significantly different between group A and B (19.87±9.12 vs 16.18±9.79, p=0.047). The incidence of urethral stricture after TURP was 4.06% (12/295) and 8.71% (31/356) in group A and B, respectively (p=0.032).
Conclusions
We suggested that the routinely urethral dilatation before TURP is simple and effective way to prevent urethral stricture after TURP for BPH.
