Aim: To understand the risk factors associated with the incidence of bladder neck stenosis (BNS) after transurethral prostate surgery. Patients and Methods: We retrospectively reviewed 900 patients who underwent transurethral prostate surgery over a 4-year period. The mean age of the men was 72.3 (47–94) years. The specific outcome data assessed related to BNS, including type of operation performed, resected tissue weight and history of previous surgery in the lower urinary tract. Results: 29 (3.4%) patients developed BNS at a mean of 10.3 (3–33) months, with a mean resected prostatic tissue weight of 11 ± 3.7 g. Four of the 29 patients with BNS were treated with bladder neck resection and re-stenosed. Fifty-four men underwent bladder neck incision for small prostates with a high bladder neck, measured by digital rectal examination and assessed cystoscopically, with no BNS. All the remaining patients from our series did not have a BNS, with a mean resected weight of 28 ± 8.9 g, which is statistically greater than in the BNS group (p < 0.05, unpaired t test). Conclusions: BNS after transurethral prostate surgery is a significant problem. It is clear from our study that resection in small prostates with no sign of a high bladder neck will increase the development of BNS. Thus, small prostates should be managed by an initial bladder neck incision, even if the bladder neck is not high.
