Abstract

Purpose

To present our preliminary experience in managing patients with highly recurrent bladder neck contractures (BNCs) after transurethral resection of the prostate (TURP).

Methods

Between February 2015 and March 2018, 28 patients with highly recurrent BNCs who had failed multiple prior to endoscopic treatments were managed with transurethral resection and intra- and post-operative triamcinolone acetonide injections. The scar tissue was resected to the circular fiber at the bladder neck, and triamcinolone acetonide (2 mL, 40 mg/mL) was injected at the incision sites (8 points) using a cystoscopic injection needle. The cystoscopy-guided injections were repeated every four weeks for total three times after surgery. The patients were followed up at 3, 6, 12 months after surgery, and in July–August 2019.

Results

The recurrent interval before the treatments was 2.2 ± 1.2 months, without any BNC recurrence in the first 12 weeks after transurethral resection. The urinary flow rate increased significantly and was maintained during the follow-up period. Adequate voiding function was reported in 25 of 28 patients at a median follow-up of 2.8 (1.7, 3.9) years. One of the three patients with decreased urinary flow rate had underactive detrusor and no BNC recurrence. The complications were mild and tolerable.

Conclusion

Transurethral resection of the scar tissue combined with intra- and post-operative triamcinolone acetonide injections resulted in a success rate of 92.9% in patients with highly recurrent BNC following TURP. It is a simple, safe, and effective treatment for highly recurrent BNCs.
