Abstract:

Objective: To evaluate the clinical effect and feasibility in treating urethral stricture caused by benign prostatic
hyperplasia（BPH）with transurethral implanted home-made stent under X-ray guidance. Methods: 62 cases of dysuria weth BPH treated by home -made stent were retrospectively analyzed. After 1% lidocaine urethra mucosa anaesthesia, the processes of transurethral implanted stents at the narrowest area of the urethra under X-ray guidance were performed. Results: The first-time success rate of the treating process was 98.4%（61/62）. Dysuria resolved immediately after the stent placement in 57 patients. After the successful placement of stent, IPSS decreased from（27.8±4.1）ml/s to（5.1±3.7）ml/s（P<0.01）; AFR increased from（5.1±3.7）ml/s to（12.9±4.2）ml/s（P<0.01）; Qmax increased from（1.8±3.2）ml/s to（14.2±2.8）ml/s（P<0.01）; RUV decreased from（173±28.4）ml to （54.2±23.7）ml（P<0.01) in the postoperative follow-up of 46 cases. Conclusion: The home-made stent interventional implantation is a quick, reliable and minimal invasive therapy for the dysuresia with BPH, and should be the preferred method for the senile patients who will be at risk in surgical operation.
