On February 21, the general interventional ward of our hospital performed prostate stenting for an elderly patient who had difficulty urinating due to prostate enlargement and was unwilling to undergo surgery, helping him to relieve the difficulty in urination. The patient was diagnosed with prostatic hyperplasia, urinary retention, bilateral hydronephrosis, renal insufficiency and many other urological diseases by the Department of Urology, and was routinely catheterized. The patient’s quality of life was seriously affected because he had to carry the urinary catheter and drainage bag even when he was discharged home for Chinese New Year. The difficulty in urination and the repeated removal and insertion of urinary catheters left a serious shadow in Mr. Huang’s heart, and he could not get out of the dilemma of difficulty in urination even after tossing and turning. Conservative treatment is ineffective, and long-term indwelling urinary catheter is prone to infection. When Dr. Lei Yu, chief physician of the general interventional ward, mentioned to Mr. Huang the method of placing a urethral stent in the urethra to solve the difficulty in urination, he seemed to see a new hope, and after careful inquiry and full understanding of the urethral stent, Mr. Huang gladly accepted this minimally invasive treatment plan. After urography, it was seen that there was a limited stricture in the prostate segment of his urethra, with a length of about 3.3 cm and a stricture of about 70%. After several measurements and careful adjustments, a custom-made prostatic urethral stent was successfully placed into the urethral stricture, and the difficulty in urination that had been bothering Mr. Huang for more than a month was then resolved. The enlarged prostate narrowed the urethra, which in turn caused a series of complications such as difficulty in urination and even urinary retention. This is because these patients are older and often have a variety of underlying diseases that make them reluctant to undergo surgical procedures. According to Yu Lei, director of the general interventional ward, interventional radiology methods have been used for the treatment of urethral strictures and ureteral strictures caused by various reasons such as prostate enlargement and tumors. Interventional treatment methods have the advantages of lower risk of anesthesia and surgery, no destruction of tissues and organs, short operation time and hospital stay, fewer serious complications, less relative cost, and easy acceptance by patients who can walk and move after surgery. It can rapidly improve the quality of life of patients, especially for patients of advanced age, high risk and those who do not want to undergo organ removal surgery, and can be the preferred treatment method.
