Although the surgical procedure for the treatment of benign prostatic hyperplasia with mesh stent is simple and minimally invasive, it is in principle suitable for any patient with benign prostatic hyperplasia who has symptoms of lower urinary tract infarction, especially for high-risk patients with severe systemic complications who cannot tolerate surgical treatment.
However, it should be noted that there are also contraindications to using mesh stent for the treatment of benign prostatic hyperplasia, and the following patients with benign prostatic hyperplasia accompanied by several conditions are not suitable for this treatment method.
Hyperplasia of the middle lobe of the prostate
"When simple or predominantly medial lobar hyperplasia occurs, the proliferative tissue tends to protrude into the bladder lumen, and the reticular stent is not easy to support the tissue that protrudes into the bladder, and is prone to displacement to the distal urethra, making it unsuitable for this treatment.".
Prostate urethra too short
When the length of the prostate urethra is less than 2 centimeters, the stent is not easily fixed in the urethra.
urethral stricture
When patients with benign prostatic hyperplasia complicated with urethral stricture or bladder neck contracture, the obstruction should be resolved before stent placement is considered.
Urinary system infection
Patients with benign prostatic hyperplasia accompanied by urinary system infection should receive stent placement after infection control.
bladder stone
Patients with benign prostatic hyperplasia complicated with bladder stones should be treated for bladder stones before or at the same time as stent implantation.
Bladder tumor
Patients with benign prostatic hyperplasia complicated with bladder tumors should also be carefully selected to avoid cystoscopy affecting the placement of the stent within 6 months.
Patients with diabetes or hemorrhagic disease
Patients with benign prostatic hyperplasia accompanied by diabetes or bleeding diseases should carefully choose this treatment.
Long term indwelling catheter
For patients with benign prostatic hyperplasia who have been indwelling catheters for a long time, it is best to perform stent placement treatment one week after switching to suprapubic cystostomy, because patients with long-term indwelling catheters have urethral mucosal edema, and stent placement can easily lead to bleeding, which affects observation and increases the chance of manual surgery failure.
