980 nm diode laser vaporization for benign prostatic hyperplasia / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the efficacy and safety of 980 nm diode laser vaporization in the treatment of benign prostatic hyperplasia (BPH).</p><p><b>METHODS</b>We treated 92 BPH patients by 980 nm diode laser vaporization. The patients were aged 65 - 89 years, with a mean prostate volume of (50.1 +/- 13.0) ml. We analyzed and compared the mean operation time, intra-operative blood loss, postoperative complications, international prostate symptom score (IPSS), quality of life (QOL) score, maximum urine flow rate (Qmax), and post void residual (PVR) before and after surgery.</p><p><b>RESULTS</b>Operations were successful in all the 92 cases, with an average operation time of (70.2 +/- 16.9) min, very little blood loss and no blood transfusion. The transurethral catheter indwelling time was 2 -5 (2.4 +/- 0.3) days. The patients were followed up for 1 to 3 months, which revealed a significant reduction in IPPS (P < 0.01) and improvement in Qmax and PVR (P < 0.01) as compared with preoperation. No severe complications were reported, including urinary incontinence and bladder irritation symptoms. None of the patients complained of impaired erectile function.</p><p><b>CONCLUSION</b>Transurethral 980 nm diode laser vaporization is a safe and effective treatment for BPH.</p>

Analysis of the risk factors of upper urinary tract dilatation due to spinal cord injury / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the urodynamic risk factors of upper urinary tract dilatation (UUTD) secondary to spinal cord injury (SCI).</p><p><b>METHODS</b>Ninety-six SCI patients of Tangshan earthquake were divided into 2 groups by ultrasonography: 16 SCI patients (group A) with UUTD and 80 SCI patients (group B) without UUTD received urodynamic test. Responses were evaluated using single and multiple analysis after examination.</p><p><b>RESULTS</b>The incidence of male was significantly higher than that of female. Residual urine volume, maximum cystometric capacity, detrusor leak point pressure and the incidence of bladder low compliance in group A were significantly higher than those in group B. There were no significant differences in age, the incidence of detrusor hyperreflexia, relative safe bladder capacity, the incidence of detrusor-sphincter dyssynergia, maximum flow rate and maximum urethral closure pressure between 2 groups. Bladder low compliance was cardinal risk factors according to Logistic regression analysis.</p><p><b>CONCLUSION</b>An early urodynamic examination and treatment for SCI patients are important to prevent from bladder low compliance and upper urinary tract damage.</p>
