Combination of the ureteral dilation catheter and balloon catheter under the ureteroscope in the treatment of male urethral stricture / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the clinical application of the ureteral dilation catheter combined with the balloon catheter under the ureteroscope in the treatment of urethral stricture in men.</p><p><b>METHODS</b>Under the ureteroscope, 45 male patients with urethral stricture received placement of a zebra guide wire through the strictured urethra into the bladder and then a ureteral dilation catheter along the guide wire, followed by dilation of the urethra from F8 initially to F14 and F16. Again, the ureteroscope was used to determine the length of the strictured urethra, its distance to the external urethral orifice, and whether it was normally located. An F24 balloon catheter and then a metal urethral calibrator was used for the dilation of the strictured urethra. After removal of the F18-F22 urethral catheter at 8 weeks, the urinary flow rate was measured immediately and again at 3 months.</p><p><b>RESULTS</b>All the operations were successfully performed without serious complications. The maximum urinary flow rate was (13.3-29.9) ml/s (mean [17.7 ± 3.2] ml/s) at the removal of the catheter and (15.2-30.8) ml/s (mean [19.8 ± 3.9] ml/s) at 3 months after it. Smooth urination was found in all the patients during the 6-24 months follow-up.</p><p><b>CONCLUSION</b>The application of the ureteral dilation catheter combined with, the balloon catheter under the ureteroscope is a good option for the treatment of male urethral stricture for its advantages of uncomplicatedness, safety, effectiveness, few complications, less pain, high success rate, and repeatable operation.</p>

Modified circumcision with a disposable suture device / 中华男科学杂志

<p><b>OBJECTIVE</b>To improve the methods and reduce the complications of circumcision with a disposable suture device.</p><p><b>METHODS</b>This study included 325 male patients aged 14-65 (mean 28.9) years, treated for redundant prepuce or phimosis by modified (n = 201) or conventional circumcision with a disposable suture device (n = 124). We compared the incidence of complications and the patients' satisfaction between the two surgical methods.</p><p><b>RESULTS</b>Compared with conventional circumcision, the modified method showed a significantly lower incidence of postoperative bleeding (14.52% vs 2.49% , P < 0.05) and a lower rate of second surgery for penile hematoma (4.03% vs 0.50%, P < 0.05). The patients' satisfaction was markedly higher with the modified method (91.94%) than with conventional circumcision (97.51%) (P < 0.05).</p><p><b>CONCLUSION</b>Modified circumcision with the disposable suture device can significantly reduce the incidence of postoperative bleeding and penile hematoma and therefore deserves wide clinical application.</p>

Diagnosis and treatment of urachal remnants with heterotopia sinus: a report of 2 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>To probe into the diagnosis and treatment of urachal remnants with heterotopic sinus.</p><p><b>METHODS</b>Two cases with penis dorsal drainage for 5 approximately 6 years were diagnosed as urachal anomaly by sinus probing, methylene blue injection test, cystoscope examination, and type B ultrasonic examination, and both received surgical removal of the urachus and all the abnormal tissues associated with it.</p><p><b>RESULTS</b>Surgery and pathology proved urachal cyst with communication drainage in both of the patients. Follow-up survey showed no recurrence and malignancy.</p><p><b>CONCLUSION</b>Sinus probing, mythylene blue injection test and type B ultrasonic examination are effective methods for the diagnosis of urachal remnants with heterotopic sinus. Surgical treatment should include radical removal of the urachus and the abnormal tissues associated with it.</p>
