Urethroplasty with circular fasciocutaneous flap in the treatment of complex anterior urethral strictures / 中华整形外科杂志

<p><b>OBJECTIVE</b>To summarize the experience of urethral reconstruction using circular fasciocutaneous flap for the treatment of complex anterior urethral strictures.</p><p><b>METHOD</b>The circular fasciocutaneous flap was harvested from the distal penile shaft or foreskin. Then the circular configuration was converted into longitudinal strip of skin which was rotated to ventral side to repair the exposured urethral strictures using the ventral onlay method. The surveillance protocol after urethroplasty was urination observation, regularly uroflowmetry and urethrography examination.</p><p><b>RESULTS</b>From Nov. 2006 to Oct. 2012, 15 cases were treated. The mean age was 45 years (20-76 years) and mean follow-up period was 18 months(3 months-3 years). Stricture was caused by chronic urethritis in 4 cases, long-term urethral catheterization in 3 cases, transurethral perfusion chem other aphy in 3 cases, transurethral prostatectomy in 3 cases and hypospadias after surgery in 2 patients. The mean stricture length was 7.0 cm (3.5-12.0 cm). The overall success rate was 80.0% (12/15). Recurrence stenosis was noted in 2 cases and diverticulum formation in 1 case.</p><p><b>CONCLUSIONS</b>The penile circular fasciocutaneous flap can be used for anterior urethral stricture in nearly any length. The flap has the characteristics of hairless, adequate mobile and length, well-vascularized pedicle and easy to harvest. The onlay reconstruction provides excellent cosmetic results, less trauma, higher success rate. Therefore it should be one of the preferred techniques for complex anterior urethral stricture repair.</p>

High-frequency color Doppler ultrasonography: valuable for diagnosis of polyorchidism / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the application value of high-frequency color Doppler ultrasonography in the diagnosis of polyorchidism.</p><p><b>METHODS</b>We retrospectively studied 6 cases of polyorchidism diagnosed by ultrasound, 5 of which were pathologically confirmed, and analyzed the sonographic and clinical findings.</p><p><b>RESULTS</b>All the 6 cases were triorchidism, 4 located in the scrotum, and 2 in the same groin with indirect hernia. The supernumerary testis was linked to the epididymis in 3 cases, 1 accompanied with repeated epididymis and vas deferens, and 2 connected to no vas deferens and epididymis. Color Doppler ultrasonography revealed blood flow signals in 4 cases, but not in the other 2.</p><p><b>CONCLUSION</b>Polyorchidism has typical sonographic appearances, and high-frequency color Doppler ultrasonography plays an important role in its diagnosis.</p>
