Objective To explore the clinical effect of color Doppler ultrasound guided small incision in repairing penile fracture.Methods Sixteen cases of penile fracture single cavernosum rupture adopted the preoperative positioning by color Doppler ultrasound,hematoma removal and albuginea repair.The clinical effect was evaluated after operation.Results The albuginea rupture was smoothly found in 15 cases,1 case was converted to coronary sulcus annular degloving incision.The operation time was 20-60 min with a mean of 35 min;the postoperative hospital stay was 3.0-6.0 d with a mean of 4.8 d;the catheter removal was on postoperative 3-5 d,urination was unobstructed.Follow up lasted for 6-12 months,1 case appeared transient erectile dysfunction,the harden was touched during erection in 1 case,and other cases had no obvious complication occurrence.Conclusion The color Doppler ultrasound can locate the rupture of corpora cavernosa penis and albuginea.Selecting color Doppler ultrasound guided small incision in repairing penile fracture has small trauma and less complications,and can get satisfactory effect.
