Introduction & Objectives:- Congenital penile curvature (CPC) is not a common congenital anomaly, with a reported incidence of 0 – 10 %. The presence of a significant untreated curvature may affect men’s social, sexual, and mental health. Many approaches; dorsal plication, ventral lengthening, penile disassembly and corporeal rotation had been described in literatures with many techniques and modifications. All of them have short and long term complications. Z- Plasty is a widely used technique in plastic surgery in scar revision and some congenital anomalies e.g. cleft libe, and post burn contracture repair. We aim in this study to evaluate the surgical and functional outcomes of ventral ZPlasty in repair of CPC. Materials & Methods:- Patients with primary CPC> 30° without hypospadias enrolled in this study after approval of our local ethics committee. After induction of artificial erection the penile chordee degree, inner and outer penile surfaces lengths were measured. The differences between the two surfaces lengths measured and the incision lengths and the number of Z-plasties needed to gap the differences calculated. The incision length equals the difference length/1.6. The number of Z plasties equals the incision length/0.5. A 60 ° Z-Plasty with 0.5 cm limbs was designed on the ventral surface of the penis. Dissection, elevation, and rotation of the flaps were done and closed with continuous 0/4 Vicryl suture. Penile straightening was confirmed by artificial erection test. Erectile function was assessed before and 6 months after surgery by International Index of Erectile Function (IIEF-5). Primary endpoint was straight penis with no or residual chordee < 5°. Secondary endpoints were change of IIEF 5 scores and surgical complications. Results:- 35 patients with CPC ranged from 35° to 100° (mean 65.29±16.4) enrolled in this study. Age range was 21- 41 years (26.46± 5.56). The length differences between the two surfaces ranged from 0.8 to 2.8 cm (1.92±0.4) and the incision lengths ranged from 0.5 to 1.75 cm (1.2±0.3). 1 to 4 Z-Plasties need to gap the length differences. Operative time ranged from 64 to 103 (73.2±9.6) minutes. All patients were followed for at least 6 months (6-23 months, 14.4±3.6). Success rate was 32/35 (91.4%). 30 patients had straight penis with no residual chordee, 2 patients had residual chordee 5° (10-15°). 2 patients (5.7%) complicated with postoperative bleeding; one of them needed surgical revision. 1 patient (2.85%) had painful nodule related to the suture. IIEF 5 score significantly improved by chordee correction from 18.34±.1 to 22.1±1.2 (P = 0.0001). Conclusions:-Ventral Z-Plasty is a good technique for CPC correction with low complication rate. It improved the erectile function mainly by improving penetration and satisfaction
