Abstract

Introduction: Congenital penile curvature can present with both uniplanar and biplanar defects, the latter of which entails more technically demanding surgery.

Aim: The study aims to demonstrate the efficacy and safety of our novel superficial tunica albuginea geometric-based excision (STAGE) technique based on multiple, small, superficial elliptical tunica albuginea excisions and geometrical principles for correcting biplanar congenital penile curvature.

Methods: The study represents a retrospective analysis of 145 patients with disabling congenital biplanar ventrolateral (n = 131; 90.3%) or dorsolateral (n = 14; 9.7%) curvature of the penis, which underwent stepwise STAGEs between June 2006 and March 2012. Multiple 3-mm elliptical excisions of the superficial tunica albuginea were performed without compromising the inner layer of the tunica albuginea, thus resulting in a stepwise correction of the curvature and improved distribution of the bending force of the curvature.

Main outcome measures: Functional outcome regarding penile straightening, erectile function, and patient satisfaction were evaluated. Furthermore, clinical data concerning the early postoperative outcome were analyzed retrospectively.

Results: The mean follow-up period was 21 months (range 6-62 months). Mean age at surgery was 23.8 years (range 15-47 years). Mean degree of curvature was 65° (range 45-90°). There was no recurrent curvature. Complete correction of the penile axis was obtained in 98.6% (n = 143). No change in erectile function according to International Index of Erectile Function-5 score was visible (P = 0.748). The mean loss of penile length was 0.7 cm (range 0.3-0.9 cm). The excellent functional outcomes resulted in a high level of patient satisfaction, including improved self-esteem, libido, sexual intercourse, and psychosexual relief. Two patients had a residual curvature of up to 30° requiring a reoperation. No intra- or postoperative complications were encountered.

Conclusions: We recommend the STAGE technique as the optimal surgical intervention for correcting both uniplanar and biplanar congenital deviations.
