designed to be 12e14 cm in length and 14e16 cm in width,with the artery and its branch for axis. It includesthree parts; part A flap is 3.0e3.6 cm wide and is used forurethral reconstruction.

The part B flap is used as de-epidermis for the gapbetween the reconstructed urethra and the penis body. Thepart A flap is overturned for the inner skin, and the part Cflap is also overturned for the penis shaft (Fig. 3). The distaledge of the part A flap is then sutured to that of the part Cflap to form a new urethral orifice. The new glans is recon-structed by local shaping (Fig. 4). The next step is anasto-mosis of the new partial urethra to the old urethralorifice with a Folly’s catheter in it. A malleable penile pros-thesis with silver silica gel is inserted into the reconstructedpenis. Its proximate part is fixed to the pubic periosteum.The donor vessel and receipt vessel are anastomosed usinga microsurgical technique. This closes the incision.

Figure 1 Design of flap.

Postsurgical procedures include 2 weeks of bed rest withthe penis elevated, frequent inspection of the flap, anti-coagulation medication and prevention of infection.

In obese patients, free skin graft or scrotal septum flapcan be used for urethral reconstruction to prevent a bigshaft or insufficient blood flow to the new urethra. Re-construction of the glans is achieved by split thickness skingraft transplantation in the distal part of penis.

Clinical results

Of the 15 procedures that were included in this study, 14were successful, with favourable cosmetic and functionalresults. One patient experienced failure due to venousthrombus, which was probably due at least in part to his 20-year smoking habit (Table 1).

Case 1

The patient, a 30-year-old, was burned 2 years ago byelectric shock. His penis was completely severed but hisscrotum, testicles and varicosity were left intact. It wasreadily apparent that the scar on his perineum had alreadybecome soft (Fig. 5). One year after undergoing penis re-construction with free scapular skin flap and a malleablepenile prosthesis implantation, he has satisfying erectionsand good cosmetic results, but he has not married (Figs. 6and 7).

Discussion

The advantages of the free scapular flap include ampletissue, invariable vessel direction, abundant blood supplyand less deformity. The scapula may be used for penis

support, but this study opted instead for a malleable penileprosthesis because of the difficulty of shaping bone. Theinferior epigastric vessel has a long pedicle, adequatediameter and invariable vessel direction, therefore it wasselected as the recipient vessel.

The sensory nerves of the scapular flap are the innerbranches of the posterior branches of two to four pectoralnerves. It is difficult to transfer the scapular flap withsensory nerves because they are detached from the vesselwith several branches. But this study revealed the flapregained sensitivity after 6 months. The extent of recoveryof sensitivity after was 3e4 cm below the top of the flap.The testing included perception of pain, feelings and two-point discrimination. Exploration is under way for a methodof scapular flap transplantation with neurovascular pedicle.

There are many methods for penis reconstruction.1e10

The forearm flap method, which is similar to the free scap-ular flap, is common but has some disadvantages, such asthin subcutaneous tissue, less tissue for transfer, thin re-constructed penis, lost forearm trunk vessel and reductionof muscular power. It is also inadequate for the patient withmore hair on the forearm. The advantage of the forearmflap is that it has good sensory nerves for its neurovascularpedicle.

Another method, the combined inguinal osseocutaneousflap, which is applied with a flap of pedicled superficialcircumflex iliac vessel combining iliac bone piece, has theadvantages of a hidden donor site and a simple procedurewith no microsurgical technique. But the combined flap hasdeficient blood supply for its vessel variation. The compli-cations include fat fluidity, infection and bone exposure.

Therefore the authors conclude that the free scapularflap is the preferred method for penile reconstruction.
