Résumé

<p><b>OBJECTIVE</b>To investigate the impact of penile surgery on the erectile function of the patient and to evaluate the role of small-dose vardenafil in restoring the impaired penile erection.</p><p><b>METHODS</b>Sixty cases of penile cavernosum surgery were equally and randomly divided into a vardenafil and a control group, the former treated 5 - 7 days after surgery with 10 mg vardenafil every other day, while the latter given vitamin E at 100 mg once a day, both for 12 weeks. The penile erectile function of the patients was evaluated with the IIEF-5 questionnaire before surgery and at 3 and 6 months after vardenafil medication.</p><p><b>RESULTS</b>The mean IIEF-5 scores of the vardenafil group were 18.83 +/- 2.98 and 20.13 +/- 2.98 at 3 and 6 months after vardenafil medication, significantly higher than 14.21 +/- 3.62 before surgery (P > 0.05), while that of the control group was significantly decreased at 3 months as compared with the preoperative score (13.38 +/- 2.82 versus 15.80 +/- 3.02, P < 0.05). The vardenafil group showed the highest IIEF-5 score after surgery (P < 0.05).</p><p><b>CONCLUSION</b>Long-term administration of small-dose vardenafil after penile surgery helps to restore and maintain penile erectile function.</p>

Résumé

<p><b>OBJECTIVE</b>To investigate the effects of surgery treatment on serious penile lesions and malformation.</p><p><b>METHODS</b>Sixty-two patients, aged from 19 to 63 years old (mean 35 ys), were included in the study. Among them, 4 patients suffered from penis partial defection were respectively treated with restoring defective penis, penis lengthening and urethroplasty; three patients with penis completely missing were treated with penis reconstruction surgery; 22 cases with serious penile curvature were treated with the 16-dot plication technique (Lue's procedure); 15 cases with penile fracture were treated with conservative treatment for 1 case and with patch penis, corpus spongiosum, and deep penile dorsal vein ligation for 14 cases; 5 cases with post-operative complications of 3-pieces of penile prosthesis, including the prosthesis perforating to the urethra, water pump failure, broken connection tube, erection angle < 60 degrees and failure to expansion the corpus cavernosum, were treated by taking out prostheses, urethral repair cracks, replacement of the prostheses, excision of fibrosis scar and re-implantation prostheses respectively. Four cases with penis complete amputation were treated with the penis replantation; three cases of avulsion injury were treated with the replantation and free flap skin; 6 with Paget's disease of penises were treated with the lesion free skin buried in the scrotum and penis.</p><p><b>RESULTS</b>All these patients were followed up for 3 months to 4 years, with the average of 9 months. Among the 4 cases of penis partial defection, 2 patients were satisfied with the penile appearance and sexual function; 1 got some satisfactory and 1 was unsatisfied. Three cases with the loss of the penis completely were satisfied with both the postoperative appearance and urination, and 1 was not satisfied. Twenty-two cases of penile curvature deformities were corrected, and one case was recurrence. Fourteen of the 15 patients with penile fracture were followed, and all got the restoration of sexual function. Among them, 5 cases with post-operative complications, including mild bending, algopareunia, subcutaneous induration, poor hardness and poor sexual pleasure, were not further treated, and another case lost; Five cases with post-operative complications of three-pieces penile prosthesis were treated successfully, and 4 of their spouses were satisfied with their sexual function after operation, only 1 of their spouse not satisfied. Among four cases with complete amputation of penis, two cases of penis were replanted successfully while two necrosis. Three cases with avulsion were treated with skin grafting successfully. All 6 cases with penile Paget's disease were followed for 2 -4 years, and free skin grafts were all survival. One patient died of brain metastases 18 months after operation and five cases were disease-free survival.</p><p><b>CONCLUSION</b>The patients should be treated based on the procedure of andrological and urological surgery, together with microsurgical, flap or skin graft technique. The urologist should design personalized surgical procedure. Most of the patient's penis shape and erectile dysfunction can be reconstructed by our procedures, but some patients can not achieve the desired appearance or function of penis. New approaches of the treatment ought to be developed to restore both of the shape and function for those severe injury of the penis.</p>

Résumé

<p><b>OBJECTIVE</b>To study the clinical effect of Duckett's procedure of one-stage urethroplasty with the transverse preputial island flap in the treatment of hypospadias.</p><p><b>METHODS</b>We retrospectively studied 20 cases of hypospadias treated by Duckett's procedure of one-stage urethroplasty with the transverse preputial island flap (Group A) from 2003 to 2007. The patients ranged in age from 2 to 22 years (mean 11.3 years). Another 30 hypospadias patients aged 7 to 34 (mean 16.1) years underwent urethroplasty with mucous membrane of the bladder (Group B) in the same period. Of the 50 cases, 13 were the penile type, 33 the penoscrotal type, 2 the scrotal type, and 2 the perineal type. Catheters were indwelled in Group A, but both cystostomy and catheter indwelling were used in Group B.</p><p><b>RESULTS</b>For Duckett's procedure, surgery succeeded in 17 cases (85%), urethra stenosis developed in 1 (5%) and urinary fistula in 2 (10%), which were successfully repaired 6 months after the operation. The mean operation frequency was 1.1 per patient. In Group B, the operation was accomplished in 2 stages and succeeded in 26 cases (86.7%), with postoperative development of urinary fistula in 3 (10%) and urethra stenosis in 1 (3.3%). The mean operation frequency was 2.1 per patient. The 2 cases of postoperative urethra stenosis were both cured by urethral sounding.</p><p><b>CONCLUSION</b>Duckett's procedure of one-stage urethroplasty with the transverse preputial island flap is effective in hypospadias repair, with a success rate close to that of other types of operations and a low rate of postoperative complications. Compared with the use of mucous membrane of the bladder, it has the advantages of one-move accomplishment and gives a better penile appearance.</p>

Résumé

<p><b>OBJECTIVE</b>To recommend the successive "Z" incision and skin flaps as a method for repairing the wound in penile lengthening procedures.</p><p><b>METHODS</b>We performed penile lengthening surgery by successive "Z" incision for 5 patients complaining of short penis, who ranged in age from 16 to 34 years (22.4 +/- 7.2), and 3 of whom had a history of urethroplasty, circumcision and penile reconstruction, respectively. The superficial suspensory ligament and part of the deep suspensory ligament of the penis were exposed and severed to release the penis, and the "Z" skin flaps sutured in a tensionless state. Drainage was necessitated by exudation and the catheter removed in 24-48 hours. The penis was wrapped up by an elastic bandage, and the stitches taken out 8-10 days after the operation.</p><p><b>RESULTS</b>We achieved a mean erectile length of 8.4 cm (range 7.8-9.2 cm) after the operation, as compared with 4. 8 cm (range 4.0-5.8 cm) before the surgery. Two students of the patients obviously became active and confident. No penile contraction was noted during the 12-48 months follow-up, and both the patients and their family members were satisfied with the outcomes.</p><p><b>CONCLUSION</b>Compared with the V-, M- and Z-incision, the successive "Z" incision and skin flaps can yield longer penile length, solve the problem of insufficient skin flap to cover the wound and reduce such complications as skin necrosis and infection. It is well worth recommending for patients complaining of short penis because of penile abnormality, post-operation scar on the penis or circumcision.</p>
