Objective To introduce the application of the scrotal flap on reconstructing partial urethra defect. Methods From March 1998 to August 2004, 31 patients with urethra defect were treated with scrotal flap. Their ages ranged from6 to 34 years. Thirty-one patients included 8 cases of congenital deformity of urethra and 23 cases of complication of urethral fistula, urethral stenosis and phallus bend after hypospadias repair. The flap widths were 1. 2. cm in child and 2.3. cm in adult. The flap lengthwas 1. -2.0 times as much as the width. Nine cases were classified as penile type, 10 cases as penoscrotal type, 7 cases as scrotal type(3 children in association withcleft scrotum) and -cases as perrineal type because of pseudohermaphroditism.Urethroplasty was given by scrotal fascia vascular net flap to reconstruct urethra defect. Results All the flaps survived, and the incision healed well. Twenty four cases achieved healing by first intention and 7 cases by second intention. And fistula occurred and healed after 2 weeks in 1 case. 27 cases were followed up 14 years, 2 cases had slight chordee, the others were satisfactivly. Conclusion Urethroplasty with scrotal fascia vascular net flap is an ideal method for the partial defect urethra.
Objective To summarize the methods of repairingthe urethral defect in the penis of an adult and the clinical application of the island skin flaps of the scrotum septum to the reparative treatment. Methods From January 2000 to November 2005, twenty-six cases of urethral defect in penis, including 16 cases of congenital urethral defect, 6 cases of traumatic urethral defect in middle penis, and 4 cases of distal urethral defect, were repairedby the local penis fascia flaps.The island skin flaps of the scrotum septum were transferred to cover the penis wound. The pedicle contained the artery of the posterior scrotum and the artery of the anterior scrotum. The flap taken from the scrotum septum was 2.5 cm×5.5 cm in area. Results After a follow-up of 7months to 4 years, all the 26 patients had the healing of the first intention without urethral fistula, urethral narrowness or penis curvature, except 4 patients who developedinfection and leakage of urine, but the wounds healed spontaneously 2-4 weeks after operation. Conclusion The penis fascia flaps and the island skin flaps of the scrotum septum can be used to repair the urethral defect in the penis of an adult. The blood supply to the flaps is sufficient and all theflaps can survive well. A good shape and function of the penis can be obtained.
Objective To introduce an effective method to repair failed hypospadias. Methods From October 1998 to October 2002, 8 cases of failed penoscrotal junction hypospadias were repaired by repeated use of scrotal septum vesicular pedicle island flap to reconstruct urethra. The patientsranged in ages from 4 to 8 years. Results All flaps in 8 patients survived, the reconstructed urethra was big and smooth. After a follow up of 6-12 months, the satisfactory appearance and normal urinary stream were obtained. No complications were found. Conclusion This method is an effective operative procedure to repair failed hypospadias and is a simple and convenient operation.
Objective To study diagnosis, treatment and rebuilding of scrotum gangrene. Methods From January 1992 to September 2004, 15 patients with scrotum gangrene were treated and their clinical data were analysed.Their ages ranged from 23 to80 years. The results of bacterial culture were positive for wound sample in 14 cases and for blood in 1 case. All the patients underwent surgical treatment including incision,aggressive debridement,drainage,irrigation and antibiotic therapy. Two patients accepted hyperbaric oxygen therapy. All the patients received scrotum rebuilding by transfer of skin flap, skin grafting and suturation and orchectomy was given in 2 elder patients. Results All the patients received healing by first intention after 21 to 34 days.There was no death. Aftera follow-up of 1 to 3 years, the appearance of scotum was satisfactory and no orchiatrophy occurred. Thirteen patients with testicles had normal sexual function. Conclusion After a definite diagnosis,early aggressive debridement,broad-spectrum antibiotics and sufficient local drainage should be used. If available,hyperbaric oxygen therapy may be used to promote healing of tissue wound. Scrotum should be rebuilt based on different conditions.
Objective To investigate the effect of scrotal septum vascular pedicle flap with two wing-l ike spl itthickness skin graft in reconstructing urethra in patients with hypospadias and in reducing the compl ications. Methods From January 2007 to March 2008, 30 cases of hypospadias were treated, with a median age of 10 years (2-20 years). There were 13 cases of proximal shaft type, 12 cases of penoscrotal type and 5 cases of scrotal type. There were 8 cases with operation history. The flap size ranged from 4.0 cm × 0.8 cm to 9.0 cm × 1.0 cm and 5 mm with two wing-l ike spl it-thickness skin graft.When the downward curvature corrected, length of the flap could be determined by the length of the urethra that neededto be reconstructed. Results All flaps survived. The incision healed by first intention in all patients except one whose incision healed after change dressing because of frequent erection. Incision at donor site healed well. Eighteen patients were followed up for 6-12 months, including 8 with second operation history. The reconstructed urethras were unobstructed and no urethrostenosis or urinary fistula happened. Conclusion This is an improved technique of the scrotal septum flap in urethra reconstruction. It takes advantages of both flap and spl it-thickness skin graft in reconstructing urethra and avoides the disadvantages of a single tissue. It is a good choice for treating hypospadias whose urinary meatus locates neighborly to penoscrotal junctional zone.
ObjectiveTo investigate the effectiveness of penile up transfer method in the treatment of penoscrotal transposition (PST) in children. Methods A clinical data of 46 children with PST admitted between January 2015 and March 2021 and met selective criteria was retrospectively analyzed. The M-shaped scrotal flap method was adopted in 21 cases (group A), and the penile up transfer method was adopted in 25 cases (group B). There was no significant difference in age and PST typing between the two groups (t=0.491, P=0.626; χ2=0.710, P=0.790). The operation time and postoperative complications of the two groups were recorded and compared, and the correction effect of PST was evaluated. Results All operations were successfully completed, and no urethral injury occurred during operation. The operation time was significantly less in group B than in group A [(70.36±9.76) minutes vs. (96.62±13.18) minutes; t=7.553, P=0.000]. All children were followed up 6-33 months (mean, 13.2 months). There were 5 cases (23.8%) of skin necrosis and 6 cases (28.6%) of scar hyperplasia in group A, and 1 case (4.0%) of skin necrosis and 1 case (4.0%) of scar hyperplasia in group B. The incidence of complication was significantly lower in group B than in group A (χ2=3.949, P=0.047; χ2=5.341, P=0.021). In the evaluation of PST correction at 6 months after operation, there were 15 cases of complete correction and 6 cases of incomplete correction in group A, 24 cases of complete correction and 1 case of incomplete correction in group B, and the difference was significant (χ2=5.341, P=0.021). Conclusion The penis up transfer method is not only easy to correct PST, but also can correct scrotal separation at the same time, with fewer postoperative complications and satisfactory correction effect of penile scrotal appearance.
OBJECTIVE: To investigate the surgical approach to repair hypospadias. METHODS: From 1992 to 2000, 42 cases with hypospadias accepted secondary urethroplasty after primary operation, which included urethral burying in penile skin, bladder mucosa and scrotal septal vascular pedicled flap urethroplasty, trans-scrotal skin flap covering the wounds with normal meatus urinarius. RESULTS: Only one, out of 42 cases, had early complication of urinary fistula in 7 days after urethroplasty, which was cured by scrotal septal vascular pedicled flap urethroplasty 3 months later and had no further complication. The others were all succeeded once for all, the successful rate was 97.6%. CONCLUSION: The surgical method to repair hypospadias by urethral burying and transscrotal skin flap technique is safe, reliable and recommendable for clinical use.
Objective To evaluate the effectiveness and advantages of the wide local excision for Paget’s disease involing the penis and scrotum by comparing with the radical excision. Methods A retrospective analysis was made on the clinical data of 41 patients with Paget’s disease involving penis and scrotum who met the inclusion criteria between November 2010 and August 2015. Among them, 14 patients received wide local excision (group A), and 27 patients received radical excision (group B). No significant difference was found in age, course of disease, and lesion site between two groups (P>0.05). The recurrence rate, operative time, times of intraoperative frozen section pathology, hospitalization time, grade of wound healing, appearance and functions satisfaction were recorded and compared between two groups. Results The operative time and hospitalization time in group A were significantly shorter than those in group B (P<0.05); the times of intraoperative frozen section pathology in group A were significantly less than that in group B (P<0.05). All patients were followed up 13 to 67 months (mean, 35.5 months) in group A and 11 to 70 months (mean, 38.8 months) in group B. Grades A, B, and C wound healing was obtained in 11 cases, 2 cases, and 1 case of group A and in 12 cases, 7 cases, and 8 cases of group B respectively, showing significant difference between two groups (Z=–2.102, P=0.036). The 5-year recurrence rate was 28.6% (4/14) in group A and 22.2% (6/27) in group B, showing no significant difference (χ2=0.202, P=0.654). The score of satisfaction in appearance and functions in group A was significantly higher than that in group B (t=–2.810, P=0.008). Conclusion Paget’s disease involving penis and scrotum has a slow disease progression and good prognosis. Wide local excision can relieve symptoms effectively and obviously decrease perioperative risk in elderly patients, with no significant increase of the recurrence rate.
