Objective To investigate a method of repairing hypospadias by combining buccal mucosal graft with scrotal flap and its therapeutic effect. Methods From March 2002 to December 2007, 42 patients with hypospadias underwent primary urethral reconstruction using buccal mucosal graft and scrotal flap. The patients ranged in age from 18 months to 18 years. There were 21 cases of penoscrotal type, 12 cases of scrotal type and 9 cases of perineal type. Among them,8 cases were at initial operation, and 34 cases suffered from the failure of hypospadias repair 6-19 months (average 10 months) after initial operation. During operation, the defect of urethra was 3-7 cm (average 4.2 cm) when the penis was straightened; the buccal mucosa (3.0 cm × 1.2 cm-7.0 cm × 1.5 cm) was transplanted to the tunica albuginea in the ventral aspect of the penis, and was paired with the scrotal flap (3.0 cm × 1.5 cm-7.0 cm × 1.5 cm) to repair urethra. Results The incision of 38 cases healed by first intention, and no compl ication occurred. At 7 days after operation, 4 cases had urinary fistula at either coronary sulcus or anastomotic stoma, one of which spontaneously closed 2 months after operation and the rest 3 recovered by repairing urinary fistula 6 months after operation. All patients were followed for 3-48 months (average 18 months). Urination was smooth, the reconstructed urethral opening was at the tip of glans peins without retraction and with apperance similar to the normal urethral opening. The appearance of penis and scrotum was satisfying, and the penis was straightened completely. Conclusion Combined buccal mucosal graft and scrotal flap, with considerable tissue for uretha tract reconstruction and low incidence rate of urethral stricture, is one of the effective methods to repair hypospadias.
目的探讨腹股沟直疝突入阴囊的可能原因及其手术修补方法。 方法回顾性分析笔者所在医院2005年6月至2013年6月期间收治的353例次腹股沟直疝患者的临床资料。 结果353例次腹股沟直疝患者，发生疝囊突入阴囊12例次，发生率为3.4%。与未突入阴囊组比较，突入阴囊组患者的年龄大、病程长、疝环口及疝囊大，且多伴有慢性支气管炎、便秘等导致慢性腹内压增高的疾患。12例次中采用“疝环充填+平片”修补术1例次，其余11例次均采用腹膜前修补术。术后随访6～60个月，平均37个月，无复发病例。 结论腹股沟直疝在少数情况下可以突入阴囊，宜选择腹膜前间隙疝无张力修补术。
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 introduce a modified penile elongation method and observe its postoperative compl ications. Methods From January 1993 to December 2007, 130 patients with congenital short and small penis were divided into 2 groups: the routine group and the modified group, with 65 patients in each group. In the routine group, the patients were 18-55 years old (39.6 on average), and the penile length during erection was (4.9 ± 1.4) cm. In the modified group, the patients were 20-56 years old (35.4 on average), and the penile length during erection was (5.0 ± 1.5) cm. There was no significant difference between the two groups (P gt; 0.05). On the basis of scrotal flap which was transferred to cover the prolonged cavernous body of penis, the “+” shaped incision at the root of the penis was made in the routine group, and theincision was shifted upward by 1.5 cm in the modified group. And V-Y incision was made for the penises with more than 4 cm prolonged length. In order to compare the conditions in the two groups, no physical therapy was appl ied in 30 days after the operation. Results All the 130 patients’ incisions obtainedt heal ing by the firs intention, and all flaps survived successfully. Postoperative hydrophallus appeared differently between both groups. In the routine group, obvious hydrophallus appeared on the 3rd day after the operation and lasted for (15.11 ± 2.71) days, with 3 cases (4.62%) suffering from refractory hydrophallus. In the modified group, hydrophallus appeared on the 3rd day after the operation and lasted for (6.65 ± 0.29) days without any refractory hydrophallus. There was significant difference between the two groups in the duration of hydrophallus (P lt; 0.05). All patients were followed up for 6-8 months. After the operation, the shape and function of the penis were found good. The prolonged length was (4.9 ± 1.4) cm in the routine group and (5.0 ± 1.5) cm in the modified group. There was no significant difference between the two groups (P gt; 0.05). The satisfaction rate (according to the patients’ self-rating) was 95% and 98% in the routine group and the modified group, respectively. Conclusion The method using the scrotal flap transferred to cover the prolonged cavernous body of the penis is safe and of low compl ication rate. The modified method is more effective to abate postoperative hydrophallus.
Objective To investigate the value of applying closed continuous negative pressure drainage in preventing postoperative complications of inguinal hernia. Methods The clinical data of 107 adult male patients diagnosed with inguinal giant hernia (incarcerated 16 cases, non-incarcerated 91 cases) undergoing tension-free hernioplasty using the Ultrapro Hernia System (UHS) between April 2011 and June 2016 in our hospital were retrospective analyzed. Prophylactic use of antibiotics was not adopted except patients with incarcerated hernia, diabetes, or elderly. Multi-lateral hole plasma drainage tube were used in 61 patients, 46 cases without indwelling plasma tube. The postoperative scrotum pain, scrotal hematoma, scrotal effusion, and incision infection of two groups patients were observed. Results Of the 61 patients with plasma drainage, the mean drainage time was 2 days, the longest was 5 days. Postoperative scrotal pain was found in 2 cases (3.3%) without scrotal hematoma or scrotal effusion. Of the 2 patients, the drainage of 1 case was obstructed, the drainage was extubated and the patient was cured and discharged after 5 days by sucking the drainage tube using empty needle. The average hospital stay in this group was 4 days. Of the 46 patients without plasma drainage, 7 patients (15.2%) suffered scrotal pain, 7 patients (15.2%) suffered scrotal hematoma. The average hospital stay was 6 days. The incidence of scrotal pain and scrotal hematoma was significantly higher in patients without plasma drainage than those with drainage (P<0.05). The condition of scrotal hematoma would be improved after 1–3 times outpatient dressing change and repeated hematoma sucking. One case was not improved after repeated suction, the condition was improved after scrotum incision, drainage, and dressing. Conclusion Closed continuous negative pressure drainage potentially prevents oblique hernia pain and scrotal hematoma without increasing the incidence of incision infection or hospitalization time.
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.
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 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.
