Objective To summarize the cl inical effect of a new operative technique of combining penis flap with buccal mucosa graft in the treatment of phall ical urethral stricture. Methods From March 2006 to December 2007, 6 patients with phall ical urethral stricture, aged 3-26 years old, were treated by the method of combining degloved penis flap with buccalmucosa graft. All of them had the symptom of dysuria within 2-10 months after urethroplasty. The urethral stent of highelasticity sil ica was kept for 2-3 weeks after operation. Results Five patients’ incisions obtained heal ing by first intention with satisfying urination and there were no compl ications. Sl ight infection appeared in 1 case at 3 days after operation, with small quantities of suppurative exudate in the incision, which healed through open drainage and washing with antibacterial 2 weeks later. The thinning of the urinary stream was presented at 1 month after operation, and then disappeared after 2-month urethral dilatation. All the 6 patients were followed up for 6-10 months and they felt satisfied with emiction. They had a l ittle bit thicker urinary streams than those of their own age. There was not any residual urine in bladder after emiction. Conclusion The method of combining penis flap with buccal mucosa graft is effective in the treatment of phall ical urethral stricture. It deserves to be popularized due to its simple operation and credible effects.
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 anatomical features of congenital chordee without hypospadias in children and to discuss the diagnosis and treatment.Methods From August 1984 to December 2004, 94 children with chordee withouthypospadias treated in the West China Hospital of Sichuan University were classified and analyzed for anatomical alterations. Their ages ranged from 18 months to 13 years (mean 6.9 years). Ninety-four patients were divided into four groups. With intraoperation artificial erection, the patients with penis straightened after degloving were classified as type Ⅰ patients (skin-tethering), those with peins straightened after fibrotic tissue in Buck’s fascia released as type Ⅱ patients (dysgenetic fascia), those with normal urethra and orthoplasty failed after degloving and removing fibrotic tissue as type Ⅲ patients (corporal disproportion), and those with dysgenetic urethra tethering the corpora cavernosa as type Ⅳ patients (short urethra).Results In type Ⅰ (n=31, 32.9%) patients, the ventral skin and dartos fascia were contracted while Buck’s fascia and the urethra was normal, in some (7 cases) scrotal skin extended to the ventral portion of penis (webbed penis). In type Ⅱ (n=45, 47.9%), contracture of Buck’s fascia was evident and the thickening fibrotic tissue constituted the chief obstacle to orthoplasty, though in some skin was shortened. In type Ⅲ (n=6), the dorsal and ventral sides of the corpora cavernosa were disproportionated, and the morphologically normal urethra tightly adhered to the ventral aspect of corpora cavernosa. In some cases ventral skin and fascia were contracted, but orthoplasty could notbe achieved through releasing these layers. In type Ⅳ (n=12, 12.8%), the distal urethra was paper-thin and lacking corpus spongiosum, or dense fibrotic bandswere found to be deep to the urethra. The urethra tethered the corpora cavernosaand formed a bow-to-string relation. The overlying skin and fascia were contracted in varying degrees while none had significance in straightening the penis. After operation, the length of penis increased to 6.9 cm from 5.2 cm on average and the chordee was corrected to 1.6° from 42.6° before operation on average. The patients were followed up 1 months to 15 years. The results were satisfactory.Chordee remained in 2 cases, fistula and urethral stricture occurred in 2 casesrespectively, fistula in association with urethral stricture and diverticulum in 1 case; the operation was given again and the results was satisfactory. Conclusion Patients with chordee without hypospadias may be divided into four types depending on which layer of the ventral penis constitutes thechief contribution to chordee. A systematic approach with repeated artificial erection tests is needed in determining the classification and surgical correction.
Twenty cases of hypospadiasundergone urethro-plasty with blad-der mucosa and correction of cordein one stage surgery are reported.Sixteen of 20 cases had satisfactoryresults .Two cases with structureof anastomosis have been improvedby urethral dilatation and the othertwo cases complicated with urethral-cutaneous fistula have gradually heal-ed with prolonged diversion of cysto- tomy. The indication and techniqueof this surgery are discussed indetail.
目的探讨继发性阴茎癌的临床特点及诊治方法。方法 回顾性分析成都军区总医院全军普外中心收治的1例直肠癌术后36个月发生阴茎转移患者的临床资料，并结合国内、外46例文献报道的资料(1988~2010年)，对其发病情况、临床表现、转移途径、诊断、治疗和预后进行总结。 结果阴茎转移癌以泌尿系来源最多见（51.05%），其次为消化系统来源（36.17%）； 多发生在原发肿瘤术后5~18个月，部分表现为首发症状； 转移灶多位于阴茎体部或根部（87.23%），多表现于单发结节（48.94%），部分为多发结节（29.97%）； 25.53%伴有异常阴茎勃起； 常伴有其他部位转移（55.32%）。对单纯继发性阴茎癌不伴其他脏器转移者行部分或全部阴茎切除，术后辅以放疗、化疗和内分泌治疗能够提高治疗效果，延长生存期； 非手术治疗的患者，多因其他部位转移不能手术，绝大多数生存期在1年内。结论对阴茎出现单个或多个结节或伴有异常勃起的肿瘤患者，要考虑阴茎继发性转移的可能； 活检可明确诊断； 手术切除、辅以放化疗及内分泌治疗可延长患者的生存期。
ObjectiveTo evaluate the effectiveness of pedicled skin flap of foreskin for phalloplasty and Sugita surgical method in the treatment of complete concealed penis.MethodsThe clinical data of 46 children with complete concealed penis between January 2016 and January 2018 were analyzed retrospectively. Among which, 25 cases were treated with pedicled skin flap of foreskin for phalloplasty (group A) and 21 cases were treated with Sugita surgical method (group B) with an average age of 4.7 years (range, 2 years and 8 months to 11 years). At 3 months after operation, the concealed penis recovery was scored from three aspects of postoperative penis length (the difference of the penis length between at 3 months after operation and before operation), penis appearance, and skin appearance (the total score was 10). And the parents evaluation of satisfaction degree of penis exposure, penis appearance, and foreskin appearance after surgical correction was collected.ResultsEighteen cases (72.0%) in group A and 15 cases (71.4%) in group B were followed up with an average of 13 months (range, 3-36 months). The incisions healed well in both groups, and there was no flap dehiscence, infection, necrosis, and penile erectile dysfunction. The penile length of the two groups increased significantly at 3 months after operation (P<0.05); there was no significant difference between the two groups in terms of penis length and increased length at 3 months after operation and score of increase penis length after operation (P>0.05). No penile retraction occurred in the two groups. And there was no significant difference between the two groups in penis appearance score, but the penis appearance score, skin appearance score, and total score of group A were significantly better than those of group B (P<0.05). At 3 months after operation, the satisfaction rate of penis exposure in group A and group B was 88.9% and 80.0%, respectively, with no significant difference (χ2=0.50, P=0.48); the satisfaction rate of penis appearance was 72.2% and 53.3%, and the satisfaction rate of foreskin appearance was 94.4% and 53.3%, respectively, and the differences were significant (χ2=5.13, P=0.03; χ2=7.53, P=0.01).ConclusionBoth surgical methods are suitable for correction of complete concealed penis, and the penile length gets a satisfactory recovery. However, the lymphedema of the prepuce after Sugita surgical method is serious, which can easily lead to poor appearance of the penis after operation. In general, the effectiveness of pedicled skin flap of foreskin for phalloplasty is better than that of the Sugita surgical method.
