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.
Objective To investigate the safety, efficacy and morbidity of onestage urethroplasty by using bladder mucosa for treatment of hypospadias. Methods From August 1991 to August 2003, 38 cases of congenital hypospadias were given bladder mucosa flap procedure and one stage urethroplasty. Results Thirty-eight cases of hypospadias treated with one stageurethroplasty by using bladder mucosa were followed up 6 months-9 years afterthe procedure. The success rate of the operation was 95%. Three cases of urethral fistula after the procedure were surgically repaired again, 2 cases of urethral stricture recovered after distension. The complication markedly lessened, micturation became normal with the reconstructed meatussituated at the proper site on the glands. Conclusion one stage urethroplastyby using bladder mucosa for treatment of hypospadias is a simple, effective andsafe surgery.
ObjectivTo investigate the incidence of depression and its etiological factors in patients with hypospadias after operation. MethodsFrom January to June 2015, we investigated the incidence of depression symptoms among patients with hypospadias after surgical treatment from January 1990 to December 1994 in Zhangzhou Affiliated Hospital of Fujian Medical University, and we matched them with mentally healthy adults of the same age to 1:1 ratio. Zung Self-Rating Depression Scale and Correlation Factor Questionnaire were used to investigate and analyze the related factors of depression symptoms between the patients with hypospadias and the healthy males. ResultsA total of 80 patients with hypospadias after surgical treatment and 80 healthy males as control were included. There were no significant differences in male secondary sexual development, testis development, serum testosterone levels and postoperative length and girth of the penis in two groups. The incidence rate of depression symptoms was 45.0% (16/80) in the hypospadias patients after operation, extremely significantly higher than 6.3% (5/80) in the control group (χ2=6.632, P=0.01). The result of multiple stepwise regression analysis showed that the main risk factors of depression symptoms were worries about dissatisfaction with penile and scrotal appearance (F=16.210 3, P=0.001), sexual satisfaction (F=4.621 2, P=0.036) and sexual function (F=4.103 2, P=0.043). ConclusionSymptoms of depression often occur in hypospadias patients after operation, and the major etiological factors are dissatisfaction with penile and scrotal appearance, sexual satisfaction and sexual function.
Objective To search for a new method to repair distal urethral stricture resulting from urethroplasty of hypospadias. Methods FromFebruary 2000 toMarch 2004, 16 patients with distal urethral stricture were treated by use of cutting stricture urethra and their distal urethra were reconstructed with phallic flap. Results All operations were successful without complication of flap necrosis. After 7 days of operation, the patients had free micturition and thick stream of urine. Eleven patients were followed 2 months to 4 years, the satisfactory result was obtained. Conclusion It is a simple and good method to reconstruct the distal urethra by superimposing the phallic flap on the cut stricture urethra after urethroplasty of hypospadias.
Objective To assess the analgesic effect of caudal bupivacaine with neostigmine for hypospadias surgery in children. Methods We searched The Cochrane Library (Issue 2, 2008), MEDLINE (1966-2008), EMbase (1980-2008), CBMdisc (1978-2008), CNKI (1989-2008) and Wanfang Database using the keywords “bupivacaine”, “neostigmine” and “hypospadias” to identify randomized control trials (RCTs) of caudal bupivacaine with neostigmine versus bupivacaine alone for hypospadias surgery in children. The methodological quality of included RCTs was evaluated by two reviewers independently, and Meta-analysis was conducted using RevMan 5.0.13 software. Results We identified 3 RCTs including 160 patients which had an uncertain risk of bias. The results of meta-analysis showed no significant difference found between bupivacine alone and bupivacine plus 1 µg/kg neostigmine (WMD= 0.05, 95%CI – 6.76 to 6.86, P= 0.99), but a difference was found between bupivacine alone and bupivacine plus 1 µg/ kg, 2 µg/kg, or 3 µg/ kg neostigmine (WMD= 12.79, 95%CI 10.96 to 14.62, Plt; 0.000 01; WMD= 12.10, 95%CI – 6.76 to 6.86, Plt; 0.000 01; WMD= 11.90, 95%CI 9.17 to 14.63, Plt;0.000 01). The duration of postoperative analgesia of the bupivacaine with neostigmine group was longer than that of bupivacine alone. Conclusions Because of the small sample size and the unclear risk of bias in the included RCTs, the effectiveness of caudal bupivacaine with neostigmine for postoperative pain management after hypospadias surgery in children is not completely confirmed. So more large sample size, double-blind RCTs are needed.
Objective Anthropometric variants in prepubertal boys with hypospadias were assigned and assessed to illustrate anatomical malformation. Methods A total of 516 prepubertal (Tanner grade Ⅰ) boys with hypospadias who were admitted to three medical centers between March 2021 and December 2021 and met the selection criteria for primary surgery were selected. The age of the boys ranged from 10 to 111 months, with an average of 32.6 months. Hypospadias were classified according to the location of the urethral defect, 47 cases (9.11%) of the distal type (the urethral defect is in the coronal groove or beyond), 208 cases (40.31%) of the middle type (the urethral defect is in the penis body), and 261 cases (50.58%) of the proximal type (the urethral defect is at the junction or proximal side of the penis and scrotum). The following indexes were measured: penis length before and immediately after operation, reconstructed urethral length, and total urethral length. Morphological indicators of the glans area, including preoperative height and width of glans, AB, BC, AE, AD, effective AD, CC, BB, the urethral plate width of the coronal sulcus, and postoperative height and width of glans, AB, BE, and AD. In which point A is the distal endpoint of navicular groove, point B is the protuberance lateral to the navicular groove, point C is the ventrolateral protuberance of the glans corona, point D is the dorsal midline point of the glans corona, and point E is the ventral midline point of the coronal sulcus. The foreskin morphological indicators, including the foreskin width, inner foreskin length, and outer foreskin length. The scrotal morphological indicators, including the left, right, and front penile to scrotum distance. The anogenital distances, including anoscrotal distance 1 (ASD1), ASD2, anogenital distance 1 (AGD1), and AGD2. ResultsThe penis length of the distal, middle, and proximal types decreased successively before operation, the reconstructed urethral length increased successively and the total urethral length decreased successively, these differences were all significant (P<0.05). The height and width of the glans of the distal, middle, and proximal types significantly decreased successively (P<0.05), but the height/width of the glans was generally close; AB value, AD value, and effective AD value significantly decreased successively (P<0.05); there was no significant difference in BB value, urethral plate width of the coronary sulcus, and (AB+BC)/AD value between the groups (P>0.05). There was no significant difference in the width of glans between the groups after operation (P>0.05); AB value and AB/BE value increased successively, and AD value decreased successively, these differences were all significant (P<0.05). The inner foreskin length in the 3 groups significantly decreased successively (P<0.05), while the outer foreskin length had no significant difference (P>0.05). The left penile to scrotum distance of middle, distal, and proximal types significantly increased successively (P<0.05). ASD1, AGD1, and AGD2 significantly decreased from distal type to proximal type successively (P<0.05). The other indicators’ differences were significant only between some groups (P<0.05).Conclusion The anatomic abnormalities of hypospadias can be described by anthropometric indicators, which can be used as the basis for further standardized surgical guidance.
Objective To investigate the effect of ventral urethroplasty for postoperative anastomotic stricture in patients with hypospadias. Methods From August 2000 to December 2005, 20 patients with anastomotic stricture after hypospadias repair were treated with ventral urethroplasty. The age ranged from 2 to 27 years with an average of 6.4 years. All patients showed dysuria after operation. Main clinical manifestation included dysuria and acraturesis. Interruption of urinary stream occurred in 17 cases; of them, 3 cases had urinary stasis and 4cases had frequent micturition, urgent micturition and pain in urination. Urethrography and cystourethrography showed 0.5-1.0 cm stricture with proximal dilat ion of urethra in 16 cases and obvious diverticularization in 9 cases. Urine routine examination showed that white blood cell was ++ to ++++ in 16 cases and pus cell was ± to++ in 13 cases.Results Twenty cases were followed up 2 months to 4 years (mean 2.3 years). All the cases achieved good results in urination with normosthenuria and normal force of urinary stream. No recurrent stricture, urethrocutaneous fistula, or penile curvature occurred. The cosmesis was satisfactory, and the results of urine routine examination was normal. Conclusion Ventral urethroplasty for postoperative anastomotic stricture inpatients with hypospadias is a simple and effective procedure.
ObjectiveTo discuss the reoperation methods of urethral stricture after urethroplasty of hypospadias and their effectiveness.MethodsBetween September 2010 and April 2018, 169 patients with urethral stricture after urethroplasty of hypospadias, who underwent ineffective conservative treatments first, were accepted. The age ranged from 1 year and 7 months to 41years with a median age of 5 years and 8 months. The stricture located at the external urethral orifice in 80 cases, internal anastomosis connection in 87 cases, and constructed urethra in 2 cases. The symptoms of urethral stricture occurred at 2 weeks to 52 months after urethroplasty, with a median time of 4.5 months. The patients with external urethral orifice stenosis were treated with urethral meatus augmentation (74 cases) and urethral advancement (6 cases). The patients with internal anastomosis connection stenosis were treated with internal urethrotomy with urethroscopy (10 cases), urethrotomy and one-stage urethroplasty (26 cases), and urethrostomy (51 cases) including 43 cases of two-stage urethroplasty. The patients with constructed urethral stricture were treated with urethrolysis.ResultsOne hundred and fifty-four patients were followed up 6–86 months with an average of 47 months. The stenosis was relieved in 137 cases, and re-stenosis in 12 cases, urethral fistula in 4 cases, all of which were treated successfully. In addition, 1 case with mild urethral diverticulum did not need to be treated.ConclusionIf it is ineffective for the conservative treatment of urethral stricture after urethroplasty of hypospadias, appropriate surgical treatments could be selected according to the location and length of the stricture, local tissue conditions, complications, and so on.
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.
