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.
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 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.
Objective To present the experience of hypospadias repair using the tubularized incised plate urethroplasty (Snodgrass procedure). Methods FromMay 2001 to November 2004, 82 patients with hypospadias underwent the Snodgrassprocedure and the clinical data were analysed retrospectively. The mean age was5 years (1.5 to 16 years). These cases were divided into: the earlier stage group(34 cases) and the later stage group (48 cases); the proximal group (19 cases)and the distal and middle group (63 cases); the primary operational group (49 cases) and the reoperational group (33 cases). Results Fistulas ocurred in 12 patients (14.6%), complete glans dehiscednce in 1 case. Fistula were as follows: 11 cases in the earlier stage group (32.4%) and 1 case in the later stage group（2.1%）;2 cases in the proximal group (10.5%) and 10 cases in the group of distal and middle group (15.9%); 8 cases in the primary operational group (16.1%) and 4 cases in the reoperational group (12.1%). There was statistically significant difference in the incidence of fistula between the earlier stage group and the later stage group (Plt;0.01). There was no statistically significant difference between the proximal group and the distal and middle group, between the primary operational group and the reoperational group (Pgt;0.05). All patients were followed up more than one month. The neo meatus was innormal position. The results of penile cosmetic and urethral function were satisfactory. Of these cases, 15 were followed up 1.5-6.0 months. The average flow rate was 7.8 ml/s(6.8-10.5 ml/s). The mean of maximum flow rate was 10.5 ml/s (8.8-14.5 ml/s).Conclusion Excellent neourethrol functional and superior casmetic resalts with low rate of complication can be gained by using tubularized incised plate urethroplasty for the cases of hypospadias without chordee or with mild chordee. But the preputialflap procedure should be chosen in condition that the hypospadias was association with obvious chordee.
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 comparatively analyze the effect of one-stage nonstented tubularized incised plate urethroplasty (TIP) on operative pain and compl ication by comparing with urethral catheter and urethral stent drainages. MethodsBetween March 2010 and June 2013, 214 cases of distal and mid-shaft hypospadias underwent TIP, and the cl inical data were analyzed retrospectively. The patients were divided into 3 groups based on different urinary drainage techniques: indwell ing urethral catheter was used in 68 cases (group A), indwell ing urethral stent in 70 cases (group B), and nonstented drainage in 76 cases (group C). There was no significant difference in age, hypospadias type, and accompany malformation among 3 groups (P>0.05). At 2 days after operation, Wong-Banker facial scale (WBS) and Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) were used for pain and praxiology assessment. The complications after operation also were observed and compared among 3 groups. ResultsAll patients were followed up 6-25 months (median, 11.8 months). At 2 days after operation, the median WBS scores were 4.0 (0-10), 3.5 (0-10), and 3.0 (0-10) in groups A, B, and C, respectively; median CHEOPS pain scores were 6.0 (1-13), 6.0 (1-13), and 4.0 (1-11), respectively. The WBS pain score and CHEOPS pain score in group C were significantly lower than those in groups A and B (P<0.05), but there was no significant difference between group A and group B (P>0.05). The postoperative complication occurred in 27 cases (39.7%) of group A, 29 cases (41.4%) of group B, and 13 cases (17.1%) of group C; two or more than two complications occurred in 14, 15, and 9 cases, respectively. There was significant difference in total incidence of postoperative complication among 3 groups (P<0.05). The incidences of postoperative overactive bladder, bladder spasms, urinary tract infection, and fistula in group C were significantly lower than those in groups A and B (P<0.05). There was no significant difference in incision infection, acute urinary retention, urinary extravasation, meatal stenosis, and urethral stricture among 3 groups (P>0.05). ConclusionOne-stage nonstented TIP is suitable for distal and mid-shaft hypospadias and could reduce postoperative pain and complications compared with the traditional postoperative indwell ing urethral catheter and indwell ing urethral stent.
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 To explore the feasibility of one-stage repair of hypospadias using the meatalbased flap overlapping with buccal mucosal graft. Methods From March 2002 to May 2004, 21 patients with hypospadias were treated with the meatal-based flap overlapping with buccal mucosal graft. Their ages ranged from 14 months to 8 years. The procedure were as follows:urethralplate at proximal corona was cut to correct glandular tilt and chordee; the buccal mucosa taking from inner cheek was then fixed on tunica albuginea of ventral shaft with suture; and the meatalbased flap was rotated distally and overlaid with buccal mucosal graft to repair urethra.Results All patients were followed up 318 months (7 months on average). A cosmetic glans and a vertically oriented, normal appearing slit meatus were achieved. Two patients had fistulas on lateral corona. Fistula spontaneously healed in 1 case and the other one was repaired after 6months. Conclusion The technique of meatal-based flap overlapping with buccal mucosal graft can completely correct glandular tilt and chordee, prove good cosmetic and functional glans and meatus.
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.
ObjectiveTo explore the short-term effectiveness of hypospadias repairs with free inner prepuce tube. MethodsForty-two males with hypospadias were repaired with free inner prepuce tube between May and October 2015. The age ranged from 1 year and 1 month to 28 years and 2 months with a median of 2 years and 9 months. Initial operation for hypospadias was performed in 41 cases and re-operation in 1 case of chordee after 16 months of hypospadias repair. There were 36 cases of hypospadias (6 cases of proximal penile type, 1 case of penile scrotal type, 26 cases of scrotal type, and 3 cases of perineal type) and 6 cases of typeⅣchordee according to Donnahoo classification criteria. ResultsThe length of reconstructed urethra was 2.0-5.5 cm (mean, 3.6 cm). The patients were followed up 6-10 months (mean, 8 months). Urinary fistulae was noted in 10 patients, which healed spontaneously in 5 cases within 3 months after surgery, and was cured after repair in 5 cases. Urethral stenosis occurred in 4 cases (2 external orifice stricture and 2 distal urethral stricture) and urethral incision was performed. Wound infection was noted in 3 cases, 2 of them needed further surgery for a permanent fistula. Skin ischemic necrosis was found in 3 cases, 1 of them had infection and fistula, and needed further surgical repair. Diverticulum of scrotum developed in 1 case. Ten patients need re-operation, and the success rate was 76.2% (32/42). At 3 months after surgery, the HOSE score ranged from 11 to 16 (mean, 14.7). The maximum urinary flow rate was 1.9-28.4 mL/s (mean, 10.5 mL/s) in 22 cases of outpatient at 3 months after surgery. ConclusionFree inner prepuce tube can survive and play a role of normal neourethra. The short-term effectiveness has shown a relatively high complication rate and suggests this procedure should be carefully applied.
