Intermediate-Term Outcomes and Complications of Long Segment Urethroplasty with Lingual Mucosa Grafts

We evaluated outcomes and donor site complications in male patients with complex urethral strictures who underwent urethroplasty using with long strip oral mucosal grafts. We also analyzed whether a lingual mucosa graft is a good substitute for repairing long segment urethral strictures. This retrospective study was done in 81 male patients with complex urethral strictures who underwent oral mucosal graft urethroplasty. Patients with long segment (8 cm or greater) anterior urethral strictures who were considered candidates for long strip lingual mucosa graft urethroplasty were included in study. Oral mucosal graft urethroplasty was performed in 81 patients with complex urethral strictures between August 2006 and December 2014. Mean urethral stricture length was 12.1 cm (range 8 to 20). A single 9 to 12 cm long strip lingual mucosa graft was used in 52 patients, a lingual mucosa graft greater than 12 cm was placed in 17 and a lingual mucosa graft combined with a buccal mucosal graft was used in 12. Mean followup was 41 months (range 15 to 86) postoperatively. The overall urethroplasty success rate was 82.7%. Urethral complications developed in 14 patients (17.3%), including urethral strictures in 10 and urethrocutaneous fistulas in 4. At 12 months 5 patients (6.2%) reported minimal difficulty with fine motor movement of the tongue. Lingual mucosa harvested from the ventrolateral surface of the tongue can provide a wide and long graft that is an excellent urethral substitute. Donor site complications are primarily limited to postoperative year 1. Our study confirms that the lingual mucosa graft is a good substitute for urethral reconstruction and lingual mucosa graft urethroplasty is a valuable procedure to treat long anterior urethral strictures.

Correction of Residual Ventral Penile Curvature After Division of the Urethral Plate in the First Stage of a 2-Stage Proximal Hypospadias Repair.

The first stage of a 2-stage proximal hypospadias repair involves division of the urethral plate and correction of any residual ventral penile curvature (VPC). Options to correct residual VPC include dorsal corporal shortening or ventral corporal lengthening techniques. This review discusses these options and suggests an approach to management. Recent reports of 2-stage proximal hypospadias repairs indicate low rates of recurrent VPC with either dorsal corporal shortening or ventral corporal lengthening. Dorsal corporal shortening with dorsal plication may be preferentially used for mild to moderate residual VPC after division of urethral plate and ventral corporal lengthening reserved for severe residual VPC. Ventral corporal lengthening with grafts has been associated with urethroplasty complications after the second stage hypospadias surgery. Ventral corporal lengthening with relaxing incisions of corpora has been reported, but concerns about adverse effects require longer term studies. Little guidance exists to choose the best technique for VPC correction during first stage hypospadias repair after division of urethral plate. Reported literature suggests good results with dorsal plication techniques and ventral corporal lengthening. A practical approach is to use dorsal plication techniques for mild to moderate residual VPC after division of urethral plate (<45°) and reserve ventral corporal lengthening for severe residual VPC (>45°).

Re-operative urethroplasty after failed hypospadias repair: how prior surgery impacts risk for additional complications

The primary aim of this report was to compare urethroplasty complications for primary distal and proximal repairs with those after 1, 2, 3, and 4 or more re-operations. Prospectively collected data on consecutive hypospadias repairs (tubularized incised plate (TIP), inlay, two-stage graft) from 2000 to 2015 were reviewed. Isolated fistula closures were excluded. Extracted information included patient age, meatal location, repair type, primary vs. re-operative surgery, number of prior operations, any testosterone use, glans width, and urethroplasty complications. Pre-operative testosterone stimulation was used during the study period until 2012. Initially, it was given for a subjectively small-appearing glans, but from 2008 to 2012 use was determined by glans width <14mm. Patients initially managed elsewhere were queried for any testosterone treatment. The number of prior operations was determined by patient history and confirmed by review of records. Calibrations, dilations, cystoscopies, and/or isolated skin revisions were not considered as prior urethroplasty operations. Multiple logistic regression was performed for all patients, and for the subset of patients undergoing re-operation, using stepwise regression for the following potential risk factors: meatal location (distal vs. midshaft/proximal), number of prior surgeries (0, 1, 2, 3, ≥4), pre-operative testosterone use (yes/no), small glans (<14 vs. ≥14), surgery type (TIP, inlay and two-stage graft), and age (continuous in months), with P-values <0.05 considered statistically significant. In contrast to the 135/1085 (12%) complication rate in patients undergoing primary distal and proximal TIP repair, re-operative urethroplasty complications occurred in 61/191 (32%) TIP, 16/46 (35%) inlay, and 49/124 (40%) two-stage repairs, P<0.0001. Data regarding testosterone use was available for 1490 (96%) patients. A total of 139 received therapy, of which 65 (46%) had urethroplasty complications vs. 229 of 1351 (16%) without treatment, P=0.0001. Logistic regression in 1536 patients demonstrated that each prior surgery increased the odds of subsequent urethroplasty complications 1.5-fold (OR 1.51, 95% CI 1.25-1.83), along with small glans <14mm (OR 2.40, 95% CI 1.48-3.87), mid/proximal meatal location (OR 2.54, 95% CI 1.65-3.92), and use of pre-operative testosterone (OR 2.57, 95% CI 1.53-4.31); age and surgery type did not increase odds (AUC=0.739). Urethroplasty complications doubled in people undergoing a second hypospadias urethroplasty compared with those undergoing primary repair. This risk increased to 40% with three or more re-operations. Logistic regression demonstrates that each surgery increases the odds for additional complications 1.5-fold. Mid/proximal meatal location, small glans <14mm, and use of pre-operative testosterone also significantly increase odds for complications. These observations support the theory that previously operated tissues have less robust vascularity than assumed in a primary repair, and suggest additional adjunctive therapies are needed to improve wound healing in re-operations. The finding that even a single re-operative urethroplasty has twice the risk for additional complications vs. a primary repair emphasizes the need for hypospadias surgeons to 'get it right the first time'. The fact that 40% of the re-operative urethroplasties in this series followed distal repairs emphasizes that there is no 'minor' hypospadias. A single re-operative hypospadias urethroplasty has twice the risk for additional complications vs. the primary repair, which increases to 40% with three or more re-operations. These results support a theory that vascularity of penile tissues decreases with successive operations, and suggest the need for treatments to improve vascularity. The higher risk for complications during re-operative urethroplasties also emphasizes the need to get the initial repair correct.

Preputial reconstruction in hypospadias repair

In principle, the prepuce can be reconstructed during hypospadias repair, but the procedure has not gained wide acceptance and preputial reconstruction (PR) is surrounded by several controversies. A review is provided of the technique for PR, how PR combines with the other steps of hypospadias repair, the risks of complications related to the urethroplasty and specific to PR, and the results of PR with particular regard to the relevance for the patient and his family. PR can be important for patients requiring hypospadias repair and their parents. It can be performed in almost all patients with distal hypospadias except perhaps those with the most asymmetrical prepuces or severe ventral skin deficiency. PR does not seem to increase urethroplasty complications, but combination of PR with tubularisation of the urethral plate urethroplasty seems to offer the best chance of success. Specific complications occur in around 8% of patients and include partial or complete dehiscence of the prepuce and secondary phimosis. To prevent the latter, the reconstructed prepuce should be easily retractile at the end of surgery. Technical modifications can help to achieve this goal. Cosmetically, reconstructed prepuces are not fully normal, but the abnormality could be less important for a patient and his parents that the complete absence of the prepuce. On the basis of the evidence summarised above, an algorithm for PR in patients with distal hypospadias is proposed. PR can be offered to the vast majority of distal hypospadias patients, although some modification of the technique for hypospadias repair can be required. Retractility of the reconstructed prepuce at the end of surgery seems paramount for final success.

Is glans penis width a risk factor for complications after hypospadias repair?

Recent studies have suggested that a smaller glans penis size may be associated with a higher likelihood of complications after hypospadias repair. Accurate identification of risk factors other than the well-understood variable of meatal location would allow development of better prognostic models and individualized risk stratification. To test the hypothesis that a smaller width of the glans penis predicts adverse outcomes after hypospadias surgery. Prospectively recorded clinical data were reviewed from a single-institution registry of primary hypospadias repairs performed between 2011 and 2014. Follow-up records were examined for occurrence of complications. Urethroplasty complications were defined to include meatal stenosis, dehiscence, urethrocutaneous fistula, urethral stricture, and/or urethral diverticulum. The subset of meatal stenosis and dehiscence were regarded as glanular complications. Regression analyses were performed to determine association between glans width and occurrence of complications. Because pre-operative androgen stimulation is known to increase glans penis size, separate subgroup analyses were included of patients with and without pre-operative use of testosterone cream. A total of 159 patients met criteria for inclusion in the study cohort: 140 patients underwent a single-stage repair, while 19 patients had a two-stage repair. The median glans penis width was 15mm (range 10-22). Eighty-four patients (53%) received testosterone cream pre-operatively and had a significantly wider glans penis than the 75 patients who did not (median 15.5 vs 14mm; P<0.001). Median clinical follow-up was 7 months (IQR 1-12), with a minimum time elapsed since surgery of 10months at the time of chart review. Twenty-four patients (15%) had one or more urethroplasty complications, including 11 (7%) with glanular complications. Overall, there was no statistically significant association between glans width and urethroplasty complications (P=0.26) or glanular complications (P=0.90) (Summary Table). Subgroup analyses of patients with and without pre-operative testosterone also revealed no significant associations between glans width and complications. Glans penis width was not a risk factor for complications after hypospadias repair. This finding differs from the results of other recent studies and encourages further research into the value of measuring penile parameters in patients undergoing hypospadias repair.

The success of tubularized-incised plate urethroplasty in adults and children.

PurposeHypospadias repair is rarely performed in adults. It is believed that the success rate is lower in adulthood. We aimed to compare the success rate of primary hypospadias repair with tubularized-incised plate (TIP) urethroplasty in adults and children.Patients and methodsThe databases of consecutive boys and adults who were treated with TIP urethroplasty for primary hypospadias between 2012 and 2015 were evaluated. All operations in the boys and adult patients were performed by a single surgeon. We considered urethroplasty complications to include a urethrocutaneous fistula, neourethral stricture, meatal stenosis, diverticulum, and glans dehiscence. Urine flow was also evaluated using uroflowmetry.ResultsSeventy-seven consecutive patients underwent surgery by a single surgeon in the last 3 years for hypospadias repair. Nineteen of these patients were adults. Urethrocutaneous fistulae developed in 2 of the 19 (10.5 %) adults, and 3 of the 58 (5.2 %) boys. In addition, there were urinary tract infections in 2 (3.4 %) children, meatal stenosis in 1 (1.7 %) child, and glans dehiscence in 1 (5.3 %) adult. Uroflowmetry was normal in all patients. There was no difference in outcomes between boys and adults.ConclusionOur data showed that the success rate of hypospadias repair with TIP urethroplasty is similar in adults and children. TIP urethroplasty is associated with good results in adults and boys.

Does Preputial Reconstruction Increase Complication Rate of Hypospadias Repair? 20-Year Systematic Review and Meta-Analysis.

We performed a systematic review of the literature on preputial reconstruction (PR) during hypospadias repair to determine the cumulative risk of preputial skin complications and the influence of PR on urethroplasty complications, namely, fistula formation and overall reoperation rate of the repair. A systematic search of the literature published after 06/1995 was performed in 06/2015 using the keyword "hypospadias." Only studies on the outcome of PR in children, defined as dehiscence of the reconstructed prepuce or secondary phimosis needing circumcision, were selected. A meta-analysis of studies comparing PR vs. circumcision was performed for the outcomes "hypospadias fistula formation" and "reoperation rate." Twenty studies were identified. Nineteen reported the outcome of PR in 2115 patients. Overall, 95% (2016/2115) of patients undergoing PR had distal hypospadias. The cumulative rate of PR complications was 7.7% (163/2115 patients), including 5.7% (121/2115 patients) preputial dehiscences and 1.5% (35/2117 reported patients) secondary phimoses needing circumcision. A meta-analysis of seven studies comparing patients undergoing PR vs. circumcision showed no increased risk of urethral fistula formation associated with PR, odds ratio (OR) (Mantel-Haenszel, Fixed effect, 95% CI), 1.25 (0.80-1.97). Likewise, two studies comparing the overall reoperation rate did not show an increased risk of reoperation associated with PR, OR (Mantel-Haenszel, Random effect, 95% CI), 1.27 (0.45-3.58). PR carries an 8% risk of specific complications (dehiscence of reconstructed prepuce or secondary phimosis needing circumcision), but does not seem to increase the risk of urethroplasty complications, and the overall reoperation rate of hypospadias repair.

Results of distal hypospadias repair after pediatric urology fellowship training: A comparison of junior surgeons with their mentor

Teaching and learning hypospadias repair is a major component of pediatric urology fellowship training. Educators must transfer skills to fellows, without increasing patient complications. Nevertheless, few studies report results of surgeons during their first years of independent practice. To review outcomes of distal hypospadias repairs performed during the same 2-year period by consecutive, recently matriculated, surgeons in independent practice, and to compare them to results by their mentor (with >20 years of experience). Exposure to hypospadias surgery during fellowship was determined from case logs of five consecutive fellows completing training from 2007-2011. TIP was the only technique used to repair distal hypospadias. No fellow operated independently or performed complete repairs under supervision. Instead, the first 3 months were spent assisting their mentor, observing surgical methodology and decision-making. Then, each performed selected portions under direct supervision, including: degloving, penile straightening, developing glans wings, incising and tubularizing the urethral plate, creating a barrier layer, sewing the glansplasty, and skin closure. Overall fellow participation in each case was <50%. In 2011-2012, urethroplasty complications (fistula, glans dehiscence, meatal stenosis, urethral stricture, diverticulum) were recorded for consecutive patients undergoing primary distal repair by these recent graduates in their independent practices. The fellow graduating in 2011 provided 1 year of data. All patients undergoing repair during the study period were included in the analysis, except those lost to follow-up after catheter removal. Composite urethroplasty complications were compared between junior surgeons, and between junior surgeons and their mentor, with Fisher's exact contingency test. Training logs indicated fellow participation ranged from 76-134 hypospadias repairs, including distal, proximal and reoperative surgeries. Post-graduation case volumes ranged from 25-68 by junior surgeons versus 136 by the mentor. With similar mean follow-up, urethroplasty complication rates were statistically the same between the former fellows, and between them versus the mentor,ranging from 5-13%. Nearly all were fistulas or glans dehiscence. Junior surgeons reported they performed TIP as learned during fellowship, with one exception who used 7-0 polydioxanone rather than polyglactin for urethroplasty. This is the first study directly comparing hypospadias surgical outcomes by recently graduated fellows in independent practice with those of their mentor. We found junior surgeons achieved similar results for distal TIP hypospadias repair. Although their participation during training largely comprised observation and surgical assistance, with discrete performance of key steps, skills sufficient toduplicate the mentor's results were transferred. These data suggest there should be no learning curve for distal hypospadias after training. This report raises several considerations for surgical educators. First, mentors should review their own results, to be certain that they are correctly performing and teaching procedures. Second, programs need to determine key steps for procedures they teach, and then emphasize their optimal performance. Finally, mentors should expect former fellows to report back their initial results of hypospadias repair to be certain lessons taught were learned. Otherwise, preventable complications resulting from technical errors will be multiplied in the children operated by their trainees as they enter independent practice.

Glans size is an independent risk factor for urethroplasty complications after hypospadias repair

We hypothesized small glans size could increase urethroplasty complications (UC) following hypospadias repair. To test this, we measured glans width at its widest point in consecutive patients with hypospadias, and following a protocol for surgical decision-making, we then assessed post-operative UC using pre-determined definitions. We now report analysis of glans size as a potential additional independent risk factor for UC after hypospadias repair. Consecutive prepubertal patients undergoing hypospadias repair (2009-2013) had maximum glans width measured using calipers (Fig. 1). There were no differences in surgical technique for urethroplasty or glansplasty in this series based on the measured size of the glans. Multivariate logistic regression analyzed UC (fistula, glans dehiscence, diverticulum, stricture and/or meatal stenosis) based on glans size while adjusting for patient age, meatus (distal or midshaft/proximal), type of repair (TIP, inlay, 2-stage), surgeon, and primary or reoperative repair. Glans size was analyzed as both a continuous and dichotomous variable, with small glans defined as <14mm. Mean glans size was 15mm (10-27mm) in 490 boys (mean 1.5 years) undergoing 432 primary repairs (380d/19mid/33prox), and 58 reoperations (28d/7mid/23prox). Increasing age between 3 months and 10 years did not correlate with increasing glans size (R=0.01, p=0.18). 17% had small glans <14mm. UC occurred in 61 (13%) primary TIP, 2-stage, and reoperative repairs, including 20/81 (25%) patients with small glans <14mm, versus 41/409 (10%) in patients with glans width ≥14mm (p=0.0003). On multivariate analysis, small glans size (OR 3.5, 95% CI 1.8-6.8), reoperations (OR 3.0, 95% CI 1.4-6.5) and mid/proximal meatus (OR 3.1, 95% CI 1.6-6.2) were independent risk factors for UC. Surgeon, repair type, and patient age did not impact risk for UC. Analysis with glans size as a continuous variable demonstrated each 1mm increase in size decreased odds of UC (OR 0.8, 95% CI 0.7-0.9). Our analysis of prospectively-collected data from a standardized management protocol in 490 consecutive boys undergoing hypospadias repair adds small glans size, defined as width <14mm, to proximal meatal location and reoperation as an independent risk factor for UC. Best means to modify this factor remain to be determined. Our data suggest that others analyzing potential risks for hypospadias UC should similarly measure and report glans width.

Repeat endoscopic procedures, however, do not typically offer cure and may increase stricture complexity, threatening urethroplasty outcomes. Our objective was to evaluate the association between the number of endoscopic procedures with stricture length, urethroplasty complexity and urethroplasty outcomes. METHODS A retrospective review of 840 consecutive urethral reconstructions performed by a single surgeon between August 2003 and May 2014 was completed. Exclusion criteria were prior urethroplasty, penile or panurethral strictures, posterior stenosis, staged repair or incomplete datasets. Number of endoscopic treatments were analysed as an ordinal variable by dividing the number of endoscopic treatments into 4 groups (group 1 = 0 treatments, group 2= 1-2, group 3 = 3-5, group 4 = greater than 5) and as a continuous variable. Preoperative patient demographics and postoperative outcomes were first compared using univariate binary regression, followed by multivariate binary regression. Outcomes measures were stricture length (measured intra-operatively), complexity of urethroplasty (either an anastomotic technique or a more complex tissue substitution), urethroplasty success (defined as the easy passage of a 16Fr cystoscope), and Clavien complications. RESULTS Of the 430 patients with bulbar urethral strictures eligible for analysis, 49 were in group 1, 182 were group 2, 141 in group 3, and 58 were group 4. Using linear regression as both an ordinal and continuous variable, an increase in the number of endoscopic manipulations was strongly associated with increased stricture length (p<0.001 and p=0.01) and urethroplasty complexity (p<0.001 and p=0.02). Using multivariate binary regression, no association of urethroplasty success or complications were found with number of endoscopic treatments (p=0.85 and p=0.56, respectively). Urethroplasty failed in 2% of group 0 (1/50), 6.6% of group 1 (12/182), 9.0% of group 3 (13/143), and 8.6% of group 4 (5/65). CONCLUSIONS Temporizing patients with repeat endoscopic procedures is associated with increasing stricture length and urethroplasty complexity. Despite this, no association was found between the rate of stricture recurrence or accompanying urethroplasty complications. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 193Issue 4SApril 2015Page: e320 Advertisement Copyright & Permissions© 2015 by American Urological Association Education and Research, Inc.MetricsAuthor Information David W.

Trends, Utilization, and Immediate Perioperative Complications of Urethroplasty in the United States: Data From the National Inpatient Sample 2000-2010

To determine national urethroplasty trends based on type of surgery and patient and hospital characteristics. We hypothesized that the number of complex urethroplasty procedures performed has increased over time and may be associated with increased periprocedure complications. The National Inpatient Sample from years 2000 to 2010 was queried for patients with urethroplasty-associated International Classification of Diseases, Ninth Revision, Clinical Modification codes. We analyzed trends in urethroplasty procedures, patient demographics, comorbidities, and hospital characteristics. We evaluated the relationship between patient demographics and comorbid disease, length of hospital stay, hospital charges, and inpatient complications. During the study period, an estimated 13,700 men (95% confidence interval, 9507-17,894) underwent urethroplasty nationally. Excision with primary anastomosis, buccal graft, and other graft or flap urethroplasty comprised 80.3%, 14.3%, and 5.4%, respectively. Buccal mucosa graft procedures increased over time (P = .03). Only 1.6% of hospitals have ≥ 20 urethroplasties performed annually. Urethroplasty type and urethroplasty volume were not associated with immediate complication rates. Hypertension, diabetes, chronic pulmonary disease, and obesity were the most common comorbidities in urethroplasty patients. Complications during urethroplasty hospitalization occurred in 6.6% of men, with surgical or wound complications being the most common (5.2%). Postoperative mortality was exceedingly rare. Older patients, African Americans, and patients with increased comorbidities were more likely to have complications. An increasing number of buccal mucosa graft urethroplasties occurred over time. Urethroplasty patients have low immediate perioperative morbidity (6.6%) and mortality (0.07%). Patients who are older, African American, or have more comorbid conditions have greater risk for complications.

Recent advances in understanding/management of hypospadias.

Hypospadias is the second most common birth anomaly, affecting 1 of every 300 males. The abnormal position of the urinary opening, and associated downward curvature of the penis in some cases, potentially impact both urinary and sexual function. Modern surgical correction most often involves tubularization of the urethral plate, those tissues which normally should have completed urethral development.This article discusses recent progress in hypospadias repair. Prospective data collection in consecutive patients promotes better understanding of both patient and technical factors that influence surgical complications. Patients with a proximal urinary opening near or within the scrotum, those failing prior to repairs, and/or those with a small glans diameter have increased likelihood for urethroplasty complications. Quality review of reliable data led to two layer urethroplasty covered with tunica vaginalis in proximal repairs, significantly reducing postoperative fistulas. Neither preoperative androgens used to grow a small diameter glans, nor a change in sutures used to approximate the glans wings reduced wound dehiscence, but a recent technical modification of the glansplasty with more extensive dissection before suturing has. The observation that reoperation increases risk for further complications three-fold suggests the less common proximal repairs and reoperations should be subspecialized so that designated surgeons can gain greater expertise.In addition, surgeons performing hypospadias repair must better define the complications that occur so that scientific reporting of outcomes becomes more standardized. Standardized objective means to assess results are also needed so that surgeons performing different repairs can compare outcomes.

Revision Urethroplasty Success Is Comparable to Primary Urethroplasty: A Comparative Analysis

To assess the efficacy and complications of revision urethroplasty compared with urethroplasty-naïve controls. A retrospective analysis was performed of 534 urethroplasties performed by a single surgeon from August 2003 to March 2011. Patient age, stricture length, location, etiology, comorbidities, and type of surgery were recorded. Statistical comparison between the revision cohort and urethroplasty-naïve group were made using Fisher, χ(2), and unpaired t tests, with significance at P < .05 (2-tailed). The primary outcome was urethral patency assessed by cystoscopy. Secondary (subjective) outcome measures included erectile dysfunction, pain, urinary tract infection, or chordee at 6 months. A total of 476 patients met inclusion criteria with completed cystoscopic follow-up. Previous urethroplasty had failed in 49 patients (10.3%). Patients undergoing revision urethroplasty were more likely to have stricture in the penile urethra (22.4%; P = .001), to have strictures exceeding 4 cm in length (71.4% vs 54.3%; P = .023), and to require tissue transfer (83.6% vs 65.1%; P = .010). Urethral patency rates did not differ significantly between naïve and revision urethroplasty cohorts, with a mean follow-up of 49.9 months (94.6% vs 91.8%; P = .518). The revision group had a higher incidence of chordee (2.7% vs 14.3%; P = .001) and urinary tract infection (3.5% vs 10.2%; P = .04). The rates of erectile dysfunction, scrotal pain, lower urinary tract symptoms, and incontinence did not differ significantly between the 2 groups. Revision urethroplasty is an effective treatment option for recurrent stricture after urethroplasty and is comparable to results in urethroplasty-naïve patients. Patients undergoing revision urethroplasty are more likely to require tissue transfer and experience higher rates of chordee and urinary tract infection.

Primary and Reoperative Hypospadias Repair in Adults—Are Results Different than in Children?

There is widespread belief that hypospadias surgery in adults has a greaterurethroplasty complication rate than similar repair in children. We compared outcomes of primary and reoperative hypospadias repair in adults vs children. We evaluated prospectively maintained databases of consecutive boys and adults, defined as Tanner 4 or greater, treated with primary or reoperative hypospadias repair from 2000 to 2013. We searched for urethroplasty complications, including fistula, glans dehiscence, stricture/stenosis and diverticulum. All operations were done with the goal of creating a neomeatus at the normal location at the tip of the glans. Univariate and multivariate analyses were done to determine whether pubertal status impacted urethroplasty complications. A total of 1,140 patients were operated on by a single surgeon, including 69 adults with a mean age of 23 years. Complications developed in 209 cases (18%), including 124 of 883 primary repairs (14%) and 85 of 257 reoperations (33%). There was no difference in outcomes between adults and children. Complications were noted in 1 of 8 men (12.5%) vs 123 of 871 children (14%) with primary repair (p = 0.9) and in 16 of 61 (26%) vs 69 of 196 (35%) with reoperation (p = 0.2). Multivariate analysis showed that a proximal meatus and reoperation were risk factors for complications but not pubertal status. In contrast to popular belief, our data do not indicate a greater risk for urethroplasty complications after hypospadias surgery performed in adulthood. Repair in adults can be done using the same techniques as in children with the same goal of a neomeatus at the tip of the glans.

Clinical application and single factor analysis of onlay island flap urethroplasty

Objective To investigate the indications and complications of onlay island flap urethroplasty in hypospadias. Methods Retrospective analysis 51 cases who received the onlay urethroplasty from Mar.2005 to Sep.2012 at the First Affiliated Hospital of Guangxi Medical University.Their ages were from 2 years to 12 years, the median age was 4 years and 3 months.Forty-three cases received the operation for the first time, 8 cases were re-operation.The prepuce island flaps were implemented in all cases.Factors which contributed to the successful operation ratio were compared, such as the levels of penile curvature, the lengths of urethral defects, first operation or reoperation, the size of glans. Results The operation achievement ratio was 82.4%(42/51 cases). There were 7 cases urethrocutaneous fistula(6 cases were then cured by reoperation, 1 case healed naturally). One case had urinary meatus had retraction.There was another case with persisting penile curvature.Some differences in factors had no statistical significance, such as the levels of penile curvature, the lengths of urethral defects, first operation or reoperation(χ2=0.249, 0.287, 1.208; all P>0.05). The difference in glans size had statistical significance(χ2=3.393, P<0.05). Conclusions Onlay urethroplasty was suitable for the cases of coronary sulcus of penis and extremitas anterior penis, but for proximal cases, this therapy must be applied very carefully because of persisting penile curvature.For some reconstruction cases, Onlay urethroplasty was suitable, but the island flap must be designed flexibly.Urethrocutaneous fistula was the most complication, especially in some small flat glans.

Preputioplasty associated with urethroplasty for correction of distal hypospadias: A prospective study and proposition of a new objective scoring system for evaluation of esthetic and functional outcome

ObjectiveMost surgical procedures for correction of hypospadias involve the removal of foreskin resulting in a circumcised penis. We report our experience and the medium-term results in the reconstruction of the foreskin during the correction of distal hypospadias. Materials and methodsBetween January 2007 and December 2011, 445 patients aged between 8 and 120 months underwent surgical correction of hypospadias. In 354 out of 445 patients, we performed the reconstruction of the foreskin. Urethroplasty was performed according to either the TIPU (tubularized incised urethral plate urethroplasty; Snodgrass) technique (233/354, 66%) or MAGPI (meatal advancement glanduloplasty incorporated) procedure (121/354, 34%). In 91 out of 445 patients urethroplasty was performed using classic TIPU technique and they were circumcised. The cosmetic and functional results were evaluated using the Hypospadias Objective Penile Evaluation (HOPE) scoring system. ResultsAt a 12 months follow-up, 300 patients (84.7%) had retractable foreskin while 54 patients (15.3%) required postoperative steroid application. We had a total complication rate of 8.7%. As for preputioplasty, 16 patients (4.5%) had partial or total dehiscence of the reconstructed foreskin, one patient was circumcised for persistent phimosis (0.2%). As for urethroplasty complications, we recorded 11 fistulas (3.1%) and three stenosis (0.9%). The complication rate of the control group of circumcised patients was of 3.3% (2 fistulas [2.1%] and 1 stenosis [1.2%]). ConclusionsOur experience shows that foreskin reconstruction can be performed successfully in selected patients with distal hypospadias. However, preputioplasty add an additional 4.7% complication rate. As for the complications of urethroplasty, it seems that preputioplasty does not increase the incidence of complications on the urethra reconstruction. We propose a new objective scoring system (modified HOPE score) for evaluation of esthetic and functional outcome.
