ABSTRACT Background: Today, tubularized incised plate (TIP) urethroplasty is the most commonly performed operation for distal and mid-penile hypospadias. Reports from different centers worldwide confirm its nearly universal applicability and low complications rate. Aim: Evaluation of the urethral plate characters and its effect on the outcome of TIP urethroplasty. Materials and Methods: Between 2010 and 2013, 100 children with primary distal penile hypospadias underwent TIP urethroplasty. Urethral plates were categorized as flat, cleft, and deeply grooved. Postoperatively, patients were followed-up for evaluation of meatal stenosis, fistula formation, and glandular dehiscence at 1 st , 3 rd and 6 th months. Patients were followed-up for urethral calibration by urethral sound 8 Fr at 3 rd and 6 months follow-up. Data were statistically analysed using Epi info program to correlate between the width, plate shape, and complications. Results: Mean age at surgery was 4.3 years. Patients were followed-up for an average period of 6.4 months. Pre-operative location of the meatus was reported as coronal in 46, subcoronal in 50 and anterior penile in 4 cases. Urethral plate characters were flat in 26 cases, cleft in 52, and deeply grooved in 22. Urethral plate width was >8 mm in 74 cases and <8 mm in 26. Patients with urethral plate <8 mm had a statistically significant higher fistula rate (P = 0.004) and failed 8 Fr calibrations in 26.9% (P = 0.01) compared with the patients with urethral plate >8 mm. In addition, we also founds higher fistula rate and failed 8 Fr calibrations in flat urethral plate. Conclusions: An adequate urethral plate width (>8 mm) is essential for successful TIP repair. Lower success rates with flat plates may need buccal mucosal augmentation to improve the results.

BackgroundTubularized incised plate urethroplasty is the most common hypospadias repair technique. However, there are unanswered questions and debates about the anatomical prognostic factors affecting the repair outcomes. This study tried to address some of the problems in the studies compromising the results of the current body of literature.MethodsA prospective cohort of 101 males aged 1–3 years undergoing primary distal to mid-shaft hypospadias repair were enrolled in the study. Complications including edema, erection, inadvertent removal of the urethral stent, surgical wound infection, bladder spasm, hematoma, and hemorrhage were evaluated. Studies in the current literature were reviewed to achieve a better perspective for future investigations.ResultsPersistent complications were found in 16 cases (15.8%) including fistula formation, the persistence of chordee, meatal stenosis, glans, and urethral dehiscence. The mean follow-up time was 6.6±3.4 months. In the single-variable analysis, the meatal location, the length and width of the urethral plate, and the reversible acute postoperative events were significantly associated with the complications. Furthermore, fistula formation was associated with acute surgical site infection (p<0.001). However, the multivariable regression study revealed the presurgical meatal location to be the only statistically significant factor (p=0.03). Notably, the glans diameter or glanular groove shape, urethral plate dimensions, or presence of mild chordee were not independently associated with the outcomes (p>0.05).ConclusionsOur study on the toddlers with hypospadias surgery revealed that the location of urethral meatal was the main predicting factor in the development of major complications. Furthermore, the fistula formation at the infected surgical site emphasizes the importance of postsurgical care.

Abstract Objective:To determine the cosmetic and functional outcomes of hypospadias repair in relation to the width of the urethral plate in addition to granular width and configuration.Materials and methodsThe study was a prospective evaluation of patients operated for hypospadias after approval of ethical committee a formal consent were taken from parents. The urethral plate width (UPW) and glans width (GW) of the patients were measured preoperatively using standard calipers. The width of the urethral plate was correlated to the cosmetic outcome (using hypospadias objective penile evaluation [HOPE]) and functional outcome (using the urinary stream) of hypospadias repair.All patients were managed via the same technique using Snodgrass tubularized incised plate repair (TIP). All operations were performed by a single surgeon. All intaoperative data were recorded. All patients were followed up for 1 year. Success was defined as slit shaped meatus at the tip of the glans with no stenosis, fistula or diverticulum.Results:All 38 patients were evaluated at 6 months and 1 year follow up. The mean age at surgery was 4.5 ± 2.1 years. Overall, the mean ± SD of UPW was 10.92 ± 1.24 mm. a 24 patients (61.5 %) (Group A) had a urethral plate width of less than 8 mm while 14 patients (35.9 %) (group B) had a urethral plate width greater or equal to 8 mm. the mean ± SD of GW was 9.52 ± 1.56 mm. Success was documented in 36/38 patients (94.3%).The only complication was Fistula in two patient (6.7 %), glans dehiscensce in three patients (10%). Success rate was not statistically different in correlation of UPW and GW (p=0.5).The only statistically significant difference between all patients was a longer operative time in the patients with deficient urethral plate compared to others with adequate urethral plate (p= 0.005). The urinary stream was straight in 32 boys and sprayed in 6. Overall, mean ± SD HOPE score was 39.1 ± 8.83. A significant correlation found between the cosmetic outcome of the two groups and HOPE score (p = 0.06).Conclusions:The pre-incision urethral plate width and glanular width was not correlated with the TIP outcome. A better HOPE score is associated with wide urethral plate.

The Impact

SummaryBackgroundTubularized incised plate (TIP) urethroplasty as the most common hypospadias repair method, aims to achieve normal functioning of the penis along with cosmetic reconstruction. However, there are remaining questions toward anatomical prognostic factors affecting the results of surgery. Lack of age-matched controls or controlling for meatal location, employment of several surgical techniques or multiple surgeons, or age heterogeneity of the study population are the problems affected the results of the current body of literature.ObjectiveThis prospective study aimed to evaluate the preoperative factors to predict future complications associated with hypospadias repair outcomes in males aged between 1-3 years and performed by a single surgeon with employing multivariable analysis.Patients and methodsA prospective cohort of 101 males aging from 1 to 3 years with distal to mid-shaft hypospadias were consecutively selected for TIP repair. The urethral plate dimensions in erect and flaccid states, penile length, glans diameter, and chordee were evaluated individually before reconstruction. After surgery and during follow-up visits, the subsequent transient and persistent complications were recorded.ResultsPostoperatively, the acute transient events were observed in 42 cases (41.6%) and the persistent complications in 16 cases (15.8%). The uncomplicated group had a higher percentage of patients with distal meatal location than the complicated group (P=0.01%). Furthermore, fistula formation was notably higher in the group with acute surgical site infection (P<0.001). wedThe analysis also shothe width of the urethral plate to be associated with the development of complications (P=0.03).ConclusionBy performing TIP by a single surgeon on a homogenous study population and eliminating the impact of severe chordee as a potential cofounding variable, this study prospectively found that out of the anatomical specifications, pre- and postoperative factors, the urethral meatus location was the only significant and independent predictor of the development of complications in young children with midshaft to distal hypospadias. Moreover we found that in young children the wider the plate was, the more complications happened. Consequently, we hypostatized that in young children who their anatomical dimensions are almost in same range of values, a combination of urethral width and depth should be considered in the investigation of prognostic factors for hypospadias repair outcomes.

The mean age at surgery was 4.5 ± 2.1 years. We categorized the patients into two groups:- (Group A) had a urethral plate width of less than 8 mm, they were 24 patients (63.15 %). (Group B) had a urethral plate width greater or equal to 8 mm. (group B) had a urethral plate width greater or equal to 8 mm, they are 14 patients (36.8 %) Overall, the mean ± of UPW was 10.92 ± 1.24 mm while the mean ± SD of GW was 9.52 ± 1.56 mm. Success was documented in 36/38 patients (94.7%). The documented complication was Fistula in two patient (5.2 %), glans dehiscensce in three patients (7.9%). Success rate was not statistically different in correlation of UPW and GW (p=0.5). The urinary stream was straight in 32 boys and sprayed in 6. Overall, mean ± SD HOPE score was 39.1 ± 8.83.

A significant correlation found between the cosmetic outcome of the two groups and HOPE score (p = 0.06). Conclusions: The pre-incision urethral plate width and glanular width was not correlated with the TIP outcome. A better HOPE score is associated with wide urethral plate.
