Reoperative Hypospadias Repair Based on Urethral Plate Status (original) (raw)

Comprehensive analysis of tubularized incised-plate urethroplasty in primary and re-operative hypospadias

BJU International, 2004

To retrospectively review our experience of the tubularized incised-plate (TIP) urethroplasty over the last 4 years. From 1998 to December 2001, 133 patients (mean age 7 years, sd 4, range 1-22), had a TIP urethroplasty by one surgeon for primary (103) and re-operative (30) hypospadias; the defects included 106 (79%) distal and mid-shaft, and 27 (21%) posterior shaft. The neourethra was covered by a subcutaneous flap in 66 (50%) patients or by corpus spongiosa (spongioplasty) in 31 (23%), with no cover in the remaining 36 (27%). In the last 20 patients (15%) a modified meatoplasty was used; the site and size of the new meatus was predetermined on the glans around a suitable catheter before any incision. Urethral stents were not used after repair in 39 (29%) patients, and regular meatal dilation was used only in patients with voiding difficulty and obvious tendency to stenosis. The presence of complications requiring re-operation and overall general appearance were recorded. The mean (sd) follow-up was 10 (5) months; there were 24 complications in 20 patients (15%), including a small fistula in 12 (9%), complete disruption of the repair in 4 (3%), meatal stenosis in seven (5%) and neourethral stricture in one (0.8%). Complications were not significantly different between primary and re-operative cases, and unaffected by the use of the stents. On univariate analysis complications were significantly higher with running than interrupted sutures, in repairs in the first 2 years of the study, in patients with posterior hypospadias, and in those with no neourethral coverage. However, the last two factors were the only significant independent risk factors in a multivariate analysis. Regular urethral dilatation was indicated in 43 patients (32%). Modified meatoplasty was associated with a significantly lower requirement for regular dilatation (P < 0.05) and no meatal stenosis. In the 113 complication-free patients the operation gave an excellent cosmetic appearance with a vertical slit meatus on the tip of conical glans in 110 (97%); there was slight meatal retraction in the remaining three patients. The TIP repair is a reliable method for treating both distal and proximal penile shaft hypospadias, is suitable for both primary and re-operative cases, and is more versatile than other repairs. Covering the neourethra with a flap or spongioplasty significantly improves the results. Regular urethral dilatation is required in a third of patients but modified meatoplasty obviates the need for regular dilatation and eliminates the risk of meatal stenosis.

Comprehensive Analysis of Six Years Experience in Tubularised Incised Plate Urethroplasty and its Extended Application in Primary and Secondary Hypospadias Repair

European Urology, 2003

Objective: We evaluated the potential of tubularised incised plate (TIP) urethroplasty in primary and secondary hypospadias repair focusing on the extended application of this procedure, the utility and handling of the urethral plate and operative results. Methods: In this retrospective study, we analysed the medical records of 228 children with different levels of the hypospadiac meatus who underwent a TIP procedure between February 1997 and December 2002. The children were followed a mean of 42 months. Our medical records provided us with details about the location of the hypospadiac meatus, the width of the urethral plate before and after midline incision, primary versus secondary surgery, complications as well as notes on the extended application of the TIP procedure. Results: The overall postoperative complication rate was 7.8%. The overall fistula rate was 5.7%, with 4.1% in primary distal, 9.6% in primary proximal and 7.5% in secondary repair respectively. We had one case of meatal stenosis (0.4%) and one of urethral stricture (0.4%) and 3 cases of glandular dehiscence (1.3%). Due to the encouraging results, the frequency of TIP procedure in hypospadias surgery increased from 33% in 1997 to 82% in 2002. Conclusion: In our study the TIP procedure has emerged as the first-choice technique in primary hypospadias repair-irrespective of the level of the hypospadiac meatus and the width of the original urethral plate. This procedure has also proved to be favourable for many cases at secondary surgery. #

Retrospective analysis of the results obtained by using Mathieu and TIP urethroplasty techniques in recurrent hypospadias repairs

Journal of Pediatric Urology, 2008

To determine the effect of Mathieu and tubularized incised plate (TIP) urethroplasty techniques on the outcome of repair in recurrent hypospadias. Material and methods: A total of 78 patients who had undergone surgical correction by either Mathieu or TIP urethroplasty after unsuccessful hypospadias surgery were enrolled in this study. Cases were divided into two groups according to the operation technique performed. Surgical success rate of the techniques and the prognostic significance of age, type of diversion used, caliber and length of new urethra, and the number of previous operations were analyzed statistically. Results: Mathieu and TIP urethroplasties were performed in 57 and 21 patients, respectively. No statistically significant relation was found between the groups for age, length of new urethra created, caliber of the urethra, urinary diversion used, mean operation success rates and number of previous operations. From within-group analysis, Mathieu urethroplasty was found to have a statistically significant relationship with the number of previous operations (P Z 0.025, ManneWhitney U-test). Conclusions: Age, length and caliber of new urethra, and diversion type used seem to have no effect on the success rate of Mathieu and TIP urethroplasty in recurrent hypospadias restoration. The success of the Mathieu operation diminished proportionally to the number of previous failed surgeries.

Tubularized incised plate urethroplasty for distal and midpenile hypospadias reoperation: A single institute experience

Journal of Clinical Urology, 2017

Our study aimed to evaluate our experience in tubularized incised plate urethroplasty in distal and midpenile hypospadias reoperation. Patients and methods: This was a retrospective study in which we reviewed the medical records of 56 patients who underwent tubularized incised plate urethroplasty in distal and midpenile hypospadias reoperation. Tubularized incised plate urethroplasty was performed using a surgical technique like the primary tubularized incised plate repair based on the Snodgrass's method. We recorded complications and functional outcomes of redo procedures. Results: We reviewed 56 patients who ranged in age from 2-16 years (mean 7.02±3.8 years). The overall complication rate was 33.9% (n=19). Eight patients (14.3%) had fistula, six had meatal stenosis (10.7%), four had dehiscence (7.1%), and one had neourethral stenosis (1.8%). The complications occurred in 13 of mid-penile cases representing 50% of mid-penile cases but occurred in six cases of distal-penile cases (20%). The success rate of tubularized incised plate urethroplasty reoperation was 94.6% after repair of fistula and meatal stenosis by simple closure of fistula and meatoplasty. Conclusion: Tubularized incised plate urethroplasty is a safe and effective alternative procedure for hypospadias reoperations. The outcome is favorable if the urethral plate has no scars and with distal meatal location. The complication rate increases if the third redo is done and with midpenile meatal location.

Tubularized incised plate urethroplasty repair in adult hypospadias patients. Are results similar to those reported in the pediatric age group? A prospective study

African Journal of Urology

Abstract Objective Most studies published in the literature report on the results of tubularized incised plate urethroplasty (TIPU) for hypospadias repair in children. Hence, the objective of this study was to evaluate the results of TIPU repair in adults. Patients and methods The records of 60 adult patients with primary hypospadias treated with TIPU between April 2009 and May 2012 were reviewed. All the procedures were done by the same surgeon under similar conditions and using the same kind of instruments and suture material. On clinical examination, the meatal location, as well as the presence/absence of chordee and penile torsion was assessed. The quality of the spongiosum and the width of the urethral plate were evaluated intraoperatively. The postoperative complications and results were recorded and the data were analyzed. Results The patients’ age ranged from 16 to 27 years with a mean of 21 years. Out of the 60 cases, 43 (72%) had distal penile, 7 (11%) mid-penile and 10 (17%) proximal hypospadias. Penile torsion was present in 10 (17%) cases with 80% having a torsion ≤45° and 20% having a torsion of 45–90°. Ventral chordee ranging from 30° to 90° was present in 14 (23%) cases. Chordee correction was possible by penile de-gloving in 4 (29%) patients (2 with distal and 2 with mid-penile hypospadias), by further mobilization of the urethral plate with the corpus spongiosum in 3 (21%) and by proximal urethral mobilization in another 6 (42%) patients with proximal hypospadias. One (7%) patient also required tunica albuginea plication. The urethral plate was wide in 22 (37%), average in 26 (43%) and narrow in 12 (20%) patients. Fifty percent of the patients with a narrow urethral plate developed complications, compared to 15% of the patients whose urethral plate had an average width and none of the patients with a wide urethral plate. The spongiosum was well developed in 38 (63%) patients, while in 11 (18%) patients each the spongiosum was moderately and poorly developed. The complication rates were significantly higher (55%) in patients with a poorly developed spongiosum as compared to those with a well-developed spongiosum. The overall complication rate was 17% including fistula in 10% of the patients (2 patients with mid-penile and 4 patients with proximal hypospadias). Meatal stenosis was found in 4 patients with distal hypospadias (7%) who responded well to meatal dilatation. The fistula cases required surgical repair with a success rate of 100%. Mean hospitalization and follow-up were 9 days and 6–24 (median 37) months, respectively. Conclusions Complications encountered in the present study were urethral fistula and meatal stenosis with a higher incidence in patients with proximal hypospadias than reported in the literature. The important factors for the outcome of TIPU were the severity of hypospadias, the degree of curvature and the development of the spongiosum and urethral plate. Proximal hypospadias with a poor urethral plate and severe curvature in adults is not suitable for TIPU. In such cases, single-stage flap urethroplasty or two-stage buccal mucosal urethroplasty should be considered instead.

Which type of urethroplasty in failed hypospadias repair? An 8-year follow up

Journal of Pediatric Urology, 2013

To report our 8-year follow up for redo hypospadias repair. Methods: A total of 56 patients with previous failed hypospadias repair were included in our study. Patients' data were analyzed regarding age, number of previous repairs, meatal location, procedure performed, operative time and complications. Patients were followed up for 3 to 102 (mean 52) months. Results: Patient age ranged from 15 to 204 (mean 90.7) months. Forty-two patients had a single previous hypospadias repair, eleven had two previous repairs and three had four previous repairs. Of the 56 patients, 16 underwent oral mucosal graft urethroplasty, 15 onlay island flap, 14 parameatal flap, 10 tubularized incised plate urethroplasty, and 1 tubularized preputial flap. Complications were encountered in 16 (28.5%) patients in the form of graft contracture in 3, meatal stenosis in 2, urethral stricture in 2 including the patient with tubularized flap, urethra-cutaneous fistula in 7, bleeding in 1 and skin disruption in 1. The final complication rate was 25%. Conclusions: Decision making in redo hypospadias surgery depends mainly on local tissue availability and the degree of tissue scarring. The characteristics of oral mucosal graft make it suitable for urethroplasty in the absence of local donor tissues. A long-term follow up for redo hypospadias repair is required to assess the late neourethral stricture and residual penile curvature.

The Effect of Pre-Incision Urethral Plate Width and Granular Width on the Outcome of Tabularized Incised Urethral Plate Repair Surgery in Distal Penile Hypospadias, A Prospective Study

Annals of Urology & Nephrology, 2020

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 methods: The study was a prospective evaluation of patients operated for hypospadias. 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 tabularized 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 meat us at the tip of the glans with no stenosis, fistula or diverticulum. Results: All 38 patients were evaluated at 6 months and 1 year follows 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 patients (6.7 %), glans dehiscence 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). Conclusion: The pre-incision urethral plate width and granular width was not correlated with the TIP outcome. A better HOPE score is associated with wide urethral plate.

Effect of Suturing Technique and Urethral Plate Characteristics on Complication Rate Following Hypospadias Repair: A Prospective Randomized Study

The Journal of Urology, 2009

We studied the effect of suturing technique and the impact of urethral plate characteristics on the complication rate following tubularized incised plate urethroplasty. Materials and Methods: We prospectively studied 80 boys (mean age 4.5 years, range 3 to 7) with primary hypospadias in a randomized fashion between January 2004 and May 2005. Of the patients 64 had anterior and 16 had mid penile hypospadias. Patients were allocated into 2 groups according to suture technique, with continuous sutures used in 40 boys and interrupted sutures in 40. We evaluated urethral plate depth, length and width before and after incision. Correlation between suture technique, plate type, width and length, and complication rate was performed. Results: Mean followup was 3 years. Success rates were 90% and 69% for anterior and mid penile hypospadias, respectively (p ϭ 0.037). Complications developed in 11 patients (13.8%) and consisted of fistula (8), dehiscence (2) and meatal stenosis (3). On univariate analysis the suture technique, depth and length of urethral plate, width after incision and presence of hypoplasia had no impact on complication occurrence. However, urethral plate width before incision was significantly related to complication occurrence (p ϭ 0.048). Conclusions: Suture technique has no influence on the outcome of tubularized incised plate urethroplasty. Urethral plate characteristics do not affect the complication rate except for plate width, which significantly affects the outcome. Adequate urethral plate width (8 mm or greater) is essential for successful tubularized incised plate repair.

Comparison of Two Tubularized Incised Plate Urethroplasty Techniques in Hypospadias Reconstructive Surgery

2020

BACKGROUND Hypospadias repair is a challenging type of urogenital reconstructive surgery for which different techniques are currently used. The purpose of this study is to determine the outcomes of distal, mid-shaft and proximal hypospadias repair using two new variations of tubularized incised plate (TIP) urethroplasty (TIP-δ and TIP-ελ) and to compare their complication rates with other already known operative techniques made from the same surgical team. METHODS This study included 269 boys with hypospadias. The preoperative meatal site was distal in 179 patients, mid-shaft in 44 and proximal in 46. The average age at the operation was 17 months. The technique applied in distal hypospadias was Mathieu in 77 patients, Snodgrass in 28 and (TIP)-δ in 74. The technique applied in mid-shaft hypospadias was a tubularized island flap (TIF) in 12 patients, onlay island flap (OIF) in 5 and TIP-ελ in 27. The operative technique for proximal hypospadias was TIF in 15 patients, OIF in 10 and ...
