Tian G, Guo B, Zhang L. Analysis of influencing factors of multiple urethrocutaneous fistula after urethroplasty in children with hypospadias. Front Pediatr 2023; 11:1103200. [PMID: 37025285 PMCID: PMC10072279 DOI: 10.3389/fped.2023.1103200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2022] [Accepted: 03/01/2023] [Indexed: 04/08/2023] Open
Abstract
Objective The objective of this study was to investigate the influencing factors of multiple urethrocutaneous fistula (UF) after urethroplasty in children with hypospadias. Methods The clinical data of 195 children with UF after urethroplasty treated surgically in the Third Affiliated Hospital of Zhengzhou University from August 2015 to August 2022 were retrospectively analyzed and divided into the single UF group (n = 134) and the multiple UF group (n = 61) according to whether multiple UF occurred after urethroplasty. The possible correlated factors were collected and compared between the two groups, including hypospadias degree, length of formed urethra, time of urethroplasty, pre-urethroplasty weight, age at urethroplasty, urethroplasty style, season of urethroplasty, the first fistula repair method, season of the first fistula repair, diameter of the largest fistula of the first fistula repair, time of the first fistula repair surgery, and other 13 factors. Results By univariate analysis, statistically significant differences were found between the two groups in age at urethroplasty, length of the formed urethra, method of urinary drainage after urethroplasty, whether or not purulent urethral drainage after first fistula repair was present, the first fistula repair method, and diameter of the largest fistula of the first fistula repair (P < 0.05). After multifactorial analysis, the independent risk factors associated with multiple UF after urethroplasty were determined to be use of a vesicostomy tube as the urinary drainage method after urethroplasty (P < 0.05, OR = 6.574, 95% CI: 2.720-15.891) and the presence of purulent urethral drainage after first fistula repair (P < 0.05, OR = 2.723, 95% CI: 1.214-6.109). Conclusions A catheter as the drainage method after urethroplasty is an independent protective factor for multiple urethrocutaneous fistula, and the existence of purulent urethral secretions after the first fistula repair is an independent risk factor.

Abstract
PURPOSE We report the efficacy of pre- and post-operative showering for preventing surgical site infections (SSIs) and urethrocutaneous fistula after hypospadias surgery. MATERIALS AND METHODS In 2006, standardised pre- and postoperative showering was introduced for hypospadias patients. Showering involves washing the genitals and groin 2 h preoperatively as well as immediately after the removal of a stent postoperatively. Data from 520 procedures performed on 376 hypospadias patients by a single surgeon from 1996 to 2015 were collected prospectively. The shower (S) group comprised 258 patients (372 procedures) and the nonshower group comprised 118 patients (148 procedures). Management protocols were identical for two groups. RESULTS Patient demographics were similar. SSIs were significantly less in the S group (0% vs. 2.0%; P < 0.05). The incidence of fistulas was lower in the S group (2.0% vs. 6.3%). The mean duration of follow-up was significantly shorter in the S group (3.6 vs. 12.8 years; P < 0.05) but longer than the mean time taken for complications to develop (0.4 years). CONCLUSIONS Our results suggest that pre- and post-operative showering may contribute to preventing SSIs and fistulas in hypospadias patients.

Comparison of Penile Appearance and Outcomes Between Prefabricated Urethra and Pre-implanted Urethral Plate for Treatment of Children With Severe Hypospadias: A Retrospective Study. Front Pediatr 2021; 9:719551. [PMID: 34595144 PMCID: PMC8476890 DOI: 10.3389/fped.2021.719551] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Accepted: 08/23/2021] [Indexed: 11/13/2022] Open
Abstract
Objective: To compare the effect of prefabricated urethra and pre-implanted urethral plate in the treatment of severe hypospadias in children. Methods: We retrospectively analyzed the clinical data of 53 patients who diagnosed as severe hypospadias underwent staging urethroplasty from January 2015 to January 2018 in the Department of Pediatric Surgery, First People's Hospital, Zunyi City. The patients were divided into two groups: group A (n = 25) were treated with prefabricated urethra and group B (n = 28) were treated with pre-implanted urethral plate. After the second stage surgery, the ratios of complications such as urethral fistula, urethral stenosis, urethrocele, and recurrence chordee were compared. The penis was scored from meatus, glans, shaft skin, general appearance by the parents, blinded urologists according to The Pediatric Penile Perception Score, and the scores were compared too. Results: All patients were followed up after two stage operations for an average of 28 months. Glans dehiscence occurred in two patients (8%), urethral orifice stenosis occurred in one (4%) and urethral fistula occurred in three (12%) in group A. No urethral stenosis, urethrocele and recurrence chordee was observed. One patient presented urethral plate inactivation (3.6%), two patients presented urethral fistula (7.1%) and one patient presented urethral stenosis (3.6%) in group B. No urethrocele, glans dehiscence and recurrence chordee was observed. The total complication rate in group A was 24 and 14.3% in group B, respectively, and the difference was not statistically significant (P = 0.582). The differences between two groups scored by parents in glans (P = 0.030) was statistically significant. The differences between two groups scored by operators in meatus (P = 0.041), shaft skin (P = 0.000), glans (P = 0.001), and general appearance (P = 0.007) were statistically significant. The differences between two groups scored by counterparts in meatus (P = 0.006), shaft skin (P = 0.003), glans (P = 0.010), and general appearance (P = 0.014) were statistically significant. Conclusion: Both prefabricated urethra and pre-implanted urethral plate methods are suitable for correction of severe hypospadias as staging surgery in children. In general, pre-implanted urethral plate is more worthy of spread because it is much more applied in patients with small glans and achieve good appearance of penis.

[PMID: 33263516 DOI: 10.5152/tud.2020.20323] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Accepted: 11/10/2020] [Indexed: 11/22/2022]
Abstract
OBJECTIVE This study aimed to investigate the risk factors of fistula recurrence after primary urethrocutaneous fistulectomy in children with hypospadias. MATERIAL AND METHODS The study included 63 children who underwent fistulectomy for urethrocutaneous fistula (UCFs) that occurred after urethroplasty for hypospadias, between February 2009 and December 2018. The patients were divided into 2 groups: successful group 1 and failed group 2. For data analysis, we included the demographics of the patients, the details of the previous urethroplasty (the type of hypospadias and the location of the meatus after complete chordectomy), the presence of meatal stenosis or urethral stricture after urethroplasty, and the size of the UCFs. The Student t-test and the chi-square test were performed to analyze the data using the Statistical Package for Social Sciences software. RESULTS The overall success rate of primary urethrocutaneous fistulectomy was 81.0% (51/63 children). The most common location of a secondary fistula was the penoscrotal area 5 (41.6%). There were no statistically significant differences in age (p=0.501), weight (p=0.063), body mass index (p=0.924), history of low birth weight (p=0.454), and history of prematurity (p=0.381). The type of hypospadias (p=0.007) and urethral defect length (p=0.021) were identified as independent risk factors for failed urethrocutaneous fistulectomy. There were no statistically significant differences in meatal stenosis (p=0.431), postoperative stricture (p=0.587), fistula location (p=0.173), multiplicity (p=0.588), and fistula size (p=0.530). CONCLUSION The type of hypospadias and the length of the urethral defect are the significant risk factors for secondary fistula recurrence after primary urethrocutaneous fistulectomy.

Risk factors for failed urethrocutaneous fistula repair after transverse preputial island flap urethroplasty in pediatric hypospadias. Int Urol Nephrol 2017; 50:191-195. [PMID: 29282594 DOI: 10.1007/s11255-017-1773-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2017] [Accepted: 12/12/2017] [Indexed: 10/18/2022]
Abstract
OBJECTIVES We review our experience in urethrocutaneous fistula (UCF) repair after transverse preputial island flap urethroplasty (Duckett) in pediatric hypospadias to investigate the risk factors for unsuccessful outcome. METHODS Two hundred and nineteen UCFs repairs conducted in our center from January 2015 to December 2016 after Duckett technique were retrospectively reviewed and 182 had a follow-up for more than 6 months. The age of patients, size, localization and numbers of UCFs, interval time of two operations, length of neourethra, times of UCFs repairs, complications other than UCFs, hospital of primary surgery and postoperative infection were analyzed as potential risk factors. Stratified analysis and assessment of additive interaction were performed to have a better understanding of the relation between the risk factors. Logistic regression analysis was used for multivariate analysis. RESULTS UCF repairs were succeeded in 121 (66.5%) and failed in 61 (33.5%) at first operation. In the univariate analysis, size and numbers of UCFs (P = 0.01 and P = 0.035, respectively), interval time of two operations (P = 0.042) and hospital of primary surgery (P = 0.02) were statistically related with the outcome. In the multivariate analysis, UCF ≥ 2 (OR 2.71, 95%, CI 1.095-6.692, P = 0.031), size ≥ 2 mm (OR 2.45, 95% CI 1.267-4.757, P = 0.08) and primary surgery not at our hospital (OR 2.21, 95% CI 1.094-4.126, P = 0.026) were identified as independent risk factors for unsuccessful outcome. In the stratified analysis, multiplicative interaction between the 3 risk factors was not found. CONCLUSIONS Our study suggested that UCF repairs after transverse preputial island flap urethroplasty were easier to fail if the UCF was ≥ 2 mm, the numbers of UCFs was ≥ 2, or the surgeon had less experience. The age of patients, site of UCFs, interval time of two operations, length of neourethra, times of UCFs repairs, complications other than UCF and postoperative infection were not significantly related to the success rate of UCF repair.

Correction of penile ventral curvature in patients with minor or no hypospadias: a single surgeon's experience of 43 cases. Pediatr Surg Int 2016; 32:975-9. [PMID: 27488311 DOI: 10.1007/s00383-016-3950-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 07/23/2016] [Indexed: 10/21/2022]
Abstract
PURPOSE To report our experience of correcting penile ventral curvature associated with minor or no hypospadias. METHODS We reviewed 43 penile ventral curvature patients treated by a single surgeon from 1997 to 2015. Of these, 23 had minor hypospadias. Curvature was corrected using degloving, chordectomy, dorsal plication (DP), tunica albuginea incision (TAI), or a combination of these. Outcome was confirmed by induced artificial erection and post-operative appearance. RESULTS Mean age at curvature correction was 3.2 ± 2.6 years. 17/43 had degloving and chordectomy (DC), 16/43 had DP after DC, and 10/43 had TAI after DC, because of ventral shortening and severe curvature caused by a short hypoplastic urethra. Other procedures required were primary meatoplasty (n = 4) and urethroplasty (UP; n = 1) at the time of curvature correction, and UP after correction of curvature (n = 11). Complications included recurrence of curvature after DP (n = 3/16; 18.8 %) and urethral stenosis after UP with tubed peritoneum (n = 1/10; 10 %). There were no recurrences of curvature in TAI cases. Parents reported penile cosmesis as good (n = 38; 88.4 %), acceptable (n = 4; 9.3 %), or poor (n = 1; 2.3 %). CONCLUSION We recommend TAI followed by UP for correcting penile ventral curvature with short hypoplastic urethra. Tubed peritoneum is not recommended for UP.
