Comparison of dressing removal following hypospadias repair

The Role of Postoperative Dressing in Hypospadias Surgery: A Systematic Review and Meta-analysis of the Pediatric Literature

This study aimed to describe the available dressings and their management in patients undergoing hypospadias repair and compare postoperative outcomes with and without dressing and between the different dressing types. A comprehensive electronic literature search of PubMed, Embase, and Cochrane Library was conducted to obtain studies, published in the period 1990 to 2021, reporting on the dressing used following hypospadias surgery. All information regarding the dressing was considered as primary endpoints, whereas surgical outcomes were assessed as secondary outcomes. Thirty-one studies containing 1,790 subjects undergoing hypospadias repair were included. Dressings were divided into three categories: nonadherent to the wound, adherent to the wound, and glue-based dressings. Most authors preferred to remove/change the dressing in the ward and the median time of removal/change was 6.56 postoperative days. The dressing removal appeared as the most frequent factor generating parental anxiety. The median rate of wound-related complications was 8.18%, of urethroplasty complications 9.08% and of reoperations 8.18%. Meta-analysis of outcomes showed higher risk of reoperations using conventional dressing, with no differences in urethroplasty and wound-related complications rates between conventional and glue-based dressings. Furthermore, the use of dressing reported increased risk of wound-related complications compared with no dressing, without significant differences regarding occurrence of urethroplasty complications and reoperations. The current evidence confirmed that there is no difference in outcomes of hypospadias repair depending on a certain dressing type. To date, surgeon's preference remains the main factor determining the choice for a specific dressing or for no dressing at all.

Hypospadias and Increased Risk for Psychiatric Symptoms in Both Childhood and Adolescence: A Literature Review

Hypospadias is one of the most common congenital malformations in boys. Due to abnormal appearance in the penis with abnormal urination and erection, patients with hypospadias were vulnerable to suffering from stress and psychiatric difficulties. The present study aims to summarize all the current evidence of the association between hypospadias and the risk of psychiatric disorders by a comprehensive review. Seventeen clinical studies were identified in the four electronic databases. A total of 953,872 participants were involved, while 15,729 of them were hypospadiac patients and the remaining 938,143 were normal controls. The standard age for surgery for hypospadias ranged from 20.4 months to 21.5 years. Eight out of seventeen (8/17, 47%) included studies explicitly showed that patients with hypospadias had a significantly higher risk of psychosocial disorders (all P < 0.05). Specific types of psychiatric disorders included depression, anxiety, shyness, timidness, isolation, fear of ridicule, attention-deficit hyperactivity, autism spectrum, behavioral/emotional disorders, temper tantrums, emotionality, affective, psychosexual problems, and suicidal tendencies. Based on this review, psychiatric illnesses are frequently detected in hypospadiac patients' childhood, thus proper psychiatric guidance and early interventions from physicians, nurses, and parents may help these children to grow into less affected men.

Evaluation of a New Tubular Finger Oxygen-Enriched Oil Inside-Coated Dressing Device in Pediatric Patients Undergoing Distal Hypospadias Repair: A Prospective Randomized Clinical Trial Part II

Background: This study was the second part of a prospective randomized clinical trial and aimed to evaluate the use of a tubular finger oxygen-enriched oil inside-coated dressing device and its effect on the post-operative outcome of children undergoing distal hypospadias repair. Methods: A prospective single-blinded randomized clinical trial was carried out between September 2019 and September 2020. We included all patients with distal hypospadias, who received Snodgrass urethroplasty and preputioplasty. The patients were randomized in two groups according to the type of dressing: tubular finger oxygen-enriched oil inside-coated device (G1) and elastic net bandage with application of oxygen-enriched oil-based gel (G2). The patients were evaluated at 7, 14, 21, 30, and 60 post-operative day (POD). Results: Sixty-four patients (median age 14 months) were included in the study and randomized in two groups, each of 32 patients. Post-operative preputial edema rate was significantly lower in G1 (3/32, 9.3%) compared with G2 (10/32, 31.2%) (p = 0.001). The median duration of preputial edema was significantly shorter in G1 compared with G2 (6 vs. 10.5 days) (p = 0.001). Penile diameter measurements at 4th, 7th, 14th POD proved that entity and duration of post-operative swelling were objectively decreased using the new dressing. The wound healing was significantly faster in G1 compared with G2 (14.2 vs. 18.5 days) (p = 0.001). The post-operative complications rate was significantly lower in G1 (0%) compared with G2 (3/32, 9.3%) (p = 0.001). Foreskin dehiscence occurred in two G2 patients (6.2%) whereas, breakdown of urethroplasty and preputioplasty occurred in one G2 patient (3.1%) due to scratching injuries. The dressing management was subjectively assessed by nurses to be easier in G1 patients compared with G2 ones (median score 1.2 vs. 3.5) (p = 0.001). The median treatment costs were significantly lower in G1 compared with G2 (55 vs. 87 eur) (p = 0.001). No adverse skin reactions occurred. Conclusions: Post-operative dressing using tubular finger oxygen-enriched oil inside-coated device was highly effective, easy to manage, cheaper and associated with a lower rate of foreskin and urethral complications compared with the standard dressing method in pediatric patients undergoing distal hypospadias repair. It was also clinically safe without allergy or intolerance to the product.

Evaluation of efficacy of oxygen-enriched oil-based gel dressing in patients who underwent surgical repair of distal hypospadias: a prospective randomised clinical trial

Purpose

This study aimed to evaluate the efficacy of oxygen-enriched oil-based gel dressing on wound healing and postoperative outcome in children who underwent distal hypospadias repair.

Methods

We included all patients with distal hypospadias, who underwent Snodgrass urethroplasty and preputioplasty over an 18-months period. The patients were randomized in two groups according to the type of medication: oxygen-enriched oil-based gel (G1) and hyaluronic acid cream (G2). After discharge, parents changed the dressing twice a day for 2–3 weeks postoperatively. The patients were evaluated at 7, 14, 21, 30, 60 and 180 postoperative days and thereafter annually.

Results

One-hundred and fourteen patients (median age 18 months) were included in the study and randomized in two groups, each of 57 patients. The wound healing was significantly faster in G1 compared with G2 (p = 0.001). G1 reported significantly higher SWAS and modified HOPE scores compared with G2 (p = 0.001) at all steps of follow-up. No adverse skin reactions occurred. Foreskin dehiscence and re-operations rates were significantly lower in G1 compared with G2 (p = 0.001). Postoperative foreskin retractability was better in G1, with a significantly higher incidence of secondary phimosis in G2 (p = 0.001). The median treatment costs were significantly lower in G1 compared with G2 (p = 0.001).

Conclusion

Postoperative dressing using oxygen-enriched oil-based gel was highly effective, promoting a faster wound healing in patients who underwent distal hypospadias repair. It reported a lower incidence of foreskin dehiscence and better foreskin retractability compared with the control group. It was cost-effective and clinically safe without allergy or intolerance to the product.

A wet dressing for male genital surgery: A phase II clinical trial

Purpose:

This study was to confirm the safety and efficacy of BC dressing when used in surgical male wound healing at the urogenital area.

Methods:

Open, non-controlled clinical study of phase II. A total of 141 patients, among those children, adolescents and adults with hypospadias (112), epispadias (04), phymosis (13) and Peyronie's disease (12) that had a BC dressing applied over the operated area after surgery. A written informed consent was obtained from all participants. Study exclusion criteria were patients with other alternative treatment indications due to the severity, extent of the injury or the underlying disease. The outcomes evaluated were efficacy, safe and complete healing. The costs were discussed.

Results:

In 68% patients, the BC dressing fell off spontaneously. The BC was removed without complications in 13% of patients at the outpatient clinic during the follow-up visit and 17% not reported the time of removal. In 3% of the cases, the dressing fell off early. Complete healing was observed between 8th and 10th days after surgery. The BC dressings have shown a good tolerance by all the patients and there were no reports of serious adverse events.

Conclusion:

The bacterial cellulose dressings have shown efficacy, safety and that can be considered as a satisfactory alternative for postoperative wound healing in urogenital area and with low cost.

A prospective randomized trial of the effect of a soluble adhesive on the ease of dressing removal following hypospadias repair

AIM

To determine whether the use of a novel dressing removal technique resulted in shorter removal times, reduced the child's experience of pain and/or reduced parental anxiety when compared to a standard approach.

METHODS

This prospective unblinded randomized controlled trial of 53 consecutive boys undergoing primary hypospadias repair was powered using data from a prior feasibility study. Children were randomized to a standard control dressing (A) or standard dressing plus Cavilontrade mark (B) group. Removal was by (A) soaking the child and dressing in the bath or (B) application of an adhesive remover to the dressing. The primary outcome measure was dressing removal time. Secondary measures were: child pain scores on a visual analogue scale measured by the parent and nurse, and parental anxiety using the self-evaluative state anxiety measure. Data are expressed as median (range); P<0.05 is significant.

RESULTS

Dressing B was significantly quicker to remove than A: B 30 min (5-86 min) vs A 40 min (17-105 min), P=0.01, Mann-Whitney. No differences in parent/nurse pain scores between the two groups were seen. There was a strong correlation between parent and nurse reporting of pain scores at the time of dressing removal (Spearman 0.79, P<0.000). No significant differences in pre- and post-dressing removal parental anxiety scores were seen (P=0.159, Mann-Whitney). Several parents had high anxiety levels at both times.

CONCLUSION

The novel dressing removal approach (B) was significantly shorter than the standard one (A). There were no significant differences in child's pain or parental anxiety score between the two approaches.
