Correction of congenital penoscrotal webbing in children: A retrospective review of three surgical techniques

Evaluation of Z-plasty versus Heineke-Mikulicz scrotoplasty in the management of penoscrotal web in pediatric age group

BACKGROUND

The penoscrotal web may be congenital or acquired following excessive ventral skin removal during circumcision. Several surgical techniques were described for the treatment of congenital webbed penis without a clear comparison between their outcomes. This prospective study aimed at comparing the surgical results of Z-scrotoplasty and Heineke-Mikulicz scrotoplasty in the treatment of congenital webbed penis in uncircumcised pediatric patients.

METHODS

Our study included 40 uncircumcised patients who were divided randomly into two groups; Group A included 20 patients who were treated by Z-scrotoplasty and Group B included the other 20 patients who were treated by Heineke-Mikulicz scrotoplasty. All patients were circumcised at the end of the procedure.

RESULTS

The surgical outcome was good without a significant difference between the two groups in 36 patients. Recurrent webbing developed in one patient of Group A and in three patients of Group B (FE p = 0.605) The only significant difference between the two groups was the operative duration which was shorter in Group B than in Group A (P < 0.001*).

CONCLUSIONS

Treatment of congenital penoscrotal web in the pediatric age group could be done with either Z-scrotoplasty or Heineke-Mikulicz scrotoplasty with satisfactory results, however, without significant difference in the surgical outcomes.

Complications and troubleshooting in primary penile prosthetic surgery-a review

Penile implant surgery is the gold standard to treat erectile dysfunction with success rates of over 90%. The first penile implants were developed in the early 1900s. Since then, several types of implants have been developed including malleable implants, two-piece inflatable implants, and three-piece inflatable implants. The three-piece inflatable penile prosthesis, which was introduced in 1973, is the most widely used type of penile implant in the United States. Penile implant surgery has undergone numerous advancements over the years, improving outcomes and patient satisfaction. However, as with any surgical procedure, there are risks and complications associated with penile implant surgery. It is important for surgeons to understand these potential complications and to have strategies in place to manage and prevent them to achieve the best possible outcomes for their patients.

A Rare Case of Penoscrotal Webbing and Extensive Hernias: An Anatomical Report With Genetic Insights

During a routine anatomical dissection of an 81-year-old male cadaver received through the Gift Body Program of Saint Louis University School of Medicine (SLU SOM), a massive bulging in the abdominal area was observed that was consistent with numerous hernia repairs noted in the donor's self-reported medical history. Gross anatomical dissection of the cadaveric body revealed extensive herniation of portions of the small intestine and peritoneal sac along the costal margin and extending to the left aspect of the abdomen. Additionally, an uncircumcised phallus was buried within the suprapubic fat pad and demonstrated simple, grade III penoscrotal webbing (PSW), creating an impression of micropenis presence. To gain additional insights into the current case, analysis of the coding regions (exomes) of DNA procured from the body for putative genetic variants was performed using next-generation sequencing (NGS) technology. This analysis revealed 110 rare (minor allele frequency (MAF) ≤ 0.01), pathologic/deleterious genetic mutations. The most relevant variants to this case were the ones associated with male sexual development, BMP1 and BMP4; connective tissue development, COL3A1 and COL5A3; cilia morphogenesis and function, DNAH5 and MAPK15; as well as hormonal homeostasis, ESR1. Direct involvement of BMP1 both in male sexual development and hernia genesis makes it a strong candidate for linking the two pathologies, PSW and multiple hernias, observed in the present case. Yet the presence of a group of mutated genes linked to myopathies (ITGA7, NRAP, POLM, SCN5A, XIRP2) and muscular dystrophy (ITGA7) raises a question about the involvement of these muscular pathologies in hernia genesis and unsuccessful hernia repairs associated with the current case.

Heineke-Mikulicz Preputioplasty: Surgical Technique and Outcomes

OBJECTIVE

To provide a summary of surgical technique and outcomes for Heineke-Mikulicz preputioplasty (HMP), a foreskin-preserving surgical treatment for phimosis in the adult population.

METHODS

We retrospectively reviewed 7 patients who underwent HMP by a single surgeon from May 2017 to May 2021. Variables included patient demographics, intraoperative considerations, and post-operative course. HMP is performed using a 2-3 cm vertical incision over the phimotic band on the dorsal surface to just above Buck's fascia. Additional incisions are made on the ventral surface if phimosis remains persistent after dorsal release. The incision is closed horizontally in 2 layers.

RESULTS

Seven patients underwent HMP. Median age was 47.3 and median BMI was 24.3. Five patients reported bothersome phimosis and 1 each reported paraphimosis and frenular tethering. Six patients requested foreskin sparing surgery as a personal preference and 1 patient was an intraoperative consult. Topical betamethasone was attempted in 3 of 7 patients. The median time from diagnosis to surgery was 2 months. Median operative time was 45.5 minutes and median estimated blood loss was 5 mL. Two patients required both dorsal and ventral incisions. No intraoperative complications were reported and all patients were discharged the same day. At median follow-up of 1.8 months, 1 patient reported bothersome phimosis secondary to scar formation treated successfully with triamcinolone.

CONCLUSION

HMP is a safe and effective method of treating even very significant phimosis in patients trying to avoid circumcision or intraoperative consults where preferences may be unclear. Our method takes less time than traditional circumcision with a comparable recovery and complication profile.

Congenital webbed penis: Surgical outcomes of a simplified technique

BACKGROUND

Webbed penis is a cause of concealed penis. It reflects abnormal attachment of the scrotal skin to different ventral penile shaft levels, possibly due to abnormal scrotal dartos insertion. Different techniques are available for correction of congenital webbed penis. However, there is no single one versatile for correction of different grades.

OBJECTIVE

To evaluate the surgical outcome of penile degloving, excision of abnormal dartos fascia with penoscrotal fixation sutures to correct different grades of congenital webbed penis.

STUDY DESIGN

This prospective study was conducted on boys with congenital webbed penis. Thorough clinical examination to determine the degree of webbed penis and associated anomalies were done. A technical modification of previously described technique by Frenkl et al. 2004 (22) was used. The principles include; complete penile degloving with excision of all abnormal scrotal dartos attached to the penile shaft, creation of a well-defined penoscrotal angle by penoscrotal fixation sutures and the short ventral skin was compensated from the prepuce with circumcision. Assessments of surgical outcomes and parents' satisfaction were done during follow up visits.

RESULTS

This study included 107 boys. The median age was 9 (range, 6-40) months, and the median operative time was 55 (range, 50-65) min. Five patients (4.7%) developed self-limited postoperative penile edema, two (1.9%) developed wound infections, and two (1.9%) had a self-limited scrotal hematoma. The median follow-up period was 19 months. At the 6 months follow-up, we had two patients with persistent mild grade I webs, with a success rate of 98.13%. Parental satisfaction was obtained for all patients.

DISCUSSION

Currently, there is no current single technique suitable for the correction of all grades of webbed penis. In this study, we presented a technical modification of previously described technique by Frenkl et al. 2004 (9), this modified technique is versatile for correction of different grades of congenital webbed penis without leaving a scar at the penoscrotal angle. But, absence of a comparative group is considered a limitation; however, the versatility of this technique overcomes this limitation.

CONCLUSIONS

This described technique is simple and feasible. It could correct all types of congenital webbed penis. Short term outcome showed good cosmetic and functional results with parental satisfaction.

Is the simple webbed penis a contraindication to circumcision?

Background

Surgical correction of the webbed penis is challenging. We presented the safety and feasibility of webbed penis correction for neonates under local anesthesia using a simple principle of leaving equal cylindrical shaft skin.

Methods

This retrospective study included 530 patients who presented for circumcision to three pediatric surgery centers between May 2017 and January 2020. We included male patients aged less than four weeks old who had circumcision with a minimum of 6 months follow-up. We compared patients with normal penile anatomy (n = 451, Group 1) to a simple webbed penis (n = 79, Group 2).

Results

There were no differences in age and weight between groups. The procedure time was significantly longer in Group 2 (8.05 ± 3.11 vs. 7.48 ± 2.07 min; P = 0.04). There were no differences in bleeding (P = 0.38), redundant foreskin (P > 0.99), need for corrective surgery (P = 0.38), and re-suturing (P = 0.28) between groups. The procedure success was significantly higher in Group 1 (449 (99.56%) vs. 70 (88.6%); P < 0.001). Parents' satisfaction was measured at two weeks with no difference between both groups.

Conclusion

Simple penoscrotal web is not a contraindication for neonatal circumcision. Circumcision of the penoscrotal web had good esthetic results with comparable outcomes to those with a normal penis without a web.

Aesthetic Scrotoplasty: Systematic Review and a Proposed Treatment Algorithm for the Management of Bothersome Scrotum in Adults

BACKGROUND

Increased scrotal laxity is a poorly defined entity often associated with discomfort while wearing loose clothes, walking, doing sports and during intercourse. In our experience, this condition is produced by an enlarged scrotal bag hanging more than 1-2 cm below the tip of the penis and can be associated with persistent penoscrotal webbing. Our objective was to perform a systematic literature review addressing the diversity of this entity and its surgical treatment, as well as propose a diagnostic and therapeutic approach.

METHODS

A systematic search strategy was performed following PRISMA guidelines under the terms: Scrotum(Mesh), Plastic Surgery(Mesh), Reduction Surgery, Scrotoplasty, Ventral Phalloplasty, Scrotomegaly, Penoscrotal Web, Webbed Penis(Mesh), Scrotal Lifting, Scrotopexy and Scrotal Tuck. Articles referring to scrotum reduction or plasty in male genital rejuvenation context and ventral phalloplasty related to adult penoscrotal webbing correction were considered eligible for analysis. A management algorithm and surgical technique is proposed along with the results.

RESULTS

A total of 1430 articles were found. After removing duplicates and applying inclusion and exclusion criteria, 11 articles were eligible for analysis. Most articles corresponded to case reports or surgical technique descriptions. Based on correcting excessive scrotal skin and/or penoscrotal webbing, we propose a vertical midline scrotal skin resection and a penoscrotal junction Z plasty, respectively.

CONCLUSIONS

Aesthetic scrotoplasty and scrotal rejuvenation surgical techniques still remain as entities poorly addressed in the international literature. More reported experiences are needed in order to complement our proposed management algorithm and develop a nomenclature, diagnostic and treatment consensus.

Ontogeny of estrogen receptors in human male and female fetal reproductive tracts

This paper reviews and provides new observations on the ontogeny of estrogen receptor alpha (ESR1) and estrogen receptor beta (ESR2) in developing human male and female internal and external genitalia. Included in this study are observations on the human fetal uterine tube, the uterotubal junction, uterus, cervix, vagina, penis and clitoris. We also summarize and report on the ontogeny of estrogen receptors in the human fetal prostate, prostatic urethra and epididymis. The ontogeny of ESR1 and ESR2, which spans from 8 to 21 weeks correlates well with the known "window of susceptibility" (7-15 weeks) for diethylstilbestrol (DES)-induced malformations of the human female reproductive tract as determined through examination of DES daughters exposed in utero to this potent estrogen. Our fairly complete mapping of the ontogeny of ESR1 and ESR2 in developing human male and female internal and external genitalia provides a mechanistic framework for further investigation of the role of estrogen in normal development and of abnormalities elicited by exogenous estrogens.

Estrogens and development of the mouse and human external genitalia

The Jost hypothesis states that androgens are necessary for normal development of the male external genitalia. In this review, we explore the complementary hypothesis that estrogens can elicit abnormal development of male external genitalia. Herein, we review available data in both humans and mice on the deleterious effects of estrogen on external genitalia development, especially during the "window of susceptibility" to exogenous estrogens. The male and female developing external genitalia in both the human and mouse express ESR1 and ESR2, along with the androgen receptor (AR). Human clinical data suggests that exogenous estrogens can adversely affect normal penile and urethral development, resulting in hypospadias. Experimental mouse data also strongly supports the idea that exogenous estrogens cause penile and urethral defects. Despite key differences, estrogen-induced hypospadias in the mouse displays certain morphogenetic homologies to human hypospadias, including disruption of urethral fusion and preputial abnormalities. Timing of estrogenic exposure, or the "window of susceptibility," is an important consideration when examining malformations of the external genitalia in both humans and mice. In addition to a review of normal human and mouse external genital development, this article aims to review the present data on the role of estrogens in normal and abnormal development of the mouse and human internal and external genitalia. Based on the current literature for both species, we conclude that estrogen-dependent processes may play a role in abnormal genital development.

Surgical management of post-circumcision webbed penis in children

Objective

To report the outcomes of surgical correction of post-circumcision webbed penis using two previously described techniques: the Heineke-Mikulicz (HM) scrotoplasty and the multiple Z-plasty.

Patients and methods

A prospective study of children with post-circumcision webbed penis was conducted. The patients were classified into two groups according to the degree of web and the remaining ventral penile skin as to whether adequate or short after circumcision. Group I was repaired by HM scrotoplasty and in Group II the multiple Z-plasty technique was used.

Results

This study included 86 patients of whom 71 maintained follow-up; 44 (62%) in Group I and 27 (38%) in Group II. The median (range) operative time was 45 (30–55) min in Group I and 75 (60–90) min in Group II. Wound infection occurred in two (4.5%) patients in Group I. In Group II postoperative mild self-limited penile oedema was present in three patients (11.1%). A self-limited scrotal haematoma developed in two (7.4%) patients.

Conclusion

Correction of post-circumcision webbed penis in children can be done by one of two techniques: HM scrotoplasty in Grade 1 and multiple Z-plasty in Grade 2 and Grade 3, with favourable outcomes.

Androgen and estrogen receptor expression in the developing human penis and clitoris

To better understand how the human fetal penis and clitoris grows and remodels, we undertook an investigation to define active areas of cellular proliferation and programmed cell death spatially and temporally during development of human fetal external genitalia from the indifferent stage (8 weeks) to 18 weeks of gestation. Fifty normal human fetal penile and clitoral specimens were examined using macroscopic imaging, scanning electron microscopy and immunohistochemical localization for the cellular proliferation and apoptotic markers, Ki67 and Caspase-3. A number of hot spots of cellular proliferation characterized by Ki67 localization are present in the penis and clitoris especially early in development, most notably in the corporal body, glans, remodeling glanular urethra, the urethral plate, the roof of the urethral groove and the fully formed penile urethra. The 12-fold increase in penile length over 10 weeks of growth from 8 to 18 weeks of gestation based on Ki67 labelling appears to be driven by cellular proliferation in the corporal body and glans. Throughout all ages in both the developing penis and clitoris Ki67 labeling was consistently elevated in the ventral epidermis and ventral mesenchyme relative to the dorsal counterparts. This finding is consistent with the intense morphogenetic activity/remodeling in the ventral half of the genital tubercle in both sexes involving formation of the urethral/vestibular plates, canalization of the urethral/vestibular plates and fusion of the urethral folds to form the penile urethra. Areas of reduced or absent Ki67 staining include the urethral fold epithelium that fuses to form the penile tubular urethra. In contrast, the urethral fold mesenchyme is positive for Ki67. Apoptosis was rarely noted in the developing penis and clitoris; the only area of minimal Caspase-3 localization was in the epithelium of the ventral epithelial glanular channel remodeling.

A Modified Scrotoplasty for Treating Severe Penoscrotal Webbing in Children

To compare a novel modified W-incision scrotoplasty (MWS) operation method with the conventional V-Y scrotoplasty for treatment of severe penoscrotal webbing (PSW) in children a retrospective study was conducted on 26 children. Circumcision combined with modified scrotoplasty was used to repair the webbed penis and phimosis of children and another 32 patients undergoing V-Y scrotoplasty served as the control group. There was a statistically significant difference of angle improvements of penis and scrotum in a horizontal position (-66 ± 10; -57 ± 6, P < 0.001) and the parent satisfaction score (Five Likert Scale) (4.7 ± 0.56; 3.8 ± 0.47, P < 0.001) between the two groups. All 26 children who underwent MWS presented with no serious postoperative complications, and there was no significant difference in surgical complications compared to children treated with V-Y scrotoplasty.

Outcome of circumcision for newborns with penoscrotal web: oblique skin incision followed by penis shaft skin physical therapy shows success

SHORT INTRODUCTION/BACKGROUND: and objectives: Although it is widely agreed that newborn circumcision complications are low when the penile anatomy is normal, outcomes are uncertain when a web of skin attaches the penis to the scrotum. This anomaly, called a penoscrotal web or webbed penis, often leads to surgical reconstruction instead of newborn circumcision.

OBJECTIVE

With this study, the authors compare the circumcision success rate for webbed penis circumcisions using a new, alternate method vs that using the traditional method.

STUDY DESIGN

Data from circumcision patients presenting to the Division of Urology's circumcision clinic from January 2014 to April 2018 were reviewed. All patients who met the checklist criteria for suitability to circumcise were enrolled in the study. They were grouped into the 'normal' group if they had no penile anomalies or the 'web' group if they had a web with a straight penis. Cases with penile anomalies were excluded. The new circumcision method includes altering the circumcision site planned to be oblique, slant up, to compensate for the web, retaining slightly more ventral than dorsal shaft skin, and including home care skin physical therapy as 'push down' the shaft skin. Postcircumcision evaluation was completed within 2 weeks after circumcision, and families were followed up as needed over the study period, six months after circumcision. Circumcision success was defined as the penis shaft no longer attached to the scrotum and circumcision line below the glans corona.

RESULTS

Of 828 boys who presented for circumcision, 652 (79%) were enrolled as they were suitable for circumcision: 355 (43%) in the normal group and 297 (36%) in the web group. The remaining 176 (21%) were excluded because they presented with a penile anomaly: buried penis (125), chordee (40), and hypospadias (11). Follow-up was carried out for 6 months. In the web group, follow-up data were obtained for 263 of 297 (89%) cases, with 261 of 263 (99%) showing success, and in the normal group, follow-up data were obtained for 327 of 355 (92%) cases, with all 327 (100%) showing success. The two web group cases (0.7%) who failed had surgical reconstruction.

DISCUSSION

It is believed the high success rate for penoscrotal web circumcisions with oblique incision followed by penis shaft skin physical therapy establishes that surgical reconstruction is not required in most of these cases.

CONCLUSION

It was found that newborns with a penoscrotal web and straight shaft show 99% success for circumcision, which is not different from boys without any penile anomalies (p = not significant). The authors believe the adoption of these new, alternate circumcision methods will enable boys with a web to avoid surgical reconstruction.

Scrotal injuries during neonatal circumcision

OBJECTIVE

To report very rarely encountered scrotal injuries during neonatal circumcision. Hospitals and physicians in the authors' country are mandated to report circumcision complications to the Ministry of Health. Those reports include the discharge summary from the emergency room or the admitting department. This is believed to be the first case series describing scrotal injuries during ritual circumcision.

PATIENTS AND METHODS

Reports of all circumcision complications between 2007 and 2014 were evaluated. Retrieved data on cases of scrotal injuries included patient's age, time between injury and hospital admission, nature of the injury, and administered treatment.

RESULTS

Twelve of a total of 489 reports of circumcision injuries involved the scrotum (2.5%). All circumcisions were performed during the neonatal period, and the infants were admitted on the day of injury. The only related genital injury was significant shortage of penile skin reported in six patients. Scrotal exploration and skin closure in the operating room was undertaken in six cases, five under general anesthesia. Suture closure in the emergency department was performed in three patients, and the scrotal skin was left to heal with secondary intention in three other patients. Scrotal content injury that extended to the tunica vaginalis of the testis was noted in one exploration.

DISCUSSION

The injuries sustained by the 12 study infants were mostly superficial and are not expected to cause long-term damage, although half of the patients required treatment under general anesthesia in the operating room or under sedation in the emergency department. While all reported patients emerged unscathed from the anesthetic procedures, the possible immediate complications of anesthesia as well as its long-term effects are not to be taken lightly, especially when treating a newborn. Further education of medical providers as well as performers of ritual circumcisions may help lower the risk of this rare injury as well as other more severe complications.

CONCLUSION

Scrotal injury during neonatal circumcision is rare. While half of the 12 reported patients required exploration in the operating room, the injuries were mostly superficial and did not involve scrotal content, although they often involved extensive resection of penile skin.
