Surgery to the external genitalia

Urogenital sinus malformation: From development to management

Urogenital sinus (UGS) malformation, also known as persistent urogenital sinus (PUGS), is a rare congenital malformation of the urogenital system. It arises when the urethra and vaginal opening fail to form properly in the vulva and fuse incorrectly. PUGS can occur as an isolated abnormality or as part of a complex syndrome, and is frequently associated with congenital adrenal hyperplasia (CAH). The management of PUGS is not well-established, and there are no standardized guidelines on when to perform surgery or how to follow up with patients over the long term. In this review, we discuss the embryonic development, clinical evaluation, diagnosis, and management of PUGS. We also review case reports and research findings to explore best practices for surgery and follow-up care, in hopes of increasing awareness of PUGS and improving patient outcomes.

Lifelong Congenital Urology: The Challenges for Patients and Surgeons

CONTEXT

Patients born with complex congenital genitourinary anomalies (including bladder exstrophy, cloacal exstrophy, epispadias, neurogenic bladder, hypospadias and posterior urethral valves) often require major reconstructive surgery in childhood. These conditions, their treatment and sequelae require lifelong follow-up. This has created the need for adult urologists to provide care as these patients grow into adults.

OBJECTIVE

To evaluate current strategies for transition and provide a current position statement with examples of the challenges faced by patients and their health care teams as a result of these conditions and their treatment.

EVIDENCE ACQUISITION

Each of the authors was asked to provide a 500-word synthesis, based on current literature; to highlight the challenges faced in an area of their expertise.

EVIDENCE SYNTHESIS

The authors assembled in March 2018 to form a consensus based on the data gathered. The aforementioned sections were reviewed and following the consensus discussion the paper was formulated and reviewed.

CONCLUSIONS

Lifelong care of congenital problems is challenging and essential for many but not all. Expertise is needed to provide the best care for patients and make the best use of resources. Specialist centres appear to be the most effective and safe model. In the long term it would be ideal to establish an evidence base focused on the common long-term problems with these conditions to ensure excellent care with appropriate expertise.

PATIENT SUMMARY

Patients born with complex congenital anomalies of the genitourinary system require specialist care in childhood. Many will need lifelong care to manage their condition and the treatment of it. There is growing interest in this area of medicine and this consensus statement addresses the need for lifelong care in this group. The aim is to ensure that all patients that need care at any age are able to find what they need.

Long-term outcome of male genital reconstruction in childhood

Hypospadias, epispadias with or without exstrophy, and disorders of sex development are among the most common anomalies of genitalia that occur during childhood. Considering the tremendous effect of genitourinary reconstruction on adult life, the evaluation of the long-term results of different techniques of genitoplasty in pediatrics is of the utmost importance. After reviewing the literature, the authors summarize the available long-term outcomes of genitoplasty in childhood, specifically focusing on the cosmetic, psychosocial, psychosexual and functional results, and emphasize that, contrary to the widely available data on early outcomes of genital reconstruction in the pediatric population, very few well described controlled studies have evaluated the long-term effect of genitoplasty in puberty and adulthood, in the sense that the surgeon should describe the peroperative findings in more detail and also be more structured in evaluating the postoperative result at follow-up visits. Finally, the authors conclude that more attention should be paid to the impact of these techniques on cosmetic aspects and psychosexual development in these patients after puberty, as they play a crucial role in their adult quality of life.

Use of forearm free-flap phalloplasty in bladder exstrophy adults

OBJECTIVE

To assess the long-term outcome and cosmetic results of forearm free-flap phalloplasty for correcting micropenis associated with bladder exstrophy in men.

PATIENTS AND METHODS

From 1992 to 2000, six men with bladder exstrophy and unsatisfactory penile appearance underwent phalloplasty at our institution. The mean (range) follow-up was 113 (62-153) months. The surgical procedure consisted of a modified radial free-flap phalloplasty and prosthesis implantation. One-stage urethroplasty was electively performed according to the patient's voiding pattern. Early and late complications were recorded and quality of life after phalloplasty was assessed.

RESULTS

The mean (range) age was 21.2 (17-26) years and flap survival was 100%. Two incontinent patients underwent immediate perineal urethrostomy. One sepsis occurred, requiring the removal of the penile prosthesis and a cutaneous continent urinary diversion; this patient was the only one to complain about the outcome. Two anastomotic urethral strictures were conservatively treated by endoscopic urethrotomy and only one patient underwent subsequent urethral self-dilatations. Five patients were very satisfied with the cosmesis of the neophallus and three patients reported having regular sexual intercourse.

CONCLUSIONS

Although short, this series indicates the low incidence of early complications and the excellent long-term satisfaction with forearm free-flap phalloplasty in bladder exstrophy. Phalloplasty has potential indications when adult exstrophy patients are dissatisfied with the cosmetic appearance of their external genitalia or have unsatisfactory sexual intercourse.

Comparison of dressing removal following hypospadias repair

Hypospadias occurs when the urethral folds fail to fuse on the ventral aspect of the penis (Thomas and Barker, 1997). Surgical repair is often warranted and standard postoperative practice in the UK often includes the application of a dressing around the penis. This article reports the outcome of a small randomized controlled feasibility study to compare two methods of dressing removal following hypospadias repair. The same dressing was used throughout the study--a control group used a standard method of dressing removal, while an experimental group had an additional barrier film applied before the dressing was attached to the wound. The primary outcome measure was the time taken to remove the dressing. The time interval between starting the process of dressing removal and having no dressing left in place was used for statistical analysis. Secondary measures included assessment of the child's pain at different intervals by the parents and by an independent nurse observer. General discussion took place with the parents regarding any experience of anxiety. This was to assess whether parental anxiety should be measured in a future randomized controlled trial (RCT). There appeared to be implications with regard to time savings with the new method of dressing removal. Issues about the most suitable environment to remove dressing and differences between pain assessments of nurse and parent are noted. This was only a small-scale study. To investigate these issues more fully, a RCT has since been developed, has gained ethical approval and is due to start in August 2003.
