Primary non-refluxing megaureter: Natural history, follow-up and treatment.

Primary non-refluxing megaureter (PMU) is a congenital dilation of the ureter which is not related to vesicoureteral reflux, duplicated collecting systems, ureterocele, ectopic ureter, or posterior urethral valves and accounts for 5 to 10% of all prenatal hydronephrosis (HN) cases. The etiology is a dysfunction or stenosis of the distal ureter. Most often PMU remains asymptomatic with spontaneous resolution allowing for non-operative management. Nevertheless, in selective cases such as the development of febrile urinary tract infections, worsening of the ureteral dilatation, or reduction in relative renal function, surgery should be considered. CONCLUSION: Ureteral replantation with excision of the dysfunctional ureteral segment and often ureteral tapering is the gold-standard procedure for PMU, although endoscopic treatment has been shown to have a fair success rate in many studies. In this review, we discuss the natural history, follow-up, and treatment of PMU. WHAT IS KNOWN: • PMU is the result of an atonic or stenotic segment of the distal ureter, resulting in congenital dilation of the ureter, and is frequently diagnosed on routine antenatal ultrasound. WHAT IS NEW: • Most often, PMU remains asymptomatic and clinically stable, allowing for non-operative management. • Nevertheless, since symptoms can appear even after years of observation, long-term ultrasound follow-up is recommended, even up to young adulthood, if hydroureteronephrosis persists. • Ureteral replantation is the gold standard in case surgery is needed. In selected cases, however, HPBD could be a reasonable alternative.

Frank B. Bicknell: Pioneer in Pediatric Urology and Founder of the American Urological Association History Forum.

OBJECTIVE: To explore and document the life and urologic contributions of Dr. Frank B. Bicknell. METHODS: We researched the life of Dr. Bicknell via his publications, archived documents from the Didusch Museum and through the description of his life and accomplishments by his colleagues including John K. Lattimer and Frank Hinman Jr. RESULTS: Frank B. Bicknell (1907-1999) attended the University of Michigan (1925-1928) and Universityof Michigan Medical School (1928-1932) prior to his internship and urology residency at the Receiving Hospital, Detroit, Michigan (1932-1936). He served in the Merchant Marine in the 1930s, sailing around the world. He was a major in World War II and served as Professor of Urology at Wayne State University. In 1951 Dr. Bicknell got together a small group of eight urologists interested in pediatric urology during the AUA Annual Meeting. Drs. Campbell, Barber, Johnson, Mertz, Hinman Jr., Spence and Lattimer all met in Dr. Bicknell's Chicago hotel room and would form The Society for Pediatric Urology. At the time, Dr. Bicknell's brother-in-law had just become president of the American Academy of Pediatrics (AAP). Dr. John Lattimer with the help of Dr. Bicknell's brother-in-law was able to get a room at the AAP meeting which he filled with 2500 people, thought to be the largest collection of urologists in one room at the time. The success of the session led the AAP to develop a Section of Urology and impressed upon the AUA the magnitude of interest in pediatric urology. This allowed pediatric urologists to secure an exclusive session on the day before the main AUA meeting which has persisted since that time.Dr. Bicknell founded the History Forum in 1966 and chaired this very popular event during its first decade. The forum now occupies an entire afternoon during the AUA annual meeting, with papers presented on historic urologic topics. The highlight of this assembly is the annual lecture on the history of medicine. In 2000, this oration was renamed the Frank Bicknell History of Urology Oration to honor the founder of the History Forum. CONCLUSION: Dr. Frank Bicknell was an early leader in pediatric urology and urologic history who helped found The Society of Pediatric Urology and the AUA History Forum.

The history of the pediatric inguinal hernia repair.

The history of inguinal hernia repair is a rich one. For centuries, hernia healers, doctors, anatomists, surgeons and quacks have been devoted to this pathology that has afflicted mankind throughout its evolution. The development of surgical correction mainly focused on adult pathology, with treatments that often involved the loss of the testis. Hernia management in children, however, also dates from antiquity. Described as a swelling on the surface of the belly in ancient papyri, it was treated with tight bandages by the early physicians of Alexandria. For centuries, conservative treatment had been used for the child using primordial trussess, many prayers, and often pagan rituals as the arboreal passage of children described by Marcello of Bordeaux, doctor of the Emperor Theodosius I (347-395 AD), reserving medical intervention only for cases of strangulation in which only reduction was attempted. The middle ages were characterized by an increase in cultural and scientific exchange, during which the first comprehensive surgical textbooks and atlases were written. Different approaches to the inguinal hernia were not taught and passed down through generations of surgeons. The modern era brought a better understanding of the inguinal anatomy, which led to surgical techniques associated with less post-operative complications. Today, the pediatric inguinal hernia repair is one of the most common pediatric operations performed. It is considered a safe procedure with very low complication rate.

Neo-phalloplasty in children and adolescents for acquired penile loss.

INTRODUCTION: From 2000 to 2019, the De Castro's neo-phalloplasty was used in 47 patients with congenital and acquired penile loss. PURPOSE: Herein, the technical aspects of penile reconstruction and the outcomes in 17 children and adolescents treated for total or sub-total acquired penile loss are reported. MATERIAL AND METHODS: The median age at the time of injury was 3 months (range: 2 days-15 years). Twelve patients were born with normal penis but suffered injuries (11) or underwent surgical resection of the penis (1). The remaining 5, affected by bladder exstrophy (2) or cloacal exstrophy (3), had penile loss due to surgical complications. RESULTS: The median age at the time of surgery was 5 years (range: 2-20 years). The median length of the procedure was 5 h (range 4-8 h). Skin expander were inserted in preparation of phalloplasty in 9 patients. Corpora-cavernosa remnants were found and incorporated in the neophallus in 12 patients. In 7 patients, urethral remnants were also incorporated into the repair, placing the meatus at the tip of the neophallus. In the remaining patients the urethra was left in the acquired position after penile loss creating a perineal (2), scrotal (3), peno-scrotal (3), or posterior penile (1) urethrostomy. The first patient of this series was the only patient to receive simultaneously phalloplasty and total urethroplasty, with failure of urethral reconstruction. The median follow-up was 2 years (range 1-11 years). The overall complication rate was about 47%. All of the complications were late and required surgical revision. The results were assessed regarding overall functionality (voiding, erection/erogenous areas, masturbation/sexual intercourse) and aesthetic outcome using subjective and objective parameters. Psychological evaluation for both patient and parents was performed in 4 cases. DISCUSSION: There are no specific guidelines for treating significant penile injuries in the pediatric population. We do not think secondary severe penile impairments should wait until adult age for repair. In this specific subgroup of patients technical aspects differ from phalloplasty done for congenital aphallia, due to the possible presence of corpora-cavernosa/urethral remnants and the feasibility to perform a "functional phalloplasty" with very encouraging results. CONCLUSION: The De Castro's neo-phalloplasty remains one of the few techniques available for total penile reconstruction in pediatric age group. Data demonstrate that this technique for acquired aphallia is feasible and reproducible, however, it is a challenging procedure with a high complication rate and likelihood of revisions.

Brown Urology: A Historical Perspective.

The first Urology Residency Program in the United States was founded at the Johns Hopkins Hospital in the wake of the first structured surgery residency as established by Dr. William Halsted in the early 20th Century.1 Dr. Hugh Hampton Young was selected to lead the Genitourinary Division and the foundation for the first urology residency training program was established.2 The Brown University Medical School, initially opened in 1811, effectively closed circa 1827, and re-established in the 1970s, has a long tradition in training surgeons.3,4 The Rhode Island Hospital Urology Residency Training Program was organized in the early 1950s and will be explored in this article. Brown University affiliated with the residency program in the mid-1980s to establish the first and only academic urology residency program in Rhode Island. Today, this program provides state-of-the-art urologic care for thousands of patients in the state.
