An epidemiologic study of penoscrotal transposition by maternal characteristics using data from the Texas birth defects registry.

BACKGROUND: Penoscrotal transposition (PST) is an uncommon urogenital malformation in which the penis is mal-positioned to be inferior to the scrotum. The purpose of this study was to explore PST risk by maternal characteristics and to describe co-occurring congenital abnormalities in the Texas Birth Defects Registry (TBDR). METHODS: We conducted a population-based descriptive study examining occurrence of PST in the TBDR between 1999 and 2019. The primary outcome variable was PST diagnosis during infancy. Descriptive variables included maternal age, education, and race/ethnicity. Prevalence ratios (PRs) were calculated within each maternal variable category using Poisson regression. Counts and percentages of cases with select co-occurring congenital abnormalities were also calculated. RESULTS: Overall, 251 infants had PST, providing a prevalence of 0.61/10,000 live male births (95% CI: 0.53-0.68). PST prevalence was significantly lower among infants of mothers who had lower educational attainment (high school), who were younger (<25 vs. 25-34), and who were Hispanic (vs. non-Hispanic White) and was significantly higher among older mothers (35+ vs. 25-39). Hypospadias was the most common co-occurring genitourinary anomaly, affecting close to 70% of cases. CONCLUSIONS: To our knowledge, this is the first investigation exploring the prevalence of PST in a population-based birth defects registry. Our findings help to understand the risk for PST among select maternal demographic characteristics and may assist in generating hypotheses about the underlying etiology of this condition for future work.

Abnormalities of the Scrotum and Testes.

Abnormalities of the bovine scrotum and testes are an important cause of infertility. Proper evaluation of the male reproductive system is a critical first step in screening for such abnormalities. Excessive periscrotal fat, cutaneous scrotal defects, and unilateral scrotal swelling are common deformities that warrant further investigation. Early diagnosis and surgical intervention are often needed to restore reproductive soundness. This article reviews these conditions and provides therapeutic modalities.

Unilateral Suprainguinal Ectopic Scrotum: Case Report and Literature Review.

Ectopic scrotum is an infrequent congenital scrotal anomaly. Different surgical methods of correcting ectopic scrotum have been used, but none have produced optimal cosmetic results for all types. We describe a case of left ectopic suprainguinal scrotum in a 14-month-old boy who had an undescended left testicle and a left-sided scrotal skin tag. Single-stage rotational flap scrotoplasty and unilateral orchiopexy were performed; however, we modified the surgical technique of scrotal rotation by excising the intervening longitudinal skin. Eight months after surgery, the repositioned scrotum had a better appearance, and the affected testicle was similar in size to the contralateral one. In comparison with other surgical methods, pedicle flap rotation of the ectopic scrotal skin with excision of the intervening longitudinal skin may produce a better cosmetic outcome.

[Effectiveness of penis up transfer method for penoscrotal transposition in children].

Objective: To investigate the effectiveness of penile up transfer method in the treatment of penoscrotal transposition (PST) in children. Methods: A clinical data of 46 children with PST admitted between January 2015 and March 2021 and met selective criteria was retrospectively analyzed. The M-shaped scrotal flap method was adopted in 21 cases (group A), and the penile up transfer method was adopted in 25 cases (group B). There was no significant difference in age and PST typing between the two groups ( t=0.491, P=0.626; χ 2=0.710, P=0.790). The operation time and postoperative complications of the two groups were recorded and compared, and the correction effect of PST was evaluated. Results: All operations were successfully completed, and no urethral injury occurred during operation. The operation time was significantly less in group B than in group A [(70.36±9.76) minutes vs. (96.62±13.18) minutes; t=7.553, P=0.000]. All children were followed up 6-33 months (mean, 13.2 months). There were 5 cases (23.8%) of skin necrosis and 6 cases (28.6%) of scar hyperplasia in group A, and 1 case (4.0%) of skin necrosis and 1 case (4.0%) of scar hyperplasia in group B. The incidence of complication was significantly lower in group B than in group A ( χ 2=3.949, P=0.047; χ 2=5.341, P=0.021). In the evaluation of PST correction at 6 months after operation, there were 15 cases of complete correction and 6 cases of incomplete correction in group A, 24 cases of complete correction and 1 case of incomplete correction in group B, and the difference was significant ( χ 2=5.341, P=0.021). Conclusion: The penis up transfer method is not only easy to correct PST, but also can correct scrotal separation at the same time, with fewer postoperative complications and satisfactory correction effect of penile scrotal appearance.

Pentaorchidism diagnosed on ultrasound examination: A case report and literature review.

Polyorchidism is a congenital malformation of the urogenital system that is usually found incidentally in adolescent age groups. Ultrasound and MRI are effective non-invasive diagnostic modalities which can differentiate this condition from other intrascrotal pathologies. Ultrasonography is mostly used in initial steps of diagnostic approach; however, MRI is considered as a modality to confirm diagnosis and evaluate possible malignancy. We report an extremely rare case of pentaorchidism (five testicles), presented with a left hemiscrotum mass. Diagnosis was made based on physical examination, laboratory analysis (testicular germ cell tumour markers and semen analysis) and imaging. Finally, close surveillance with ultrasound and physical examination was recommended for follow-up of this uncomplicated patient.

A Case of Scrotoschisis with Exteriorization of Both Testes.

Scrotoschisis is a congenital malformation characterized by testicular exstrophy through a scrotal defect.We report a full-term baby boy with exteriorization of both testes through a right parietal scrotal defect.Bilateral testes extrusion through a lateralized scrotoschisis can occur due to a scrotal septal defect.

Novel variants in KAT6B spectrum of disorders expand our knowledge of clinical manifestations and molecular mechanisms.

The phenotypic variability associated with pathogenic variants in Lysine Acetyltransferase 6B (KAT6B, a.k.a. MORF, MYST4) results in several interrelated syndromes including Say-Barber-Biesecker-Young-Simpson Syndrome and Genitopatellar Syndrome. Here we present 20 new cases representing 10 novel KAT6B variants. These patients exhibit a range of clinical phenotypes including intellectual disability, mobility and language difficulties, craniofacial dysmorphology, and skeletal anomalies. Given the range of features previously described for KAT6B-related syndromes, we have identified additional phenotypes including concern for keratoconus, sensitivity to light or noise, recurring infections, and fractures in greater numbers than previously reported. We surveyed clinicians to qualitatively assess the ways families engage with genetic counselors upon diagnosis. We found that 56% (10/18) of individuals receive diagnoses before the age of 2 years (median age = 1.96 years), making it challenging to address future complications with limited accessible information and vast phenotypic severity. We used CRISPR to introduce truncating variants into the KAT6B gene in model cell lines and performed chromatin accessibility and transcriptome sequencing to identify key dysregulated pathways. This study expands the clinical spectrum and addresses the challenges to management and genetic counseling for patients with KAT6B-related disorders.

Bladder Agenesis and Bilateral Ectopic Ureters in an Infant Male With Cystic Renal Dysplasia, Imperforate Anus, and Penoscrotal Transposition.

Bladder agenesis is a rare congenital anomaly infrequently reported in the literature, with an incidence of 1/600,000 patients.1 Commonly associated with other fatal malformations, the condition is often incompatible with life.2 Prior reports estimate that over 90% of living children born with this malformation are female, owing to renal preservation resulting from low pressure drainage of urine into the vagina, uterus, and vestibule.3,4 Herein we report a rare case of an infant male born with penoscrotal transposition and end stage renal disease secondary to bilateral cystic renal dysplasia found to have concurrent bladder agenesis and bilateral ureteral ectopia.

Megaprepuce: A New Surgical Technique with Excellent Cosmetic and Functional Results.

Background: Congenital megaprepuce (CMP) is a malformation consisting of redundant inner foreskin, normal penile shaft, and severe phimosis. The excess inner prepuce pushes the penile shaft deeper causing the appearance of a buried penis. We describe a novel surgical technique using dartos fascial flaps to reconstruct the prepuce giving excellent cosmetic and functional results. Patients and Methods: Penile reconstruction was performed by a single surgeon in 07 cases of CMP between January 2018 and December 2019. In all cases, the described surgical technique was used. Following surgery, cosmetic and functional outcomes were reviewed as well as the incidence of complications. The patients' ages ranged from 15 to 27 months (mean = 19). Mean hospital stay was 9 hours (range = 7-12). Operating time was between 50 and 85 minutes. Results: Postoperative appearance of the penis was satisfactory for all the parents in our group. Swelling of the penile shaft was seen in all of our patients but settled within one week of surgery. Scrotal hematoma was seen in only one of our patients, but that also did not need any intervention and settled spontaneously. During the follow-up period (mean = 14.5 months, range 6-24) no patient underwent revision surgery. In all our patients, the final appearance was of a circumcised penis. The final similarity to a normal circumcised penis was excellent in all of our patients. Correction of penoscrotal transposition was done in all patients achieving an elongated penile shaft and almost invisible postoperative scarring. Conclusion: Our modified surgical procedure to correct CMP is a safe and simple technique, providing good cosmetic results with the appearance of a standard circumcised penis. This also provides a good functional outcome with complication rate quite low. This technique is also easy to reproduce and teach compared with other complex procedures.

Atypical rectoscrotal and rectoperineal fistula in male anorectal malformations: a case series of non-detaching strategies for preventing urethral injury.

Anorectal malformations (ARM) represent a broad spectrum of patients with different level of the rectum and type of a fistula. Standardized approaches are usually successful, but patients occasionally present with an unusual course of fistula which requires a modified surgical strategy. We present here three male ARM patients with an atypical fistula which did not have connection with the urinary tract, but ran near the fistula. Case 1 has a low-type ARM with a rectoscrotal fistula running deep and partly involved in the corpus spongiosum. Anorectoplasty was performed through an anterior sagittal incision and the anterior wall of the fistula was laid open leaving the posterior wall undetached. Case 2 was diagnosed with an intermediate-type ARM with a long rectoscrotal fistula running near and parallel the urethra. Posterior sagittal anorectoplasty (PSARP) was performed leaving the fistula untouched. Case 3 presented with an intermediate-type ARM with a rectoperineal fistula adherent to the urethra. The patient was treated by PSARP leaving the fistula and part of the muscle coat of the rectum in situ. All the cases were smoothly discharged and no urological complication nor problem associated with the residual fistula was observed at the latest follow-up (17 months-2 years). Preoperative distal colostography with the aid of diverting colostomy was importantly useful for deciding surgical procedure.

Prenatal diagnosis of complete penoscrotal transposition with normal scrotum: Two case reports and review of the literature.

Complete penoscrotal transposition is an extremely rare congenital anomaly and is usually associated with other urinary system abnormalities. Prenatal diagnosis is feasible by demonstrating perineal anatomy and its relation with scrotum and phallus. We describe two prenatal cases presenting with oligohydramniosis and megacystis due to lower urinary tract obstruction. Postnatal diagnosis was confirmed in both cases. Considering the dismal perinatal outcome, an accurate prenatal diagnosis is required for counseling the parents and preparing for postnatal care.

Accessory Scrotum.

Introduction: An accessory scrotum is characterized by a characteristic skin appearance in addition to a normal scrotum in the anatomically normal position. Case report: We report an accessory inguinal left hemiscrotum in a 15-day-old male infant. There was a normal scrotum and penis. The testes were descended and normally located within the normal scrotum. Additional scrotal skin was located anterior and lateral to the normal scrotum. Conclusion: The accessory ectopic scrotum is readily observed by physical examination. Cosmetic excision is the treatment of choice.

The International Pediatric Endosurgery Group Evidence-Based Guideline on Minimal Access Approaches to the Operative Management of Inguinal Hernia in Children.

Introduction: Minimally invasive surgery (MIS) for inguinal hernia repair (IHR) in children has been reported for more than two decades. The International Pediatric Endosurgery Group (IPEG) Evidence-Based Review Committee chose MIS IHR as the inaugural topic for review and presentation at the 2016 IPEG annual meeting. Materials and Methods: English language articles published between January 1, 2009, and December 31, 2015, were reviewed and included in this evidence-based review after searching PubMed, Cochrane Reviews, ClinicalTrials.gov, Google Scholar, and EMBASE. Results: Level 1a and 1b evidence supports the recommendations that operative time for bilateral IHRs should be considered shorter and postoperative complications rates should be considered lower in MIS repair over open. Recurrence rates are similar between the two methods (level 1a and 1b evidence). No level 1 evidence exists to support one MIS technique over another or that operating on a detected contralateral patent processus vaginalis during laparoscopy makes any difference in long-term outcome to the patient. Conclusions: The advantages of lower postoperative complications and shorter operative times have been found in studies of surgeons experienced in MIS repair and differences were small. The evidence in this review supports that MIS repair is a safe, effective method of IHR with proper training and mentorship.
