Gubernaculum Testis and Cremasteric Vessel Preservation during Laparoscopic Orchiopexy for Intra-Abdominal Testes: Effect on Testicular Atrophy Rates.

J Urol 2019 02;201(2):378-385

Division of Pediatric Urology, Hospital for Sick Children, Toronto, Ontario, Canada.

Purpose: Gubernaculum sparing laparoscopic orchiopexy, which involves anatomical delivery of the testis through the internal inguinal ring, has been proposed as an alternative to conventional laparoscopic Fowler-Stephens orchiopexy, maximizing collateral blood supply and potentially decreasing atrophy rates. We compared the 2 techniques to test this hypothesis.

Materials And Methods: The primary (dependent) outcome of the study was rate of testicular atrophy, which was defined as palpation of a nubbin or inability to palpate a testis (complete atrophy) on postoperative physical examination at 3 and 12 months. Read More

Spectrum of Extratesticular and Testicular Pathologic Conditions at Scrotal MR Imaging.

Radiographics 2018 May-Jun;38(3):806-830

From the Department of Radiology and Imaging Sciences, Emory University School of Medicine, 1364 Clifton Rd NE, Atlanta, GA 30322 (P.K.M., D.A.B., P.A.H., J.P., C.C.M.); Department of Clinical Imaging, Hamad Medical Corporation, Doha, Qatar (A.S.A.); and Department of Radiology, Northwestern University Feinberg School of Medicine, Chicago, Ill (A.C., H.G., F.H.M.).

Diagnostic workup of scrotal lesions should begin with a complete clinical history and physical examination, including analysis of risk factors such as family history of testicular cancer, personal history of tumor in the contralateral testis, and cryptorchidism, followed by imaging. Scrotal ultrasonography (US) with a combination of gray-scale and color Doppler techniques has been the first-line imaging modality for evaluation of testicular and extratesticular lesions because of its low cost, wide availability, and high diagnostic accuracy. However, US has limitations related to operator dependence, the relatively small field of view, and lack of tissue characterization. Read More

Subphenotype meta-analysis of testicular cancer genome-wide association study data suggests a role for RBFOX family genes in cryptorchidism susceptibility.

Hum Reprod 2018 05;33(5):967-977

Nemours Biomedical Research/Alfred I. duPont Hospital for Children, Wilmington, DE, USA.

Study Question: Can subphenotype analysis of genome-wide association study (GWAS) data from subjects with testicular germ cell tumor (TGCT) provide insight into cryptorchidism (undescended testis, UDT) susceptibility?

Summary Answer: Suggestive intragenic GWAS signals common to UDT, TGCT case-case and TGCT case-control analyses occur in genes encoding RBFOX RNA-binding proteins (RBPs) and their neurodevelopmental targets.

What Is Known Already: UDT is a strong risk factor for TGCT, but while genetic risk factors for TGCT are well-known, genetic susceptibility to UDT is poorly understood and appears to be more complex.

Study Design, Size, Duration: We performed a secondary subphenotype analysis of existing GWAS data from the Testicular Cancer Consortium (TECAC) and compared these results with our previously published UDT GWAS data, and with data previously acquired from studies of the fetal rat gubernaculum.

Department of Pediatric urology, Nagoya City University Graduate School of Medical Sciences, 1 Kawasumi, Mizuho-cho, Mizuho-ku, Nagoya, Japan.

Background: Congenital anomalies of the kidney and urinary tract (CAKUT), such as renal dysplasia, hydronephrosis, or vesicoureteral reflux, are the most common causes of end-stage renal disease. However, the genetic etiology of CAKUT remains unclear. In this study, we performed whole exome sequencing (WES) to elucidate the genetic etiology of symptomatic CAKUT and CAKUT accompanied by cryptorchidism. Read More

Infrarenal high intra-abdominal testis: fusion of T2-weighted and diffusion-weighted magnetic resonance images and pathological findings.

BMC Urol 2017 Aug 24;17(1):66. Epub 2017 Aug 24.

Department of Urology, Fukushima Medical University School of Medicine, 1, Hikarigaoka, Fukushima, 960-1295, Japan.

Background: Several recent reports have demonstrated that the preoperative sensitivity and accuracy of identifying and locating non-palpable testes increases with the use of conventional MRI, in addition to diffusion-weighted imaging (DWI). Therefore, pre-operative prediction of the presence and location of testes using imaging techniques may guide management of intra-abdominal testis. Fowler-Stephens orchiopexy is effective for treating patients with intra-abdominal testis; however, long-term testicular function after this procedure has not been clarified. Read More

BMJ Case Rep 2017 Aug 8;2017. Epub 2017 Aug 8.

Department of Paediatric Surgery, Christian Medical College and Hospital Vellore, Vellore, Tamil Nadu, India.

We, herein, present a male neonate with an antenatally detected intra-abdominal cyst who presented at 18 days of life at which time, the ultrasound revealed a 5×4 cm cyst. Since he was asymptomatic, we planned to repeat the ultrasound a month later and operate if the cyst showed no regression. However, a week later, he presented with an acute abdomen, irritable cry and a repeat ultrasound showing a larger (8×6 cm) cystic mass with debris within. Read More

Point-of-Care Ultrasound Identification of an Abdominal Hernia.

Pediatr Emerg Care 2017 Aug;33(8):596-598

From the *Pediatric Emergency Medicine, Weill Cornell New York-Presbyterian Hospital, New York, NY; and †Emergency Medicine and ‡Pediatric Emergency Medicine, Yale University School of Medicine, New Haven, CT.

Pediatric emergency medicine physicians may be able to use point-of-care ultrasound (POCUS) as a tool to evaluate abdominal wall masses. We present a case of a 2-month-old infant with a lower abdominal mass identified as a hernia sac by POCUS. It was initially thought to represent a Spigelian-type abdominal wall hernia but subsequently determined to be an unusual presentation of an inguinal hernia with testicular entrapment. Read More

Blind ending vessels on diagnostic laparoscopy for nonpalpable testis: Is a nubbin present?

J Pediatr Urol 2017 Aug 15;13(4):392.e1-392.e6. Epub 2017 May 15.

Division of Urology, Ann and Robert H. Lurie Children's Hospital, Chicago, IL, USA.

Introduction: The traditional management paradigm for nonpalpable testis (NPT) has been that inguinal or scrotal exploration for a nubbin may be omitted when blind ending vessels are observed during diagnostic laparoscopy. Our aim was to examine whether blind ending vessels excluded the presence of a nubbin in a series of boys who underwent exploration in this setting.

Materials And Methods: Using a surgical database and chart review, pre-pubertal boys (≤12 years) with the diagnosis of undescended or atrophic testis who underwent a diagnostic laparoscopy for unilateral NPT between 2000 and 2015 were retrospectively identified. Read More
