Screening for undescended testis (UDT) in Japan is performed as a neonate, then at 1, 3, 10, and 18 months old, and 3 years old. Incidence of ascending testis (AT) after screening was reviewed....
All orchiopexy/orchiectomy at a single institute between July 2005 and June 2022 were reviewed retrospectively....
376 boys had 422 procedures; 54/422 (12.8%) were in 48 boys ≥ 4 years old (mean age: 6.7 years; range: 4-13); testes were normal (n = 22; 40.7%), small (n = 25; 46.2%), or atrophied (n = 7; 1.3%). The...
Comprehensive UDT screening probably contributed to the lower incidence of surgery and AT (especially AT + RET) in boys ≥ 4 years old....
In this report, we discuss the evaluation of a patient with chronic scrotal pain found to have a supernumerary testis (SNT), as well as a novel microsurgical approach to safely removing this testis....
To avoid any iatrogenic injury to the adjacent testis, we used an operating microscope to visualize the cord structures of both testes and carefully remove the smaller, atrophic, supernumerary testis....
This case demonstrates a novel microsurgical approach to excising a supernumerary testis that avoids injury to the blood supply, epididymis, and vas deferens associated with the normal testis....
Testis tumors are uncommon in oncology, and testicular metastasis from distant solid tumors are even rarer. We present two cases encountered in our department of pathology in CHU de Rennes, France. Mo...
The descent of the testis and the development of an inguinal hernia were the earliest published scientific work by John Hunter, the Scottish surgeon and anatomist who is acknowledged as the father of ...
The objective of our study is to examine the impact of monorchism on contralateral testicular size in children with non-palpable testis (NPT). Enhanced contralateral testicular volume or longitudinal ...
We analysed the records of 54 patients who underwent diagnostic laparoscopy for NPT between 2005 and 2020 in a European tertiary care centre. Testicular lengths (longitudinal diameter) and testicular ...
A total of 15 children presented with viable testes and 39 patients with testicular nubbin. Mean age was 20.5 months in the overall cohort and 22.6 vs 19.7 months in children with viable testis vs tes...
Patients with preoperative increased length and volume of the contralateral testis in the ultrasound examination are at significantly higher risk of monorchism than their counterparts with lower testi...
Perineal ectopic testis (PET) is a rare form of testicular migration abnormality. We report a case of neonatal PET diagnosis and early management. In reported cases, diagnosis is often late, well afte...
Contralateral Testis Hypertrophy (CTH) is a clinical marker that could be used to guide the choice of the main surgical strategy. In patients with a Non-palpable Testis (NPT), the degree of CTH as mea...
The purpose of this study was to establish the proper cut-off for identifying non-viable testes based on the current literature....
We systematically searched several medical databases as well as Google Scholar search engines for references and citations. All the studies that reported CTH as a result of NPT in prepubertal boys wer...
The current systematic review included 17 studies that assessed the cut-off point to detect non-viable testis. The size and length of the testes were taken into consideration based on our findings. We...
According to the results of our study, it seems that defining a cut point for diagnosis of CTH based on the size of the testis, cannot demonstrate the absence of a non-palpable testis....
MicroRNAs are involved in the regulation of spermatogenesis, are detected in semen and may be useful as molecular markers for predicting residual complete spermatogenesis in azoospermic men....
To study the biomarker potential of microRNAs that are detected in semen and testicular tissue....
MicroRNA profiles were analyzed in semen fractions of normozoospermic (n = 3) and azoospermic (n = 6) men by small RNA deep sequencing. Specific microRNAs were further analyzed by reverse transcriptio...
The sequenced microRNA profiles of semen supernatant fraction samples were distinct from the other fractions. Significant expression differences were observed between the semen supernatant of normozoo...
MicroRNA expression profiles in semen were distinguishable between azoospermic and normozoospermic men. The microRNA profile also diverged among azoospermic men subdivided according to their testicula...
The health risk of microplastics (MPs) is a growing global concern. Evidence of reproductive health damage caused by the accumulation of MPs in males is still lacking. In the present study, 6 testis a...
This study aimed to investigate the rate of re-ascent requiring re-operation after primary orchidopexy and to investigate eventual differences between the inguinal and scrotal approach as well as othe...
A retrospective cohort study of children treated for undescended testis (UDT) with orchidopexy between 2018 and 2022 was conducted. The primary outcome was re-ascent requiring re-operation, and the se...
A total of 662 testes in 554 patients were included. Re-operation occurred in 6% (7% with inguinal approach, 3% with scrotal approach, p = 0.04). Re-operation was associated with younger age, congenit...
The rate of re-ascent was 6% and the atrophy rate was 0.15%. A larger study may find predictors for re-ascent but with very low absolute risk. The lower rate of re-ascent with the scrotal approach is ...
