Since ectopic twisted testes are a rare condition, correctly and opportunely diagnosing them preoperatively is difficult and can result in testicular necrosis. We report a clinical case of a twisted ectopic testis that was diagnosed preoperatively by ultrasonography, and the testis could be rescued. A generally healthy 13-year-old boy was referred to our Urology Department after experiencing a painless swelling in the left inguinal region two weeks before, and mild exercise-induced pain in the same area one week before the referral. The mild pain persisted without worsening. On examination, a mildly tender swelling was present in the left inguinal region. The left half of the scrotum was empty; however, the right testis was normal in size and position. Ultrasonography revealed that the left spermatic cord was present within the inguinal canal and was directed superficially, with spiral twisting. The left testis was located above the inguinal canal, with normal echogenicity, but was smaller than the right normal testis (right testis, 41 × 28 × 16 mm; left testis, 18 × 18 × 8 mm). Power Doppler ultrasound showed normal blood flow in the left testis. Consequently, we diagnosed an ectopic testis with torsion. Intraoperative examinations confirmed the presence of the testis in the left superficial inguinal pouch. Although the testis had twisted five and a half turns (1980°) clockwise at the level of the superficial inguinal pouch, ischemia was not evident. Orchidopexy of both testes was performed, and the left testicular size was maintained after surgery. If swelling is present in the inguinal region and no testis is found in the scrotum, an ectopic testis should be considered in the differential diagnosis. Preoperatively diagnosing an ectopic, twisted testis by ultrasonography alone is difficult. However, we used ultrasonography effectively to diagnose the ectopic testis preoperatively by tracking the spermatic cord and confirming the torsion of the testis.

Background There are limited studies on the necessity of preoperative antibiotics in surgeries for undescended testis (UDT), inguinal hernia (IH), and umbilical hernia (UH) in children. Here, we investigated the relationship between preoperative antibiotic use and surgical site infection (SSI) incidence in surgeries for UDT, IH, and UH in children. Methods Patients who underwent surgery for IH were subdivided based on the surgical form into those who underwent (i) open IH (OIH) repair and (ii) laparoscopic percutaneous extraperitoneal closure (LPEC). Medical records of patients who underwent surgeries for UDT and IH or UH were retrospectively examined. The SSI incidence was compared between patients receiving and not receiving preoperative antibiotics. In patients who underwent surgery for UH or LPEC, the relative risk of SSI postoperatively in the inguinal region (including surgery for UDT and OIH repair) was examined. Results In total, 926 patients with 1389 wounds were included in this study. SSI rates in patients who underwent surgeries for UDT and UH, OIH repair, and LPEC were 0.2% and 2.7%, 0.3%, and 0.4%, respectively. These rates were not significantly different between patients receiving and not receiving preoperative antibiotics. In patients who underwent surgery for UH, the relative risk of SSI was statistically significant at 9.8 compared with that in patients who underwent surgeries in the inguinal region (95% CI = 1.3-74; p = 0.013). Conclusions Preoperative antibiotics are unnecessary in surgeries for UDT and OIH repair. Patients undergoing surgery for UH should be given extensive care as they are at a high risk of SSI.

Undescended testis (UDT, cryptorchidism) is the most frequent genital anomaly in boys. However, its treatment varies widely throughout the world. This second part of our roundtable discussion aims to continue to ask global experts to express their attitudes towards several case scenarios of UDT in order to explore the rationale for their clinical decisions. As the European Association of Urology - Young Academic Urologists Pediatric Urology Working Group, we believe that this roundtable series will facilitate colleagues all over the world to reflect and improve their practices regarding the treatment of UDT.

OBJECTIVE: Previous studies showed that extra blood supply can decrease testicular atrophy following laparoscopic orchiopexy. We evaluated the impact of preserving the gubernacular attachment (which contains blood supply from cremasteric artery and its anastomoses) on atrophy rates following open conventional orchiopexy.
METHODS: This double-blinded randomized trial was implemented from March 2022 to September 2023. Included boys with non-palpable testis, even with examination under anesthesia, underwent diagnostic laparoscopy to evaluate the testis\'s location and size. Nubbin testes and those with > 2-cm distance from the internal inguinal ring. Participants were assigned into two groups (gubernaculum sparing (GS) and excision (GE)) by permuted block randomization. Overall success was defined as achieving both morphologic success (atrophy <20% of the intraoperative size) and anatomical success (scrotal or high-scrotal locations). Boys were followed at three- and six-month post-surgery via ultrasound. Independent t-test, repeated ANOVA, and Friedman\'s tests were used where appropriate.
RESULTS: Of 92 boys (105 UDTs overall), 75 testes (36 in GS, 39 in GE groups) were used in the analysis. The mean age of participants was 25 ± 17 months (range 6-84). The mean testis size of cases intraoperatively was 460 ± 226, 396 ± 166, and 520 ± 258 mm3 among all participants, GS, and GE cases, respectively. Both groups showed a significant decrease in testicular volume on both follow-up checkpoints, but this decrement was significantly higher in the GE group (p < 0.001). The anatomical success rate was significantly higher among GS boys (97.2% versus 82.1%; p = 0.038). The overall success rate was significantly higher for the GS group (61.1% versus 25.6%; p = 0.002).
CONCLUSIONS: Although mean testicular volume decreased in both groups, we found superior morphologic and overall success rates among the GS group. The greatest size reduction was noted at the three-month post-surgery compared to the six-month checkpoint.

Undescended testis is the most common genital disorder identified at birth. Boys who do not have spontaneous descent of the testis at 6 months of age, adjusted for gestational age, should be referred to pediatric urology for timely orchiopexy. Retractile testes are at risk for secondary ascent of the testes and should be monitored by physical examination annually. If there is concern for ascent of the testis, pediatric urology referral is recommended. Most cases of phimosis can be managed medically with topical corticosteroids and manual retraction of the foreskin.

BACKGROUND: The last decades revealed new scientific knowledge regarding the fertility and potential malignancy of undescended testis AQ2(UDT). Accordingly, many guidelines changed their recommendation concerning timing of therapy, with the goal of an earlier time of surgery.
METHODS: We analyzed the number of new diagnosis and performed surgeries in predefined age groups provided by the obligatory annual reports of German hospitals in the reimbursement.INFO\"-tool between 2006 and 2020.
RESULTS: Overall, 124,741 cases were analyzed. We showed a slight increase in performed surgeries in the first year by 2% per year with a main increase till 2011, a constant number of surgeries between first and 4th year and a decrease of surgeries between 5 and 14th year of living with a main decrease till 2009 by 3% per year.
CONCLUSIONS: Even if our results illustrate an increasing adaption of the guideline\'s recommendation, there is still a significant number of patients who receive later treatment. More research about the reasons and circumstances for the latter is needed.

Background Undescended testis is a common pediatric surgical presentation condition with potential long-term consequences if left untreated. It is characterized by the failure of one or both testes to descend into the scrotum. This study aims to measure and enhance awareness and knowledge about undescended testis through comprehensive medical research and provide evidence-based recommendations. Objective The objective of this study was to evaluate participants\' knowledge regarding undescended testes and assess the level of interest and awareness among individuals and parents about the importance of early examination and treatment. Methods It is a cross-sectional, nationwide study targeting the population of Al-Qunfudhah. The study was conducted in December 2023 using a validated questionnaire distributed through social media platforms. Results The study analyzed data from 459 participants to assess their knowledge and attitudes regarding undescended testis. Participants\' knowledge was evaluated. In general, the mean ± SD score of knowledge was 3.61 ± 2.33. Higher education level, occupation, and having children were associated with greater knowledge. Attitudes were measured. The mean attitudes score was 2.37 ± 1.58. Higher education level, occupation, and marital status influenced attitudes. Conclusion This study provides valuable insights into the knowledge and attitudes of individuals regarding undescended testis. Participants displayed moderate levels of knowledge and positive attitudes, with educational attainment and occupation playing significant roles. These findings highlight the importance of targeted educational interventions to improve awareness and promote positive attitudes toward undescended testis.

BACKGROUND: Congenital inguinal hernia, hydrocele and undescended testis (UDT) are associated with patent processus vaginalis. The smooth muscles present in the processus vaginalis aid in the descent of the testis and undergo programmed cell death after testicular descent leading to obliteration. The persisting amount of smooth muscle in the processus vaginalis influences the clinical outcome as inguinal hernia, hydrocele or UDT. Therefore, a study was conducted to evaluate the processus vaginalis in these three conditions to observe the presence and phenotype of smooth muscle cells and the presence of myofibroblasts.
METHODS: The processus vaginalis sacs in patients with inguinal hernia, hydrocele and UDT were examined using light microscopy for the presence and distribution of smooth muscle cells and immunohistochemical staining for vimentin, desmin, and α-smooth muscle actin (SMA) to identify the smooth muscle phenotype. Transmission electron microscopy was also performed in all the sacs to observe the presence of myofibroblasts.
RESULTS: Seventy-eight specimens of processus vaginalis (from seventy-four patients), distributed as 47%, 27%, and 26% as inguinal hernia, hydrocele and UDT respectively, were included in the study. The sacs from inguinal hernia and hydrocele had significantly more presence of smooth muscles distributed as multiple smooth muscle bundles (p < 0.001). Desmin and SMA staining of smooth muscle cells was observed in significantly more sacs from hydrocele, followed by inguinal hernia and UDT (p < 0.001). The sacs from UDT had a significant presence of striated muscles (p = 0.028). The sacs from inguinal hernia had a significant presence of myofibroblasts, followed by hydrocele and UDT (p < 0.001) and this significantly correlated with the light microscopy and immunohistochemical features. The processus vaginalis sacs from four female patients did not differ statistically from the male inguinal hernia sacs in any of the above parameters.
CONCLUSIONS: The processus vaginalis sacs in pediatric inguinal hernia, hydrocele and undescended testis differ in the presence, distribution and phenotype of smooth muscles and the presence of myofibroblasts. The clinical presentations in these entities reflect these differences.

Undescended testis (UDT), known as cryptorchidism (CRY), is a common congenital disorder in which one or both testicles do not descend normally into the scrotum. A unilateral UDT model was established by inducing UDT in mice through surgery. The results showed that the testis in the UDT model group was abnormal; the lumen of the seminiferous tubule was atrophic; apoptosis, necrosis and shedding were observed in many of the germ cells; the level of sex hormones was abnormal; and mature sperm was reduced. Subsequently, transcriptome sequencing was conducted on the testicular tissue of UDT model mice. Through analysis and verification of differential genes, AZIN2 was identified as playing a key role in the decline in male fertility caused by cryptorchidism. AZIN2 expression and spermine content was down-regulated in the testis of the UDT group. We then used a combination of hypoxanthine and xanthine to create a GC-1 cell damage model. In this model, AZIN2 expression and spermine content was down-regulated. When si-Azin2 transfected GC-1 cells, cell viability and proliferation were decreased. However, in the GC-1 cell damage model transfected with Azin2 over-expressed plasmid, AZIN2 expression and spermine content was up-regulated, reversing the cell damage caused by hypoxanthine and xanthine, and restoring the proliferation ability of GC-1 cells. These results indicate that in UDT, down-regulated AZIN2 expression is a factor in testicular damage. This discussion of the connection between AZIN2 and germ cells has important clinical significance as it provides an important reference for the diagnosis and treatment of cryptorchidism.

UNASSIGNED: Sexual dysfunction is highly prevalent among men of reproductive age. Clinical practice guidelines have been established to assist providers in identification and education of patients who are at increased risk for infertility and sexual dysfunction with certain congenital and acquired urogenital disorders. The authors sought to review the reproductive and sexual health implications of treating common childhood urological conditions with commonly performed surgical procedures.
UNASSIGNED: To ensure the inclusion of influential and highly regarded research, we prioritized citations from the most-frequently cited articles on our respective review topics. Our inclusion criteria considered studies with substantial sample sizes and rigorously designed methodologies. Several topics were reviewed, including penile chordee, hypospadias, posterior urethral valves, varicoceles, undescended testicles, and testicular torsion.
UNASSIGNED: For chordee, surgical plication or corporal grafting may be employed. Erectile function remains unaltered post-surgery, while penile length may decrease after repair, which may be avoided using dermal grafts. Hypospadias repair hinges on severity and availability of the urethral plate. Those who underwent hypospadias repair report decreased penile length, but sexual satisfaction, libido, and semen quality are comparable to controls. Posterior urethral valves are usually treated with valve ablation. While valve ablation and bladder neck incision have not been found to affect ejaculatory function, high degree of concurrent renal dysfunction related to nephrogenic and bladder dysfunction may impact semen parameters and erectile function. Regarding varicocele, earlier management has been associated with better long-term fertility outcomes, and surgical intervention is advisable if there is observable testicular atrophy. Earlier repair of undescended testicle with orchiopexy has been found to improve fertility rates as well as decrease malignancy rates. Unilateral orchiectomy for testicular torsion without the ability for salvage has been shown to have decreased semen parameters but unaffected fertility rates.
UNASSIGNED: Infertility and sexual dysfunction are multivariable entities, with etiologies both congenital and acquired. At the same time, many common pediatric urology surgeries are performed to correct anatomic pathology that may lead to reproductive dysfunction in adulthood. This review highlights the need for diagnosis and management of pediatric urologic conditions as these conditions may impact long-term sexual function post-operatively.
Long-term impact of commonly performed operations in pediatric urology on sexual health Many men of reproductive age face sexual health challenges, prompting the creation of guidelines for identifying and addressing issues related to urogenital disorders. This study explores the impacts of common surgical procedures on reproductive and sexual health in children with urological conditions. By reviewing extensive literature, the study focuses on the long-term effects of pediatric urologic surgeries, emphasizing influential and frequently cited research for a comprehensive understanding. For conditions like chordee, surgical options such as plication or grafting may be considered. While erectile function typically remains unchanged, there might be a decrease in penile length post-surgery, which can be addressed with specific techniques. Hypospadias repair varies based on severity, with those undergoing the procedure having shorter penises. However, their sexual satisfaction, libido, and semen quality are comparable to others. Treatment of posterior urethral valves (PUV) often involves valve ablation, however some studies have shown altered semen parameters following ablation. Managing varicocele early on leads to better outcomes, and surgery is recommended if testicular atrophy is observed. Orchiopexy and orchiectomy are procedures for undescended testis (UDT) and testicular torsion in children. Pediatric urologic diseases and their surgical interventions can significantly affect sexual function and fertility in adulthood due to their multifactorial nature. While some procedures aim to preserve or enhance sexual potential such as proper urethral development, others may inadvertently impact sexual health negatively, such as necrotic testes removal. This underscores the importance of thorough diagnosis and management of pediatric urologic conditions to safeguard long-term sexual function post-surgery.
