RESUMO
Acquired undescended testes were once considered a sporadic disease. In recent years, reports suggest that they are not uncommon, with an incidence rate about 3 times that of congenital undescended testes. The etiology of acquired undescended testes remains inconclusive, clinical diagnostic standards are unclear, and treatment approaches are still controversial. There is ongoing debate about the mechanism of testicular ascent. The prevailing view is that acquired undescended testes occur due to the partial absorption of the gubernaculum, which forms part of the parietal peritoneum. The residual gubernacular fibers continuously pull on the spermatic cord, preventing the spermatic cord from elongating proportionately to somatic growth, leading to a re-ascent of the testis. Acquired undescended testes may increase the risk of testicular cancer, but this is still debated. The preferred treatment method is also controversial. However, surgical fixation has an immediate effect; no studies have proven that early surgery improves fertility in patients. The etiology of acquired undescended testes is closely related to the continuous pull of the residual gubernacular fibers on the spermatic cord, which prevents the cord from extending proportionately to body growth. There are no clear diagnostic standards for acquired undescended testes yet, and spontaneous descent is possible, so testicular fixation surgery may not be the preferred treatment method.

PMDS (persistent Müllerian duct syndrome) is a rare disorder of sex development characterised by the presence of Müllerian duct remnants in a phenotypically male individual with a 46XY karyotype. Radiological investigations play a crucial role in diagnosing and characterising this condition. Ultrasound and MRI are the modalities of choice. They help to non-invasively localise the gonads and Müllerian duct derivatives. Broadly, PMDS has two anatomical variants: male type and female type. The case report presented here does not fit into these classically described variants and can be called a variant of the female type. There is a risk of infertility and malignant transformation of undescended testis and Müllerian duct derivatives in cases of PMDS. Hence, management is focused on preventing these risks. Surgical intervention involves orchidopexy, removal of Müllerian duct derivatives and inguinal hernia repair.

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. CONCLUSION: 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.

Hyperbaric oxygen treatment (HBOT) can be utilised for necrotising soft tissue infections, clostridial myonecrosis (gas gangrene), crush injuries, acute traumatic ischaemia, delayed wound healing, and compromised skin grafts. Our case was a 17-month-old male patient with Noonan syndrome, idiopathic thrombocytopenic purpura, and bilateral undescended testicles. Haematoma and oedema developed in the scrotum and penis the day after bilateral orchiopexy and circumcision. Ischaemic appearances were observed on the penile and scrotal skin on the second postoperative day. Enoxaparin sodium and fresh frozen plasma were started on the recommendation of haematology. Hyperbaric oxygen treatment was initiated considering the possibility of tissue necrosis. We observed rapid healing within five days. We present this case to emphasise that HBOT may be considered as an additional treatment option in patients with similar conditions. To our knowledge, no similar cases have been reported in the literature.

AIM: To assess testicular volume at puberty for boys who underwent orchidopexy at 9 or at 36 months compared to boys with spontaneous postnatal descent. METHODS: At age 6 months, boys with congenital unilateral cryptorchidism were randomised to surgery at 9 or 39 months of age and followed to 16 years in parallel with boys with spontaneous postnatal descent. Ultrasound was done at 11 and 16 years to determine testicular volume. The ratio of the initially undescended testis to its scrotal counterpart was used to assess testicular growth. RESULTS: At age 16, the ratio was lower (p < 0.00) in the late group compared to the early group. At 16 years, the spontaneously descended testes were significantly smaller than their scrotal counterparts but larger than the operated groups (early p < 0.01 and late p < 0.00). CONCLUSION: Our data at 16 years show that orchidopexy at 9 months results in better testicular growth compared to 3 years but did not reach the corresponding volumes of their scrotal counterparts. This indicates that earlier surgery is beneficial to testicular growth. At age 16, the postnatally descended testes were not only larger than the surgically treated testes but also exhibited impaired testicular growth.

PURPOSE: 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 other potential predictors for re-ascent. METHODS: 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 secondary outcome was atrophy rate. Independent variables were age, underlying conditions, side, surgical approach, operation time, bilaterality, congenital/ascended UDT, presence of scrotal hypoplasia, presence of a patent processus vaginalis, division of external oblique, and suture of the testis. Univariate and logistic regression were used to evaluate differences between groups and risk for re-ascent. RESULTS: 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, congenital UDT, and inguinal approach, but neither of these variables remained significant in multivariate analyses. Atrophy occurred in one testis. CONCLUSION: 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 probably due to selection bias.

BACKGROUND: Suspicion of testicular torsion represents a urological emergency, necessitating immediate surgery. Comprehensive data on the current trends and perioperative outcomes regarding surgical exploration are sparse. Therefore, we utilized nationwide data on the prevalence and results of this surgery, aiming to provide evidence on this matter. METHODS: We assessed the GeRmAn Nationwide inpatient Data (GRAND) from 2005 to 2021, provided by the Research Data Center of the Federal Bureau of Statistics. We performed multiple regression analyses to evaluate the perioperative outcomes (length of hospital stay, transfusion, and surgical wound infection) after surgical exploration due to suspected testicular torsion based on both the outcome of surgery (orchiectomy, detorsion with preservation of the testicle, and no testicular torsion) and on the department of operation (urological versus non-urological). RESULTS: A total of 81,899 males underwent surgical exploration due to suspected testicular torsion in Germany from 2005 to 2021. Of them, 11,725 (14%) underwent orchiectomy, 30,765 (38%) detorsion with preservation of the testicle and subsequent orchidopexy, and 39,409 (48%) presented no testicular torsion. Orchiectomy was significantly associated with longer length of hospital stay (day difference of 1.4 days, 95%CI: 1.3-1.4, p < 0.001), higher odds of transfusion (1.8, 95% CI: 1.2-2.6, p = 0.002) and surgical wound infections (1.8, 95%CI: 1.4-2.3, p < 0.001) compared to no testicular torsion. The proportion of patients undergoing orchiectomy was significantly lower in urological departments (14%) versus non-urological departments (16%) and the proportion of patients undergoing preservation of testicle after detorsion was significantly higher in urological departments (38%) versus non-urological departments (37%), p < 0.001. Patients undergoing treatment in a urological department were discharged earlier and presented lower odds of transfusion and surgical wound infection (p < 0.001) compared to patients undergoing treatment in a non-urological department. CONCLUSIONS: Nearly half of patients who underwent surgery for suspected testicular torsion did not have intraoperatively the condition confirmed. Patients treated in urological departments had significantly better perioperative outcomes compared to those treated in non-urological departments. Therefore, we advise to refer patients to urological treatment as early as possible.

Manual detorsion is infrequently performed in pediatric emergency medicine, particularly in centers with urology coverage. In no other emergency condition does an emergency physician not take immediate action to alleviate pain and damage, even if definitive care is close by. A small number of case reports exist in which pediatric emergency physicians have performed manual detorsion. This review the literature presents the case for routine manual detorsion prior to definitive orchiopexy.

INTRODUCTION: Scrotal and inguinal orchiopexy are two commonly used surgical approaches for palpable undescended testis (UDT), each with distinct advantages. However, the optimal approach remains a matter of debate, warranting a comprehensive meta-analysis of randomized controlled trials (RCTs) to guide clinical decision-making. MATERIALS AND METHODS: A comprehensive literature search was conducted, adhering to PRISMA guidelines, to select RCTs comparing scrotal and inguinal orchiopexy for palpable UDT. Eight RCTs were selected for meta-analysis. Outcome measures included operative time, hospitalization duration, total complications, wound infection or dehiscence, testicular atrophy or hypotrophy, and testicular re-ascent rate. The evaluation of the study's quality was conducted by utilizing the revised Cochrane risk-of-bias tool. RESULTS: Scrotal orchiopexy showed significantly shorter operative time compared to the inguinal approach (WMD: - 15.06 min; 95% CI: - 21.04 to - 9.08). However, there was no significant difference in hospitalization duration (WMD: - 0.72 days; 95% CI: - 1.89-0.45), total complications (OR: 1.08; 95% CI: 0.70-1.66), wound infection or dehiscence (OR: 0.73; 95% CI: 0.27-1.99), testicular atrophy or hypotrophy (OR: 1.03; 95% CI: 0.38-2.78), and testicular re-ascent (OR: 1.43; 95% CI: 0.67-3.06) between the two approaches. A small proportion of cases (7.3%) required conversion from scrotal to inguinal orchiopexy due to specific anatomical challenges. CONCLUSION: Both scrotal and inguinal orchiopexy are safe and effective for palpable UDT, with comparable outcomes in terms of hospitalization and complications. Scrotal orchiopexy offers the advantage of shorter operative time. Clinicians can use this evidence to make informed decisions on the surgical approach for palpable UDT.

Transverse testicular ectopia (TTE) is a rare congenital malformation where both testes descend through the same inguinal canal and are located in the same hemiscrotum. It is usually treated with transseptal orchiopexy. In this article, we report the case of a 1-year-old boy diagnosed with TTE who was successfully treated with laparoscopically assisted orchiopexy by going through the anatomical conventional route. A four-month-old boy was referred to our department with bilateral empty scrotum. On the physical examination, the left testis was palpable in the left groin region and the right testis was impalpable. A follow up ultrasonography was performed after 4 months, and an oval-shaped testis-like structure was detected in left internal inguinal ring near the left testis. Right side TTE was suspected in the initial diagnosis. Laparoscopic surgery was performed at age one. The left testis was observed in the inguinal canal, and the right testis was ectopically located in the left opening inguinal canal above the left testis. Two spermatic cord and testes were separated respectively, and the right testis was pulled into abdominal space laparoscopically and brought down to the right hemiscrotum via the right inguinoscrotal canal. Bilateral orchiopexy was performed via the normal anatomical route. The postoperative course was uneventful, and testes were in the scrotum bilaterally one year after orchiopexy.

Extravaginal torsion (EVT) is a rare type of testicular torsion that usually occurs in neonates. The primary type of testicular torsion that occurs in adolescents is intravaginal torsion. In this case report, we describe the first case of EVT reported in a 16-year-old male with a contralateral bell clapper deformity and subsequent surgical management using a tunica vaginalis flap and bilateral orchiopexy. In discussion of this case, we examine possible anatomical causes of EVT and suggestions for appropriate surgical management.

Introduction: Cryptorchidism is a common genital disorder. Approximately 20% of azoospermic or infertile men reported having histories of cryptorchidism. Bilateral cryptorchidism may have been more condemned than unilateral cryptorchidism. Early treatment by orchidopexy is the definitive procedure for cryptorchid patients with cryptorchidism. However, fertility potency after orchidopexy may be adversely affected and assisted reproduction techniques will be required for infertile patients. Objective: To compare the reproductive outcomes between unilateral and bilateral orchidopexy groups. Methods: A retrospective cohort study at a tertiary hospital, including a total of 99 infertile men who underwent orchidopexy to treat cryptorchidism and subsequently underwent their first IVF/ICSI-ET cycle. Men were grouped according to the laterality of their cryptorchidism and orchidopexy surgeries they received. Fertilization rate and live birth rate were chosen as parameters for evaluating outcomes. Results: The sperm concentration and viability were significantly higher in unilateral orchidopexy group than in bilateral orchidopexy group (28.09 ± 27.99 vs 7.99 ± 14.68, P=0.001; 33.34 ± 22.52 vs 11.95 ± 17.85, P=0.001). Unilateral orchidopexy group showed lower demand for ICSI (66.07% vs 95.35%, P<0.001). Interestingly, both groups exhibited similar rates of fertilization, clinical pregnancy, live birth and birth defect. Boy birth ratio was lower in bilateral orchidopexy group as compared to unilateral orchidopexy group (27.27% vs 58.62%, P=0.026). Conclusion: A history of bilateral orchidopexy surgery correlates with a worsened sperm parameter and a higher demand for ICSI as compared to patients with history of unilateral orchidopexy. However, this does not influence the final live birth rate.

BACKGROUND: To lower the risk of testicular malignancies and subfertility, international guidelines recommend orchidopexy for undescended testis (UDT) before the age of 12-18 months. Previous studies reported low rates of 5-15% of timely surgery. Most of these studies are based on DRG and OPS code-based data from healthcare system institutions that do not distinguish between congenital and acquired UDT. METHODS: In a retrospective study data of all boys who underwent orchidopexy in a university hospital and two outpatient surgical departments from 2009 to 2022 were analyzed. The data differentiates congenital from acquired UDT. RESULTS: Out of 2694 patients, 1843 (68.4%) had congenital and 851 (31.6%) had acquired UDT. In 24.9% of congenital cases surgery was performed before the age of 12 months. The median age at surgery for congenital UDT was 16 months (range 7-202). Over the years there was an increased rate of boys operated on before the age of 2 (40% in 2009, 60% in 2022). The median age fluctuated over the years between 21 and 11 months without a trend to younger ages.. The covid pandemic did not lead to an increase of the median age at surgery. The median time between referral and surgery was 46 days (range 1-1836). Reasons for surgery after 12 months of age were a delayed referral to pediatric surgeries (51.2%), followed by relevant comorbidities (28.2%). CONCLUSION: Compared to recent literature, out data show that a closer look at details enables a more realistic approach. Still, there is no trend towards the recommended age for surgical treatment observable, but the rate of timely operated boys with congenital UDT is significantly higher than stated in literature.

OBJECTIVES: This study aimed to establish a nomogram for predicting the probability of testicular salvage after testicular torsion in children. METHODS: We retrospectively collected data of children with testicular torsion who were treated at Shenzhen Children's Hospital between September 2005 and August 2022. Of the training cohort, 113 patients who underwent orchiectomy and five with testicular atrophy after orchiopexy were included in the failed testicular salvage group. Additionally, 37 patients who underwent orchiopexy without postoperative testicular atrophy were included in the successful testicular salvage group. The predictive factors affecting testicular salvage were determined using univariate and multivariate logistic regression analyses; a nomogram was constructed. The nomogram was verified using data from the validation group. RESULTS: Using multivariate logistic regression analysis, the independent risk factors of testicular salvage after testicular torsion were symptom duration (p = 0.034), intratesticular blood flow (p = 0.003), spermatic cord torsion degree (p = 0.037), and monocyte count (odds ratio: 0.012, p = 0.036). A nomogram was established based on these four risk factors. In the training cohort, the area under the receiver operating characteristic curve was 0.969. The area under the receiver operating characteristic curve of the verification cohort was 0.965, indicating good discrimination ability of the nomogram. Increased symptom duration without intratesticular blood flow increased the monocyte count and spermatic cord torsion degree and decreased the success rate of testicular salvage. CONCLUSION: This prediction model could obtain the corresponding probability of testicular salvage according to the clinical characteristics of different patients with testicular torsion, providing reference for clinicians and parents.

PURPOSE: We assessed the stiffness of unilateral undescended testes after orchiopexy, examining its value in tracking histopathological changes and fertility potential during postoperative follow-up. Additionally, we explored the optimal timing for surgery based on testicular stiffness. PATIENTS AND METHODS: Thirty-six boys who had been diagnosed with unilateral undescended testis and treated with orchiopexy were included in the study. Testicular stiffness was evaluated several times over respective follow-up periods by ultrasound strain elastography after orchiopexy. The strain ratios were measured as the ratios of the elasticities of the descended testis to those of the operated testes. The patients were divided into two groups based on the age at which they underwent orchiopexy:under < 2 years (Group A) and ≥ 2 years (Group B). RESULTS: The mean strain ratios were 0.90 ± 0.32 and 0.92 ± 0.20 in Groups A and B, respectively. In Group A, the strain ratio was constant regardless of postoperative months (r = 0.01, p = 0.99); however, in Group B, it tended to increase with postoperative months (r = 0.42, p = 0.07). CONCLUSIONS: Evaluation of testicular stiffness may be useful for the estimation of histopathological changes and fertility potential in boys with unilateral undescended testes at follow-up appointments after orchiopexy. Our data indicate that performing orchiopexy as early as possible may be recommended to avoid testicular damage.

BACKGROUND: Staged laparoscopic management of intra-abdominal testes using pedicular section is recognized as gold standard technique, successful in 85 % of cases for scrotal testicular position with less than 10 % testicular atrophy. Recently, Shehata proposed a new technique without pedicular division for these testes, using spermatic vessels traction, but did not provide a comparative study of the two techniques. OBJECTIVE: To evaluate the laparoscopic spermatic pedicular traction (Shehata technique, ST) for the treatment of intra-abdominal testis, as an alternative to gold standard pedicular section (2-stage Fowler-Stephens, FS). STUDY DESIGN: Intra-abdominal testes of 129 patients in two tertiary pediatric urology centers were managed laparoscopically (2011-2019) either by 2-stage FS orchidopexy or ST according to the surgeon preference. Testicular position and size were statistically compared. RESULTS: A total of 147 testes were pulled down by 80 ST and 67 FS, including 18 bilateral cases. Median (IQR) age at surgery was 24.2 (15.6-46.4) months (ST) and 18.3 (13.1-38.2) months (FS) (p = 0.094). Scrotal pulling-down of the testis was performed after a median (IQR) period of 2.3 (1.6-3.4) months (ST) and 6.1 (4.7-8.3) months (FS), respectively (p < 0.005). Although ST had collapsed in 17 cases (21.3 %), only one (1.3 %) redo procedure was required. After a median (IQR) follow-up of 22 (12-40) and 19 (8.75-37) months (p = 0.59), the testis was in the scrotum in 85 % and 81 % of ST and FS cases, respectively (p = 0.51). Testicular atrophy occurred in 10 % of ST and 13.4 % of FS (p = 0.61). Multivariate analysis using the propensity score analysis did not identify any difference between the two techniques. DISCUSSION: Our results seem to confirm that FS and ST achieve the same results regarding final testicular position and testicular atrophy rate, with a long-term follow-up. Our study supports pediatric surgeons to favor laparoscopic spermatic pedicular traction (ST) which preserves the testicular vascularization and may ensure better spermatogenesis after puberty. More details on the size and position of the testicle at the beginning of the first laparoscopy seem however essential to assess more accurately the outcomes of each surgical technique. Our outcomes will also be re-evaluated when our patients have reached puberty, from an exocrine and endocrine points of view. CONCLUSIONS: This study showed similar results after laparoscopic traction or section of spermatic vessels for intra-abdominal testis in a long-term follow-up, providing more evidence for the use of ST as a valuable alternative to FS.
