ABSTRACT
BACKGROUND/AIMS: Ischemic reperfusion (I-R) injury is greatly influenced by the testicular torsion/detorsion process (TDP). In this instance, the anti-inflammatory properties of plateletrich plasma (PRP) combined with tadalafil (Td) significantly promote tissue healing in the I-R injury model. METHODS: Five groups of rats were created: the control group, the I-R group not receiving any therapy, the I-R group receiving a single dosage of Td (0.25 mg/kg, I.P.), the I-R group receiving a single dose of PRP (80 l, intratesticular), and the I-R group receiving both Td and PRP. Sperm morphology, motility, and histology were assessed. The levels of TNF-, BAX, antioxidant status, and testosterone were measured. Additionally, E-selectin expression was done. RESULTS: PRP reduced oxidative stress, inflammation, and apoptosis while also boosting testosterone levels, which alleviated I-R injury. Otherwise, PRP reduces E-selectin expression, which modifies the pathways that control endothelial function. Td also partially demonstrated its testicular-protective activity at the same time. CONCLUSION: PRP's proven anti-inflammatory, antioxidant, and antiapoptotic potentials make it a natural treatment for testicular harm caused by tadalafil. For the first time, it was demonstrated that PRP therapy restored the functionality of the vascular endothelium, specifically the control of E-selectin expression. Combining Td and PRP therapy may be a promising strategy for improving response to PDE5 inhibitors.

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.

AIMS: The aim of this study was to investigate the potential antioxidant, anti-inflammatory, and sperm function-preserving properties of sodium acetate (ACE), a histone deacetylase (HDAC) inhibitor, in a rat model of testicular torsion/detorsion (T/D). MAIN METHODS: Littermate Wistar rats of identical weight were subjected to sham surgery or testicular T/D by rotating the left testis at 720° around its axis along the spermatic cord clockwise and fixing it in this position for two and a half hours. 1 h before detorsion, T/D + ACE-treated rats were treated with ACE (200 mg/kg/day, per os) while T/D rats were vehicle-treated by administering 0.5 mL of distilled water. After 72 h, animals were euthanized, and the left testes were harvested for bio-molecular and histological analysis. KEY FINDINGS: Acetate administration attenuated T/D-induced rises in serum and testicular HDAC and testicular xanthine oxidase, uric acid, MDA, GSSG, MPO, TNF-α, IL-1ß, IL-6, NFkB, HIF-1α, and VCAM-1. In addition, acetate treatment alleviated T/D-induced decline in sperm quality (count, motility, viability, and normal morphology) and testicular 3ß-HSD, 17ß-HSD, testosterone, GSH, GSH/GSSG, SOD, catalase, GPx, GST, Nrf2, and HO-1. Furthermore, acetate prevented T/D-distorted testicular histoarchitecture and spermatogenic germ cell loss. SIGNIFICANCE: Sodium acetate during the post-ischaemic phase of testicular T/D may be beneficial in preventing I/R injury and maintaining fertility.

BACKGROUND: Cryptorchidism and testicular torsion (TT) are relatively common conditions in clinical practice; however, sparse information about cryptorchid TT is available in the current literature. METHODS: We retrospectively reviewed the clinical characteristics, treatment modalities, and long-term outcomes of pediatric patients treated for acute cryptorchid TT. RESULTS: We found eight patients with unilateral acute cryptorchid TT with a prevalence of 8.9% (8/90) among all TT cases. The left testis was affected in six patients. The median age of patients at the time of the surgery was 65 months (interquartile range (IQR) 4-136 months). The median duration of symptoms was 16 h (IQR 9-25 h), while the median time to treatment was 60 min (IQR 59-63 min). The most common symptoms were pain (abdominal and inguinal) and inguinal mass with no palpable testis in the ipsilateral hemiscrotum. Preoperative color Doppler ultrasonography revealed absent or decreased testicular blood flow in the affected testes in 7/8 of patients. Various degrees of testicular torsion (median 540°, min 360°, max 1260°) were found during surgery. A necrotic testis that led to orchidectomy was found in 4/8 of patients. The median follow-up period was 42.6 months (IQR 12.5-71.2 months), revealing only one patient with testicular atrophy. The final testicular salvage rate was 35%. CONCLUSIONS: Greater awareness among caregivers and primary care physicians about acute cryptorchid TT is required to improve their timely diagnosis and treatment. A physical examination of the external genitalia and inguinal regions should be mandatory to attain a proper diagnosis and treatment without delay.

INTRODUCTION: The management of acute scrotal swelling can be challenging in neonatal age, with scrotal abscess being great mimickers of testicular torsion. CASE PRESENTATION: We report a 12-day-old previously healthy male infant who presented with 72 h of increasing right-sided scrotal swelling, without fever or irritable behavior. The left testicle was palpable, but the right side was too swollen to palpate a testicle, with absent cremasteric reflex. Biochemical analysis was normal and Doppler sonography demonstrated a hypoechogenic avascular lesion compressing the right testis, without intratesticular flow. Due to these findings, surgical exploration was undertaken on suspicion of potential testicular torsion. Purulent material was encountered and cultured. The testis and epididymis were covered by thick necrotic fibrinous exudate, with no spermatic cord torsion. Gentamicin and vancomycin were begun immediately. The patient remained afebrile and the scrotal induration gradually subsided. Urine and blood cultures were sterile. On the second postoperative day, cultures yielded Escherichia coli sensitive to gentamicin. One-month follow-up testicular ultrasound demonstrated complete inflammation resolution. CONCLUSION: Paratesticular abscess may be considered as the greatest mimicker of testicular neonatal torsion, due to the frequent absence of classical signs of inflammation. Early surgical exploration can be diagnostic and therapeutic and should be performed in these cases.

PURPOSE: This pilot study evaluated indocyanine green-guided near-infrared fluorescence (ICG-NIRF) imaging of testicular blood flow to predict long-term testicular atrophy after testicular torsion (TT) surgery. METHODS: The subjects of this retrospective study were patients who underwent surgery for TT at our hospital between December, 2020 and July, 2022. After detorsion, testicular blood flow was evaluated by ICG-NIRF imaging and classified into three categories: fluorescence detected, no fluorescence detected, and fluorescence detected only in the tunica albuginea vessels. Testicular volume was measured by ultrasonography up to 12 months after surgery to evaluate long-term outcomes. RESULTS: Twelve patients were included in this analysis. We found a 100% correlation between the absence of ICG-NIRF signals and subsequent testicular atrophy. In three patients without an ICG-NIRF signal, the median testis size 12 months postoperatively was significantly smaller (16.5% of the contralateral testis; range 13-20%) than that in six patients with an ICG-NIRF signal (96%; 89-115%) (p = 0.013). Mild atrophy (74.5%; 73-76%) was also observed in the three patients for whom an ICG-NIRF signal was detected only in the tunica albuginea vessels. CONCLUSIONS: Our pilot study highlights the potential of ICG-NIRF imaging as a prognostic tool for guiding surgical decision-making for patients with TT, by predicting postoperative testicular atrophy.
ABSTRACT
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: Ultrasound as a diagnostic tool in suspicion of testicular torsion is still highly debated. In this investigation, we aimed to evaluate whether time spent on scrotal ultrasonography had a negative impact on testicular loss. METHODS: Patients' records containing a scrotal ultrasound and/or surgical procedure codes for testicular interventions on suspicion of testicular torsion were examined. Patients aged 0-15 years admitted during 2015-2019 at Copenhagen University Hospital, Rigshospitalet were included. RESULTS: In total, 1566 patients underwent an ultrasound and 142 of these proceeded to surgery while 13 patients proceeded directly to surgery without an ultrasound. The rate of testicular loss with a preceding ultrasound was 23% versus 42% without (p = 0.18). Four cases of testicular torsion were misdiagnosed by ultrasound resulting in a sensitivity of 95.4% and specificity of 95.6%. The mean diagnostic delay from ultrasound examination was 55 ± 39 min, and the mean time from ultrasound to surgery was at 169 ± 76 min versus 171 ± 72 min without ultrasound. CONCLUSION: In a clinical setting, ultrasound provided a reliable tool for the diagnosis of testicular torsion and did not seem to increase the orchiectomy rate.

BACKGROUND: Literature on paediatric surgical conditions in low- and middle-income countries (LMICs) remains limited. As a common emergency, timely treatment of testicular torsion acts as a benchmark of adequate emergency service delivery in paediatric surgery. This scoping study aims to synthesise all existing literature on paediatric testicular torsion in LMICs. METHODS: A database search was conducted by the OxPLORE global paediatric surgery research group to identify studies containing the terms 'testicular torsion' or 'acute scrotum' originating from LMICs. A thematic analysis was applied to the results of the search and the quality of evidence was appraised for all included articles. RESULTS: This review included 17 studies with 1798 patients. All studies originated from middle-income countries and the majority (76%) had sample sizes smaller than 100 patients. All studies were appraised as providing less than adequate evidence. Included studies identified long delays to treatment and highlighted ongoing debates on the value of scoring systems and Doppler ultrasonography in diagnosing torsion. Major heterogeneity in surgical approaches to treatment of testicular torsion in children was also observed. CONCLUSIONS: Literature on paediatric testicular torsion in LMICs is scarce and heterogeneous. Prospective, multi-centre research on the management of this common paediatric surgical emergency is urgently required.

Objectiveï¼ To explore the influence of environment temperature on the incidence of testicular torsion. METHODS: We collected the clinical data on 172 cases of testicular torsion diagnosed in the Second Hospital of Hebei Medical University from December 2013 to December 2020. According to the local environment temperature on the day of onset, we divided the patients into groups A (below 0â), B (0ï¼10â), C (10ï¼20â) and D (above 20â), and compared the incidence rates of testicular torsion among the four groups, followed by correlation analysis. RESULTS: The incidence rate of testicular torsion was 12.8% (n = 22) in group A, 35.5% (n = 61) in B, 34.9% (n = 60) in C and 16.9% (n = 29) in D, the highest at 0ï¼10â in group B, with statistically significant difference among the four groups (χ2 = 29.07, P <0.001). Spearman correlation analysis indicated that the incidence of testicular torsion was negatively correlated with the environment temperature (r = ï¼0.261, P <0.01), with no statistically significant difference among different seasons (χ2 = 5.349, P >0.05), but higher in autumn and winter than in the other two seasons. CONCLUSION: The incidence of testicular torsion is negatively correlated with the environment temperature, elevated when the temperature decreases, but has no statistically significant difference among different seasons, though relatively higher in autumn and winter.

Introduction: Dirofilarial infestation has been reported as an extremely rare cause of pediatric acute scrotum. We aimed to evaluate clinical, radiological, and intraoperative findings of children who underwent surgical management for acute scrotum due to dirofilariasis in an endemic country. Materials and Methods: A retrospective study of patient records of children who underwent surgery for acute scrotum due to dirofilariasis between 2018 and 2022. Results: There were eight emergency presentations for acute scrotum due to dirofilariasis. Three presentations (37.5%) were not associated with scrotal pain. The median age at presentation was 59 (range: 19-100) months. Four patients (67.7%) underwent emergency scrotal exploration at the first presentation and another one during the second presentation. Recurrent episodes were seen in two patients who were initially managed nonsurgically with antibiotics alone. Ultrasonography was performed in all six patients and revealed a parasitic nodule in three (50%). Conclusions: Dirofilariasis causing acute scrotum may cause significant diagnostic dilemma for clinicians. It may resemble idiopathic scrotal edema since it predominantly affects boys under 6 years of age and is painless in a significant proportion. However, left unoperated, it appears to have a high recurrence rate.
ABSTRACT
Torsion of the spermatic cord is a urological emergency that must be treated immediately with surgery, yet detorsion of the testis can cause testicular tissue damage because of ischemia-reperfusion (I/R) injury. I/R injury is a complex pathophysiological process that may affect the functions of distant organs. Here, we examined whether testicular torsion/detorsion (TT) causes myocardial dysfunction. We next investigated the potential beneficial effect and underlying mechanisms of remote ischemic postconditioning (RIPost) on cardiac function after testicular torsion/detorsion. Male Sprague-Dawley rats were assigned to three different sets of experimental groups. Testicular I/R was induced by rotating the right testis to 1080° clockwise for 3 h followed by 3 h of detorsion. RIPost was induced at the onset of testicular detorsion by four cycles of 5-min bilateral femoral artery occlusion with 5-min reperfusion. Cardiac function was determined postdetorsion, and the cardioprotective effect of RIPost was examined. Testicular torsion/detorsion-treated rats had reduced serum testosterone levels, impaired systemic hemodynamics, elevated systemic inflammatory responses, and increased serum levels of lactate dehydrogenase (LDH), creatine kinase-MB (CK-MB), α-hydroxybutyrate dehydrogenase (α-HBDH), and cardiac troponin I (cTnI). However, RIPost attenuated remote heart dysfunction induced by testicular torsion/detorsion. Furthermore, RIPost enhanced the phosphorylation of ventricular signal transducer and activator of transcription (STAT)-3, which is a key component of the survivor activating factor enhancement (SAFE) signaling pathways. Inhibition of STAT-3 with Ag490 abolished the RIPost-induced cardioprotection and STAT-3 phosphorylation. Testicular torsion followed by detorsion may cause impaired cardiac function in rats. RIPost effectively attenuates this remote cardiac dysfunction. RIPost-induced protective effects may be mediated by the STAT-3 signaling pathway.

STUDY QUESTION: Is prior testicular torsion associated with testicular function (semen quality and reproductive hormones) in young men from the general population? SUMMARY ANSWER: In young men from the general population, no differences in semen parameters were observed in those who had experienced testicular torsion compared to controls and observations of higher FSH and lower inhibin B were subtle. WHAT IS KNOWN ALREADY: Testicular function may be impaired after testicular torsion, but knowledge is sparse and based on studies with small sample sizes and no control group or a less than ideal control group. STUDY DESIGN, SIZE, DURATION: A cross-sectional population-based study was carried out including 7876 young Danish men with unknown fertility potential, examined from 1996 to 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS: All men (median age 19.0 years) had a physical examination, provided a blood and semen sample, and filled in a questionnaire including information about prior testicular torsion, birth, lifestyle and current and previous diseases. Markers of testicular function, including testis volume, semen parameters and reproductive hormones, were compared between men operated for testicular torsion and controls, using multiple linear regression analyses. MAIN RESULTS AND THE ROLE OF CHANCE: The average participation rate was 24% for the entire study period. In total, 57 men (0.72%) were previously operated for testicular torsion (median age at surgery 13.4 years) of which five had only one remaining testicle. Men with prior testicular torsion were more often born preterm (25% versus 9.5% among controls), and they had significantly higher FSH and lower inhibin B levels, and a lower inhibin B/FSH ratio than controls in crude and adjusted models. The association was mainly driven by the subgroup of men who had undergone unilateral orchiectomy. No differences in semen parameters were observed. LIMITATIONS, REASONS FOR CAUTION: A limitation is the retrospective self-reported information on testicular torsion. Also, results should be interpreted with caution owing to the high uncertainty of the observed differences. WIDER IMPLICATIONS OF THE FINDINGS: Overall, the results of our study are reassuring for men who have experienced testicular torsion, especially when treated with orchiopexy, for whom reproductive hormone alterations were subtle and without obvious clinical relevance. Our study found no differences in semen parameters, but follow-up studies are needed to assess any long-term consequences for fertility.

INTRODUCTION: Testicular torsion is a serious condition that carries with it a high rate of morbidity. OBJECTIVE: This review highlights the pearls and pitfalls of testicular torsion, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION: Testicular torsion is a urological emergency that occurs with rotation of the testicle along its supporting ligaments leading to obstruction of vascular flow. A key risk factor is the presence of a bell-clapper deformity. The most common population affected includes children in a bimodal distribution with the most cases occurring in the first year of life and between 12 and 18 years, although cases do occur in adults. Acute, severe, unilateral scrotal pain is the most common presenting symptom. Nausea and vomiting are common, but the presence or absence of a cremasteric reflex is not a reliable indicator of disease. The TWIST score may assist with clinical decision making in patients presenting with acute testicular pain but should not be used in isolation. If torsion is suspected or confirmed, consultation with the urology specialist should not be delayed, as outcomes are time sensitive. Ultrasound can be used for diagnosis, but a normal ultrasound examination cannot exclude the diagnosis. Treatment includes emergent urology consultation for surgical exploration and detorsion, as well as symptomatic therapy in the ED. Manual detorsion can be attempted in the ED while awaiting transfer or consultation. CONCLUSIONS: An understanding of testicular torsion can assist emergency clinicians in diagnosing and managing this disease.

OBJECTIVES: Testicular torsion (TT) is a pediatric surgical emergency that requires prompt treatment. This study investigated the feasibility of point-of-care ultrasound (POCUS) for diagnosing TT in the pediatric emergency department (ED). METHODS: We retrospectively reviewed the medical records of patients, aged 18 years or younger, who visited a university-affiliated hospital pediatric ED with acute scrotal pain without trauma history and underwent diagnostic ultrasounds between January 2010 and October 2022. RESULTS: This study included 731 patients (median age: 9 years), Of these, 315 (43%) were in the POCUS-performed group: 188 in the POCUS-only group, and 127 in the POCUS-and-RADUS group. The other 416 patients (56.9%) were in the RADUS-only group. In total, 45 patients (6.2%) were diagnosed with TT (19 in the POCUS-performed group and 26 in the RADUS-only group). The sensitivity, specificity, and positive and negative predictive values of POCUS for diagnosing TT were 94.7%, 92.9%, 46.2%, and 99.6%, respectively. The median time to perform POCUS was shorter than RADUS (23 versus 61 minutes, P < .001). The POCUS-performed group had a shorter ED length of stay than the RADUS-only group (93 versus 170 minutes, P < .001). Among the patients diagnosed with TT, performing POCUS first did not significantly delay the ED process, including time to operation (250 versus 205 minutes, P = .142). CONCLUSIONS: For patients with acute scrotal pain, evaluation performed by pediatric emergency physicians using POCUS performs well in screening TT, and can decrease length of stay in the ED.

INTRODUCTION: There is an ongoing debate whether to perform orchiectomy or orchidopexy following testicular torsion (TT) in cases where the testis seems non-viable. The main problem is lack of objective criteria defining testicular viability. The aim of this study was to investigate the grade of injury in orchiectomy specimens obtained from cases of TT and its association with clinical findings. METHODS: This multicenter retrospective study involved double-blinded reassessment of the patient files and the pathological specimens using Mikuz classification to analyze the relation between clinical and pathological findings. RESULTS: A total of 289 patient charts from 14 centers were reviewed and 228 were included in this study. Twenty (8.8%) patients had grade 1 injury which refers to reversible injury. The clinical findings of these 20 patients were compared to 208 patients with higher grades of injury. As expected, there was statistically significant difference regarding duration of symptoms (p < 0.001); however, range was wide in both groups (as long as 96 h for grade 1 and as short as 7 h for higher grades). There was no statistically significant difference in any other variable including age (median 14 for both, p = 0.531), symptoms (pain: 19/20 vs. 189/202, p = 0.801; swelling: 13/19 vs. 168/197, p = 0.094), absence of blood flow in Doppler US (15/19 vs. 164/197, p = 0.635), or degree of torsion (median 720° for both, p = 0.172). CONCLUSION: Our study revealed necessity for better criteria to define viability of testis following TT. Histopathological injury appeared to be reversible even in some patients with more severe perioperative findings, late admission, or high degree of twisting. Our findings support the tendency for testicular fixation instead of orchiectomy as none of the clinical or perioperative findings could be attributed to high-grade injury.

INTRODUCTION: The association between blood markers and testicular viability after testicular torsion (TT) is not well known. We evaluated the role of complete blood count markers and C-reactive protein (CRP) in predicting testicular viability after TT. METHODS: Fifty men, ≥18 years of age, operated for TT between the years 2015-2020 were enrolled. Blood markers including neutrophil-, lymphocyte-, and platelet count, and CRP were obtained. Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were calculated. The study outcome was testicular salvage. RESULTS: Median age was 23 years (interquartile range [IQR]: 21, 31). Median duration of torsion was 10 h (IQR: 6, 42). Sonographic texture of the testis was homogenous in 27 (56%) patients and heterogenous in 21 (44%). During scrotal exploration, 36 patients (72%) underwent orchiopexy and 14 (28%) underwent orchiectomy. Patients who underwent orchiopexy were younger (22 years vs. 31 years, p = 0.009), had a shorter duration of torsion (median 8 h vs. 48 h, p < 0.001), and a homogenous texture on scrotal ultrasound (76.5 vs. 7.1%, p < 0.001). Median NLR, PLR, and CRP were higher among patients who underwent orchiectomy; however, these differences did not reach statistical significance. Patients with heterogenous echotexture were significantly more likely to undergo orchiectomy (odds ratio = 42, 95% confidence interval: 7, 831, adjusted p value = 0.009). CONCLUSIONS: We found no association between blood-based biomarkers and testicular viability after TT; however, testicular echotexture significantly predicted outcome.

INTRODUCTION: Testicular torsion refers to ischemia of the testicle due to twisting or rotation of the vessels supplying the testes. It is a urologic emergency requiring a high index of clinical suspicion and prompt surgical intervention with management aimed at avoiding testicular loss and resulting infertility. This paper gives an update on the current situation regarding this topic in low-income settings. The aim of this study was to determine testicular salvageability and its predictors amongst patients with testicular torsion at two tertiary African hospitals. METHODS: This was a hospital-based multicentre longitudinal study at two tertiary hospitals in western Uganda. Patients with acute scrotum were enrolled and evaluated for testicular torsion. Those with confirmed testicular torsion underwent surgery and salvageability was reported as the primary outcome. Predictors for testicular salvageability were determined using backward binary logistic regression in SPSS version 22. RESULTS: During the study period, 232 patients with acute scrotum were enrolled. The mean age was 35.3 (SD = 20.4) years. Forty-one (17.7%) patients had testicular torsion. Only 16 (39.0%) of patients with torsion had viable testes that were salvageable. Orchiectomy was performed on 25 patients (61.0%). At multivariate analysis, a patient who presented after 48 h from the onset of symptoms was 34.833 times more likely to have orchiectomy compared to one who presented within 12 h [AOR = 34.833, (95% CI = 5.020-60.711), P < 0.001]. CONCLUSION: In this study, the testicular salvage rate was low. The only predictor of salvageability was the time from the onset of symptoms to presentation. All males should be sensitized about the clinical features of testicular torsion to ensure early presentation to increase salvage rates.

PURPOSE: To investigate the effect of exosomes obtained from adipose-derived mesenchymal stem cells (AD-MSCs) on testicular ischemia-reperfusion (I/R) injury. METHODS: AD-MSCs from rat adipose tissue were cultured. Characterization of cells was evaluated with CD44, CD90, CD34 and CD45 antibodies. Exosomes from AD-MSCs were obtained with the miRCURY exosome isolation kit. 21 rats were divided into 3 groups. The I/R model was created as 720° torsion for 4 h and reperfusion for 4 h. In the Sham group (SG), only scrotal incision was made. 100 µl of medium in the torsion-control group (T-CG) and 100 µl of exosome in the treatment group (TG) were injected into the testicular parenchyma after detorsion. Johnsen scores of testicles were determined. Apoptosis was evaluated by the TUNEL method. RESULTS: It was observed that the seminiferous tubule structures were partially disrupted in T-CG, but normal in SG and TG. Johnsen scores in SG, T-CG, and TG were 8.64 ± 0.39, 7.71 ± 0.37, and 8.57 ± 0.39, respectively. Apoptotic cell distribution was 11.28 ± 5.25%, 60.58% ± 1.68% and 17.71 ± 8.34% in SG, T-CG and TG, respectively. In both parameters, the difference between SG and TG was insignificant (p > 0.05), the difference between T-CG/TG and SG/T-CG was significant (p < 0.05). CONCLUSION: Exosomes obtained from AD-MSCs are effective in preventing testicular I/R injury. This effect appears to occur because of suppression of apoptotic activity.

The acute scrotum (AS) in the pediatric population is a medical emergency. AS is usually caused by testicular torsion (TT) and torsion of the appendix testis (TAT). The current study explored which demographic and clinical characteristics can help distinguish between TT and TAT. We analyzed all children ≤16 years who underwent surgical exploration for AS. The patients were divided into Group 1/TT and Group 2/TAT. Ninety patients were included in the study (24 with TT and 66 with TAT). The peak incidence of TT was significantly higher than in the TAT group (p<0.001). Scrotal pain was more prevalent in the TAT group (p=0.02), whereas systemic signs (nausea/vomiting and abdominal pain) affected more frequently the TT patients (p=0.003 and p<0.001, respectively). The duration of symptoms was significantly longer in the TAT group (p<0.001). The duration of symptoms in the TT cohort significantly impacted the testicular salvage (p=0.008). Color Doppler ultrasound (CDUS) findings of absent/decreased testicular blood flow in the affected testis strongly favored the diagnosis of TT (p<0.001). The older age, shorter duration of symptoms, systemic signs, and CDUS findings can help distinguish between the two most common acute scrotum causes.
