Low-cord orchidectomy for testicular cancer: what would be different?

INTRODUCTION: High cord radical orchidectomy (HRCO) is accepted as the standard surgical approach in testicular cancer, however low cord orchidectomy (LCRO) can reduce the morbidity of operation without worsening the oncological outcomes. METHODS: We retrospectively re-examined the specimens of men to determine the level of spermatic cord invasion (SCI). Men who had proximal SCI with negative surgical margins after HRCO were assumed to have de-novo residual tumour if LCRO was performed. Others were assumed as oncologically similar. We examined the relation between pre-operative variables and SCI and proximal SCI to determine whether prediction of proximal SCI is possible. RESULTS: 196 patients were included. 22 (11%) had SCI and ten (5%) had proximal SCI. Four patients with proximal SCI had positive surgical margins even after HRCO and didn't require additional local treatment. Six patients were assumed to have de-novo residual tumour if LCRO was performed. All six patients were metastatic and had systemic chemotherapy. High platelet count, tumour size, N stage, S stage and M stage were all significantly related with both SCI and proximal SCI (p < 0.05). CONCLUSION: Due to low probability of SCI, we think LCRO can safely be performed to reduce morbidity in Stage 1 patients. Although there is a risk for residual tumour in Stage 2-3 patients, currently there is no data that residual tumour would impair the success of systemic chemotherapy. Therefore we can not assume that these patients would be negatively affected. Pre-operative data can be useful to predict the presence of proximal SCI and select appropriate patients for LCRO.

[Construction of a predictive model for postoperative pain relief after microscopic spermatic cord surgery for spermatic cord pain].

OBJECTIVE: To explore the relevant factors affecting the efficacy of microscopic spermatic cord surgery and build a predictive model for postoperative pain relief. METHODS: A retrospective analysis was conducted on the clinical data of 324 patients with spermatic cord pain who visited the Department of Urology at Peking University People's Hospital between October 2015 and April 2023. This cohort included 212 patients with varicocele-related spermatic cord pain and 112 patients with idiopathic spermatic cord pain. All the patients underwent microsurgical procedures: varicocele-related pain was treated with microsurgical varicocelectomy, and idiopathic pain was treated with microsurgical denervation of the spermatic cord. The patients were categorized into effective and ineffective groups based on whether their pain had decreased by more than 50% six months post-surgery compared with pre-surgery levels. Baseline data were preliminarily screened for clinical indicators using t tests and univariate analysis. Clinical predictor variables [age, duration of pain, diameter of varicocele, patient health questionnaire-9 (PHQ-9) score, generalized anxiety disorder-7 (GAD-7) score] were selected using Lasso regression. A clinical prediction model for effective pain relief following microscopic spermatic cord surgery was constructed using Logistic regression and presented as a nomogram. The model's internal validation was performed using the bootstrap method. Its predictive power and clinical utility were evaluated through the concor-dance index, the area under the receiver operating characteristic curve, and calibration plots. RESULTS: Post-microscopic varicocele ligation, 156 patients (73.58%) experienced significant pain relief, as did 94 patients (83.93%) following microscopic denervation. Independent predictors for postoperative outcomes included age, PHQ-9 score, GAD-7 score, chronic pain duration, and varicocele diameter, differing slightly between varicocele-related and idiopathic pain groups. The models demonstrated excellent predictive ability, with areas under the curve of 0.909 and 0.913 for varicocele and idiopathic groups, respectively, and high concordance indices. CONCLUSION: The postoperative efficacy prediction model based on age, pain duration, PHQ-9 score, GAD-7 score, and varicocele diameter has good predictive ability and clinical applicability, and can be used in clinical practice.

Initial local resection versus early referral for spermatic cord sarcoma: Any impact on treatment timelines and oncological outcomes?

OBJECTIVES: Spermatic cord sarcomas are exceedingly rare, often misdiagnosed and subsequently improperly treated at local hospitals. This retrospective study looked at the oncological outcomes of spermatic cord sarcoma cases managed with curative intent resection at a tertiary referral sarcoma centre. We specifically studied how initial inadequate resections impact the oncologic outcomes compared to primary tumour resections at the reference centre. METHODS: One hundred eighteen consecutive patients affected by primary, localized spermatic cord sarcoma surgically managed at our reference centre from January 2001 through January 2021 were included. Primary endpoints were local relapse free (LRFS), distant metastasis free (DMFS) and overall survival (OS). These outcomes were evaluated with multi-nomial logistic regression and Cox proportional hazards regression models for a co-relation to known patient, tumour and treatment-related prognostic factors, including a prior inadequate resection and time from diagnosis to a complete oncologic resection as independent variables. Secondarily, we compared the above variables and treatment intervals among the subgroups of primary versus re-resection surgery. RESULTS: Over a median follow-up of 54 months (IQR 25-105), 12 patients (10.2%) developed local recurrence (LR) and 14 (11.6%) had distant metastasis (DM). 5-year local relapse (LRFS) and distant metastasis-free survival (DMFS) were 89.3% and 86.5%, respectively. Higher tumour grade and size were associated with a worse DMFS (p=<0.05). Likewise, marginal (R1) resection correlated with an inferior LRFS (p=< 0.05). Eighty-four patients (71.2%) had their initial diagnosis established on an inadequate surgical excision performed in a local hospital, followed by a re-excision at our centre (Re-resection group). During the same period, 34 (28.8%) were managed primarily with biopsy and treatment at our reference centre (Primary-resection group). The two groups had statistically significant differences in tumour size, histopathology, surgery duration, rate of postoperative complication and R0 resection (p < 0.005). Additionally, the difference in time intervals to achieve the treatment targets was statistically insignificant and did not correlate to the risk of recurrence as an independent variable. Residual disease was present in 51.2 % (n = 43) of the re-excision specimens. However, following a complete R0 resection, this did not correlate with a higher risk of recurrence (p = 0.481). CONCLUSION: Prompt referral to a tertiary centre, where multidisciplinary evaluation and sound oncologic resections are the standard of treatment, can align the OS and DFS of patients receiving incomplete surgery elsewhere to those treated primarily in referral centres. The primary determinant of prognosis remains surgical margin, tumour size and grade.

Staged laparoscopic orchiopexy of intra-abdominal testis: Spermatic vessels division versus traction? A multicentric comparative study.

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.

Liposarcoma of spermatic cord mimicking an inguinal hernia A case report and review of the literature.

AIM: Liposarcoma of the spermatic cord (LSC) is a tumour often mistaken for common inguinal swelling as hernia and the aim of this work is to present our case with a review of the Literature to define the management of this rare condition. MATERIAL OF STUDY: A systematic review has been realised, considering English language articles published on Pubmed, between 1956 and 2022, using as key words "Liposarcoma of the spermatic cord". RESULTS: 160 studies described 420 cases of LSC and in 40 cases the patient had undergone surgery with an initial diagnosis of inguinal hernia. DISCUSSION: LSC is a very rare entity of genitourinary malignancies, occurring more often in the spermatic cord and diagnosis can be difficult. Our case and Literature data confirm the role of imaging in not conventional inguinal swelling, to avoid diagnostic mistakes and to define preoperatively the correct surgical management. CONCLUSIONS: Imaging is mandatory in case of diagnostic doubt. The recommended treatment is a radical high orchiectomy with clear margins. A long follow-up period is necessary to detect a local recurrence which may occur even several years after the primary therapy. KEY WORDS: Inguinal swelling, Liposarcoma, Spermatic cord.

A systematic review and meta-analysis on the efficacy of internal spermatic artery ligation during laparoscopic varicocelectomy in children and adolescents: Is it safe?

INTRODUCTION: Challenges in identifying small testicular arteries and lack of microscopic experience have led to a rising trend in the use of laparoscopic technique for pediatric and adolescent varicocele. The controversy over artery ligation (AL) and artery preservation (AP) during laparoscopic varicocelectomy (LV) is still debatable. This study investigates the effectiveness of AL and AP during LV in pediatric and adolescent varicocele cases. METHODS: The systematic searches based on PRISMA guideline were conducted in PubMed, Scopus, ScienceDirect, Web of Science and ProQuest databases with pre-defined keywords. Both quantitative and qualitative analyses were performed to assess catch-up growth, persistence, recurrence, hydrocele, operative time, post-operative testicular volume, and sperm analysis. RESULTS: A total of 1512 patients from 9 eligible studies were included. There were no significant differences in catch up growth (OR 0.89; 95%CI 0.53, 1.51; p = 0.68) or hydrocele incidence (OR 0.59; 95%CI 0.28, 1.24; p = 0.16). The recurrence rate and persistence rate in AP group is significantly higher compared to AL group (OR 2.95; 95%CI 1.53, 5.68; p = 0.001 and OR 5.13; 95% CI 2.04, 12.88; p = 0.0005, respectively). The mean operative time during laparoscopic varicocelectomy is significantly longer when arteries are preserved as opposed to when they are ligated (OR 5.33; 95%CI 2.05, 8.60; p = 0.001). AL and AP both improved testicular volume and post-operative sperm analysis. CONCLUSIONS: AL showed higher efficacy and comparable safety to AP. We recommend using AL with lymphatic sparing to minimize hydrocele complications.

Reference value of testicular temperature measured by finite element analysis after first staged inguinal orchidopexy in children with abdominal testis and short spermatic cord.

PURPOSE: This study aims to build a 3D reconstruction computed simulation model and to establish a regression equation for detecting the testis's temperature by its location after first staged open orchidopexy in children with abdominal undescended testis (UDT) and short spermatic cords. METHODS: In this cross-sectional study, we enrolled 31 children with abdominal UDT and short spermatic cords who underwent first staged orchiopexy between 2017 and 2020. Using ultrasonography to obtain the testis's location distance from the skin surface (X1), external iliac vessel (X2), and internal inguinal ring (X3), we input the data into a 3D reconstruction computed simulation along with COMSOL to calculate the testicular temperature. We also used multivariate regression to establish the testicular temperature regression equation from the gathered data. RESULT: The mean age of the participants was 4.47 ± 1.21 years. The mean size of the operated testis was 0.39 ± 0.13 cc. The mean distance of the testis from X1, X2, and X3 was 3.27 ± 1.25 mm, 21.06 ± 6.42 mm, and 27.19 ± 10.09 mm, respectively. The testicular temperature regression equation derived from testis location was calculated by the formula: 34.57 + 0.0236 X12 - 0.0105 X2 - 0.0018 X3. The concordance for testis temperature calculated via the computational method and regression equation was 83%. CONCLUSIONS: The current study provided a reference value for the testicular temperature of children with abdominal UDT and short spermatic cords after the first stage of orchiopexy. A testicular temperature regression equation can be established based on the testis location, which will provide relevant information for the testicular development assessment, disease diagnosis, and follow-up, and possibly determination of the time of the second stage of orchiopexy.

A large dermoid cyst of the spermatic cord.

Dermoid cysts of the spermatic cord are rare, with only a few adult cases published in the literature. We report a patient with a 10cm inguinal mass referred to us for a suspected paratesticular sarcoma. Imaging suggested a cyst but, due to the recent increase in size, the cyst contents were evacuated and the cyst wall was biopsied. Histopathology revealed a dermoid cyst, which is a benign variant of cystic teratomas. Histopathological examination was required here due to the uncertainty. Careful interpretation was required, as cystic teratomas very occasionally undergo a malignant transformation.

Comparison of spermatic cord ligation and the vas plexus ligation in canine orchiectomy: A prospective clinical study.

BACKGROUND: Orchiectomy with a vas deferens to pampiniform plexus ligation (VPL) is a novel method, and it is unclear how its short-term outcomes compare with the results of a conventional method, spermatic cord ligation (SCL). OBJECTIVE: To compare the short-term outcomes of SCL and VPL on inflammation, surgery time, bleeding, pain and surgeon satisfaction during canine open orchiectomy. METHODS: Thirty male crossbred dogs undergoing open orchiectomy were enrolled the study. Dogs were randomly allocated to one of the SCL or VPL groups, with 15 patients in each. In the SCL group, the spermatic cord was ligated using absorbable sutures. The vas deferens, and pampiniform plexus self-tying were performed in the VPL group. Surgery time, bleeding and surgeon satisfaction scores were recorded. Inflammation at the surgical site was assessed using infrared thermal camera over three days, and pain associated with inflammation was scored on the third day. RESULTS: On Day 3, the average temperature in the SCL group was significantly higher than that of the VPL group, with a mean difference of 4.63°C (95% CI: 2.34-6.93, p < 0.001). Moreover, the surgery time in the VPL group was significantly longer compared to the SCL group, with a mean difference of 1.7 min (95% CI: 0.28-3.11, p = 0.021). The bleeding score was also significantly higher in the VPL group (p = 0.012). On the other hand, surgeon satisfaction and pain scores were not significantly different between groups. CONCLUSION: Both SCL and VPL methods are safe and effective for orchiectomy in dogs. VPL is comparable in efficacy and safety and has the additional benefit of less inflammation.

Extremely rare pediatric primary scrotum tumor: spermatic cord hemolymphangioma for a case report and literature review.

Hemolymphangioma is an uncommon benign tumor type that commonly occurs in the head and neck. Primary spermatic cord hemolymphangioma (SCH) with only several reported, however, is extremely rare. Clinical diagnosis can be challenging because of its rarity. Although spermatic cord hemolymphangiomas are benign tumors, there is still a high recurrence rate in postoperative. A 15-year-old boy presented to our hospital with complaints of scrotal for 15 days and did not have other associated symptoms. The male genital color Doppler ultrasound revealed that a cystic echo in the left spermatic cord region and above the testes was about 32 mm × 20 mm × 14 mm. He underwent left en bloc scrotum tumor resection under general anesthesia, and pathologic examination showed SCH. He was discharged from the hospital in the second postoperative day. After 1-month follow-up, the patient recovered well without recurrence. The patient is currently in follow-up phase. Up to date, only a few cases have been reported in the literature about SCH. So, we hope to raise the awareness of the diagnosis of SCH in clinical practice although this case.

A case of spermatic cord B-cell lymphoma relapsing to the brain in a dog.

A 13-year-old, intact male mixed-breed dog was referred to our clinic for lethargy and asthenia following an episode of gastroenteritis. As an incidental finding during abdominal ultrasound, a mass on the right spermatic cord was seen. Cytology of the mass revealed a monomorphic population of large, round cells with a lymphoid appearance. A bilateral orchiectomy was conducted, and histopathology revealed the presence of a B-cell lymphoma in the right spermatic cord. Based on clinical staging, which showed no involvement of other sites, no additional treatment was administered. Recheck evaluations were scheduled for every 3 mo thereafter. Five months after surgery, the dog developed left central vestibular syndrome with a paradoxical right-sided head tilt. An MRI of the brain showed multifocal lesions and, due to a rapidly worsening clinical condition, the dog was humanely euthanized. The histopathology of the brain lesions was consistent with B-cell lymphoma. Key clinical message: This is the first report of a primary spermatic cord lymphoma relapsing to the brain in a dog. Although rare, spermatic cord tumors should be included among the differential diagnoses for masses arising from the spermatic cord. If lymphoma is diagnosed, location to other sites, especially to the central nervous system, should be considered.

Un cas de lymphome à cellules B du cordon spermatique récidivant au cerveau chez un chien. Un chien de race mixte mâle intact de 13 ans a été référé à notre clinique pour léthargie et asthénie à la suite d'un épisode de gastro-entérite. Comme découverte fortuite lors d'une échographie abdominale, une masse sur le cordon spermatique droit a été observée. La cytologie de la masse a révélé une population monomorphe de grosses cellules rondes d'aspect lymphoïde. Une orchidectomie bilatérale a été réalisée et l'histopathologie a révélé la présence d'un lymphome à cellules B dans le cordon spermatique droit. Sur la base du stade clinique, qui n'a montré aucune implication d'autres sites, aucun traitement supplémentaire n'a été administré. Des évaluations de contrôle étaient programmées tous les 3 mois par la suite. Cinq mois après la chirurgie, le chien a développé un syndrome vestibulaire central gauche avec une inclinaison paradoxale de la tête du côté droit. Une IRM du cerveau a montré des lésions multifocales et, en raison d'une détérioration rapide de l'état clinique, le chien a été euthanasié sans cruauté. L'histopathologie des lésions cérébrales correspondait à un lymphome à cellules B.Message clinique clé :Il s'agit du premier rapport d'un lymphome primaire du cordon spermatique récidivant au cerveau chez un chien. Bien que rares, les tumeurs du cordon spermatique doivent être incluses dans les diagnostics différentiels des masses provenant du cordon spermatique. Si un lymphome est diagnostiqué, la localisation vers d'autres sites, en particulier vers le système nerveux central, doit être envisagée.(Traduit par Dr Serge Messier).

Robot-assisted laparoscopic varicocelectomy in a pediatric population.

PURPOSE: To present our experience with robot-assisted laparoscopic varicocelectomy in a pediatric population. METHODS: We reviewed 49 consecutive cases performed by the same experienced surgeon. One-to-four veins were ligated at the internal ring of the inguinal canal, while the testicular artery and lymphatics were spared. Information on patient characteristics, surgical time, complications, and recurrences were collected. RESULTS: Median patient age was 14 (range 10-17) years. Forty-eight had left-sided varicoceles and one had a bilateral varicocele. Forty-five were grade 3. All patients were referred due to discomfort/pain and 20 also had reduced testicular size. The median operating time from skin incision was 48 min (31-89 min) and the median console time was 18 min (7-55 min). Forty-seven patients were discharged the same day. Two patients experienced pain and problems urinating, respectively. These issues had resolved by the first post-operative day. There were no other complications, but at 6 months, eight recurrences were noted (16%). Scrotal complaints had subsided in all patients. Catch-up growth of the affected testicles was seen in 19/20 cases. CONCLUSION: Robot-assisted laparoscopic varicocelectomy is feasible and safe in a pediatric population but with a relatively high recurrence rate.

Spermatic cord leiomyosarcoma in a young male: A case report and literature review.

Spermatic cord Leiomyosarcoma is an extremely rare intrascrotal tumour. Owing to its rarity, no definitive management guidelines have been formulated as yet. The majority of published literature comprises of case reports or case series and show varying outcomes depending upon multiple patient- and disease-related factors. Almost all cases are older adults with majority in the sixth or seventh decades of life. It is commonly labelled as an indolent curable tumour if treated Spermatic cord Leiomyosarcoma is an extremely rare intrascrotal tumour. Owing to its rarity, no definitive management guidelines have been formulated as yet. The majority of published literature comprises of case reports or case series and show varying outcomes depending upon multiple patient- and disease-related factors. Almost all cases are older adults with majority in the sixth or seventh decades of life. It is commonly labelled as an indolent curable tumour if treated early by radical orchiectomy. The role of lymphadenectomy, adjuvant radiotherapy or chemotherapy is unclear. This case report concerns a young 38-year-old man who suffered from a painless firm left hemiscrotal mass for the past two years. Ultrasonography showed an intrascrotal paratesticular mass. Metastatic workup was negative. Left radical orchiectomy was performed and histopathology of the surgical specimen revealed leiomyosarcoma of the spermatic cord. The patient is on post-surgery follow-up and disease-free for six months. A literature review is also presented.

Internal Spermatic Vein to Superficial Epigastric Vein Microsurgical Bypass in Varicocele Treatment.

INTRODUCTION: Identification and preservation of testicular artery and lymphatic vessels during microsurgical varicocelectomy can be tedious if adhered encompassing venous network is encountered. A venous bypass from internal spermatic to saphenous or inferior epigastric vein, that have been described for varicocele treatment, may be used in such situations. This paper describes a simplified modification of the venous bypass technique that reroutes the testicular blood to the superficial epigastric vein, which can easily be found in the incisional wound. Surgical technique and anastomotic patency test are described, and indications and results are discussed. MATERIALS AND METHODS: During 2020 and 2021, 32 adolescent patients underwent microsurgical varicocelectomy. In eight patients additional microsurgical testicular vein-superficial epigastric vein microvascular bypass was done. The indication for bypass was difficult identification of testicular artery and/or lymphatic vessels due to adhered venous plexus. RESULTS: Varicocele resolution was noted in all eight patients with clinical and/or semen analysis improvement. There were no complications or recurrences. Average length of procedure was 65 minutes. All patients were discharged within 24 hours and no antiplatelet or anticoagulant therapy was used. CONCLUSION: Testicular vein to superficial epigastric vein anastomosis is a useful and simplified venous bypass technique that reroutes the blood from the pampiniform plexus to the femoral vein. It can be done as an adjunct to microsurgical varicocelectomy in selected patients through a standard incision.

Splenogonadal fusion misdiagnosed as spermatic cord cyst: a case report.

INTRODUCTION: Splenogonadal fusion is a rare congenital anomaly. The aim of this study was to report a case of splenogonadal fusion mimicking a spermatic cord cyst, and discuss therapeutic management of this rare congenital malformation. OBSERVATION: An eight-years old patient was presented with an asymptomatic three-centimeter oval scrotal mass mistaken for a spermatic cord cyst. Surgical exploration has revealed tow purple-red, firm encapsulated masses. The first mass was two cm long and adherent to the upper pole of the left testis with a cleavage plane. The second mass was four cm long, attached to the first by a fibrous cord and drawn on its superior pole by a serpiginous vascular structure that extended inside the abdomen. The spermatic cord was individualized. Extemporaneous anatomopathological examination of the first mass, totally excised, has concluded to benign lesion. Therefore, the peritoneum was opened, and the superior mass was excised as high as it could be reached without orchiectomy. Definitive Anatomopathological examination concluded to an ectopic splenic tissue. The final diagnosis was a continuous splenogonadal fusion. CONCLUSION: This case highlights the clinical characteristics of this condition, with a special focus on the signs and findings that might help prevent unnecessary orchiectomy. Consequently, it is essential to include this malformation in the differential diagnosis of scrotal masses in children.
