The aim of the study was to retrospectively evaluate our series of Testis Sparing Surgery (TSS) relating to the last 10 years and to discuss the feasibility, safety, and outcome of this treatment modality.Patients and Methods: we here present a series of 10 pediatric patients ranging from 9 to 15 years (mean age 11.9yrs) referred to our Institution for mono lateral testicular lesion accidentally detected at US or for indefinite testicular pain and submitted to TSS. The lesions measured from 6 to 20mm (mean 13.1 mm). Histological diagnosis showed 2 residues of adrenocortical tissue,1 epidermoid cyst,3 Large cell calcifying Sertoli cell tumor, 2 Leydig cell tumors; 1 Leydig cell hypertrophia; 1 gonadoblastoma. Surgery was performed through an inguinal approach by cold ischemia and with organ-sparing surgery.Results: Neither of the patients exhibited intraoperative or postoperative complications. After a mean follow-p of 6.7 years the patients were free of disease. Conclusion:Testis-sparing surgery by cold ischemia and frozen-section examination is advisable for pediatric patients with benign testicular masses. Short CommunicationUntil the 1980s, orchiectomy was generally considered the sole therapy fortesticular nodules, particularly in case of pediatric patients. However, there is actually a risk of overtreatment by radical orchiectomy, especially for clinically silent small lesions only detected by ultrasound (US) [1].The high level of accuracy achieved by frozen-section examination (FSE) for identification of both benign and malignant lesions, and the increasing attention paid to the cosmetic, functional, and psychological outcomes for young patients with testicular tumors strongly support an organsparing approach. The aim of this report was to retrospectively evaluate our series of Testis Sparing Surgery relating to the last 10 years and to discuss the feasibility, safety, and outcome of this treatment modality. Patients and MethodsBefore the surgery, all patients had undergone complete clinical and instrumental staging, including clinical examination, scrotal US, and computed tomography (CT) scans (abdominal and lung). Furthermore, the tumor markers alpha fetoprotein (AFP), betahuman chorionic gonadotropin (β-hCG), and lactate dehydrogenase (LDH) were evaluated to rule out a potential malignancy. Ultrasound was performed using high-frequency linear-array transducer (8-13 MHz) that allowed for high-resolution imaging of the testicles with a maximum lateral spatial resolution of 0.1 mm. Our case-series includes 10 patients, ranging from 9 to 15 years (mean age 11.9 years), who were referred to our Institution for mono lateral
