Intraoperative ultrasound in the conservative resection of testicular neoplasms

Area of Science:

• Urology
• Radiology
• Oncology

Background:

• Oligospermia can be associated with testicular abnormalities.
• Early detection of testicular tumors is crucial for fertility preservation and treatment outcomes.
• High-resolution ultrasound is a key imaging modality for evaluating testicular pathology.

Purpose of the Study:

• To investigate the utility of high-resolution ultrasound in detecting small testicular tumors in men with oligospermia.
• To evaluate the role of intraoperative ultrasound in guiding conservative tumor resection.
• To determine the pathological nature of incidentally detected testicular tumors in this cohort.

Main Methods:

• Retrospective analysis of approximately 400 patients evaluated for oligospermia.
• High-resolution real-time ultrasound for initial tumor detection.
• Intraoperative high-resolution ultrasound to assist in surgical resection.
• Pathological examination of resected tumor specimens.

Main Results:

• Four patients (1%) with oligospermia were found to have small (3-6 mm), clinically impalpable testicular tumors.
• Tumors were consistently identified on repeated sonograms.
• Intraoperative ultrasound facilitated conservative tumor resection, preserving testicular function.
• All four tumors were pathologically diagnosed as benign Leydig cell tumors.

Conclusions:

• High-resolution ultrasound is effective in detecting small, impalpable testicular tumors in men with oligospermia.
• Intraoperative ultrasound enables organ-sparing surgery for these lesions.
• Benign Leydig cell tumors appear to be the predominant pathology in this specific clinical scenario.
