Objective: To evaluate radionuclide scrotal imaging (RSI) in the diagnosis of varicocele.
Methods: We performed physical examination (PE) and RSI for 126 patients with infertility for at least 12 months and seminal abnormality, obtained the scrotal blood-pool index (SBPI), observed the reflux in the spermatic vein during RSI, typed and graded varicocele by color Doppler flow imaging (CDFI) and compared the results of PE and RSI with those of CDFI.
Results: The rates of sensitivity and specificity of RSI in the diagnosis of varicocele (96.5% and 97.1%) were both higher than those of PE (71.7% and 69.1%).
Conclusion: Simple, accurate and noninvasive, RSI is an effective method for the diagnosis of clinical and subclinical varicocele.

Objectives: The Scrotal and Penile Imaging Working Group (SPIWG) of the European Society of Urogenital Radiology (ESUR) aimed to formulate recommendations on the imaging modalities and minimal technical requirements for abdominopelvic imaging in the follow-up of adult patients treated for testicular germ-cell tumors (TGCT).
Methods: The SPIWG members performed an extensive literature search, reviewed the current clinical practice, and reached a consensus based on the opinions of experts in the field.
Results: Recurrence in patients treated for TGCT mainly occurs in retroperitoneal lymph nodes (LNs).

Semen analysis is universally regarded as the gold standard for diagnosing male infertility, while ultrasonography plays a vital role as a complementary diagnostic tool. This study aims to assess the effectiveness of artificial intelligence (AI)-driven deep learning algorithms in predicting semen analysis parameters based on testicular ultrasonography images. This study included male patients aged 18-54 who sought evaluation for infertility at the Urology Outpatient Clinic of our hospital between February 2022 and April 2023.

Splenogonadal fusion is a rare congenital anomaly characterized by an unusual linkage between ectopic splenic tissue and the gonad, with a higher prevalence observed in the males. While the majority of the splenogonadal fusion cases are associated with cryptorchidism, the patients may have other congenital malformations such as inguinal hernias. Despite being benign and having a rare occurrence, the preoperative diagnosis of splenogonadal fusion is a challenging one.

Magnetic resonance imaging is an essential tool for the assessment of the scrotum, particularly in cases with inconclusive ultrasound findings. It has a great capacity to differentiate between intratesticular and extratesticular lesions, as well as between neoplastic and non-neoplastic lesions. By providing an accurate characterization of lesions, magnetic resonance imaging plays a crucial role in preoperative tumor staging and decision-making.
