Role and added value of contrast enhanced ultrasound of the painful scrotum in the emergency setting

Emergency imaging of the scrotum is part of routine medical practice. Indications include epididymitis/epididymo-orchitis, testicular torsion, trauma, tumors and infarction. Prompt diagnosis and management are needed to ensure optimal patient outcome. Ultrasound (US) is the initial, and often the only, imaging modality for testicular pathologies. Usually, B-mode and color Doppler US are adequate. In challenging cases, contrast-enhanced US (CEUS) facilitates final diagnosis or increases the examiner's confidence by confirming findings on non-enhanced US. This paper elaborates on the examination technique of CEUS for testicular pathologies, thereby showing its added value over baseline US techniques in the emergency setting.

Outcomes of Surgical Exploration of Acute Scrotal Pain Raising Suspicion of Testicular Torsion

Background and objective Testicular torsion (TT) is a surgical emergency, affecting approximately one in every 4000 males under the age of 25 years annually in the United States. In this study, we aimed to determine the outcomes of emergency scrotal surgical exploration of cases that raised suspicion of TT presenting to Salmaniya Medical Complex (SMC), Bahrain's largest secondary and tertiary care center. Methods This was a retrospective cohort study. The data were collected from the hospital's electronic medical record software (I-SEHA). The data included patient age, Doppler ultrasound (DUS) findings prior to any surgical procedure, type of surgical procedure, and the surgical findings of that procedure. Results Of the 198 patients who underwent scrotal exploration, 141 had presented with signs and symptoms suggestive of TT. The mean age of the patients was 22.3 ±9.3 years. Doppler imaging was performed preoperatively on 135 out of 141 (95.7%) patients. After scrotal exploration, 91.4% of the patients were found to have TT. The proportion of patients with salvageable testis was 78.7%. Conclusions The study found that surgical exploration remains the definitive method in the management of acute scrotum in TT patients. Our findings are in line with those from other similar studies and meta-analyses.

Manual detorsion in testicular torsion: 5 years of experience at a single center

PURPOSE

Testicular torsion is one of the most common causes of acute scrotum in pediatric age. The present study aimed to evaluate the role of preoperative manual detorsion in the management of testicular torsion.

METHODS

Retrospective data analysis of pediatric patients treated for acute testicular torsion at a tertiary center over the last 5 years. Manual detorsion was attempted by surgeon's preference. Successful manual detorsion was defined as complete pain resolution with a normal color Doppler ultrasound. All patients underwent surgical exploration. Patient data analyzed included: age, pain duration, site of onset, attempt of manual detorsion, pain relief after manual detorsion, color Doppler ultrasound results, surgical findings and outcome.

RESULTS

One hundred twenty-two patients were included. Manual detorsion was attempted in 48% (58/122) cases. Manual detorsion was successful in 26% (15/58) patients. In the unsuccessful, residual cord torsion was found at surgery in 27.5% (16/58); in the remaining 27, there was no cord torsion at surgery. Five patients (5/15) with successful manual detorsion underwent elective orchiopexy. Gonadal loss after manual detorsion (9%, 5/58) occurred after unsuccessful manual detorsion, all submitted to emergency surgery.

CONCLUSIONS

Testicular torsion warrants prompt detorsion. Manual detorsion is simple, immediately available, and maximizes testis salvage. A successful maneuver permits nonemergency orchiopexy. An algorithm for the management of testicular torsion that includes an attempt of manual detorsion prior to surgery is proposed.

The Sonographic Appearance of Polyorchidism: A Multiple Case Report

The traditional sonographic characteristic used to distinguish polyorchidism (PO) has been its homogeneous echotexture, which is similar or identical to the normal testicle. PO is most commonly found in the left hemi-scrotum but can also be identified in the right hemi-scrotum, inguinal canal, or abdominal cavity. The mediastinum of a testicle represents where the tunica vaginalis and tunica albuginea that encases a testicle folded back in on itself. The identification of a mediastinum in a scrotal lesion implies that testicular tissue is present. This series review presents three cases where PO was identified in the left hemi-scrotum. In addition to the classic homogeneous echotexture that is typically identified in an accessory testicle, a mediastinum was also appreciated in two of the cases, which helped to solidify the diagnosis of polyorchidism.
