Role of US in acute scrotal pain.

BACKGROUND: The acute scrotum is a common emergency department (ED) presentation and can be defined as any condition of the scrotum or intrascrotal contents requiring emergent medical or surgical intervention. Although rarely fatal, acute scrotal pathology can result in testicle infarction and necrosis, testicular atrophy, infertility, and significant morbidity. METHODS: Scrotal US is best performed with a linear 7.5- to 12-MHz transducer. In addition to imaging in the longitudinal and transverse planes, it is helpful to obtain simultaneous images of both testes for comparison. Color Doppler is used to evaluate for abnormalities of flow and to differentiate vascular from nonvascular lesions. Attention to appropriate color Doppler settings to optimize detection of slow flow is critical. RESULTS: The evaluation of acute scrotal pain can be challenging for the clinician initially examining and triaging the patient. Acute scrotal conditions due to traumatic, infectious, vascular, or neoplastic etiologies can all present with pain as the initial complaint. Additionally, the laboratory and physical examination findings in such conditions may overlap; this, coupled with potential patient guarding and lack of collaboration, may result in a limited, non-specific physical examination. Therefore, scrotal ultrasound has emerged to play a central role in the evaluation of the patient presenting with acute scrotal pain. CONCLUSIONS: In conclusion, we are firmly convinced that a scrotal ultrasound should always be performed in the presence of acute scrotal pain. Moreover, urologist should be able to perform a scrotal ultrasound but, if imaging does not supply a clear diagnosis, surgical exploration is still mandatory.

Should older patients be offered varicocoele correction to improve their fertility?

We reviewed a large number of patients from 2000 to 2010 that underwent varicocoele correction using the retrograde sclerotization approach. Three hundred and seventy-six of them were included in the study, as they met the inclusion criteria. Mean age at the time of surgery was 32 years (SD: 6.5); 32% of them were 35 years and older. Patients were classified according to the clinical classification (GC) and Sarteschi's Doppler ultrasound classification (GS). The patients showed up at the clinic after an average time of 30 months of referred infertility related (SD: 28.54). Patients underwent pre-operative assessment with physical examination, sperm analysis and Doppler ultrasound, and again the same assessment at least 3 months after surgery. We evaluated the following parameters: sperm concentration (millions/mL, CONC), percentage motility (a+b, MOT) and the percentage of morphologically typical spermatozoa (MOR). Univariate and Multivariate analysis were performed. The research of Pearson's coefficients was performed to test the correlation between sperm parameters and age, SG, CG. Semen specimens were evaluated according to WHO 1999 criteria. Mean CONC varied from 34.5 to 47.0 millions/mL (+12.5; p < 0.001); MOT from 27.2 to 34.5% (+7.3%; p < 0.001); and MOR from 44.0 to 47.6% (+3.6%; p = 0.001). Univariable and multivariable analysis of variance related to age showed no significant difference of parameters improvement. Pearson's correlation coefficient for pre-operative and post-operative sperm MOT related to patients' age was respectively -0.11 (p < 0.001) and -0.18 (p = 0.04). No other significance was found. Usefulness of treating infertile patients affected by varicocoele is confirmed: varicocoele correction leads to significant sperm parameters improvement. There is no evidence of different improvement related to patients' age. The decline in sperm motility related to age of the patients seems to be only age-dependent: the usefulness of treating patients affected by varicocoele is not influenced by their age: treatment should also be offered to older patients.
