“…Fourth, color Doppler and contrast-enhanced ultrasound were the only imaging modalities available in this series because MRI was not performed. Although according to Bilagi et al [1], MRI is not needed to characterize segmental testicular infarction [1], other authors [5,[9][10][11]26] suggest that this technique is excellent for establishing the diagnosis in equivocal cases.…”

Recognition of lobular morphologic characteristics and the presence of perilesional rim enhancement at contrast-enhanced ultrasound can increase confidence in the diagnosis of segmental testicular infarction compared with reliance on gray-scale and color Doppler findings. Changes in lesion features during follow-up confirm the differential diagnosis from other testicular lesions and allow conservative management.

Organ-sparing approaches for testicular masses

2010

View full text Add to dashboard Cite

Organ-sparing approaches are currently practiced in urology for many malignancies. Partial orchiectomy of germ cell tumors (GCT) provides potential benefits over radical surgery by reducing the need for androgen substitution, lessening psychological stress, and preserving fertility, with a durable cure rate. Furthermore, many testicular lesions detected clinically or by ultrasonography will be benign, in which case radical orchiectomy represents overtreatment. Partial orchiectomy for benign lesions allows preservation of endocrine and exocrine function, and reduced risk of local recurrence. However, selection criteria are not clear and one must always be suspicious that a GCT might exist. Carcinoma in situ that remains in the salvaged testicle is a challenge to treat. Radiation therapy is an option, although there is a high chance that patients will subsequently require hormonal replacement. Partial orchiectomy should be undertaken only in selected patients--men with bilateral testicular cancer or GCT in a solitary testis--if the size and location of the mass are amenable to surgery. Informed patient consent discussing radical orchiectomy as the gold standard is mandatory, and discussion of the risks associated with CIS and its treatment, as well as the need for androgen supplementation are paramount. Alternative strategies of organ preservation, such as radiotherapy, HIFU and chemotherapy, might be appropriate treatment options in the future. However, the safety and efficacy of these procedures needs to be demonstrated in comparison with partial orchiectomy in larger and prospective studies with longer follow-up.

Purpose: Proton magnetic resonance spectroscopy (1 H-MRS) has been proposed as a tool to assess male infertility providing metabolic signatures related to the spermatogenesis in the testis. This study sought to identify the role of 1 H-MRS in the diagnosis of infertility in patients with semen analysis altered. Materials and Methods:14 patients (27 testicles) with fertility problems and with an altered semen analysis (5 oligospermia, 3 asthenospermia, 6 oligoasthenospermia) and 9 controls (18 testicles) with normal spermatogenesis assessed (men with prior paternity and normal semen analysis) and normal testicles at magnetic resonance (MR) and ultrasonography (US) with colour Doppler (CD) examination were included. All patients underwent testis US and CD investigation, conventional MR examination at 1.5T including T1 and T2 weighted images in three orthogonal planes and proton magnetic resonance spectroscopy (1 H-MRS) with single-voxel PRESS (TR 2000 ms / TE 31 ms). Major metabolites peaks (choline, creatine, lipids, lactate) were calculated and compared between the patients and controls.Results: Mean choline peak in the semen analysis altered group was statistically significantly lower than the normal group (0.69 vs 1.34, 95% CI: 0.52 -0.85; p < 0.001). 18 testicles within semen analysis altered group (66,7%) had both MR and US examination negative but mean choline peak lower then controls (1.09 vs 1.34, p < 0.001). 7 testicles of those presented also varicocele at CD investigation. Conclusion:1 H-MRS revealed a significant shift towards lower choline peak in patients with semen analysis altered compared to controls with normal spermatogenesis. Moreover 1 HMRS provided to find out spermatogenesis disorder in patients with normal testis at MR and US examination.
