ABSTRACT: Modern treatment of inguinal hernias includes prosthetic mesh repairs. However, direct contact of the mesh to the vessels in the inguinal canal and perimesh fibrosis may have a negative impact on testicular flow. The aim of this prospective study was to evaluate the effect of mesh implantation/perimesh fibrosis on testicular flow after repair of indirect inguinal hernias (IIHs).
Forty-eight male patients with unilateral IIH were included. Both testicular parenchyma were assessed using gray-scale sonography, and color/spectral Doppler sonography was performed to evaluate testicular arterial impedance, perfusion, and venous flow. Measurements were made bilaterally at the level of the inguinal canal 1 day before and at the end of the 2nd month after the operation.
There was no difference in testicular and echotexture perfusion between the hernia and the control sides pre- and postoperatively. No venous thrombosis was found. In all groups, resistance index and pulsatility index, measured at 4 levels, were highest in the proximal inguinal canal and lowest at the extratesticular-intrascrotal level (p < 0.05). For all Doppler parameters there was no significant difference between the pre- and postoperative measurements on both the hernia and the control sides.
Mesh implantation/perimesh fibrosis does not adversely affect ipsilateral testicular flow. Mesh application is still a safe procedure in male patients in whom testicular function is important.
