It is reported that ~50% (range 28-75%) range of paediatric patients with Spigelian hernias will have ipsilateral cryptorchidism 1,2.
Spigelian hernia occurs with the failure of the development of the gubernaculum, which in turn halts the development of the inguinal canal and further descent of the testis from its intra-abdominal position to the scrotum. The arrested testis induces a sort of "rescue canal" through a weak area in the abdominal wall in the absence of inguinal canal resulting Spigelian hernia 1.
