“…Another retrospective published study reported surgical findings of PPV in 23% of boys over 5 years of age with late-presenting acquired calescent versus 84% in children aged less than 5 years of age with early-presenting maldescent (overall prevalence 50%) (13). Similar results were obtained by other authors who found a prevalence of surgically determined PPV (16). A very interesting paper focusing on the role of PV in cryptorchidism reported a surgically determined PPV prevalence of 31% in a group of patients who had not responded to hormone treatment versus 56% in patients who had not received such treatment before surgery (17).…”

Objective: To clarify the role of peritoneography in assessing the patency of processus vaginalis (PV) in pediatric patients diagnosed with cryptorchidism. Materials and Methods:We designed a prospective clinical trial to evaluate the patency of PV in boys presenting cryptorchidism. Herniography was performed in 310 prepubertal boys. Data about the morphology of PV was compared with operative findings in those surgically treated patients. Retractile and ectopic testes were excluded from the study. Results: Of the 376 undescended testes (310 patients), 281 cases were associated with an obliterated PV. Herniography revealed 95 cases of open PV in cryptorchid boys. The 244 normally descended testes had associated patent processus vaginalis in only 31 cases. Conclusions: Herniography is the most relevant procedure for accurate diagnosis of persistent PV. The persistence of PV was significantly more frequent when the position of the testes is more cranial. The incidence of an open PV decreases with age.

The processus vaginalis is a blind‐ended evagination of the abdominal wall that develops during fetal life and typically undergoes obliteration in early life. Persistence of the processus vaginalis is associated with a number of pathologies including congenital indirect inguinal hernias, communicating hydroceles, funicular and encysted hydroceles, canal of Nuck cysts, and acquired undescended testis. Whilst all are detectable sonographically, there is little educational material relevant to the field of ultrasound with much of the literature directed at surgical and primary care physicians. Furthermore, within the literature there is a lack of consensus on several areas including the anatomy and embryology of the processus vaginalis and the mechanisms behind its obliteration. As such the objective of this paper is to distil the information regarding the persistent processus vaginalis as it is relevant to ultrasound and in doing so address the literature gap for sonographers and sonologists. The anatomy and embryology of the persistent processus vaginalis will be discussed including causative mechanisms for anomalies with their sonographic appearance highlighted.

“…Surgical findings reported earlier include an abnormal attachment of the gubernaculum in 80% to 83% [12,13] and a patent processus vaginalis in 52% to 87% [12][13][14][15]. In these studies, the ages of the patients varied between 2 months and 33 years, and no distinction was made between congenital and acquired UDT.…”

Relationship between the persistence of the processus vaginalis and age in patients with cryptorchidism

Abstract: There was no difference in the occurrence of patent processus vaginalis between the various age ranges under study. Patent processus vaginalis was more frequent in patients with cryptorchidism than in fetuses.
