OBJECTIVES To assess if there is an age group where the occurrence of persistent processus vaginalis is more frequent in patients with cryptorchidism. MATERIALS AND METHODS We studied 24 fetuses with gestational age between 23 and 35 weeks postconception (control group) and 102 patients (137 testes) with cryptorchidism aged between 1 and 33 years (mean 10.3 years). We considered 2 situations ...

PURPOSE We performed low scrotal approach orchiopexy in patients with prescrotal cryptorchidism. The processus vaginalis was not ligated if it was not widely patent. We retrospectively evaluated the long-term outcomes of low scrotal approach orchiopexy without processus vaginalis ligation. MATERIALS AND METHODS A total of 137 patients (227 testes) were diagnosed with prescrotal cryptorchidism...

BACKGROUND Ligation of a patent processus vaginalis via the inguinal approach is the standard operative technique for the treatment of hydroceles in infants and children. Although a simple technique, identification of the processus vaginalis can be difficult even for the experienced surgeon. AIMS To investigate the use of methylene blue in the perioperative identification of the patent proces...

BACKGROUND AND OBJECTIVES Negative contralateral groin exploration for childhood hernias raises the question of whether contralateral groin exploration is necessary or not. To find out whether a contralateral processus vaginalis was patent, we performed laparoscopy with a flexible scope. METHODS After carbon dioxide insufflation, a flexible laparoscope was inserted through the opened hernia s...

Acute obstruction of a patent processus vaginalis occurred in two boys, mimicking incarceration of an inguinal hernia. In fact, obstruction was caused by an intussusception of the processus vaginalis forming an intussuscipiens that occluded the hernia sac. This lesion, described previously in 1896 and in 1974, is one of the mechanisms by which an asymptomatic hernia or hydrocele becomes acutely...

The epididymal anomalies and patent processus vaginalis are frequently seen in patients with cryptorchidism or hydrocele. We performed a prospective study on the relationship between the epididymal anomalies and the patency of the processus vaginalis in boys with hydrocele (190 cases) or cryptorchidism (89 cases) who were treated from August 1997 to February 2000 (mean age, 51 months; range, 12...

The processus vaginalis within the inguinal canal forms the canal of Nuck, which is a homolog of the processus vaginalis in women. Incomplete obliteration of the processus vaginalis causes indirect inguinal hernia or hydrocele of the canal of Nuck, a very rare condition in women. Here, we report 2 cases of hydrocele of the canal of Nuck that were diagnosed with ultrasonography in both cases and...

Epidermal cyst is a benign tumor that grows slowly and develops from entrapment of epidermis into the dermis. Inguinal canal is an extremely unusual location for an epidermal cyst in children. Here in, a 6-year-old girl presenting with inguinal mass which was diagnosed to be epidermal cyst in the patent processus vaginalis sac is reported. To the best of our knowledge, it is the first case of e...

PURPOSE We examined the significance of the CAG repeat polymorphism in the pathogenesis of cryptorchidism. MATERIALS AND METHODS Genomic deoxyribonucleic acid (DNA) was extracted from blood samples from 42 cryptorchid boys and from 31 non-cryptorchid control subjects. In the cryptorchid group, 7 had bilateral cryptorchidism and 6 had patent processus vaginalis in the contralateral side. To de...

OBJECTIVE To prospectively evaluate the Bianchi single scrotal incision technique for orchiopexy in boys with palpable undescended testis. METHODS A total of 35 orchiopexies were performed in 28 patients. The patent processus vaginalis was dissected and cut high without ligation, while in Bianchi's original procedure, the patent processus vaginalis is dissected up to the external inguinal can...
