340 Relationship between undescended testis position and prevalence of testicular appendices, epididymal anomalies and patency of processus vaginalis

The Journal of Sexual Medicine, 2018

Objectives. To assess the incidence of testicular appendices (Tas), epididymal anomalies (EAs), and processus vaginalis (PV) patency in patients with undescended testis (UT) according to testicular position and to compare them with human fetuses. Methods. We studied 85 patients (108 testes) with cryptorchidism and compared the features with those of 15 fetuses (30 testes) with scrotal testes. We analyzed the relationships among the testis and epididymis, patency of PV, and the presence of TAs. We used the Chi-square test for statistical analysis (< 0.05). Results. In 108 UT, 72 (66.66%) had PV patent, 67 (62.03%) had TAs, and 39 (36.12%) had EAs. Of the 108 UT, 14 were abdominal (12.96%; 14 had PV patency, 9 TAs, and 7 EAs); 81 were inguinal (75%; 52 had PV patency, 45 TAs, and 31 EAs), and 13 were suprascrotal (12.03%; 6 had PV patency, 13 TAs, and 1 EAs). The patency of PV was more frequently associated with EAs (= 0.00364). The EAs had a higher prevalence in UT compared with fetuses (= 0.0005). Conclusions. Undescended testis has a higher risk of anatomical anomalies and the testes situated in abdomen and inguinal canal have a higher risk of presenting patency of PV and EAs.

Epididymal-testicular fusion anomalies in cryptorchidism are associated with proximal location of the undescended testis and with a widely patent processus vaginalis

Journal of Anatomy, 2014

Past studies documented the presence of epididymal/testicular fusion anomalies and persistence of a patent processus vaginalis in a small case-series of cryptorchid and/or hydrocele patients. The primary aim of this study was to determine the prevalence of the epididymal/testicular anomalies in a series of more than 1000 cryptorchid patients compared with controls. Secondary aims were: (i) to investigate the association between the cryptorchidism and the patency of p. vaginalis; and (ii) to correlate the epididymal/testicular fusion anomalies with the position of the testis and with the patency of the p. vaginalis. The clinical and surgical data of 1002 cryptorchid patients and 230 controls were retrospectively retrieved and analysed. Epididymal/testicular fusion anomalies were classified as: (i) normal anatomy; (ii) minor anomalies; and (iii) major anomalies. Statistical analysis was performed using the Student's t-test and Chi-square tests. The prevalence of the epididymal/testicular fusion anomalies was higher in the cryptorchid group compared with that of the control group (minor and major anomalies in cryptorchids vs. controls, respectively: 42.2 vs. 5.6% and 9.3 vs. 1.6%, P < 0.0001). Moreover, we documented a correlation of these anomalies with a more proximal localization of the testis (minor and major anomalies in proximal vs. distal location of the testis, respectively: 62.5 vs. 34.8% and 19.1 vs. 6.3%, P < 0.0001) and with the persistence of a widely patent p. vaginalis (minor and major anomalies in widely patent p. vaginalis vs. narrow duct, respectively: 51.7 vs. 42.2 and 11.9% vs. 7.8%, P < 0.001). In conclusion, the epididymal/testicular fusion anomalies were strongly associated with cryptorchidism and the persistence of a widely patent peritoneal vaginal duct. Although it remains unclear whether these anomalies cause non-descent of the testis or, conversely, result from the cryptorchidism or from the persistence of a widely patent duct, our data re-enforce this association.

Significance of epididymal and ductal anomalies associated with undescended testis: Study in 652 cases

Urology, 1994

We have long been interested in epididymal and ductal anom. alies associated with cryptorchidism in the literature. We decided to study their prevalence in our cases due to the significance of these anomalies in patients' future fertility. Methods. We studied six hundred fifty-two testes treated for failed descent in our department and evaluated the epididymal and ductal anomalies we observed intraoperatively. Results. Epididymal and vasal anomalies occurred with an overall frequency of 36 percent (235 of 652 cases). Flimsy attachment of the head of epididymis to the testis constituted the most common anomaly. Conclusions. The prognosis of future fertility should consider the epididymal anomalies detected at orchiopexy. Such anomalies may coexist with excellent testis histology so that fertility impairment may occur based on sperm transport, despite the preservation of germ cells by early orchiopexy

Structural analysis of testicular appendices in patients with cryptorchidism

International braz j urol : official journal of the Brazilian Society of Urology

Report the incidence and structure of testicular appendices (TAs) in patients with cryptorchidism, comparing their incidence with epididymal anomalies (EA) and patency of the vaginal process (PVP) and analyzes the structure of TAs. We studied 72 testes of patients with cryptorchidism (average of 6 years), and 8 testes from patients with hydroceles (average of 9 years). We analyzed the relations among the testis, epididymis and PVP and prevalence and histology of the TAs. The appendices of 10 patients with cryptorchidism and 8 with hydrocele were dissected and embedded in paraffin and stained with Masson trichrome; Weigert and Picro-Sirius Red with polarization and immunohistochemistry analysis of the collagen type III fibers to observe collagen. The stereological analysis was done with the software Image Pro and Image J, using a grid to determine volumetric densities (Vv). Means were statistically compared using the ANOVA and unpaired T test (p < 0.05). Of the 72 testes with cryp...

Overview of Epidemiology and Management of Undescended Testis (Cryptorchidism)

Journal of Pharmaceutical Research International

Cryptorchidism (undescended testis, maldescendus testis) is a disorder in which one or together testes miscarry to slope into the bottommost of the scrotum. The study aimed to summarize the updated evidence regards, epidemiology, etiology, classification, diagnosis, and treatments of Cryptorchidism or undescended testis. Several causes can result in developing cryptorchidism. Disruption of any phase of testicular prolapse due to genetic hormonal, structural, ecological, or social issues can lead to cryptorchidism. The diagnosis of undescended testes is clinical. The test should be performed by an experienced person and should always be performed using a two-way technique. In some cases, imaging diagnostics for cryptorchidism may be helpful. The rationale for treating cryptorchidism is to reduce the risk of its long-term consequences. Current treatments for undescended testes include hormone therapy, orchopexy, and surgical correction.

Epididymal disjunction anomalies in undescended testis – a factor associated with spermatic obstruction

International braz j urol, 2022

Background: To analyze the incidence of epididymal anomalies (EAs) associated to spermatic obstruction in patients with undescended testis (UT) according to testicular position and age. Materials and Methods: We studied 87 patients (110 testis) with cryptorchidism and analyzed the presence of EAs correlated with the testicular position, age and patency of the processus vaginalis (PV). To analyze the relations between the testis and epididymis we considered three situations: (a) Normal pattern: the epididymis was attached to the testis at the head and tail and epididymis totally attached to the testis; (b) EAs: when the epididymis was attached to the testis only at the head (Figure-1A) and (c) EAs associated to spermatic obstruction: epididymis was attached to the testis only at the tail (Figure-1B) and when there are no visible connection between testis and epididymis (Figure-1C). We used the Wilcoxon-Mann-Whitney test and the Chi-square test for contingency analysis (p <0.05). Results: The mean age of the patients was 5.18 years (SD=2.867). Of 110 testes analyzed, 14 were abdominal (12.72%); 83 inguinal (75.45%) and 13 suprascrotal (11.81%). Normal relationships between testis and epididymis were observed in 54 patients (62.1%) with no significant differences in relation to the patient's age (p=0.666). Epididymal tail disjunction was observed in 23 patients (26.44%), with no significant differences in relation to age (p=0.59). EAs associated to spermatic obstruction were observed in 16 patients (18.4%), also with no significant differences in relation to age (p=0.684). We did not observe significant correlation between the testis position and the incidence of EAs (p=0.119). We did not observe significant correlations between patency of the PV (64.7%) and incidence of EAs (p=0.742). Conclusions: Epididymal anomalies associated with spermatic obstruction are present in almost 20% of undescended testes, without significant correlation with age, testicular position and patency of the PV. This information needs to be correlated to the infertility risk of this congenital anomaly.

The undescended testis: diagnosis, treatment and long-term consequences

Deutsches Ärzteblatt international, 2009

The late descent of a testicle into the scrotum may impair its development. Reduced fertility is the main risk of primary cryptorchidism even after timely treatment, as histopathological changes (Leydig cell hypoplasia) already become apparent in the first few months of life. There is evidence, however, that treatment is often delayed. Hormonal and surgical treatments complement each other and should be provided before the child's first birthday. Selective literature search in PubMed (January 2008) based on the following keywords: "cryptorchidism", "maldescensus testis", "etiology", "therapy", "semen quality", "testicular cancer". Particular attention was paid to the current S2 guidelines on cryptorchidism. Hormone therapy is the best initial treatment in most cases, with a few exceptions. If this is unsuccessful, surgery should be performed without delay. The success of treatment depends on the initial position of the ...
