“…Studies describing UDT rates at different ages were counted separately. Sixteen of the 46 included articles reported UDT rates at several age groups (see Table 1) (King, 1934; Drake, 1934; Williams, 1936; McCutcheon, 1938; Johnson, 1939; Smith & Camb, 1941; Baumrucker, 1946; Ward & Hunter, 1960; Cour‐Palais, 1966; Mital & Garg, 1972; Borghans‐Delvaux et al. , 1976; Blom, 1984; Onuora & Evbuomwan, 1989; Yücesan et al.…”

“…There was considerable variation in definitions used among studies. Five of the 46 (10%) articles were based on the definition given by Scorer (1964) (Mital & Garg, 1972;John Radcliffe Hospital Cryptorchidism Research Group, 1992;Berkowitz et al, 1993;Boisen et al, 2004). Nineteen articles (instead of 18) were based on a definition by position since the John Radcliffe Hospital Cryptorchidism Research Group used the definition given by Scorer as well as by position.…”

We performed a systematic review and critique of the literature on the frequency of undescended testis (UDT) among boys from birth to adolescence. Special attention was given to whether previous testicular position was taken into account to distinguish between congenital and acquired UDT. We searched Medline, Embase, Cinahl and the Cochrane Library. Any study reporting on the frequency of UDT was included. Study population age, number of boys studied, period of examination, primary examiner, area of study, study design, ethnicity, definitions used and previous testicular position were analysed. A total of 46 studies met the inclusion criteria. Twenty-three of the 46 (50%) studies involved newborns. Definitions were described in half of the studies; however, the definitions used were heterogeneous. Previous testis position was described in 11% (5/46) of the studies. At birth, in term and/or birth weight >2.5 kg infants, the UDT rate ranged from 1.0 to 4.6%, and in premature and/or birth weight <2.5 kg infants from 1.1 to 45.3%. At the age of 1 year UDT in term and/or birth weight >2.5 kg infants was seen in 1.0-1.5%, at 6 years in 0.0-2.6%, at 11 years in 0.0-6.6% and at 15 years in 1.6-2.2% of boys. The frequency of UDT shows variable figures in the literature. The actual frequency of acquired UDT essentially remains unclear because of the shortage of studies performed at an older age, and of studies reporting on previous testicular position.

“…Early diagnosis and treatment of undescended testis, from 3 to 6 months, conserve fertility and preclude testicular malignancy (D'cruz & Das, ; Docimo, Silver, & Cromie, ). The correct treatment is still controversial, debated among paediatric surgeons (Davenport, ; Mital & Garg, ). A literature review was provided to compare the laparoscopy and open surgery for children.…”

Multi Criteria Decision Anal

View full text Add to dashboard Cite

This study is designed to provide paediatric surgeons' perspectives on the relative importance of the criteria for choosing a surgical mode for undescended testicle treatment between open surgery (orchiopexy) or laparoscopic surgery and determine the suitable surgical mode by using the multicriteria decision‐making method. The analytic hierarchy process (AHP), the technique for order preference by similarity to ideal solution (TOPSIS), and Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) methods are utilized. A decision hierarchy is set with a goal, criteria, and alternatives. Our model is developed on the basis of four main criteria (time‐related, patient‐related, recovery‐related, and complication‐related factors) and 11 subcriteria (operation duration, length of stay in hospital, preoperative preparation time, recovery period after surgery, age of patient, weight of patient, aesthetic appearance, quality of life satisfaction, recurrence, possibility of infection, and vital function) as well as two alternatives, laparoscopy and open surgery. An online questionnaire was sent to the paediatric surgeons; responses from the 31 experts (i.e., paediatric surgeons) indicate that the most important criteria are found to be the time‐related factors, especially preoperative preparation time. On the other hand, the least important criteria are found to be complication‐related factors. Moreover, laparoscopy is chosen as the most suitable method for the undescended testicle using the AHP, TOPSIS, and VIKOR methods. This study helps paediatric surgeons' decision making by elucidating their priority criteria and representing their decision‐making process in terms of quantity with the help of AHP, TOPSIS, and VIKOR methodologies.

“…Several studies have described low birth weight and preterm delivery as the major risk factors for cryptorchidism [ 19 ]. In prospective studies using similar and clearly defined criteria of cryptorchidism, the birth rate of cryptorchidism has varied between 1.6 and 9.0% in USA [ 20 ], Denmark [ 21 , 22 ], Finland [ 21 ], Italy [ 23 ], India [ 24 ], Lithuania [ 25 ], UK [ 17 , 26 ], and Malaysia [ 27 ]. It is the most significant risk factor for testicular cancer increasing the risk 2.5–11-fold [ 28 ].…”

Vitamins E and C Alleviate the Germ Cell Loss and Oxidative Stress in Cryptorchidism When Administered Separately but Not When Combined in Rats

2012

The antioxidant effects of vitamins C and E on cryptorchidism-induced oxidative stress were investigated in male Sprague-Dawley rats. Forty rats (200–250 g) were randomly divided in a blinded fashion into five groups (n = 8). Group 1 was sham operated and treated with vehicle (corn-oil, 10 mL/kg). Groups 2, 3, 4, and 5 were rendered unilaterally cryptorchid and treated with vehicle (10 mL/kg), vitamin E solution (75 mg/kg), vitamin C solution (1.25 g/kg), and combination of vitamin E (75 mg/kg) and vitamin C (1.25 g/kg) solutions, respectively. Germ cell count, superoxide dismutase (SOD), total protein (TP), and testicular weight (TW) were lower, but malondialdhyde (MDA) was higher in the cryptorchid rats than the sham-operated rats. When administered separately, vitamins C and E increased germ cell count, SOD, TP, and TW but did not reduce MDA in the cryptorchid rats when compared to the vehicle-treated cryptorchid rats. However, there was no significant difference in these parameters between vehicle-treated and combined vitamins C- and E-treated rats. This suggests that vitamins E and C alleviate the germ cell loss and oxidative stress in cryptorchidism when administered separately but not when combined in rats.
