Insights
Most boys with undescended testis (UDT) are operated on after one year of age, despite early diagnosis. Premature infants and those with genitourinary anomalies receive earlier surgical intervention for UDT.
Area of Science:
- Pediatric Surgery
- Urology
- Andrology
Background:
- Undescended testis (UDT) affects 1-6% of males, with current recommendations for surgical correction by one year of age.
- Timely intervention for UDT is crucial to minimize risks of infertility and malignancy.
Purpose of the Study:
- To analyze population characteristics of children managed for UDT.
- To determine age at referral and orchidopexy for UDT.
- To identify referral patterns influencing surgical timing.
Main Methods:
- Retrospective review of 513 boys with 576 undescended gonads operated for UDT between 2007 and 2011.
- Data collected included demographics, diagnosis, referral source, and age at referral and orchidopexy.
- Statistical analysis of referral and surgical timing based on patient characteristics and referral source.
Main Results:
- The median age at referral was 1.1 years and at orchidopexy was 1.6 years.
- Congenital UDT was diagnosed in 56% of cases; 70% of these were operated on after one year of age.
- Premature infants and those with genitourinary anomalies were referred and operated on earlier; patients from public tertiary hospitals had earlier referrals.
Conclusions:
- Despite early diagnosis, the majority of UDT cases, including congenital ones, are referred and operated on beyond the recommended age of one year.
- Prompt referral is essential, particularly for premature infants and those with associated anomalies.
- Community health initiatives should focus on emphasizing timely referral to mitigate the impact of delayed orchidopexy.
Objective:
Undescended testis (UDT) affects 1-6% of males. Current recommendations are to correct maldescent by 1 year of age. We identify the population characteristics of children referred and managed for UDT, age at referral and orchidopexy, and patterns of referral.
Design, Setting And Patients:
Retrospective 5-year review of all patients operated for UDT from 2007 to 2011 in our institution. Patient demographics, neonatal diagnosis of UDT, age at referral, referral source and age at first orchidopexy were recorded. Data are reported as median (range).
Results:
There were 513 boys with 576 undescended gonads; 450 (88%) had unilateral UDT. Congenital (present at birth) UDT was diagnosed in 287 (56%) children. Seventy-nine (15%) were premature births, 41 (8%) had associated major genitourinary abnormalities. Median age at referral was 1.1 (0-16.2) years; median age at first orchidopexy was 1.6 (0-17.2) years. When corrected for age, those with a history of prematurity and associated major genitourinary malformations were referred and operated on earlier. There was no difference in age at referral and orchidopexy when comparing unilateral versus bilateral maldescent, and palpability of UDT. Of those with congenital UDT, 70% were operated at beyond 1 year of age. Those referred from public tertiary hospitals were younger than those referred from community clinics (p<0.0001) and private healthcare institutions (p=0.003).
Conclusions:
Despite early diagnosis in many patients with UDT, most are referred and operated after 1 year of age, even in congenital UDT. Premature babies, those with major genitourinary anomalies, and those seen in public tertiary hospitals are referred earlier. Community health initiatives must emphasise prompt referral to allay the impact of delayed surgery.
