OBJECTIVES: This study aimed to investigate age at surgery for cryptorchidism and to identify factors associated with early surgery.
METHODS: This retrospective study investigated 664 cases of cryptorchidism treated surgically between 2007 and 2023. Early surgery was defined as surgery at less than 1 year old. The cases detected at birth or at the 1-month checkup were defined as early detected cases and age at initial visit less than 6 months old was defined as early initial visit.
RESULTS: The proportion of early surgery increased over time, from 6.3% in 2007-2011 to 30.9% in 2020-2023 (OR 1.67, 95% CI 1.39-2.02; p < 0.001). Multivariate analyses demonstrated that early initial visit, era of surgery, hypospadias and multiple congenital anomalies were independently associated with early surgery. Among 200 early detected cases, 55.5% of these had delayed initial visits (at or over 6 months old). In early detected cases, multivariate analysis demonstrated that the shorter intervals from detection to initial visit and from surgical plan to the date of surgery were independently associated with early surgery. Even among early detected and early visiting cases, some surgeries were delayed due to patient-related factors.
CONCLUSIONS: Age at initial visit is getting earlier, and surgery for cases less than 1 year old is also increasing, but remains insufficient. To achieve earlier surgical intervention for cryptorchidism, an early initial visit is essential. When findings suggestive of cryptorchidism are identified, immediate referral is crucial, and further observation is unnecessary.
