Undescended testis? How best to teach the physical examination

Assessment of diagnostic accuracy for cryptorchidism and risk factors for delayed orchidopexy

OBJECTIVES

Cryptorchidism (CO) diagnosis by palpation is challenging. Patients with suspected CO are primarily referred to pediatric urologists by general pediatricians and urologists. Currently, surgical treatment for CO is recommended earlier than in previous guidelines. In this study, we evaluated factors that lead to diagnosis discordance and delayed orchidopexy in patients referred with suspected CO in addition to timing of initial screening.

METHODS

In total, 731 patients (1052 testes) with suspected CO were included. Risk factors for diagnostic discrepancy in CO diagnosis by pediatric urologists and risk of delayed orchiopexy were evaluated.

RESULTS

Herein, 659 (90%) patients were diagnosed during routine public health checkups for infants and young children, and 419 (57%) patients were referred by pediatric practitioners. Of 1052 testes, 374 (36%) were diagnosed with CO by pediatric urologists. In multivariate analysis, risk factors of diagnostic discrepancy for CO diagnosis by pediatric urologists were bilateral testis (odds ratio [OR] = 9.17, p < 0.0001), >6 months old at initial diagnosis (OR = 1.036, p < 0.0001), and pediatric referral (OR = 4.60, p < 0.0001). In total, 296 patients underwent orchiopexy for CO. In multivariate analysis, risk factors for delayed orchiopexy were presence of comorbidities (OR = 3.43, p = 0.003) and >10 months old at referral (OR = 12.62, p < 0.0001).

CONCLUSIONS

Pediatric referral is a risk factor for discordant CO diagnostics, and late age at referral brings a risk of delayed orchiopexy. It is necessary to enlighten pediatricians, who are mainly responsible for routine health checkups, in teaching CO diagnostic techniques to ensure early referral.

Validation of Physical Examination Perceived Self-Efficacy Instrument for Undergraduate Nursing Students

BACKGROUND

Numerous studies have revealed that nursing students perceive lack of confidence as one of the key barriers to performing physical examination; however, it is not empirically measured. This study aimed to test the psychometric properties of the Physical Examination Perceived Self-Efficacy Instrument.

METHOD

The study included three phases: in Phase 1, 51 items were constructed; in Phase 2, 7 field experts rated items for relevancy; and in Phase 3, the instrument was piloted to a convenience sample of 238 students.

RESULTS

The analysis yielded six factors with a factor loading >0.40. The corrected item-total correlation ranged from 0.6 to 0.87. Cronbach's alpha ranged from .84 to .98. The interscale correlation of the instrument was statistically significant (p < .001).

CONCLUSION

We found that the instrument is a psychometrically robust measure of self-efficacy of performing physical examination. The instrument could provide a better understanding of the association between perceived self-efficacy and students' academic performance. [J Nurs Educ. 2022;61(1):36-40.].

Guideline implementation for the treatment of undescended testes: Still room for improvement

BACKGROUND

Early orchidopexy (OP) around the age of 1 year is recommended in boys with congenital undescended testis (UDT) worldwide since decades. Former retrospectives studies did not distinguish congenital from acquired UDT with a consecutive negative bias concerning the age at surgery.

METHODS

In a retrospective analysis, data of all boys who underwent OP in eight pediatric surgery institutions from 2009 to 2015 were analyzed. Congenital or acquired UDT were differentiated. Patients were categorized into 3 groups of age at surgery: (1) <12 months, (2) 12-24 months, (3) >24 months. Data of one institution were analyzed in detail: exact age of first referral, exact age at surgery, intraoperative findings.

RESULTS

Out of 4448 boys, 3270 boys had congenital UDT. In 81% (2656 cases) surgery was performed beyond the age of 1 year, in 54.4% (1780) beyond the age of 2 years. chi-Square statistics showed a higher rate of early operations in hospitals compared to outpatient services and in Germany compared to Switzerland. In 694 congenital detailed cases, median age at referral was 13 months [range 0-196], median age at surgery was 15 months [range 0-202].

CONCLUSION

Delayed referral is the main reason for guideline non-conform delayed surgery in UDT.
