MATERIAL AND METHODS
Men older than 22 years who had either TAO or NTO in childhood for a BUDT were selected.
Participants filled out a questionnaire followed by physical examination, testicular ultrasound, blood
sample and semen analysis. Statistical testing was done using General Linear Modelling.
RESULTS
Sixty seven out of 166 responded. Fifty two completed the questionnaire, 10 (19.2%) reported to
have fathered children. Thirty six showed up for further examination, 26 had TAO and 10 NTO.
Impaired hormonal spermatogenesis regulation (34.6% vs 20%), higher subfertility rate (46% vs
20%) and lower means of motile spermatozoa (58.1x106 spz vs 177.9x106 spz) were observed in
the TAO- vs the NTO group, none of these statistically significant. Four (15.4%) of the TAO- and
2 (20%) of the NTO group have azoospermia.
CONCLUSIONS
Although the operation technique did not have a significant impact on fertility, unfavourable out-
comes were more common after surgery involving the tunica albuginea of the testis. Larger sample
sizes are needed to ascertain if the trends favouring the NTO technique are of any significance.

PURPOSE
Literature has conclusively shown no benefit from radiological investigations for undescended testis
(UDT). We assess the use of radiological investigations prior to referral to paediatric surgery/urology
to quantify resource wastage and clinical impact.
MATERIAL AND METHODS
Retrospective review of children that underwent surgery for UDT (Jan2013 to Jan2016). Patients
without a referral letter for UDT or DSD were excluded. Statistical-analyses: Fisher-Exact & Student
T-test.
RESULTS
Of 425 patients, 169 (40%) underwent radiological investigations pre-referral: 169 ultrasound
scans (USS); 5 MRI. Patients without co-morbidities were more likely to have undergone imaging
(Fisher-Exact:p<0.05).
